摘要： An in-line transmission provides 26 useful speeds, including 19 forward speeds and 7 reverse speeds. The transmission includes a main planetary having three sets of planetary gears, as well as a separate hi-lo planetary. At least the first and second sets of planetary gears on the main planetary carrier are formed of double gears. Each side of the first set of double gears has its own ring gear which is independently brakable relative to the housing and its own sun gear. Drive from the input shaft to these two sun gears is provided along two main paths, one direct and the other through the hi-lo planetary. One side of the second set of double gears also has an independently brakable ring gear, as well as a sun gear connected to the output shaft. However, the other side of the second set of double gears meshes only with the third set of planetary gears, which preferably are single gears. The third set of planetary gears has its own independently brakable ring gear, and its own sun gear which is both brakable to the housing and clutchable to the main planetary carrier. The hi-lo planetary carrier preferably also uses double gears as planetary gears, with its ring gear meshing with one side of the double gears and its sun gear meshing with the other side. The hi-lo sun gear is selectively brakable to the housing or clutchable to the hi-lo planetary carrier.

摘要： The oil level is controlled between the main gear shift chamber of a transmission and the final reduction gearing/differential chamber by pumping air from the differential chamber into the main gear chamber. The increased air pressure then forces oil back into the differential chamber. The air pump preferably is a simple piston pump driven by a cam on one of the drive shafts on the main transmission chamber. An oil film is provided in the passage connecting the main transmission chamber to allow flow of oil between those chambers, while preventing the flow of air.

摘要： A tractor transmission is synchronized between four different speeds in each of two different high and low ranges and a reverse range. A top shaft coupled to be driven by the tractor engine has four different gears which are concentrically and rotatably spaced along the length thereof in constant mesh with a different one of a second group of four gears formed on the outer surface of a counter shaft. The counter shaft is selectively coupled to the top shaft by either of two pairs of synchronizers concentrically mounted on the top shaft between different pairs of the first four gears. High and low ranges are respectively provided by a first splined collar capable of coupling the counter shaft directly to a differential drive shaft and a second splined collar capable of coupling the differential drive shaft to the fourth gear disposed about the top shaft via a low range driven gear. Upon loss of hydraulic fluid pressure, a planetary gear arrangement coupled between the top shaft and the tractor engine is automatically returned from a direct drive condition to an underdrive condition by mechanical springs within two different clutches associated therewith. Similar safety features are provided in connection with the front wheel drive portion of the transmission.

摘要： An improved self-energized synchronizer for bringing two rotatable members which are aligned about a common axis into synchronization. The synchronizer includes a body member carried on the first rotatable member which in turn engages with an annular shifter collar. Positioned adjacent to the shifter collar is an axially movable annular blocking ring having a frictional surface. Situated on the other side of the blocking ring, opposite the body member, is a drive collar which is rotatably fixed to the second rotatable member. The improvement to the synchronizer includes a frictional disk and a self-energized mechanism for transferring frictional torque between the first and second rotatable members. The self-energized mechanism is positioned for engagement with the blocking ring, while the frictional disk is positioned between the drive collar and the self-energized mechanism. As the operator axially moves the shifter collar, the blocking ring is brought into contact with the self-energized mechanism, and a portion of the mechanism is axially forced into contact with the frictional disk. This contact causes the frictional disk to assist in decreasing the relative rotation between the first and second rotatable members once the self-energized mechanism frictionally engages the blocking ring.
摘要翻译： 一种改进的自励同步器，用于将两个可绕共同轴线对准的可旋转构件带入同步。 同步器包括承载在第一可旋转构件上的主体构件，该主体构件又与环形变速器套环接合。 与移位环相邻定位的是具有摩擦表面的可轴向移动的环形阻挡环。 位于阻挡环的另一侧，与本体构件相对，是可旋转地固定到第二可旋转构件的驱动套环。 对同步器的改进包括摩擦盘和用于在第一和第二可旋转构件之间传递摩擦力矩的自动激励机构。 自动激励机构定位成与阻挡环接合，同时摩擦盘定位在驱动套环和自动激励机构之间。 当操作者轴向地移动换档轴环时，阻挡环与自通电机构接触，并且机构的一部分被轴向地与摩擦盘接触。 一旦自动激励机构摩擦地接合阻挡环，该接触就使摩擦盘有助于减小第一和第二可旋转部件之间的相对旋转。

摘要： A hydraulically operated control arrangement for a transmission includes a spring-loaded pressure regulating valve which slides into a position to cut off an exit chamber for hydraulic fluid from an input chamber for pressurized hydraulic fluid so as to route the incoming hydraulic fluid exclusively to the transmission for various control and lubricating functions when hydraulic fluid pressure in the input chamber falls below a first threshold value. Hydraulic fluid applied to the input chamber continues to feed a first plurality of functions within the transmission via the input chamber and a second plurality of functions in the transmission via an intermediate chamber disposed between the input and exit chambers and in communication with the pressure regulating valve until such time as the hydraulic fluid pressure at the input chamber drops below a second threshold value so as to permit the pressure regulating valve to cut off the intermediate chamber from the input chamber. Loss of hydraulic fluid pressure also causes movement of a power takeoff control lever to the disengaged or off position through the action of a power takeoff control valve which operates a detent arrangement and movement of a planetary control lever into a low position through the action of a high-low control valve.
