Problems solved by technology

[0003] When the car is turning, when the hydraulic oil flows from the fuel tank to the hydraulic pump through the oil pipe, hydraulic shock will occur, hydraulic vibration will be generated, and noise will be emitted, and the car will inevitably bump and vibrate when the car is running, resulting in a shock in the fuel tank. The hydraulic oil will vibrate, and the hydraulic power steering system in the prior art has poor cushioning performance, resulting in the above vibrations easily causing damage to the mechanical parts and seals in the steering system, which has certain potential safety hazards

Embodiment 1

[0041] see Figure 1-3 , a hydraulic power steering system with multiple buffer structures, including a fuel tank 002, a hydraulic pump 003, and a steering gear 004 connected to both the fuel tank 002 and the hydraulic pump 003, the fuel tank 002 is connected to the hydraulic pump 003 through a buffer oil pipeline 001, and the buffer oil pipeline 001 includes a long oil guide pipe 101, a thick buffer pipe 102, and a short connecting pipe 103 that are connected to each other. The long oil guide pipe 101 and the short connecting pipe 103 are respectively fixedly connected to the upper and lower ends of the thick buffer pipe 102. The inner wall of the thick buffer section pipe 102 is fixed with matching elastic slings 105, and the inner walls on both sides of the damping inner sleeve 104 are fixedly connected with two elastic slings 105, and the elastic slings 105 are far away from the damping inner wall. One end of the inner wall of the bushing 104 is fixedly connected with a da...

Abstract

The invention discloses a hydraulic power-assisted steering system with multiple buffer structures, belongs to the technical field of hydraulic power-assisted steering, and can realize that a specially-made buffering oil conveying pipe is arranged, when hydraulic oil flows to a hydraulic pump from an oil tank through the buffering oil conveying pipe, an elastic lifting rope, a buffering oil receiving sleeve and an inflation ball bag in the buffering oil conveying pipe can provide a buffering effect respectively, vortexes can be generated through movement of a damping inner sleeve relative to adamping cylindrical block, a buffering effect is further provided, and therefore impact and vibration generated when hydraulic oil flows to the hydraulic pump can be greatly reduced. As the oil tankis arranged, when an automobile jolts, a buffer spring and an elastic connecting piece can provide a buffer effect respectively, so that vibration of hydraulic oil in the oil tank is buffered, damageof vibration of the hydraulic oil to mechanical parts and sealing parts in a steering system can be remarkably reduced through the arrangement of the multiple buffer structures, the service life of the system is effectively prolonged, and practicability is greatly improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic power steering, and more specifically relates to a hydraulic power steering system with multiple buffer structures. Background technique [0002] The main function of the power steering of the car is to assist the driver to reduce the intensity of the steering wheel and drive the car more easily, and the quiet driving environment can make the driver feel relaxed and prevent premature driving fatigue. [0003] When the car is turning, when the hydraulic oil flows from the fuel tank to the hydraulic pump through the oil pipe, hydraulic shock will occur, hydraulic vibration will be generated, and noise will be emitted, and the car will inevitably bump and vibrate when the car is running, resulting in a shock in the fuel tank. The hydraulic oil will vibrate, and the hydraulic power steering system in the prior art has poor cushioning performance, which causes the above vibration to easily cause dama...
