464097000 | Element is a torsion bar having a longitudinal axis coincident with the rotational axis | 10 |
20100279780 | DRIVE FOR TRANSIT DOOR - A multi-part drive shaft for a transit vehicle door comprises an upper drive shaft connected to a door operating mechanism and having a door panel operating arm extending therefrom, a lower drive shaft journaled for rotation, a door panel operating arm extending therefrom and a flexible drive shaft secured at one end to the upper drive shaft and at the other end to the lower drive shaft. Rotation of the upper drive shaft will transfer torque to the lower drive shaft at the same angular speed. | 11-04-2010 |
20130040741 | JOINT ARRANGEMENT FOR USE IN A MOTOR VEHICLE - A joint arrangement for use in a motor vehicle includes a joint housing, an input shaft securely connected to the joint housing, a jointed shaft disposed in the joint housing for conjoint rotation by a tripod bearing assembly, and a flexurally elastic connecting arrangement connected to the input shaft by a fixing region. The flexurally elastic connecting arrangement provides at least one defined bending region. | 02-14-2013 |
20140274423 | VEHICLE STEERING SYSTEM TORSION BAR - A vehicle steering assembly comprising an input member, an output member, and a torsion bar coupling the input member to the output member. The torsion bar includes primary and secondary load structures, and the secondary load structure is inoperative below a transition torque. The primary load structure includes a primary torque member that constantly couples the input member to the output member throughout an operative range of the steering assembly. The secondary load structure includes first and second torque members that are separated by a gap when the assembly encounters a torque below the transition torque and that contact each other when the assembly encounters a torque above the transition torque. The first torque member can comprise a tubular structure surrounding the primary torque member. The tubular structure includes an opening defining a circumferentially-exposed surface, and the second torque member includes a radially-extending arm positioned in the opening. | 09-18-2014 |
20160032983 | DRIVESHAFT ASSEMBLY - A drive shaft assembly is formed from two concentrically arranged driveshafts fastened together near to one end of the driveshaft assembly so as to prevent relative rotation therebetween and connectable together near to an opposite end via a torque sensitive drivable connection. The torsional stiffness of the driveshaft assembly is primarily dependent upon whether one or both driveshafts are arranged to transmit torque. The drivable connection may be a mechanical lost motion connection which is operable to either connect the two driveshafts together or not based upon the magnitude of torque applied to the driveshaft assembly. Therefore, the driveshaft assembly provides more than one torsional stiffness allowing it to be better optimized to meet differing operational requirements. | 02-04-2016 |
20160097420 | DRIVESHAFT WITH TWO-STAGE STIFFNESS - A two-stage stiffness driveshaft includes a hollow cylinder defined by a longitudinal axis, a first end, a distal second end, and a hollow cylinder stiffness. The driveshaft also includes an inner shaft extending through the hollow cylinder along the longitudinal axis and defined by a first end, a distal second end, and an inner shaft stiffness. The first end of the inner shaft is engaged with the first end of the hollow cylinder via a rotational clearance fit. The second end of the inner shaft is rotationally fixed to the second end of the hollow cylinder such that the first end of the inner shaft can twist to a predetermined angle with respect to the second end of the inner shaft. The inner shaft stiffness defines a first-stage stiffness of the driveshaft, and the inner shaft stiffness and the hollow cylinder stiffness together define a second-stage stiffness of the driveshaft. | 04-07-2016 |
20160123377 | TORQUE TRANSMITTING SHAFT - A torque transmitting shaft includes a first member and a second member. The first member extends along an axis and has an inner surface extending between a first end and a second end. The inner surface defines a plurality of first engagement elements disposed proximate the first end. The second member extends along the second axis and has a first end portion and an intermediate portion extending from the first end portion. An end of the intermediate portion is fixedly attached to the second end. The first end portion has a first spline portion and each member of the first spline portion is received within corresponding engagement elements of the plurality of first engagement elements. | 05-05-2016 |
20160146245 | TUNABLE TORQUE TRANSMITTING SHAFT - A torque transmitting shaft includes a first member and a second member. The first member has an inner surface that defines a plurality of engagement elements. The second member has a first end portion, a second end portion, and an intermediate portion. The first end portion of the second member defines a splined portion. Each member of the splined portion is received within corresponding engagement elements of the plurality of engagement elements. Each member of the splined portion includes a first protrusion that engages the inner surface of the first member. | 05-26-2016 |
