One Motor Based Transmission system |
Conventional Type | Here, the PEV propulsion system consists of a clutch, a differential (D), a gearbox (G.B.) and an electric motor (M). This can be replaced by an ICE vehicle with a rear-engine-front-wheel system. This system is nothing but a replacement of the ICE, where an electric motor replaces an internal combustion engine. |
No Transmission Type: Rear-engine-Front-wheel (R.F.) | Here, fixed gearing is used instead of a clutch and gearbox. It is pretty similar to the conventional system. |
No Transmission Type: Front-engine-Front-wheel (F.F.) | Here, the differential, fixed gearing and the electric motor are placed in front of the vehicle. It is nearly the same as ICE with Front-engine-Front-wheel drive. |
Two Motors-Based Transmission System |
No differential Type | The differential is eliminated by two motors placed for two individual front wheels. Fixed gearing is applied with two engines attached with two front wheels. |
In-wheel type with fixed gear (F.G.) | This type is similar to the no-differential type, but the location of the motors is random. Electric motors are embedded in-wheel type in the wheels. |
In-wheel type without fixed gear (F.G.) | There is no mechanical gearbox in this system. The speed is directly proportional to the speed of the motor. |
