Transmission valve body introduce

Transmission valve body: Introduction to the transmission valve body: 1. The transmission valve body can be used for shifting between high and low gears. When the vehicle speed reaches a certain gear, hydraulic oil pushes the valve body to automatically shift the gear to that gear. The automatic transmission can automatically change the transmission ratio according to the engine load and speed, so that the car can achieve good power and fuel economy, and reduce engine emissions pollution. 2. The automatic transmission is easy to operate, When vehicles are congested, it can greatly improve the safety and reliability of vehicle operation. Electronic controlled automatic transmissions are usually composed of five parts: hydraulic torque converter, planetary gear transmission system, shift actuator, hydraulic control system, and electronic control system)

Symptoms of Damaged Transmission Valve Body

The function of the gearbox valve body is to drive the gearbox to shift high and low. The gearbox valve body controls various shifting mechanisms by converting the oil circuits inside the valve body. Of course, there may be damage to components on the vehicle, such as the gearbox valve body. The reasons for damage may include the following: 1. Insufficient internal pressure caused by structural damage or insufficient sealing inside the valve body, resulting in difficulty in separating or combining shifting actions; 2. The electromagnetic valve or mechanical part inside the valve body is damaged, causing the original function to not function properly; 3. If the oil in the valve body is used for too long and there are too many impurities in the oil, it will cause the valve body to operate slowly. If the time is too long, it will exacerbate the wear of the valve body. Symptoms of a damaged transmission valve body: 1. Impact sensation during upshifting and downshifting, and obvious jerking during shifting; 2. There is a strong jerking sensation when shifting gears, and the shifting motion is not smooth, etc; 3. The gearbox makes abnormal noises while driving; 4. The instrument panel displays a transmission fault light

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
