The effect that frame structure, arrangement are not quite similar, but are completed is identical, the i.e. power of transmitting power device to wheel, then general
The torque for being transmitted to wheel is converted into the thrust in face, ground over the ground and gives wheel one reaction force again --- and tractive force finally will
Tractive force is transmitted to the various pieces of automobile, to guarantee the normally travel of vehicle；Change or restore the driving direction of automobile；It allows
Car deceleration or parking allow the vehicle of stopping to remain stationary.
The general cost of the mode of active accommodation vehicle chassis height is high in the prior art, is applied to luxurious commercial vehicle more.
Based on agri-vehicle user's economic situation, the chassis length and height of existing agri-vehicle are generally fixation, cannot be adjusted, this
Affect the passage capacity of vehicle, cause vehicle mobility decline, when traveling it is rough and uneven in surface or zig zag road surface when, bottom
Disk be easy with ground face contact and so that chassis part collided with, scratched or cornering difficulties, when traveling in smooth-riding surface when cannot drop
Low chassis will increase resistance；On the other hand, most of agricultural vehicle use front-wheel or rear wheel drive, when driving wheel occur obstacle or
Power is just lost when aerial, it is inflexible.So some needs are travelled on complicated and changeable, road conditions bad road, or
There is the vehicle of particular/special requirement, the construction on the chassis that is still further improved.
