Abstract
A slide rail for damping a first side of a belt device of a belt drive includes an outer slide surface, an inner slide surface, an axial web, and a support-receiving element. The inner slide surface is oriented parallel to, and away from, the outer slide surface, and includes a rear side. The axial web has an axial extension disposed on the rear side. The support-receiving element is designed to orient the outer slide surface and the inner slide surface to damp the first side. In an example embodiment, the slide rail includes a transverse rib connecting the inner slide surface to the axial web.
Claims17
A slide rail for damping a first side of a belt means of a belt drive, comprising:
- an outer slide surface;
- an inner slide surface oriented parallel to, and away from, the outer slide surface, the inner slide surface comprising:
- an axial width;
- a rear side;
- and
- an overall extension in a running direction of the belt means;
- a stiffening device disposed on the rear side for stiffening the inner slide surface, the stiffening device comprising:
- a 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
- an axial web with an axial extension, the axial web 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 support-receiving element designed to orient the outer slide surface and the inner slide surface to damp the first side.
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.
