A cab rear support structure

A support structure and rear support technology, which is applied to the upper structure, upper structure of trucks, transportation and packaging, etc., can solve the interference of ship-shaped brackets, poor low-frequency and high-frequency vibration vibration isolation, and easy to be affected by the outside of the frame. The impact of tension and other problems can solve the problem of shock absorption and noise reduction, good damping limits low-frequency large-scale vibration, and eliminates the effect of dynamic hardening.

Problems solved by technology

[0003] Due to the separation of the left and right rear supports, the distance between the left and right rear supports is easily affected by the stretching of the frame, resulting in interference between the cab and the boat bracket
The traditional car cab rubber pad suspension is not good for low-frequency and high-frequency vibration isolation

Abstract

The invention provides a rear supporting structure of a cab. The rear supporting structure comprises a pipe beam support, a rubber mat supporting frame, a rubber mat and a small boat support. The pipe beam support comprises a U-shaped pipe and base leg supports, and the base leg supports are fixed at two ends of the U-shaped pipe to have a supporting effect. The rubber mat supporting frame comprises a circular pipe and a supporting frame. One end of the supporting frame is fixedly connected with the circular pipe, and the other end of the supporting frame is fixedly connected with the base leg supports. The rubber mat is fixed on the circular pipe. The small boat support is fixed on the rubber mat. The rear supporting structure adopts a whole pipe beam structure and guarantees that a gap between a left rear support and a right rear support is not affected by vehicle frame extension. The rear supporting structure provides a new suspension liquid charging rubber mat to replace a traditional suspension rubber mat of an automobile cab and achieves shock absorption and noise reducing of the automobile cab. Low-frequency large amplitude vibration of the cab can be effectively restrained by using the liquid charging rubber mat. Simultaneously high-frequency noise in the cab is removed, and riding comfortableness of an automobile is improved.

Description

technical field [0001] The invention belongs to the rear support structure of a light truck cab, in particular to a novel cab rear support structure with a liquid-filled rubber pad. Background technique [0002] At present, the rear support mechanism of the light truck cab basically adopts the form of left and right separation. The left and right rear supports are independent of each other and are respectively fixed on the left and right longitudinal beams of the vehicle frame. The cab is suspended by the traditional automotive cab rubber pad on the rear support to achieve vibration reduction. [0003] Due to the separation of the left and right rear supports, the distance between the left and right rear supports is easily affected by the stretching of the frame, resulting in interference between the cab and the boat-shaped bracket. Traditional automotive cab rubber pad mounts are not effective in isolating low-frequency and high-frequency vibrations. Contents of the inve...
