The invention is related to a toothed chain with alternating inner and outer chain links each joined by means of a chain joint, wherein the inner chain links comprise at least one inner plate and at least two joint bushes running perpendicularly through the same, the outer chain links comprise at least two outer plates and at least two joint pins running perpendicularly through the same, and to form a chain joint, one joint pin of the outer chain link each extends through a joint bush of the inner chain link, and at least one inner plate of the inner chain link and/or at least one outer plate of the outer chain link is embodied as a toothed plate with each two teeth defined by an outer flank and an inner flank each. To provide a toothed chain having an improved service life and which can lead to a more advantageous embodiment of the complete chain drive, it is provided that an external flank angle given for the two external flanks of a toothed plate, is &#x3b1;&#x2267;65&#xb0; and &#x2266;75&#xb0;, and a ratio Vbetween a pitch p of the toothed chain and the outer diameter dof the joint pins is &#x2266;2.65.

Toothed chain with optimized chain joint and enlarged external flank angle

The invention relates to a chain wheel (), especially for a timing chain drive, with a rotary shaft, a sprocket wheel () positioned around the rotary shaft featuring multiple alternating teeth () and tooth gaps () distributed around its circumference, as well as at least one chain guide (), the sprocket wheel () and the chain guide () are rigidly joined, the chain guide () incorporates a contoured surrounding support cage () causing it to bear on contact faces of link plates () and the support cage () or raised regions of the support cage () extend along a curved circumference that constitutes the perimeter of the chain guide (), said perimeter of the chain guide () having a non-circular profile.

Chain wheel and timing chain drive for the compensation of dynamic loads

A tensioner for endless driving elements, such as chains and belts, comprising a tensioning piston provided with locking means, and a locking piston which is adapted to be engaged with and disengaged from the locking means so as to arrest or release the movement of tensioning piston, the locking piston comprising an operating section causing locking piston to move to the arresting position and to the release position, and a locking area used for engagement with the locking means of the tensioning piston and arranged separately from the operating section.
