An unmanned vehicle hub motor high mobility driving control system

Abstract

The invention belongs to the field of vehicle engineering and discloses an unmanned vehicle hub motor high-mobility drive and control system. The first three bridges are single longitudinal arm bridges, and the fourth bridge is a double wishbone bridge. The single longitudinal arm bridge includes tire Wheel rim assembly, trailing arm, trailing arm mounting bracket, oil-pneumatic spring and hub motor; the double wishbone bridge includes upper cross arm, lower cross arm, steering knuckle, hub motor and steering gear, and the present invention utilizes distributed drive hub motor Matched with oil-pneumatic spring independent suspension, the vehicle realizes the ability to pass through ultra-high geometric obstacles and the ability to maneuver on high-speed off-road roads. The system adopts the full-point drive mode, which has high power density, small space, and stable and reliable operation; the system components are modularized, with good interchangeability, low cost, and easy maintenance.

Description

technical field [0001] The invention relates to a light-duty ultra-high motor vehicle hub motor driving driving control system, which belongs to the field of vehicle engineering. Background technique [0002] Light ultra-high motor vehicles put forward strict requirements for their passing ability: the average cross-country speed is 30 km / h; the maximum climbing angle is not less than 32°; the maximum rolling slope is not less than 20°; Less than 1.2 meters; the vertical obstacle height is not less than 0.6 meters; it has the ability to pass on soft ground, etc.; the ultra-high passing ability requirements put forward new requirements for the vehicle driving system: super large suspension stroke; with vehicle attitude adjustment function Large lateral stiffness; flexible steering capability; super large drive torque output; super large ground area, etc., most of the four-axle off-road vehicles in the prior art are heavy off-road vehicles, and the four-axle is applied to ligh...
