  • Gear support for mounting a gear and gear having such a gear support
    Patent number: 7337871
    Abstract: A gear support comprises an elongate carrier portion which is oriented along a longitudinal axis, and a flange portion at one end of the carrier portion. The flange portion serves for fastening the gear support to a case of the gear, and a bearing portion in the region of an opposite end of the carrier portion serves for mounting the gear support on the motor vehicle. The carrier portion has two mutually opposite longitudinal spars, between which ribs extend, the longitudinal spars and the ribs being produced in one piece with one another.

  • Variator disk and variator for a toroidal transmission
    Patent number: 7285070
    Abstract: What is proposed is a variator disk for a toroidal variator, in particular for a motor vehicle toroidal transmission. The variator disk has a curved running surface which is oriented coaxially with respect to a variator axis and on which rollers of the toroidal variator can roll. The variator disk having furthermore at least two partial disks which are designed as a traction disk, on which the running surface is formed, and as a supporting disk, respectively. The supporting disk is designed for supporting axial forces applied to the running surface. The traction disk is supported on the supporting disk in the radial direction to the variator axis.

  • Gear support for mounting a gear and gear having such a gear support
    Publication number: 20060157293
    Abstract: What is proposed is a gear support for mounting a gear on a motor vehicle, in particular for axle gears, with an elongate carrier portion which is oriented along a longitudinal axis, with a flange portion at one end of the carrier portion, the flange portion serving for fastening the gear support to a case of the gear, and with a bearing portion in the region of an opposite end of the carrier portion, the bearing portion serving for mounting the gear support on the motor vehicle. In this instance, the carrier portion has two mutually opposite longitudinal spars, between which ribs extend, the longitudinal spars and the ribs being produced in one piece with one another.
