US Patent 7927174 Vehicle with controlled motorized movements

A toy vehicle is provided having a wheel base, a chassis, and a cab. The wheel base has pairs of rear wheels. The chassis is attached to the wheel base about a horizontal rotational axis which is capable of raising and lowering the chassis from a first position to a second position. The cab is pivotally attached to the chassis such that the cab is able to remain in a substantially horizontal position when the chassis is moved. The cab further includes a pair of joints that secure arms, which have at the end a wheel. The joint enables the arms to move when the chassis moves. When moving the cab, the vehicle transforms between the first and second positions, where the wheels attached to the arms are able to move with the cab.
