摘要： The invention proposes a connecting element (9) for retaining a lever-type cam follower (1), that serves to activate a gas exchange valve (5) of an internal combustion engine, inseparably on a support element (2) comprising a spherical end (7) on which the cam follower (1) is pivotally mounted through a concave depression (6). The connecting element (9) engages into an annular groove (8) under the spherical end (7). In a connecting element (9) of this type, a central portion (10) of the connecting element (9) bears against an underside (11) of the cam follower (1) oriented toward the support element (2) and forms, through two legs (12, 13) and a crossbar (14) connecting these legs (12, 13) to each other, a U-shaped recess (15) in longitudinal direction of the cam follower (1). This recess (15) engages around the groove (8) after the manner of a fork and orthogonally to a pivoting direction of the cam follower (1), substantially without lash. Angled retaining claws (16, 17) bent from the legs (12, 13) extend in transverse direction of the cam follower (1) and engage after the manner of pincers over side walls (18, 19) of the cam follower (1). By a clamping of the retaining claws (16, 17) through shaped sections (22, 23) directed toward inner surfaces (24, 25) of the side walls (18, 19), the U-shaped recess (15) is substantially fixed in respect of position in transverse direction of the cam follower (1) and in respect of shape.

摘要： Connecting element (10) retains cam follower (2), which actuates gas-exchange valve (4) of an internal combustion engine, on support element (6). Support element (6) has spherical end (7) on cylindrical section (22) and on which cam follower (2) is mounted, so as to be pivotably movable in the direction of gas-exchange valve (4) about center of rotation (9). Connecting element (10) has elastically deformable projections (21), which proceed from central webs (19), parallel to the pivot axis of cam follower (2) such that connecting element (10) is connected to cylindrical section (22) in a frictionally-engaging manner. Projections (21) are embodied as lugs (20) which angle away from central webs (19) and extend in a direction pointing away from cam follower (2), so that projections (21) are elastic in shape.

摘要： A connection element (9, 10) is provided for the captive mounting of a lever-type cam follower (1), which is used to actuate a gas-exchange valve (5) of an internal combustion engine, on a support element (2). The support element (2) has a spherical end (7) on which the cam follower (1) is pivotably mounted by a concave molding (6). The connection element (9, 10) is made from a flat material and is arranged, with a central section (11), on a bottom side (12) of a base (13) facing the support element (2). The base surrounds the concave molding (6) and connects to the side walls (27) of the cam follower (1). The central section forms, with two limbs (14) that are spaced apart from each other and a web (15) connected with the limbs, a U-shaped recess (16), which extends in a longitudinal direction of the cam follower (1) and which surrounds, in an essentially play-free manner, an annular groove (8) below the spherical end (7) in a fork-like manner and orthogonal to a pivoting direction of the cam follower (1). The limbs (14) transition into retaining grips (17) offset by approximately 90° and the web (15) transitions into a support wall (18) offset by approximately 90°. Retaining lugs (19, 20) located on the retaining grips and the support wall are engaged on a top side (21) of the base (13) facing away from the support element (2) for holding the connection element (9, 10) on the cam follower (1). The retaining grips (17) are supported on inner sides (26) of the side walls (27) of the cam follower (1) such that the U-shaped recess (16) is essentially fixed in position in a perpendicular direction relative to the cam follower (1) and in terms of a shape thereof.

摘要： A rocker arm or finger lever (1) formed without machining (by a non-cutting shaping process) which has a U-shaped profile in cross section over almost its entire length which is open toward the top or the bottom, whereby the rocker arm or finger lever (1), in its end region in which it contacts a valve shaft end, is constructed double-walled. This rocker arm or finger lever (1) is distinguished in that the double-walled section or at least a strap (13) projecting over the longitudinal extension of the rocker arm or finger lever (1) is formed on an upper wall (10) which is bent under and lies between its two side walls (11, 12). A lever configured in this manner can be manufactured economically and has a good rigidity despite the reduced material used.

摘要： Disclosed is a drag lever (1) comprising two side walls (2, 3) which are connected together by a transversal bar (4) which is arranged on an end (6) of the lower side (5) thereof on an end (6) thereof on a head of a support element (9) by means of a dome-shaped cavity (7) on a head (8) of a support element (9). A clamp (10) is applied to the end (6) thereof. The clamp fixes the drag lever (1) to the head such that it can be displaced in a pivoting direction thereof. The clamp (10) is made of thin-walled wire material and extends essentially in a transversal manner in relation to the longitudinal axis of the drag lever (1) and is arranged on the lower side (5) of the transversal bar (4) by means of a central section (11) which is formed by webs (12, 13) which extend in a semi-circular manner in a part of the support element (9) which has a reduced diameter (14) and is located below said head (8). The clamp (10) continues on each outer surface (15, 16) of a corresponding side wall (2, 3) by means of two parallel projections (17a, 17b, 18a, 18b) and the ends of said projections are snapped on an upper side (19, 20) of the respective side wall (2, 3) or on a bearing surface which is essentially parallel to the upper side (2, 3) such that at least more than half of the upper side (19, 20) or the bearing surface is covered.
