An e-charger includes a shaft supported for rotation about an axis. The e-charger also includes a compressor wheel that is attached to the shaft. The e-charger further includes an electric motor configured to drive the shaft and the compressor wheel in rotation. Also, the e-charger includes a housing that houses the electric motor and at least part of the shaft. Moreover, the e-charger includes a dampening system incorporated in the housing and configured to dampen loads transferring through the housing. The dampening system includes at least one solid-state dampener that is resiliently flexible, and the dampening system includes at least one fluid viscous dampener.

A rotary damper has a displacer device with a damper shaft and displacer components engaging into one another. A rotational movement of the damper shaft can be damped. The displacer device contains a magnetorheological fluid as a working fluid. A magnetic field of a magnetic field source having an electric coil can be controlled by way of an associated control device. An end-side axial gap is formed between the housing and the displacer device. An essential part of the magnetic field of the magnetic field source passes through the axial gap between the housing and the displacer components. The magnetorheological fluid is subjected to the magnetic field in order to adjust a damping of the rotational movement of the damper shaft. The magnetic field also effects a seal of the end-side axial gap.

A damper assembly (100) is configured to dampen motion between a first component and a second component. The damper assembly (100) includes a housing (102) having at least one housing rotation-limiting protuberance (126). A rotor (104) is rotatably coupled to the housing (102). The rotor (104) includes at least one rotor rotation-limiting protuberance (160). The housing rotation-limiting protuberance(s) (126) and the rotor rotation-limiting protuberance(s) (160) cooperate to limit a range of rotation of the rotor (104) relative to the housing (102).

A torque generation apparatus includes a magnetic disc rotatable about a rotation axis, a first yoke, a second yoke, a magnetic viscous fluid placed between the magnetic disc and the first yoke and the second yoke, a coil, and a third yoke. The coil overlaps with the magnetic disc as viewed along the rotation axis. The third yoke constitutes a magnetic path of a magnetic field generated by the coil together with the first yoke and the second yoke. The magnetic disc includes a torque increasing portion at at least one of a surface facing the first yoke and a surface facing the second yoke. The torque increasing portion is provided in an outer circumferential area of the magnetic disc in a radial direction and causes a shearing force to a cluster of the magnetic viscous fluid to become larger than that in the inner circumferential area.

Safe protection equipment for all vehicles will significantly reduce the collision force by elasticity of springs, tubes and stretchable material in that the springs, tubes or cubic bars with stretchable material will be deformed and compressed when the vehicle bumps to obstacle or two vehicles collide with each other. The reduced colliding force will be passed to the chassis by a frame that will move the vehicle forth or back. This equipment can be used on front, rear, side and corner of the vehicle. Combination of springs with stretchable bars can reduce the collision smoothly.

This equipment is attached to the vehicle chassis so the reduced collision force is passed to the vehicle chassis, while the current vehicle can reduce the collision force only by the deformation of the bumper or cover of the body. The remaining colliding force is directly passed to the body of the vehicle and could crash the body of the vehicle or injure the passengers when a heavy collision occurs without the safe protection equipment.

This equipment will protect both vehicles and drivers without changing the current air-bag protection system. It will significantly reduce the damage for serious collision accidents.

A system and method that pertain to a rotating vehicle display unit that can automatically or manually rotate between landscape and portrait orientations, depending on the particular display format or media being shown to the vehicle occupants. The rotating vehicle display unit uses an electro-mechanical rotating and locking mechanism with smart fluid, such as magnetorheological fluid (MR), to facilitate easy and precise rotational movement between different display orientations. The rotating vehicle display unit may be coupled to a corresponding human-machine interface (HMI) that responds to the different display orientations and helps facilitate easy transition from one orientation to another in order to optimize the particular display format or media being shown at that time.

The present invention addresses the problem of providing a one-way clutch and a one-way clutch-equipped rotating damper device with which it is possible to achieve size reduction. A pawl portion of a slide member comprises a withdrawal surface and an engaging surface. When a gear member rotates toward one side, as inner teeth and the withdrawal surface abut each other, the slide member slides in a sliding direction and the pawl portion is withdrawn from the inner teeth, whereby the gear member rotates independently of a rotor shaft. When the gear member rotates toward the other side as the inner teeth and the engaging surface abut each other, the inner teeth and the engaging surface become engaged, whereby the gear member and the rotor shaft rotate integrally.
