Abstract

The invention discloses a piston braking system and a braking method thereof. The piston braking system comprises transmission rotating shafts located between a starting component and a working component, pistons, and a pressure adjusting mechanism, wherein each piston is connected with the corresponding transmission rotating shaft; when each transmission rotating shaft rotates, the correspondingpiston is driven to be in straight reciprocating motion in a cylinder jacket; a pressure adjusting cavity is formed between each piston and the cylinder jacket; the pressure adjusting mechanism is used for adjusting the pressure in the pressure adjusting cavities, and comprises an inlet pipe and a discharging pipe, wherein the inlet pipe and the discharging pipe separately communicate with the pressure adjusting cavities; one-way valves are respectively arranged in the inlet pipe and the discharging pipe; and an adjusting valve is also arranged in the discharging pipe. Every time the transmission rotating shafts rotate for a circle, the pistons are driven to make a complete reciprocating motion, and in the process, the volume of each of the pressure adjusting cavities is enlarged and reduced. Through the adoption of the piston braking system disclosed by the invention, the problem that a conventional braking manner adopts a manner that kinetic energy is transformed into internal energythrough friction, so that the condition that wear of brake cannot be thoroughly and radically solved to cause invalid slipping is solved, and the purposes of breaking the shackles in the prior art and stopping braking failure caused by damage of friction are realized.

Description

technical field [0001] The invention relates to the field of braking, in particular to a piston braking system and a braking method thereof. Background technique [0002] Vehicle braking system, also known as braking, refers to the action of stopping or reducing the speed of running locomotives, vehicles and other means of transportation or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, install a corresponding brake shoe, belt or disc on the machine base, and make it generate braking torque under the action of external force. The brake device is also a mechanical brake device that can slow down the speed of the vehicle, also known as a reducer. To put it simply: the brake pedal of the car is under the steering wheel. If you step on the brake pedal, the brake lever will be linked and pressed, and the brake pads transmitted to the brake drum will block the brake wheel, so that the car will slow down or stop runnin...
