Description
Technical Field
The invention relates to the field of automobile brake devices, in particular to a hydraulic brake with a scraper blade recoverer of a scraper blade type hydraulic pump.
Background
The brake is divided into a foot brake and an exhaust brake, the foot brake is realized by pressing a wheel drum by a brake pad and preventing the wheel drum from rotating by friction, the exhaust brake is realized by closing an exhaust pipe, the pressure in a cylinder is increased, and a piston is prevented from moving upwards to rotate a crankshaft.
The exhaust brake is to close the exhaust pipe, before the lower dead center of the piston ascends when the engine exhausts, the exhaust valve is opened, no air pressure exists in the cylinder, so that the air pressure in the exhaust pipe returns to the cylinder through the exhaust valve, the push-stop piston ascends, before the piston compressed air ascends to the upper dead center, the intake valve is opened, and the exhaust valve is opened, so that high-pressure air in the cylinder and in the exhaust pipe is released through the intake valve and the exhaust valve, the high-pressure air does not push the push-stop piston to move upwards, the brake effect of the exhaust brake is poor, and the brake cannot be stopped. When the vehicle goes down the long slope, the speed of a motor vehicle is too fast just will brake, so only can let the brake block with the friction of wheel drum, let the speed of a motor vehicle slow down, just will brake as soon as the speed of a motor vehicle is opening the brake, the brake block will only generate heat with the friction of wheel drum high strength and scald, because the wheel drum is not good with brake block heat dissipation, heat can accumulate, brake several times back, the wheel drum will be high temperature to not having frictional force with the brake block, scald and brake also malfunctioning at this time, the heat dissipation of wheel drum all is that driver oneself installs the water tank additional on the car now, it is radiating on the wheel drum to spray water, so also dangerous, because the wheel drum is iron does, spray water and dispel the heat on the wheel drum when high temperature, the metal can contract and can warp and split, it is poor with brake block frictional force to have deformed the wheel drum, braking force is not good. The wheel drum is cracked and has no braking force, the brake is also out of order, and people know that the traffic accidents of car damage and people death caused by the brake loss of the downhill foot are many, ninety percent of the traffic accidents are that the wheel drum is scalded and out of order, the exhaust brake is air-pushed and blocked, the air can be compressed and does not have high-pressure air, and therefore the resistance is poor.
