摘要： A steering shaft assembly includes a male shaft having a plurality of splines formed thereon, each of the splines terminating at a spline end, wherein each of the spline ends form an angle of about 90 degrees relative to a longitudinal direction of the splines. The steering shaft assembly also includes a female shaft including a plurality of stakes located proximate an end of the female shaft, the stakes retaining the male shaft at an interface between the stakes and the spline ends.

摘要： A low surface-roughness part is formed at a first tapered part, and, as a result, the roughness of an opening-edge of a groove part of an internal spline part that opens at the first tapered part is reduced, and surface pressure applied by the opening edge to a tooth of an external spline part can be reduced. As a result, the opening edge of the groove part of the internal spline part can be kept from digging into the tooth, and variation, between products, in the insertion load of a second shaft part can be suppressed.

摘要： A steering shaft for a motor vehicle may have an inner shaft, an outer shaft, and a profiled sleeve that is fixed on the inner shaft such that the inner shaft is movable together with the profiled sleeve in an axial direction relative to the outer shaft. The inner shaft and the outer shaft may be coupled in a torque-transmitting manner with the profiled sleeve connected therebetween. The profiled sleeve may comprise an aperture into which a projection on an outer face of the inner shaft engages in a manner that secures the profiled sleeve in position on the inner shaft at least in the axial direction.

摘要： A cardan shaft slip distance change detection system for determining the amount of length change of the cardan shaft, including a moveable element and a stationary element associated with a telescopic approach to compensate for the change of distance caused by the vehicle's axle movements. At least two conductive elements are configured as one of them connected to a fixed point, another to the moveable element. A power element is provided to supply power to at least one of the conductive elements. A detection unit measures the electrical value change provided by the electrical interaction between the conductive elements and correlating it with the distance between the conductive elements.

摘要： A composite vehicle driveshaft is provided with a crash collapse system that allows for a controlled longitudinal collapse of the driveshaft by facilitating telescopic movement of various components with respect to each other during a crash event. The crash collapse system may include a collapsible joint with a sleeve that is concentrically bonded in an end of a composite tube and a stub end assembly that is spline-engaged and interference fit within the sleeve, such as by way of a press-fit and/or a thermal shrink-fit procedure. This relationship may rotationally lock and axially fix the stub end assembly to the sleeve unless, during a crash event, the composite vehicle driveshaft experiences a compression or push-type force that exceeds a minimum breakaway or collapse force value that longitudinally and telescopically collapses the composite vehicle driveshaft.

摘要： A steering shaft having an outer shaft and an inner shaft accommodated therein in a torque-locking, axially displaceable manner and an axial inner stop which projects radially outwards from an outer face of the inner shaft. When the inner shaft is pulled out of the outer shaft, the axial inner stop strikes against an axial outer stop projecting radially inwards from an inner face of the outer shaft, wherein the axial displacement of the inner shaft is limited in the pull-out direction. With regard to simple production of the outer stops with the least possible deformation of the entire cross section of the outer shaft, the outer stop is introduced by at least one forming process into an end portion of the outer shaft, wherein the axis of the direction of introduction in each case forms an angle of more than 20° with the radial direction of the outer shaft.

摘要： A system includes a pair of gearboxes each having an output shaft. A first adapter is connected to the output shaft of the first gearbox, and a second adapter is connected to the output shaft of the second gearbox. A first drive shaft is connected to the first adapter, and a second drive shaft is connected to the second adapter. Each drive shaft may articulate with respect to an axis defined by its associated output shaft through an angle of at least twenty degrees.

摘要： A bailing apparatus may include a multi-component bolster assemblies that may ease installation and removal, reduce wear and tear and maintenance, and/or improve baling efficiency by reducing material waste, imperfections, and/or contamination. The bolster assemblies may include a plurality of coupling portions that engage a hydraulic rod and may enable the bolster assembly to self-center within a press chamber during normal baling operations. The bolster assemblies also may include an island portion that may be attached to the coupling portions and to a bolster cap, and the latter may be attached using retainer bolts having substantially planar heads that may define lips that run about frustums. The bolts may substantially planar head may reduce irregularities in the bale and the lips may prevent material seepage into the bolster assemblies.

摘要： To provide a rear wheel braking device for a motorcycle that can reduce an unsprung mass and the number of pieces of components on the rear wheel side of a shaft drive type motorcycle. In a rear wheel braking device for a motorcycle transmitting a drive force of a power unit of a motorcycle to a rear wheel through a drive shaft that extends in a vehicle longitudinal direction, the drive shaft includes a propeller shaft that is connected to a rear end of an output shaft through a universal joint, the output shaft protruding to the vehicle body rear side from a case member of the power unit. A brake disk is attached to the output shaft, the brake disk being braked by a rear wheel brake caliper. The rear wheel brake caliper is fixed to a bracket that is arranged in the case member, and is disposed on the vehicle body upper side of the brake disk.

摘要： Sealing arrangement for length compensation of an articulated shaft, where the sealing arrangement has a first shaft element which has a seat section, and a sealing sleeve with a fastening section. A circumferential groove is arranged on the seat section for fixing the sealing sleeve on the first shaft element. The sealing sleeve engages into the circumferential groove. The sealing sleeve, by way of the fastening section, is axially pushed onto the seat section in the direction of a longitudinal axis. The fastening section has at least one latching projection which projects radially inward and which engages in a latching manner into the circumferential groove when the sealing sleeve is in the fully pushed-on state. The seat section has a circumferential sealing face against which the fastening section of the sealing sleeve bears in an elastically tensioned manner in the fully pushed-on state.
