摘要： A torque transmission mechanism (1) comprises an outer body (10) defining a cavity (12) and an inner body (30) located at least partially inside the cavity and able to rotate therein. A plurality of rollers (22, 24, 26) located between the outer and inner bodies interact with cam surfaces (14a, 16a, 18a, 20a) so that rotation of the inner body in a first direction is substantially unimpeded but rotation in the opposite direction is prevented or impeded by interaction of rollers with one or more cam surfaces. One of the rollers (18) is larger than at least one other roller and is located in a recess formed in one of the outer and inner bodies. In one embodiment the recess (18) is formed in a part of the outer body which has a greater wall thickness, excluding the effect of the recess than the rest of the outer body, so that the larger roller is accommodated without adding bulk to the outer body.

摘要： A reversible wrench includes a handle and a carrier arranged on the handle. A torque transmission assembly is arranged in the carrier. The assembly includes an inner driven member having an inner, outwardly facing bearing surface and an outer driving member having an outer, inwardly facing bearing surface, the driven and driving members being arranged in the carrier about a common rotation axis and the surfaces being spaced from each other. A selector is positioned between the bearing surfaces. At least one motion transfer device is positioned between the bearing surfaces. The bearing surfaces, the selector and the at least one motion transfer device define at least two roller bearing passages. At least one roller bearing is positioned in each passage. The roller bearings can be shifted between a tightening condition in which the roller bearings lock the bearing members together for tightening rotation of the carrier and a loosening condition in which the roller bearings lock the bearing members together for loosening rotation of the carrier. Opposite rotation of the carrier with respect to the tightening and the loosening rotation, respectively, unlocks the roller bearings to permit freewheeling of the carrier during the opposite rotation. The selector and the at least one motion transfer device are configured so that the selector is operable to shift the roller bearings between the tightening and loosening conditions, via the at least one motion transfer device. A biasing mechanism is operatively arranged with respect to the roller bearings so that the roller bearings are unlocked against a bias of the biasing mechanism during the opposite rotation and are driven back into one of the tightening and loosening conditions upon ceasing of the opposite rotation.
