Abstract
Land vehicles and methods of operating land vehicles are disclosed. A land vehicle includes a frame structure, a plurality of wheels, and a brake system. The frame structure includes a front cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the front cage in a longitudinal direction. The plurality of wheels are supported by the frame structure. Each of plurality of wheels is sized to permit direct integration of an electric motor therein.
Claims20
An electric vehicle comprising:
- a frame structure including a front cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the front cage in a longitudinal direction;
- a plurality of wheels supported by the frame structure;
- at least one electric motor supported by the frame structure that is integrated directly into at least one of the plurality of wheels;
- and
- a brake system coupled to each one of the plurality of wheels, wherein each brake system includes
- a disc,
- a first braking device to contact the disc to resist rotation of one of the plurality of wheels that includes a first housing, and
- a second braking device circumferentially spaced from the first braking device about the disc to contact the disc to resist rotation of the one of the plurality of wheels that includes a second housing having a different configuration from the first housing,
- wherein the first housing defines a unitary structure that surrounds an open cavity extending axially all the way through the first housing.
