Embedded type straight gear reversing Mecanum wheel

Abstract

An embedded type straight gear reversing Mecanum wheel comprises a Mecanum wheel body, wherein a supporting system is disposed on the interior of the Mecanum wheel body and is rotatably connected withthe Mecanum wheel body. An internal gear ring flange is disposed on the inner wall of the Mecanum wheel body. A power input shaft is disposed on the supporting system and is located in the gyration center of the Mecanum wheel body. A reversing free central gear and a homodromous free central gear are disposed on the power input shaft. A reverse mechanism is linked on the power input shaft. A reversing driving gear, a first homodromous driving gear and a second homodromous driving gear are rotatably connected on the supporting system. The reversing driving gear is engaged with the reversing free central gear and the internal gear ring flange. The first homodromous driving gear is respectively engaged with the homodromous free central gear and the second homodromous driving gear which is engaged with the internal gear ring flange.

Description

technical field [0001] The invention belongs to the field of vehicle engineering, and relates to an omnidirectional mobile wheel, in particular to a built-in straight-tooth reversible mecanum wheel. At the same time, it also belongs to the field of robotics and automation, involving all-round planar mobile robot technology. Background technique [0002] Mecanum Wheel (Mecanum Wheel) is a kind of all-round mobile wheel. It was invented by Swiss Bengt Lion in 1973, so it is also called Lion Wheel, and he works for Mecanum AB Company. The feature of this wheel is that on the basis of the traditional wheel, several small rollers that can rotate freely are installed on the rim along the direction of 45° with the axis, so that when the wheel rolls, the small rollers will produce direction-finding motion. Through the combined use and control of the mecanum wheels, the car body can be moved and rotated in any direction within the motion plane. [0003] In 1975, Lion obtained the U...

AI Technical Summary

Problems solved by technology

[0017] The present invention addresses the problems of the existing mecanum-wheel-based omnidirectional mobile robot with complex drive structure and control system, which can only be driven by motors and cannot effectively utilize the workability of the drive motors, and cannot use high-efficiency power sources such as internal combustion engines, etc.
