Problems solved by technology
All kinds of transmissions have certain applications on off-road vehicles, but automatic transmissions such as DCT and CVT are mostly used in vehicles driving in cities and on roads, mainly for the comfort of the occupants, and for vehicles driving in the field for a long time , the assembly of these transmissions cannot well meet the power requirements
Vehicles equipped with traditional manual mechanical transmissions have high requirements on the driver's driving skills when starting and shifting gears, and the rate of operational errors is also high. The driver is prone to fatigue and the vehicle operation comfort is poor.

The invention relates to a DCT / AMT transmission of a cross country vehicle and a control method thereof. The DCT / AMT transmission comprises an automatic gearbox, a main reducing gear, a semi-axis and a hub reduction gear, the automatic gearbox comprises a clutch, a synchronizer, an odd shift output shaft, an even shift output shaft, a transmission gear, a hydraulic operation and control mechanism and a control unit TCU; the clutch comprises a first clutch, a second clutch and a third clutch; the hub reduction gear uses a planetary line structure. The DCT / AMT transmission of the cross country vehicle can select the shifting type of the gearbox according to the road situation, and the shifting mode includes DCT / AMT shifting mode. The DCT / AMT transmission of the cross country vehicle is high in transmission efficiency, capable of meeting the dynamic property, economical property and operation comfort requirements of the cross country vehicle, capable of enabling the vehicle to meet different road requirements, and capable of realizing the equal wearing of front and rear tires of the vehicle and avoiding the tire exchange; the gearbox can be refitted based on an MT production line, the succession is good, and the production cost is low; the transmission scheme can be used for the cross country vehicle.
Description
technical field [0001] The invention relates to the technical field of automatic transmissions, in particular to a DCT / AMT transmission device and a control method for off-road vehicles capable of realizing switching between DCT and AMT. Background technique [0002] At present, the transmission technology is developing rapidly, and the automatic transmission technology has been very mature and has been widely used. Automatic transmissions mainly include hydraulic automatic transmissions, electromechanical automatic transmissions, continuously variable transmissions, and automatic transmissions. They have been assembled on different models, but each automatic transmission has certain advantages and disadvantages. All kinds of transmissions have certain applications on off-road vehicles, but automatic transmissions such as DCT and CVT are mostly used in vehicles driving in cities and on roads, mainly for the comfort of the occupants, and for vehicles driving in the field for ...
