Abstract: A CVT drive train including an input drive, a torque converter is downstream from the input drive in a power flow direction and contained within a torque converter housing, the torque converter serving as a starting element. A disconnect clutch is contained within the torque converter housing along with a converter bridging clutch. A continuously variable variator is operatively connected to and arranged downstream from the torque converter, and a rotation reversing device is downstream of the variator to enable a shift between a neutral position of the drive train and one of a forward driving position and a reverse driving position.

Abstract: A CVT drive train including a continuously adjustable variator and having a transmission input shaft situated on a primary drive side of the drive train and operatively connected with a primary drive source that is an internal combustion engine. A start-up device and a secondary drive source that includes an electrical machine are disposed co-axially. A first additional clutch serves to couple the secondary drive source to a direct drive stage, and a second additional clutch serves to couple the secondary drive to the variator input.

Abstract: A CVT drive train having an input drive, a start-up element, a continuously variable variator, and a differential. A direct shifting stage bridges the variator and is connected directly to the input drive. The direct connection of the direct shifting stage to the input drive enables the direct shifting stage to be used advantageously independently of the start-up element and can be connected, for example, to a gear that is used in conventional CVT drive trains to drive a hydraulic pump.

For the first operating range (low) the sub-transmission includes a non-positive clutch, such as a friction clutch, and for the second operating range (high) it includes a positive clutch, such s a jaw clutch.

Abstract: A CVT transmission including a start-up element, a variator, and a direct-shift stage for switching between a first operating range (low) and a second operating range (high). A maximum transmission ratio of the second operating range (high) corresponds to a minimum transmission ratio of the first operating range (low). The transmission ratio ranges are arranged so that the marginal variator transmission ratio ranges, which constitute low-efficiency ranges, are not used.

The drill point is arranged eccentrically relative to a central axis, which is the same as the axis of rotation. The second major cutting edge is arranged by a cutting-height difference higher than the first major cutting edge. The first major cutting edge has a shorter radial edge length than the second major cutting edge. A method of utilizing the tool is also disclosed.

Abstract: A conical disk assembly including a shaft carrying an axially movable disk and having a fixed disk rigidly connected to the shaft. A support ring having first ramp surfaces facing the axially movable disk is carried on the shaft, and a rotatable sensing piston having second ramp surfaces that face the first ramp surfaces is axially movable along the shaft. Rolling elements are positioned between the ramp surfaces, and when the ramp surfaces are rotated relative to each other, the rolling elements move the sensing piston axially along the shaft. A guide ring is rigidly operatively connected to the axially movable disk and includes guide surfaces associated with the ramp surfaces for radially supporting the rolling elements. The guide ring and the support ring are connected with each other in a non-rotatable and axially movable manner to facilitate assembly of the conical disk assembly.

Abstract: A method for regulating or controlling the transmission ratio of an automatic power-branched transmission. Power is transmitted through a shaft driven by an engine, a variable speed drive, a gear transmission, a driven shaft, and at least two control clutches. The variable speed drive and the gear transmission are connected to each other in such a way that the regulating range of the variable speed drive is traversed in one direction within a first range of transmission ratios, and is traversed in the opposite direction within a second range of transmission ratios during traversing of the entire range of transmission ratios. The shifting strategies result in reduced wear of the endless belt device and allow for comfortable changing between the transmission ratio ranges.

Abstract: Rotatable conical disks for a belt-driven conical-pulley transmission. The conical disks have conical surfaces that inclined relative to a conical disk axis of rotation and have surfaces that are induction hardened together with or separate from a shaft component. The induction hardened surfaces of the conical disks include regions of the disk surfaces that are frictionally engaged by an endless torque-transmitting component. The shaft component is induction hardened in regions that experience high mechanical stresses as a result of axial loads imposed on the conical surfaces of the disks by the endless torque-transmitting component.

Abstract: A method and a system for reducing a jerk produced by the range shift of a transmission with a power division arrangement. The transmission includes a variable speed drive in the form of a continuously variable transmission, and a pair of planetary gear sets and a pair of shift clutches to enable power to be divided between two branches within the transmission. During a range shift between two operating ranges the variable speed drive is acted upon by a short-term transmission ratio adjustment impulse in such a way that a cancellation jerk caused thereby the adjustment impulse weakens the jerk caused by the range shift.
