  • Patent number: 9859835
    Abstract: A cylindrical direct drive AC induction electric motor and an adapter plate comprises an electric power conversion design for liquid fueled vehicles. For front-wheel drive vehicles, an adapter plate replaces the spindle, the motor is bolted to the adapter plate and the vehicle wheel is bolted directly to the lug studs. For rear-wheel drive vehicles, each end of the rear axle is cut off. Using the adapter plate, the motor directly attaches to the end of the “pipe.” Also, a single-piece, trailer type axle could completely replace the axle. For independent rear suspension, the adapter plate bolts in place of the wheel bearing assembly and the wheel is attached to the motor. In all of these cases, the original internal combustion engine, transmission, and all other drive components, along with the exhaust system and fuel tank, are removed to make room for batteries and components of the electric drive system.

  • Patent number: 9834214
    Abstract: A suspension characteristic is changed depending on a travel state by a simple structure. An ECU uses a vehicle speed-spring constant setting part to calculate a target spring constant depending on a vehicle speed, and uses a spring constant-frequency setting part to calculate a set frequency corresponding to the target spring constant. An oscillation input calculation part generates a signal representing an oscillation input oscillating at the set frequency. A superimposition part sets a value acquired by superimposing the oscillation input on a target driving force to a new target driving force. As a result, the wheel exhibits a minute oscillation in a longitudinal direction, resulting in an input of the minute oscillation to a suspension bush. The suspension bush changes in a spring constant and a damping coefficient depending on the frequency of the input minute oscillation. As a result, the suspension characteristic can be changed.
