Abstract:
A sphere drive line retarder is presented that is mounted to a drive shaft from an engine. The sphere drive line retarder comprises a sphere rotor mounted to the drive shaft and housed within a retarder housing. The sphere drive line retarded has a piston assembly comprising at least one piston, a brake shoe mounted to each piston, and hemispherical friction material mounted to the brake shoe. The hemispherical friction material is located between the sphere rotor and the brake shoe. Each piston is housed within a piston housing that is hydraulically isolated from the retarder housing. The retarder housing contains hydraulic fluid to cool the sphere rotor.
Abstract:
A brake (44, 144, 244) is provided. The brake (44, 144, 244) may include a rotor (46, 146, 246) having a plurality of magnets (52, 152, 252) and a plurality of ferromagnetic poles (54, 154, 254) radially disposed thereabout, and a stator (48, 148, 248, 348, 448) having a plurality of shunts (58, 158, 258, 358, 458) and a plurality of teeth (60, 160, 260, 360, 460) radially disposed thereabout. At least one of the plurality of shunts (58, 158, 258, 358, 458) and the plurality of teeth (60, 160, 260, 360, 460) may be configured to selectively move between an engagement state and a free engagement state. The teeth (60, 160, 260, 360, 460) may be configured to generate magnetic flux with the ferromagnetic poles (54, 154, 254) so as to generate a braking torque during the engagement state. The shunts (58, 158, 258, 358, 458) may be configured to redirect the magnetic flux therethrough and reduce the braking torque between the teeth (60, 160, 260, 360, 460) and the ferromagnetic poles (54, 154, 254) during the free engagement state.
Abstract:
Self-Braking Ball Clutch (SBBC) and Feeding Drive. SBBC is a device that allows to move/feed a rod ONLY in one direction. This one directional feed is made possible by the balls housed between the corneal base surface of the housing, that has a reverse angle smaller than the braking angle, and a rod surface. With this design, the bails do not restrict the rod movement in the angle opening direction. However, if the rod were to be moved In the opposite direction, the balls would be wedged between the conical base surface of the housing and the rod surface, thus completely restricting the rod movement. The principle of the self-braking lock is the basic idea for the bail feeding type designs, ball catchers in safety systems, lifting and transportation mechanisms, as well as for easy length adjustable link.
Abstract:
Die Erfindung betrifft einen schaltbaren Freilauf (10) zur Weiterbildung einer elektromechanischen Fahrzeugbremse (Betriebsbremse) zu einer Feststellbremse (Parkbremse). Die Erfindung schlägt einen Klemmfreilauf (10) mit Klemmrollen (16) vor, die in einem Klemmrollenkäflg (22) aufgenommen und durch Schwenken des Klemmrollenkäfigs (22) in eine Ab- und eine Einschaltstellung bringbar sind. Der Klemmrollenkäfig (22) weist einen radial abstehenden Hebel (30) auf, an dem ein Aktuator (40) in tangentialer Richtungangreift. Auf diese Weise ist ein in axialer Richtung kurz bauender Freilauf (10) möglich.
Abstract:
A brake sphere apparatus of a spherical braking system is mounted on the axle or drive shaft of a vehicle. A brake sphere is connected to a wheel hub and rotates simultaneously together with the wheel hub. A housing contains the brake sphere, two brake pads on opposing sides of the brake sphere, and two hydraulic shafts respectively driving the two brake pads. Two hydraulic lines are connected to the two hydraulic shafts through the housing, the two hydraulic shafts press the two brake pads against the brake sphere when pressure is applied through the two hydraulic lines. Cooling is provided to cool the brake sphere when torque is applied to said brake sphere to decrease simultaneous rotation of the brake sphere and wheel hub.
