  • Patent number: 8336425
    Abstract: A cast metal connecting rod of the type used in a reciprocating piston engine has a beam section between two end sections. The beam section and the end sections are integral with one another and are at least partially made of a cast metal material. At least the beam section of the connecting rod includes an insert made of a sintered powder metal material. The insert is at least partially encapsulated by the cast metal material of the connecting rod. The insert reinforces the connecting rod and can help match characteristics of surrounding or mating parts of the engine that are made of materials more similar to the material of the insert than the cast metal of the connecting rod. The cast metal material, for example aluminum alloy, of the connecting rod can also provide localized regions of high machinability where needed.

  • Patent number: 8336413
    Abstract: A power steering apparatus includes a housing defining a chamber. A rack is disposed within the chamber and is moveable along a longitudinal axis. A pinion extends into the chamber for meshing engagement with the rack. A bearing supports the rack relative to the housing and is moveable relative to the housing to re-position the rack relative to the pinion. An adjustment mechanism continuously biases the bearing in response to loosening of the meshing engagement to re-position the rack. A dampener resists the movement of the bearing to slow the re-positioning of the bearing. Preferably, the dampener includes a plastic fluid having a very high viscosity. The plastic fluid is disposed between adjacent moving parts to resist the relative movement between the bearing and the housing.

  • Patent number: 8276478
    Abstract: A pedal bracket (3) affixed to a dash panel (1) pivotably supports a pedal unit (2) via a first pivot shaft (13) and a pivotable lever (5) via a second pivot shaft (17). A shaft retainer (51) prevents a downward displacement of the first pivot shaft (17) under normal conditions, whereas the pivotable lever (5) goes into contact with a side member (33) of a vehicle body and pivots on the second pivot shaft (17) in a specific direction in the event of a vehicle collision, thereby thrusting and displacing the first pivot shaft (13) downward and disengaging the pedal unit (2) from the pedal bracket (3). At this time, the shaft retainer (51) draws back from underneath the first pivot shaft (13), for instance, as a result of pivoting of the pivotable lever (5) and goes into a nonrestrictive state in which the shaft retainer (51) allows a displacement of the first pivot shaft (13).

  • Patent number: 8220362
    Abstract: A cam and cam follower apparatus translates linear cam bar movement to perpendicular valve stem actuation in an injection molding system. The cam bars reciprocate up and down on linear bearing rails such that an actuation plate, fitted with a plurality of valve stems, is cycled normal to the direction of the cam bar movement via cam followers traveling within cam slots in the cam bars. The cam slots in the cam bars are profiled such that the cam followers affect the speed and force at which the valve stems travel while at the same time reducing frictional effects and their associated power requirement. The cam followers of the valve stem actuation plate travel in cam slots in the cam bars from a valve stem forward position, to a valve stem retracted position and ultimately, the entire actuation plate may be removed from the cam bars for maintenance via open ended slots in the cam bars.
