Abstract

The invention discloses a twist emergency braking and parking brake. The twist emergency braking and parking brake comprises a support frame, friction plates and a brake drum. The two ends of each friction plate are provided with protrusions. An annular push iron is mounted in the positions, close to the protrusions of the friction plates, of the support frame. A cam shaft is embedded on the sideportion of the push iron. The position of the cam shaft making contact with the side portion of the push iron is provided with a top end cam and a body cam. The other end of the cam shaft penetrates through a rocker arm to be connected with a rotary power source. The twist emergency braking and parking brake simultaneously and synchronously drives the push iron through rotation of the top end camand the body cam on the cam shaft, so that the push iron pushes the protrusions of all the friction plates upwards to form friction braking with the brake drum through the rigidity of the push iron. Accordingly, the twist emergency braking and parking brake realizes emergency braking and parking braking, the installation space can be reduced, and the working efficiency of safety braking is improved.

Description

technical field [0001] The invention relates to a vehicle braking system, in particular to a brake. Background technique [0002] At present, vehicle safety brakes mainly solve the functions of driving emergency braking, fault monitoring, automatic cooling, cleaning and dust removal, etc. To realize parking braking, another set of parking braking devices needs to be installed in its corresponding position, occupying Limited space in the vehicle. There is a lack of a device that combines the functions of driving emergency braking and parking braking, which affects the working efficiency of safety braking. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a torsional emergency braking and parking brake which can integrate driving emergency braking and parking braking. [0004] The purpose of the present invention is achieved through the following technical solutions: the torsional emergency b...
