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.
