operating cylinder introduce

The function of the brake cylinder assembly in a car: 1. When the brake is pressed, the master cylinder generates thrust, which pushes hydraulic oil pressure to the cylinder. The piston inside the cylinder begins to move under hydraulic pressure, pushing the brake pads forward; 2. The oil brake is composed of a brake master cylinder and a brake oil storage tank. They are connected to the brake pedal at one end and the brake oil pipe at the other end. The brake master cylinder stores brake oil and has oil outlet and inlet ports. When the brake is pressed, the oil outlet opens and the oil inlet closes; 3. Under the pressure of the piston in the pump body, the brake oil pipe is squeezed out of the oil pipe and flows to each brake cylinder to perform the braking function. When the brake pedal is released, the oil outlet in the brake master cylinder will close and the oil inlet will open, allowing brake oil to flow back from each brake cylinder to the brake master cylinder and return to its original state. Automotive brakes are divided into air brakes and hydraulic brakes. Heavy trucks use air brakes, while small cars generally use oil brakes. When braking, when you press the brake pedal, The brake master cylinder sends brake oil through pipelines to each brake cylinder. The brake cylinder has a connecting rod that controls the brake shoes or brake pads. When braking, the brake oil in the brake oil pipe pushes the connecting rod on the brake cylinder, causing the brake shoes to tighten the flange on the wheel and stop the wheel. The brake cylinder is an indispensable part of the braking system, and its main function is to push the brake pads, which rub against the brake drum, Reduce vehicle speed and come to a standstill. Working principle: After stepping on the brake, the master cylinder generates thrust to reverse the hydraulic oil pressure in the slave cylinder. The piston inside the slave cylinder begins to move under hydraulic pressure, pushing the brake pads. When the brake is applied, the oil outlet opens and the oil inlet closes. Under the pressure of the pump piston, the brake oil pipe is squeezed out of the oil pipe and flows to each brake slave cylinder for braking function. When the brake pedal is released, the oil outlet in the brake master cylinder will close and the oil inlet will open, Return brake fluid from each brake cylinder to the brake master cylinder and return to its original state)

NIO ET7 introduce

The NIO ET7 is a pure electric sedan launched by NIO, released in Chengdu on January 9, 2021. The NIO ET7 is equipped with an 8-megapixel high-definition camera, an AQUILA NIO ultra sensing system with ultra long range and high-precision LiDAR, and an ADAM NIO supercomputing platform, achieving full coverage of high-speed, urban, parking, and changing fields, bringing a safe and relaxed point-to-point autonomous driving experience. Moreover, the NIO ET7 inherits high-performance genes, with a drag coefficient as low as 0.23Cd, The acceleration from 100 kilometers per hour is only 3.9 seconds, and the braking distance from 100-0 km/h is only 33.5 meters. The new car has a range of over 1000 kilometers, and is equipped with intelligent air suspension and dynamic damping control as standard across the entire range. Equipped with 4D intelligent body control, it creates a comfortable journey
