1. axle suspension
non-independent suspension and is relatively independent suspension (individual wheel suspension) of the wheel structure.
Structural features of non-independent suspension of each wheel is connected by an integral frame, the wheel together with the axle is suspended by the elastic suspension of a vehicle body frame or below. Axle suspension has a simple structure, low cost, high strength, easy maintenance, small changes in wheel alignment in road advantages, but because of its comfort and steering stability are poor, substantially no longer used in modern passenger cars , the use in trucks and buses. .
a non-independent suspension type and characteristics:
non-independent suspension each wheel is mounted on an integral axle, the axle is connected to the frame through the suspension . This suspension structure is simple, reliable power transmission, but when the two affect each other by shock and vibration. And due to the poor quality heavy unsprung suspension cushioning performance, vehicle vibration during traveling, greater impact. The suspension is generally used for trucks, buses and other ordinary vehicles.
1) steel spring axle suspension
an elastic leaf spring member is used as a non-independent suspension, and since it acts as a guide means, such that the suspension system is greatly simplified . This suspension is widely used before the truck, the rear suspension. The middle leaf spring which is fixed to the axle with a U-bolt. Suspension front end fixed hinge, also known as dead lug. It is connected to the pin by a leaf spring leaf spring eye portion distal front bracket together with the leaf spring, the front end of the ear hole to reduce the volume with wear liner. The rear end of the ear by the leaf spring pin connected to the rear end of the lug and lug lug carrier, the rear end can swing freely, forming the movable lug. When the carriage impact spring deflection distance between two possible changes of the Word.
2) of the coil spring axle suspension
Since the coil spring as the elastic member, can only withstand vertical loads, soWhich suspension system is provided to add and the damper guide.
3) Air spring axle suspension
cars during travel due to changes in load and the road surface, suspension stiffness requirements vary. When the vehicle body is raised when empty, were low for the body when fully loaded, the buffer block where the impact occurs. Therefore proposed for different requirements of different types of automobile, mining and large passenger vehicle requirements when it is not empty and full height variation; for the car to lower the ride height in a good way, to improve the speed limits; enhance the body in a bad way, you can increase large capacity. Thus requiring ride height can be adjusted with the use requirements.
