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

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
