Rubber spring, rubber suspension system and cargo truck

Abstract

The invention discloses a rubber spring. The rubber spring comprises a first mounting plate, a second mounting plate, and multiple rubber layers, wherein the first mounting plate is provided with a first V-shaped plate with an opening angle greater than 90 degrees; the second mounting plate is provided with a second V-shaped plate with the opening angle greater than 90 degrees; the multiple rubber layers are arranged between the first V-shaped plate and the second V-shaped plate; each two adjacent rubber layers are separated by an intermediate plate; the intermediate plate is a V-shaped plate with the opening angle greater than 90 degrees; and the opening directions of the first V-shaped plate, the second mounting plate and the intermediate plate are the same. The rubber spring has a certain transverse stiffness while enabling a suspension to satisfy the requirements for lengthways and vertical bearing capabilities; the transverse stiffness can be up to 3-15 kN / mm through the adjustment of the hardness of a sizing material of a rubber layer 202; when a vehicle turns a corner or runs on a concave-convex road surface, the rubber spring can bear a very great transverse force to reduce yaw of the vehicle and improve transverse stability of the whole vehicle. The invention also discloses a rubber suspension system and a cargo truck.

Description

technical field [0001] The invention relates to the technical field of suspension, and more specifically, relates to a rubber spring, a rubber suspension system and a truck. Background technique [0002] The rubber suspension is a new type of suspension system. Because the rubber itself has the characteristics of large deformation and variable stiffness, the rubber suspension has excellent bearing capacity, and it can provide good stability for the whole vehicle as the load changes. smoothness. The rubber suspension is easy to install, easy to load and disassemble; it has the characteristics of no lubrication and no maintenance; more importantly, the self-weight of the rubber suspension is lighter than that of the traditional leaf spring suspension, which is in line with the development trend of vehicle lightweight and has good fuel efficiency. Economical, rubber suspensions have been widely used on road vehicles and off-road vehicles. [0003] In the existing rubber suspe...

Problems solved by technology

[0004] However, because not all vehicles are suitable for road conditions and load control, when the form of the vehicle is not suitable for road conditions and load control, this kind of rubber suspension with straight rubber springs and thrust rods arranged longitudinally is suitable for use. During the process, since the lateral stiffness of the straight rubber spring is very small, generally below 1kN / mm, when the vehicle is turning or driving on uneven roads, the vehicle will yaw due to the absence of a special lateral limiting device. , even rollover

[0005] In order to improve the above problems, V-shaped thrust rods can be used, but the use of V-shaped thrust rods will require more layout space, and when the road conditions are bad, the service life of the thrust rods will be greatly reduced
