The invention provides a parking braking system. The parking braking system includes a parking brake, a parking braking control handle, and a transmission mechanism arranged between the parking brakeand the parking braking control handle; the transmission mechanism includes a first drawbench, a first rack, a small gear, a large gear, a second rack and a second drawbench, wherein the two ends of the first drawbench are connected with the parking braking control handle and the first rack respectively; the installment shaft of the large gear and the installment shaft of the small gear are arranged parallel to each other; the diameter of the addendum circle of the large gear is larger than the diameter of the addendum circle of the small gear; the small gear is arranged between the first rackand the large gear, one side of the small gear is meshed with the first rack, and the other side of the small gear is meshed with the large gear; the two ends of the second drawbench are connected with the parking brake and the second rack respectively, and the second rack is used for being meshed with the large gear; the transmission ratio of the large gear to the small gear is larger than 1. The parking braking system can greatly improve parking braking force. The invention further provides a car.
Description
technical field [0001] The invention relates to the technical field of automobile brake systems, in particular to a parking brake system and an automobile. Background technique [0002] The parking brake system can realize the parking and quick release of the vehicle, and can also realize dynamic parking. Existing parking brake system usually comprises parking brake control handle, parking brake and the parking brake operation wire drawing that is used to connect parking brake control handle and parking brake, and it is in use, and driver passes Manipulate the parking brake control handle, so that the pulling force is transmitted to the parking brake through the parking brake control wire, so that the parking brake works to realize the parking of the vehicle. [0003] However, the adjustment of the parking brake force in the existing parking brake system can only be realized by adjusting the lever ratio of the parking brake handle, but the lever ratio is generally 4 to 4.5,...
