  • Patent number: 10696370
    Abstract: Transmission systems and methods are for a marine propulsion device having an internal combustion engine that drives a propulsor. An input shaft is driven into rotation at a non-zero first rotational speed by the internal combustion engine. An output shaft drives the propulsor into rotation at a non-zero second rotational speed. A planetary gearset transfers power from the input shaft to the output shaft. A band brake is on the planetary gearset. Actuation of the band brake effects a gear change in the planetary gearset. A band brake actuator actuates the band brake to effect the gear change. A controller controls the band brake actuator. Based upon one or more operational characteristics of the marine propulsion device the controller is programmed to control the band brake actuator so that the second rotational speed is less than the first rotational speed.

  • Patent number: 10683912
    Abstract: A planetary gear mechanism includes a plurality of planetary gear units each including a sun gear member to be rotationally driven by a driving source, an internal gear member, planetary gear members, and a carrier member, and a case body that internally houses the planetary gear units and includes an inner circumferential surface to be brought into surface contact with outer circumferential surfaces of the internal gear members. Engagement portions having concave shapes or convex shapes that can be fitted to convex shapes or concave shapes formed in the outer circumferential surfaces of the internal gear members are formed in the inner circumferential surface of the case body. The engagement portions are engaged with the convex shapes provided in the outer circumferential surfaces of the internal gear members, from an opposite direction to a rotating direction of the carrier members, to thereby inhibit the internal gear members from rotating.

  • Patent number: 10661800
    Abstract: A drivetrain for an agricultural vehicle and method for controlling the same. The drivetrain includes first and second driven axles with a variable pivot angle hydraulic motor connectable to drive the first axle through engagement of a first clutch mechanism. A further motor is connected to drive the second axle. In operation, the pivot angle of the variable pivot angle hydraulic motor is reduced with variation in a vehicle parameter value, such as transmission ratio or ground speed, to a point at which the pivot angle reaches zero at a first parameter value. With the pivot angle at zero and parameter value continuing to vary due to the drive of the further motor, the first clutch mechanism is disengaged at a second parameter value, with the first and second parameter values separated by an interval determined at least partly by an operating characteristic of the first clutch mechanism.

  • Patent number: 10663038
    Abstract: Provided herein are a transmission method and a device for coaxially outputting autorotation and revolution. The axis of a power output shaft (17) and the axis of a crank of a power input shaft (1) are coincided with each other. The power output shaft (17) revolves around the axis of a main shaft of the power input shaft (1), and the revolution speed equals to the rotation speed of the power input shaft (1). After the superposition of a transition gear train (A) and a K-H-V few-tooth-difference planetary gear train (B), a driving force of the power input shaft (1) enables the power output shaft (17) to generate the autorotation which has the same speed as that of the power input shaft (1) but in the opposite direction, and at the same time, a thrust bearing (19) coaxial with the power output shaft (17) is connected to a thrust bearing (18) coaxial with the main shaft of the power input shaft (1) in series to bear axial loads.

  • Patent number: 10648555
    Abstract: A method of controlling the gear shifting of an automatic range-change transmission, which is arranged between a drive engine and a final drive in a drive train of a motor vehicle and includes at least one multi-stage main transmission, a two-stage front-mounted group upstream of the main transmission, and a transmission brake. The main transmission can be shifted, via unsynchronized clutches, and the front-mounted group can be shifted, via synchronized clutches. Upon upshifting in the range-change transmission including at least one change of a transmission ratio stage of the front-mounted group, synchronization of the front-mounted group is effected via actuation of the synchronized clutch of the front-mounted group and supportingly via at least intermittently parallel actuation of the transmission brake. Actuation of the transmission brake, for supporting the synchronization of the front-mounted group, is effected on the basis of a prevailing driving or operating situation.

  • Patent number: 10612641
    Abstract: The present invention relates to a ring gear and a gear reduction device. The ring gear includes an annular body with a plurality of mounting portions, and a plurality of teeth arranged on an inner circumferential surface of the annular body. The annular body and the teeth are integrally formed from powder metal, and the mounting portions and the teeth are at least partly overlapped in an axial direction of the annular body. The mounting portions are integrally formed with the annular body and the teeth, which results in concentricity between the mounting portion and the teeth being improved and cost of the ring gear being reduced. Furthermore, the mounting portions are overlapped with the teeth, which reduces the axial size of the ring gear.
