Description
Technical field：
The invention belongs to gearbox technical field, it is related to a kind of automotive transmission, it is especially a kind of with automatic clutch
Automobile gearbox, occasion is prepared for automobile.
Background technology：
Speed changer is to lean on several gears to different drive ratios to realize changing torque and rotating speed, mainly by gear drive
Deceleration, increase torque effect.Two gears are meshed, and one tooth of driving gear promotes one tooth of driven gear, such as actively small
The number of teeth of gear is 8, and the number of teeth of driven gear wheel is 16, then pinion rotation 1 is enclosed, and gear wheel can only turn over half-turn, so one
Gear drive can just be reached reduces the effect of rotating speed.Meanwhile, the active force on two gear teeth contact surfaces is equal, root
Understand that under conditions of active force is equal, little gear radius is small, and torque is small according to the principle of " active force multiplies radius equal to torque ",
Gear wheel radius is big, and torque is also big, therefore, in little gear drive gear wheel, the rotating speed of gear wheel can be both reduced, again can be with
Increase the torque of gear wheel.The radius of actual gear and its number of teeth are a proportional relations, therefore, if disregard be driven
Frictional resistance in journey, the then multiple of the multiple of canine tooth wheel speed reduction, that is, torque increase.Make to realize that vehicle is actual
With the change torque and chronotropic action that are required under operating mode, speed changer must be made up of the multipair gear of different drive ratios.When a pair
During gear transmission power, other engagements that are out of gear.In the prior art, Chinese patent CN100430624C disclose it is a kind of double from
Clutch formula manual transmission, including the input shaft with each clutch, the countershaft being be arranged in parallel with these input shafts；It is arranged on
The gear train of the odd gear group between the rearward end and countershaft of the first input shaft；It is arranged between the second input shaft and countershaft
The gear train of even gear hyte；Output shaft concentric with the rear end of the first input shaft and adjacent；Be arranged on the first input shaft
The synchronizer for being directly coupled gear to provide between rear end and countershaft, odd gear group includes directly being coupled gear.First is defeated
The rearward end and countershaft for entering axle can be rotated to support in the rotation supporting portion of agreement fixation wall of gear box casing, the rotation branch
Bearing portion is located at a gear combination being arranged in the final area of the first input shaft rearward end and is arranged on a gear train
Above and between another gear train adjacent with a gear train, its twin-clutch manual speed change for reducing FR- vehicles
The number of the fast ratio in device, so as to realize a contiguity speed than construction, but needs to trample clutch realization gearshift in driving procedure,
Clutch is frequently used, and the service life of clutch is quickly consumed, and shift hunting also reduces automobile in driving procedure
Driving experience；Chinese patent CN102678893B discloses a kind of manual transmission, including is input into the driving force from engine
Input shaft and the output shaft that is be arranged in parallel with the input shaft and the multiple teeth being set on the input shaft and output shaft
Wheel group, the gear train beyond the multiple gear train is high-grade including highest shelves gear group and most, the highest shelves gear group includes
The most high-grade drive gear and most high-grade driven gear of connection are engaged, wherein, the most high-grade drive gear empty set is described defeated
Enter on axle and can be fixed on the input shaft by with the rigidly connected lazy-tongs of the input shaft, it is described it is most high-grade from
Moving gear empty set on the output shaft and can by one-way clutch realize with the output shaft on and can be by unidirectional
Clutch is realized combining or separating with the output shaft, its taken in idle running and not it is most high-grade under conditions of realize safety slip
OK, to save fuel consumption, but need to trample clutch realization gearshift in driving procedure, clutch is frequently used, clutch
The service life of device is quickly consumed, and shift hunting also reduces the driving experience of automobile in driving procedure.
The content of the invention：
It is an object of the invention to the shortcoming for overcoming prior art to exist, seek a kind of automobile with automatic clutch of design
