BELT AND CHAIN DRIVE COMPRISING A TENSIONER AND A CLAMPING ELEMENT

摘要

The invention relates to a belt and chain drive comprising a hydraulic tensioner (1) that has a housing (2) which is made of a light metal alloy and in which a steel slide bush (4) is inserted. The slide bush (4) has an axially deployable piston to deflect a tensioning and guiding unit, such as a roller or a rail. A securing element (11) which prevents the slide bush (4) from leaving the housing is arranged in a clamping manner between the housing and the slide bush. The invention also relates to an internal combustion engine comprising such a belt and chain drive and a belt or chain that can be tensioned.
