An unmanned vehicle wheel hub motor driving control system

Abstract

The invention belongs to the field of vehicle engineering, and discloses an unmanned vehicle hub motor driving driving control system. The first and second bridges are single trailing arm bridges, and the third and fourth bridges are double wishbone bridges. The single trailing arm bridges include tires 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...

[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 light-duty high-mobility vehicles, which cannot meet light-duty high-mobility vehicles The performance requirements of the vehicle, such as 200620158767.8 discloses a kind of oil-pneumatic spring independent suspension and a heavy-duty vehicle using the suspension. The structure of the independent suspension is heavy and cannot be applied to light-duty high-mobility vehicles, and cannot meet the requirements of light-duty motor vehicles
