Abstract
A double-power driving device is provided with a number I motor and a number II motor. An output shaft of the number I motor is connected with a speed changing box input shaft of a maximum moment output gear set though a flywheel and a clutch, a speed changing box output shaft is connected with an electric car main axle through an output gear to form a manual speed changing mechanism, an output shaft of the number II motor is connected with an input shaft of a hydraulic pusher, an output shaft of the hydraulic pusher is connected with the electric car main axle through a differential gear to form a hydraulic assisting mechanism, and the manual speed changing mechanism and the hydraulic assisting mechanism form the double-power driving device. The flywheel, the clutch, the speed changing box and the hydraulic pusher are arranged in a power box. The moment output by the differential gear can help improving the rotation moment of the electric car main axle. Under the situation that the output power of motors is not improved, the maximum moment gear group can increase output moment. By means of the double-power driving device, the rotation moment of the electric car main axle can be increased under the common action of the differential gear and the output gear. Therefore, driving and climbing capacity of an electric car on muddy roads is improved.
Description
Technical field
The utility model relates to a kind of vehicle power output unit, particularly relates to a kind of Power Drive Unit of miniature electric vehicle.
Background technology
Existing mini electric vehicle, engine installation is made up of storage battery group, controller, motor.Electric vehicle running provides electric flux to produce torque through controller to motor by the storage battery group and accomplishes.During the battery-driven car cruising; The electric energy that storage battery group on the vehicle provides is a definite value; Can only weaken in other words and can not strengthen, so just can cause battery-driven car on uneven, muddy unreal and road surface, abrupt slope, the silt car to occur, be i.e. the mud situation of wheel that sticks because of outputting power is not enough.
If think not produce under the above-mentioned situation silt car, the storage battery group could produce bigger output torque must for the motor more electric energy.At present; With the typing battery-driven car; The electric energy reserves of storage battery group are fixed, receive the restriction of vehicle and power output structure relation, change the storage battery model; Increasing the storage battery capacity has been difficult, and the silt car appears in the mini electric vehicle that is to say existing typing when hollow mire and abrupt slope road traveling be a very big weakness.
The utility model content
The purpose of the utility model is exactly to overcome the existing not enough shortcoming of mini electric vehicle outputting power, provides a kind ofly under the situation that does not increase the storage battery capacity, can export bigger moment and dual-power driving device simple in structure.
The purpose of the utility model can realize.The utility model dual-power driving device comprises the motor on the existing vehicle; The utility model dual-power driving device is characterised in that: said motor comprises I number and II number two motors; The input shaft that is connected change speed gear box by the output shaft of said I motor through flywheel with power-transfer clutch; Establish maximum torque output gear wheels in the said change speed gear box; The output shaft of said change speed gear box connects the battery-driven car main axle through output gear and constitutes hand gear mechanism; Connect the input shaft of fluid power pusher by the output shaft of said II motor, the output shaft of said fluid power pusher connects the battery-driven car main axle through differential gear and constitutes the servomechanism that surges, and said hand gear mechanism and the said servomechanism that surges constitute said dual-power driving device.
The utility model dual-power driving device, wherein said flywheel, power-transfer clutch, change speed gear box and fluid power pusher place headstock.
The utility model dual-power driving device difference from prior art is that the utility model dual-power driving device is the improvement that the prior art battery-driven car is carried out; Improvement project is: in the outputting power device, set up one and overlapped the servomechanism that surges, the torsion of the differential gear output of the servomechanism that surges can be assisted the rotating torque that improves the battery-driven car main axle; In change speed gear box, set up the torque peak gear cluster, under the situation that does not improve the motor horsepower output, output gear can improve the output torque of change speed gear box; Under differential gear and output gear combined action, battery-driven car main axle rotating torque is increased.Use the utility model, greatly improved battery-driven car and gone and hill climbing ability, when on flat road, going at muddy road surface; Can cut off the electric current supply of fluid power impeller motor; Use single action power to drive, just can avoid unnecessary current draw, more energy-conservation.
Be described further below in conjunction with the dual-power driving device of accompanying drawing the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model dual-power driving device.
Among the figure.1 I motor, 2 II motors, 3 flywheels, 4 power-transfer clutchs, 5 change-speed boxs, 6 fluid power pushers, 7 torque peak gear clusters, 8 high speed gear groups, 9 headstocks, 10 output gears, 11 differential gears, 12 battery-driven car main axles.
The specific embodiment
As shown in Figure 1, the utility model dual-power driving device is the improvement to the prior art battery-driven car, and the utility model dual-power driving device comprises the motor on the existing vehicle.Be provided with I motor 1 and II motor 2 in the utility model dual-power driving device.Pass through flywheel 3 is connected change speed gear box 5 with power-transfer clutch 4 input shaft by I motor 1 output shaft, the output shaft of change speed gear box 5 connects battery-driven car main axles 12 through output gear 10 and constitutes hand gear mechanisms.Manual transmission is helped in change speed gear box 5 designs.Be provided with five groups of variable gears in the change speed gear box 5, wherein change-gear set 7 is the maximum torque output gear wheels of repacking, and high speed gear group 8 is gear clusters of original technology.Five groups of gears in the manual control change speed gear box can change the output revolutions of output shaft respectively, change the electric vehicle running state.Also installed the input shaft that is connected fluid power pusher 6 by the output shaft of II motor 2 in the utility model additional, the output shaft of fluid power pusher 6 connects the servomechanism that surges that the battery-driven car drive sprocket axle constitutes through differential gear 11.The dual-power driving device of the hand gear mechanism and the servomechanism formation the utility model that surges.
In the utility model dual-power driving device, flywheel 3, power-transfer clutch 4, change speed gear box 5 and fluid power pusher 6 are placed in the headstock 9.
Reequiped the battery-driven car of the utility model dual-power driving device; Go when muddy uneven road surface or climbing; Can handle change speed gear box 5; Make 7 work of maximum torque output gear wheels, the moment of torsion output valve during 7 work of maximum torque output gear wheels is seven times that battery-driven car is not reequiped preceding acrotorque output valve, has greatly improved the horsepower output of change speed gear box 5.If the horsepower output of this moment still is apparent not enough, or be when protecting hand gear mechanism, but starter motor 2 makes 6 work of fluid power pusher, the torsion of fluid power pusher 6 outputs makes differential gear 11 help output gear 10 to work.Under the situation of output gear 10 and differential gear 11 common outputting torsions, the driveability of battery-driven car is improved.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
