Automobile cab rear air spring U-shaped support structure

Abstract

An automobile cab rear air spring U-shaped support structure comprises a longitudinal beam, a bottom plate is arranged on the top surface of the longitudinal beam, the bottom plate is rotatably connected with the longitudinal beam through a plurality of hinges arranged on the front side of the longitudinal beam, a hinge seat is fixedly installed on one side of the top surface of the bottom plate,and a first sliding groove is transversely formed in the other side of the top surface of the bottom plate; the side, close to the middle of the bottom plate, in the first sliding groove is fixedly connected with one end of a spring, the other end of the spring is fixedly connected with a first sliding block, a hinge base is fixedly installed on the top face of the first sliding block, a shear fork connecting rod is arranged above the bottom plate, and the two ends of the lower portion of the shear fork connecting rod are hinged to corresponding hinge bases on the bottom plate. While a cab isreliably supported and damped, on the one hand, the safety guardrail effect can be achieved when the cab is turned over, on the other hand, the cab can be used as an operation platform in the overhauling process, the problem that a user has no place to stand when overhauling a truck engine compartment is solved, and operation safety and work efficiency are improved.

Description

technical field [0001] The invention belongs to the field of automobile chassis production, in particular to a U-shaped bracket structure of an air spring behind an automobile cab. Background technique [0002] In order to facilitate inspection and maintenance, the cab of the truck mostly adopts a reversible design. The front bracket connecting the cab and the longitudinal beam is a hinged structure, and the rear bracket is a detachable U-shaped bracket support structure. With the continuous improvement of users' requirements for driving comfort, the rear brackets of trucks have also been upgraded from rigid brackets and semi-flexible brackets to the most advanced air spring flexible brackets, but the existing rear brackets are mostly for the rear of the cab. Two-point support, less support points, long-term driving in bad road conditions may easily cause cab deformation; in order to ensure safety, automobile manufacturers require that the cab must be completely flipped open...

Problems solved by technology

[0002] In order to facilitate inspection and maintenance, the cab of the truck mostly adopts a reversible design. The front bracket connecting the cab and the longitudinal beam is a hinged structure, and the rear bracket is a detachable U-shaped bracket support structure. With the continuous improvement of users' requirements for driving comfort, the rear brackets of trucks have also been upgraded from rigid brackets and semi-flexible brackets to the most advanced air spring flexible brackets, but the existing rear brackets are mostly for the rear of the cab. Two-point support, less support points, long-term driving in bad road conditions may easily cause cab deformation; in order to ensure safety, automobile manufacturers require that the cab must be completely flipped open and locked before personnel can enter the engine compartment under the cab. Inspection and maintenance, but in actual use, people often enter the engine compartment without waiting for the cab to be flipped in place in order to save time, which poses a relatively large safety hazard; It is often necessary to climb up and down on the front wheels, which will cause serious safety hazards while dirtying clothes and consuming physical strength
