Abstract
The utility model provides an auto steering ball round pin belongs to auto -parts technical field. It has solved the problem of the current great easy wearing and tearing of auto steering ball round pin frictional force. This auto steering ball round pin, including bulb, connecting rod and threaded rod, the both ends of connecting rod link to each other with bulb and threaded rod respectively, and the lateral wall of bulb is equipped with the annular groove, annular groove and the coaxial setting of connecting rod, the annular groove is embedded to have ball, ball protrusion in the lateral wall of bulb. This auto steering ball round pin has the advantage that frictional force is less and the shelf life is longer.
Description
Technical field
The utility model belongs to technical field of automobile, relates to one and turns to ball pin, particularly a kind of automotive steering ball pin.
Background technology
Interconnective by cue ball pin between the wheel of automobile and axletree, simultaneously wheel with between deflecting bar also with turning to ball pin to be connected, existing cue ball pin and turn to ball pin to be design a thread rod in path one end of taper radius stay, a solid sphere is designed in one end, large footpath of taper radius stay, especially the surface configuration of solid sphere part will have quite high dimensional accuracy and form accuracy, have to pass through fine grinding and just can reach requirement, this just brings very large difficulty to processing.
A kind of automotive steering ball pin (application number: 201310456474.2) comprise ball pin body disclosed in Chinese patent literature, described ball pin body comprises centrum, be connected to centrum one end and the thread rod be connected with steering track rod, the face, pommel that is connected to the centrum other end, face, pommel is provided with groove, and the degree of depth of groove is greater than pommel radius surface.But the face, pommel of this automotive steering ball pin adopts cliding friction, therefore its friction force more greatly and easily wear and tear, and have impact on service life.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of automotive steering ball pin with friction force less and longer service life.
The purpose of this utility model realizes by following technical proposal: automotive steering ball pin, comprise bulb, pipe link and thread rod, the two ends of described pipe link are connected with described bulb and described thread rod respectively, it is characterized in that, the lateral wall of described bulb is provided with annular groove, described annular groove and described pipe link are coaxially arranged, and described annular groove is embedded with ball, and described ball protrudes from the lateral wall of described bulb.
In use, because the lateral wall of bulb is provided with annular groove, ball is provided with in annular groove, therefore make the bulb of this automotive steering ball pin when connecting, its friction is friction of rolling, relatively common cliding friction, the friction force that this bulb is subject to is less, makes this automotive steering ball pin have longer service life.
In above-mentioned automotive steering ball pin, the quantity of described annular groove is 1-3 and all be arranged in parallel.The quantity of annular groove is 1-3, makes originally to turn to ball pin to have less friction force.
In above-mentioned automotive steering ball pin, described bulb has near the other end of pipe link groove of stepping down, and the bottom surface of described groove of stepping down is curved.By arranging groove of stepping down, can make originally to turn to ball pin to store lubricating oil, decreasing material simultaneously.
In above-mentioned automotive steering ball pin, described pipe link comprises tapered rod and straight-bar, and described tapered rod is connected with described bulb, and described straight-bar is connected with described thread rod.By arranging tapered rod, make originally to turn to ball pin to have good intensity and certain guide effect.
In above-mentioned automotive steering ball pin, the tapering β of described tapered rod is 6 °-10 °.The tapering β of tapered rod is 6 °-10 °, has structure comparatively reasonably advantage.
Compared with prior art, this automotive steering ball pin has the following advantages:
1, because the lateral wall of bulb is provided with annular groove, be provided with ball in annular groove, the friction force that this bulb is subject to is less, makes this automotive steering ball pin have longer service life;
2, the quantity of annular groove is 1-3, makes originally to turn to ball pin to have less friction force;
3, by arranging tapered rod, make originally to turn to ball pin to have good intensity and certain guide effect.
Accompanying drawing explanation
Fig. 1 is the schematic front view of this automotive steering ball pin.
Fig. 2 is the partial schematic sectional view of this automotive steering ball pin.
In figure, 1, bulb; 1a, annular groove; 1b, groove of stepping down; 2, pipe link; 2a, tapered rod; 2b, straight-bar; 3, thread rod; 4, ball.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As illustrated in fig. 1 and 2, automotive steering ball pin, comprises bulb 1, pipe link 2 and thread rod 3, and pipe link 2 comprises tapered rod 2a and straight-bar 2b, and tapered rod 2a is connected with bulb 1, and straight-bar 2b is connected with thread rod 3.The lateral wall of bulb 1 is provided with 2 annular groove 1a be arranged in parallel, and annular groove 1a and pipe link 2 are coaxially arranged, and annular groove 1a is embedded with ball 4, and ball 4 protrudes from the lateral wall of bulb 1.The tapering β of tapered rod 2a is 6 °-10 °.By arranging tapered rod 2a, make originally to turn to ball pin to have good intensity and certain guide effect.
Bulb 1 has near the other end of pipe link 2 the groove 1b that steps down, and the bottom surface of the groove 1b that steps down is curved, can make originally to turn to ball pin to store lubricating oil, decreases material simultaneously.
In use, lateral wall due to bulb 1 is provided with annular groove 1a, ball 4 is provided with in annular groove 1a, therefore make the bulb 1 of this automotive steering ball pin when connecting, its friction is friction of rolling, relatively common cliding friction, the friction force that this bulb 1 is subject to is less, makes this automotive steering ball pin have longer service life.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ bulb 1, annular groove 1a herein, the term such as the groove 1b that steps down, pipe link 2, tapered rod 2a, straight-bar 2b, thread rod 3, ball 4, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
