Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] A shafting structure for an industrial vehicle of the present invention is a shafting structure for a mecanum wheel (but not limited to a mecanum wheel), comprising an inner hub 1, an outer hub 2, a reducer mounting flange 3, Coupling 4, bearing 6, lock nut 7, reducer 8; also includes seal ring 5, also includes motor 9.

[0018] The inner hub is hollow, with a flange on the right side inside, the inner hub is sleeved on the outside of the coupling 2, and the coupling 2 is located in the hollow space of the inner hub on the left side of the flange of the inner hub.

[0019] The outer hub is located outside the inner hub; and the inner hub 1 and the outer hub 2 are connected by a pair of bearings 6, so that the inner and outer hubs can rotate relatively, ensuring the radial bearing capacity of the shafting.

[0020] The inner wheel hub outer ring on the...

Abstract

The invention discloses an industrial car axle structure, belongs to the technical field of cars and solves problems that existing industrial car axles are relatively long in size, the overall transmission accuracy is lowered and the like. The axle structure mainly comprises an inner hub, an outer hub, a coupling, bearings, a lock nut and a speed reducer, wherein the inner hub is hollow, and the coupling is located inside hollow space of the inner hub on the left side of a flange of the inner hub. The mounting clearance can be reduced while the connection relation is met, and the motion accuracy is increased; and the structure can be particularly applied to Mecanum wheels.

Description

technical field [0001] The invention belongs to the technical field of vehicles and relates to a shaft system connecting a mecanum wheel and a vehicle body in a vehicle. Background technique [0002] The traditional shaft system is generally composed of motor, reducer, coupling, outer hub, hub shaft, etc. This structure makes the shaft system larger in size and higher in cost. In the traditional structure, the coupling is connected outside the hub shaft, which is a pure series structure, resulting in a longer shafting size; in the traditional structure, when the coupling and the hub shaft are connected by a flat key, the shafting After running for a long time, the flat key is easy to produce gaps due to wear, which makes the overall transmission accuracy lower; in addition, because the structure of the flange connected to the reducer is more complicated, the production cost is higher. Contents of the invention [0003] The technical problem solved by the present invention...
