摘要： In some examples, a cone clutch assembly includes an inner cone member rotationally coupled to a first shaft, the inner cone member defining a first friction surface, and an outer cone member rotationally coupled to a second shaft, the outer cone member defining a second friction surface opposing the first friction surface. The inner cone member and outer cone member are configured to be selectively engage and disengaged from each other. When the inner cone member is engaged with the outer cone member, the first friction surface of the inner cone member frictionally engages the second friction surface of the outer cone member such that rotational motion is transferred between the inner cone member and the outer cone member. The inner surface of the inner cone member opposing the first friction surface includes at least one groove configured to receive a cooling fluid during operation of the cone clutch assembly.

摘要： A friction part for a frictionally operating device includes an annular-disc-like friction surface rotatable about a rotational axis in a wet-running manner relative to a mating surface. The annular-disc-like friction surface is formed from a paper material and includes a meso-geometric or a micro-geometric uneven portion in order to create an axially deep friction region and an axially high friction region in the annular-disc-like friction surface. The axially high friction region is more strongly preloaded than the axially deep friction region when the annular-disc-like friction surface and the mating surface are axially pressed together.

摘要： In examples, a cone clutch assembly includes an inner cone member rotationally coupled to a first shaft, the inner cone member defining a first friction surface; and an outer cone member rotationally coupled to a second shaft, the outer cone member defining a second friction surface opposing the first friction surface. The inner cone member and outer cone member may be selectively engaged and disengaged from another. When the inner cone member is engaged with the outer cone member, the first friction surface of the inner cone member frictionally engages the second friction surface of the outer cone member such that rotational motion is transferred between the inner cone member and the outer cone member. The inner cone member includes at least one hole including an inlet near a front edge of the inner cone member and that extends through the inner cone member adjacent to the first friction surface.

摘要： The present invention relates to a coupling arrangement (24) comprising a first part (12), which defines a longitudinal axis (L), a second component (14), which is displaceably mounted along the longitudinal axis (L), a press-on element (16), which pretensions the second component (14) in a first position, in which the second component (14) is in frictional engagement with the first component (12), and an actuating unit (18), with which the second component (14) can be displaced from the first position in a second position, in which the second component (14) is distanced from the first component (12), wherein the actuating unit (18) comprises an actuator (20), which is displaceable along the longitudinal axis (L) and thereby provides an opening force, and a lever (22) which is rotatably mounted in the second component (14) about an axis of rotation (D) that is perpendicular to the longitudinal axis (L), and has a contact surface (26), with which the lever (22) is in contact with a fixed mating surface (28), wherein the contact surface (26) and/or the mating surface (28) has a convex curvature (30), and the actuator (20) and the lever (22) cooperate in such a way that the movement of the actuator (20) along the longitudinal axis (L) is converted into a movement of the lever (22) on the mating surface (28), whereby the second component (14) is displaced along the longitudinal axis (L) in the second position.

摘要： A load connecting mechanism includes a mounting portion, a contact portion, and a force-exerting portion. The mounting portion is configured to mount the load connecting mechanism to a power source and a load, respectively. The contact portion is disposed on the mounting portion and includes two slidably coupled contact faces. The force-exerting portion is configured to provide a force to the contact faces in an axial direction of the power source to make the contact faces closely slidably couple to each other. Through the slidable coupling relationship between the contact faces, power of the power source is progressively transmitted to the load and finally drives the load to rotate in synchronization with the power source. The present invention further provides a motor driving assembly and a fan. The mechanism can satisfy the needs of bidirectional rotation of a load such as a fan and of large startup torque.

摘要： Friction ring for a synchronization unit of a gear changing transmission. The friction ring, when in an uninstalled state, is circumferentially pre-loaded and includes an annular front side, an annular rear side, a conical inner friction surface, a conical outer installation surface, and a first separation surface facing and in contact with a second separation surface and defining a circumferential separation area in the friction ring. The friction ring is prevented from contracting radially and circumferentially by said contact and is capable of expanding radially and circumferentially while being circumferentially pre-loaded.

摘要： A gear shifting control method for an electric vehicle includes an operation range determination step of determining, by a controller, whether a current revolutions per minute (RPM) of a motor falls within a constant torque range or a constant power range when gear shifting is initiated between a first shift gear and a second shift gear. A variable control step controls an operating power of a cone clutch by adjusting an operating tilt if it is determined that the RPM of the motor falls within the constant torque range in the operation range determination step. A constant control step controls the operating power of the cone clutch to be constant if it is determined that the RPM of the motor falls within the constant power range in the operation range determination step.
