A clutch apparatus may include a first shaft member having a first end portion including axially extending first protrusions. The clutch apparatus may also include a second shaft member arranged axially opposite the first shaft member, the second shaft member having a second end portion including axially extending second protrusions. Additionally, the clutch apparatus may include a clutch member having a disk-shaped main body arranged between the first shaft member and the second shaft member, the clutch member including an annular rim that encircles the main body and protrudes beyond the the main body in both axial directions, the annular rim including first recesses disposed on a first side of the clutch member and second recesses disposed on a second side of the clutch member. The second end portion may further include at least one latching element and the clutch member may further include at least one mating latching element.

Clutch apparatus and flap device for a fresh-air system having a clutch apparatus

An internal combustion engine may include at least one engine block having a plurality of cylinders and at least one flange component. At least one attachment part may be secured to the at least one flange component. An alignment device may be constructed and arranged to align the at least one attachment part relative to the at least one flange component when the at least one attachment part is attached to the at least one flange component. The alignment device may include at least a first alignment unit, a second alignment unit, and a third alignment unit, which may be spaced apart from one another. At least one of the first alignment unit, the second alignment unit, and the third alignment unit may be constructed and arranged to align the at least one attachment part to a cylinder head in relation to a first aligning direction perpendicular to an attaching direction, when the at least one attachment part is attached to the cylinder head. At least one of the first alignment unit, the second alignment unit, and the third alignment unit may be constructed and arranged to align the at least one attachment part to the cylinder head in relation to a second aligning direction perpendicular to the attaching direction and inclined to the first aligning direction. The at least first alignment unit, the second alignment unit, and the third alignment unit may each be constructed and arranged to align the at least one attachment part to the cylinder head exclusively in one of the first aligning direction or the second aligning direction.

Internal combustion engine comprising attachment part

An intake module of a fresh air system for an internal combustion engine may include a housing having a plurality of openings through which fresh air is flowable, and a control device for controlling a cross-section of at least one of the openings. The control device may include at least one control staff and at least one control valve arranged on the control shaft in a rotationally fixed manner for the at least one opening. The control shaft may be mounted on the housing by at least one bearing bracket such that the control shaft is rotatable about a rotational axis. The housing may have at least one bearing receiving portion for receiving the bearing bracket. The bearing receiving portion may have an insertion opening through which the bearing bracket may be inserted in an insertion direction oriented perpendicular to the rotational axis. The bearing bracket may have two outer surfaces facing away from one another in a transverse direction running perpendicular to the rotational axis and to the insertion direction. On each outer surface, the bearing bracket may have at least two positioning blocks projecting therefrom and spaced apart from one another in the insertion direction. The bearing receiving portion may have a guide contour for each positioning block for aligning the bearing bracket in a longitudinal direction running parallel to the rotational axis, and in the transverse direction.

Intake module of a fresh air system

An intake module of a fresh air system for an internal combustion engine may include a housing having openings through which fresh air is flowable, and a control device for controlling a cross-section of the openings. The control device may include at least one control staff rotationally mounted about an axis rotation on the housing by at least one bearing bracket, and at least one control valve rotationally fixed on the control shaft for at least one of the openings. The housing may have at least one bearing receiving portion having an insertion opening through which the bearing bracket may be inserted in an insertion direction oriented perpendicularly to the axis of rotation. The bearing bracket may have a first bearing part having a first bearing section on which the control shaft rests with a circumferential section, and a second bearing part having a second bearing section opposite the first bearing section on which the control shaft rests with a second circumferential section opposite the first circumferential section. The bearing parts may each have an inner surface facing one another in a transverse direction perpendicular to the axis of rotation and insertion direction, and at least one flat positioning surface extending perpendicularly to the transverse direction and raised from the inner surface. The positioning surfaces of the first and second bearing parts may rest flat against each other, and a gap may be formed in the transverse direction between the inner surfaces outside the positioning surfaces.

An internal combustion engine may include a cylinder head having a plurality of intake channels which lead to combustion chambers. A fresh gas distributor may be included for feeding fresh gas to the intake channels. The fresh gas distributor may have a flap arrangement including a flap shaft, which bears at least one flap for controlling the intake channels. The flap shaft may be mounted such that the flap rotates about a flap rotation axis. The fresh gas distributor may have a housing flange securing the fresh gas distributor to the cylinder head. The flap arrangement may be arranged in a region of the housing flange in a distributor housing of the fresh gas distributor. The cylinder head may have a recess, into which the fresh gas distributor is inserted in a region of the flap arrangement.
