Embodiment Construction

[0017] The structure and function of the present invention will be described below in conjunction with the drawings

[0018] see figure 1 , the power of the engine is input from the input shaft to the transmission, and the gears 4, 7, 9, 12 are vacantly sleeved on the input shaft 1, the gear 4 is meshed with the inner planetary gear 19, the gear 7 is meshed with the outer planetary gear 17, and the gear 9 and the gear 12 mesh with the double gear 14, and the double gear 14 is connected with the outer ring gear 23 of the double-layer planetary gear train 16 by splines.

[0019] The wet multi-disc clutches 5, 6, 10, 11 are fixedly connected to the input shaft 1, the wet multi-disc clutch 5 controls the combination and separation of the input shaft 1 and the gear 4, and the wet multi-disc clutch 6 controls the combination and separation of the input shaft 1 and the gear 7 Separation, the wet multi-disc clutch 10 controls the combination and separation of the input shaft 1 and th...

Abstract

The invention relates to a double-layer planet gear train speed changer. The speed changer utilizes the motion combination of a hydraulic or electronic-controlled wet type multi-gear clutch and a bandbrake to synthesize the motive power and rotation speed of an input shaft through a double-layer planet gear train and then output the synthesized motive power and rotation speed from an output shaftso as to make the speed changer have 10 forward gears and one reverse gear. The speed changer is easy to automatically control, can achieve the effect of stepless speed change, and improves economy and dynamic properties of vehicles.

Description

technical field [0001] The invention relates to a speed changer, which is suitable for various automobiles, realizes more gears through fewer parts, achieves the effect of quasi-stepless speed change, and improves the economy and power of the vehicle. Background technique [0002] At present, the transmissions used on ordinary manual transmission cars and light and medium trucks generally have only 3 to 6 forward gears and one reverse gear. Existing mechanical continuously variable transmissions have relatively high manufacturing requirements and high costs, and can only be used for light vehicles. For ordinary manual transmission cars and light and medium-sized trucks, appropriately increasing the gears and realizing quasi-continuously variable transmission through simple operations will improve the economy and power of the vehicles. Contents of the invention [0003] The object of the present invention is to provide a double-layer planetary gear train transmission, whic...
