Abstract

A chassis assembly for an electrical vehicle is provided. The chassis assembly includes a main chassis, at least one main chassis wheel, a secondary chassis and at least one secondary chassis wheel. The at least one main chassis wheel is rotationally coupled to the main chassis about a main chassis rotational axis. A secondary chassis is pivotally coupled to the main chassis. The secondary chassis is configured and arranged to hold batteries that supply energy to an electric motor coupled to the main chassis. The at least one secondary chassis wheel is rotationally coupled to the secondary chassis about a secondary chassis rotational axis. A pivot connection between the main chassis and the secondary chassis has a pivot axis that is generally parallel with the main chassis rotational axis and the secondary chassis rotational axis.
