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)

BAIC 212 introduce

BAIC 212 Series: Founded in 1958, Beijing Automotive Manufacturing Co., Ltd. is a representative of BAIC's independent brand. For more than 40 years, BAIC has focused on the development and production of light off-road vehicles and trucks, and has won the reputation of "off-road family". The BAIC BJ-212 was first developed in 1964, and in 1965, the BJ-212 series off-road vehicles were officially finalized. The BJ-212 at that time adopted a detachable soft top design, The BJ-212 Jeep is mainly used for commander riding, weapon transportation, and other purposes. It adopts front and rear steel plate spring non independent suspension, which has strong off-road capabilities. It finally achieved mass production in 1966. In terms of body size, its length, width, and height are 3910mm, 1760mm, and 1880mm respectively, with a wheelbase of 2310mm. In terms of power, the BJ-212 Jeep is equipped with a 2445cc inline four cylinder gasoline engine, which adopts four-wheel drive and front and rear drum brakes, Matched with the engine is a 3-speed manual transmission, which has a maximum power of 75 horsepower, a maximum torque of 172 Nm, a weight of 1395kg, a maximum speed of 120-130 km/h, and a fuel consumption of approximately 14L per 100 kilometers
