Abstract

The invention discloses a full steering moving chassis, and relates to the technical field of chassis. The chassis comprises a base plate which is provided with a plurality of omni-directional moving units, wherein each omni-directional moving unit comprises at least one wheel, a steering support frame which is connected with a wheel shaft of the wheel, a steering drive wheel which is disposed the steering support frame in a sleeving manner, a vertical shaft which is mounted in the steering support frame, a walking drive wheel which is fixed on the vertical shaft, a driving bevel gear which is arranged at the lower end of the vertical shaft, and a driven bevel gear which is disposed on the wheel shaft in a sleeving manner and engages with the driving bevel gear; the walking drive wheels and the steering drive wheels of the omni-directional moving units are respectively connected through a first transmission belt and a second transmission belt; and a walking drive motor and a steering drive motor are mounted on the base plate, an output shaft of the walking drive motor is connected with the first transmission belt in a transmission manner, and an output shaft of the steering drive motor is connected with the steering supporting frame of one of the omni-directional moving units in a transmission manner. Compared with the prior art, the chassis disclosed by the invention has the advantages of light weight, high flexibility and good controllability.

Description

technical field [0001] The invention relates to the technical field of chassis, in particular to a full-steering mobile chassis suitable for vehicles or mobile robots. Background technique [0002] At present, the main forms of vehicle chassis or mobile robot chassis on the market are wheeled and crawler. The wheel-type chassis is low in cost and easy to control its steering, while the crawler-type chassis has a large load-bearing area and is more suitable for use on harsh roads. But these two ways all can not realize the full steering function of 360 degrees when turning. At present, the full steering of the general robot mechanism is to add a steering motor to each steering shaft. This chassis includes a base plate and a plurality of wheels arranged under the base plate. Each wheel is connected to its own steering drive motor and travel drive motor. , the chassis of this structure has the following disadvantages: 1. The number of motors required is large, which makes the...
