Abstract

The invention discloses a two-stage slope parking system and a vehicle. The two-stage slope parking system includes: a dual-stage slope parking manual valve, which has a first driving state, a parking state, and a temporary stop state; a parking brake subsystem, including The first relay valve and spring brake cylinder; the imminent stop function subsystem, including the second relay valve and the brake chamber; when the two-stage slope manual valve switches from the first driving state to the parking state, the The slope manual valve controls the first relay valve to exhaust the spring brake cylinder to realize the parking brake function; when the two-stage slope manual valve is switched from the parking state to the temporary stop state, the The first relay valve exhausts the spring brake cylinder, and the two-stage slope manual valve controls the second relay valve to charge the brake air chamber to realize the parking brake function and temporary stop function. The working states of the parking brake subsystem and the imminent stop function subsystem are controlled by the three states of the dual-stage slope parking manual valve. When the vehicle is parked on a slope, the two subsystems work simultaneously to improve the slope parking ability.

Description

technical field

[0001] The invention relates to the technical field of automobiles, in particular to a two-stage parking slope system and a vehicle. Background technique

[0002] At present, commercial vehicles on the market generally have heavy load-bearing working conditions. Under such working conditions, the parking brake system of the original car cannot provide enough parking force to meet the actual needs of users, especially in areas with large slopes such as mountainous areas. The parking capacity requirements are higher under heavy load conditions. In the prior art, the reliability of the temporary parking of the vehicle is relatively low, and the prior art still needs to be improved and developed. Contents of the invention

[0003] The object of the present invention is to provide a two-stage parking slope system and a vehicle, so as to solve the problem of insufficient parking capacity in the prior art when the vehicle is parked on a slope or other working con...
