Abstract

The invention relates a power transmission device, in particular to a power transmission device for an omni-directional mobile platform. The power transmission device comprises an internal side omni-directional wheel driven by a gearbox, wherein an external side omni-directional wheel is arranged on the external side of the internal side omni-directional wheel; the external side omni-directional wheel comprises a hub; the hub is structured to be rotationally connected with a supporting frame fixed on a frame; a bracket seat is fixedly arranged on the external side of the internal side omni-directional wheel at an axis; a connecting shaft is rotationally connected with the bracket seat; axle holes with mutually orthogonal axes are are formed in the two ends of the connecting shaft, respectively; one end of the connecting shaft is connected with the connecting shaft through a first pin shaft; the other end of the connecting shaft is rotationally connected with a shaft coupling seat; an axle hole allowing the shaft coupling seat to be connected with the connecting shaft through a second pin shaft is formed in one end of the shaft coupling seat; a blind hole allowing the hub to sleeve is formed in the other end of the shaft coupling seat; and the hub is fixedly connected with the shaft coupling seat through a first fastening piece arranged in a radial direction of the shaft coupling seat. Through the adoption of the power transmission device for the omni-directional mobile platform, provided by the invention, a problem that it is unable to normally run because the internal side omni-directional wheel is suspended can be avoided.

Description

technical field

[0001] The present invention relates to a power transmission device, in particular to a power transmission device for an omnidirectional mobile platform, and more specifically to a power transmission device used in the front double wheel arrangement structure of an omnidirectional mobile platform. transmission device. Background technique

[0002] Omnidirectional refers to a driving method that can directly move in any direction within a 2D plane. The omni-directional wheel is a mechanism that evenly distributes several rollers on the outer circular end surface of a hub, which is the basis for realizing omni-directional walking. Omni-directional wheels have the advantages of wear resistance, impact resistance, and anti-static. However, with the emergence of omni-directional mobile platforms, the demand and requirements for omni-directional mobile platforms are increasing. Among them, the requirement to increase the load capacity of the platform is the first...

Examples

Embodiment 1

[0020] This embodiment provides a power transmission device for an omnidirectional mobile platform, which can be used in the arrangement structure of the front double wheels and the front double wheels of the omnidirectional mobile platform.

[0021] Such as image 3 As shown, a power transmission device for an omnidirectional mobile platform in this embodiment includes an inner omnidirectional wheel 3 and an outer omnidirectional wheel 12 . Wherein, the power of the inner omni-directional wheel 3 is input by the power source 1 through the gearbox 2, and the inner omni-directional wheel 3 is provided with a support seat 21 through the connecting bolt 4, and the support seat 21 is rotatably connected with a connecting shaft 19. The outer omnidirectional wheel 12 includes a hub 10 configured to be rotatably connected to the support frame 7 fixed on the vehicle frame 14 . The two ends of the connecting shaft 19 are respectively constructed with a shaft hole whose axes are orthog...
