Hydraulic brake with scraper recoverer for scraper type hydraulic pump

Abstract

The invention provides a hydraulic brake with a scraper recoverer for a scraper type hydraulic pump, which relates to the field of automobile brake devices and comprises the scraper recoverer, the scraper recoverer comprises a shell, a rotating shaft is arranged in the shell, a rotor is arranged on the outer side of the rotating shaft, and a spring piece is arranged on the outer side of the rotor.Scraping blade recoverer pistons are arranged at the positions, located on the left side and the right side, in the shell, a scraping blade is arranged between the left scraping blade recoverer piston and the right scraping blade recoverer piston, an oil inlet and an oil outlet are formed in the upper side and the lower side of the right side of the shell correspondingly, and air paths are arranged on the left side and the right side of the shell. Rotors of scraping blades are arranged. High-pressure hydraulic oil is used for pushing and stopping the rotors of the scraping blades to rotate tobrake resistance, the hydraulic oil works in a circulating and reciprocating mode and can flow to a cooler through a pipeline to be cooled, the whole device is clear in thought, a running vehicle canbe rapidly braked and stopped, driving safety is guaranteed, traffic accidents are avoided, and the invention is safe and effective. The invention is practical.

Description

technical field [0001] The invention relates to the field of automobile brake devices, in particular to a hydraulic brake with a scraper type hydraulic pump and a scraper recoverer. Background technique [0002] There are two types of brakes: foot brakes and exhaust brakes. Foot brakes are used to squeeze the drum by the brake pads, and the friction prevents the drum from rotating to achieve braking. The exhaust brake is to close the exhaust pipe, increase the pressure in the cylinder, and prevent the piston from moving upward. The crankshaft rotates to achieve braking. [0003] The exhaust brake is to close the exhaust pipe. When the engine exhausts, before the bottom dead center of the piston moves upward, the exhaust valve opens, and there is no air pressure in the cylinder. In this way, the air pressure in the exhaust pipe returns to the cylinder through the exhaust valve, pushing and blocking the upward movement of the piston. The piston compresses the air up to the to...

[0003] The exhaust brake is to close the exhaust pipe. When the engine exhausts, before the bottom dead center of the piston moves upward, the exhaust valve opens, and there is no air pressure in the cylinder. In this way, the air pressure in the exhaust pipe returns to the cylinder through the exhaust valve, pushing and blocking the upward movement of the piston. The piston compresses the air up to the top dead center, the intake valve is opened and the exhaust valve is also open, so that the high-pressure gas in the cylinder and exhaust pipe will be released through the intake and exhaust valves, and there will be no high-pressure gas to push the piston Upward movement, so the braking effect of the exhaust brake is not good, and the car cannot be stopped

When the vehicle goes down a long slope, the vehicle will brake if the speed is too fast, so the brake pads and the wheel drums can only be rubbed against the brakes to slow down the speed of the vehicle. When the brakes are released, the brakes will be braked as soon as the vehicle speed is too high. The brake pads and the wheel drums are high-strength Friction will cause heat, because the heat dissipation of the wheel drum and the brake pads is not good, the heat will accumulate, after several times of braking, the wheel drum and the brake pads will be so hot that there is no friction, and the brakes will also fail when they are hot. Now the heat dissipation of wheel drums is done by the driver himself installing a water tank on the car and spraying water on the wheel drums to dissipate heat. This is also dangerous because the wheel drums are made of iron. It will shrink, deform and crack, and the friction between the deformed drum and the brake pads is poor, and the braking force is not good.

The wheel drum is cracked and there is no braking force, and the brakes are also out of order. We all know that there are many traffic accidents caused by car crashes and fatalities due to brake failure on downhill slopes. The air brake is pushed by the air, the air is compressible, and there is no high-pressure air, so the resistance is poor
