Chassis assembly for an electrical powered vehicle
First Claim
1. A chassis assembly for an electrical vehicle comprising:
- a main chassis, the main chassis having a front end and a rear end;
at least one main chassis wheel rotationally coupled to the main chassis about a main chassis rotational axis;
a secondary chassis pivotally coupled to the main chassis, the secondary chassis configured and arranged to hold batteries that supply energy to an electric motor coupled to the main chassis;
at least one secondary chassis wheel rotationally coupled to the secondary chassis about a secondary chassis rotational axis;
the pivot connection between the main chassis and the secondary chassis having a pivot axis that is generally parallel with the main chassis rotational axis and the secondary chassis rotational axis;
a connection base coupled to the rear end of the main chassis, the connection base further including an upper portion with opposed extending rods;
at least one elongated connection member configured and arranged to pivotally couple the connection base of the main chassis to the secondary chassis; and
the at least one elongated connection member further including a pair of elongated connection members, each elongated connection member having a first end and a second end, the first end of each elongated connection member including an aperture, an associated extending rod of the upper portion of the connection base being received in an associated aperture in the first end of an associated elongated member.

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.
