Description
Technical Field
The utility model belongs to the technical field of automobile parts, concretely relates to car leaf spring suspension.
Background
The suspension system is an important component of the automobile, and the quality of the suspension system directly influences the smoothness, the controllability, the reliability and the like of the whole automobile. The existing automobile has many types of suspensions, and all suspension systems can be divided into two main types, namely an independent suspension and a non-independent suspension according to a guide element, wherein the non-independent suspension of the steel plate spring is one of the non-independent suspensions. The steel plate spring suspension has the advantages of small tire positioning parameter change, simple and reliable structure, few easily-damaged parts, low maintenance and repair cost and the like, so that the steel plate spring suspension is widely applied to the rear suspension of the commercial vehicle upper suspension system and partial low-end passenger vehicles.
Through retrieval, the Chinese utility model patent with application number 201720027004.8 discloses an automobile leaf spring suspension, in the scheme, a horse riding bolt is fixed in the middle of a leaf spring, a bottom plate is arranged on the bottom surface of the leaf spring, and a fixing bolt penetrates through connecting holes of the bottom plate and the leaf spring to perform central limiting on the leaf spring, wherein the middle of the leaf spring is planar; or the automobile steel plate spring suspension comprises: a pressure plate and an elastic body. The first scheme is as follows: the middle part of the steel plate spring is processed into a plane shape, so that the arc height change of a clamping section of the steel plate spring can be reduced, the clamping force of the riding bolt is reduced, the torque is tightened, and the looseness of the riding bolt is avoided. Scheme II: the elastic body is added between the pressing plate and the steel plate spring, and the gap between the pressing plate and the steel plate spring can be filled due to the existence of the elastic body, so that the pressing plate is ensured to be a plane, and the clamping force and the tightening force required for fastening the riding bolt are reduced; when the steel plate spring works, the arc height change of the clamping section of the horsebolt is compensated by the elastic body, the clamping force of the horsebolt is not influenced, and the horsebolt can be prevented from loosening.
