Problems solved by technology

Since no consideration is given to installing the drive mechanism on the joint wheel, this design limits the mobility of the omni wheel
[0005] For example, the patent application "omnidirectional wheel" with the application number 201120121753.X, as far as a single wheel is concerned, it can realize the front and rear rolling of the wheel, but it cannot realize the left and right autonomous movement of the wheel

Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0022] The omni-directional wheel capable of omnidirectional movement of the present invention comprises hub 1, joint wheel 2, joint wheel driving mechanism, wheel cover 11 and other components.

[0023] The two hubs 1 (rolling forward and backward) are coaxially connected to the left and right, and there are a plurality of joint wheels 2 (short rollers that rotate left and right) evenly distributed on the upper circumference of each hub 1, and the joints on the left and right hubs 1 The wheels 2 are dislocated relative to each other, and a plurality of worm support frames 10 uniformly distributed on the circumference are horizontally arranged on the outer edge of each wheel hub 1, and the left and right wheel covers 11 are respectively installed and connected on the end faces of the left and right worm support frames ...

Abstract

The invention discloses an omnidirectional wheel that can move in all directions, including left and right wheel hubs that are coaxially fixed and rotated forward and backward, joint wheels that rotate left and right are evenly distributed on the circumference of each wheel hub, and the positions of the joint wheels on the left and right wheel hubs are: It is wrong, and it also includes the left and right joint wheel drive mechanisms that are symmetrically arranged on both sides of the left and right hubs to drive the rotation of each joint wheel on the corresponding hub. The joint wheel drive mechanism includes a worm gear transmission pair and a bevel gear transmission pair. The worm gear of the pair is set coaxially with the hub, and the double-headed worms of the worm gear transmission pair are evenly distributed on the circumference and aligned with each segment wheel on the corresponding hub, and the rotation shafts of each segment wheel and the alignment worm shaft are connected by corresponding transmission mechanisms. The driven large bevel gear of the bevel gear transmission pair is coaxially fixedly connected with the worm gear, and the small bevel gear of the bevel gear transmission pair is arranged axially symmetrically and is respectively connected with the output shaft at the corresponding end of the pitch wheel drive motor arranged between the two. The invention can realize the omnidirectional movement of the omnidirectional wheel through the combined movement of the wheel hub and the joint wheel.

Description

technical field [0001] The invention relates to a road running mechanism, in particular to an omnidirectional wheel capable of omnidirectional movement. Background technique [0002] Wheeled walking mechanism is a common road running mechanism, which can be used in transportation tools such as bicycles and automobiles. [0003] The omnidirectional wheel is the basic component of the wheeled walking mechanism. Through mutual drive and cooperation, it can realize all-round movement of front, rear, left and right. It has the characteristics of simple structure and flexible rotation. It is widely used in trolleys, transfer and transportation Machines, trucks, suitcases, etc. [0004] Existing omnidirectional wheel great majority is that driving motor is installed on the axle sleeve of omnidirectional wheel, and the bull wheel that rotates before and after is used as driving wheel, and the small joint wheel that rolls left and right on omnidirectional wheel is used as driven whe...
