[0018] The present utility model will be described in more detail below in conjunction with the drawings and embodiments.

[0019] The present utility model discloses an integrated crawler drive motor. As shown in Figures 1 to 4 , it includes a fixed shaft 1. A stator is fixed on the fixed shaft 1. A rotor is arranged outside the stator. An inner wheel ring 2 is fixed outside the rotor. A star-shaped hub 3 is formed outside the inner wheel ring 2. The star-shaped hub 3 includes a plurality of radial support arms 30 and an outer wheel ring 31. One end of the radial support arm 30 is integrally formed with the outside of the inner wheel ring 2, and the other end of the radial support arm 30 is integrally formed with the inside of the outer wheel ring 31. Axial support arms 32 symmetrically extending to the left and right are evenly distributed on the outer wheel ring 31.

[0020] In the above structure, the fixed shaft 1 can be assembled and connected to preset fixed components such as a support plate and a vehicle frame. The stator on the fixed shaft 1 and the rotor sleeved outside it form the basic structure of the motor. At the same time, an inner rim 2 is fixed outside the rotor. The inner rim 2 not only serves as the motor housing but also conducts power. The star-shaped hub 3 is assembled inside the track. Based on the clamping and matching relationship between the outer rim 31 and the axial support arm 32 and the inner components of the track, when the track drive motor operates, it can drive the track to rotate. In practical applications, auxiliary wheels can be installed inside the track together with the track drive motor of the present invention, thereby realizing the walking drive function. Compared with the prior art, the track drive motor of the present invention can be directly matched with the track, which is not only convenient for assembly but also does not require an additional transmission mechanism, saving application costs and avoiding energy loss.

[0021] In order to play a covering and protecting role at both left and right ends, in combination with Figure 1 and Figure 2 as shown, this embodiment includes a left end plate 4 and a right end plate 5. Both ends of the fixed shaft 1 pass through the left end plate 4 and the right end plate 5 respectively.

[0022] The left end plate 4 and the right end plate 5 in this embodiment are fixed components. Therefore, in this embodiment, both the left end plate 4 and the right end plate 5 are fixedly connected to the stator.

[0023] Please refer to Figure 1 and Figure 2 , the width of the inner rim 2 is greater than the widths of the stator and the rotor. Among them, the larger width of the inner rim 2 can accommodate the stator and the rotor inside the inner rim 2, so that the inner rim 2 also has the function of a motor housing.

[0024] As a preferred method, the edges of the left end plate 4 and the edges of the right end plate 5 are respectively arranged adjacent to the two side edges of the inner rim 2. Among them, on the basis of adjacent edges, a narrow gap is formed between the left end edge of the left end plate 4 and the left end edge of the inner rim 2, and a narrow gap is formed between the right end edge of the right end plate 5 and the right end edge of the inner rim 2. In practical applications, it is best to set components such as rubber bands and brushes that can block the narrow gaps at the edges of the inner rim 2, so as to play a role in dust and dirt prevention and ensure the reliable rotation of the inner rim 2.

[0025] In order to ensure reliable transmission of the driving force, in this embodiment, the radial support arm 30 is a trapezoidal support arm that gradually narrows outward along the radius of the inner rim 2. This trapezoidal radial support arm 30 has sufficient mechanical strength.

[0026] Please refer to Figure 3, in this embodiment, the axial support arm 32 extends in a direction perpendicular to the outer rim 31. In addition, in some other embodiments of the present invention, the two symmetric axial support arms 32 may also be distributed in a "herringbone" shape. Correspondingly, components such as stoppers or card slots corresponding to the axial support arms 32 can be provided on the crawler belt.

[0027] In order to reliably fix the left end plate 4 and the right end plate 5, in this embodiment, left and right locking rings 6 and 7 are respectively fixed to both ends of the fixed shaft 1, and the left locking ring 6 and the right locking ring 7 are respectively arranged outside the left end plate 4 and the right end plate 5.

[0028] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements or improvements made within the technical scope of the present invention shall be included within the scope protected by the present invention.
