Abstract

The invention discloses a suspension device for a heavy-duty truck cab, relating to the technical field of truck manufacturing. The suspension device comprises a front suspension device and a rear suspension device, wherein the front suspension device comprises a front suspending stabilizer bar, front suspending vibration dampers and helical springs; the rear suspension device comprises rear suspending vibration dampers, a rear suspending arched beam and a rear suspending floating beam; the rear suspending vibration dampers are air spring vibration dampers; the two ends of the rear suspending vibration dampers are respectively hinged on the lower parts of hydraulic lock installation plates and rear suspending vibration damper installation plates vertically; and a rear suspending tie bar is installed between the hydraulic lock installation plates and the rear suspending arched beam. Compared with the prior art, the suspension device can solve the problems of poor comfort, insufficient stability and poorer operation safety of the truck cab.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a suspension device for a cab of a truck. Background technique [0002] When the car is running, the vibration on the cab is mainly transmitted to the cab by the road surface through the chassis suspension, engine suspension, and cab suspension system. The body and the frame of the traditional automobile cab are connected by ordinary vibration damping and direct connection. At present, most of the cabs of major domestic truck products adopt the suspension system with rubber materials as the suspension components. This structure has certain effects on the vibration transmitted to the cab when the vehicle is running at a low speed on a flat road. Barrier and relief. However, when the vehicle is running at a high speed or on a road with poorer road conditions, the rubber suspension cannot well attenuate the vibration, the structural vibration in the cab and the vi...
