In power output actuator, Power output input shaft is connected with Power output drive motor by spline; Power output driving gear is arranged on Power output input shaft by spline; Duplicate gear engages with Power output driving gear, is sleeved on walking output shaft; Power output driven gear engages with duplicate gear, and to be arranged on before Power output on jack shaft by spline; Before Power output, jack shaft front end is connected with oil pump, and rear end is connected with the Power output input shaft in power take-off.
In walking transmission device, walking input shaft is connected with travel driving motor by spline; Normal engagement driving gear is arranged on walking input shaft by spline; Normal engagement driven gear with often engage driving gear and engages, and be arranged on by spline and walk on jack shaft; Second driving gear engages with the second driven gear, and is arranged on walking jack shaft by spline; First driving gear engages with the first driven gear, and is arranged on walking jack shaft by spline; First driven gear and the second driven gear are sleeved on walks on output shaft; Walking output shaft is connected with the bevel gear wheel in back axle differential mechanism.
Sliding gear collar is arranged on walking output shaft by spline, and axially can horizontally slip along walking output shaft.
Following good effect can be reached: electric tractor integral transmission case adopts above-mentioned arrangement, and drive path is clear, compact structure after the present invention adopts technique scheme.Both the power of travel driving motor can be realized to the transmission of electric tractor back axle the requirement speed of a motor vehicle that farming section requires the speed of a motor vehicle and transport section, the drive motor transmission of power that also can output power is to power take-off and oil pump.Adopt this kind of electric tractor integral transmission case, farthest can not only play the characteristic of motor, thus realize two section stepless change; The manufacturing efficiency of electric tractor more can be made to be improved, and to operate easy to use, to meet the manufacture and usage needs of electric tractor.Electric tractor integral transmission case is simple and compact for structure, decreases part kind and quantity, reduces cost of production.
Accompanying drawing explanation
Fig. 1 is the structural representation of electric tractor integral transmission case of the present invention.
Embodiment
Below by accompanying drawing, the present invention is further illustrated.As shown in Figure 1, this kind of electric tractor integral transmission case device, adopts two drive motor, two kinds of transmission devices to be respectively the walking of electric tractor and Power output provides power; Walking transmission device B is divided into high and low two sections to walk for tractor in the mode that engaging sleeve shift gears provides power; 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 engages with Power output driving gear A5, is sleeved on walking output shaft 1; Power output driven gear A7 engages with duplicate gear A6, and to be arranged on before Power output on jack shaft A3 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 with often engage driving gear B3 and engages, and be arranged on by spline and walk on jack shaft B5; Second driving gear
b9engage with the second driven gear B10, and be arranged on walking jack shaft B5 by spline; First driving gear B6 engages with the first driven gear B7, and is arranged on walking jack shaft B5 by spline; First driven gear B7 and the second driven gear B10 is sleeved on and walks on output shaft 1; Walking output shaft 1 is connected with the bevel gear wheel C1 in back axle differential mechanism C.
Sliding gear collar B8 is arranged on walking output shaft 1 by spline, and axially can horizontally slip along walking output shaft 1.
The power of electric tractor is as follows through electric tractor integral transmission case bang path:
Farming section: sliding gear collar B8 slides backward, engages with the spline joint tooth of the second driven gear B10.Power, by travel driving motor B1 → walking input shaft B2 → normal engagement driving gear B3 → normal engagement driven gear B4 → walking jack shaft B5 → the second driving gear B9 → the second driven gear B10 → sliding gear collar B8 → walking output shaft 1 → back axle differential mechanism C, is then realized the walking of electric tractor by traveling gear and wheel.
Transport section: sliding gear collar B8 forward slip, engages with the spline joint tooth of driven gear B7.Power, by travel driving motor B1 → walking input shaft B2 → normal engagement driving gear B3 → normal engagement driven gear B4 → walking jack shaft B5 → the first driving gear B6 → the first driven gear B7 → sliding gear collar B8 → walking output shaft 1 → back axle differential mechanism C, is then realized the walking of electric tractor by traveling gear and wheel.
Power output: power by jack shaft A3 → power take-off D before Power output drive motor A1 → Power output input shaft A4 → Power output driving gear A5 → duplicate gear A6 → Power output driven gear A7 → Power output, to realize Power output.
Drive oil pump: power by jack shaft A3 → oil pump A2 before Power output drive motor A1 → Power output input shaft A4 → Power output driving gear A5 → duplicate gear A6 → Power output driven gear A7 → Power output, with realize drive oil pump.
As can be seen here, electric tractor integral transmission case by the power of travel driving motor to tractor rear axle transmission, can realize farming section or transport section; And electric tractor integral transmission case can output power, the power of drive motor is to power take-off and oil pump transmission, realizes Power output and drives oil pump.
