Abstract: A constant mesh gearbox has five parallel rotational axes. The input and output axes are not aligned. Some torque paths are via a sleeve rotatable on a shaft on one of said axes. Up to eight forward speeds are disclosed, with two very low ratios suitable for non-highway travel. The transmission is suitable for two and four wheel drive.

Abstract: A vehicle transmission includes a housing part, a shaft extending from the housing part, and a spring element having a plurality of spring windings wound around the shaft, a first end of the spring element being fixed to the housing part. An actuating means is attached to a second end of the spring element and is configured to twist the second end in a circumferential direction of the spring element to thereby cause the spring element to tighten and frictionally contact an outer circumference of the shaft. The spring element is comprised of a hollow cylindrical metal base body having a helical-shaped incision that defines the plurality of spring windings. The incision may be formed in the hollow cylindrical base body by a plasma beam process, by a laser cutting process, by a flame cutting process or by a water jet cutting process.

Abstract: An automotive transmission having a hill hold feature, comprising an input shaft arranged to be driven by an engine, an output shaft arranged to transfer drive from the input shaft to driving wheels of a vehicle to which the transmission is fitted, and a transmission housing within which the input and output shafts rotate, wherein a one-way clutch is coupled to the input shaft and the housing to allow rotation of the input shaft in only one direction relative to the housing, such that when a forward gear of the transmission is engaged the vehicle is prevented from rolling backward.

Abstract: In order to avoid a sudden jerk when a vehicle is parked on a slope and its parking pawl engages with a toothed wheel on the transmission output shaft, a method is performed that detects that the vehicle's gear selector has been put into its parking mode and then gradually reduces the brake force until the vehicle starts moving. If the vehicle stops, the brake force will slowly be further reduced until the vehicle has reached its final position.

Abstract: A wheel transmission for a heavy construction vehicle, which can be applied to specially-equipped vehicles as well as heavy construction vehicles such as a forklift truck and a mechanical shovel. The wheel transmission (200) is intended to drive a pair of right and left wheels independently, and includes a planetary gear assembly (210), a change clutch part (230), a one-way clutch part (300), and a brake part (270) housed in an axle hub at which opposite ends of a drive axle shaft are located, turning force from an engine of a heavy construction vehicle being transferred to the drive axle shaft through a torque converter, a driving shaft, a final reduction gear and a differential gear.

Abstract: The hill-holding mechanism of the present invention comprises an apparatus and methodology for actuating a transmission control element to prevent the output shaft of an automatic transmission in a hybrid vehicle from rotating under certain predetermined circumstances.

Abstract: The present invention provides a one-way clutch for an automatic transmission, comprising an inner race, an outer race disposed in coaxial with the inner race and rotated relative to the inner race, recessed portions formed in an outer periphery of the inner race or an inner periphery of the outer race along a circumferential direction, pawls engaged by the recessed portions, and biasing members for biasing the pawls toward the recessed portions, and wherein the outer race is integrally provided on a case of the automatic transmission.

Abstract: A one-way clutch includes a chamber containing a roller that moves in response to changes in the angular position of a component relative to an axis, such as in response to the slope of a surface on which a wheel is supported, to engage and disengage alternately a one-way drive connection between a non-rotating component and a component that rotates with the wheel. The wheel is prevented from rolling backward on an inclined surface due to this engagement and is free to ascend the inclined surface due to the disengagement.
