The present invention relates to electric drivetrain kits for converting all-terrain vehicles into hybrid or electric vehicles. In exemplary embodiments, a conversion kit replaces an existing standard single motor and transmission drive system with a dual set-up including a motor for each rear wheel and a split transmission that houses two sets of gear reduction components in a single housing or an all-wheel configuration with two transmission sets (front and rear). Dual output shafts in each transmission set drive the wheels independently to provide the torque needed as required and demanded by each wheel. System electronics send signals to the motors and other components to manage the system and independently control each wheel.

This invention provides a device for increasing fuel economy which allows manual or automatic shutoff of an automobile engine under a first set of circumstances and restarting the engine under a second set of circumstances as well as control of the gear ratio selected by an automatic transmission and the rate of fuel delivery to the engine.

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

A platform to replace under-the-hood engine assembly of a conventional internal combustion engine vehicle. The platform includes a backbone frame and a tower frame secured to the backbone frame towards a vehicle front. The backbone frame and the tower frame are secured to chassis frame of the vehicle through a three point isolator mounting system. A plurality of electric drive components, such as battery radiators, electric-axle and high-voltage accessories cooling system radiator, air conditioning condenser, cooling fans, brake retarder, DC-DC voltage converter(s), HVAC compressor, inverter(s), low voltage batteries package, air compressor, pumps, etc. are secured to the backbone frame and the tower frame to support the electric motor of the electric vehicle.

A motor generator including a rotor and a motor output shaft that rotates integrally with the rotor, a connecting shaft capable of rotating coaxially with the motor output shaft, a hydraulic clutch interposed between the rotor and the connecting shaft, the hydraulic clutch switching transmission and non-transmission of torque between the rotor and the connecting shaft, and an auxiliary to be driven by rotation of the input shaft are provided. The input shaft of the auxiliary is mechanically linked with the connecting shaft.
