Abstract
A kind of hydraulic power steering gear gear, including cylindrical head, gear shape middle part and cylindrical rear portion, the reduced diameter of cylindrical head, gear shape middle part and cylindrical rear portion, a translot is provided with cylindrical head, and be provided with the axial mesopore of a radial hole and and connected with the translot, axial mesopore for and torsion bar interference fit；Axial mesopore therein is internal splined hole.Using structure of the present utility model, justified by torsion bar light in assembling strengthens the ability of its transmitting torque with the interference fit of internal spline, and come off risk reduction after torsion bar long-time use.
Description
Technical field
The utility model is related to a kind of auto parts and components, more particularly to a kind of hydraulic power steering gear gear.
Background technology
The basic structure of hydraulic power steering gear gear is as shown in figure 1, including 2 and of cylindrical head 1, gear shape middle part
Cylindrical rear portion 3, the reduced diameter of cylindrical head, gear shape middle part and cylindrical rear portion, in cylindrical
Head is provided with a translot 11, and is provided with a radial hole 12 and an axial mesopore 13 is connected with the translot.Hydraulic booster turns
To device gear in assembling with torsion bar interference fit, and transmitting torque.In the hydraulic power steering gear gear of prior art, axle
The smooth circular hole of a diameter of 10mm to mesopore 13, and the diameter of torsion bar is also 10mm, in assembling by torsion bar light justify with
The cooperation transmitting torque of circular hole, the ability of its transmitting torque is weaker, is easily come off after torsion bar long-time use.
Utility model content
The purpose of this utility model, exactly in order to solve the above problems, there is provided a kind of hydraulic pressure that can realize axially position is helped
Power steering gear gear.
In order to achieve the above object, the utility model employs following technical scheme：A kind of hydraulic power steering gear gear,
Including cylindrical head, gear shape middle part and cylindrical rear portion, after cylindrical head, gear shape middle part and cylindrical
The reduced diameter in portion, a translot is provided with cylindrical head, and be provided with a radial hole and an axial mesopore with
The translot is connected, and axial mesopore is used for and torsion bar interference fit；It is characterized in：The axial mesopore is internal splined hole.
The path of the internal splined hole is 9.5mm, a diameter of 10mm of the torsion bar.
Using structure of the present utility model, justified by torsion bar light in assembling makes it transmit torsion with the interference fit of internal spline
The ability enhancing of square, come off risk reduction after torsion bar long-time use.
Brief description of the drawings
The structural representation of Fig. 1 prior art hydraulic power steering gear gears；
Fig. 2 is the structural representation of the utility model hydraulic power steering gear gear.
Fig. 3 is the A-A of Fig. 2 to sectional view.
Specific embodiment
Referring to Fig. 2, Fig. 3, hydraulic power steering gear gear of the present utility model, including in cylindrical head 1, gear shape
Portion 2 and cylindrical rear portion 3, the reduced diameter of cylindrical head, gear shape middle part and cylindrical rear portion, in cylinder
Bodily form head 1 is provided with a translot 11, and is provided with a radial hole 12 and an axial mesopore 131 is connected with the translot, axial
Mesopore is used for and torsion bar interference fit；The axial mesopore is internal splined hole.The path of the internal splined hole be 9.5mm, torsion bar it is straight
Footpath is 10mm.Internal splined hole and torsion bar interference fit.Torsion bar, can by the ability enhancing of transmitting torque after internal splined hole crimp
By property enhancing.
