Suspension Vibration Isolation Device of Permanent Magnetic Adsorption Mecanum Wheel Vehicle

Abstract

The invention provides a suspension vibration isolation device for a permanent magnet adsorption type Mecanum wheel vehicle, which includes a flexible unit and a horizontal mechanism. One end of the flexible unit is arranged on the top platform of the magnet fixing seat, and the other end of the flexible unit is movably connected to the frame fixing seat. , the bottom of the magnet fixing seat is connected with a permanent magnet one, the frame fixing seat is connected to the boss of the bearing seat through a horizontal mechanism, the bearing seat and the magnet fixing seat are respectively connected to the servo motor one through bolts, and the servo motor one is connected to the Mecanum wheel one through the axle ; It can meet the adsorption stability and motion stability of the Mecanum wheel, ensure the contact and pressure between the Mecanum and the surface of the magnetic material, ensure the distance and parallelism between the permanent magnet and the adsorption surface, and make the adsorption effect more stable. At the same time, the shock isolation unit can realize The vibration isolation in the upper and lower directions can meet the vibration isolation effect of the adsorption surface of the robot installed with the suspension system at various angles.

Description

technical field [0001] The invention relates to a suspension vibration isolation device of a permanent magnet adsorption type Mecanum wheel vehicle. Background technique [0002] The Mecanum Wheel (Mecanum Wheel) is an all-round mobile wheel, invented by the Swiss Bengt Lion in 1973, so it is also called the Lion wheel, and he works for Mecanum AB. The feature of this wheel is that on the basis of the traditional wheel, a number of small rollers that can rotate freely are installed on the rim along the direction of 45° with the axis, so that when the wheel rolls, the small rollers will produce direction-finding motion. Through the combined use and control of the mecanum wheels, the car body can be moved and rotated in any direction within the motion plane. [0003] In 1975, Lion obtained the U.S. patent (Patent No. 3,746,112, "Directionally Stable Self Propelled Vehicle"). In 1980, the U.S. Navy bought the patent and developed it for military applications. After the patent ...

Problems solved by technology

Many universities in the world, including my country, have also carried out research on the application and control of Mecanum wheels, but most of them focus on the application research on mobile robots, and few products have been formed.

[0005] The Institute of Robotics of Harbin Institute of Technology and other units in China have conducted research on omni-directional mobile robots based on Mecanum wheels, but there are few papers on the research on Mecanum wheels in China
