The technical problems to be solved in the utility model is the above-mentioned deficiency for prior art, provides the engine rear end hydraulic system driving structure that a kind of structure is simple, can improve hydraulic pump works stability and reliability.
The technical solution of the utility model is such: a kind of engine rear end hydraulic system driving structure, comprise motor, the bent axle of described engine rear end is provided with crank-driven gear, be respectively equipped with intermediate idler gear and hydraulic pump drive gear in the periphery of described crank-driven gear, be provided with oil hydraulic pump in the side of described hydraulic pump drive gear; Described crank-driven gear, intermediate idler gear and hydraulic pump drive gear composition gear train assembly, and be all positioned at engine rear end.
As improving further, described engine rear end is provided with motor transfer case.
Further, described crank-driven gear, intermediate idler gear and hydraulic pump drive gear are all positioned at described motor transfer case.
Further, be Spielpassung between described hydraulic pump drive gear coupling shaft both sides and bearing, and in described hydraulic pump gear, be provided with the two diametral pitch splined shafts be connected with oil hydraulic pump.
Further, described crank-driven gear and intermediate idler gear centre distance A are 134.28 ~ 234.28, and intermediate idler gear and hydraulic pump drive Gear center are 125.997 ~ 225.997 apart from B.
Further, described crank-driven gear and intermediate idler gear centre distance A are 184.28, and intermediate idler gear and hydraulic pump drive Gear center are 175.997 apart from B.
Beneficial effect
The utility model compared with prior art has the following advantages:
