Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings.

Example one

A kind of thrust wheel, the whole of the spoke 10 takes the form of the conical ring-type and its outer mouth edge and one side end of the rim 20 extend the spin-flow transition to connect, the inner mouth edge of the spoke 10 is along the middle part that is set up in the axle sleeve 30 axial direction of the wheel and both weld as an organic whole. As shown in the attached figure 2, the wheel body of the thrust wheel is formed by welding and connecting two parts, and has simple structure and convenient processing. The section of the spoke 10 and the section of the rim 20 which are integrally formed by spinning are integrally in a 7 shape, the rim 20 forms a transverse rod of the spoke and is coaxially arranged with the wheel hub 30, and the longitudinal rod of the spoke 10 can reliably transmit load.

When the wheel is assembled, as shown in fig. 5, the two heavy wheels are respectively connected to two ends of the wheel shaft through bearings in a rotating mode, the ends with large calibers of the spokes 10 are arranged oppositely, the free ends of the rim 20 are arranged oppositely, the load borne by the wheel shaft is transmitted to the rim 20 through the bearings, the wheel shaft sleeve 30 and the spokes 10, and the transmission path of the load is reliable. In addition, in the present embodiment, the axle is rotatably connected to the axle sleeve 30 through two bearings, and in order to reliably position the bearings, a boss 31 protruding inward in the radial direction of the axle sleeve 30 is provided at a middle position in the axial direction of the axle sleeve, and an end surface of the outer ring of the bearing is abutted against and matched with the boss 31 in the assembled state. In order to ensure the stability of the assembly structure, the inner opening of the spoke 10 in the embodiment coincides with the projection of the boss 31 on the axle sleeve 30 in the axial direction, so that the spoke 10 applies a load on the axle sleeve 30 at the boss 31, the uniform stress of the two bearings can be ensured, and the service life of the thrust wheel can be prolonged.

In this embodiment, the spoke 10 is a frustum-shaped plate, the middle section of the spoke is a conical ring 11, the inner end of the conical ring 11 is connected with the inner ring 12, and the outer end of the conical ring 11 is connected with the outer ring 13.

The inner ring 12 is perpendicular to the axial direction of the axle sleeve 30, which is convenient for welding operation and can improve the quality of welding connection.

As shown in fig. 5, in the assembled state, the thrust wheels are pressed against the track and cooperate with stop elements of the track, which are located between the two thrust wheels and which will press against the spokes 10 when the crawler is turning or when the ground is uneven. In order to improve the strength of the spoke 10 and ensure the bearing capacity of the thrust wheel, as shown in fig. 2, the outer ring 13 of the spoke 10 and the conical ring 11 are arranged in an included angle manner, an angle opening of the included angle points to the free end of the rim 20, and an angle vertex at an included angle between the outer ring 13 and the conical ring 11 is positioned outside the end surface of the rim 20. In practical application, the limiting element of the crawler supports against the vertex of the angle between the outer ring 13 and the conical ring 11, so that the bearing capacity of the thrust wheel can be enhanced, and the spoke 10 is prevented from being damaged due to excessive extrusion of load. In the embodiment, the spinning piece is low in molding difficulty, material is saved, the production period is short, and the cost is lower.

As shown in FIG. 2, in order to ensure the structural strength of the wheel body and facilitate the processing and forming, the outer ring 13 has a length greater than the length of the inner ring 12 in the radial direction of the rim 20 and less than 1/3 of the length of the conical ring 11 in the radial direction of the rim 20, i.e. 1/3d ₁₁ >d ₁₃ >d ₁₂ And the included angle between the outer ring 13 and the end face of the rim 20 is more than 5 degrees and less than or equal to 30 degrees.

Furthermore, spoke 10 is connected with the inner side end face of rim 20 along the extending spinning transition, and the outer end of rim 20 is provided with a spinning forming built-in flanging 21. As shown in fig. 2, one end of rim 20 is connected to spoke 10, the other end is in a free overhanging shape, and a built-in flange 21 is disposed at the free end of the rim located at the outer side, and the built-in flange 21 can effectively maintain the outer end shape of rim 20, thereby ensuring the reliable attachment of the outer ring surface of rim 20 to the track, and further ensuring the reliable transmission of load.

In order to further reduce the self weight of the wheel body, the conical ring 11 is further provided with lightening holes 111. The lightening holes 111 can also allow muddy water and gravel to pass through the thrust wheel, so that the stress on two sides of the thrust wheel is more balanced, and the damage of uneven stress on a wheel shaft or a bearing caused by the deflection of a wheel body of the thrust wheel is avoided.

Example two

The difference between this embodiment and the first embodiment is that the inner side surface of the outer ring 13 of the spoke 10 is provided with a rib 14, and the outer peripheral surface of the rib 14 is arranged flush with the outer surface of the rim 20. The height of the projection of the rib 14 in the axial direction of the outer ring 13 is greater than the thickness of the plate body of the outer ring 13, and the dimension of the rib 14 in the radial direction of the outer ring 13 is greater than the thickness of the rim 20. Obviously, the protruding height of the axial direction of the protruding muscle 14, radial thickness are great, and the wearability is better, and the damage to the wheel spoke 10, the rim 20 junction is less after wearing out, compares with embodiment one, can further promote the bearing capacity and the life of thrust wheel, but its processing degree of difficulty is great, and the cost is higher.
