Problems solved by technology
[0013] (1) Tractors with manual shifting drive trains need to stop and shift frequently to meet the traction and speed requirements of farm implements. The work intensity is high, the work efficiency is low, and the quality is unstable.
[0014] (2) The engine speed changes with the speed of the vehicle and cannot automatically shift gears, resulting in the engine not working in a stable and economical speed range, high fuel consumption, poor emissions, and large vibration wear
[0018] (1) The engine cannot run stably in a small speed range, although the non-stop shifting is realized, the engine fuel consumption, emissions, vibration wear and other indicators are poor
[0019] (2) The transmission system structure requires a large number of clutches and proportional valves. With the increase of clutch wear, the shift control law will change with the change of clutch wear, operating environment temperature, and oil cleanliness; Poor stability
[0020] (3) The traditional power shift gearbox, to achieve super crawling gear (ultra-low speed), needs to add a complicated reduction gear train; it is difficult to achieve a crawling speed of 0.2-0.4Km / h
[0021] (4) The key technology of the system is mastered by foreign companies and mainly depends on imports. The price of the transmission system is high and the maintenance cost is high
[0025] (1) The mechanical transmission system consisting of 4-6 gears is a transmission mechanism composed of multi-row planetary mechanisms and multiple wet clutches or brakes. The structure is complex and the cost is high
[0026] (2) The hydraulic power distribution system composed of hydraulic precision coupling parts has very high requirements on the cleanliness of use and maintenance, and the cost of use and maintenance is high
[0027] (3) Because the technology of these systems is basically mastered by foreign companies, the products mainly rely on imports, and the cost is very high

The invention discloses a double-clutch differential confluence stepless speed change transmission system. According to the system, a motor output shaft is connected with a Z1 driving gear; a generator shaft penetrates through the motor output shaft and then is connected with a gear ring output shaft and a planet row gear ring; an engine output shaft penetrates through the generator shaft and then is connected with a planet carrier shaft; a sun gear shaft is connected with a sun gear, a Z3 driving gear and a C2 clutch driving disc at the same time, and the engine output shaft penetrates through the sun gear shaft and then is connected with a C2 clutch driven disc; a power output shaft is connected with the C2 clutch driven disc; a power converging shaft is connected with a Z2 driven gear; an input shaft of a gearbox is connected with the power converging shaft and a C1 clutch driven disc at the same time; a C1 clutch driving disc is connected with a Z4 driven gear, and the Z1 driving gear is meshed with the Z2 driven gear, and the Z3 driving gear is meshed with a Z4 driven gear. Therefore, the planet row is divided into two power lines, and multiple functions of division and confluence of electromechanical power and in a stepless speed change mode are achieved.
Description
technical field [0001] The invention relates to a continuously variable transmission system of a high-horsepower tractor and a non-road vehicle, in particular to a continuously variable transmission system of a dual-clutch differential split confluence. Background technique [0002] The existing non-road transmission system is divided into manual shift system according to the shift mode; stepped power uninterrupted automatic shift system; stepless continuous CVT (continuously variable transmission) shift system. [0003] 1. Manual shift system: [0004] A shift system consisting of a manual shift lever, a shift shaft and a shift fork; when shifting, the system needs to disengage the main clutch, cut off the power of the gearbox input shaft, manually operate the gear selection and shift process, and need to stop and shift during operation. block. [0005] 2. Power uninterrupted automatic shift system: [0006] Refers to the shifting process of the vehicle under the conditi...
