Abstract

A plate spring and steering knuckle connection bracket applicable to an inclined plate spring suspension comprises a connection bracket part, wherein one side of the connection bracket part is connected with a steering knuckle; the other side of the connection bracket part is connected with a plate spring; the connection bracket part comprises a plate spring fixing frame, a steering knuckle connecting shaft and a shock absorb er mounting shaft; one side of the plate spring fixing frame is irrationally matched with one end of the plate spring via the plate spring fixing shaft; the other side of the plate spring fixing frame is connected with the steering knuckle connecting shaft; and the shock absorb er mounting shaft is arranged at the bottom of the plate spring fixing frame. The plate spring and steering knuckle connection bracket has an excellent load carrying property and high reliability, and furthermore, the service life of the plate spring can be prolonged.

Description

technical field [0001] The invention relates to an automobile leaf spring connecting bracket, in particular to a leaf spring and steering knuckle connecting bracket suitable for an inclined leaf spring suspension, and is particularly suitable for improving the bearing capacity of the suspension and optimizing the force performance of the leaf spring. Background technique [0002] At present, the front axle of commercial vehicles generally adopts leaf spring non-independent suspension, and matches the trapezoidal steering mechanism, in which the steering knuckles on both sides are connected by rigid axles, and the leaf springs are fixed to the axles. The leaf spring non-independent suspension has the advantages of simple structure and low cost. However, due to the mutual influence of the wheels on both sides and the large friction between the leaf spring pieces, the handling stability and ride comfort of the vehicle are poor. Independent suspensions can overcome the above-men...
