Embodiment Construction

[0040] figure 1 A hydraulic camshaft adjuster 2 for adjusting the rotational angle of a camshaft 3 is shown in longitudinal section. according to figure 1 The section A-A of figure 2 shown in . The camshaft adjuster 2 includes an outer stator 4 in which an inner rotor 6 is pivotably arranged concentrically. The rotor 6 is connected to the camshaft 3 by means of a central screw 7 . Between the stator 4 and the rotor 6 is formed a chamber, not shown in detail here, which is closed axially by two side covers 8 a , 8 b and is delimited circumferentially by radial webs 9 of the stator 4 . The two side covers 8 a , 8 b are connected to the stator 4 in a rotationally fixed manner by means of screws 11 .

[0041] The rotor 6 comprises a central circular oil supply 12 (see figure 2 ) of the hub part 10. The oil supply 12 is arranged concentrically to the axis of rotation D of the rotor 6 . The central screw 7 is guided through the oil supply 12 . Hydraulic medium, in particu...

Abstract

A rotor for a camshaft phaser includes a hub part having an oil supply passage, at least one vane radially disposed on the hub part, as well as oil channels extending through the hub part and fluidically connected to the oil supply passage. The manufacture of the rotor is considerably simplified because the rotor is made up of a main body and at least one cover element arranged on an end face of the main body. The oil channels are axially closed by the cover element.

Description

technical field [0001] The invention relates to a rotor for a camshaft adjuster, comprising a hub part with an oil supply, at least one vane arranged radially on the hub part and extending through the hub part in relation to the oil supply. Flow-technically connected oil channels. The invention also relates to a camshaft adjuster for adjusting the rotational angle of a camshaft relative to a crankshaft of an engine, which camshaft adjuster has such a rotor. Background technique [0002] In internal combustion engines, especially in gasoline-powered motor vehicle engines, camshafts are used for actuating so-called gas exchange valves. The cams of the camshaft usually rest against cam followers, such as cup lifters, drag rods or rockers. If the camshaft is turned, the cam rolls on the cam follower, which in turn actuates the gas exchange valve. Therefore, through the position and shape of the cam, not only the opening duration and opening range of the ventilation valve are ...
