Description

Secondary parking brake device for vehicles {a supply devide to parking for veichle}

The present invention relates to an auxiliary brake device of a vehicle.

In general, a vehicle braking device is an important device used to slow down or stop a vehicle while driving and to maintain a parking state. Generally, a frictional force is used to convert a vehicle's kinetic energy into thermal energy and release it into the atmosphere. Friction brakes are used to make them brake.

In addition, the brake system is the main brake (Foot Breake) mainly used for driving and the parking brake (Parking Breake) used for parking the car, and the main brake is called the foot brake because it is operated by the driver's foot. It is also called a hand brake because it is operated by hand.

The parking brake is a device that keeps the vehicle in a stationary state, also called a hand brake or side brake. When the handle lever is pulled, the shoe lever in the rear brake device is moved by a cable, so the lining is in close contact with the drum. It is supposed to maintain braking state.

Such parking brakes are most commonly used in cars.

At this time, the lining 114 which is in close contact with the drum 113 may not be crimped, and thus parking may occur. There is a very unreasonable problem of losing the braking force, which leads to a dangerous situation.

Accordingly, the present invention has been invented to solve the above problems, to ensure the safety of the stable parking by exhibiting the vehicle's reliable parking braking ability under any road conditions, as well as support when parking on sloped ground Or it aims to improve the convenience of the driver so that auxiliary means such as boulder is not necessary.

The present invention for achieving the above object is connected to the axle for transmitting the driving force is pushed to the outside of the main shaft and the wheel provided to slide by the elastic force of the elastic member inserted in the spindle inner diameter for rotating the wheel to the road surface by its own weight It is characterized in that the control shaft is coupled to the screw thread to be able to adjust the length in the auxiliary shaft connected to be bent and the braking plate is adjustable to the fine length coupled to form a screw thread inside the control shaft.
