Self-return type power-assisted steering tube

Abstract

The invention discloses a self-return type power-assisted steering pipe. The invention belongs to the field of automobile hydraulic steering equipment. The invention discloses a self-return type power-assisted steering tube. The selective positioning bending ring can be embedded into the framework layer, the selective positioning bending ring selectively bends at the part of the outward bending ring; on one hand, the outward elastic force provided by the bending point is obviously increased; on the other hand, the bending direction of the bending point is inward, therefore, the power-assistedsteering tube cannot be flattened or is difficult to flatten; therefore, the probability that the power-assisted steering tube is bent and damaged is reduced; the leakage probability of power-assistedsteering oil is reduced; the normal operation of the automobile power-assisted steering system is further maintained, and the operation of the steering wheel by the vehicle owner is facilitated; thelimiting microspheres and the connecting ropes are used in cooperation in the using process, so that when the power-assisted steering pipe is extruded, the inward positioning ring and the outward bending ring on the selective positioning bending ring are connected more tightly when being extruded, and the stability of the selective positioning bending ring is higher.

Description

technical field [0001] The invention relates to the field of automobile hydraulic steering equipment, in particular to a self-returning power steering tube. Background technique [0002] Mechanical hydraulic power steering system is an economical power steering system, which generally consists of hydraulic pump, oil pipe (power steering pipe), pressure flow control valve body, V-shaped transmission belt, oil storage tank and other components. Regardless of whether the vehicle is turning or not, this system must work, and when the vehicle speed is low in large steering, the hydraulic pump needs to output more power to obtain a relatively large boost. The steering oil pump is installed on the engine, driven by the crankshaft through the belt and outputs hydraulic oil. The oil storage tank has oil inlet and outlet pipe joints, which are respectively connected with the steering oil pump and the steering control valve through the oil pipe (power steering pipe). The steering con...

Problems solved by technology

[0004] There is an overflow valve in the pipeline of the directional hydraulic booster. When the direction reaches the bottom for a short time, the hydraulic oil pressure is released. This valve can only be used for a short time. When hitting one side to death, the pipeline on one side will bear a lot of pressure, which may cause the oil pipe of the booster pump on this side to leak, or even burst on the spot, resulting in power steering failure and affecting the owner's control of the steering wheel. Make the car owner very easy to take the passenger's safety and there is a great hidden danger
