Abstract
The utility model discloses an assembly structure of a gear shaft and a torsion bar of a steering device, which comprises a gear shaft and a torsion bar connected with the gear shaft, wherein the connection end of the gear shaft and the torsion bar and the end part of the gear shaft are provided with shaft holes, the end part of the torsion bar is in the shape of a cylindrical head, the shaft holes of the cylindrical head are in a concave-convex type interference fit, and the inner wall of the shaft hole of the gear shaft is provided with a convex edge engaged with the cylindrical head of the torsion bar, or the circumferential wall of the cylindrical head at the end part of the torsion bar is provided with a convex edge engaged with the shaft hole of the gear shaft. The assembly structure enhances the assembly stability and reliability effectively and lowers the processing cost.
Description
Technical field
The utility model relates to the mounting structure of power steering gear wheel shaft and torsion bar, guarantees the stability and the reliability of disposable assembling.
Background technology
The gear wheel shaft of power steering connects together by assembling with torsion bar, common structure is that the axis hole of gear wheel shaft and the axle of torsion bar adopt flush fit to pack into, again bore with the cooperation place of axis normal direction, hinge one hole, be pressed into that a friction tight direct selling finishes.There is certain problem in this structure in the assembling and the course of processing.1. increased a riveting pin structure.2. bore on gear wheel shaft that riveting pin need be after being pressed into and the torsion bar, fraising, because the material and the heat treatment hardness of gear wheel shaft and torsion bar are different, one pulls out of hole, reams, and is difficult to guarantee with general method the circularity and the aperture size of pin-and-hole, the riveting pin effect that out of reach is desirable.3. because deflector torsion bar when work is being subjected to the reverse load of torsional direction constantly, the time has been grown pin-and-hole and has occurred little distortion, loosening phenomenon easily.
The utility model content
At the problems referred to above, the technical matters that the utility model need solve provides the more reliable and more stable deflector gear wheel shaft of a kind of assembling and the mounting structure of torsion bar.
For solving the problems of the technologies described above, technical scheme provided by the invention is: the mounting structure of a kind of deflector gear wheel shaft and torsion bar, comprise gear wheel shaft and with gear wheel shaft bonded assembly torsion bar, coupling end at gear wheel shaft and torsion bar, the end of gear wheel shaft is provided with axis hole, the torsion bar end is socket cap, axis hole and socket cap are lenticular interference fit, and the shaft hole inner wall of described gear wheel shaft is provided with the protruding stupefied of torsion bar socket cap interlock or the socket cap circle wall in the torsion bar end and is provided with protruding stupefied with the axis hole interlock of gear wheel shaft.
Further: in the mounting structure of above-mentioned deflector gear wheel shaft and torsion bar, the axis hole of described gear wheel shaft is set to female splines formula axis hole, and perhaps the socket cap in the torsion bar end is set to male splines formula socket cap.Described axis hole end face inward flange is provided with the riveting point that further blocks the torsion bar socket cap.
Compared with prior art, in the mounting structure of above-mentioned deflector gear wheel shaft and torsion bar, the shaft hole inner wall of described gear wheel shaft is provided with the protruding stupefied of socket cap interlock or the socket cap circle wall in the torsion bar end and is provided with protruding stupefied with the axis hole interlock of gear wheel shaft.Promptly in original gear axis hole and the assembling of torsion bar axle, change the press mounting structure that hole or torsion bar axle one side adopt spline into.Be that the gear wheel shaft internal splined hole is joined torsion bar axial cylindrical head or the gear axis hole is joined torsion bar male splines socket cap.The employing interference fit is pressed into, and the convexconcave part of spline is filled by the metal of interference, guarantees gear wheel shaft and torsion bar reliability in relative rotation.Be pressed into the back and carry out two places or many places riveting point, guarantee that gear wheel shaft and torsion bar under normal operation, relative motion can not take place in the end of gear axis hole or splined hole.The beneficial effects of the utility model are: it has simplified mounting structure, effectively raises the stability and the reliability of assembling, cuts down finished cost.
Description of drawings
