Embodiment Construction
[0008] A braking device for an unmanned vehicle, including a motor 10, the output shaft of the motor is fixedly connected to the input shaft of the reducer, and the output shaft 22 of the reducer passes through the electromagnetic brake 30 and the brake actuator 40 for maintaining the braking state of the vehicle The central shaft is fixedly connected, and the brake actuator 40 includes a wire winder 41 wound with a stay cord, one end of the stay cord is fixed on the wire winder 41, and the other end is connected with the support rod 44 of the brake pedal 43 , the motor 10 drives the wire winder 41 to make the stay cord pull the brake pedal 43 to brake. That is, the motor 10 drives the winding device 41 to rotate, so that the stay cord pulls the support rod 44, and the support rod 44 drives the brake pedal 43 to swing up and down, thereby controlling the braking force, such as figure 2 shown.
[0009] combine figure 2 , the stay rope adopts a steel wire rope 42, and one en...

The invention relates to a braking device of an unpiloted vehicle. The braking device comprises a motor, wherein the output shaft of the motor is fixed with the input shaft of a decelerator; the output shaft of the decelerator is fixedly connected with the central shaft of a brake actuating mechanism through an electromagnetic brake used for maintaining the braking state of the vehicle; the brake actuating mechanism comprises a winder on which a pull rope is wound; one end of the pull rope is fixed on the winder, while the other end is connected with the support rod of a braking pedal; and the motor drives the winder to ensure that the pull rope pulls the braking pedal to brake. By using the winder on which the pull rope is wound, the brake actuating mechanism is set as a guyed flexible connection mode; and when braking, the motor drives the central shaft of the winder to rotate, and the winder rotates clockwise or counterclockwise to elongate or shorten the pull rope in order to pull the braking pedal to swing up and down and to control the magnitude of a braking force. The braking device has the characteristics of small size, great output force, convenient installation and space conservation, and little influence on a driver after a driving state is switched to a manual driving state.
Description
technical field [0001] The invention relates to the technical field of vehicle braking, in particular to a braking device for an unmanned vehicle. Background technique [0002] At present, most of the unmanned driving technologies are in the stage of experimental development. Sensors are used to collect relevant data about the vehicle and the vehicle itself to control the mechanical structure, thereby replacing humans to complete the actions of steering, braking, accelerator, and shifting mechanisms. The existing automatic control devices of the braking system are all realized by hard connection, that is, driving the brake pedal. The size of the device in this design method is relatively large, occupying a large space in the cockpit, and it is inconvenient to switch to manual driving. . Contents of the invention [0003] The object of the present invention is to provide a braking device for an unmanned vehicle that saves layout space and is convenient for switching from a...
