Description

A kind of variator

Technical field

The present invention relates to a kind of power transmission, more particularly to a kind of variator.

Background technology

Variator is to fix or stepping changes the gear drive of output shaft and input shaft gear ratio, and variator is extensive For lathe, vehicle and other need the machine of speed change, variator has variable ratio, realizes reverse travel, interrupts power Transmission and the function of realizing neutral gear.The variator using on loader now is mostly using being rigidly connected it is impossible to according to outer load The difference of lotus automatically adjusts the output of moment of torsion and rotating speed, can produce and can produce violent vibration, electromotor is easy during external applied load change Flame-out, engine power cannot fully play and utilize, and loader adaptivity is poor.

Content of the invention

The problem to be solved in the present invention is for problem above, provides one kind automatically can be automatically adjusted according to external applied load change The variator of the output of moment of torsion and rotating speed.

For solving the above problems, the technical solution adopted in the present invention is: a kind of variator, including casing, described casing Inside it is provided with driving shaft, output shaft, the first intermediate propeller shaft, the second intermediate propeller shaft and the 3rd intermediate propeller shaft, described active Twin-turbine torque converter, the first driving gear and the second driving gear be provided with axle, described first intermediate propeller shaft, second Intermediate propeller shaft and the dead in line of the 3rd intermediate propeller shaft, described first intermediate propeller shaft and the second intermediate transmission through-drive are even Connect, described first intermediate propeller shaft be provided with freewheel clutch, the first driven gear and the second driven gear, described surmount from Clutch is connected with the first driven gear and the second driven gear respectively, described second intermediate propeller shaft is provided with planetary gear from Clutch, described 3rd intermediate propeller shaft is provided with friction disk clutch and the 3rd driving gear, described 3rd driving gear with Friction disk clutch connects, and described output shaft is provided with the 3rd driven gear, described freewheel clutch and planetary gear clutch Device is in transmission connection, and described friction disk clutch is in transmission connection with planet gear clutch and the 3rd intermediate propeller shaft respectively, described First driving gear and the engagement of the first driven gear, described second driving gear and the engagement of the second driven gear, the described 3rd is main Moving gear and the engagement of the 3rd driven gear.

A kind of concrete prioritization scheme, described first intermediate propeller shaft and the 3rd intermediate propeller shaft are located at the second intermediate propeller shaft Two ends.

The present invention takes above technical scheme, and when having the advantage that use, engine power is through double turbine hydraulic moment changeables Device exports freewheel clutch, is then passed to planet gear clutch, then transfers power to defeated through friction disk clutch Shaft, power exports through output shaft, and using twin-turbine torque converter, variator can automatically adjust according to external applied load change Moment of torsion and the output of rotating speed, will not produce violent vibration during external applied load change, electromotor is difficult to stop working, and engine power obtains Fully play and utilize, loader adaptivity is good.

The invention will be further described with reference to the accompanying drawings and examples.
