Description

Technical Field

[0001] The utility model relates to the technical field of load-bearing wheel devices, in particular to a new type of load-bearing wheel used for a skid loader. Background Art

[0002] Most of the load-bearing wheels of the existing skid steer loaders on the market include a wheel body and an axle. The wheel body and the axle are usually simply matched and installed for connection, that is, the wheel body and the axle are connected by direct contact and sliding friction to achieve the purpose of relative rotation, and the friction between the two can only be reduced as much as possible by sufficient lubricating oil.

[0003] At present, the new skid loader load-bearing wheel of the existing utility model has a wheel body and axle pivotally connected by a bearing, that is, rolling friction is generated between the wheel body and the axle through the bearing. Compared with the existing technology, it breaks through the structural form of direct sliding connection between the wheel body and the axle of the traditional load-bearing wheel, overcomes the sliding friction between the wheel body and the axle of the traditional load-bearing wheel, and then causes the defects of unsmooth rolling and poor stability of the load-bearing wheel, making the load-bearing rolling of the load-bearing wheel more flexible, smooth, stable and practical.

[0004] For example, a new type of skid loader load-bearing wheel disclosed in the authorization number CN202847857U includes a wheel body and a wheel axle, and the wheel body and the wheel axle are pivotally connected together through a bearing. However, in the process of the movement of the wheel body, the wheel axle and the wheel body are prone to axial sliding movement due to the sliding of the bearing, and the anti-skid performance of the wheel body is relatively low.

[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that during the movement of the wheel body, the wheel axle and the wheel body are prone to axial sliding movement due to bearing sliding, and the anti-slip performance of the wheel body is low. Therefore, it is necessary to improve the existing technology. Utility Model Content
