Filed:

Dec 18, 1987

Appl. No.:

7/134757

Inventors:

David C. Quick - Rockford IL

Assignee:

Sundstrand Corporation - Rockford IL

International Classification:

B64C 1314

US Classification:

244224

Abstract:

An automatic neutral position locking system for a control surface of an aircraft. A hydraulic prime mover is provided for moving the control surface. A locking device is capable of locking the control surface against movement. A ratchet-and-pawl device is operatively associated with a rotary drive train between the prime mover and the control surface for actuating the locking device in response to the control surface reaching a neutral position. The ratchet-and-pawl device normally is maintained in inactive condition when hydraulic pressure exists in the prime mover. A pneumatic piston-and-cylinder device, when under pressure, maintains the ratchet-and-pawl device in normally inactive condition. With a loss of hydraulic pressure, the ratchet-and-pawl device is effective to actuate the locking device in response to the control surface itself reaching the neutral position as the control surface moves under external loads.

Assignee:

Deutz-Allis Corporation - Milwaukee WI

International Classification:

F16H 5702

US Classification:

74767

Abstract:

A single axis multi-speed planetary transmission of the epicyclic type is provided in which a single rotating housing encloses and carries three epicyclic gear sets. Hollow end portions of the rotating housing are carried on a stationary housing by bearings and quill shafts extend from the end portions and are connected to brakes carried on the stationary housing. Two fluid operated clutches are provided within the rotating housing to selectively interconnect certain of the components of the epicyclic gear sets and together with the two brakes provide controls to effect one reverse and five forward speeds. The output shaft is a quill shaft and the input shaft extends through the transmission, and through the output shaft, to provide a power takeoff shaft at the output end of the transmission.

Allis-Chalmers Corporation - Milwaukee WI

International Classification:

F16N 726

US Classification:

184 11R

Abstract:

A differential having lubrication passages including flats on the shafts of the differential spider extending from externally of the differential casing through the differential pinion gears to convey lubrication to the pinion gear and shaft interface for lubrication of the differential. The pinion and ring gears define cone angles directed toward the lubrication groove of the differential.

Inventors:

David C. Quick - New Berlin WI

Assignee:

Allis-Chalmers Corporation - Milwaukee WI

International Classification:

F16H 308

US Classification:

74331

Abstract:

A vehicle transmission having power shift means and an overrunning clutch to selectively provide a multiple speed transmission with shifting of the vehicle transmission while the vehicle is operating. The transmission includes a main drive shaft, a jackshaft and a countershaft with a selective manual gear shift on the countershaft. The main drive is through the countershaft and a plurality of gearsets having clutching means to manually select one of a plurality of speed ratios. The first input speed drives through the first overrunning clutch to the main drive shaft. The jackshaft is selectively engaged through a power shift clutch to provide a second input speed to the main drive shaft. When the jackshaft is in operation, the first overrunning clutch is disengaged and the drive is through the power shift clutch to rotate the main drive shaft at the higher speed. This provides two input speeds to the main drive shaft which are controlled by the operator by selectively engaging or disengaging of the power shift clutch.

US Classification:

747105

Abstract:

A differential having a mechanical differential lock for use in a motor vehicle. The lock includes a plurality of pins carried on a clutch collar for sliding through openings in the differential housing to selectively engage peripheral grooves on one of the side gears of the differential to lock the differential for synchronous rotation of the side gears of the differential.

International Classification:

F04B 1700

US Classification:

4174236

Abstract:

An integrated variable speed compressor drive system for driving a compressor which compresses air from an air source and outputs compressed air. The integrated variable speed compressor drive system includes a hydrostatic transmission coupled to a drive shaft for converting a varying rotational speed of the drive shaft into a first rotational speed. A differential coupled to the hydrostatic transmission and the drive shaft is included in the invention for outputting in response to the varying rotational speed of the drive shaft and the first rotational speed of the hydrostatic transmission, a second rotational speed. The differential is coupled to the compressor and drives the compressor using the second rotational speed. The second rotational speed is related to the first rotational speed output by the hydrostatic transmission. The hydrostatic transmission in response to a control signal supplied thereto varies the first rotational speed to thereby control the second rotational speed which drives the compressor.

International Classification:

F16H 128

US Classification:

74801

Abstract:

An improved support ring (50) is disclosed for supporting a plurality of planetary gear sets (20) which are driven by a centrally disposed input shaft (12) having a sun gear (16) attached thereto in which the planetary gear sets are subject to radially inward loads. The support ring (50) includes an inner ring (52) and an outer ring (57). The inner ring (52) has a bore (54) which is disposed around the input shaft (12) and an outside surface (56) and the outer ring (57) has a bore (58) with a diameter greater than the diameter of the outside surface of the inner ring. The outside surface (60) of the outer ring rotatably supports the planetary gear sets (20). Preferably, the outer ring (57) has a spring rate which is less than the inner ring (52) to readily permit absorption of radial loads when the outer ring does not contact the inner ring. A retaining ring (62) may be provided to maintain a fixed axial relationship between the inner (52) and outer rings (57).
