Description
Technical field
The invention belongs to transmission for vehicles technical field, particularly relate to a kind of many gear double-clutch speed changers and vehicle.
Background technique
Two clutch type automatic transmission is integrated in a case of transmission by two gearboxes and two clutches, two inside and outside input shafts connected together rotationally are connected with one of them clutch respectively, two input shafts transmit the power of two gearbox speed groups respectively, by automatically switching between two clutches thus completing gearshift program, therefore the persistency of shift process medium power can be realized, namely power is interrupted at shift process, overcome the shortcoming of AMT shift shock, vehicle is in shift process, the power of motor can be delivered to wheel all the time, gearshift rapidly steadily, not only ensure that the acceleration of vehicle, and no longer produce due to the abrupt deceleration situation that causes of shifting gears due to vehicle, also the travelling comfort of vehicle operating is improved greatly.But, double-clutch automatic transmission due to routine mostly is to adopt double output shaft or single output shaft and adopt and shares driving gear or linear arrangement gear train, therefore its axial dimension is longer, so for the such vehicle of front transverse engine, front-wheel drive, particularly compact car, because its installing space is restricted, above-mentioned speed changer is more difficult employing just, and due to the gear of its speed change less, make that motor is more difficult is operated in optimum working zone, thus the power character of car load and Economy are had a negative impact.
Publication number is that the Chinese patent application of CN103711845A discloses and a kind of keeps off double-clutch speed changer more, it comprises: the outer input shaft nested together and interior input shaft, described interior input shaft is connected with power source by first clutch, described outer input shaft is connected with power source by second clutch, and described outer input shaft and interior input shaft are equipped with at least one driving gear; Output shaft in output shaft and the second outer output shaft and second of nesting together in nest together first outer output shaft and first, in described first, output shaft is provided with the first output gear engaged with differential gear, in described second, output shaft is provided with the second output gear engaged with differential gear, and in described first outer output shaft, first, in output shaft, the second outer output shaft and second, output shaft is equipped with at least one driven gear of engaging corresponding to described driving gear; Switching element, described switching element can control the joint between different driving gear and between different driven gear, with the speed ratio making speed changer export multiple different gear.Control the joint between different driving gear and between different driven gear by switching element, like this, 17 forward gears can be realized at most and one reverse gear.
But, in CN103711845A, because the first output gear and the second output gear to be connected in first in output shaft and second on output shaft, and switching element is only control the joint between different driving gear and between different driven gear, thus, after the driven gear of certain gear on the first outer output shaft and the second outer output shaft engages with the driving gear of the corresponding gear on interior input shaft or outer input shaft, the rotation of the first outer output shaft and the second outer output shaft can not be directly passed to the second output gear in the first output gear and second in first on output shaft on output shaft, but need the driven gear by other gear and driving gear, like this, cause at some gear, oversize to the power transfer path of the first output gear or the second output gear by power source (motor or motor), the transmission efficiency of speed changer is caused to reduce, and, the long power transfer path oversize reaction time that also can increase gearshift, affect the travelling comfort of vehicle operating.
