Referring to fig. 1-2, an axle 100 of a vehicle according to an embodiment of the present invention is described, wherein the axle 100 is used to solve the problems of complicated assembly process of a driven bevel gear of an existing axle, resulting in high installation difficulty and high production cost.

As shown in fig. 1-2, the present invention provides an axle 100 for a vehicle, including a housing 10, a driven disc 20, and a spacing pad 40. The housing 10 forms a chamber therein, and the housing 10 can effectively protect the inner parts of the chamber, so that the inner parts of the chamber are supported and more durable.

As shown in fig. 1, a driven plate 20 is disposed in the chamber, and the driven plate 20 is used to transmit power, which can be transmitted with a driving gear on a transmission shaft. A limit washer 40 is axially abutted between the driven plate 20 and the inner peripheral wall of the chamber. It should be noted that, the tapered roller bearing is generally adopted at one side of driven plate to traditional axle, and in the utility model discloses in, use spacing liner 40 to replace current tapered roller bearing, can reduce the step of tapered roller bearing adjustment play like this to can reduce the assembly degree of difficulty, thereby improve assembly efficiency. In addition, the position limiting pad 40 is simple in structure and convenient to install.

Preferably, the position limiting pad 40 is made of nylon, and the position limiting pad 40 made of nylon has the characteristics of good heat insulation performance and low hardness, so that the sliding friction force caused by the rotation of the gear can be effectively reduced, and the service life of the driven disc 20 can be prolonged.

Alternatively, as shown in fig. 1, the driven disk 20 includes a disk body 21 and a driven gear 22, and the driven gear 22 is fixed to the disk body 21. One axial end of the disk body 21 is rigidly connected to the driven gear 22 by a bolt.

Further, as shown in fig. 1, the limit pad 40 is provided on a back tooth surface of the disc body 21, i.e., a side of the disc body 21 facing away from the driven gear 22. The inner peripheral wall of the chamber of the axle 100 ensures an assembly spacing for assembling the spacing pad 40, and the spacing pad 40 is installed between the inner peripheral wall of the chamber of the axle 100 and the back flank of the disc 21. In the direction of the axial force generated by the disc body 21, the limiting pad 40 can bear the axial load brought by the disc body 21, and the limiting pad 40 arranged in this way can enable the axle 100 to be simpler and more stable in structure.

As shown in fig. 2, the limiting pad 40 is provided with an oil groove 41 through which lubricating oil flows. The oil groove 41 is provided with lubricating oil, and the lubricating oil can play a role in lubricating and cooling. In the non-conventional output axle 100, there is sliding friction between the limit pads 40 and the disc 21. Therefore, the oil groove 41 can reduce the frictional heat caused by the sliding friction of the position limiting packing 40.

As shown in fig. 2, the oil grooves 41 on the position limiting gasket 40 are plural, the plural oil grooves 41 include radial oil grooves 411 extending radially and/or circumferential oil grooves 412 extending circumferentially, and the radial oil grooves 411 and/or the circumferential oil grooves 412 are circumferentially spaced. It is understood that the plurality of oil grooves 41 may include only the radial oil groove 411, only the circumferential oil groove 412, and may also include both the radial oil groove 411 and the circumferential oil groove 412, and the radial oil groove 411 and the circumferential oil groove 412 are provided at intervals in the circumferential direction. As shown in fig. 2, the provision of the plurality of oil grooves 41 not only allows the provision of lubricating oil but also reduces the frictional area between the limit pad 40 and the driven plate 20, thereby further reducing the heat generated by friction.

Specifically, as shown in fig. 2, between two radial oil grooves 411, the position limiting gasket 40 is provided with two circumferential oil grooves 412 arranged at radial intervals. The radial oil groove 411 and the circumferential oil groove 412 which are arranged in this way are matched, so that heat generated by friction of the limiting gasket 40 can be effectively reduced, and the service life of the axle 100 can be effectively prolonged.

In some examples of the present invention, the limiting pad 40 is provided with a first limiting portion, the inner peripheral wall of the chamber is provided with a second limiting portion, and the first limiting portion and the second limiting portion are circumferentially matched in a limiting manner.

The first and second limit portions are fitted to each other, and the limit pad 40 can be prevented from rotating due to sliding friction, so that the stability of the axle 100 can be ensured.

As shown in fig. 2, the first position-limiting portion includes a plurality of circumferentially spaced position-limiting protrusions 413, and the second position-limiting portion includes a plurality of circumferentially spaced position-limiting grooves or position-limiting steps, and the protrusions are fitted in the position-limiting grooves or the position-limiting steps. The plurality of limiting matches arranged in this way can effectively limit the circumferential rotation angle of the limiting gasket 40 and prevent the limiting gasket 40 from rotating, so that effective sliding friction can be performed between the disc body 21 and the limiting gasket 40.

As shown in fig. 1, the inner peripheral wall of the chamber is further provided with a first limiting surface 50, the driven gear 22 is provided with a second limiting surface 51 on the corresponding axial side surface of the tooth portion, and the first limiting surface 50 and the second limiting surface 51 are axially opposite to each other. When the driven gear 22 rotates, the first limiting surface 50 and the second limiting surface 51 are axially matched, so that the axial movement of the driven gear 22 can be reduced, and the stability of the axle 100 can be ensured.

As shown in fig. 1, the axle 100 may further include a bearing shell 30, with the bearing shell 30 disposed within the cavity. The bearing bush 30 is fitted over the driven plate 20 and also radially abuts against the inner circumferential wall of the chamber. The bearing bush 30 is relatively smooth, can bear a high load, has a low rotation speed, and is sleeved on the disc body 21 to bear an acting force generated when the driven disc 20 rotates, so that the driven disc 20 stably operates, and friction loss generated when the driven gear 22 rotates can be reduced.

The axle 100 is more stable and reliable due to the structure that the axis of the bearing bush 30 is collinear with the axis of the driven disc 20, and the other end of the disc body 21 is matched with the bearing bush 30 to perform the centering function when the driven gear 22 idles. And, the axle bush 30 simple structure, simple to operate uses axle bush 30 can also reduce cost and installation degree of difficulty.

Specifically, the driven disk 20 is hollow in the interior, and the axle 100 further includes an axle-shaft-connector 60 and an engagement device 70, the axle-shaft-connector 60 and the engagement device 70 being provided in the interior of the driven disk 20, the engagement device 70 being for selectively engaging the axle-shaft-connector 60 and the driven disk 20.
