Abstract
The utility model discloses an auto steering sleeve and telescopic connection structure, including sleeve and sleeve, the telescopic global equipartition of going up is riveted a little, rivet and a little form the arch on the sleeve internal surface. Riveting of the global upward equipartition of sleeve a little is spiral distribution. The utility model has the advantages of low -cost simple process and easy control of the routed power of contracting and reliability height.
Description
Technical field
The utility model relates to a kind of Automotive Steering Technology, particularly the connection structure of a kind of motor turning sleeve and sleeve.
Background technology
The connection structure of existing steering intermediate shaft sleeve and sleeve is spline joint, sleeve is evenly equipped with four radial holes to be communicated with two circular grooves that tween drive shaft sleeve side face is arranged vertically respectively, by being injection-moulded in above-mentioned four radial holes and two circular grooves form four injection mouldings rods and two annular body.The shortcoming of this structure is, due to the gap between metal spline, when sleeve bears moment of torsion, injection moulding rod withstands shocks shearing force, injection moulding rod easily produces fracture, crumple energy-absorbing function is slackened, simultaneously, because the pressure needed during injection moulding is comparatively large, easily produces and run glue, be thus difficult to accurately control crumple power.
Summary of the invention
The utility model object is to provide a kind of connection structure making simple and convenient and crumple power and hold manageable a kind of motor turning sleeve and sleeve.
The technical solution of the utility model is, the connection structure of a kind of motor turning sleeve and sleeve, comprises sleeve and sleeve, it is characterized in that: the side face of described sleeve is evenly equipped with riveting point, and described riveting point forms projection in sleeve interior surface.Riveting point uniform on described sleeve side face is Spiral distribution.
The utility model has the simple and crumple power of low cost process compared with the prior art and easily controls and the high advantage of reliability.
Accompanying drawing illustrates:
Fig. 1 is front view of the present utility model; The A-A cutaway view of Fig. 1 during Fig. 2.
Detailed description of the invention:
The technical solution of the utility model as shown in Figure 1-2, after sleeve 1 and sleeve 2 are assembled, on the side face of sleeve, riveting point is carried out with compression machine, described riveting point 3 is that 4 spirals are distributed on sleeve side face, according to the concrete crumple power requirement of sleeve and sleeve, determine concrete riveting point quantity, described riveting point is at least 2.By controlling riveting point quantity and position, crushing force being evenly distributed on each riveting point and can controlling crushing force comparatively accurately.
Principle of work of the present utility model, the projection that riveting point on sleeve is formed in sleeve interior surface and tween drive shaft sleeve form interference fit, when impact load exceeds the loadlimit of permission, riveting just lost efficacy, sleeve and tween drive shaft sleeve just relative sliding, now, riveting point meeting shock absorbing load, and the resistance of constant slip is provided.
The manufacture craft of above-mentioned riveting dot structure is extremely easy, and the high and crumple power produced of production efficiency easily controls.
Claims (2)
1. a connection structure for motor turning sleeve and sleeve, comprises sleeve and sleeve, it is characterized in that: the side face of described sleeve is evenly equipped with riveting point, and described riveting point forms projection in sleeve interior surface.
2. the connection structure of a kind of motor turning sleeve as claimed in claim 1 and sleeve, is characterized in that: riveting point uniform on described sleeve side face is Spiral distribution.
