Problems solved by technology

[0002] At present, trucks in our country generally adopt two structures of leaf spring suspension and air suspension. Although the price of leaf spring is relatively cheap, there is no change in stiffness and it is easy to be damaged. Although the structure of air suspension is more comfortable than that of leaf spring, the structure is complicated.
During the driving process of these two structures, the "swaying" of the vehicle is more serious.

Abstract

The invention discloses a rubber vehicle suspension device with variable rigidity property, which is characterized in that a vehicle frame is fixedly connected with a cross beam, a connection bracket is arranged on the vehicle frame, one end of a V-shaped thrusting rod is fixed on the vehicle frame and the other end thereof is fixed at the upper end of an axle through a thrusting rod pedestal, one end of a multi-layer rubber nonprismatic bumper block is fixed at the bottom end of the connection bracket, the other end thereof is suspended over the top end of a rubber spring bracket, the rubber spring bracket is fixed on a lug support by a bolt, both ends of the lug support are respectively connected with an axle pedestal which is fixed on the axle. By the above setting, the rubber vehicle suspension device with variable rigidity property has large bearing capacity, low frequency of vibration in the situation of idle load and full load, and small lateral oscillation of vehicle.

Description

technical field [0001] The invention relates to a vehicle suspension device with variable stiffness performance. More precisely rubber suspensions for commercial vehicles. Background technique [0002] At present, trucks in my country generally adopt two structures: leaf spring suspension and air suspension. Although the price of leaf spring is relatively cheap, there is no change in stiffness and it is easy to be damaged. Although the structure of air suspension is more comfortable than that of leaf spring, its structure is complicated. The "swaying" of the vehicle during the driving of these two structures is more serious. In recent years, with the rapid development of road construction in my country, the increase of logistics volume and the rise of fuel prices, users have put forward higher requirements for the economy, comfort and reliability of freight vehicles. Contents of the invention [0003] The object of the present invention is to provide a suspension system ...
