A commercial vehicle cab suspension assembly

Abstract

A suspension assembly for a cab of a commercial vehicle, comprising a frame bottom plate, the top surfaces of two square boxes with open top surfaces are respectively fixedly connected to the two sides of the bottom surface of the frame bottom plate, and the inner walls and bottom surfaces of the square boxes are respectively provided with through holes and through holes There are two connecting rods that are in sliding contact with each other. The lower ends of the two connecting rods are fixedly connected to the upper ends of the shock absorbers with hard springs, and the lower ends of the other two connecting rods are respectively fixedly connected with soft springs. The upper end of the shock absorber of the spring and the upper end of the connecting rod are respectively fixedly connected to the bottom surface of the square plate, and the square plate is in sliding contact with the corresponding square box respectively. The device can adjust the height of the frame bottom plate, thereby preventing the frame bottom plate from colliding, or reducing the wind resistance of the vehicle. Again, the device can replace the shock absorber during the running of the vehicle, and is easy to use.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a commercial vehicle cab suspension assembly. Background technique [0002] The coefficient of elasticity of the shock absorbing springs used in existing automobiles cannot be adjusted. When using soft springs, the coefficient of elasticity of the soft springs is relatively low, and the shock absorption effect is relatively good. During the operation of the road), the car is not stable enough. When the hard spring is selected, the elastic coefficient of the hard spring is relatively high, and the shock absorption effect is relatively poor. When running on an unstable road (such as a dirt road), the comfort of passengers poor. Contents of the invention [0003] The invention provides a commercial vehicle cab suspension assembly to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A suspension...
