ABSTRACT:
A rear suspension for battery powered on-road scale model car of the type having a straight rear axle and a nonindependent rear suspension is disclosed. The model car includes a chassis having a central longitudinal axis with a centrally located battery pack. A pair of remotely steerable wheels are pivotably affixed to the chassis front end. A motor pod pivotably supports a pair of rear wheels interconnected by a straight rear axle and includes a mechanism for attaching an electric drive motor. The rear suspension elastically attaches the motor pod to the chassis for limited vertical bounce movement and limited torsional roll movement of the motor pod relative to the chassis. The rear suspension components are spaced sufficiently from the battery pack to provide clearance for a row of batteries oriented centrally along the chassis. The central battery design minimizes mass moment of inertia of the model car measured about the longitudinal axis resulting in improved maneuverability.
