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)
The super practical storage space of Beijing Automotive Beijing-U7 (formerly known as Beijing Automotive Zhidao U7) has reduced a lot of trouble for travel. The most pleasing aspect of the front storage space is its central armrest box. The two-piece design supports left and right split opening. This design is generally only found in high-end models of Mercedes Benz and BMW, and it is not easy to make the armrest box so innovative at this price point, The space design of this central armrest box is also excellent, with a large depth and strong practicality. In addition, there are two central cup holders in front of the central armrest box, which are just right for storing mineral water. The largest storage compartment in the central control area is located in the area in front of the gear lever, and there are also two USB ports and a 12V power supply. In addition, there is a small storage compartment on the left side of the driver's side, It can be used to store change, bills, and other miscellaneous items. The storage space inside the front glove box and door panel is also large, and the interior of the glove box is treated with flocking, so it is not afraid of scratching valuable items
