Abstract
The utility model relates to a stroke position limiting valve of a steering gear, in particular to a stroke position limiting valve of a steering gear, which is widely applied to large-size and medium-size heavy-duty automobile integral motive power steering gear devices. The position limiting valve comprises a push pipe, a position limiting sleeve, a position limiting valve seat, a position limiting valve core and a spring, wherein the position limiting sleeve and the position limiting valve seat are symmetrically arranged at both ends of the push pipe, the position limiting valve core is arranged inside the push pipe, the spring is sheathed and arranged on the position limiting valve core, and the position limiting valve seat is sheathed and arranged on the position limiting valve sleeve, wherein the pressing distance of the position limiting valve seat into the position limiting valve sleeve can be regulated. The utility model has the advantages of simple and reasonable structure, convenient processing and assembly, high production efficiency, safety, reliability and the like.
Description
Technical field
The utility model relates to a kind of distance caging device, a kind of specifically deflector stroke limit valve that is widely used in big, the medium and heavy automobile integral power steering apparatus.
Background technology
Present development along with domestic and international transportation; in big, medium and heavy automobile; according to user's operating needs; be provided with the stroke limit valve on the power steering gear assembly; when the current axis wheel flutter forwarded left and right sides end position to, it is maximum that steering swivel system pressure reaches, the off-load of stroke limit valve; system pressure is reduced to 3.5～5.5Mpa, and steering swivel system is shielded.During this deflector entrucking, the output shaft corner is in ± 30 °～± 45 ° scopes.There are many shortcoming and defect in existing stroke limit valve, is in particular in: complex structure, processing and assembling inconvenience, production efficiency are low, poor stability.
Summary of the invention
The purpose of this utility model be to provide a kind of simple and reasonable, processing and easy to assembly, production efficiency is high, safe and reliable deflector stroke limit valve.
The purpose of this utility model is to realize like this, this limit valve comprises ejector sleeve, is symmetricly set on the spacing valve pocket and the spacing valve seat at ejector sleeve two ends, is arranged on the spacing spool of ejector sleeve in-to-in, is sleeved on the spring on the spacing spool, described limit valve cover for seat is contained in limit valve and puts, and wherein spacing valve seat is pressed into the distance of spacing valve pocket and can adjusts.
The utility model has reduced the part parts simultaneously owing to adopted said structure on the original design architecture basics, make easy to adjustly, assembles simplyr, and production efficiency improves greatly.Promptly reduce cost of product, improved product design again.
Description of drawings
Fig. 1 is a deflector stroke limit valve integral structure scheme drawing.
The specific embodiment
Shown in accompanying drawing 1: this limit valve comprises ejector sleeve 4, is symmetricly set on the spacing valve pocket 1 and the spacing valve seat 2 at ejector sleeve 4 two ends, is arranged on the spacing spool 3 of ejector sleeve 4 in-to-ins, is sleeved on the spring 5 on the spacing spool 3, described spacing valve seat 2 is sleeved on the spacing valve pocket 1, and wherein spacing valve seat 2 is pressed into the distance of spacing valve pocket 1 and can adjusts.
Principle of work:
According to operating needs, when the current axis wheel flutter forwarded left and right sides end position to, it is maximum that steering swivel system pressure reaches, the off-load of stroke limit valve, and system pressure is reduced to 3.5～5.5Mpa, and steering swivel system is shielded.During this deflector entrucking, the output shaft corner is in ± 30 °～± 45 ° scopes, but stroke limit valve automatic compensation, method of adjustment is as follows: 1. before tire does not land, steering wheel rotation, two end positions (colliding with the wheel caging bolt) about tire is forwarded to feel obviously to turn to till the hand-power increase that this moment, the stroke limit valve was that automatic compensation finishes.2. deflector is when dispatching from the factory, and the stroke limit valve transfers in advance ± and 30 °, therefore before the entrucking of stroke limit valve is adjusted, do not allow to change arbitrarily the output shaft corner.If must change the output shaft angle, then maximum can not surpass ± 30 °, otherwise will change stroke limit valve initial angle.
