A shaft arrangement (34) having a transversely displaceable weight member (42) relative to the shaft arrangement's longitudinal axis (B). The shaft arrangement (34) includes a housing structure (36) within compression structure (44) is arranged. The compression structure (44) extends through the housing structure (36) and connects to the displaceable weight member (42). An elastomeric member (50) is captured between the compression structure (44) and the housing structure (36) so as to resist transverse displacement of the weight member and the connected compression structure (44). The elastomeric member (50) maintains the weight member (42) and connected compression structure (44) in a rotatably balanced position relative to the longitudinal axis (B) for rotation speeds less than a predetermined amount. When the shaft arrangement (34) is rotated faster than such predetermined speed, the weight member (42) and connected compression structure (44) are transversely displaced so as to induce vibration in the shaft arrangement (34).

A hood panel support structure for a secontionalized access opening closure panel of an engine compartment in a hood assembly and the like, including a unique fabricated structure which positions the panel sections, with cross beams having means upon which the panels are secured, and side beams incorporating resilient end mounting means, the structure presenting an aesthetically clean and neat appearance.

A control linkage arrangement for use in a vehicle drive. The drive includes a speed control apparatus having a movable control element for causing the speed of the drive to vary in accordance with the positioning of the control element. Manual control of the operation of the vehicle is effected by an adjustment of a manually operable speed lever which is connected to the movable control element by an improved linkage arrangement. The linkage arrangement includes a ball connector received in a guide channel for effecting rotation of a pivot member connected to the speed control means. Selective positioning of the ball connector in the guide channel effects selective movement of the pivot member in either of opposite directions of rotation and to an extent controlled by the movement of the manually operable speed lever. The ball connector is connected to the speed lever by an extensible device and a range control is provided for varying the extension thereof so as to adjust the disposition of the guide channel relative to a pivot axis of the speed lever to correspondingly vary the effect of the speed lever movement relative to the amount of speed control effected by the device. A lock may be provided for selectively locking the device with the guide channel aligned with the pivot axis of the speed lever so as to preclude operation of the drive notwithstanding a pivoting operation of the speed lever.

A compactor wheel comprises sets of tips each disposed in circumferential alignment therearound with the leading edge of a tip of one set being substantially aligned with the trailing edge of a tip of an adjacent set. Each tip comprises a body portion having a cross-shaped tip portion secured in upstanding relationship thereon to include a first tip portion extending circumferentially and a second tip portion extending transversely relative to the first tip portion and disposed intermediate the ends thereof. A tapered surface and concavity are formed on each lateral side of the first tip portion to dispel material outwardly therefrom during compaction of soils or the like. A plurality of circumferentially aligned blades are positioned on each lateral side of the compactor wheel.

A monitor system for indicating the existence of one or more undesirable operating conditions of an engine-powered vehicle, and including three separate indicator panels. The first panel is energized prior to starting the engine and indicates individual prestart-condition faults, the indicators being disabled after the engine is in operation. The second panel indicates individual operating-condition faults and gives warnings of a different magnitude depending on the criticality of the faults. The third panel is for sevice faults and latches service-fault indications for general presentation to the vehicle operator and individual presentation to service personnel after the vehicle has been shut down.

Vehicle system monitor

A compactor wheel is rotatably mounted on a vehicle and comprises a plurality of pads disposed on the periphery thereof for compacting purposes. A cleaning bar assembly is mounted on the axle housing of the vehicle and comprises an integral U-shaped frame having a plurality of cleaning bars secured thereon to extend inwardly between the pads of the compactor wheel for removing material therefrom. The bars are secured on a pair of legs of the frame which straddle the compactor wheel in parallel relationship relative to the rotational axis thereof. Each of the legs has an adapter means secured on an outboard end thereof adapted to selectively attach an outboard support bar thereon to form a box-like frame enclosing the compactor wheel.

A track-type vehicle comprises a main frame having a pair of laterally spaced track roller frames pivotally mounted on either side thereof. The rearward ends of the track roller frames are pivotally mounted for vertical movements on opposite ends of an axle extending transversely therebetween. The axle is mounted on the main frame by a pair of self-aligning spherical bearing assemblies.

Stress-relieved axle mounting for track-type vehicles

A resiliently supported face seal arrangement with arcuate seal rings that coact with spaced spherical ramps of a bearing mounting to maintain an effective seal and thus a lube chamber and supply for components with relatively large angular misalignment is disclosed.
