Independent drive and independent turning robot secondary adjusting hydraulic moving platform

Abstract

An independent drive and independent turning robot secondary adjusting hydraulic moving platform mainly comprises wheels, a platform body, an electromagnetic brake, a secondary adjusting hydraulic drive device and the like. Through adjustment of the displacement of secondary elements on the left side or the right side of the platform, the rotation speed and the rotation angle of the wheels on theleft side or the right side of the platform are adjusted, and platform turning is achieved. The four secondary elements drive the four wheels through speed reducers correspondingly, the secondary elements are adjusted to be in a hydraulic motor or hydraulic pump work condition, and the platform is driven to move or the braking kinetic energy and ramp gravity energy of the platform are recycled andstored in an energy accumulator for starting, accelerating and climbing motions of the moving platform. The independent drive and independent turning robot secondary adjusting hydraulic moving platform is suitable for working in the open air, high-speed and large-load work conditions, and the moving platform is high in bearing and high in traction capability; and energy recycling and reutilizingcan be achieved, and the installed power of the moving platform is greatly reduced.

Description

Technical field [0001] The invention relates to a robot mobile platform, in particular to an independent driving and independent steering robot secondary adjustment hydraulic mobile platform. Background technique [0002] The mobile platform is the carrier of the robot. At present, the mobile platform usually adopts electric drive mode. For example, the foreign Meidensha and the domestic Siasun mobile platforms are all driven by electric motors. The mobile platform has good operation and control performance, but most of them are only suitable for indoor environments. It has poor general applicability, low moving speed, insufficient maneuverability and insufficient load-bearing towing capacity. It is not suitable for high-speed and heavy-load working conditions. [0003] Hydraulic transmission has been widely used in the engineering field because of its smooth transmission, convenient speed regulation, large power-to-mass ratio, and strong load-carrying capacity, and has become one ...

Problems solved by technology

[0002] The mobile platform is the carrier of the robot. At present, the mobile platform usually adopts electric drive mode. For example, the foreign Meidensha and the domestic Xinsong mobile platforms are all driven by motors. The mobile platform has better manipulation and control performance, but most of them are only suitable for indoor environments. Work, the universality is poor, and the moving speed is low, the mobility and off-road performance and the load-carrying traction capacity are insufficient, and it is not suitable for high-speed and heavy-load working conditions
