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;
- a plurality of wheels supported by the frame structure;
- at least one electric motor supported by the frame structure;
- and
- a brake system coupled to each one of the plurality of wheels,
- wherein:
- each brake system includes a disc and a first braking device to contact the disc to resist rotation of one of the plurality of wheels that includes a first housing,
- the first housing defines a unitary structure that surrounds an open cavity extending axially all the way through the first housing, and
- the open cavity is radially offset from a central rotational axis of the disc.

An electric vehicle comprising:
- a frame structure;
- a plurality of wheels supported by the frame structure;
- at least one electric motor supported by the frame structure;
- 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, and a second braking device to contact the disc to resist rotation of one of the plurality of wheels;
- the disc includes an outer annular surface that extends circumferentially to at least partially define an outer diameter of the disc;
- the first braking device is configured to contact an outer face of the disc without enclosing the outer annular surface, and
- the second braking device is configured to contact an outer face of the disc without enclosing the outer annular surface.
