Omni-directional wheel device and electric drive transfer vehicle with same

Abstract

The invention discloses an omni-directional wheel device. The omni-directional wheel device comprises an omni-directional wheel mounting plate, a steering reducer, a steering motor, a vehicle wheel fixing support and the like, wherein the steering motor and the steering reducer are arranged above the mounting plate, the steering reducer penetrates through the mounting plate and is connected with apinion, the pinion is meshed with outer teeth of a turntable bearing, an inner ring of the turntable bearing is fixedly connected with the vehicle wheel fixing support, a walking motor is connected to a walking reducer, the walking reducer drives a synchronous pulley to rotate so as to drive a small wheel I to rotate to enable a vehicle wheel to walk. The invention further discloses the omni-directional transfer vehicle with the omni-directional wheel device.

Description

technical field [0001] The invention belongs to the technical field of spacecraft and component handling. Specifically, the invention relates to a transfer device. The transfer device is mainly used in the transfer of large-scale heavy-duty spacecraft workshops, and has the functions of forward, backward, translation and in-situ rotation. The way to achieve "zero radius" transfer. Background technique [0002] The precise transfer of large-sized and heavy-weight spacecraft has always been a problem that plagues the final assembly of spacecraft. The problem of transshipment in a small space needs to be solved. It needs to solve the problem to minimize the turning radius and accurately locate the required parking position. The traditional wheeled transfer can no longer meet the transfer needs of large spacecraft, and the existing air cushion and other transfer methods that can realize the "zero-radius" transfer function also have the disadvantage of not being able to accurat...

Problems solved by technology

However, the use of air cushion technology requires a high demand for fixed facilities in the plant. For example, it must have an air source that meets the requirements, and there are many transfer accessories for air cushion technology. Especially when transferring, it is necessary to drag the air pipe to supply air for the air cushion. However, due to the limitation of air pipe pressure , the trachea cannot be extended indefinitely, which results in frequent replacement of the trachea during long-distance (especially between factory buildings) transfers

Moreover, in view of the technical characteristics of air cushion transfer, whether it is smooth ground or passing through the groove at the door of the factory building, it is necessary to deal with the gaps, and the preparation before use is more complicated.
