The invention relates to an autonomous retarder system for a vehicle including a retarder (10) having a central rotor (11) and two stators (12), one on each side of the rotor (11). The rotor (11) is rigidly coupled to an axle (1). A generator (20, 30, 50) is also included, coupled to the retarder (10), for supplying same with electrical energy. In addition, the generator (20, 30, 50) comprises a stator (22) and a rotor (21, 31, 51) coupled to the retarder.

Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetically induced force that introduces a force threshold that, in effect, provides a threshold to part movement and confers a degree of hysteresis, preventing movement until a sufficiently large energizing force is applied. The effect may be further altered by use of an additional magnetically induced force interaction with at least one further member to urge or slow movement once started and/or to prevent movement once a new position is reached.

A powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.

A method according to an exemplary aspect of the present disclosure includes, among other things, activating hazard lights of an electrified vehicle in response to a high voltage battery disconnect event.

Vehicles with integrated power generation produced by rotation of the wheels are provided. In exemplary implementations, a vehicle includes a frame, a wheel assembly coupled to the frame, and a power generating unit. The wheel assembly includes a wheel defining a wheel axis. The wheel is configured to rotate about the wheel axis during operation of the vehicle. The wheel assembly further includes supporting components fixed about the wheel axis during operation of the vehicle. The power generating unit includes a rotating assembly rotatable with the wheel about the wheel axis, including at least one of a magnet assembly or a coil assembly, and, also includes a stationary assembly mounted to at least one of the supporting components of the wheel assembly or the frame and including the other of the magnet assembly or the coil assembly such that rotation of the wheel rotates the rotating assembly relative to the stationary assembly for generating electrical power.

An electric drive device for a vehicle includes: a rotating machine that is used as a driving force source for traveling of the vehicle; a differential device configured to distribute power transmitted from the rotating machine to right and left driving wheels; and a retarder provided in a power transmission path between the rotating machine and the differential device and configured to generate a braking force. The retarder is either an electromagnetic retarder or a fluid retarder. The rotating machine and the retarder are arranged on opposite sides of an axis of the differential device in a front-rear direction of the vehicle in a plan view seen from above the vehicle, the axis of the differential device being parallel to a width direction of the vehicle.

A transport apparatus includes a transport rail extending along a predetermined path, a transport vehicle configured to be movable along the transport rail to transport a material, and a brake unit mounted on the transport vehicle to be adjacent to the transport rail and configured to apply an eddy current braking force to the transport vehicle.
