US Patent:

46401520, Feb 3, 1987

Filed:

May 16, 1985

Appl. No.:

6/734545

Inventors:

David C. Quick - New Berlin WI
Stephen J. McCormick - Shorewood WI
Gerardus M. Ballendux - Waukesha WI

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.

Assignee:

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.
