In order to solve the problems of the technologies described above, the utility model provides a kind of steering wheel care set, it is located between steering wheel shell and mandrel, comprise the care set body of annular, described care set body outer surface is provided with the circular groove that circumference is arranged, described care set body lower part is provided with the block protruding described care set body outer surface, and described care set body is provided with from its upper end to downward-extension or the strip breach by predetermined aligned transfer that upwards extends from lower end.
As the improvement of such scheme, described care set body is provided with from its upper end to downward-extension or the lower breach referring to the upper breach from described care set body upper end to downward-extension by the strip breach of predetermined aligned transfer and upwards extend from described care set body lower end that upwards extends from lower end.
As the improvement of such scheme, described upper breach comprise breach on a pair rotational symmetric first and two pairs of axisymmetric and and on described first of both sides breach distance same distance second on breach.
As the improvement of such scheme, the length of described upper breach and lower breach is greater than the half of described care set body height.
As the improvement of such scheme, described lower breach totally 4, to be equidistantly located on described first on breach and second between breach respectively.
As the improvement of such scheme, the external diameter of described care set body is 31mm, and internal diameter is 24mm; On described first, the width of breach is 2-1.8mm, and on second, the width of breach is 4-1.8mm.
As the improvement of such scheme, the quantity of described circular groove is 2.
As the improvement of such scheme, in described circular groove, be provided with O type circle.
As the improvement of such scheme, described care set body is made up of thermoplastic polyester elastomer (TPEE).
Implement the utility model, there is following beneficial effect:
Care set body described in the utility model is provided with from its upper end to downward-extension or the strip breach by predetermined aligned transfer that upwards extends from lower end, and during care set work, lubricant oil can enter from described strip breach, keeps the lubrication of mandrel and the cooling of care set self.
The radial direction that described upper breach and lower breach strengthen care set extends ability, makes care set can Fast Restoration after the impact being subject to mandrel, remains on safety range after making care set long-term work with the gap of mandrel and steering wheel shell.
Accompanying drawing explanation
Fig. 1 is the working state schematic representation of a kind of steering wheel care set of the utility model;
Fig. 2 is the perspective view of a kind of steering wheel care set of the utility model;
Fig. 3 is the plan structure schematic diagram of a kind of steering wheel care set of the utility model;
Fig. 4 be a kind of steering wheel care set of the utility model look up structural representation.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-Figure 4, the utility model embodiment provides a kind of steering wheel care set, it is located between steering wheel shell 1 and mandrel 2, comprise the care set body 3 of annular, described care set body 3 outer surface is provided with the circular groove 4 that circumference is arranged, described care set body 3 bottom is provided with the block 5 protruding described care set body 3 outer surface, and described care set body 3 is provided with from its upper end to downward-extension or the strip breach by predetermined aligned transfer that upwards extends from lower end.Described block 5 is for being fixed on the precalculated position of steering wheel shell 1 by care set body 3.
Care set body 3 described in the utility model is provided with from its upper end to downward-extension or the strip breach by predetermined aligned transfer that upwards extends from lower end, during care set work, lubricant oil can enter from described strip breach, keeps the complete lubrication of mandrel 2 and the cooling of care set self.
Preferably, described care set body 3 is provided with from its upper end to downward-extension or the lower breach 7 referring to the upper breach (6a, 6b) from described care set body 3 upper end to downward-extension by the strip breach of predetermined aligned transfer and upwards extend from described care set body 3 lower end that upwards extends from lower end.
It should be noted that, described upper breach (6a, 6b) and lower breach 7 radial direction that strengthens care set extend ability, make care set can Fast Restoration after the impact being subject to mandrel 2, after making care set long-term work, remain on safety range with the gap of mandrel 2 and steering wheel shell 1.
Preferably, described upper breach (6a, 6b) comprise breach 6a and two pair axisymmetric on a pair rotational symmetric first and and on described first of both sides breach 6a distance same distance second on breach 6b.
Preferably, the length of described upper breach (6a, 6b) and lower breach 7 is greater than the half of described care set body 3 height.
Preferably, described lower breach 7 totally 4, to be equidistantly located on described first on breach 6a and second between breach 6b respectively.
Preferably, the external diameter of described care set body 3 is 31mm, and internal diameter is 24mm; On described first, the width of breach 6a is 2-1.8mm, and on second, the width of breach 6b is 4-1.8mm.
Preferably, the quantity of described circular groove 4 is 2.O type circle 8 is provided with in described circular groove 4.
It should be noted that, because O type circle has elasticity, two O type circles 8 can fill the gap between care set and steering wheel shell 1, prevent care set and steering wheel shell 1 from colliding and abnormal sound occurs.
