摘要： Claw-type shifting mechanism (5) with a first sliding sleeve (17) and a fixed coupling element (19). In order to produce a passage, the first sliding sleeve (17) and the coupling element (19) each respectively have at least one recess (31, 35) and at least one web section (32, 36), in which the first sliding sleeve (17) and the coupling element (19) can be arranged together radially on the outside on a first shaft. The first sliding sleeve (17) can be displaced along the first shaft and the coupling element (19) can be connected firmly to the first shaft. The drive arrangement (1) comprises at least one drive machine, a transmission with a first shaft, a second shaft and a third shaft, a housing, and a claw-type shifting mechanism (5) of this type.

摘要： A shiftable planetary transmission (1) includes a planet carrier (2), a plurality of planet gears (3) rotatably arranged at the planet carrier (2), a sun gear (4), and a ring gear (5). The sun gear (4) and the ring gear (5) mesh with the planet gears (3). The planet carrier (2) includes at least one connecting element (6), which is axially displaceable therein. The at least one connecting element (6), on a first side of the planet carrier (2), is at least indirectly connected to an actuator (7) and, on a second side of the planet carrier (2), is at least indirectly connected to a first dog element (8). The first dog element (8) is displaceable, by an actuator actuation, between a first shift position and at least a second shift position due to an axial displacement of the at least one connecting element (6) in the planet carrier (2).

摘要： A system and method for modifying a stock transmission is provided. The stock transmission includes an existing ring gear and main shaft. A modified gearset is provided, wherein the modified gearset is capable of replacing a stock gearset that includes at least a stock sun gear and at least a stock pinion gear. The modified gearset includes a replacement sun gear, the replacement sun gear having an increased tooth count and an increased diameter as compared to the stock sun gear. The modified gearset further includes a replacement pinion gear, the replacement pinion gear having a decreased tooth count and a decreased diameter as compared to the stock pinion gear. The replacement sun gear and the replacement pinion gear are capable of meshing with the existing ring gear. Accordingly, the stock transmission performance can be modified with minimal modifications to the stock transmission itself.

摘要： Drive systems or powertrains including transmissions for electric and hybrid electric vehicles are provided. 3-position linear motor, 2-way clutches (i.e. CMDs) are included in the transmissions. An electric 3-speed AMT having a magnetic coupling device such as a magnetic torque converter is provided to magnetically transfer a portion of rotating mechanical energy of an electric powerplant or motor to a transmission output shaft in response to an electrical signal to synchronize angular velocities of the transmission output shaft and an output shaft of the electric powerplant during a change in state of one of the CMDs. Torque is transferred to the transmission output shaft during the change in state.

摘要： Incongruity sense of a driver due to dog clunking noise can be reduced with reduction of dog clunking noise. A fifth-speed driving gear (425) and a sixth-speed driving gear (426) are arranged on a driving shaft (41) along an axial direction. A first slider (451) is disposed to be movable in the axial direction between the fifth-speed driving gear (425) and the sixth-speed driving gear (426). The first slider (451) is not rotatable on the driving shaft (41). In the axial direction, the sum of the widths of the fifth-speed driving gear (425) and the sixth-speed driving gear (426) is smaller than the maximum width of the first slider (451).

摘要： A gear shifting device, having a first, rotatably drivable transmission component, on which a shift element is arranged in a torque-proof and axially displaceable manner, which is axially movable into at least one shift position, in which the first transmission component is coupled in a torque-proof manner with a transmission component that is arranged adjacent to it and is connectable thereon, whereas an axial shift movement of the shift element into the at least one shift position and/or from this through the interaction of one shift pin is able to be triggered with at least one associated groove-like shift gate, which is designed to be changeable in an axial direction, at least in sections. Thereby, the shift element features, on an inner diameter and/or an outer diameter, at least one associated shift gate, while the respective one shift pin is arranged in a radially displaceable manner, and the at least one shift gate is arranged in a radially opposite manner, to the transmission component adjacent to the shift element, and/or that the shift element, on an inner diameter and/or an outer diameter, accommodates the respective one shift pin in a radially displaceable manner, whereas the at least one associated shift gate for the respective shift gate is arranged to be radially opposite to a transmission component located adjacent to the shift element, and that, in each case, a shift pin is movable through an associated actuator in a radial manner between an initial position and a mesh position, in which each shift pin is able to be introduced into the at least one associated shift gate.

摘要： A magnetic actuator includes a collar element (101) and a toroidal coil (103) surrounding the collar element. The collar element is coupled in a torque transferring way to a shaft (108) surrounded by the collar element. The collar element is capable of sliding in the axial direction with respect to the shaft. The collar element includes indentations (102) for locking in a torque transferring way to a counter-part when the collar element is in a first axial position. The collar element includes permanent magnet material (104) for generating an axial force for moving the collar element to the first axial position when the toroidal coil carries electric current flowing in a first direction and to a second axial position when the toroidal coil carries electric current flowing in an opposite direction. Thus, no mechanical elements are needed for moving the collar element in the axial direction.

摘要： A compact clutch which comprises a driven shaft on which the following are mounted: a gear wheel; a driving bush; a driven bush; a coil spring; a first collar with cam surfaces; and a second collar with cam surfaces. The clutch is characterized in that the gear wheel and the bushes are constrained to the driven shaft in the axial direction by means of two stop rings; in that the driven bush is constrained to the driven shaft in the circumferential direction by means of at least one tongue; and in that the tongue ensures engagement between the driven bush and the driven shaft in the circumferential direction, while in the axial direction the driven bush may slide with respect to the driven shaft.
