Description
Technical field
The utility model belongs to universal joint apparatus technical field, particularly relates to a kind of rzeppa universal joint.
Background technique
Automobile rzeppa universal joint is the part belonged in auto parts and components, is mainly used for indispensable transmission part in vehicle speed control system, in the running of the speed control system of automobile, has important effect.The mechanism design of current rzeppa universal joint also exists unreasonable.The unreasonable design of automobile rzeppa universal joint also can make universal joint stressed unreasonable, and universal joint occurs crackle from stress raiser, and prolonged exercise can rupture.And current universal joint for automobile in the process used owing to using after a period of time, rub between universal joint for automobile and other component of automobile comparatively large, thus be easy to damage.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and provide a kind of rational in infrastructure, be connected firmly, the rzeppa universal joint that service time is long, its technological scheme is as follows:
Rzeppa universal joint, is characterized in that, described rzeppa universal joint comprises coupling shaft and housing, and described coupling shaft is stepped construction; Described housing comprises upper shell and lower shell body, described upper shell is hollow cylinder, upper enclosure inner wall tightens to be sticked and is equipped with wear-resisting inner housing, the inwall of wear-resisting inner housing is evenly distributed with several raceway grooves, boss is provided with between adjacent channel, the minimum wall thickness (MINI W.) of raceway groove is 1:2 with the ratio of the wall thickness of upper shell, and the wall thickness of boss is 3:1 with the ratio of the wall thickness of upper shell; Described lower shell body is hollow cone stage body, and the inside bottom of lower shell body is provided with groove; The outer wall of described lower shell body is positioned at and is provided with the first reinforcement ring bodies with the connecting part of coupling shaft, lower shell body outer wall is provided with the second reinforcement ring bodies, first strengthens ring bodies and second strengthens the diameter of ring bodies than being 1:1.5.
The rzeppa universal joint that the utility model provides, when in use, coupling shaft is that the miscellaneous part for connecting automobile is used, and the connection that the stepped construction of coupling shaft is is more stable, the coupling shaft being also simultaneously is less stressed, avoids coupling shaft in use to rupture.Upper shell is hollow cylinder, and lower shell body is hollow cone stage body, more stable when universal joint can be made to be connected with automobile miscellaneous part by difform housing, and difficult drop-off, has better flexibility simultaneously.Upper enclosure inner wall tightens to be sticked and is equipped with wear-resisting inner housing, wear-resisting inner housing be arranged so that whole upper casing is divided into two parts, more wear-resisting when making universal joint occur to rub with automobile miscellaneous part when in use, extend its service time.And the wall thickness of raceway groove and boss and the ratio of the wall thickness of upper shell can make more wear-resisting while, also can save material, and have more flexible performance.The connection being arranged so that coupling shaft and housing of the first reinforcement ring bodies is more stable, not easily ruptures when in use; Second strengthens arranging of ring bodies can make lower shell body have good intensity, and energy and first strengthens the intensity that the capable integrally effect of ring bodies further strengthens whole universal joint simultaneously.
The beneficial effects of the utility model are: rational in infrastructure, are connected firmly, and service time is long.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Embodiment is illustrated below in conjunction with Fig. 1:
As shown in Figure 1, rzeppa universal joint, described rzeppa universal joint comprises coupling shaft 1 and housing 2, and described coupling shaft 1 is stepped construction; Described housing 2 comprises upper shell 3 and lower shell body 4, described upper shell 3 is hollow cylinder, upper shell 3 inwall tightens to be sticked and is equipped with wear-resisting inner housing 5, the inwall of wear-resisting inner housing 5 is evenly distributed with several raceway grooves 6, boss 7 is provided with between adjacent channel 6, the minimum wall thickness (MINI W.) of raceway groove 6 is 1:2 with the ratio of the wall thickness of upper shell 3, and the wall thickness of boss 7 is 3:1 with the ratio of the wall thickness of upper shell 3; Described lower shell body 4 is hollow cone stage body, and the inside bottom of lower shell body 3 is provided with groove 8; The outer wall of described lower shell body 4 is positioned at and is provided with the first reinforcement ring bodies 9 with the connecting part of coupling shaft 1, lower shell body 4 outer wall is provided with the second reinforcement ring bodies 10, first and strengthens the diameter of ring bodies 9 and the second reinforcement ring bodies 10 than being 1:1.5.
When in use, coupling shaft is connected in the miscellaneous part of automobile.And the component of automobile are when being arranged in the housing of universal joint, owing to being contact with wear-resisting inner housing, so more wear-resisting when generation friction, its service time can be extended.Strengthen ring bodies and second by first and strengthen ring bodies, also can well prevent the fracture of whole universal joint.
