Speed transforming transmission of parking braking system of automobile

Abstract

The invention discloses a variable-speed gear for a parking brake system of a motor vehicle. The variable-speed gear consists of a spring for storing energy required for releasing brake, two or more than two locking mechanisms, and two or more than two groups of operating guys, which are combined with each other. The variable-speed gear has the advantages that when the operating acting force for implementing brake on a vehicle is not large, the variable-speed gear amplifies the working stroke for implementing brake on the vehicle by an operating rod for a plurality of times for transmission, so as to increase the working stroke for implementing brake on a braking mechanism of the vehicle by the operating rod; and when the operating acting force for implementing brake on the vehicle is large, the variable-speed gear amplifies the acting force for implementing brake on the vehicle exerted by the operating rod for a plurality of times for transmission, so as to increase the limited operating acting force and make the acting force for implementing brake on the braking mechanism of the vehicle large. When the variable-speed gear is matched with a vehicle in any vehicle type for use, people only need to replace the operating guys which are connected with the variable-speed gear, so that the variable-speed gear is convenient to promote.

Description

technical field [0001] The invention relates to an automobile parking brake, in particular to a speed change transmission device of the automobile parking brake system. Background technique [0002] Chinese Patent Announcement No. 200610173368.3 discloses "a kind of braking method of vehicle" and the device used in the disclosed method needs to change the parking brake joystick and the joystick fixing support of the vehicle that has been shipped from the factory or have been finalized before it can be used. It is suitable for the installation and use of vehicles that have already been finalized, and it cannot be used for refitting vehicles that have already left the factory. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the technology of the announcement number 200610173368.3, and provide a variable speed transmission device for the parking brake system of an automobile. This device is configured on the present ...
