Claim 10:
11. A belt drive assembly for a drive train comprising:
a drive input shaft with a first cone pulley pair;
a drive output shaft with a second cone pulley pair;
a chain or a belt connecting the first cone pulley pair to the second cone pulley pair for torque transmission;
a slide rail for damping a first side of the chain or the belt, the slide rail being arranged on the chain, the slide rail comprising:
a first rail half comprising:
a first outer slide surface arranged on an outer surface of the chain;
a first inner slide surface oriented parallel to, and away from, the first outer slide surface, arranged on an inner surface of the chain, and comprising:
an axial width;
a rear side; and
an overall extension in a running direction of the chain or the belt;

a stiffening device disposed on the rear side for stiffening the inner slide surface, the stiffening device comprising:
a first stiffening rib extending from the inner slide surface in a transverse direction over the overall extension, the stiffening rib having an axial width less than the inner slide surface axial width; and;
a first axial web arranged on a portion of the rear side, the first axial web comprising an axial extension delimiting the stiffening rib transversely on an inside and comprising a variable axial width that tapers to a reduced axial width towards an inlet side or an outlet side of the slide rail; and

a first support-receiving element arranged inside of the first inner slide surface, the first support-receiving element designed to orient the first outer slide surface and the first inner slide surface to damp the first side.
