A motor drive device includes: a trailing arm that extends in a vehicle front-rear direction and includes a vehicle body-side attachment portion and wheel-side support portion, the vehicle body-side attachment portion formed on a forward portion side of the trailing arm and coupled to a vehicle body via a rubber bush, the wheel-side support portion formed on a rear side of the trailing arm and supporting a rear wheel; and a motor that is supported by the trailing arm and drives the rear wheel. The motor and the rubber bush are disposed in such a way that motor and the rubber bush are seen as being substantially aligned in a vehicle up-down direction when viewed in a vehicle width direction.

A vehicle height adjusting device includes a vehicle height adjusting unit, a prediction unit, and a vehicle height control unit. The vehicle height adjusting unit adjusts a vehicle height to one of a first state and a second state. In the first state, the vehicle height is set to a predetermined height, and in the second state, the vehicle height is set lower than the first state. The prediction unit predicts whether a drive battery (lower portion) of a vehicle interferes with a road surface in the second state. The vehicle height control unit controls the vehicle height adjusting unit to set the vehicle height to one of the first state and the second state. When the prediction unit predicts an interference between the drive battery of the vehicle and the road surface, the vehicle height adjusting unit restricts a transition from the first state to the second state.

The present disclosure discusses a transportation vehicle configured for transforming between a drive mode and a flight mode. The vehicle includes a chassis with a body coupled thereto and a plurality of fenders coupled to the body. Each of the fenders includes a rim comprising spokes and a tire configured to rotate during drive mode and a suspension configured to pivot the plurality of fenders from a substantially vertical orientation during drive mode to a substantially horizontal orientation during flight mode. Each of the fender also includes a propulsion mechanism configured to rotate independently of the rim to generate lift during flight mode and a motor configured to independently provide rotational force to the tire built into the rim during drive mode and rotational force to the propulsion mechanism during flight mode.

The present disclosure relates to autonomous driving vehicles and methods for improving stability and occupant comfort of the same. The vehicle includes: a frame member; a cabin, movable with respect to and independent from the frame member; wheels; at least one suspension between the wheels and frame member; actuation device configured to control at least the orientation of the cabin with respect to the frame member; a perception module comprising perception sensors and algorithm configured to at least identify road boundaries and obstacles in the vicinity of the vehicle; and a planning module configured to plan the motions of the steering means using information from at least the perception module.

A subframe assembly for a vehicle and a method for manufacturing the same is disclosed. The subframe assembly includes a crossmember, a straight arm, and a side bracket. The crossmember includes an end bracket disposed at an end thereof. The straight arm is received into and metallurgically bonded to the end bracket of the crossmember. The side bracket includes a base, and a rear bracket arm. The base is metallurgically bonded to a side of the straight arm adjacent to the end of the crossmember. The rear bracket arm extends from an end of the base and defines a hole adapted to receive a screw or pin for connecting a control arm of a wheel suspension to the subframe assembly. The rear bracket arm is at least partially received into and metallurgically bonded to the end bracket of the crossmember.

A suspension and traction system (MC) is described for vehicles equipped with a frame and a propulsive element (R.), which by rolling on the ground (T) is adapted to move the vehicle relative to the ground (T).

A rotary electric motor (12) operates two rotors (14, 16) independently controllable from one another to supply two epicycloidal mechanisms (20, 30) whose outer ring gears (28, 38) are independently movable to rotate about the respective solar gear (24, 34) and rigidly connected substantially to a same point (P) of the frame.

A rear axle of a two-track vehicle includes a plurality of wheel-control links with at least one spring link for supporting a bearing spring on a vehicle body of the vehicle, which wheel-control links connect a rear wheel of the vehicle to a rear axle carrier. The rear axle carrier includes at least two longitudinal members oriented at least approximately in the longitudinal direction of the vehicle and at least one crossmember oriented at least approximately in the transverse direction of the vehicle. The rear axle carrier is attached to the vehicle body via two bearing points on each side of the vehicle, as viewed with respect to the longitudinal center axis of the vehicle. The spring link and at least one of the wheel-control links are attached to the longitudinal member. The attachment of the spring link to one longitudinal member in each case is arranged, as viewed in the travel direction of the vehicle, upstream of the center of the distance between the bearing points arranged on a common side of the vehicle.

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 control system for controlling motions of a vehicle having wheels is provided. The control system includes suspension units configured to support the wheels respectively driven by motors controlled by throttles, a set of sensors configured to detect the motions of the vehicle, wherein the motions are represented by lift, pitch, and roll values of the vehicle, an allocation module configured, in connected with the sensors, to generate and transmit allocated throttle signals to the throttles to minimize the motion by solving an optimization problem related to the motion, and a motor control unit configured to drive each of the motors via the throttles according to the allocated throttle signals.

An electric vehicle includes a chassis, a rigid axle housing, and a suspension system control arm coupling the rigid axle housing to the chassis. The electric vehicle also includes first and second electric motors, each having a rotator and a stator. The stator of the first and second electric motors are rigidly fixed to the rigid axle housing. The electric vehicle also includes a coolant supply system coupled to a radiator and the rigid axle housing to supply coolant from the radiator to a coolant inlet of the rigid axle housing and to supply used coolant from a coolant outlet of the rigid axle housing to the radiator. A first mounting bracket is fixed to the chassis and the coolant supply system. A second mounting bracket is fixed to the rigid axle housing and the coolant supply system, and a third mounting bracket is fixed to the control arm and the coolant supply system.
