A driving system includes: a motor; a power transmission device; a motor controller; an application force controller; and an application force acquiring device. When the motor controller receives a request for generation of power in such a state that the motor generates no power, the motor controller controls to permit and/or prohibit the generation of power of the motor based on the current application force and a necessary application force which is an application force of the power transmission device that is needed to transmit a maximum generation power of the motor in a current rotating state quantity which is a rotating state quantity that the motor is currently having.

An electric axle assembly includes a suspension frame, a pair of drive assemblies coupled to opposite sides of the suspension frame, and a drive module coupled to the suspension frame. The drive module controls operation of the drive assemblies. The electric axle assembly is mounted to a vehicle frame and provides motive force to wheels of the vehicle for propelling the vehicle along a roadway.

An electric drive motor assembly for a wheel includes a wheel hub and an electric motor configured to drive the wheel hub. A drive shaft connects the wheel hub to the electric motor. A pivot member is pivotally connected to the electric motor such that the electric motor is rotatable about the pivot member to accommodate movement of the wheel hub.

The present invention relates to a motor wheel for a vehicle and a vehicle comprising the motor wheel. The motor wheel comprises a wheel, an electric motor, a reduction gear transmitting rotation from the electric motor to the wheel, and a dampening structure connecting the wheel to a vehicle bearing member. The electric motor comprises an electric motor case. The reduction gear comprises a reduction gear case coupled to the electric motor case and rotatably mounted within the wheel hub. The electric motor case is connected to the bearing member of the vehicle and is displaceable relative to the bearing member. The invention improves dynamic properties to the vehicle, reduces vibrations transmitted to the vehicle body, and provides a more comfortable drive.

An exemplary actuator includes a motor, a transmission, and a support structure. The motor includes two torque sources that apply respective input torques to a rotor, which rotates about a rotation axis in response to a net input torque. The torque sources are arranged such that the input torques are additive, resulting in a vector-summated torque output. The torque sources also generate corresponding reactive torques that are applied to the first stator and the second stator. The transmission couples and constrains the first stator and the second stator such that rotational motion of one stator causes counter rotation of the other stator. Thus, the reactive torques are subtractive resulting a differential torque output. In some applications, the differential torque output is used to actuate a suspension of a vehicle. The actuator is also coupled to the vehicle via the support structure, which also reflects a reaction force or torque to actuate other subsystems (e.g., anti-dive, anti-squat).

A suspension system (20) is described for vehicle with a frame, comprising an element (R, 12) propulsive by rolling on the ground; two units (12a, 12b) adapted to impart a torque to the propulsive element that are controllable independently of one another, where the two units are movable relative to the propulsive element independently from one another and rigidly connectable to the frame at one same point (P). By moving one or each unit relative to the propulsive element the distance between the latter and said point is made to vary.

Vehicles are disclosed which have a lower center of gravity than existing all-terrain, amphibious, and unmanned ground vehicles due to the location of propulsion units and other vehicle components inside the wheels of the vehicle. The vehicles can climb over large obstacles yet are also able to corner at high speeds. The vehicles can be configured for direct manual operation or operation by remote control, and can also be configured for a wide variety of missions.

An electric work vehicle includes: a battery pack that is arranged between a left rear wheel arranged outside of a left frame and a right rear wheel arranged outside of a right frame, the front end of the battery pack being located forward of an axle center of a rear wheel unit; a left motor that is arranged above the battery pack, in the periphery of the left rear wheel, receives a supply of power from the battery pack, and transmits rotational power to the left rear wheel; and a right motor that is arranged above the battery pack, in the periphery of the right rear wheel, receives a supply of power from the battery pack, and transmits rotational power to the right rear wheel.

A brake assembly for a vehicle comprising a wheel comprising a hollow section and a rim, the rim comprising a first portion comprising an electrically conductive material and a second portion adjacent to the first portion comprising a plurality of a permanent magnets and a stator comprising at least one electromagnetic coil arranged to be located within the hollow section of the wheel, wherein the stator is moveable between a first position in which the at least one electromagnetic coil is inductively coupled to the first portion of the rim when the wheel is rotating relative to the stator, and a second position in which the at least one electromagnetic coil is inductively coupled to the second portion of the rim.

A vehicle including a vehicle platform having a reference frame, the reference frame arranged along a longitudinal axis. A first vehicle corner module (VCM) is connected to one side of the reference frame and a second VCM is connected to an opposing side of the reference frame. The first and second VCMs are adapted for regulating motion of the vehicle. A sub-frame of at least one of the first VCM and the second VCM is disposed at a splay angle relative to the longitudinal axis.
