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

BMW 320i introduce

The dimensions of the BMW 320I model are 4531mm * 1817mm * 1421mm, with a reference price of 31000-388800 yuan. BMW started its business by producing aviation engines, so the blue color on the logo represents the sky, and the white color represents the symmetrical graphics of the propeller/blue and white markings; The predecessor of the state emblem/BMW, which is also the location of the company in Bavaria, was an aircraft factory. It was founded on March 7, 1916 and was initially famous for manufacturing streamlined biplane reconnaissance aircraft. At that time, the company's name was BFW (BayerischeFlugZeugWork), meaning "Bavarian Aircraft Manufacturing Plant", and the founder of the company was Gustan Otto, His father was a renowned inventor of four stroke internal combustion engines, and his high achievements in aviation made him ambitious in manufacturing cars. He wrote a glorious chapter in the history of automobiles, which is the founding of the BMW factory in Germany, which is loved by millions of car enthusiasts today
