Document Type and Number:
Japanese Patent JP2007530850
Kind Code:
A
Abstract:
An electric camshaft adjuster for adjusting and fixing the phase angle of a camshaft of an internal combustion engine relative to a crankshaft thereof is provided. The camshaft adjuster is provided with a triple-shaft gear drive having a driving pinion that is fixed to the crankshaft, an output part which is fixed to the camshaft, and an adjusting shaft. The adjusting shaft is connected to a motor shaft ( 5, 5', 5'' ) of an electric adjusting motor that is provided as a pancake motor ( 1, 1', 1'', 1''' ) including a pancake ( 3, 3', 3'' ) and a stator ( 15, 15', 15'', 15''' ) which is disposed in a housing ( 8, 8', 8'' ) with an associated cover ( 9, 9', 9'' ). In order to create a camshaft adjuster that is inexpensive to produce and operate, the pancake motor ( 1, 1', 1'', 1''' ) is configured as a brushless DC motor (BLDC motor) whose housing ( 8, 8', 8'' ) and cover ( 9, 9', 9'' ) are arranged to be fixed to the cylinder head and whose motor shaft ( 5, 5', 5'' ) is connected to the adjusting shaft by a releasable coupling.
