CHAIN GUIDING ELEMENT FOR A TIMING CHAIN, TIMING CHAIN DRIVE, AND VEHICLE ENGINE
A chain guiding element ( 1 ) for a timing chain ( 7 ) of a timing chain drive, with the guiding element having a rigid base body ( 3 ) is provided. A spring element ( 4 ) is arranged on the base body ( 3 ). The side of the spring element ( 4 ) facing the control chain has a guiding surface ( 6 ) for the timing chain ( 7 ), and a space is created between the base body ( 3 ) and the side of the spring element opposite the guiding surface ( 6 ).
1 . Chain-guiding element for a timing chain of a timing-chain drive, comprising a rigid base body, a spring element on the base body with a guiding surface for the timing chain on a side facing the timing chain and a spacing between the spring element and the base body on a side facing away from the guiding surface.
2 . Chain-guiding element according to claim 1 , wherein the base body and the spring element are formed as an integral component.
3 . Chain-guiding element according to claim 2 , wherein an opening forms the spacing between the base body and the spring element.
4 . Chain-guiding element according to claim 3 , wherein the guiding surface has a concave curvature.
5 . Chain-guiding element according to claim 3 , wherein the opening has a concave curvature.
6 . Chain-guiding element according to claim 1 , further comprising a damping mass at least partially filling the opening.
7 . Timing-chain drive for a vehicle engine, comprising a chain-guiding element with a rigid base body, a spring element on the base body with a guiding surface for the timing chain on a side facing the timing chain and a spacing between the spring element and the base body on a side facing away from the guiding surface.
