It is damped condition when making.
The work process of the present embodiment is as follows：Control system detects car speed, carries out gear according to predetermined speed and cuts
Change.Input shaft 1 is power intake, and output shaft 6 is gear II 12 meshed gears I 26 on clutch end, with input shaft 1
Rotate with gear IV 37, drive pump impeller shaft I 23 and pump impeller shaft II 33 and then drive coupling device pump impeller 221 and converter pump 241
Rotate, when vehicle launch and low cruise, the oil-filled work of torque-converters 24, mechanical energy is transformed into high-voltage high-speed liquid energy, then
Pass to respective driven pulley turbine, now for the oil-filled work of a gear；When vehicle drives to moderate speed range, control system is cut
Change oil road so that the oil-filled work of coupling device I 22, torque-converters 24 oil extraction simultaneously, now for the oil-filled work of two gears；Work as locomotive operation
To coupling device II 32 oil-filled work during more speed scope, coupling device I 22 oil extraction simultaneously, it is the oil-filled work of three gears.Due to power
Transmittance process in, the number of teeth of gear III 36 is more than the number of teeth of reverse transition gear 4, is speed increasing gear pair, therefore output shaft 6 can
To rotate with higher speed, realize three gear work.In each gear hydraulic power unit handoff procedure, oil extraction is entered with oil-filled simultaneously
Row is not it is ensured that pull strength interrupts.During hydraulic braking, the equal oil extraction of all traction hydraulic power units does not work；The oil-filled work of hydraulic brake
Make, realize the braking of vehicle.Forward direction described in the present embodiment be output turn to identical with entering defeated steerings, be reversed output steering and
Input turns to contrary.
The work of traction working condition each gear is as follows：
When 0-1 keeps off work, power transmission is realized in：
