Abstract
The utility model discloses a rotor of a full-hydraulic steering gear, comprising a body. A spline shaft hole is arranged on the body, and a circular-ring-shaped sealing groove is arranged on one side surface of the body. A chamfer is arranged on an opening of the spline shaft hole in the body. The rotor of the full-hydraulic steering gear has the advantages that a driver feels light after the rotor is used, and the torsion is small.
Description
Technical field
The utility model relates to a kind of spare and accessory parts of all-hydraulic steering gear, relates in particular to a kind of rotor of all-hydraulic steering gear.
Background technology
The rotor of existing all-hydraulic steering gear is very high with the endplay requirement of stator assembling, and designing requirement is 0.01 ~ 0.02mm.Common process is the method that adopts match grinding.If this method rotor is tight with the gap between the stator, it is motionless that rotor changes; The gap pine, the bearing circle dish is heavy, and promptly the terminal point moment of torsion is greater than 2N.m, and the chaufeur feel is tired.
Summary of the invention
The purpose of this utility model is to provide a kind of use back chaufeur feel light, the rotor of the all-hydraulic steering gear that moment of torsion is little.
In order to achieve the above object, the technical solution of the utility model is: a kind of rotor of all-hydraulic steering gear, comprise body, and offer the spline axis hole on the body, have the annular seal groove on the side of described body.
The aperture of the spline axis hole on the described body has chamfering.
The groove width of described annular seal groove is 2 ~ 4mm.
After adopting said structure, designed an annular seal groove by universal driving shaft one end, loaded onto seal ring, blocked the hydraulic oil string, improved the terminal point moment of torsion to inner chamber at rotor.The result shows through testbed trial, and moment of torsion is less than the effect of 2N.m fully, and chaufeur practical operation feel is light and handy.
Description of drawings
Fig. 1 is the structural representation of the rotor of original all-hydraulic steering gear;
Fig. 2 is the A-A direction cutaway view of Fig. 1;
Fig. 3 is the structural representation of the rotor of all-hydraulic steering gear of the present utility model;
Fig. 4 is the B-B direction cutaway view of Fig. 3.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Fig. 3,4, the rotor of a kind of all-hydraulic steering gear of the present utility model comprises body 1, offers spline axis hole 2 on the body 1, has annular seal groove 3 on the side of described body 1.
Shown in Fig. 3,4, for easy for installation, the aperture of the spline axis hole 2 on the described body 1 has chamfering 2-1.
Shown in Fig. 3,4, the groove width of described annular seal groove 3 is 2 ~ 4mm.
The utility model is loaded onto seal ring owing to designed an annular seal groove at rotor by universal driving shaft one end, has blocked the hydraulic oil string to inner chamber, has improved the terminal point moment of torsion.The result shows through testbed trial, and moment of torsion is less than the effect of 2N.m fully, and chaufeur practical operation feel is light and handy.
