    Abstract: A friction drive (10) having a plurality of planet assemblies (24A, 24B, 24C) pivotally mounted to a carrier (12), a sun shaft (14) rotatably mounted with the carrier (12) and having a first raceway (16), and an outer ring member (18) having a second raceway (22) concentric to the first raceway (16) and having a ring shaft (20). The plurality of planet assemblies (24A, 24B, 24C) frictionally engaged with the first raceway (16) and the second raceway (22) for transferring power between the sun shaft (14) and the outer ring member (18).

    Abstract: A wheel end (A) has a housing (2, 70, 80, 90) and a hub (4) provided with a spindle (32) that projects into the housing, and the hub rotates relative to the housing on an antifriction bearing (6) located between the housing and hub spindle. The housing has a tubular core (12, 72, 82, 92) that encloses the bearing and ring mounts (14, 74, 84, 94) spaced outwardly from the core and also webs (16,76,86,96) that connect the ring mounts to the core. A road wheel (B) is attached to the hub and rotates with the hub relative to the housing. The housing is secured to a suspension upright (C) at its ring mounts. The core deflects relative to the ring mounts, owning to forces and moments transferred through the bearing from the suspension upright to the road wheel and vice versa, and the magnitude of those forces and moments are reflected in signals derived from strain sensor modules (SM) attached to the webs of the housing.

    Abstract: A method for power management in an electro-mechanical power-split infinitely variable transmission (eVT) designed to be operated within a designated speed ratio range for vehicular applications. The eVT is comprised of an input shaft coupled to the output shaft of a drive engine to receive power, a drive shaft, two electric machines, and a pair of planetary trains each having a sun member, a ring member, a set of planetary members, and a planet carrier. The eVT further contains one or more torque transfer devices to connect or disconnect members of the planetary trains for transferring torque. The drive shaft is coupled with a final drive of a vehicle for delivering or recapturing power to or from the vehicle drive wheels. The two electric machines are interconnected electronically via a power control unit and are coupled respectively with members of the planetary train. The method of power management in the eVT is selected based on the current speed and torque of the input and drive shafts, and upon the desired operating parameters.

    Abstract: An integrated speed reducer and gerotor pump 1 is disclosed. The device comprises a motor 50, a speed reducer 100, and a gerotor pump 200. The motor 50 provides torque at an elevated speed. The speed reducer 100 is coupled with the motor 50 and converts the torque at an elevated speed into torque at a reduced speed. The gerotor pump 200 is coupled with the speed reducer 100 and uses the torque at the reduced speed for pumping fluids.

    Abstract: A method and apparatus for measuring the speed of a target object passing a pair of sensor units (12) displaced apart by a predetermined distant L in the direction of motion of the target object (16). Passage of one or more features of the target object (16) past the first sensor unit (12A) results in the generation of a signal (x1), and passage of the same feature of the target object (16) past the second sensor unit (12B) results in the generate of a second signal, (x2). A signal processor (18) is configured to determine a mathematical correlation between signals (x1) and (x2), and an associated time delay (τ0). The speed (v) of the target object (16) is calculated by the signal processor (18) as the ratio of the predetermined distance (L) to the time delay (τ0).
