Steering damper

Abstract

The invention discloses a steering damper. The steering damper comprises a working cylinder and a piston rod, wherein an inner chamber of the working cylinder is filled with oil; the piston rod moves in the axial direction of the working cylinder; the outer end of the piston rod extends out of one end of the working cylinder; oil seal covers are mounted at the two ends of the working cylinder; an oil storage cylinder is arranged on the outer side wall of the working cylinder and communicated with the working cylinder; a resetting valve assembly is mounted at the end part, positioned in the working cylinder, of the piston rod; a first spring seat is arranged at the other end of the oil storage cylinder, and a second spring seat is arranged at the outer end of the piston rod; a damping spring is arranged between the first spring seat and the second spring seat. External impact energy on a steering machine can be rapidly absorbed through the additionally-arranged damping spring, and the energy absorbed through the damping spring can be rapidly converted into heat under the action of the piston rod in the working cylinder, a working medium and the oil storage cylinder, so as to achieve rapid elimination of vibration of the steering machine, and avoid the problem of potential safety hazards of a steering wheel, which are caused by the vibration of the steering machine.

Description

technical field [0001] The invention relates to a driving safety device for a steering gear, in particular to a steering shock absorber. Background technique [0002] The steering shock absorber is used to reduce the vibration of the steering mechanism and change the natural frequency of the steering mechanism when the driver turns the steering wheel, so as to reduce the wear of the steering mechanism and increase the service life of the steering mechanism. When the car is moving forward and encounters an uneven road surface, when the car vibrates, the steering mechanism will also vibrate together, and the corresponding connecting parts will vibrate at a high frequency, and the friction and wear will increase. [0003] In order to improve the service life of the steering mechanism, a double-cylinder shock absorber connected with the steering gear is installed at the steering gear in the prior art. Since the steering gear is in a horizontal position when it works, the working...

AI Technical Summary

Problems solved by technology

[0004] When the steering gear vibrates, it takes a long time to release the absorbed energy through the piston rod moving and compressing the working medium; and the working medium entering the airbag needs a lot of pressure to flow back into the working cylinder. If the pressure is not enough, it will be difficult for the working medium to flow back into the working cylinder, making it difficult to reset the piston rod, which will seriously affect the shock absorption of the shock absorber after long-term use
