In internal combustion engines, camshaft adjusting devices are used to adjust a phasing of a camshaft relative to a phasing of a crankshaft to thereby vary the opening and closing timing of the gas exchange valves. In vehicles with internal combustion engine, different types of camshaft adjusters can be used, for example camshaft adjusters with hydraulic or electrical control. The electric camshaft adjuster allows high adjustment speeds almost independent of engine speed and engine oil temperature.

Claims (7)

A variable speed gearbox for a vehicle, comprising an outer rotor (2), said outer rotor (2) defining a major axis (H), said outer rotor (2) having at least one abutment contour (6), said abutment contour (6) comprising first and second Stop surface (6a, b), with an inner rotor (3), wherein the inner rotor (3) relative to the outer rotor (2) in the circumferential direction with respect to the main axis (H) is rotatable, wherein the inner rotor (3) has a first and a second contact surface (7a, b), wherein the abutment contour (6) between the two contact surfaces (7a, b) is arranged, so that an end stop in the circumferential direction for the inner rotor (3) is formed, with a laying element (4) the inlay element (4) has a first abutment section (8a) for influencing a stop behavior of the end stop, wherein the first abutment section (8a) is arranged between the first stop face (6a) and the first contact face (7a), characterized h, at least one Ersatzeinlegelement (4a) for replacement of the insertion element, wherein the Ersatzeinlegelement (4a) having a first contact portion (8a), wherein the first contact portion (8a) of Ersatzeinlegelements (4a) has a different wall thickness than the first contact portion (8a) of the insertion element (4), so that the stop behavior of the end stop is formed differently in the insert element (4) and the replacement insert element (4a). Variable transmission device (1) according to Claim 1 , characterized in that the inlay element (4) has a second abutment section (8b), wherein the second abutment section (8b) of the inlay element (4) is arranged between the second abutment surface (6b) and the second contact surface (7b), and in that Replacement insert (4a) has a second contact portion (8b), wherein the second abutment portion (8b) of the replacement insert (4a) between the second stop surface (6b) and the second contact surface (7b) can be arranged. Variable transmission device (1) according to Claim 2 , characterized in that the second abutment section (8b) of the replacement insert (4a) has a different wall thickness than the first and / or second abutment section (8a, b) of the insert element (4). Variable transmission device (1) according to one of the preceding Claims 2 or 3 , characterized in that the first and second abutment sections (8a, b) of the inlay element (4) and / or replacement inlay element (4a) are connected in the direction of rotation by a connecting section (9), the first and second abutment sections (8a, b) of the Inserting elements (4) and / or substitute inlay elements (4a) together with the connecting portion (9) form a U-shaped cross section, wherein the connecting portion (9) a base leg and the two abutment portions (8a, b) each form a side legs. Variable-speed gear device (1) according to one of the preceding claims, characterized in that the wall thickness of the first abutment portion (8a) of the replacement insert (4a) is formed such that the first abutment portion (8a) on the first abutment surface (6a) and the first Contacting surface (7a), and in that the wall thickness of the second abutment portion (8b) of the replacement inserting member (4a) is formed such that the second abutment portion (8b) abuts the second abutment surface (6b) and the second contact surface (7b), and thus the first and / or second abutment section (8a, b) blocks a rotation of the inner rotor (3) relative to the outer rotor (2). Adjusting gear device (1) according to one of the preceding claims, characterized in that the insert element (4) and / or replacement insert element (4a) through the first and / or the second abutment portion (8a, b) in the direction of rotation and by the connecting portion (9) in axial and / or radial direction with respect to the main axis (H) is secured. Vehicle with the Verstellgetriebevorrichtung (1) for changing the compression ratio of a reciprocating engine or for changing a phase angle between a camshaft and a crankshaft, wherein the Verstellgetriebevorrichtung (1) according to one of the preceding claims.
