Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained on the premise of not making creative work, broadly fall into the scope of this utility model protection.
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as restriction of the present utility model.
As shown in Figure 1, the horizontally-opposed piston of two-stroke, the front end drive system of opposed-cylinder engine that the present embodiment provides include: engine body (not shown), electromotor basic device, primary transmission belt 1 and secondary transmission belt 2, wherein, electromotor basic device is arranged at the top of engine body.
As shown in Figure 1, the horizontally-opposed piston of two-stroke that the present embodiment provides, the topology view of the front end drive system of opposed-cylinder engine, electromotor basic device includes: crank pulley 3, cooling water pump 4, mechanical supercharger 5, and charging generator 6, wherein, cooling water pump 4 is provided with cooling water pump belt pulley 41, mechanical supercharger 5 is provided with mechanical supercharger belt pulley 51, charging generator 6 is provided with electromotor two-stage belt pulley 61, concrete, primary transmission belt 1 is sequentially connected with crank pulley 3, cooling water pump belt pulley 41 and the small-diameter wheels of electromotor two-stage belt pulley 61, secondary transmission belt 2 is sequentially connected with major diameter wheel and the mechanical supercharger belt pulley 51 of electromotor two-stage belt pulley 61.
After engine body starts, driven by engine crank pulley 3 rotates, cooling water pump belt pulley 41 and electromotor two-stage belt pulley 61 is driven to rotate by primary transmission belt 1, so that cooling water pump 4 and charging generator 6 work, simultaneously, secondary transmission belt 2 driving mechanical supercharger belt pulley 51 rotates, thus driving mechanical supercharger 5 works.
Due to the general competence exertion effect under the highest rotating speed of mechanical supercharger 5, this rotating ratio crank pulley 3 rotating speed is much higher, therefore mechanical supercharger 5 is connected with the major diameter wheel of electromotor two-stage belt pulley 61 by secondary transmission belt 2, makes rotating speed reach the normal operating rotational speed range of mechanical supercharger 5.
