Abstract

Portable universal joint of lightweight. The universal joint mainly solves the problems that the existing universal joint fails due to the fact that the star-shaped sleeve ball path is abraded, seriously fails and is broken, and the whole universal joint is replaced if the existing universal joint is integral. The method is characterized in that: casing (1) is including sleeve pipe (12) and joint (11) that can dismantle the connection, the intraductal star cover (122) that is equipped with channel (121) and is used for the jackshaft to pack into of cover still includes holder (3), be equipped with spin (31) on the holder, the spin with the star cover cooperatees, the spin with the channel cooperatees, be equipped with minor axis (111) on the joint. The utility model provides a portable universal joint of lightweight, convenient to detach changes, and when the star cover became invalid, the joint can used repeatedly, improves the reuse rate of product.

Description

Light-weight movable universal joint

Technical Field

The utility model relates to an automobile parts field, concretely relates to portable universal joint of lightweight.

Background

The universal joint is a part for realizing variable angle power transmission, is used for changing the position of the transmission axis direction, and is a joint part of a universal transmission device of an automobile driving system. The universal joint is combined with a transmission shaft and is called a universal joint transmission device. On a vehicle driven by a rear wheel of a front engine, a universal joint transmission device is arranged between an output shaft of a transmission and an input shaft of a main speed reducer of a drive axle; the front engine front wheel driven vehicle omits a transmission shaft, and the universal joint is arranged between a front axle half shaft which is responsible for driving and steering and wheels.

The conventional universal joint generally fails due to the fact that the ball path of the inner race is abraded, seriously fails and breaks due to fatigue, and if the conventional universal joint is integrated, the whole universal joint is replaced.

SUMMERY OF THE UTILITY MODEL

In order to overcome the not enough of background art, the utility model provides a portable universal joint of lightweight has mainly solved present universal joint inefficacy and has all been the serious fatigue failure of star cover ball way wearing and tearing and break, if it is integral, will lead to the problem that whole universal joint all must be changed.

The utility model discloses a concrete implementation scheme does:

portable universal joint of lightweight, which comprises a housin, the casing is including dismantling the sleeve pipe and the joint of connection, the intraductal trench that is equipped with of cover and is used for the jackshaft to pack into is overlapped, still includes the holder, be equipped with the spin on the holder, the spin with the overlap of star cooperatees, the spin with the trench cooperatees, be equipped with the minor axis on the joint.

The sleeve is connected with the joint through a fastener.

And a sealing ring is arranged between the sleeve and the opposite surface of the joint.

The groove comprises a first cambered surface and a second cambered surface which are tangent to the rolling balls, and a third cambered surface and a fourth cambered surface which are tangent to the rolling balls are arranged on the inner wall of the star-shaped sleeve.

Eight of the channels are provided.

The short shaft is axially provided with a long hole, and the short shaft is circumferentially provided with an oil hole communicated with the long hole.

The oilhole is equipped with two.

The utility model has the advantages that: the utility model provides a portable universal joint of lightweight, convenient to detach changes, and when the star cover became invalid, the joint can used repeatedly, improves the reuse rate of product.

Fig. 2 is a schematic partial sectional view of an embodiment of the present invention.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings: portable universal joint of lightweight, including casing 1, casing 1 is including dismantling sleeve pipe 12 and the joint 11 of connection, the intraductal star cover 122 that is equipped with channel 121 and is used for the jackshaft to pack into of cover still includes holder 3, be equipped with spin 31 on the holder, the spin with the star cover cooperatees, the spin with the channel cooperatees, be equipped with minor axis 111 on the joint. Convenient to detach changes, when the star cover became invalid, connects and to use repeatedly, according to the motorcycle type that does not use, also can change different and connect, makes its product reach dual-purpose effect, improves the reuse rate of product.

In this embodiment, the sleeve and the fitting are connected by a fastener 33, as shown. May be a bolt, screw, etc.

In this embodiment, a sealing ring 34 is provided between the opposite surfaces of the sleeve and the joint, as shown. Preventing leakage.

In this embodiment, as shown, the channel includes a first arc 1211 and a second arc 1212 that are tangent to the ball, and the inner wall of the spider sleeve is provided with a third arc 1221 and a fourth arc 1222 that are tangent to the ball. The rolling ball is in point contact with the 2 points of the star-shaped sleeve and the 2 points of the channel, which has the advantages of reducing contact stress, storing lubricating grease at the bottom of the rolling ball due to the 2 points of contact, achieving the effect of lubricating and cooling and prolonging the service life of the product.

In this embodiment, eight channels are provided, as shown. Through analysis, the steel balls bear less stress and longer fatigue life as more steel balls are, and the design of the 8 ball tracks is beneficial to saving the loading space, so that the whole vehicle weight is reduced, the oil-saving effect is achieved, and the service life of the product can be prolonged.

In the present embodiment, as shown in the drawing, the short shaft is axially provided with a long hole 3222, and the short shaft is circumferentially provided with an oil hole 3223 communicating with the long hole. Oil in the gearbox can flow into bearing shelves department through slot hole and oilhole, not only reaches the effect of lowering the temperature and lubrication, can effectively prevent to lead to the high emergence veneer phenomenon of temperature because of the rotational speed is too fast, leads to the effect of product inefficacy, has also reduced the quality of product self moreover, reaches the effect of oil consumption reduction.

In this embodiment, as shown in the drawing, there are two oil holes.

In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
