摘要： A control device of an internal speed change device of a wheel hub for clutching operation includes a rod; a lever installed on the rod; the lever being connected to a controlling claw sliding block; an electric sliding block installed on a lever sleeve; the lever sleeve serving to receive a back end of the lever; an electric bushing located at an outer side of the lever sleeve; a controlling ring located at an outer side of the electric bushing; and wherein force of attraction or repulsion between the controlling ring and the electric sliding block drives the electric sliding block to rotate or move axially so as to drive the lever to move forwards or backwards axially; and moving of the lever drives the controlling claw sliding block to control clutching of the internal speed change device.

摘要： The present invention comprises: a synchronization start determination unit 110 for determining a synchronization start of a synchronization device 70; a half-clutch determination unit 130 for determining whether a clutch device 20 is in a half-clutch state where the clutch device has not been switched from a connection state to a disconnection state; and a damage determination unit 140 which, when the synchronization start determination unit 110 has determined the synchronization start and if the half-cutch determination unit 130 has determined a half-clutch state, determines that damage is applied to the synchronization device 70 caused by the differential rotation between the power transmitted from a driving force source 10 side via the clutch device 20 and the power transmitted from a driving wheels 16L, 16R side.

摘要： A lay-shaft assembly for use in a vehicle transmission, including a lay-shaft which is rotatable around a central axis, a first gearwheel rotatable around the lay-shaft and the central axis, a second gearwheel fixedly connected to the lay-shaft and rotatable with the lay-shaft around the central axis, and a clutching assembly rotatable around the lay-shaft and the central axis. The clutching assembly includes a driven gearwheel and clutching mechanism for selectively coupling the rotation of the driven gearwheel to either the first gearwheel or the second gearwheel. The clutching assembly has a first axial end and a second axial end opposite the first axial end. The first gearwheel and the second gearwheel are arranged on a part of the lay-shaft extending from the first axial end of the clutching assembly.

摘要： A transmission for a motor vehicle is provided. The transmission has a hydraulically or electrically operable gearshift sleeve, a clutch pack, an input shaft, and an output shaft, a gearshift sleeve, a gearshift sleeve claw, and an opposing output claw associated with the output shaft. The gearshift sleeve can be moved from an initial position into a first position, in which the gearshift sleeve transfers an axial force by way of the first ramp element and the second ramp element to the clutch pack for synchronization of the disks, and into a second position, in which the gearshift sleeve claw is connected to the output claw interlockingly in the direction of rotation and thus the input shaft and the output shaft are interlockingly coupled. A method for shifting such a transmission is also provided.

摘要： Systems and method for a two-way clutch are provided. In some configurations, the two-way clutch includes a driven member having a first mating surface, a drive member having a second mating surface, and a locking mechanism arranged between the first mating surface and the second mating surface. The locking mechanism is operable to contact the first mating surface and the second mating surface, in response to an outside force applied to the drive member that loads the locking mechanism. The two-way clutch further includes an engaging member. The engaging member provides a predetermined interference on the locking mechanism to hold the locking mechanism off of at least one of the first mating surface and the second mating surface, when the locking mechanism is in an unloaded state.

摘要： A transmission includes a first component and a second component which are journaled for rotation relative to each other, and a locking mechanism for rotationally locking the first component and the second component relative to each other in a predetermined mutual rotation position. The locking mechanism includes a sleeve and a dog clutch, the sleeve being rotationally locked relative to the first component and the dog clutch being rotationally locked relative to the second component, the sleeve and the dog clutch being axially displaceable relative to each other for engagement of the sleeve and the dog clutch such that the first component and the second component are rotationally locked relative to each other, the sleeve and the dog clutch being engageable only in a mutual rotation position corresponding to the predetermined mutual rotation position of the first component and the second component.

摘要： A synchronizer ring is made of steel and has a main body with a conical friction surface. A toothing and at least one blocking body project radially outward from the main body. The blocking body has an engagement section extending in the axial direction. The engagement section has a first edge, which runs approximately parallel to a first end face of the main body and has a first width extending in the circumferential direction, and two mutually opposite second edges extending from the first edge. To improve the durability of the synchronizer ring, the second edges have a convex curvature in a plan view of the engagement section. A second width extending in the circumferential direction between the second edges is greater than the first width at a depth spaced apart from the first edge.

摘要： A method for providing artificial lift with an electric submersible pump system includes providing an electric submersible pump system having a motor, a pump assembly, a seal assembly, and a shaft assembly extending along a central axis from the motor to the pump assembly. The pump assembly includes two or more pump sections and a coupling with a transmission mechanism is located between the two or more pump sections. The motor rotates a motor shaft segment of the shaft assembly that is in engagement with a first pump section and starts the first pump section. One of the transmission mechanisms is moved from a disengaged position to an engaged position where the coupling conveys the rotation of the motor shaft segment to the adjacent shaft segment and starts another of the two or more pump sections.
