Problems solved by technology

[0004] 1. There are many cable connection interfaces, which increases the manufacturing cost and assembly difficulty;
[0005] 2. A balancer must be redesigned inside the mechanism
[0007] However, there are still some problems to be overcome in the above-mentioned existing single-cable parking brake design, including the shortened service life of the cable due to the frequent stress of the cable under the situation of large bending
In addition, due to the greater degree of bending of the cables, the mechanical efficiency is reduced

Abstract

The invention relates to a single-cable type driving device for a parking system, which comprises an outer tube moving assembly and a driving assembly, wherein the outer tube moving assembly comprises at least one brake cable outer tube which is coated outside a brake cable, the driving assembly comprises a driving element for driving the outer tube moving assembly to perform axial movement; and with the movement of the outer tube moving assembly, the brake cable outer tube generates acting force to the brake cable to further control the braking force of a brake. The brake cable is not neededto be bent to a large extent, thus the service life and the mechanical efficiency of the driving device can be improved.

Description

technical field [0001] The invention relates to a braking system, especially to a driving device of a parking system, which can improve the durability and mechanical efficiency of the driving device. Background technique [0002] The traditional mechanical parking brake system is also known as the hand brake. It uses the hand brake handle installed in the car. When the user pulls the hand brake handle upward, it will drive the mechanical parking brake to lock the brake, thereby achieving The purpose of the parking brake. However, because the traditional mechanical parking brake system must be equipped with a handbrake handle inside the car, the interior space of the car is reduced, and it does not conform to the electronic trend of the current automobile industry. [0003] The existing electronic parking system uses an electronic controller to control the driving device of the parking system, so the user can conveniently operate the parking system by means of buttons, and t...
