Problems solved by technology
[0003] At present, in the field of robot drive or automobile wheel drive, drive technologies mainly include pneumatic drive, thermal drive, micro-motor drive, intelligent material drive, energy field drive and traditional engine drive, etc., but there are still many problems, such as energy The consumption is high and the steering system is inflexible. If you want to make the steering more flexible, you need more investment. Therefore, it is very necessary to design a robot platform driving mechanism with flexible steering without increasing the cost.

The invention belongs to the technical field of robot platform driving and particularly relates to a hydraulic-drive-based robot platform driving wheel, comprising a motor, a hydraulic pump, a driving wheel, a driving wheel cavity, a driving spindle, a universal ball, a driving ball housing, a rotary piston, an outer frame, and an inner frame, wherein a high-pressure liquid pumped out by the hydraulic pump enters the driving wheel cavity and drives the driving wheel to rotate, the driving wheel drives the driving spindle to rotate, and in this way, the hydraulic pump transmits power to the wheel through the driving spindle such that the wheel rotates; the outer frame and the inner frame are mounted on the driving ball housing, and the rotary piston is mounted on the universal ball. Through the cooperation of the outer frame and the inner frame and the cooperation of the rotary piston and the inner frame in the hydraulic-drive-based robot platform driving wheel, the universal ball may rotate at any angle; by using the hydraulic-drive-based robot platform driving wheel for driving, it is possible to provide power for a wheel, it is also possible for turn the wheel, and damping function is also provided; the hydraulic-drive-based robot platform driving wheel is simple in structure and very practical.
Description
[0001] Technical field [0002] The invention belongs to the technical field of robot platform driving, and in particular relates to a driving wheel of a robot platform based on hydraulic drive. Background technique [0003] At present, in the field of robot drive or automobile wheel drive, drive technologies mainly include pneumatic drive, thermal drive, micro-motor drive, intelligent material drive, energy field drive and traditional engine drive, etc., but there are still many problems, such as energy The consumption is high and the steering system is inflexible. If you want to make the steering more flexible, you need more investment. Therefore, it is very necessary to design a robot platform driving mechanism with flexible steering without increasing the cost. [0004] The present invention designs a robot platform drive wheel based on hydraulic drive to solve the above problems. Contents of the invention [0005] In order to solve the above-mentioned defects in the pr...
