    摘要： An improved, blocked, change gear transmission utilizing at least one improved resilient jaw clutch assembly to selectively engage a selected gear to a shaft is provided. The improved jaw clutch assembly comprises two axially engageable jaw clutch members and a blocker mechanism to prevent engagement of the jaw clutch members until the jaw clutch members are rotating at a substantially synchronous speed. Preferably, one of the jaw clutch members carries axially and radially outwardly extending external clutch teeth designed for selective interengagement with axially and radially inwardly extending internal jaw clutch teeth carried by the other jaw clutch member. The improvement comprises providing a back-lash between the interengageable clutch teeth which is substantially greater than the back-lash normally utilized with similar clutch assemblies, said increased back-lash being in the range of five to fifteen times greater than normal back-lash and preferably about ten times greater than normal back-lash.

    摘要： An improved shiftable change speed transmission is provided. The improved transmission is preferably provided with at least one countershaft having countershaft gears thereon disposed in meshing engagement with main shaft gears encircling the transmission main shaft. Gears are selectively axially movable relative to the associated shaft by conventional means for effecting shifting of the transmission. The axially movable gears cooperate with clutch rings which surround and are supported on and for rotation with the associated shaft by splines, preferably the clutch rings also are axially movable relative to the associated shaft and are resiliently urged in a direction toward the respective gear with which same cooperates, whereby shifting of the axially movable gear toward its respective clutch ring causes resilient axial movement of the latter until synchronization is achieved to permit the clutch ring to move axially in response to said resilient urging and engage the main shaft gear. The improvement comprises providing spline teeth on the clutch ring or the associated shaft which are of a substantially constantly varying thickness and are arranged such that, when the clutch rings are in the non-axially displaced position, the circumferential spacing betwen cooperating clutch ring and shaft spline teeth is smaller at the axial end of the clutch ring closest to the gear with which it is associated than at the other end of the clutch ring.

    摘要： A compound change gear semi-blocked transmission (10) of the splitter type is provided. The transmission comprises a multi-speed main section (12) connected in series with an multi-speed auxiliary section (14). The main section utilizes manually engaged, non-blocked, nonsynchronized jaw clutch assemblies (56, 58, 60) while the auxiliary section utilizes resiliently shifted blocked jaw clutch assemblies (114, 116, 118, 120). The blocked jaw clutch assemblies are provided with ramps (176, 178, 180, 182) which will cause unblocking during a clutching operation if the main section is not engaged.

    摘要： A multiple substantially identical countershaft (16, 16A), simple change gear transmission (10) having two-piece (20, 20A, 22, 22A) countershafts is provided. The use of two-piece countershafts allows the countershafts to be supported by three bearings (72, 74 and 76) while not requiring greater than normal manufacturing accuracy of the transmission housing (H). A driving connection between the front and rear countershaft portions is utilized which will allow a degree of axial misalignment between the front and rear portions and which when connected assures proper circumferential alignment of the countershaft gears. In the preferred embodiment, proper circumferential alignment of the front (20, 20A) and rear (22, 22A) countershaft portions is assured by providing a splined connection between the countershaft portions wherein the number of spline teeth (37, 66) is evenly divisible into the number of countershaft gear teeth carried by any gear on one of the countershaft portions (22, 22A) and wherein each spline tooth carried by the one countershaft portion has the same circumferential alignment with the countershaft gear teeth carried by said one portion as all of the other spline teeth carried by the one portion.

    摘要： Improved blocker and jaw clutch means for shiftable change speed gearing is provided for effecting engagement of the low speed gearing of a simple transmission, or the low speed gearing of the main transmission section of a splitter type compound transmission. A transmission having an input shaft driven by a one-way prime mover, a main shaft and at least one countershaft, and including pairs of shiftable gears arranged on and cooperatively between said shafts, is provided with positive clutches, preferably spring loaded jaw clutches, for effecting connection to one of said shafts of a selected one gear of a selected one of said pairs of said gears upon the achievement of substantial synchronization between such gear and such shaft. Blockers are provided for protecting the positive clutch teeth from excessive wear during such shifting. At least one of said jaw clutches, preferably the jaw clutch for engaging the low speed pair of gears in a simple transmission, or the jaw clutch for engaging the low speed pair of gears in the main transmission section of a splitter type compound transmission, is provided with an improved blocker effective to sense only one type of nonsynchronous condition, namely, that condition corresponding to one of the clutch members overspeeding the other clutch member but not effective to sense the other clutch member overspeeding the one clutch member. The provision of improved blockers effective to sense only one type of nonsynchronous condition, and effective to prevent or block a clutch engagement only upon the sensing of that one type of nonsynchronous condition, is an improvement since the possibility of such blocker being incorrectly positioned or sensing a false nonsynchronous condition is substantially reduced or eliminated.
