摘要： A diagnostic driveline vibration analyzing tool for measuring and characterizing the torsional vibration of a rotating component such as a transmission output shaft in a vehicle driveline. An electronic control unit and sensor cooperate to measure speed fluctuations occurring between the passing of adjacent teeth of a rotating gear. These time measurements are then filtered using an order tracked pass band filter to isolate frequencies of interest the results of which are then used to calculate a total torsional energy level by taking the root mean square of the filtered signal over a predetermined period of time. The total torsional energy level is then compared to a predetermined maximum amplitude and if the total torsional level exceeds this predetermined maximum amplitude then the operator is notified through a display device.

摘要： A diagnostic driveline vibration analyzing tool for measuring and characterizing the torsional vibrations in a vehicle driveline. An electronic control unit and sensor cooperate to measure speed fluctuations occurring between the passing of adjacent teeth of a rotating gear. These time measurements are the basis for displacement, velocity and acceleration calculations which, combined with driveshaft rotational order information, can be used to pinpoint the source of excessive driveline torsional vibrations.

摘要： An intake manifold (18) for an engine (10) includes a Roots-type supercharger (26) having a torsion damping mechanism (54) for reducing audible rattle of timing gears (72,74) which prevents contact of meshed lobes (28a,29a) of the supercharger rotors (28,29). The damping mechanism includes torsion springs (98,100) preloaded against each other. Torsion spring (98) has a low spring rate for attenuating torque fluctions or spikes during non-supercharging, low engine speed modes of operation. Spring (100) has a relatively high spring rate and functions as a shock absorber during engine shut down and during rough engine operation.

摘要： A rotary blower (26) including a pair of shafts (70,56) on which are mounted a pair of rotors (28,29), input to the first shaft (70) being by way of an input pulley (76;108;201). The first shaft (70) has a forward terminal portion (72) extending forwardly of a first timing gear (60) to a location disposed within the input pulley. A torsion damping means is associated with the input pulley (76;108;201) and includes a resilient means (94;124;213) which resists relative rotation between the input pulley and the terminal portion (72) of the first shaft. The torsion damper also includes means (88,90,92;118,122;207,211) for limiting the relative rotation of the input pulley and the first shaft. The disclosed arrangement provides a more compact, less expensive input portion of the blower which eliminates the need for the conventional "third shaft" and its associated bearings.

摘要： An intake manifold (18) for an engine (10) includes a Roots-type supercharger (26) having a torsion damping mechanism (54) for reducing audible gear tooth rattle of timing gears (72,74) which prevent contact of meshed lobes (28c,29a) of the supercharger rotors (28,29). The damping mechanism includes a hard outer shell or band (102) for maintaining the shape of an annular member (100) formed of relatively soft elastomeric material which is fixed for rotation with the gear (74). The member (100) includes three arcuate slots (100c) each defining forward and reverse direction stops (100d,100e) for limiting movement of pins (96) slidably disposed at one end in the slots and fixed at the other end to the input shaft. A torsion spring (98) of low rate resiliently connects the pins to the annular member for reducing the audible gear tooth rattle. A set of three cantilever springs, molded integrally with the annular member, mitigate audible impacts of the reverse stops (100e) by the pins (96).

摘要： A water-cooled remote fan assembly 59, 100 having an extra pulley set mounted between a water drive mechanism 81, 122 and a cooling fan 68, 114 for creating a second overdrive mechanism used to increase the rotational speed of the fan 68, 114 relative to the engine input speed. This provides the pulley-driven engine cooling system with improved cooling capabilities at low engine speeds. By decreasing the radius of one of the pair of auxiliary pulleys 62, 102, 87, 104 mounted to a transfer drive mechanism 66, 116 relative to the radius of a crankshaft pulley 80, 130, the transfer drive mechanism 66, 116 can rotate at a faster rate than the crankshaft pulley 80, 130. One or both of the pair of auxiliary pulleys 102, 104 may be mounted on a shroud 106 of the radiator 108 to provide better fan orientation and higher efficiencies for fan performance.
