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)

Mercedes Benz B-Class introduce

This Mercedes Benz B-Class is currently the cheapest entry-level car with the Mercedes Benz logo, and it is also the cheapest model in China that is equipped with an active parking assist system. In addition, there is a unique panoramic sunroof structure. Unlike the Mercedes Benz C200, the Mercedes Benz B200 uses a specially designed 2.0L inline four cylinder engine installed in the car with a slight tilt, which not only complements the special chassis structure of the B200, but also, And it can keep the cockpit as far away from the frontal collision area as possible. It is equipped with an AUTO TRONIC continuously variable transmission, also known as a CVT transmission. After being recalibrated by Mercedes Benz, it can output a maximum power of 100 kW and a torque of 185 Nm. In actual testing, the initial response of the electronic throttle is still a bit sluggish, but it is most frequently used in the area of 2500 to 3500 rpm, Having sufficient low torque performance for daily use. After shifting the gear to manual mode, the CVT gearbox with a 7-speed setting immediately enters sport mode, and the switching method is also more convenient. Although it enters sport mode, it is obvious that this car is not born for sport, so the expected value should not be too high, and the sport mode cannot have the expected push back feeling As a compact sports wagon, the Mercedes Benz B-Class has a stylish and dynamic appearance. The large three pointed star emblem on the front face is embedded in the center of the trapezoidal grille, revealing its identity. The lines on the engine compartment cover contract inward, making the headlights on both sides more sharp. The combination of the bumper and front fog lights gives the Mercedes Benz B-Class a powerful appearance
