What is the principle of electric vehicle oil brake?

Principle of electric vehicle oil brake: When braking, the oil in the small oil pump of electric vehicle generates pressure to push the brake pad to achieve the braking purpose and control the brake disc.

The braking principle of electric cars and cars is almost the same, that is, when you brake, the metal diaphragm is closely combined with the metal ring of the tire shaft, and when you rub the car, you slow down until you stop. The brake handle of the electric vehicle is pressed on the piston (in the oil storage box), and the piston compresses the oil to produce the oil pressure brake.

When the brake handle is released, the piston will reset due to the existence of oil pressure, so that the brake handle is reset, and then the switch is pressed by the brake handle (to protect the brake from power failure). This system has two important parts, oil and sealing ring.

If the sealing ring is worn and the seal fails, the oil brake will not work. Unless the sealing ring is replaced or completely replaced, it will not be so easy to break down in normal use.

Maintenance of electric vehicle oil brake:

1. Change the brake fluid frequently.

Many users often buy new cars until they are damaged, which is not right. Brake fluid, commonly known as brake oil, is used to transfer the driver's strength to the brakes.

If the brake oil is dirty and the viscosity increases, it will directly affect the braking force of the vehicle, which is reflected in the driver's feeling that the brake is "too soft". Therefore, brake oil should be changed every six months.

2. Check the worn parts.

In addition to brake fluid, the oil brake system needs to pay attention to the brake pads of worn parts regularly. When the vehicle is running, the sand and gravel on the road surface will often get involved in the space surrounded by the brake hub and the brake disc, and these involved sundries will hit the brake pads at high speed.

In the process of braking, it will cause uneven running-in of brake pads. Therefore, when braking, you will feel that the strength is not enough, the response is slow, and sometimes it will shake. Therefore, you should regularly check the wear degree and surface uniformity of brake pads.
