Embodiment Construction

[0013] figure 1 with figure 2 The drive wheel 1 according to the invention is shown in two successive assembled states. figure 2 The drive wheel 1 is shown with an inner wheel 2 designed as a hub, which is provided for mounting on a drive shaft (not shown here). The inner wheel 2 has a plurality of circumferentially spaced spokes 3 which extend radially outward. Furthermore, an outer wheel 4 corresponding to the inner wheel 2 has a plurality of circumferentially spaced projections 5 extending radially inwards between the spaced apart spokes 3 of the inner wheel 2 . Furthermore, the outer wheel 4 has a ring gear 6 formed on its outer circumference, into which a traction mechanism (not shown here) can engage. The spokes 3 of the inner wheel 2 extend as far as the inner circumference of the outer wheel 4 , so that recesses 12 are formed which are closed between the spokes 3 and the sides of the projections 5 . The drive wheel 1 has a form-fitting connection 8 according to...

Abstract

The wheel (1) has an inner wheel part (2) formed as a hub, and multiple arms (3) spaced in a circumferential direction and radial-outwardly extending corresponding to an outer wheel part (4). Multiple projections (5) are spaced in the circumferential direction, and radial-inwardly extend between the arms of the inner wheel part. A toothed ring (6) is formed at a peripheral surface. An elastomer (7) connects the outer- and inner wheel parts between side surfaces of the arms and the projections. A supplementary positive connecting device is formed between the outer- and inner wheel parts. The elastomer is a rubber composition, which is cohesively introduced into pockets (12) by a vulcanizing process.

Description

technical field [0001] The invention relates to a drive wheel for a traction element transmission, which has an inner wheel configured as a hub, an outer wheel corresponding to the inner wheel, and a ring gear configured on the outer peripheral surface of the outer wheel, wherein the inner wheel includes a plurality of Circumferentially spaced apart radially outwardly extending spokes, the outer wheel includes a plurality of circumferentially spaced apart radially inwardly extending bosses between the circumferentially spaced apart spokes of the inner wheel, wherein between the spokes and the bosses Between the sides, an elastomer connects the outer wheel to the inner wheel. Background technique [0002] Drive discs are used in transmissions that transmit force from a drive element (eg a crankshaft) to another element to be driven (eg a camshaft) via a traction mechanism. For this purpose, a drive disc is integrated in the transmission, which drive disc is connected to the ...
