Connection element for the captive mounting of a lever-like cam follower

Abstract

A connecting element (9, 10) for preventing loosening of a rod-shaped cam follower (1) for actuating a gas exchange valve ( 5). The support element has a spherical end (7) on which the cam follower (1) is rotatably mounted by means of a spherically segmented profile (6). In this case the connecting elements (9, 10) made of flat material rest via the central section (11) on the underside (12) of the base (13) facing the support element (2), which encloses the truncated spherical Shape (6) and connect the side wall (27) of cam follower (1) and constitute along the cam follower ( 1) A U-shaped groove (16) in the longitudinal direction, which fork-like surrounds the annular groove (8) below the spherical end (7) and surrounds the cam follower perpendicular to the cam follower substantially without play. said groove (8) in the direction of deflection of the element (1). In this case the legs (14) merge into the retaining pawl (17) at an angle of about 90° and the web (15) merges into the support wall (18) at an angle of about 90° . The retaining projections (19, 20) are locked on the upper face (21) of the base (13) facing away from the support element (2) in order to retain the connecting elements (9, 10) on the cam follower (1). In this case the retaining pawl (17) is supported on the inner side (26) of the side wall (27) of the cam follower (1) such that the U-shaped groove (16) is The lateral position of the movable member (1) and its shape are basically fixed.

Description

technical field [0001] The invention relates to a connecting element for securely holding a rod-shaped cam follower against loosening a support element with a spherical end for actuating a gas exchange valve of an internal combustion engine. The cam follower is rotatably mounted on the spherical end by means of a spherical shape. In this case, the connecting element made of flat material rests with a central section on the underside of the bottom facing the support element, which surrounds the spherical shape and connects the side walls of the cam follower. Together with the two spaced-apart legs and the web connecting the legs, the connecting element forms a longitudinal U-shaped groove of the cam follower, which fork-like surrounds an annular groove in the spherical end. Background technique [0002] As is known, such a connecting element can realize a generating unit which, for example, contains a pressure lever as a cam follower and a support element. Thus, with such a...

Consequently, the valve plunger is at risk for further or complete slippage from the support element, since the valve plunger is no longer sufficiently aligned on the cam when it comes into contact with its cam again due to the narrow cam contact surface.
