Abstract

The invention discloses a multi-mode output intermediate-shaft-free stepless speed change transmission system which is characterized in that an engine output shaft is connected with a power output shaft through a joint sleeve, and the power output shaft is simultaneously connected with a planet carrier and a driven disc of a clutch C2; a generator rotor shaft is connected with a sun wheel shaft through a joint sleeve, and the sun wheel shaft is connected with a sun wheel; a rotor shaft of the motor is connected with an input shaft of a gearbox through a joint sleeve; the input shaft of the gearbox is simultaneously connected with a gear Z1, a driving disc of an overrun clutch and a driven disc of a clutch C1; a driven disc of the overrun clutch is connected with a gear Z3; the C1 / C2 driving disc is connected with a planetary gear ring; a central transmission driving shaft is simultaneously connected with a driven disc of a clutch C3 and a gear Z4; a driving disc of the clutch C3 is connected with the gear Z2; and the gear Z1 is meshed with the gear Z2, and the gear Z3 is meshed with the gear Z4. Therefore, the function that the vehicle runs in the three CVT modes can be achieved, and the purposes of saving oil and reducing emission of the whole vehicle can be achieved.

Description

technical field

[0001] The invention relates to a new CVT (Continuously Variable Transmission) continuously variable transmission system for high-horsepower tractors and off-road vehicles, in particular to a multi-mode output continuously variable transmission system without an intermediate shaft. Background technique

[0002] The existing non-road transmission system is divided into manual shifting system according to shifting mode; stepless power uninterrupted automatic shifting system; stepless continuous CVT shifting system.

[0003] 1. Manual shift system: a shift system composed of a manual shift lever, a shift shaft and a shift fork; when shifting, the system needs to separate the main clutch, cut off the power of the gearbox input shaft, and manually select and shift gears During the process, it is necessary to stop and change gears during operation.

[0004] 2. Power uninterrupted automatic shifting system: refers to the shifting process of the vehicle under the co...
