It further include a free pulley 2, free pulley 2 is set between driving wheel 1 and driven wheel 3, by driving wheel 1 and driven wheel
3 carry out transmission connection.Free pulley 2 is set, driving wheel 1 and the rotation direction of driven wheel 3 can be made to be consistent, conducive to power
Transmission and distribution.
The rear output shaft 7 is also connected with rear transmission fork 82, outputs power to vehicle rear axle.
The rear output shaft 9 is also connected with forward pass moving fork 81, outputs power to bridge before vehicle.
In 9 one end of front output shaft insertion sun gear 6, it is fixedly connected with sun gear 6；9 other end of front output shaft is equipped with
External gear forms gear with the interior hub of clutch 11 and is cooperatively connected.
The gear ring 4 is boss structure, is provided with two circle internal gears, wherein a circle internal gear and planet carrier 5 are cooperatively connected,
The external gear being arranged on the outside of another circle internal gear and rear output shaft 7 is cooperatively connected.
It further include a differential casing 10, driven wheel 3, driven wheel 3, rear output shaft 7, front output shaft 9 and clutch
11 are installed in differential casing 10.
The clutch 11 is multiple-piece friction manipulation part, when clutch 11 combines, front output shaft 9 and rear output shaft 7 into
The Torque distribution of the rotation of row indifferential, front output shaft 9 and rear output shaft 7 is 1:1, and when clutch 11 separates, front output shaft 9 is with after
Output shaft 7 carries out differential speed rotation, and front output shaft 9 and the Torque distribution of rear output shaft 7 are determined by the parameter of planet row 12.
The planet row 12 is simple planetary arrangement.
The inter-axle differential of this programme is suitable for the off-road vehicle that front-rear axle has specific torque to distribute.Used gear passes
Dynamic is Spur Gear Driving.Driving wheel 1 is reached by transmission output shaft to wherein power, driven wheel 3 is reached by free pulley 2,
Power reaches the planet carrier 5 of planet row 12 and the outer hub of clutch 11 through driven wheel 3.
