At present, it is 6 that the valve pocket oil groove in the existing valve pocket is generally magnitude setting, can only carry out upper oil cavitie and reflux, can not carry out lower oil cavitie and reflux, and the oil return weak effect, commonality is poor.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, the utility model provides a kind of steering box valve pocket of oil return better effects if,
To achieve these goals, the utility model has adopted following technical scheme:
A kind of steering box valve pocket, comprise the valve pocket body, the center of valve pocket body is provided with the central through hole that passes for automobile steering box steering shaft, the madial wall of the central through hole of described valve pocket is provided with 8 well-distributed valve pocket oil grooves, steering shaft oil groove on described valve pocket oil groove and the automobile steering device steering shaft lateral wall is equipped with, described valve pocket oil groove is strip, the length direction of described valve pocket oil groove is identical with the penetration direction of central through hole, described valve pocket oil groove comprises diapire and is distributed in the straight sidewall of diapire both sides, establishes the oilhole that is communicated with the motor turning Oil cylinder on the described diapire.
As preferably, described diapire is the circular arc cylinder, the cylinder cambered surface place axial direction of described diapire and vertical setting of axis body length direction of valve pocket body, the cylinder cambered surface place axial direction of described diapire is vertical with the plane at straight sidewall place, the cylinder cambered surface of described diapire extends to the inside face of central through hole, forms the cambered surface sidewall of valve pocket oil groove.After adopting above-mentioned preferred version, the oil return better effects if of steering box valve pocket of the present utility model.
As preferably, the lateral wall of described valve pocket body is provided with some circular grooves that are equipped with the motor turning Oil cylinder, and described oilhole is communicated with central through hole and circular groove.After adopting above-mentioned preferred version, steering box valve pocket of the present utility model can form better oil piping system by circular groove and automobile oil cylinder, makes the running of hydraulic power oil in the circuit system more steady, the oil return better effects if.
As preferably, the lateral wall end of described valve pocket body is along being provided with the bayonet lock groove, and described bayonet lock groove is near a side opening setting of valve pocket body outboard end.After adopting above-mentioned preferred version, steering box valve pocket of the present utility model can form snap fit by the bayonet lock on bayonet lock groove and the gear wheel shaft lateral wall, thereby make valve pocket and gear wheel shaft form more stable fixing, simultaneously, the engaging of this structure dismounting is convenient.
Steering box valve pocket of the present utility model adopts 8 valve pocket oil grooves, can make hydraulic oil carry out the lower oil cavitie oil return, and commonality is stronger.
