Abstract
The utility model belongs to the field of oil pipes in automobile power-assisted steering systems, and particularly relates to a valve for power-assisted steering oil pipes. The valve comprises an outer ring, wherein the two ends of the outer ring are respectively provided with a hole, a valve plate is fixed in the hole at one end of the outer ring, the periphery of the valve plate is hermetically fastened with the outer ring, the valve plate is provided with an oil through hole, a valve plug is arranged in the oil through hole, the inner wall of the oil through hole is provided with a seal component which is hermetically fastened with the valve plug, an elastic limit component is arranged in the outer ring, and the elastic limit component is fastened with the outer ring and arranged between the valve plug and the hole at the other end of the outer ring. The valve disclosed by the utility model has the advantages that the valve can carry out conducting or closing on the oil path of the power-assisted steering oil pipe timely, and can carry out limit adjustment through an elastic sheet, thereby improving the safety and comfortableness of automobiles.
Description
Technical field
The utility model belongs to the oil pipe field in the automobile assisted power steering system, and specifically a kind of servo-steering oil pipe is used valve.
Background technology
Modern automobile becomes the standing instrument of people's daily life, more and more in people's life, occupies an important position.Comfort level and the security requirement of people when driving is also increasingly high, and this just needs vehicle to have good maneuvering performance.Automobile assisted power steering system can provide automobile maneuvering performance preferably, is convenient for people to control better automobile, reduces dangerous.The servo steering system great majority of orthodox car adopt complete hydraulic booster, and promptly driving engine drives steering hydraulic pump through belt pulley and produces hydraulic booster.Yet this type of automobile power-assisted when low speed is little, and it is more heavy to turn to, and power-assisted is big when high speed, turn to too light, the influence comfort level and the safety of driving.On the other hand, because gasoline energy day more reduces, oil price is soaring day by day, and how reducing oil consumption as much as possible also is current problem to be solved.The servo steering system of orthodox car needs the bigger power of Hydraulic Pump output to obtain bigger power-assisted when low speed is turned.So, also increased oil consumption to a certain extent, wasted resource.
Summary of the invention
It is light that the problem that the utility model will solve is that the performance that improves the servo-steering oil pipe turns to when making it can when high speed, turn to heavy, low speed, and the utility model provides a kind of servo-steering oil pipe to use valve.
The utility model provides following technical scheme:
The servo-steering oil pipe is used valve, and it comprises an outer ring, and the two ends, outer ring are provided with perforate; One end perforate internal fixation has valve block, and with the outer ring sealing and fixing, valve block is provided with oil through around the valve block; Be provided with a spool in the oil through; The oil through inwall is provided with the sealing element with seal spool, is provided with an elasticity limiting component in the outer ring, and this elasticity limiting component and outer ring are fixed and are arranged between the other end perforate of spool and outer ring.
Described spool is the spheroid spool.
Described sealing element is a seal ring, and the cross section of seal ring is semicircle.
Described elasticity limiting component is a shell fragment, and the two ends of shell fragment are fixed on the inwall of outer ring.
The utility model has the advantages that and can be in time the oil circuit of steering oil pipe be carried out conducting or sealing, can also carry out spacing adjusting, improved the safety and the traveling comfort of automobile through shell fragment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the servo-steering oil pipe is used valve, and it comprises an outer ring 1; 1 two ends, outer ring are provided with perforate, and an end perforate internal fixation has valve block 2, around the valve block 2 with outer ring 1 sealing and fixing; Valve block 2 is provided with oil through, is provided with a spool 3 in the oil through, and the oil through inwall is provided with and spool 3 leak free sealing elements 4; Be provided with an elasticity limiting component 5 in the outer ring 1, this elasticity limiting component 5 and outer ring 1 are fixed and are arranged between the other end perforate of spool 3 and outer ring 1.
Described spool 3 is the spheroid spool.
Described sealing element 4 is a seal ring, and the cross section of seal ring is semicircle.
Described elasticity limiting component 5 is a shell fragment, and the two ends of shell fragment are fixed on the inwall of outer ring.
