Technical Field
[0001] This utility model relates to the field of tracked mobile platform technology, specifically to the track drive wheels of a tracked mobile platform. Background Technology
[0002] Tracked mobile platforms are devices capable of mobile operations in complex terrains and harsh environments. They mainly consist of a walking system, a drive system, a control system, a suspension system, and a load-bearing system, and have strong handling capabilities and adaptability to various application scenarios and operational needs.
[0003] In existing tracked mobile platforms, the drive wheels often directly contact the tracks, resulting in significant track wear. Furthermore, when the drive wheels drive the tracks, they directly contact and compress the tracks, and the weight of the drive wheels directly affects the tracks, causing them to be easily damaged and have a short service life. Utility Model Content
[0004] The purpose of this invention is to provide a track drive wheel for a tracked mobile platform. The inner and outer drive steel wheels are wrapped with rubber rings. The rubber rings contact the track, which can reduce track wear, reduce the weight of the inner and outer drive steel wheels, and extend the service life of the track, thus solving the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] The track drive wheel of the tracked mobile platform includes a mobile platform, a drive shaft is provided on the mobile platform, an inner drive steel wheel and an outer drive steel wheel are mounted on the drive shaft, and the outer rings of the inner drive steel wheel and the outer drive steel wheel are both wrapped with rubber rings. The inner drive steel wheel and the outer drive steel wheel contact the track through the rubber rings. The drive shaft is also equipped with a first drive gear and a second drive gear, and the first drive gear and the second drive gear mesh with a rack block provided on the inner surface of the track.
[0007] Preferably, the mobile platform is equipped with a drive motor, the output shaft of the drive motor is mounted with a first sprocket, the first sprocket is connected to a second sprocket via a chain, the second sprocket is mounted on a drive shaft, and the drive shaft is mounted on the outside of the mobile platform via bearings.
[0008] Preferably, the first drive gear and the second drive gear are located between the inner drive steel wheel and the outer drive steel wheel.
[0009] Preferably, the mobile platform is provided with support brackets on both sides, the upper end of the support bracket is provided with a guide wheel for guiding the track, and the lower end of the support bracket is provided with a driven steel wheel for driving the track.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] When the drive motor of this invention is started, the drive shaft rotates, which in turn drives the inner drive steel wheel, the outer drive steel wheel, the first drive gear, and the second drive gear to rotate. This causes the track to rotate under the driving and guiding action of the inner drive steel wheel, the outer drive steel wheel, the guide wheel, and the driven steel wheel.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] To address the technical problem of existing tracked mobile platforms where the drive wheels directly contact the tracks, and the drive wheels drive and compress the tracks, resulting in the weight of the drive wheels directly impacting the tracks and causing easy track damage and short service life, please refer to [link to relevant documentation]. Figures 1-4 This embodiment provides the following technical solution:
[0021] The tracked mobile platform includes a mobile platform 1, on which a drive shaft 2 is mounted; wherein, a drive motor is installed inside the mobile platform 1, and a first sprocket is mounted on the output shaft of the drive motor. The first sprocket is connected to a second sprocket via a chain, and the second sprocket is mounted on the drive shaft 2. The drive shaft 2 is mounted on the outside of the mobile platform 1 via bearings.
[0022] Specifically, when the drive motor starts, the output shaft of the drive motor drives the first sprocket to rotate. Since the first sprocket is connected to the second sprocket through a chain, the first sprocket can drive the chain and the second sprocket to rotate during the rotation, thus causing the drive shaft 2 to rotate.
[0023] An inner drive steel wheel 21 and an outer drive steel wheel 22 are mounted on the drive shaft 2. The outer rings of the inner drive steel wheel 21 and the outer drive steel wheel 22 are both wrapped with rubber rings 3. The inner drive steel wheel 21 and the outer drive steel wheel 22 both contact the track 4 through the rubber rings 3.
[0024] Specifically, by having the rubber ring 3 contact the track 4, wear on the track 4 can be reduced, the weight of the inner drive steel wheel 21 and the outer drive steel wheel 22 can be reduced, and the service life of the track 4 can be extended.
[0025] The drive shaft 2 is also equipped with a first drive gear 23 and a second drive gear 24, both of which mesh with the rack block 41 provided on the inner surface of the track 4; wherein, the first drive gear 23 and the second drive gear 24 are located between the inner drive steel wheel 21 and the outer drive steel wheel 22.
[0026] Specifically, during the rotation of the drive shaft 2, the inner drive steel wheel 21, the outer drive steel wheel 22, the first drive gear 23, and the second drive gear 24 can be driven to rotate. Since the first drive gear 23 and the second drive gear 24 are both engaged with the rack block 41 provided on the inner surface of the track 4, the first drive gear 23 and the second drive gear 24 can drive the track 4 to rotate under the driving and guiding action of the inner drive steel wheel 21, the outer drive steel wheel 22, the guide wheel 51, and the driven steel wheel 52.
[0027] It should be noted that support brackets 5 are provided on both sides of the mobile platform 1. The upper end of the support bracket 5 is provided with a guide wheel 51 for guiding the track 4, and the lower end of the support bracket 5 is provided with a driven steel wheel 52 for driving the track 4.
[0028] The guide wheel 51 and the driven steel wheel 52 are both located inside the track 4. The guide wheel 51 contacts the inner surface of the upper end of the track 4. The outer ring of the driven steel wheel 52 is wrapped with a rubber ring 3, and the driven steel wheel 52 contacts the track 4 through the rubber ring 3.
[0029] Specifically, when the drive motor starts, its output shaft drives the first sprocket to rotate. Since the first sprocket is connected to the second sprocket via a chain, its rotation drives the chain and the second sprocket to rotate as well, causing the drive shaft 2 to rotate. During this rotation, the drive shaft 2 drives the inner drive steel wheel 21, the outer drive steel wheel 22, the first drive gear 23, and the second drive gear 24 to rotate. Since both the first drive gear 23 and the second drive gear 24 mesh with the rack block 41 on the inner surface of the track 4, their rotation drives the track 4 to rotate under the guidance of the inner drive steel wheel 21, the outer drive steel wheel 22, the guide wheel 51, and the driven steel wheel 52. Furthermore, the outer rings of the inner drive steel wheel 21 and the outer drive steel wheel 22 are both wrapped with rubber rings 3. These rubber rings 3 contact the track 4, reducing wear on the track 4, lightening the weight of the inner drive steel wheel 21 and the outer drive steel wheel 22, and extending the service life of the track 4.
