Abstract: A disc brake rotor comprises an internally disposed splined surface defining a circular opening and including one or more axially disposed internal splines that are adapted to be received on external splines of a splined structure of a wheel hub, the surface including a non-continuity such as a cut-away portion of the surface into which independent splines are selectively actuable to align with the internal splines as a part of the surface to allow the rotor to be connected to or released from the hub without using any tools or the like. Preferably, the independent splines are finger actuable, and provide through a workpiece comprising a locking hammer of locking foot.

Abstract: A steering transmission transmits steering forces that must be transmitted from a steering mechanism, such as a steering wheel or handlebars, to a steered mechanism, such as the rudder of a boat or the steered wheel(s) of an off-road vehicle. The steering transmission includes one and preferably both of a multi-ratio speed changer and a torque gate. The multi-ratio speed changer preferably takes the form of one or more planetary gear sets coupling an input shaft of the transmission to a rotary output of the transmission. The speed changer is shifted by manually operating a shifter to switch between two or more distinct speed change ratios, thereby permitting the operator to select the combination of responsiveness and steering effort desired for the prevailing operating conditions. The torque gate preferably takes the form of a release driver, a locking driver, and a wrapped spring disposed between the release driver and the locking driver.

Abstract: A single shear joint is provided which includes a conical ferrule establishing a nesting means of engagement with controlled embedment between a link and a mating component.
