摘要： A magneto-rheological damping device comprises a core element for carrying a magnetic flux and a magnetic flux generator positioned adjacent to a portion of the core element and operable to generate a magnetic flux in the core element. A sleeve is positioned over the core element and magnetic flux generator and includes a plurality of protrusions extending generally radially outwardly from a center of the core element. A flux ring surrounds the core element and sleeve and defining a passage between flux ring and core element for the flow of a magneto-rheological fluid. The sleeve protrusions are configured to engage the flux ring and secure the flux ring in a concentric position around the core element and sleeve.

摘要： A brake rotor assembly for a dual brake disc braking system includes an annular ring having a plurality of teeth. The teeth are disposed radially about a central axis of the annular ring, and extend inward toward the central axis. The teeth are for slideably engaging a hub (wheel end) having a plurality of channels. The annular ring includes a plurality of pins extending outwardly from the annular ring. A friction disc is disposed radially about the annular ring, and is in interlocking engagement with the plurality of pins.

摘要： The invention provides a multi-disc brake for a vehicle. A knuckle supports a wheel of a vehicle. A hub is mounted for rotation on the knuckle about a rotation axis. A pair of discs are mounted for rotation with the hub and for sliding movement on the hub along the rotation axis. Each of the discs includes respective inboard and outboard engaging surfaces. Brake pad assemblies are disposed about the discs to engage the engaging surfaces. The brake pad assemblies slide along the rotation axis relative to the hub. A brake fist having a bridge portion extends outboard from the knuckle around the discs and the brake pad assemblies to an outboard wall supporting the outboard brake pad assembly against outboard movement along the rotation axis. An actuator urges the discs and the brake pad assemblies together against the outboard wall to slow rotation of the hub. A first bolt extends along a first bolt axis and a second bolt extends along a second bolt axis spaced from the first bolt axis across the outboard wall for connecting the brake fist to the knuckle. A reinforcing rib extends outwardly from and across the outboard wall to intersect both of the first bolt axis and the second bolt axis in a plane perpendicular to the discs for limiting deflection of the outboard wall.

摘要： A vehicle suspension damper assembly is provided which includes a cup member with a threaded opening formed therein. A piston rod includes a threaded portion, which is engaged in the threaded opening. An electrical connector including a terminal portion is received in an opening formed in the piston rod. The threaded engagement between the piston rod and the cup member is a predetermined length that reduces deflection of the cup member to reduce transfer of load to the terminal portion of the electrical connector.

摘要： An improved magnetorheological fluid damper is provided which effectively provides a smooth transition, without a sharp break in the damper force/velocity curve, between very low damping forces near zero damper velocity to higher damping forces at higher piston velocities while maintaining desirable maximum force levels. The damper includes a piston assembly, including a magnet assembly and a flow gap extending through the piston assembly to permit fluid flow between the chambers. The force/velocity optimization feature includes a groove or passage open to the flow gap, positioned in series with a part of the flow gap in a magnetic circuit generated by the magnet assembly and dimensioned/sized to permit fluid flowing the passage to experience a magnetorheological effect less than a magnetorheological effect experienced by fluid flowing through the flow gap but not through the groove. Preferably, the passage is formed in an inner annular surface of a flux ring positioned around a piston core. The passage may be a single passage or multiple passages and may be formed, for example, by a curvilinear surface, a modified rectangular surface and/or a triangular surface or combinations of surfaces.
