  • Patent number: 10190678
    Abstract: A twin-clutch transmission that can always effectively reduce gear shift shock and a collision sound even under the existence of variation attributed to component tolerance and change over the ages attributed to wear. A twin-clutch transmission calculates a rotational speed difference (|Na?Nb|) between an odd-stage main shaft rotational speed (Na) and an even-stage main shaft rotational speed (Nb) and learns synchronization start gear shift drive displacement (?s) detected by a gear shift drive displacement detecting unit at the timing at which the rotational speed difference (|Na?Nb|) reaches a predetermined synchronization start determination rotational speed difference (Ds) from gear shift start. The twin-clutch transmission controls an actuator on the basis of the learned synchronization start gear shift drive displacement (?s).

    Abstract: A dual clutch assembly includes a housing, an actuation member rotationally coupled with the housing, a first member coaxial with the housing, and a second member coaxial with the first member. A first clutch includes a first plate connected with the actuation member and a second plate connected for common rotation with the first member. A second clutch includes a first plate connected with the housing and a second plate connected for common rotation with the second member. At least one first lever is pivotally coupled to the housing. The first lever is pivotable to contact the actuation member thereby translating the actuation member and the first plate towards the second plate in order to engage the first clutch. The second lever is pivotable to contact the first plate of the second clutch and translate the first plate towards the second plate in order to engage the second clutch.

  • Patent number: 8297424
    Abstract: A self-adjusting twin or dual dry clutch assembly for a dual clutch transmission includes a single actuator. The clutch assembly includes one center and two outer clutch drive plates or discs which independently engage a pair of interleaved driven clutch plates or discs which are coupled to and drive a respective pair of transmission countershafts or layshafts. The single actuator translates an internal clutch carrier which acts upon the outer clutch plates through respective pluralities of linear one way clutches. Self-adjustment of the dual clutch assembly is achieved by additional linear one way clutches acting through pairs of spring biased control rods.

  • Patent number: 8276726
    Abstract: A gearbox shifting point for producing a rotationally fixed connection between at least one gearwheel and one shaft. The gearbox shifting point comprises a shaft, a shifting sleeve and two gearwheels. The two gearwheels are each rotatably mounted in relation to the shaft. The shifting sleeve is mounted in a rotationally secured fashion on the shaft. The shifting sleeve and the gearwheels are embodied in such a way that a positively locking, rotationally fixed connection can be produced between the shifting sleeve and in each case one gearwheel. In order to improve problems with respect to a gearshifting hole or blockage of the gearbox, the shifting sleeve interacts with the two gearwheels in such a way that at least one positively locking, rotationally fixed connection is always produced between the shifting sleeve and one of the gearwheels.

  • Patent number: 8245828
    Abstract: A device for rotationally fixing a shaft to a component that is rotatably arranged on the shaft. The actuating element positively engages the components to rotationally fix the components to the shaft. The difference in rotational speeds, between the component and the shaft, can be at least approximately compensated for by the actuating element. The actuating element, for rotationally fixing the component to the shaft by the actuator, is operatively connected to at least one support body, which is rotationally fixed with respect to the shaft in such a manner that the actuating element can act upon the component with an actuating force that depends on the torque to be transmitted from the shaft to the component and which is independent of the actuation of the actuator in the state in which the actuating element can be rotated relative to the shaft.

  • Patent number: 8196725
    Abstract: A device for connecting, in a rotationally fixed manner, a shaft to at least one component which is rotationally supported on the shaft, such as a gear wheel of a gear in a transmission. The device includes an actuating element that is rotationally fixed, but axially slides on the shaft, such that when the element is actuated by an actor, the element actively, frictionally communicates with the component to at least approximately equalize a rotational speed difference, between the component and the shaft. The actuating element can be actuated by the actor with a force to frictionally connect the component to the shaft in a rotationally fixed manner. The device further includes a holding device, which retains the actuating element in a shift condition essentially equivalent to the rotationally fixed condition of the component without further actuation of the actor.

  • Patent number: 8167104
    Abstract: The invention relates to a gear shifting point (10) for producing a rotationally fixed connection between a toothed wheel (16, 18) and a shaft (12). Said gear shifting point (10) comprises a shaft (12), a sliding sleeve (24) and at least one toothed wheel (16, 18). The toothed wheel (16, 18) is mounted rotationally with respect to the shaft (12). The sliding sleeve (24) is mounted on the shaft (12) in such a way that it is not rotatable therewith. The toothed wheel (16, 18) and the sliding sleeve (24) are embodied in such a way that a rotationally fixed connection can be produced therebetween in the coupled state of the gear shifting point (10) and no connection can be produced between the toothed wheel (16, 18) and the sliding sleeve (24) in the neutral state of the gear shifting point (10).
