Prior to 1898, engine power output was passed directly through gear to the drive axis, thus limiting the location of the engine to the drive axis, making design of the vehicle difficult. It is thanks to the all-wide invention that today's pre-post-drive, pre-drive cars, mark the maturity of motor mobility technology。
The main functions of the car moving system are as follows:
Collar
Function:
1 the clutch allows for the gradual integration of motors with transmission systems and ensures a smooth start。
2. The clutch may temporarily cut the connection between the engine and the transmission system and facilitate the start-up of the engine and the switch-off of the transformer to ensure smooth work during the transfer。
3 the clutch also limits the transects passed and prevents the transferal overload。
Composition: active, aerodynamic, compacting, separation and manipulation。
Speed transformer
Function:
One, achieve speed change。
Two, reverse the car。
3. Interruption of power transmission if necessary。
4. Achieve power output。
Since transformers are classified in various forms, such as mt, at, amt, dct, cvt, manual and automatic, manual transformers are most common and automatic transformers are more common and tend to replace manual transformers. Although different types and components vary. But the function is almost the same. It is clear that the atm structure is more complex, more technical, simpler to operate, more expensive and less easy to repair. Requirements for transformers:
1 prevents automatic switch-off and break-out of transformers。
2 to ensure that transmissions are not carried to both slots at the same time。
3 to prevent the misdirection。
All-way transmission
Function: transmit power between any of the inter-axis angles on the vehicle and the revolving axis where the relative position changes frequently。
1. Between the transformer (or splitr) and the driver bridge
In general, the output axis of fr and the input axis of the drive bridge are difficult to re-engineer, and the beating of the vehicle during the change in load and during the run-off will change the angle and distance between the drive-in axis and the transmission axis, so that the all-way transmission unit is connected。
2. Between a transformer and a clutch or a splitr
While transmissions are supported by transformers, clutches, splitrs, etc., and their axes can also be designed to overlap, they are often accompanied by all-way transmission devices designed to eliminate the effects on power transmission of axle coaxial error caused, for example, by deformation of the frame and error in manufacture, assembly, etc。
3. Turn and break-dry bridges medium
The vehicle's turn-drive requires a shift-and-drive function, half-axis of which the half-axis are in segments, and two segments of the half-axis are interlocking and interlocking, so that the all-way transmission device is used. In a break-drive bridge, the main speed-retarder shell is fixed on the frame of the vehicle, with a swinging up and down of the bridge shell, with a half-axis in fractions, and a all-way transmission device。
4. Turning to manipulation medium
Some vehicles are subject to overall set-up restrictions, the steering axle does not overlap with the input axle of the wheel, and therefore are equipped with all-way transmission devices in the steering axle
Drive bridge
The power that drives the bridge conveys from a universal transmission device (or a transformer) is sharpened at speeds and changes the direction of the power transfer. After the engine has been set up, the vehicle is assigned to the left and right wheel, which is allowed to rotate at different rotation speeds。
The bridge is the last sum of the moving system, which consists of the main brake, the differential, the half-axis and the bridge shell。
1 the main decelerator increases the input rectangular, reduces the rotation speed and transmits the power transfer direction (except for engines) to the differential。
2 the function of the differential is to transfer the power from the main brake to the left, to the right, and, if necessary, to allow the left, to the right, to be rotated at different rates to meet the need for a side-drive-drive。
Three, half-axis are used to transfer power from the differential to the driver。
4 the driving bridge housing is both part of the moving system and part of the driving system, which is designed to install and protect the main brakes, speed differentials and half-axis, as well as to install suspensions or wheels. It is also required to support parts of the vehicle's suspension above the bridge, to withstand the reaction and force rectangles from the driving wheel and to pass between the wheel and the suspension。
