Abstract

The invention belongs to the field of commercial vehicle bodies, and relates to a vehicle hydraulic cylinder rear-tilting-type mechanical floating assembly. The mechanical floating assembly comprisesa bracket assembly, a swing arm assembly and a hydraulic cylinder assembly and is characterized in that the bracket assembly is rotatably connected with the swing arm assembly, and the swing arm assembly is rotatably connected with the hydraulic cylinder assembly. The vehicle hydraulic cylinder rear-tilting-type mechanical floating assembly has the advantages that the problem of up-down bouncing of a cab when a vehicle is driven is solved through the movement of a swing arm, the problem of repeated swinging when the cab turns over can be solved through the arrangement of a rear-tilting-type hydraulic cylinder, and a hydraulic cylinder turns over cross the center of gravity of the cab and is limited. Thus, the service life of the hydraulic cylinder is prolonged, the damage rate is reduced,and the safety is improved.

Description

technical field [0001] The invention relates to a vehicle hydraulic cylinder backward tilting mechanical floating assembly assembly, which belongs to the field of commercial vehicle bodies. Background technique [0002] At present, the cab tilting of medium and heavy commercial vehicles is mainly based on hydraulic tilting, which has the advantages of large supporting force and high reliability. When the vehicle is running normally, the cab will jump up and down according to the different road excitations. Therefore, the hydraulic cylinder in the hydraulic system needs to be extended or shortened at any time with the movement of the cab so as not to damage the floor beam of the cab. Most of the medium and heavy commercial vehicles on the market now use hydraulic hydraulic cylinders to solve the problem of cab jumping up and down. However, in the case of bad road conditions, the frequent bumping of the cab will greatly shorten the service life of the hydraulic cylinder or dam...
