Deep-farm digital step hardware has been measured for many years, and electric cars have long become the most common short-distance travel tool for the vast majority of ordinary people to travel daily, buy food and travel, with almost one home. Many of my friends have been riding electric cars for three or four years, travelling for dozens of kilometres every day, but have never been careful as to which wheel is controlled by the handles of the two brakes on the right or the left。
The majority of the population has adopted the habit of random brakes: the right hand squeezes the right hand, and in emergency situations, the mind squeezes, all by instinct. A number of riders have always given priority to the front brakes, seemingly faster, while hiding the risks of slippages and rollers; others have dared only to squeez the back brakes, which are significantly longer and cannot be held in a state of emergency. The correct division of power-driven brakes and the standard operation of different road conditions are presented today, taking into account the national standard for electric bicycle brakes, multiple road surveys and years of experience in the maintenance of doors。
In full, all brake distance data and brake structure norms are based on the official criteria of the national standard gb 17761-2018 " technical instructions for the safety of electric bicyclists " . All cycling techniques are validated by realistic measurements of dry land, rain, slopes, not exaggerating danger, not creating anxiety, but creating a positive perception of safe travel and rational use of vehicles for the sake of scientific and practical motor vehicle safety。
Basic common sense: harmonization of national standards, left, back, right, forward, 90% rider against priority
Many ride their first mistakes for many years: it is assumed that the right and right brakes are only a matter of the right and right hand habits, and that there is little difference in power. In fact, all of the new state-compliant electric bikes in the country are subject to uniform design standards: the left hand vehicle sets the brake handle = the rear brake, the right hand sets the brake handle = the front wheel brake。
In terms of power allocation, the front brakes bear about 70 per cent of the brake effect on the vehicle as a whole, while the rear wheel is responsible for 30 per cent of the power, which is why the car is parked faster than the right front brake alone. Day-to-day measurements are also intuitive: the national sign is at 25 km/h and dry road surfaces are squeezed separately. The brake distance can be up to 15 m; the brakes can be used together, and the brake distance can be reduced to less than 7 m, and the gap is clear。
The most common habit of daily wrongs: squeezing the front brakes on the right hand in the first moments of danger. When vehicles travel at high speed, inertia allows the entire centre of gravity to move forward in an instant, with a significant reduction in the back-wheeling power, and the loss of rolling friction in the case of a front wheel when it dies, the high risk of side-sliding, ablaze and the most significant cause of a motor vehicle crash. Turning back the brakes, which are more stable, even if held tight, at most with a slight tailing of the rear wheel, is far less likely to lose control of the whole vehicle than the previous brake。
A simple summary of the basic principles: daily flat deceleration gives priority to the left-hand brake, emergency brakes follow "left-to-right, light-to-right" and never press the right-hand front-wheel brake alone。
Day-to-day smooth commute: normal circuits, slow speeds, standard brake operations
The flat scenes of daily urban road commuting at around 20 km/h, pre-calculation of parking, red lights such as junctions, etc., are dominated by smoothing of the core of brakes, saving of electricity and protection of brake blades。
Regular side-drives and slow-downs for pedestrians: only left-hand rear brakes will be used for the entire journey, slowly and gradually, and the speed of cars will be steadily reduced, without any need for front brakes. The operating body is the most stable, with no forward nodes, more even wear and tear on brakes, long-term use of the brakes and drums, and reduced later maintenance costs。
For the sake of economy, many people are squeezing the right front each time they stop, without seeing the problem in the short term, causing excessive losses to the front brakes over the long term, overburdening the front axis, and causing a resonance of brakes and power decline in six months to one year. Daily, non-emergency situations, with a single left-back brake, are the most commonly used power-saving, car-protective operations of old riders。
Iii. Emergency emergency: foreign destructions, foreign strengthenings, strengthenings
It was a very dangerous mistake for many people to use their hands to choke the brakes in the face of such emergencies as parking and crossing the street. The correct emergency brake step is divided into three steps, which are simple to remember:
1. The first step is to squeeze the left hand behind the wheel brakes, slowly apply the force to stabilize the body, first remove some of the speed of the car and avoid the instant forward movement of the centre of gravity
2. After a back-wheel deceleration of 1-2 seconds, a little bit of the front brake on the right hand, gradually increasing the grip and reducing the distance of the brakes by using the front-wheel main power
3. It is prohibited to strangle the front brakes at once and to use the brakes in such a way as to tighten and slightly release repeated operations to prevent the front wheel from slipping。
According to measurements, 25 km/h per hour, which regulates the sequence of brakes, with near-full braking efficiency, the body stability is twice as high as that of the direct hand brakes, which can significantly avert the risk of slide and fall. For starters, mid-aged riders, there is no need to force memory skills, and remember that "first left, then right hand, the front brakes don't die" are enough to deal with most emergency scenarios。
Iv. Special road-specific techniques: slopes, rain, bends, brakes are completely different
The scene of the highest daily risk of riding was never flat, but rather the slopes, the rain, the wet slopes, the turning sections, and the need for flexibility in the prioritization of different road brakes, which were easily overlooked by many old riders。
1. Long-down slope segment: full-scale backbrand control, with a strict ban on downhill front brakes
The heavy weight of the front wheel would have been larger at a time when vehicle self-esteem would continue to accelerate and the focus would have been natural forward. If the right front brakes are often squeezed down the slope, there is a high risk of pre-wheel fever decline and death. The right way down the slope: the front door slides in advance, the left-hand rear brakes are used to control the speed of the car, the speed of the car is up to 15 km/h, and a slight front brake is required when the speed is sorely slowed, the centre of gravity is leaning back, the hip is moved back, and the back-wheel grip is further boosted。
2. Rainfall days to build water surface: less front brakes, mainly brakes, rear wheeling
There was a significant decline in friction on the road in the rainy days, with brakes more than twice as far as the dry road surface, and zebra lines, well covers and white line positions being particularly wet. The principle of cycling in the rainy days: as early as possible, without an emergency brake, without brakes; when it is necessary to slow, it must rely almost on a left rear-point brake, which is only minimally assisted, it is absolutely impossible to squeeze the right front brake with one hand, and the probability of the wheel sliding in front of the wet slide is multiplied。
3. Turning, bending process: slowing in advance of entry and no heavy brakes inside the bend
The car itself is tilted at the turn, the horizontal grip of the tires deteriorates, and the hard brakes within the bend are easily flipped. (b) regulation: the brakes are used before entering the bend, which are used to speed down, and the brakes are held back only slightly, until the turn back to the car is completed, and then the brakes are stopped。
V. Long-term use of the wrong brakes, resulting in three hidden disadvantages: car injury, electricity consumption, reduced safety
Many feel that brakes are a different habit, at best affecting security, and that long-term priority is given to single-handed front brakes, which also accelerate vehicle wear and tear and increase the cost of day-to-day vehicles。
First, the front brakes were excessively worn and the frequency of replacement doubled. The front wheel carries most of the power, often using the front brakes on its own, grinding the brakes to the alert line for several months, and the brake type is prone to brake grinding, noise and increased maintenance costs. The back brakes are more even and the rate of wear and tear is more flat。
Second, a fork, a long-term bearing of the front wheel bearing, and the entire vehicle protected against seismic variations. Each flash-forward, the force of the shock directly affects the front wheel, the bearings and, over time, the front fork is loosed, the pits sound, and the whole vehicle rides down。
Third, more electricity before inertia. Frequent brakes, heavy forward brakes, fast and slow speeds, frequent electric power speeds, same commuting distances, the habit of wrong brakes that allow electric cars to continue with small water contractions, and a marked gap in accumulated electricity costs。
Rational view: science allocates the right and right brakes, not only safer riding, but also lowers the cost of vehicle maintenance, which is a practical vehicle technique for low-cost step-up experiences。
Vi. New entry habits: 3 minutes of standard brake gestures
If the habit of squeezing the right hand with one hand and one hand has been developed, and there is no need to be nervous, daily commuting is gradually corrected by simple means:
1. Commencement by default of the left hand on the rear brake handle, with the first reaction of daily deceleration squeezing the left brake as the normal main brake
2. Exercise of emergency brakes in empty unmanned sections: 25 km/h flat speed, exercise of the "left-to-right" brake rhythm to form muscle memory
3. The right-hand front brakes are used only as auxiliary support and only if they are required to stop at the shortest distance, they are used slowly, and the right front brakes are never squeezed separately。
A small practical check was added: a simple test of brakes before a monthly trip, the smoothness of the handles, the heavy wear and tear of brake blades, and the relevance of brake safety and daily riding experience。
Vii. Common rumours to dispel unnecessary concerns
Zone of error 1: the electric car has abs to hold to death, and the brakes will not slide。
At present, there is only a medium-high-end power-motion base abs, and the vast majority of the new state-of-the-art electric cars are not equipped with a death-proof system, and the front wheel will still die and cannot rely on electronic configuration to relax brakes。
The front brakes should be used more when carrying man loads。
The load is then moved back to the centre of gravity, the back-wheel grip is increased, the human scene is given priority over the rear brake, which needs to be softer to prevent the forward movement of the centre of gravity。
Mistake 3: old money is not subject to electric brake layout and the new standard is the opposite。
Very few old car-type configurations differ from one another in the early years, the simplest of which is the prosecution's method: holding up, squeezing the brakes, observing which wheel is locked before and after, confirming its own brake layout, then applying the standard technique。
Summary of text
For many years, motor vehicles have been riding, most people have been in error, and the core is unclear about the unified layout of the national sign: left-hand brakes control the rear wheel (stabilizing the main force) and right-hand brakes control the front wheel (power-assisted). The simple logic of using the left-hand backbrake for daily smoothing of parking tickets, the urgent brakeing of the sequence, a lighter front brake, and a lower slope and less front-brakes in the rainy season avoids the risk that most electric brakes will run out of control。
The safety of the vehicle is never a matter of the cost of the vehicle, but of the scientific nature of the routine car usage. Without complex and hard-to-understood expertise and simply reprioritizing the right and right brakes, riding stability can be significantly enhanced, vehicle spare parts protected and daily commuting made less costly and safer. The essence of digital step-by-step hardware is to serve life and rationally master practical and operational skills。
