Problems solved by technology

[0002] The existing wheel sets of in-field transportation devices generally use track-type wheel sets or bridge-type drive wheel sets. The track wheel sets can only move on the pre-laid track and can only walk in a straight line, which takes up a lot of space and has poor maneuverability; The steering wheel set is divided into a steering wheel set and a driving wheel set. The steering wheel set completes the steering within a certain angle range through a specific mechanical structure, and combines with the driving wheel set used to drive the walking to complete the steering movement of the overall transportation device, but the movement Low precision, unable to realize small space operations such as in-situ rotation and in-situ lateral translation

Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the technical scheme of the present invention is described in further detail:

[0014] See attached Figure 1~3 As shown, this kind of wheel set integrating drive and steering is characterized in that:

[0015] The center of the polyurethane drive wheel 15 hub is provided with a shaft hole with a keyway I, which is connected to the drive shaft 21 through the key I22 installed in the keyway I. The inner ring of the tapered roller bearing I24 installed on the drive shaft 21 is in contact with the outer ring of the tapered roller bearing I24. Positioning, the shaft shoulder at the other end of the drive shaft 21 is fixed to the inner ring of the tapered roller bearing II19, the outer ring of the tapered roller bearing II19 is installed in the mounting hole of the drive wheel mount 11, and the belt mounted on the drive wheel mount 11 The right end cover 18 with a central hole is axially positioned, the drive sh...

Abstract

The invention provides a wheel set integrating the driving function and the steering function. The wheel set integrates a dual-direction omni-bearing steering mechanism and a walking driving mechanism, integration of a dual-direction omni-bearing steering mechanism is improved, modular design of the driving wheel set is achieved, all the parts are installed on a base, the integration level is high, the installation size is reduced, integral installation and integral detachment are achieved, and installation, maintenance and the like of the driving device are convenient; multiple driving wheel sets are jointly used or a single wheel set and auxiliary supporting wheel sets are jointly used, and small-space transport adjustment such as heavy-load and intermediate-range transport, small turning radius and even in-situ rotation, transverse movement and the like of transport equipment can be achieved.

Description

technical field [0001] The invention relates to a wheel set integrating driving and steering, relates to the design of a heavy-duty omnidirectional driving device, and belongs to the technical field of transportation and vehicles. Background technique [0002] The existing wheel sets of in-field transportation devices generally use track-type wheel sets or bridge-type drive wheel sets. The track wheel sets can only move on the pre-laid track and can only walk in a straight line, which takes up a lot of space and has poor maneuverability; The steering wheel set is divided into a steering wheel set and a driving wheel set. The steering wheel set completes the steering within a certain angle range through a specific mechanical structure, and combines with the driving wheel set used to drive the walking to complete the steering movement of the overall transportation device, but the movement The precision is low, and small space operations such as in-situ rotation and in-situ lat...
