U-shaped bracket structure of air spring rear of automobile cab

Abstract

A rear air spring U-shaped bracket structure of an automobile cab, including a longitudinal beam, a bottom plate is arranged on the top surface of the longitudinal beam, and the bottom plate and the longitudinal beam are rotatably connected by several hinges arranged on the front side of the longitudinal beam, and one side of the top surface of the bottom plate The hinged seat is fixedly installed, and the other side of the top surface of the base plate is provided with a first chute horizontally, and the first slide block is slidably fitted in the first chute, and one end of the spring is fixedly connected to the inside of the first chute close to the middle side of the base plate , the other end of the spring is fixedly connected with the first slider, the top surface of the first slider is fixedly installed with a hinged seat, a scissor link is arranged above the bottom plate, and the lower ends of the scissor link are respectively connected with the corresponding hinged seat on the bottom plate Articulated connections. While reliably supporting and damping the cab, the present invention can play the role of a safety guardrail when the cab is overturned on the one hand, and can be used as a work platform during the maintenance process on the other hand, which solves the problem that the user needs to repair the engine compartment of the truck. When there is nowhere to stand on the problem, the 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...

AI Technical Summary

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
