摘要： A strut (16) for mechanically coupling a first member (12) to a second member (14) in a planar one-way clutch (10) is formed in a progressive die from a length of cold-formed metallic stock material (50) such that the strut's diametrical member-engaging end surfaces (24, 36) are coextensive with a pair of cold-formed surfaces (52) of the stock material. A pair of oppositely-projecting "ears" (28) are integrally formed on the strut proximate to one (24) of its end surfaces at one station (62) of the progressive die. The ears cooperate with a complementary recess (32) within a pocket (22) formed in the first member's planar clutch face (20) to thereby nominally position and maintain the one of the strut's end surfaces within the pocket. A surface (44) on each ear is preferably coined at another station (56) of the progressive die to thereby provide a relief which prevents deleterious contact between the ears and the opposed clutch face (32) of the second member (12).

摘要： s7 In a power-driven tool, in particular an electric tool with a rotary-driven tool holder (4) and a switch-over device for switching between different operating conditions and/or modes, a first, rotatable coupling part (26) of the switch--over-device is provided with locking recesses (29) in which are positioned, serving as locking elements when coupled, roller bodies (30) which are held, non-displaceable circumferentially but movable radially and out of engagement with the locking recesses (29), in a second rotatable coupling part (27). The first and second coupling parts (26,27) are movable relative to each other between a first axial position, in which the roller bodies (30) engage with the locking recesses (29) by means of spring force, and a second axial position. In the second axial position, the roller bodies engage with a smooth rotating surface (28), axially offset with respect to the locking recesses (29), of the first coupling part (26). The locking recesses (29) and the roller bodies (30) form, in the first axial position, in addition to the coupling of first and second coupling parts (26,27), an overload coupling.

摘要： A one-way clutch comprises rollers (3) inclined to the axis of rotation (6) in line contact with both inner and outer contact surfaces (1a)(2a) at least one of which is a mono-hyperkoloid, there being axial biasing means (7). The rollers may be cylindrical (Fig.1), conical (Fig.6), hourglass-shaped (Fig.7) or barrel shaped (Fig. 8).

摘要： This invention is embodied in a mechanical clutch capable of transferring a large force or torque from an input member to an output member by the application of a very small control force or torque. This clutch is capable of performing many non- slipping power engagements per second. When configured as a following mechanical servo, this clutch becomes the crux of a continuously variable transmission (CVT) suitable for automotive use. In such use, mechanical power may be transferred very precisely by a controlling power of much lower level than the power being transmitted through the clutch mechanism. The automotive literature shows many articles which propose 20%-25 % fuel efficiency improvement obtained by using a continuously variable transmission (CVT).
Today's commercial CVT's have a stepless changing mechanical advantage which is a function of variable pitch diameter ratios, as with wide Vee belts, traction drives. All of these have insufficient power ratings for automotive use. The hydrostatic CVT's operate by the exchange of variable fluid volumes, and have power ratings to drive earth movers. But they suffer from low efficiency and high cost.摘要翻译： 本发明体现在能够通过施加非常小的控制力或扭矩将大的力或扭矩从输入构件传递到输出构件的机械离合器中。 该离合器能够每秒执行许多非滑动动力啮合。 当配置为以下机械伺服机构时，该离合器成为适用于汽车使用的无级变速器（CVT）的关键。 在这种使用中，机械动力可以通过比通过离合器机构传递的动力低得多的控制力被非常精确地传递。 汽车文献显示了许多提出通过使用无级变速器（CVT）获得20％-25％燃油效率改进的文章。 今天的商用无级变速器具有无级变速的机械优点，这是可变节距直径比的函数，如宽Vee带，牵引驱动。 所有这些都对汽车使用没有足够的额定功率。 静液压CVT通过交换可变流体体积进行操作，并具有驱动土方机构的额定功率。 但是它们的效率低，成本高。

摘要： A device for the control of a free wheel coupling for a motor vehicle comprises a lock (27) mounted slidingly in a bell (8) integral with the driving shaft (2a) engageable in a cage (12) provided with rollers (24) and oscillatingly mounted in the bell (8) between two limit positions on which the rollers (24) and the bell (12) and in bearing relationship and provide for the rotation coupling of the driving shaft (2a) and the driven shaft (2b), the lock (27) maintaining the cage (12) between a medium position wherein the driven shaft (2b) is idle and one of the limit positions. When in forward gear and outside braking phases, an electromagnet (31) draws the lock (27) in the cage (12). From a predetermined speed, a safety system recouples automatically the driving and driven shafts.

摘要： A clutch assembly includes an inner race, an outer race and a plurality of roller elements positioned radially therebetween. The clutch assembly also includes a cage assembly, a seal and a retaining ring. The cage assembly includes a skeleton coupled to a spring ring having a plurality of radially extending guides arranged to circumferentially space apart each roller element in alignment with cam surfaces formed on the outer race. The guides are resiliently deformable to allow concurrent engagement of each roller element with both the inner and outer races. The seal engages an inner surface of the outer race and an outer surface of the inner race, and is positioned axially outboard of the roller elements. The retaining ring is positioned within ring grooves formed on each of the inner and outer races to restrict movement of the cage.

摘要： Displacement of a switching member in a first direction causes rolling elements of each pair to come out of engagement with an outer peripheral portion or an inner peripheral portion and form clearances therewith, resulting in an OFF state of a driving force transmission apparatus. Displacement of the switching member in a second direction causes a downstream one of the rolling elements of each pair in the direction of rotation to come into zero clearance engagement with the outer peripheral portion and the inner peripheral portion, with a clearance formed between an upstream one of the rolling elements of each pair and the outer peripheral portion or the inner peripheral portion, resulting in an ON state of the driving force transmission apparatus.
