Suspension structure with transverse composite leaf spring

Abstract

The invention relates to a suspension structure with a transverse composite leaf spring. The suspension structure comprises vehicle axle connection structures respectively arranged at two sides below a main vehicle frame, wherein the two vehicle axle connection structures are used for connecting a vehicle axle with the main vehicle frame; the longitudinal direction of the two vehicle axle connection structures is arranged in parallel with the longitudinal direction of the main vehicle frame; shock absorption structures are arranged between the two vehicle axle connection structures and the main vehicle frame; and a transverse composite leaf spring structure capable of expanding and contracting in the transverse direction of the main vehicle frame and being connected with the main vehicle frame is arranged between the opposite ends of the two vehicle axle connection structures. The suspension structure with the transverse composite leaf spring overcomes the problem that the longitudinal installation of the leaf spring in the suspension structure is limited by the space of a chassis in the prior art and the problems of high cost, short service life, hidden dangers and the like of air springs in the prior art, and has the advantages of making full use of light weight, good energy absorption capacity and other characteristics of the composite leaf spring, occupying little space on the chassis, increasing service life, effectively reducing the cost and improving the safety.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension systems, in particular to a suspension structure of a transverse composite material leaf spring. Background technique [0002] Automobile suspension system (also known as automobile suspension system) is a general term for all force transmission connection devices between the frame and axle or wheels of the automobile. Its function is to transmit the force and moment acting between the frame and the wheels, and Buffer the impact force transmitted from the uneven road to the frame or body, and attenuate the resulting vibration to ensure the smooth running of the car. The automobile suspension system mainly includes three parts, which are elastic elements (elements that bear and transmit vertical loads in the suspension system and have the ability to ease and suppress the impact caused by the road surface), shock absorbers and guide mechanisms. [0003] At present, elastic components mai...
