Abstract

The invention discloses a temporary parking slope-parking system and a vehicle, and relates to the technical field of vehicle parking braking. The temporary parking slope-parking system comprises a mechanical parking device, a pneumoelectric double-control memory valve and a pneumatic parking device; the mechanical parking device comprises a manual valve, a first parking relay valve and a spring brake cylinder, and the manual valve and the first parking relay valve are both connected with an air source; the pneumoelectric double-control memory valve is provided with a control valve air inlet, a control valve air outlet, a control valve air outlet and an electrical interface, the electrical interface can be communicated with a power supply to drive a valve block to move to a first preset position and keep the valve block, and a control valve control port can be communicated with a first air inlet through a first air outlet to drive the valve block to move to a second preset position and keep the valve block; and the pneumatic parking device comprises a second parking relay valve and a brake air chamber, the second parking relay valve and the pneumoelectric double-control memory valve are both connected with the air source, and the second parking relay valve is connected with the brake air chamber. The parking stability, reliability and safety are improved.

Description

technical field [0001] The invention relates to the technical field of vehicle parking brakes, in particular to a parking slope parking system and a vehicle. Background technique [0002] At present, the ramp system of commercial vehicles starts later than that of passenger cars, especially for medium and heavy trucks. Generally, the method of manual valve + parking relay valve is used for parking. The parking principle is: when parking, pull the manual valve to make it in the parking position, and the gas at the control port of the parking relay valve is exhausted through the parking manual valve. so that the exhaust port of the parking relay valve is connected with the air outlet, and the gas in the spring brake cylinder enters the parking relay valve through the pipeline and is quickly discharged through the exhaust port to brake and park the vehicle; When parking, pull the manual valve to connect the air inlet and outlet, the gas in the air storage tank will reach the c...
