The purpose of this utility model is achieved by the following technical solution: a kind of composite electric environmental protection motor omnibus, comprise the chassis, and be arranged on combustion engine, change-speed box, power converter and battery pack on the described chassis; The output of described combustion engine connects the first input end of described power converter by change-speed box; Described environmental protection motor omnibus also comprises electric device, it is characterized in that, described electric device comprises two motors, and wherein first motor is the single shaft motor, and second motor is dual-axle motor; Be coupling second input end of described power converter of the output of described dual-axle motor, the mouth of the input shaft order spindle motor of dual-axle motor; Described two motors are connected with described battery pack with circuit respectively.
A motor before the motor that above-mentioned the utility model environmental protection motor omnibus connects with two front and back replaces in the technology, make the volume and weight of motor can be dispersed in two positions on chassis, thereby it is excessive to have solved a heavy-duty motor volume and weight, is difficult to the problem of arranging on traditional chassis.It has the chassis ridgepole width requirement little, help motor be arranged in the chassis ridgepole inboard not with the afoul advantage of main reduction gear, simultaneously, also have the advantage that the connection form is simple, reliability is high.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the overall structure scheme drawing of an embodiment of composite electric enviromental protection automobile in 00239941.5 the utility application;
Fig. 2 is the chassis and the power system floor plan scheme drawing of an exemplary embodiments of the utility model composite electric environmental protection motor omnibus;
Fig. 3 motor connects form figure.
Composite electric enviromental protection automobile embodiment in 00239941.5 the utility application as shown in Figure 1 comprises combustion engine powered system A, cell power systems B, power converter 1 and main reduction gear 2; Described combustion engine powered system A comprises driving engine 3, power-transfer clutch 4 and the change-speed box 5 that order connects; The first input end of its power converter 1 connects the output of change-speed box 5, the output of the second input termination cell power systems B of power converter 1, the input end of the output termination main reduction gear 2 of power converter 1.Its cell power systems B comprises battery pack 6, having motor function under the electric energy effect the dynamoelectric machine 7 that has generator function under the mechanical energy effect and be connected in battery pack 6 and dynamoelectric machine 7 between and controller that its working condition is controlled; Second input end of the output termination power converter 1 of described dynamoelectric machine 7.Controller in battery pack 6 when dynamoelectric machine 7 power supply drives automobiles, according to automotive operation needs control motor horsepower output size, when the braking energy that produces at the energy more than needed of combustion engine powered system or automobile brake is converted into the electric energy of battery pack 6, dynamoelectric machine 7 is converted to the electrical generator state, to battery pack 6 chargings.
Further discover, the given embodiment of above-mentioned utility model is applicable to compact car, for the very big motorcoach of demanded power output (as the vehicle commander more than 10 meters, the motorcoach of weight more than 12 tons), because motor correspondingly has bigger volume and weight, can't on traditional chassis, install and arrange, if redesign and manufacturing chassis structure then can increase manufacturing cost.
The utility model composite electric environmental protection motor omnibus embodiment as shown in Figures 2 and 3 comprises chassis 20, is arranged on combustion engine 3, change-speed box 4, power converter 5 and battery pack 12 on the chassis 20; The output of combustion engine 3 connects the first input end of power converter 5 by change-speed box 4; Its electric device comprises two motors 1,2, and wherein motor 1 is the single shaft motor, and motor 2 is a dual-axle motor; The output shaft 15 of motor 2 connects second input end of power converter 5, the output shaft 17 of the input shaft 16 order spindle motors 1 of motor 2.
In the present embodiment, link by power-transfer clutch 7 between the output shaft 17 of motor 1 and the input shaft 16 of motor 2.The output shaft 17 of motor 1 links by the input end of unitor 11 with power-transfer clutch 7.The input shaft 16 of motor 2 links by the mouth of unitor 10 with power-transfer clutch 7.
