Driving and steering device for unmanned vehicle

Abstract

The invention provides a driving and steering device for an unmanned vehicle. The driving and steering device for the unmanned vehicle comprises a driving wheel frame and a driving wheel assembly. The driving wheel frame is connected with a frame through a shock absorption mechanism, composite idler wheels are arranged on the two sides of the driving wheel frame, rail grooves are formed in the two side edges of the frame, and the composite idler wheels roll up and down in the rail grooves. A shell body of a gearbox is fixedly connected with a connecting cover which is supported against the inner portion of a cavity hole of the driving wheel frame through a conical bearing, the connecting cover is fixedly connected with an upper pressing cover and can rotate inside the cavity hole, meanwhile, a big gear wheel is arranged on the outer circumference of the connecting cover, and the big gear wheel is meshed with a small gear wheel arranged on an output shaft of a steering motor. An electromagnetic detection device is arranged on the driving wheel frame. The driving and steering device for the unmanned vehicle is simple and compact in structure and convenient to manufacture, install and adjust, the ground adhesive force of the driving wheel can be adjusted, and the condition that the driving wheel slips due to the insufficient adhesive force is avoided. The driving and steering device for the unmanned vehicle is smooth in running, good in shock absorption and free of the stuck phenomenon. The service life of electric wires is effectively prolonged, and the safety performance of the vehicle is improved. The steering is accurately controlled.

Description

technical field [0001] The invention belongs to the technical field of unmanned vehicles, and in particular relates to a driving and steering device for unmanned vehicles. Background technique [0002] Modern society is an information society. Artificial intelligence and automatic control penetrate into all aspects of daily life. The progress of information technology and electronic technology provides a good foundation for the development of intelligent transportation. Intelligent transportation has become the direction of future industrial vehicle development. Traditional industries The vehicle is driven by a driver, and the driving status of the vehicle is greatly affected by human subjective factors. Therefore, due to the irregular operation and misoperation of the driver, urban road traffic congestion, reduced road traffic flow, and frequent major traffic accidents are caused. It is becoming more and more serious, which brings great inconvenience and harm to people's pr...

[0002] Modern society is an information society. Artificial intelligence and automatic control penetrate into all aspects of daily life. The progress of information technology and electronic technology provides a good foundation for the development of intelligent transportation. Intelligent transportation has become the direction of future industrial vehicle development. Traditional industries The vehicle is driven by a driver, and the driving status of the vehicle is greatly affected by human subjective factors. Therefore, due to the irregular operation and misoperation of the driver, urban road traffic congestion, reduced road traffic flow, and frequent major traffic accidents are caused. It is becoming more and more serious, which brings great inconvenience and harm to people's production and life. The driving and steering of unmanned vehicles is one of the important indicators to measure the performance of the vehicle, and the driving and steering devices of unmanned vehicles are The key to ensure the automatic steering performance of unmanned vehicles. The steering and driving devices of existing unmanned vehicles have complex structures, poor shock absorption effects, stuck phenomena, and poor steering control accuracy. Therefore, it is necessary to improve
