Embodiment 1

[0052] Embodiment 1: One-way transmission mechanism S1 with different shafts and two-way continuous action

[0053] Here, the one-way transmission mechanism S1 is specifically used as the output mechanism of the pulsating continuously variable transmission, but transmission mechanisms such as cranks, connecting rods, cams, or eccentrics, which are known technologies that do not involve the essence of the present invention, are omitted. and speed regulators, etc.

[0054] see image 3 , the output mechanism of the one-way transmission mechanism S1, including two forward-swing overrunning clutches C2 and anti-swing overrunning clutches C3 based on the space wedging friction overrunning clutch C1 with the same working / engagement direction. Wherein, the combination of the force limiting elements 160a and 160b of the clutch C2 is used as the positive pendulum input member 122, which is formed as a rigid body with the swing rod 100, on which a connecting rod 190 for obtaining input...

Embodiment 2

[0064] Embodiment 2: One-way transmission mechanism S2 of coaxial setting type two-way continuous action

[0065] see Figure 4 , the one-way transmission mechanism S2 can be regarded as a modification of the one-way transmission mechanism S1. Among them, the two forward-swing overrunning clutches C4 and anti-swing overrunning clutches C5 based on the space wedging friction overrunning clutch C1 are arranged on the same axis X. For this reason, the two clutches C4 and C5 have mutually opposite working directions and are optimally axially rigidly connected, that is, the positive swing input 122 and the reverse swing input 132 of the two are optimally rigidly integrated into a coaxial rotation The substantially annular pocket-shaped force limiting element 160. Obviously, the two can also be connected only non-rotatably, if desired. In order to realize the meshing connection between the anti-swing output member 134 and the anti-swing shaft 130 to output the anti-swing torque, ...

Embodiment 3

[0071] Embodiment 3: One-way transmission mechanism S3 of coaxial setting type two-way continuous action

[0072] The biggest difference between this embodiment and the preceding embodiments is only that it will figure 1 A set of helical guide teeth 52 and 92 in the shown overrunning clutch C1 are in the form of single or multiple helical teeth, and are continuously arranged on the inner or outer peripheral surfaces of the guide member 50 and the intermediary member 90 facing each other in the circumferential direction, respectively. see Image 6 . The guide tooth may have a cross-sectional shape such as a rectangle, a trapezoid, a zigzag or a triangle. As a result, the overrunning clutches C6-C9 can automatically compensate for wear and have a stable slip angle during the entire life cycle, and at the same time, they can connect three completely symmetrical rings without fixed connection (forming a combined component). The components are configured in the simplest manner ...

Abstract

The invention discloses a one-way transmission device which can convert reciprocating motion / swinging into one-way continuous rotation. Compared with the prior art, the one-way transmission device is mainly characterized in that two forward-swinging and backward-swinging overrun clutches are low-pair-type space-wedged friction overrun clutches which are axially jointed; and forward-swinging input pieces and backward-swinging input pieces of the two clutches are directly and circumferentially fixed and connected along the same axis in a manner of non-relative rotation at least or are directly connected in an outer-gearing manner. In addition, in order to realize the combined output of the two overrun clutches, the one-way transmission device is also provided with at least one transmission connector so as to connect the forward-swinging output pieces / shafts and backward-swinging output pieces / shafts of the two clutches together. Compared with the prior art, the one-way transmission device has the advantages of simple structure, small volume, easiness in manufacture, large torque capacity, automatic wear compensation and long service life and the like, and is an ideal selection of a pulsing-type continuously-variable transmission output mechanism.

Description

technical field [0001] The present invention relates to a one-way transmission mechanism that converts reciprocating swing / motion into continuous power rotation in the field of mechanical transmission, as well as wave energy conversion transmission devices, bicycle drive devices, various human drive devices, wrenches and Screwdriver tools, etc., particularly relate to a one-way output mechanism including an overrunning clutch in a pulse type continuously variable transmission. Background technique [0002] The one-way transmission mechanisms that convert reciprocating swing / motion into continuous output rotation in the prior art generally include ratchet, roller or spline type overrunning clutches. The resulting deficiencies include low load-carrying capacity and impact resistance, limited engagement frequency / operating speed, low working sensitivity due to stepped engagement, and poor performance when speed steps and low-speed small swings occur. It seems too complicated a...
