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)

Audi A4L introduce

The Audi A4L is an entry-level luxury B-class sedan produced by FAW Audi. The characteristics of this car are its atmospheric and stable body, meticulous workmanship, solid materials, rich configuration, spacious space, and good handling A4L was officially released on November 16, 2008, and the front face design of the new Audi A4L continues to use the family's expensive sports car design style. The price range of Audi A4L is 272800-578100. The domestic version of the new generation Audi A4 was officially named: Audi A4L. Audi A4L is a new car that Audi only launched in the Chinese Mainland market. The relationship between the new car and A6 and A6L is similar, and it is also after foreign models are made in mainland China, A model derived from changes in configuration and market demand. After higher level mid to high end luxury cars have chosen to be lengthened in China and received good market feedback, this idea is now extending to its lower level mid size car market. Compared with the European version of the Audi A4, the domestic version of the Audi A4L has lengthened the body length by 60mm, reaching 4763mm, and the wheelbase has been lengthened by 61mm, reaching 2869mm, Satisfying the higher requirements of Chinese users for rear passenger space
