Accompanying drawing explanation
Fig. 1 is the structural representation of integral type transmission case for the utility model electric tractor.
Embodiment
Below by accompanying drawing, the utility model is further described.As shown in Figure 1, this kind of electric tractor integral type transmission case device, the walking and the power output that adopt two kinds of transmission devices of two drive motor to be respectively electric tractor provide power; Walking transmission device B be take the mode of engaging sleeve gearshift and is divided into high and low two sections and provides power as tractor walking; The walking output shaft 1 that transmission case leads to back axle is that power output actuator A and walking transmission device B share; Mechanism housing and rear axle housing body are integrated sandwich type element 2, and the mounting point of reserved power take-off D.
The walking output shaft 1 of walking transmission device B rear end is connected with the bevel gear wheel C1 in back axle differential mechanism C; Before power output in power output actuator A, jack shaft A3 is connected with the power output input shaft D1 in power take-off D; Duplicate gear A6 in power output actuator A is sleeved on walking output shaft 1; Sliding gear collar B8 in walking transmission device B is arranged on walking output shaft 1 by spline.
In power output actuator A, power output input shaft A4 is connected with power output drive motor A1 by spline; Power output driving gear A5 is arranged on power output input shaft A4 by spline; Duplicate gear A6 and power output driving gear A5 engagement, be sleeved on walking output shaft 1; Power output driven gear A7 and duplicate gear A6 engagement, and be arranged on the front jack shaft A3 of power output by spline; Before power output, jack shaft A3 front end is connected with oil pump A2, and rear end is connected with the power output input shaft D1 in power take-off D.
In walking transmission device B, walking input shaft B2 is connected with travel driving motor B1 by spline; Normal engagement driving gear B3 is arranged on walking input shaft B2 by spline; Normal engagement driven gear B4 and normal engagement driving gear B3 engagement, and be arranged on walking jack shaft B5 by spline; Driving gear
b9with driven gear B10 engagement, and be arranged on walking jack shaft B5 by spline; Driving gear B6 and driven gear B7 engagement, and be arranged on walking jack shaft B5 by spline; Driven gear B7 and driven gear B10 are sleeved on walking output shaft 1; Walking output shaft 1 is connected with the bevel gear wheel C1 in back axle differential mechanism C.
