Device for adjustment of basic position of camshaft adjustment accessory on internal combustion engine

摘要

Both component parts are rotatably adjustable between two end positions by a positioning piston. The camshaft adjustment device (1) on the free face side (3) of the component part (2) fixed to the camshaft has one or more forced locking and/or positively engaged force transmission components, on which during the adjustment process an auxiliary tool (8) with contour components (9,10) engages for turning the component part (2) fixed to the camshaft in relation to the component part (6) fixed to the crankshaft. The force transmission components on the camshaft adjustment device (1) are formed as two axial blind holes in the free face surface (3) of the camshaft component part (2) which are coaxial and displaced through 180 deg .
