A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

Provided is a driving apparatus that can be miniaturized while maintaining necessary output. A driving apparatus (1) comprises a motor (10), an intermediate gear train (20) including at least one gear that transmits power generated by the motor (10), and an output shaft (30) to output driving power to outside. Furthermore, the driving apparatus (1) comprises a torque limiter (40) provided between the intermediate gear train (20) and the output shaft (30), to enable cutoff of the transmission of the power between the intermediate gear train (20) and the output shaft (30), and a planetary gear mechanism (50) provided between the torque limiter (40) and the output shaft (30). The planetary gear mechanism (50) is disposed in parallel with the motor (10).

The present disclosure relates to a hydraulic transmission assembly comprising: a hydraulic transmission for performing speed shifting for the power generated by an engine; a pump shaft connected to the pump; a motor shaft connected to the motor; a sub speed-shift shaft connected to the pump shaft and/or the motor shaft through a plurality of speed-shift gears; a mounting main body having a mounting space for the hydraulic transmission; a speed-shift case having an accommodation space for the sub speed-shift shaft, and coupled to the mounting main body; and a cover part coupled to the mounting main body so as to cover the mounting space, wherein the cover part is coupled to the mounting main body such that at least a portion thereof is accommodated in the mounting space, and provides support power to one side of the sub speed-shift shaft.

A rotating machine and a pinion shaft are separately arranged on opposite sides to each other in the vehicle front-rear direction across a third axis that is an axis of a differential device in plan view as seen from above the vehicle. This configuration enables the rotating machine, a parallel shaft transmission, the pinion shaft, the differential device, and others to be integrally assembled to a case, to thereby configure an electric drive unit to be compact, which is advantageous in space.

A gear system includes a housing part. The housing part has a cylindrical inner wall which radially surrounds the wheel, e.g., toothed part, such as a gear, connected to the output shaft of the gear system for conjoint rotation. On the cylindrical inner wall are formed projections, which are spaced from each other in the circumferential direction, e.g., are spaced from each other at regular intervals, and which project radially inwards and extend axially. For example, the projections are longer in the axial direction than in the circumferential direction and in the radial direction.

The present disclosure relates to a mechatronic actuator consisting of a housing incorporating a shell and a three-phase electric motor formed by a stator excited by electrical coils and by a magnetized rotor, driving an output shaft by means of a gear train, the axis of the rotor, the axis of the output shaft and the axes of the intermediate toothed wheels being parallel, the stator having a radial triangular star shape, the three wound poles forming the three branches of the star, the axes of symmetry of two consecutive wound poles forming a mechanical angle of 120°, the housing also incorporating an electronic circuit, including a capacitor for filtering the electrical signal, the shell having a longitudinal axis, characterized in that the stator is positioned in the hosing in such a way that the axis of symmetry of one of the three wound poles forms an angle of between 70 and 110° with the longitudinal axis.

A robot joint includes a casing, a motor assembly including a stator and a rotor that are arranged within the casing, and a harmonic drive received, at least in part, in the rotor. The harmonic drive includes a circular spline, a wave generator fixed to the rotor, and a flex spline. The circular spline is arranged around and engaged with the flex spline. The wave generator is received in the flex spline and configured to drive the flex spline to rotate with respect to the circular spline. The robot joint further includes an output shaft fixed to the flex spline.

A transmission includes an input shaft and an output shaft, the input shaft selectively accepting a torque input from a prime mover, and the output shaft selectively providing torque output to a driveline. A controller determines a shaft displacement angle representing an angle value of rotational displacement difference between at least two shafts of the transmission, and performs a transmission operation responsive to the shaft displacement angle.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

A continuously variable transmission has an oil pan, an oil strainer located above the oil pan and a control valve unit located above the oil pan. The control valve unit has a shape having a cutting portion formed by a part of the control valve unit being cut out when viewed from an oil pan side. The oil strainer is arranged so as to overlap the cutting portion. With this structure, it is possible to ease a restriction on layout in terms of a height direction in the continuously variable transmission.
