  • Patent number: 10851891
    Abstract: A shift drum arrangement includes a shift drum with at least one first shift gate and/or a shift drum path for actuating at least one shift element of a transmission, in particular of a motor vehicle. A blocking device has a blocking gate and a blocking pin which engages in the blocking gate. The blocking gate has a labyrinth contour, and therefore the blocking pin strikes against a stop contour in one direction of rotation of the shift drum and blocks the further rotation of the shift drum. The block is released after the shift drum is partially rotated back in the reverse direction of rotation.

  • Patent number: 10822069
    Abstract: A reverse gear includes an input shaft, a forward clutch, a reverse clutch, an output shaft, a reduction mechanism, and a relay shaft. The input shaft receives rotational power of a main engine. The forward clutch transmits the rotational power of the input shaft as forward output. The reverse clutch transmits the rotational power of the input shaft as reverse output. The output shaft outputs the rotational power transmitted via the forward clutch and the reverse clutch. The reduction mechanism reduces the rotational power of the output shaft and transmits the reduced rotational power to the propeller shaft. The relay shaft intersects the input shaft and relays the rotational power from the forward clutch and the reverse clutch toward the output shaft. The relay shaft and the output shaft are coupled to each other via a pair of intersecting-shaft gears to be able to transmit power.

  • Patent number: 10801608
    Abstract: A harmonic reducer with an oil guiding ring, wherein an oil guiding ring is disposed in an accommodating space of a flexible external gear, and the oil guiding ring is sleeved on a coupling member and located between a first housing and a flexible bearing. Therefore, after lubricant oil is injected through the oil filling hole of the first housing, the lubricant oil enters an annular oil storage groove through the oil inlet holes of the oil guiding ring. When the wave generator rotates, the lubricant oil in the annular oil storage groove is guided to the flexible bearing of the wave generator by the annular wall surface to lubricate the flexible bearing. Therefore, on the basis of effective lubrication, the harmonic reducer can avoid the foreign body impurity caused by insufficient lubrication, and at the same time, does not have to change the original design.
