Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and in particular relates to a mechanical transmission. Background technique [0002] At present, most of the transmissions in the field of automobile manufacturing are mechanical manual gear shifting. The gear shifting action is realized by manually controlling the joystick, and the clutch clutch action is realized through the foot pedal. During the gear shifting and clutching action process , the driver needs to skillfully control the joystick and clutch pedal. The main disadvantage is frequent manipulation and high labor intensity. Most of the automatic shift transmissions used in some high-end passenger cars are hydraulic transmission automatic shift transmissions (AT), which are mainly composed of hydraulic torque converters, gear transmission mechanisms, wet multi-disc clutches , composed of hydraulic valves and oil pumps, the hydraulic torque converter can automatically change its...

The main disadvantage is frequent manipulation and high labor intensity

Most of the automatic shift transmissions used in some high-end passenger cars are hydraulic transmission automatic shift transmissions (AT), which are mainly composed of hydraulic torque converters, gear transmission mechanisms, wet multi-disc clutches , composed of hydraulic valves and oil pumps, the hydraulic torque converter can automatically change its output torque and speed according to changes in the external load, and can absorb and eliminate the impact and vibration from the engine and external loads on the transmission system, so that the car can be maneuvered Simple and stable starting, but the large power loss of the hydraulic torque converter leads to large fuel consumption, low efficiency, poor maintainability and assembly of hydraulic transmission automatic shift transmission (AT)

An application number is 200410015154.5, and the name is an invention patent application for a clutch-type automatic transmission, which discloses a combined shift mechanism using a hydraulic coupling and a dual clutch, which can reduce the slippage of the friction plate and make the shift It is softer, but the power loss of the hydraulic coupling is still relatively large during the vehicle start and gear shifting process, and its energy consumption is still high
