Abstract
The invention relates to a rotating valve assembly of a dual pin stop, which comprises steering screw, valve core, roller bearing, O ring, sealing ring, round post in, twist bar, featuring in the steering screw valve part with two symmetrical ladder hole AC and BD being coaxial with the round post pin, stop slot on the corresponding AC, BD valve core and ladder hole, stop pin inserting into the corresponding ladder hole AC, BD and stop slot and the two rivet at the hole end surface. It is simple in structure, shortened in steering valve length, reduced a length m compared with the single pin stop steering valve. It simplifies the machining process, reduces product cost, and improves the assembly adjusting feature of the steering valve assembly.
Description
Technical field
The present invention relates to a kind of steering valve power steering, especially relate to a kind of valve packe of limited by double-pin.
Background technology
The rotary valve inhibiting device of steering valve power steering is just like the spacing valve packe of the protruding fork of flange shown in Fig. 8,9 at present, the rotary valve of this assembly links into an integrated entity by pin and input shaft, and the projection of groove by the input shaft spacer flanger and steering screw valve body is spacing, in the middle of the input shaft of this inhibiting device valve packe how a flange, increased the radial dimension and the axial dimension of assembly.Figure 10,11 is depicted as the spacing valve packe of spline, the rotary valve of this valve packe links into an integrated entity by pin and input shaft, and the female splines of male splines by the input shaft left end and steering screw valve body is spacing, but the interior male splines processing technology complexity of the steering screw valve body of the valve packe of this inhibiting device and input shaft.Figure 12,13 is depicted as the spacing valve packe of single pin, the rotary valve of this valve packe and input shaft are an integral body, single pin is pressed in the radial hole of steering screw valve body, and pass the rotation of the radial hole restriction rotary valve of rotary valve, be not easy to change rotary valve when carrying out stand test in the screw rod valve body but the rotary valve that has torsion bar in the valve packe of this inhibiting device is packed into, can't repeat debugging, the axial dimension of rotary valve is also longer.
Summary of the invention
The object of the invention is to provide a kind of valve packe of limited by double-pin at above-mentioned the deficiencies in the prior art.Its technical scheme is: a kind of valve packe of limited by double-pin, comprise steering screw, spool, needle bearing, O shape circle, seal ring, straight pin, torsion bar, it is characterized in that: the valve body of steering screw is arranged with the stepped hole AC and the BD of two symmetries, and stepped hole AC, BD are coaxial with straight pin; Be provided with position-limited trough with stepped hole AC, BD correspondence position on the spool, be with step-like locating dowel pin to be pressed in cooresponding stepped hole AC, BD and the position-limited trough and in hole end surface two riveting point rivetings.
Described position-limited trough has opening, and it is shaped as the cone tank of band R shape.
The present invention compares with existing rotary valve position limiting structure, and is not only simple in structure, and shortened the length of rotary valve valve body part, compares with the spacing rotary valve of single pin, shortened a length m.The present invention has also alleviated deflector weight, and simplified processing process has reduced the cost of product, has improved the assembling and setting performance of valve packe.

The specific embodiment
A kind of valve packe of limited by double-pin, comprise steering screw 1, spool 2, needle bearing 5,6, O shape circle 7, seal ring 8, straight pin 9,11, torsion bar 10, it is characterized in that: the valve body of steering screw 1 is arranged with the stepped hole AC and the BD of two symmetries, and stepped hole AC, BD are coaxial with straight pin 9; Be provided with position-limited trough 2-1 with stepped hole AC, BD correspondence position on the spool 2, be with step-like locating dowel pin 3,4 to be pressed among cooresponding stepped hole AC, BD and the position-limited trough 2-1 and, to prevent locating dowel pin 3,4 longitudinal travels in hole end surface two riveting point 1-1 rivetings.Described position-limited trough 2-1 has opening, and it is shaped as the cone tank of band R shape.In the time of in spool 2 band torsion bars 10 are packed steering screw 1 valve body hole into, locating dowel pin 3,4 just is inclusive in the taper position-limited trough 2-1 of spool 2 afterbodys, locating dowel pin 3,4 is exactly the maximum range that steering screw 1 rotates relative to spool 2 with the maximum clearance of taper position-limited trough 2-1, when rotary valve on the centering test cell, debug by the force characteristic curve, and after rotary valve fix with straight pin 9 by the afterbody of torsion bar 10 and steering screw 1, two sides of spool 2 afterbody taper position-limited trough 2-1 should be consistent with the distance of pair locating dowel pins.Double-pin rotary valve inhibiting device not only can accurately limit the corner of rotary valve, and bear the rotating torque of forced steering, because rotary valve position-limited trough 2-1 has opening, change rotary valve when being convenient to the valve packe debugging, the valve packe of also being convenient to this structure simultaneously in short structure deflector mounting arrangements.When the performance when valve packe is debugged does not meet designing requirement, can change another spool 2 very easily.
