Steerable hydro-pneumatic spring

Abstract

The invention relates to a hydro-pneumatic spring for a vehicle suspension, in particular to a steerable hydro-pneumatic spring which comprises an oil inlet joint, a steering arm, a guide cylinder, a piston rod cover, a piston, a cylinder barrel guider, a cylinder barrel, a spline shaft, a cylinder barrel bottom cover and a limit block. The oil inlet joint is arranged at the upper end of the piston rod cover, the steering arm is connected on the piston rod cover through a spline, the piston rod cover is fixedly connected at the upper end of the piston in a welded manner, the spline shaft is connected with the piston and the cylinder barrel bottom cover through splines, the cylinder barrel with the cylinder barrel guider is connected with the cylinder barrel bottom cover in a threaded manner, a guide mechanism comprises the guide cylinder with a connection seat and the cylinder barrel with the cylinder barrel guider, the guide cylinder with the connection seat is fixedly connected with a frame A2, movement of the steering arm cannot be interfered by vertical jumping of a wheel A8, the cylinder barrel bottom cover is connected with the wheel A8, and torque generated by the steering arm is transmitted to the cylinder barrel bottom cover through the piston rod cover, the piston and the spline shaft 8, so that steering of the wheel A8 is realized.

Description

technical field [0001] The invention relates to an oil-pneumatic spring for vehicle suspension, in particular to a steerable oil-pneumatic spring, which is suitable for application on large vehicles such as off-road vehicles and engineering vehicles. Background technique [0002] The hydropneumatic springs used in common vehicles provide elasticity and damping, and may also have a function of height control. Usually another guide system is required to achieve the correct relative movement between the wheels and the body. [0003] The oil-pneumatic spring installed on the steering wheel must be separately installed to realize the steering system of the wheel, which often brings problems such as complex structure, difficult layout, and increased manufacturing cost. In some vehicles with more steering wheels and longer wheelbase, this arrangement is almost impossible to realize. At the same time, the installation of the steering system will also have a negative impact on the ...

AI Technical Summary

Problems solved by technology

[0003] The oil-pneumatic spring installed on the steering wheel must be separately installed to realize the steering system of the wheel, which often brings problems such as complex structure, difficult layout, and increased manufacturing cost.

In some vehicles with many steering wheels and long wheelbase, this arrangement is almost impossible to realize

At the same time, the installation of the steering system will also have a negative impact on the design of the vehicle's load-carrying space; when the wheels of a vehicle with a steering system generally jump, some parts of the steering system will jump along with it, causing interference, thereby forming an undesirable phenomenon of additional steering angle
