In a first aspect, the invention is directed to a multi-speed drive for controlling the speed of a load that is driven from a crankshaft of an engine. The multi-speed drive permits the speed of the load to be adjusted based on one or more parameters, such as vehicle speed, engine RPM, battery charge level (e.g. when the load is an alternator), coolant temperature (e.g. when the load is a cooling fan), engine power demand from the vehicle driver, water level in which the vehicle is driving (e.g. when the load is a cooling fan whose blades could be damaged or could cause damage to other vehicle components if they impact water during use). The speeds provided by the multi-speed drive may include two or more non-zero rotational speeds, or two or more non-zero rotational speeds and a zero speed, or one non-zero rotational speed and a zero speed.

The system of claim 2 , further comprising one or more temperature sensors configured to measure a temperature within the PTO.4. The system of claim 3 , wherein the control system provided a control signal based at least in part on at least one of the measured pressure and the measured temperature.5. The system of claim 4 , further comprising a pump configured to direct lubricant from a suction line at a reservoir of the transmission into the PTO in the mode.6. The system of claim 5 , further comprising:a valve configured to select a first path including the pump for the lubricant for the mode and second path not including the pump when not in the mode.7. The system of wherein the control ...

Torsional vibration dampers are disclosed that include a monolithic body having an axis of rotation, an innermost annular wall defining a bore therethrough for receiving a shaft, and an outer annular wall concentric about the axis of rotation and spaced radially outward relative to the innermost annular wall, an inertia member concentric about the axis of rotation and positioned radially inward relative to the outer annual wall, the inertia member having an inner surface facing the axis of rotation and an outer surface facing the outermost annular wall, a first elastomer member seated against the inner surface of the inertia member, and a second elastomer member seated against the outer surface of the inertia member and in between the inertia member and the outer annular wall. The first and second elastomer members operably couple the inertia member to the monolithic body for rotation therewith. 1. A torsional vibration damper comprising:a monolithic body having an axis of rotation, an innermost annular wall defining a bore therethrough for receiving a shaft, and an outer annular wall concentric about the axis of rotation and spaced radially outward relative to the innermost annular wall;an inertia member concentric about the axis of rotation and positioned radially inward relative to the outer annual wall, the inertia member having an inner surface facing the axis of rotation and an outer surface facing the outermost annular wall;a first elastomer member seated against the inner surface of the inertia member; anda second elastomer member seated against the outer surface of the inertia member and in between the inertia member and the outer annular wall;wherein the first and second elastomer members operably couple the inertia member to the monolithic body for rotation therewith.2. The torsional vibration damper of claim 1 , wherein the outer annular wall is concentric about the innermost annual wall and spaced radially outward therefrom thereby defining an annular ...
