Description

Integrated track drive motor

[0001] This application is based on and claims priority to Chinese Patent Application No. 202421622940.X, filed on July 10, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to power devices, and more particularly to an integrated track drive motor. Background Technology

[0003] Tracked vehicles are generally used to travel in environments such as snow and sand. Existing tracked vehicles generally have the drive mechanism located inside the frame, and then use the front and rear drive wheels to drive the tracks. This structural layout has a complex transmission method, involves many components, and has a lot of energy loss during transmission. At the same time, the assembly process is also relatively complicated, resulting in high application costs. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide an integrated track drive motor that can be directly matched with the track, is easy to assemble, and saves costs, in order to address the shortcomings of the existing technology.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution.

[0006] An integrated track drive motor includes a fixed shaft, a stator fixed on the fixed shaft, a rotor on the outer side of the stator, an inner wheel ring fixed on the outer side of the rotor, a star-shaped hub formed on the outer side of the inner wheel ring, the star-shaped hub including multiple radial arms and an outer wheel ring, one end of each radial arm being integrally formed with the outer side of the inner wheel ring, the other end of each radial arm being integrally formed with the inner side of the outer wheel ring, and axial arms extending symmetrically to the left and right sides being evenly distributed on the outer wheel ring.

[0007] In some embodiments, the fixed axis includes a left end plate and a right end plate, with the two ends of the fixed axis passing through the left end plate and the right end plate, respectively.

[0008] In some embodiments, both the left end plate and the right end plate are fixedly connected to the stator.

[0009] In some embodiments, the width of the inner rim is greater than the width of the stator and the rotor.

[0010] In some embodiments, the edges of the left end plate and the right end plate are respectively disposed adjacent to the two side edges of the inner rim.

[0011] In some embodiments, the radial support arm is a trapezoidal support arm that gradually narrows outward along the radius of the inner rim.

[0012] In some embodiments, the axial support arm extends in a direction perpendicular to the outer rim.

[0013] In some embodiments, a left locking ring and a right locking ring are fixed at both ends of the fixed shaft, respectively.

[0014] In some embodiments, the left locking ring and the right locking ring are respectively disposed on the outer side of the left end plate and the right end plate.

[0015] In the integrated track drive motor disclosed in this application, the fixed shaft can be assembled and connected with preset support plates, frames, and other fixed components. The stator on the fixed shaft and the rotor mounted on its outer side form the basic structure of the motor. At the same time, an inner wheel ring is fixed on the outer side of the rotor. The inner wheel ring serves as both the motor housing and the power transmission. The star-shaped hub is assembled on the inner side of the track. Based on the snap-fit ​​relationship between the outer wheel ring and the axial support arm and the inner side components of the track, the track drive motor can drive the track to rotate when it is running. In practical applications, auxiliary wheels can be installed on the inner side of the track along with the track drive motor of this application to achieve the walking drive function. Compared with the prior art, the track drive motor of this application can be directly matched with the track, which is not only convenient for assembly, but also eliminates the need for a separate transmission mechanism, saving application costs and avoiding energy loss.

[0020] The present application will now be described in more detail with reference to the accompanying drawings and embodiments.

[0021] This application discloses an integrated track drive motor, as shown in Figures 1 to 4. It includes a fixed shaft 1, a stator fixed on the fixed shaft 1, a rotor on the outer side of the stator, an inner wheel rim 2 fixed on the outer side of the rotor, and a star-shaped hub 3 formed on the outer side of the inner wheel rim 2. The star-shaped hub 3 includes a plurality of radial support arms 30 and an outer wheel rim 31. One end of the radial support arm 30 is integrally formed with the outer side of the inner wheel rim 2, and the other end of the radial support arm 30 is integrally formed with the inner side of the outer wheel rim 31. Axial support arms 32 extending symmetrically to the left and right sides are evenly distributed on the outer wheel rim 31.

[0022] In the above structure, the fixed shaft 1 can be assembled and connected with preset support plates, frames and other fixed components. The stator on the fixed shaft 1 and the rotor mounted on its outer side form the basic structure of the motor. At the same time, an inner wheel rim 2 is fixed on the outer side of the rotor. The inner wheel rim 2 serves as both the motor housing and the power transmission. The star-shaped hub 3 is assembled on the inner side of the track. Based on the snap-fit ​​relationship between the outer wheel rim 31 and the axial support arm 32 and the inner side components of the track, when the track drive motor is running, it can drive the track to rotate. In practical applications, auxiliary wheels and the track drive motor described in this application can be installed on the inner side of the track to achieve the walking drive function. Compared with the prior art, the track drive motor of this application can be directly matched with the track, which is not only convenient for assembly, but also eliminates the need for a separate transmission mechanism, saving application costs and avoiding energy loss.

[0023] In order to provide coverage and protection at both ends, as shown in Figures 1 and 2, this embodiment includes a left end plate 4 and a right end plate 5, with the two ends of the fixed shaft 1 passing through the left end plate 4 and the right end plate 5 respectively.

[0024] In this embodiment, the left end plate 4 and the right end plate 5 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.

[0025] Please refer to Figures 1 and 2. The width of the inner rim 2 is greater than the width of the stator and the rotor. The larger width of the inner rim 2 allows the stator and the rotor to be accommodated within it, thus enabling the inner rim 2 to also function as a motor housing.

[0026] As a preferred embodiment, the edges of the left end plate 4 and the right end plate 5 are respectively arranged adjacent to the two side edges of the inner rim 2. Specifically, while maintaining this edge proximity, a narrow gap is formed between the left end plate 4 and the left edge of the inner rim 2, and a narrow gap is formed between the right end plate 5 and the right edge of the inner rim 2. In practical applications, it is best to provide components such as rubber strips or brushes at the edges of the inner rim 2 to cover the narrow gaps, thereby preventing dust and dirt accumulation while ensuring reliable rotation of the inner rim 2.

[0027] To ensure reliable transmission of 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 wheel rim 2. This trapezoidal radial support arm 30 has sufficient mechanical strength.

[0028] Please refer to Figure 3. In this embodiment, the axial support arm 32 extends in a direction perpendicular to the outer wheel rim 31. In addition, in some other embodiments of this application, the two symmetrical axial support arms 32 may be arranged in a "V" shape. Correspondingly, blocks or slots corresponding to the axial support arms 32 may be provided on the track.

[0029] In order to reliably fix the left end plate 4 and the right end plate 5, in this embodiment, a left locking ring 6 and a right locking ring 7 are fixed at both ends of the fixed shaft 1, respectively, and the left locking ring 6 and the right locking ring 7 are respectively located on the outside of the left end plate 4 and the right end plate 5.

[0030] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, or improvements made within the technical scope of this application should be included within the scope of protection of this application.
