Abstract:
The present invention encompasses a transmission arrangement (1 ) for translating a reciprocating translation movement, related to each of two gear rods (51 , 52), in mesh with its allotted gear wheel (10', 11 '), where a first gear rod and its associated first gear wheel (10') is representing a first prime motor arrangement (10), while a second gear rod and its associated second gear wheel (11 ') is representing a second prime motor arrangement (11 ), including its related freewheel bearing (7, 8). A gear wheel arrangement (4, 5, 6), including bevel gear wheels, is adapted to expose a first bevel gear wheel (4) in cooperation with said first gear wheel (10'), a second bevel gear wheel (6) in cooperation with said second gear wheel (11 ') and a third bevel gear wheel (5) adapted to mesh with said first and second gear wheels (4, 6), in order to adapt or to cause these first and second bevel gear wheels (4, 6) in different rotational directions. Said first bevel gear wheel (4) and its associated first gear wheel (10'), related to said first prime motor arrangement (10), are integrally formed as to form one first unit (100). Said second bevel gear wheel (6) and its associated second gear wheel (11 '), related to said second prime motor arrangement (11 ), are integrally formed as to form one second unit (200). Said first unit (100) and said second unit (200) are, via its related freewheel bearing (7, 8), pivotally supported by said shaft (2) at a first pivotal direction and fixedly or blockingly supported by said shaft (2) in an opposite second pivotal direction. Said first (100) and second (200) units are identically formed.
Abstract:
This invention relates to sets of driving and driven gears including non-circular gears or Geneva pin and wheel mechanism that work together like a continuously variable transmission that is non-dependent on friction. Since a chain and sprocket system operates like a cone and belt system and the driving and driven gear system, though discrete, shifts ratio without interruption they can be viewed as Pseudo Continuously Variable Transmission. With the use of a planetary gear system, it allows the output to be continuous from forward to reverse including neutral. With segmentation of the circular and non-circular gears upshift and downshift are achieved by briefly passing the power train via a non-circular gear to the next gear ratio during the transition. This invention also offers several ways to achieve uninterrupted shifting capability for a multi-speed transmission eliminating the need for synchronizers and directly connecting to their respective shaft via a dog clutch or similar device.
Abstract:
The method converts bi-directional torque to unidirectional torque. The bi-directional torque comprises a first rotational drive (17) in one direction alternating with a second rotational drive (18) in the other direction along a drive axis which is converted to become unidirectional torque along a driven axis (20). At least a first and a second unidirectional element (9a, 9b) are provided at any one or combination of said drive (12) or driven (20) axes.
Abstract:
Ein Zahnradgetriebe (1) mit einem Gehäuse (2), einer Antriebswelle (3) und einem Abtriebszahnrad (5) umfasst einen Getriebemechanismus mit einem Taumelkörper (9), der bei Drehung der Antriebswelle (3) eine Taumelbewegung ausführt, die in eine Drehung des Abtriebszahnrads (5) überführt wird. Ein erstes und ein zweites Zahnrad (6, 7) sind mit dem Abtriebszahnrad (5) gekoppelt und umfassen jeweils wenigstens einen Freilauf (27, 28, 33, 34) mit einer Sperrrichtung und einer Freilaufrichtung. Eine auf der Antriebswelle (3) drehfest angeordnete Taumelscheibe (10) trägt den Taumelkörper (9) und ist in dem Taumelkörper (9) drehbar gelagert. Ein Neigungswinkel der Taumelscheibe zur Taumelscheibendrehachse (11) ist über Steuermittel einstellbar, um die Taumelscheibe bei drehender Antriebswelle in eine Taumelbewegung zu versetzen und über die Lagerung (16) der Taumelscheibe (10) in dem Taumelkörper (9) eine Taumelbewegung des Taumelkörpers (9) zu verursachen. Der Taumelkörper (9) ist derart mit den Freiläufen (27, 28, 33, 34) gekoppelt, dass eine Taumelbewegung des Taumelkörpers (9) in eine hin- und hergehende Drehbewegung der Freiläufe (27, 28, 33, 34) überführt und eine in die Antriebswelle (3) eingeleitete Antriebskraft auf das Abtriebszahnrad (5) übertragen wird.
Abstract:
The present disclosure relates generally to strut-type overrunning coupling devices. More specifically, the present disclosure is directed to a one-way clutch configured to provide a first or latched mode having the struts engaged with ratchet teeth to establish a one-way torque path, a second or ratcheting mode having the struts ratcheting over the ratchet teeth, and a third or uncoupled mode having the struts moved, via centrifugal forces, to a position displaced from the ratchet teeth.
Abstract:
A variable speed ratio transmission comprises a support structure, an input member, an output member and a plurality of planet wheels which are supported rotatably on the support structure and which receive the movement from the input member. Each of the planet wheels comprises a connecting rod which is rotatably connected thereto in the region of a first end thereof and which supports at an opposite end thereof a unidirectional connection wheel which entrains in rotation the output member. The transmission further comprises a variation device for the spacing between the pivot axis of the connecting rods and a respective rotation axis of the planet wheels.

A lever type power transmission device of a bicycle, wherein a large force can be developed with a small force by the power point and application point of a lever by the principle of a lever, the positive magnetic poles of magnets generate a magnetic force, and these two actions are combined with each other, wherein the device is installed on a frame of the bicycle so as to be interlocked to forward and backward wheel gears, whereby a bicycle pedal working pressure can be reduced and stable propelling of the bicycle can be persistently performed so as to reduce fatigue.
Abstract:
A variable transmission that is small in size, light in weight, simple in construction, secure in operation, long in service life and capable of high-output speed changes. An input shaft crank (3) and an input side member (4) are mounted on an input shaft (1) and an output shaft (2) via a one-way clutch mechanism (100), respectively, and the respective members are coupled to each other by means of an input connecting rod (5) and an output connecting rod (6). Also, a speed-change link (7) is coupled to a junction point (B) of these links at one end thereof, and the other end thereof (Q) is allowed to move to any position within a certain range and to be fixed at that point. Also, the one-way clutch is a rolling bearing clutch. Variable speed change can securely be obtained with a simple mechanism. In a case where a rolling bearing clutch is used, high-output speed change is possible with a transmission that is small in size and light in weight.
