Abstract

The invention provides a hybrid power electrical transmission device of a caterpillar vehicle. The hybrid power electrical transmission device comprises an engine, a starting engine, a split planet bar, a forward and reverse gear mechanism, a left driving motor, a right driving motor, a left bus bar, a right bus bar, a cross shaft, a left parking brake, a right parking brake, a left drive and a right drive, wherein the engine is used for providing a first power source for driving the vehicle to run; the starting engine is used for starting the engine and generate power; the split planet bar is used for decomposing output of the engine into running power current for running and power generation power current for power generation; the forward and reverse gear mechanism is used for realizing switching of the rotation direction of the running power current and switching of high and low gears, and comprises a front bevel gear, a forward gear bevel gear, a reverse gear bevel gear, a forward gear planet bar, a forward gear brake, a reverse gear planet bar and a reverse gear brake; the left driving motor and the right driving motor are used for providing a second power source for driving the vehicle to run; the left bus bar and the right bus bar are used for bus and differential speed of two paths of power current for bypassing and steering; and the cross shaft is used for power transfer between the forward and reverse gear mechanism and the left bus bar as well as the right bus bar.

Description

technical field [0001] The invention relates to a vehicle power transmission device, in particular to a hybrid electric transmission device for a crawler vehicle, in particular to a compact hybrid electric transmission device for a crawler vehicle. Background technique [0002] Hybrid electric transmissions for tracked vehicles should provide an optimal weight, volume and cost technical solution combined with high mobility of the vehicle. In particular, hybrid electric transmissions should have high power density, be compact and take up little space for overall vehicle layout. [0003] US Patent Application Publication No. US2007 / 0012505A1 discloses a hybrid electric transmission device for tracked vehicles, which includes driving motors and parking brakes arranged symmetrically and laterally on both sides of the car body, and consists of a steering motor arranged longitudinally, a pair of bevel gears, two A controllable differential steering mechanism composed of two bus b...
