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

Wuling Rongguang Mini Card introduce

Wuling Rongguang small truck is a model specially produced by Wuling for the increasingly competitive small truck market. Wuling's vans are undoubtedly the king of their kind, which is well-known. However, Wuling's small trucks are far from as glamorous as Chang'an, with a low chassis and high accessory prices, The unsatisfactory cost-effectiveness has always led to low sales of Wuling series trucks. However, the Wuling Rongguang small truck launched in late 2011 broke this situation. Although there was still no improvement in the issue of low chassis, the 1.2-liter displacement and 2.75-meter cargo box matched it surpassed the Changan New Leopard, which has always been known for its large cargo box! The relatively cheap price allowed this model to achieve impressive sales results in just a few months after its launch. Based on our sales data, if we maintain this market situation, it may only take 5 years or even less. In terms of market share of small trucks, Changan will have to hand over the first place to Wuling
