Abstract: An embodiment provides a shift inhibitor apparatus for a multiple speed transmission main section. The transmission includes an input shaft and an output shaft The transmission main section has a plurality of selectively engageable ratios. The transmission also has a range section shiftable between a range high ratio and a range low ratio. The shift inhibitor includes an interlock moveable between a locked condition and a released condition, wherein the interlock selectively prevents a gear shift in the transmission main section. The shift inhibitor also includes a range sensor valve. The range sensor valve selectively detects a range shift of the range section. The range sensor valve selectively causes the interlock to be positioned in the released condition upon detection of a completed range shift. The interlock is selectively positioned by a fluid.

Abstract: The transfer tool of this invention includes a handle, a substantially rigid rod extending from the handle, and a peg attachment end.

The peg attachment end is configured to temporarily abut and align with the end of the display peg extending from the display case. Specially designed shipping containers are used to orient the packages in alignment to facilitate transfer of the packages to the display peg with the transfer tool A system and method of using the transfer tool and shipping container of this invention are also disclosed.

Abstract: An embodiment provides a shift inhibitor apparatus. At least a portion of the range actuating assembly is moveable between a range first ratio and a range second ratio. The portion of the range actuating assembly is moveable, at least in part, in response to a fluid pressure. The range chamber is selectively in fluid communication with a vent. The shift inhibitor includes a main section neutral interlock having an interlock chamber. At least a portion of the main section neutral interlock is moveable between a first condition and a second condition. The interlock chamber is selectively in fluid communication with the vent. The range chamber can be exhausted such that the range section is selectively switched from the first ratio to the second ratio. The interlock chamber can be exhausted such that the main section neutral interlock is selectively switched from the first condition to the second condition.

Abstract: A manually shifted, range-type compound transmission (110) is provided with enhanced automatic range shifting. A controller (222) receives input signals indicative of shift selector operation and of vehicle speed (OS) and automatically commands range shifts as a function of both system parameters.

Abstract: A bias mechanism includes a plunger secured within a bore extending in a generally tangential direction through a shift fork hub and intersecting a transverse aperture for mounting the hub on a shift shaft, the plunger having a portion protruding through the bore to selectively contact either the shift shaft or a shifting key or pin during rotation of the shift shaft, and a spring to provide resistance to movement of the plunger within the bore thereby causing rotational resistance to the shift shaft while eliminating axial resistance or drag during translation of the shift shaft. In one embodiment, the plunger contacts a shifting element fixed to the shift shaft, such as a shifting key or pin. In another embodiment, the plunger contacts the shift shaft directly but only during selection of the biased shift yoke for translation to engage a particular gear.

Abstract: A robust control (10) for a pressurized-fluid-operated, three-position shift actuator piston assembly (12). The system requires only a single controlled source of pressurized fluid (44) to provide movement to and retention in a selected one of three axially displaced positions (D, N, OD). A solenoid-controlled valve (42) is controlled by pulse width modulation. Current applied to the solenoid coil is controlled (46), voltage (V) applied to the solenoid coil is sensed and used as a control parameter and/or a relatively light detent (48, 50) biases the assembly to a neutral (N) position to provide a robust control.

Abstract: A control module assembly (200) for mounting as a unit to the housing (116) of a compound transmission (110). The module assembly includes a module housing (202) defining electric (207) and fluid (208) connectors and having an interior containing a position sensor (218) interacting with a transmission shift shaft (188), cavities (212 and 214) defining auxiliary section actuator piston cylinders (204B and 206B), solenoid control valves, a printed circuit board, and various interior electric and fluid conduits.

Abstract: A transmission shifting mechanism (10) and position sensor assembly. The shifting mechanism includes a member (32) of known flux-conducting or flux-insulating properties movable therewith, which will variably extend (42, 44, 46) into an electric coil (36), which is periodically charged and then allowed to discharge. The rate of discharge is variable with the position of the member in the coil and, thus, provides a signal indicative to mechanism condition (H, N, L).

Abstract: An improved single shift shaft shifting mechanism (300) for shifting a mechanical change-gear transmission (10/110) is provided. The shifting mechanism includes a shift shaft (302) which is mounted for axial and rotational movement in a housing (H) for selectively axially moving and/or locking selected or non-selected, respectively, shift forks (302, 304, 306) relative to the housing. To provide an easily shifted, reliable and economical assembly, the shifting projections are defined by a plurality of generally annular shift pins (316, 318, 320) extending radially from bores (322, 324, 326) provided in the shift shaft (308).

Abstract: A manually shifted, range-type compound transmission (110) is provided with enhanced automatic range shifting. A controller (222) receives input signals indicative of shift lever position in the shift pattern (low range/high range) and of vehicle speed (OS) and automatically commands range shifts as a function of both system parameters.

Abstract: An X-control mechanism (200) using an improved and easily installed pivot pin (100) is provided for providing a cylindrical pivot surface (16) about which a pivot arm (8) is able to pivot in response to movement of a control block (6) that is selectively engageable by a primary shaft (3) movable by an operator. The pivoting of arm (8) is operative to slide an x control yoke (14) in an opposite direction along a fixedly secured control shaft (22) for selectively engaging mainshaft gears to a transmission mainshaft 32. Pivot pin (100) is operative to hold pivot arm (8) against the transmission housing (10) between an enlarged head (12) at one end and a snap ring (20) extending radially outwardly from an annular groove (18) adjacent the opposite end.
