Background

Although the parking brake used for parking the motor vehicle at present can meet the parking requirement, the parking brake can cause instant failure of braking under the condition of mechanical part breakage or electronic function failure because of mechanical brake pull-wire braking or electronic brake type braking, and at the moment, if the vehicle is parked on a ramp, the vehicle slips forwards and backwards under inertia, so that the loss of personnel and property is caused, and particularly, serious traffic accidents are often caused when the vehicle slips. Therefore, most drivers who park on a half slope can insert the cushion blocks at the bottom sides of the wheels to prevent the vehicle from rolling. However, the cushion needs the driver to bend down and fill in the wheel bottom side when using, when not being equipped with special wood block piece, still need look for fragment of brick or stone everywhere as interim cushion, and the back that finishes using, the process of taking out the cushion from the wheel bottom is also inconvenient, and a bit of driver can not take out interim cushion such as fragment of brick or stone even, directly leaves over it on the road surface, and this can cause the potential safety hazard to other past vehicles. Under special conditions, if the parking brake system fails to brake when the motor vehicle is parked on a half slope, a driver is required to step on the brake all the time, and people on other sides can get rid of the trouble only by plugging the pad blocks at the bottom sides of the wheels. Therefore, the market needs a vehicle-mounted wheel device which is arranged at the bottom of the vehicle, so that a driver can complete the operation of wheel cushion and cushion block retraction in a cab when the vehicle is parked.
