1. Composition:
The engine is powered in sequence through the clutches, the transmissions, the all-way transmission devices, and the main brakes, the differentials and the semi-axis installed in the drive bridge。
2. Function:
The basic function of the car moving system is to transfer the power from the engine to the wheel。
The primary task of the motor system is to work with engines to ensure that cars can travel normally under different conditions of use and are highly dynamic and fuel-economic。
To this end, any type of kinetic system must have the following functions:
(1) decreasing increment
Reduce the turn speed of the wheel and, accordingly, increase the turnback of the wheel。
The minimum value of the motion transfer ratio imin shall ensure that the vehicle can overcome the rolling on a smooth and good road。
Resistance and air resistance and travel at the corresponding maximum speed。
Ilin: car, light, minivan: 3-6
Truck, medium, heavy: 6-15
The minimum transmission ratio is achieved through the main speed-retarder。
The maximum imax of the motion transfer ratio shall ensure that the vehicle's pull is sufficient to overcome the maximum resistance and to drive at a stable speed。
Imax: sedan: 12-18
Truck, light, medium and heavy: 35150
The maximum transmission ratio is achieved through a combination of speed transformers and a pre-speed-depressor and breast-milk placement programme。
The transmission of the transformer is expressed in ig。
(2) rate changer
In order to keep the engine within a favourable rate of rotation, which can be changed within a sufficiently large range by the vapour pull and velocity, the drive-moment ratio should change between the maximum and the minimum, i. E., the rate of transformation。
The total motion ratio of the moving system is equal to the rater and the main speed-retarder drive multiplier, i=igxio。
There's a class rate change: the moving ratio is limited。
The average sedan and light and medium-sized trucks have a three-to-five transmission ratio。
Cross-country vehicles and heavy vehicles can move as much as 8-10。
No class rate: the movement ratio is continuous and gradual。
(3) a reverse car
The vehicle needs to be rewinded and rewinded in the transmission。
(4) interruption of transmission if necessary
Start engine; transmission slot。
When the car starts; manipulate the clutch, speed transformer forward。
Switching; manipulating the clutch, retrofitting。
Brake while; separating the clutch。
Long stop times; transmission slots。
Long distance slide。
(5) speed difference
The bridge is equipped with differentials that allow the right and right two-drives to rotate at different angle speeds。
The power is transferred from the main brake to the differential, which is then assigned to the right and right two-and-a-half axes, and finally to the driver on both sides。
(6) trend
To address the adverse effects of relative movement between the transformer and the driver bridge, a one-way transmission device consisting of a one-way verse and axle is used。
