The twin-motor double-gear electric driving system disclosed by the utility model is simple in structure, can shift gears without the clutch, and is easy to implement; and the optimal combination of the dynamic property and the economy can be achieved under the control of the drive combination of two motors.

Description

Two grades of power drive systems of a kind of double-motor
Technical field
The utility model relates to the electric vehicle engineering field, especially relates to two grades of power drive systems of a kind of double-motor.
Background technology
Existing pure electronic power drive system scheme, be divided into two kinds according to the speed change scheme, a kind of is the drive system that adopts the one pole speed reduction gearing, do not have change speed gear box, adopt the single-stage variable gear to realize slowing down, the speed governing by motor realizes infinite speed variation, but because without speed changing function, be difficult to take into account the contradiction of pick-up time and maximum speed, and when operating mode operation commonly used, be difficult to optimize the operation interval of motor to improve drive-train efficiency; Another scheme is to adopt the drive scheme of the multi-speed gear boxes such as 2 grades or 3 grades, this scheme can be good at addressing the above problem, but so that driving system structure is complicated, cost increases. and gear shift needs clutch control more, can increase shifting shock, reduce the vehicle riding comfort energy.
The utility model content
The technical matters that the utility model solves is to solve the problem that battery-driven car dynamic property and economy are taken into account.
In order to overcome the above problems, the utility model provides a kind of double-motor two grades of power drive systems, comprising: the first motor, the second motor, 1 grade of gear cluster, 2 grades of gear clusters, main reduction gear, diff, free-wheel clutch; Wherein the first motor is connected with 1 grade of gear, and the second motor is connected with 2 grades of gear clusters; Free-wheel clutch is between the first motor output shaft and solid output shaft; The first motor and the second motor are coaxial output; 1 grade of gear cluster with are connected grade gear cluster and all are connected with main reduction gear, motor-driven moment is by the change gear group, main reduction gear, diff are transferred to output shaft and drive wheel.
Further, as preferably, described the second motor output shaft is hollow shaft, with the together coaxial output of the first motor output solid axle empty set.
The utility model beneficial effect, simple in structure, no-clutch can be realized gear shift, is easy to realize, the driving combination control by two motors can realize the optimal combination of dynamic property and economy.
Description of drawings
When considered in conjunction with the accompanying drawings, by the following detailed description of reference, can more completely understand better the utility model and learn easily wherein many advantages of following, accompanying drawing described herein is used to provide further understanding of the present utility model, consist of a part of the present utility model, illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of to improper restriction of the present utility model, wherein:
Fig. 1 double-motor folk art term power drive system example structure figure.
The specific embodiment
Referring to figure embodiment of the present utility model is described.
For above-mentioned purpose, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, two grades of power drive systems of a kind of double-motor comprise: 4,2 grades of gear clusters 3 of 2,1 grades of gear clusters of the first motor 1, the second motor, main reduction gear 5, diff 6, free-wheel clutch 10; Wherein the first motor 1 is connected 4, the second motors 2 and is connected 3 with 2 grades of gear clusters with 1 grade of gear; The first motor 1 and the second motor 2 are coaxial output; Free-wheel clutch 10 is between the first motor 1 output shaft and solid output shaft; Shelves gear cluster 4 with are connected grade gear cluster 3 and all are connected with main reduction gear 5, motor-driven moment is by change gear group 3,4, main reduction gear 5, diff 6 are transferred to output shaft 7 and drive wheel.Described the second motor output shaft 8 is hollow shaft, with the together coaxial output of the first motor output solid axle 9 empty sets.
When type of drive of the present utility model is low speed and high pulling torque driving demand, the first motor 1 and the second motor 2 drive simultaneously, strengthen dynamic property, operating mode commonly used drives demand or runs at high speed when driving, then the second motor 2 drives separately, the machine operation interval can be optimized to scope during the efficient operation, obtain efficient drive-train efficiency, thus extending driving range.
Owing to adopt Dual-motors Driving, the first motor 1 is the dynamic property drive motor, the main satisfied climbing equidynamic that accelerates drives demand, require to mate according to dynamic property, the second motor 2 is the economy drive motor, be operating mode drive motor commonly used, mate at its high efficiency range according to the operation point commonly used of motor, taken into account dynamic property and economy requirement; And by the Proper Match of a grade and second gear speed ratio, taken into account the contradiction of pick-up time and maximum speed in the dynamic property.
As mentioned above, embodiment of the present utility model is explained, but as long as not breaking away from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the present utility model.
