Description

Technical Field

[0001] This utility model belongs to the technical field of small agricultural machinery equipment accessories, and specifically relates to a track drive component. Background Technology

[0002] In the existing technology, track drive is often used in micro tillers, root and tuber crop harvesters, and straw crop harvesters. The existing tracks are equipped with grip teeth on the outer side and force application holes on the track. The drive wheel or transfer wheel that cooperates with it is equipped with protrusions or force application teeth that match the force application holes. When the drive wheel or transfer wheel rotates, it drives the track to rotate around and move in place.

[0003] The technical problems with the current track and drive wheel or transfer wheel assembly are as follows: 1. Insufficient axial meshing force between the track and the drive wheel or transfer wheel. The assembly structure only achieves radial matching of the force-applying hole and the protrusion or force-applying tooth. In the axial direction, the track is prone to disengagement, causing drive failure of the equipment; 2. When the track is driven, the driving force is mainly achieved through the matching combination structure of the force-applying hole and the protrusion or force-applying tooth. After years of use or in poor road conditions, the force-applying hole will wear down, causing the hole diameter to increase. This increase in hole diameter will reduce the driving efficiency and seriously affect the driving efficiency.

[0004] In view of the shortcomings of existing technology, it is very necessary for the research and development and manufacturing units of micro or small agricultural machinery to improve the structure of the existing drive track. The purpose is to increase the contact points of the drive track in the axial and radial directions, which can improve the driving stability in both directions. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, this utility model proposes a track drive assembly, which, by setting a blocking component on the inner side of the track and improving the drive wheel or moving wheel, can exert force simultaneously in the radial and axial directions, thereby improving drive stability and drive efficiency.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A track drive assembly includes a track and wheels, wherein the track is provided with outer gripping teeth and engagement holes, and the inner side of the track is also provided with an inner protrusion.

[0008] The wheel is provided with meshing teeth that engage with meshing holes; the inner protrusion is provided on the side of the wheel and is used for axial blocking and restraint of the wheel.

[0009] The inner protrusions are arranged in at least two rows on both sides of the wheel, and the wheel is constrained in the middle by the two rows of inner protrusions, thus achieving axial constraint on the wheel on both sides.

[0010] The inner protrusions are a plurality of spaced protrusions, and a drive gap is provided between every two inner protrusions; the side of the wheel is provided with a plurality of wheel protrusions, and the wheel protrusions cooperate with the drive gaps to achieve force transmission or swing constraint.

[0011] The wheel protrusion is provided with a reinforcing part, which connects the wheel protrusion to the wheel body, thereby improving the overall strength of the wheel protrusion.

[0012] The wheel has a hollow structure, which can improve the overall strength of the wheel and reduce its overall weight.

[0013] This utility model has the following beneficial effects: It discloses a track drive assembly, including a track and a wheel. The track is provided with outer gripping teeth and meshing holes, and the inner side of the track is also provided with an inner protrusion. The wheel is provided with meshing teeth that engage with the meshing holes. The inner protrusion is located on the side of the wheel, serving as an axial restraint for the wheel. The inner protrusion can be arranged in two rows on both sides of the wheel, constraining the wheel in the middle through the two rows of inner protrusions, thus achieving axial restraint on the wheel simultaneously on one or both sides. This utility model provides dual protection for the wheel and track in both the axial and radial directions, effectively improving the transmission stability of driving force and preventing track slippage. It makes the mechanical operation of the machine using this track drive assembly more stable, making it an ideal track drive assembly. Attached Figure Description

[0020] The present invention will be further described below through embodiments. Those skilled in the art can refer to the embodiments for implementation, and can also make technical improvements and innovations based on the existing technical solutions.

[0021] Example 1: A track drive assembly includes a track 1 and a wheel 2. The track 1 is provided with outer grip teeth 11 and engagement holes 12, and an inner protrusion 13 is also provided on the inner side of the track; the outer grip teeth 11 are tapered, with their top cross-section smaller than their bottom cross-section; the engagement holes 12 are also tapered, with their inner cross-section larger than their outer cross-section, and the inner cross-section is the side closer to the wheel 2.

[0022] The wheel 2 has meshing teeth 23 on its outer diameter that engage with meshing holes 12 on the track 1. The inner protrusion 13 is located on the side of the wheel 2 and serves as an axial restraint. While those skilled in the art may use single-sided restraint, this device can also achieve double-sided restraint. In this embodiment, the inner protrusion 13 is arranged in at least two rows, with the two rows located on opposite sides of the wheel body 22. The two rows of inner protrusions 13 restrain the wheel 2 in the middle, simultaneously achieving axial restraint on both sides of the wheel.

[0023] When setting the inner protrusions 13, there are several inner protrusions 13 arranged at intervals, and a driving gap 14 is provided between every two inner protrusions 13; several wheel protrusions 24 are respectively provided on both sides of the wheel body 22, and the wheel protrusions 24 cooperate with the driving gaps 14 to realize force transmission or swing constraint. When the wheel 2 rotates, the meshing teeth 23 on its outer diameter cooperate with the meshing holes 12 on the track 1, and at the same time, the wheel protrusions 24 enter into the driving gaps 14 and press against the inner protrusions 13 when rotating. When the wheel 2 is a driving wheel, it can be driven by the wheel protrusions 24 pressing against and applying force to the inner protrusions 13 on the track 1; when the wheel 2 is a driven wheel, the inner protrusions 13 on the track 1 pressing against and applying force to the wheel protrusions 24 realizes the reverse driving or constraint of the track 1 on the driven wheel.

[0024] The wheel 2 has a bearing or keyway at its axle 21 for fixing the drive shaft or driven shaft. The outer part of the axle 21 is a plate-shaped wheel body 22 with several weight-reducing holes 26 or other hollow structures. The hollow structure can improve the overall strength of the wheel 2 and reduce its overall weight.

[0025] This invention provides wheel protrusions 24 cast or welded on the left and right sides of the wheel body 22, and also provides reinforcing parts 25 around the wheel protrusions 24. The reinforcing parts 25 connect the wheel protrusions 24 to the wheel body 22, thereby improving the overall strength of the wheel protrusions 24.

[0026] In summary, this utility model constrains the wheel 2 in the middle by means of two rows of inner protrusions 13, and simultaneously achieves axial constraint on the wheel 2 on one or both sides. This provides dual protection for the wheel 2 and the track 1 in both the axial and radial directions, effectively improving the transmission stability of driving force and preventing track slippage, thus making the mechanical operation of the track drive assembly more stable. Furthermore, when the wheel protrusion 24 rotates, it enters the drive gap 14 and presses against the inner protrusions 13, thereby achieving auxiliary drive and improving the driving stability of the wheel 2 and the track.
