A drive unit for a skid steered vehicle includes a controlled differential positioned between two shafts. The end of each shaft forms an output of the drive unit connected directly to the differential outputs via the shafts. A steer motor is in driveable communication with the differential, and an electric propulsion motor is in driveable communication with the shaft outputs. A gear reduction unit, and optional gear change unit, is positioned between the differential and the electric propulsion motor. The electric propulsion motor, the gear reduction unit and optional gear change unit are connected in a parallel connection with an output of the differential to the shaft outputs. The optional gear change unit includes an epicyclic gear reduction unit having an input and an output which provides drive input from the gear change unit to the shaft. A gear change set has a master gear that receives drive output from the electric propulsion motor, and slave gears which are driven by the master gear via one or more gear chains. A dog clutch slideably engages the input of the gear reduction unit and selectively engages with the master gear or slave gears so that the selected position of the dog clutch determines which gear is engaged.

An electrified vehicle axle includes a first wheel assembly having a first electric machine configured to power a first wheel and a second wheel assembly having a second electric machine configured to power a second wheel.

At least one clutch selectively couples at least one of the electric machines to the axle shaft.

A brake apparatus for a vehicle may include: a stator unit fixed to an inside of a wheel of the vehicle, a rotor unit disposed to face the stator unit and rotated by electromagnetic interaction with the stator unit, a disc unit connected to the rotor unit and rotated together with the rotor unit, a pair of caliper units disposed on both sides of the disc unit and configured to generate a braking force by contacting with the disc unit as hydraulic pressure is applied, and a transfer unit connected to the pair of caliper units, and configured to transfer hydraulic pressure applied to one of the pair of caliper units to a remaining one of the pair of caliper units.

A wheel hub drive system includes a drive motor with a drive shaft, an input planetary gear set (PGS), an output PGS and an intermediate PGS. Each PGS includes a sun gear, a planet carrier and planet gears provided upon the planet carrier. The drive shaft is rotationally fixed with the sun gear of the input PGS. The planet carrier of the input PGS is rotationally fixed with the sun gear of the intermediate PGS, and the planet carrier of the intermediate PGS is rotationally fixed with the sun gear of the output PGS. The planet carrier of the output PGS is adapted to be rotationally fixed with a rim of a wheel. The output PGS is provided axially in-between the input PGS and the intermediate PGS.

A modular electric wheel assembly includes integral/in-built acceleration and braking componentry and/or steering and suspension componentry allowing for the modular application thereof. Each modular wheel assembly may receive drive control data from various sensors (such as accelerator and brake pedal position sensors, steering column rotational offset sensors and the like), vehicle control systems or the like so as to be able to independently drive, brake, steer and/or provide active suspension for the vehicle. The wheel assemblies may communicate with each other across a wheel assembly vehicular network, wherein a master wheel assembly may receive drive control data and control the slave wheel assemblies accordingly. The modular wheel assemblies may further communicate with each other to receive various sensor data, including rotational speed sensor data so as to be able to detect loss of traction events and the like so as to substantially autonomously take remedial traction control action.

An electric motor including a stator between a first and second rotor. The stator and the rotors are mounted to non-rotating shaft. The stator includes a plurality of windings and the first and second rotors include a plurality of magnets on a side thereof facing the stator. An opening internal to the electric motor is to provide cables and cooling to the stator. A hub is secured to opposite side of the first rotor as the plurality of magnets and rotates with rotation of the rotors. The hub includes a plurality of bolts extending therefrom to mount a rim thereto by placing the bolts through aligned holes in the rim. The motor is mounted in each wheel assembly of an electric automobile so that each wheel thereof is controlled by its own motor.

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.

A hydraulic motor for vehicle wheel includes a hydrodynamic element, a reaction element, an oil distributor rotating as one with the reaction element, and a brake mounted between the two elements to oppose the rotational movement. The hydrodynamic element has a flange that surrounds the oil distributor. On its radially exterior face, it has means for rotationally coupling with the rotary discs of the brake. The brake is thus positioned around the distributor.

A gearing arrangement that offers a new way to operate an electric motor at a favorable operating point is provided. To this end there is proposed a gearing arrangement (1) for an electric motor (6) of a vehicle (2), including an input interface (5) for coupling to the electric motor (6) and including an output interface (7), such that a drive torque path runs between the input interface (5) and the output interface (7); including a first transmission gearing stage (10) with a first transmission ratio (i1), such that the drive torque path in a first operating state of the gear arrangement (1) runs via the first transmission gearing stage (10); and including a second transmission gearing stage (11), such that the drive torque path in a second operating state of the gear arrangement (1) runs via the second transmission gearing stage (11), the second transmission gearing stage (11) having a continuously variable transmission ratio (i1 . . . i2).
