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.

Multi-speed planetary transmission

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. The second overrunning clutch is connected between the input shaft and the jackshaft and normally is disengaged when the jackshaft is in operation. The second overrunning clutch, however, provides the advantage of having a means for braking the vehicle through the engine when the vehicle is coasting and power shift clutch is disengaged, since the second overrunning clutch is then engaged and counterrotates to provide the braking means.

Transmission with overrunning clutches

A hydraulic valve for a two-speed power take off selectively operated by a reversible stub shaft providing the proper output drive.

A multiple speed countershaft transmission with a transfer gear drive driven by one of the countershaft gearsets having a gear on the output shaft driving at the output shaft speed to provide an auxiliary power takeoff from the transmission.

Multiple speed transmission with auxiliary transfer drive

A transmission brake with a lubricating and cooling means whereby a portion of the actuating fluid is used to cool the transmission brake and lubricate the brake disks while the transmission brake is operated.

A pivotal support for a vehicle drive line of an articulated vehicle using gimbal rings supporting two universal joints and equally dividing angularity of these two joints and controlling the angularity of a third universal joint of the drive line.

Pivotal support for vehicle drive line having three universal joints

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.

Mechanical differential lock

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.
