[0002] In order to enable the loader to obtain sufficient torque, a wheel-side reducer needs to be installed on the wheel side. In the wheel-side reducer, the wheel-side internal gear meshes with the planetary gear. Each planetary gear is installed on a planetary carrier fixed to the wheel hub. The planetary gear is driven by a half-shaft. The high-speed rotation of the planetary gear will be converted into the low-speed rotation of the planetary carrier. The planetary carrier and the wheel hub are fixed, thereby realizing low-speed and high-torque rotation of the wheel hub.

[0030] The present invention will be further described below in conjunction with the accompanying drawings:

[0031] like Figure 1 — Figure 6 As described above, this embodiment provides a wheel-side internal gear of a loader with an emergency braking function, which is meshed with a plurality of planetary gears 5. The wheel-side internal gear includes a wheel body 1, a staggered internal gear ring 2, a plurality of braking devices 3 and a plurality of suction devices 4. Each planetary gear 5 is meshed with the staggered internal gear ring 2. Each planetary gear 5 is rotatably mounted on a planetary carrier 7. Each planetary gear 5 is meshed with a half shaft 6 for transmission. The staggered internal gear ring 2 is installed in the wheel body 1 with an interference fit. In this way, when the staggered internal gear ring 2 and the wheel body 1 are staggered with each other, energy is absorbed, thereby generating a braking effect, thereby controlling the wheel body 1. The driving device 3 is installed between the planetary wheels 5, the braking device 3 slides along the planetary wheels 5, the braking device 3 slides along the offset internal gear ring 2, and the attraction devices 4 are installed on the outside of the wheel body 1. When emergency braking is required, the attraction devices 4 attract the braking device 3, and the attraction devices 4 attract the braking device 3 to clamp the tooth surface of the offset internal gear ring 2. When the attraction devices 4 clamp the tooth surface of the offset internal gear ring 2, the planetary wheels 5 squeeze the braking device 3, thereby limiting the continued movement of the planetary wheels 5, and the offset internal gear ring 2 and the wheel body 1 offset each other to absorb energy.

[0032] The wheel body 1 includes a spline section 11 , which is used to fix the wheel body 1 circumferentially. When in use, the wheel body 1 does not rotate, and the planetary gear 5 meshes with the staggered internal gear ring 2 to drive the planetary carrier 7 to rotate around the center line of the wheel body 1 .

[0033] The wheel body 1 includes a plurality of sliding grooves 12, each of which is provided with an energy absorbing cone 121 at both ends of each sliding groove 12, and the adjacent energy absorbing cones 121 are arranged in pairs, and the sliding groove 12 is connected with a mounting groove 122, and the staggered inner gear ring 2 slides along the sliding groove 12 and then presses the energy absorbing cone 121, and a brake column 21 is provided on the outer side of the staggered inner gear ring 2, and the brake column 21 is respectively slidably connected with the sliding groove 12, the energy absorbing cone 121 and the mounting groove 122, and the side of the energy absorbing cone 121 is provided with a rubber buffer pad When the brake column 21 slides to contact the energy absorbing cone 121, the brake column 21 presses the buffer pad, thereby further absorbing energy and producing a braking effect. When installing the offset internal gear ring 2, the brake column 21 is installed into the sliding groove 12 along the installation groove 122, and the offset internal gear ring 2 and the wheel body 1 are installed using a conventional interference fit installation method. The wheel body 1 can be heated to expand it for easy installation, and the offset internal gear ring 2 can also be cooled to shrink it for easy installation. This is a prior art and will not be described in detail here.

[0034] Each braking device 3 includes a braking slider 31 and a clamping slider 32. The clamping slider 32 slides along the braking slider 31. The braking slider 31 is installed between each planetary gear 5. Each braking slider 31 slides along the tooth top circle of the planetary gear 5. The braking slider 31 slides along the tooth top circle of the offset internal gear ring 2. The suction device 4 attracts the clamping slider 32 to clamp the tooth surface of the offset internal gear ring 2. The end of the braking slider 31 is adapted to the contour of the offset internal gear ring 2. When the suction device 4 attracts, the braking slider 31 slides out from the offset internal gear ring 2 and then pushes against the gear ring of the offset internal gear ring 2, so that the relative position between the braking slider 31 and the offset internal gear ring 2 is fixed, so that the offset internal gear ring 2 and the wheel body 1 are mutually offset to absorb energy.

[0035] A return spring is also installed on the clamping slider 32, and the return spring drives the clamping slider to move away from the attracting magnet, thereby releasing the brake.

[0036] Each attraction device 4 is an electromagnet, which is convenient for rapid control.
