    摘要: Continuously variable transmission includes a set of pulleys, each pulley comprising two discs arranged relatively axially moveable on a central pulley shaft for clamping a transmission belt. The belt includes a continuous array of transverse elements, each having lateral pulley contact surfaces for contacting the belt contact surface of each of the pulley discs, and being provided slideably on an endless tensile element of the belt. Each pulley has a mechanical stiffness as incorporated in the transmission and a stiffness related feature of a pulley when expressed as a parameter Sag that indicates an amount of radial displacement of the belt between the discs in the transmission, occurring in response to imposing a maximum amount of axial force Fax during operation of the transmission, relative to a radial position of the belt in an unloaded state of the transmission, amounts to less than 1.2 mm but more than 0.5 mm.

    摘要: The invention relates to a roller vane pump for operating an automatic transmission for motor vehicles. The pump is provided with a pump housing (12), a rotor (4), a cam ring (2) and roller elements (7), which define a number of pump chambers (13). Fluid is communicated between a hydraulic channel (24) and a pump chamber (13) through suction ports (11 and 16) and discharge ports (17 and 18). According to the invention the pump is provided with a suction port (26) for allowing a predominantly radial flow of fluid to a pump chamber (13) and/or with a rotor (4) with slots (6) with a circumference (32) which is partly curved with a curvature substantially matching the curvature of the roller elements (7) and/or with a rotor (4) with a circumference segment (30) deviating at least partly from a circle, in order to decrease the amount of wear of pump parts as well as the noise level generated during pumping.

    摘要: A transmission includes a set of pulleys, in which at least one disc is axially displaceable and provided with cylinder piston elements. The cylinder/piston elements include at least one pressure chamber with radial walls and concentric cylinder walls and at least one of the radial walls of the pressure chamber is secured to one of the concentric cylinder walls by an immovable fit. The wall near to the fit is produced with a resiliently hingeable feature, in which the hinging feature is realized with the inclusion of an axially extending sleeve like foot part, integral to the wall, and with both axial faces thereof extending uninterrupted smoothly up to the lower end part of the wall.
