Bidirectional vibration absorption type rear suspension device of driving cab of automobile

Abstract

A bidirectional vibration absorption type rear suspension device of a driving cab of an automobile comprises a left mechanism and a right mechanism. The left mechanism and the right mechanism are bilaterally symmetric, structures of the left mechanism and the right mechanism are consistent, the left mechanism is connected with the right mechanism by oil tubes and a crossbeam, both the left mechanism and the right mechanism consist of upper connecting supports, middle connecting plates and lower connecting supports, upper portions of the upper connecting supports are fixedly connected with the driving cab, lower portions of the upper connecting supports are movably connected with hydraulic locks, lower portions of the hydraulic locks are fixedly connected with the middle connecting plates by top connecting holes, side connecting holes on the middle connecting plates are hinged with transverse vibration absorbers, the other end of each transverse vibration absorber is hinged with the corresponding lower connecting support, and the oil tubes are connected onto the hydraulic locks. The lateral buffering performance of the bidirectional vibration absorption type rear suspension device is better, movement discordance can be avoided, and smoothness, safety and comfortableness of the driving cab can be improved.

Description

technical field [0001] The invention relates to a rear suspension device of an automobile cab, in particular to a two-way damping rear suspension device of an automobile cab, which is particularly suitable for attenuating the impact of various roads on the cab in the vertical and lateral directions. Background technique [0002] The rear suspension device of the automobile cab is a device that connects the cab and the frame in a floating manner. It has a good damping function and can attenuate the vibration transmitted from the frame to the cab. The traditional rear suspension of the cab is only equipped with shock absorbers in the vertical direction, and the connecting plate or tie rod with rubber bushing is generally used as the guiding and restraining element in the lateral direction. This type of rear suspension can only control the vibration in the vertical direction. It plays a damping role, but cannot effectively dampen lateral vibrations. [0003] The Chinese patent...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the defects and problems in the prior art that the lateral cushioning performance is poor, which will damage the ride comfort and safety of the driver's cab, and cause uncoordinated movement, and provide a lateral cushioning performance Good, will not damage the ride comfort and safety of the cab, and will not produce uncoordinated movement of the two-way vibration-absorbing rear suspension of the car cab
