Abstract

A first link mechanism of a suspension is provided at a rear end portion of a vehicle for connecting a drive wheel to a vehicle body, so that the drive wheel performs vertical movements relative to the vehicle body via the first link mechanism. In addition, a shock absorber is attached to a lower arm of the first link mechanism for resiliently supporting the drive wheel relative to the vehicle body. Furthermore, a second link mechanism is provided on the upper arm and the lower arm of the first link mechanism which performs symmetrically vertical movements relative to the vertical movements of the first link mechanism, and a motor is integrally attached to the second link mechanism, whereby inertia energy resulting from the vertical movements of the drive wheel and inertia energy resulting from the vertical movements of the motor are made to be offset against each other.

Claims12

Dependent claims

A vehicle with electric motors comprising:

a vehicle body,
electric motors functioning at least as drive sources,
drive wheels which are rotated to be driven by the electric motors,
suspensions each having a resilient member adapted for absorbing vibrations transmitted to the vehicle body from the drive wheel and resiliently supporting the drive wheel relative to the vehicle body and a first link mechanism portion adapted for allowing the drive wheel to move vertically relative to the vehicle body and supporting the drive wheel on the vehicle body, and
second link mechanism portions each connected to a vehicle body side support portion of the first link mechanism portion and adapted for performing symmetrically vertical movements relative to the vertical movements of the drive wheel,
wherein each electric motor is fixedly attached to each respective second link mechanism portion, and
wherein each electric motor is disposed on an opposite side of the resilient member relative to a corresponding drive wheel.
