Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F16H 59/68

US Classification:

74335, 74745

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.

International Classification:

F16H 59/00

US Classification:

74335, 74331, 74339, 74329

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.

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F16H 5904
F16H 6342
G01B 700

US Classification:

74335

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).

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F16H 5900

US Classification:

74335

Abstract:

A fluid pressure actuated auxiliary transmission section (14) shift control system (3230/270)/method is provided which includes a control member (246) to prevent auxiliary section synchronized clutch (92, 128) damage if the main transmission section (12) is engaged during an auxiliary section shift. A range synchronizer protection valve (246) is effective to exhaust at least the high speed ratio chamber (224) of the piston actuator (220) whenever a main section engaged condition is sensed.

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F16H 5908

US Classification:

74745

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.

US Classification:

74339

Abstract:

A semi-automatic mechanical change gear transmission system (11) including a manually operated non-synchronized mechanical change gear transmission (12), a plurality of two-position sensors (278, 280, 282, 284, 286 and 290) cooperating with sensor ramps (146, 148, 150, 152, 154 and 156) manually provided on the operated shift rails (104, 106 and 108) for sensing manual selection of engagement or disengagement of a particular ratio gear, speed sensors (48 and 50) for sensing the rotational speed of the jaw clutch elements associated with a particular selected ratio gear, a power synchronizer assembly (10) and a inhibit mechanism (304) associated with a standard interlock/neutral sensing assembly (254) to resiliently resist axial movement of the shift rails (104, 106 and 108) from the axially nondisplaced positions thereof in the absence of synchronous rotation of the jaw clutch members associated with a particular selected ratio gear.

International Classification:

F16H 5910

US Classification:

74473R

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.
