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)
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
Looking back at 2017, the upgrading of national regulations triggered a new round of reshuffle in the light passenger market. Many light passenger brands withdrew from the market with less than 9 seats. Faced with the continuous brewing changes in the consumer market, light passenger cars with front engine undoubtedly better conform to the development trend of the times. As a representative and leading enterprise of China's independent brand of passenger cars, Jinlong Light Bus has been forging ahead for 10 years, gathering the advantages of traditional light passenger cars, Carefully developing a new generation of multifunctional business light vehicles - Jinlong Kairui Haoke, ushering in a new era of front power for light vehicles with less than 9 seats On June 10th, Jinlong Kairui Haoke was grandly launched at the Xiamen Jinrong City Exhibition Hall. The new car is divided into a business version and a Haoyun version, with the business version divided into three models: standard, comfortable, and business. The price range is 82800 to 105800 yuan. The new car is committed to becoming a model of multifunctional business light passenger in the new era
