What the present invention obtained by adopting the above technical scheme has the beneficial effect that speed changer has gearshift function, reduction gearbox of shifting gears
Two grades of handoff functionalities of high, low speed with large speed ratio.When shift reduction gearbox is in high gear, engine power passes through speed changer
Conversion speed regulation after, pass to shift reduction gearbox, shift reduction gearbox can export power with top gear, and engineering truck can be at this time
It runs at high speed under normal mode.When shift reduction gearbox is in large speed ratio low gear, shift reduction gearbox can transmit speed changer
Power-conversion output is the power of ultra-low speed big torsional moment, and engineering truck can carry out operation behaviour under Ultra-Low Speed driving status at this time
Make.
In the operating condition, power is successively passed to the 4th transmission shaft, rear axle from third transmission shaft by brake, is realized complete
Bridge driving.When engineering truck high-speed travel state, brake can disconnect the power that reduction gearbox of shifting gears is transmitted to third transmission shaft,
To disconnect the power input of rear axle, bridge list bridge driving before realizing.In engineering truck parking, the braking work of brake can be passed through
The rotation of third transmission shaft and the 4th transmission shaft can be limited, to realize parking brake function.
