Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] The present invention provides a speed differential steering unmanned motor vehicle, which includes six sets of rocker suspension systems, two sets of motor drive systems, six wheels 2 and a vehicle body 14, and three wheels are evenly arranged on both sides of the vehicle body 14 2. Each wheel 2 is connected with a rocker suspension system, and the wheels on one side share a drive system, which can independently control the position of the rocker arm 1 of each wheel suspension, and the speed and torque of the wheel 2 on one side. Wherein, the rocker arm suspension system includes a rocker arm 1 , a rocker arm motor reducer 5 , an electromagnetic brake 6 , a rocker arm motor 7 , a friction damper 8 and a torsion bar 9 . The motor drive system includes three wheel reducers 3 , three elbow internal transmission mechanisms 4 , a disc brake 10 , a moto...

Abstract

The invention discloses a differential-steering unmanned motor vehicle. The differential-steering unmanned motor vehicle adopts an in-elbow drive technology, and a driving motor is put in a vehicle body. Compared with an adopted hub motor scheme, the size and weight requirements for the motor is reduced, the motor selection and adapting difficulty is greatly reduced, meanwhile a high-rotating-speed and high-power-density motor can be selected, higher power can be provided under the requirement that the vehicle weight is limited, and the maneuvering performance, especially the cross-country maneuvering performance of the vehicle is greatly improved. In addition, the motor and other large-mass parts are arranged inside a compartment, the unsprung mass of a suspension system is reduced, the response capability of a suspension is improved, meanwhile the moving load of the suspension is decreased, and the cross-country performance can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicles, in particular to a speed differential steering unmanned vehicle. Background technique [0002] With the development of information technology, computer technology and control technology, unmanned driving technology has reached a milestone in the progress. Unmanned vehicles on roads are approaching the practical stage. Unmanned vehicles can replace or assist human driving and manipulation, which can greatly reduce the labor intensity of the driver, enhance the control ability of the vehicle, and improve driving safety at the same time. The application of unmanned driving technology to non-road vehicles can not only replace people to complete some dangerous driving tasks, but also improve the off-road maneuverability of vehicles in non-road driving. In the case of unmanned driving, the physiological limit of the human body is no longer involved, and the off-road driving vehicle can give...
