Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

Referring to fig. 1, an axle 100 of a vehicle according to an embodiment of the present invention is described below, where the axle 100 is used to solve the problem that the electromagnet structure of the existing axle occupies a large space and the structural arrangement is not compact. The vehicle may be an all terrain vehicle.

As shown in fig. 1, the axle 100 of the embodiment of the present invention includes: a housing, an electromagnet 20 and a bearing 30. The housing effectively protects the internal components of the housing, making the axle 100 more robust and durable, and the internal components of the housing supported.

Specifically, a chamber is formed inside the housing, the electromagnet 20 is disposed in the chamber, and the electromagnet 20 is fixed on the inner circumferential wall of the chamber. Wherein, the housing may include a housing and an end cap 10, the end cap 10 is fixed on one axial side of the housing, for example, the right side, and the electromagnet 20 is disposed on the inner peripheral wall of the end cap 10.

As shown in fig. 1, a shaft hole 21 is formed inside the electromagnet 20, the bearing 30 is mounted in the shaft hole 21, and the shaft hole 21 is provided to penetrate in the axial direction, that is, in the left-right direction shown in fig. 1. The bearing 30 may be used to support an axle shaft, and in particular, the bearing 30 is used to support a connector of the axle shaft. By arranging the bearing 30 in the shaft hole 21 of the electromagnet 20, the occupied space of the axial direction of the components in the axle 100 can be reduced, so that the axial length of the axle 100 can be reduced, the overall structure of the axle 100 can be more compact, and the reliability is better.

In addition, because the bearing 30 is arranged in the shaft hole 21 of the electromagnet 20, the installation reliability is good, and the bearing and the end cover can be integrally installed on the inner peripheral wall of the end cover 10 after being assembled, so that the assembly difficulty of the axle 100 can be reduced to at least a certain degree.

In order to increase the load carrying capacity of the electromagnet 20, the wall thickness of the electromagnet 20 may be increased within a certain range, and the magnetic strength of the electromagnet 20 may be increased.

In some examples of the present invention, the bearing 30 includes an outer ring, an inner ring, a rolling member, and a holder, the holder is disposed between the outer ring and the inner ring, the rolling member is disposed on the holder, and the rolling member can roll with respect to the inner ring and the outer ring. Wherein, the bearing 30 can be a deep groove ball bearing, and the effect of the deep groove ball bearing supporting half shaft is better.

Wherein the outer ring is fixed on the inner peripheral wall of the shaft hole 21. By positioning the outer ring of the bearing 30 on the inner circumferential wall of the shaft hole 21, the electromagnet 20 can effectively fix and limit the outer ring, so that the bearing 30 can effectively support the axle shaft.

Further, the outer ring may be interference-fitted on the inner circumferential wall of the shaft hole 21. The outer ring of the bearing 30 is arranged on the inner peripheral wall of the shaft hole 21 in an interference fit mode, so that the outer ring and the electromagnet 20 are fixed reliably, the structural reliability of the axle 100 can be improved, and the assembly difficulty of the bearing 30 and the electromagnet 20 can be reduced. During assembly, the bearing 30 may be press-fitted into the shaft hole 21.

As shown in fig. 1, the electromagnet 20 is further provided with a stop ring 22 at an end of the shaft hole 21, and the stop ring 22 stops at an axial end of the outer ring, which is axially outward, i.e., to the right as viewed in fig. 1. The stop ring 22 prevents the bearing 30 from moving axially during operation, and improves the stability of the bearing 30 in the axle hole 21, thereby further stabilizing the axle 100. The radial extension of the stop ring 22 may be greater than or equal to the radial dimension of the outer ring of the bearing 30, so that the stop ring 22 may completely stop the outer ring at the axial outer side of the outer ring, thereby better ensuring the stability of the outer ring.

Alternatively, the outer peripheral wall of the electromagnet 20 may be an interference fit on the inner peripheral wall of the chamber. The inner peripheral wall of the chamber may be formed with mounting holes in which the outer peripheral wall of the electromagnet 20 is interference fitted. The axle 100 that so sets up has many places interference fit, can improve the rigidity of axle 100 effectively to the pine between bearing 30 and the electro-magnet 20 can be solved effectively to interference fit's mode and take off the problem, thereby can improve the stability of axle 100, can further improve the reliability of axle 100.

Further, the axes of the outer circumferential wall and the inner circumferential wall of the electromagnet 20 are collinear. The arrangement enables the bearing 30 to operate smoothly, and enables the connecting head mounted in the bearing 30 to operate smoothly, so that the operational reliability of the axle 100 can be improved, and the bearing 30 is convenient to disassemble, assemble and maintain.

As shown in fig. 1, the axially inner end surface of the electromagnet 20 is a friction use surface 23, and the surface area of the friction use surface 23 is smaller than the surface area of the axially outer end surface 25 of the electromagnet 20, that is, the axially inner end surface, that is, the left end surface of the electromagnet 20. When the vehicle runs, the electromagnet 20 and the left moving component generate sliding friction, so the friction using surface 23 of the electromagnet 20 is reduced in a reasonable range, the friction contact area of the electromagnet 20 is reduced, the heat generated by the friction using surface 23 of the electromagnet 20 during sliding friction can be reduced, and the abrasion of the electromagnet 20 can be effectively reduced.

Specifically, as shown in fig. 1, an outer annular groove 26 is formed on the outer periphery of the friction use surface 23. By providing the outer annular groove 26, the surface area of the friction use surface 23 can be reduced at least to some extent, and wear of the electromagnet 20 can be reduced.

As shown in fig. 1, an inner annular groove 27 is formed on the inner periphery of the friction use surface 23, and the inner diameter of the inner annular groove 27 is larger than the outer diameter of the bearing 30. That is, an inner annular groove 27 having an inner diameter larger than an outer diameter of the bearing 30 is provided on an inner periphery of the friction use surface 23. This can further reduce the friction-use surface 23 of the electromagnet 20, thereby further reducing the frictional contact area and reducing the wear of the electromagnet 20.
