Problems solved by technology

[0003] However, a disadvantage known from the prior art is that the adjusting actuator is mostly connected relatively rigidly to the camshaft adjuster, for example via a seal to the central valve.
In particular cases, when the internal combustion engine is subjected to extreme loads, it can even lead to damage to the connection of the adjusting actuator to the components fastened to the engine housing, since the components fastened to the engine housing are usually of very rigid design and cannot be easily retracted

Embodiment Construction

[0060] exist Figure 1 to Figure 16 There are different embodiments of the assembly 1 according to the invention, which can also be referred to as a camshaft adjustment assembly, a camshaft adjustment device or a camshaft adjustment system. In all these figures, the assembly 1 is shown in longitudinal section, wherein an axis of rotation 11 of the assembly lies in the cutting plane, about which the assembly rotates, at least in the operating state. The assembly 1 can be installed in the drive system of a motor vehicle (eg passenger car, van or bus) and can be connected to the camshaft 13 and the crankshaft of an internal combustion engine (eg gasoline or diesel engine). The assembly 1 comprises a camshaft adjuster 2 which is basically constructed and operated according to a camshaft adjuster / device (as it is known from WO 03 / 085238 A1) for varying the control timing of the gas exchange valves of an internal combustion engine . A camshaft adjuster 2 of the type according to t...

Abstract

The present invention relates to an assembly (1) with a vane-type camshaft adjuster (2) and an adjustment actuator (4). A centre valve (3) filled with a fluid for distributing the pressure, such as oil, is arranged in the vane-type camshaft adjuster. The adjustment actuator acts onto the center valve (3) through controlling the pressure fluid. The camshaft adjuster (2) is driven by dry a belt-type transmission element. The adjustment actuator (4) is arranged at a connection part (47) or is arranged on a component (22) fixed onto the shell of the internal combustion engine. Meanwhile, the adjustment actuator is connected with the component of the adjustment actuator through a connecting part (49). In the radial direction of the vane-type camshaft adjuster (2), the connecting part (49) swings to be discoupled to the component (22) fixed onto the shell of the internal combustion engine. The invention also relates to a driving system for vehicles.

Description

technical field [0001] The invention relates to an assembly with a vane camshaft adjuster and an adjusting actuator of the type, for example an electrically operable central magnet actuator, wherein a central valve distributing a pressurized fluid, such as oil, is present in the vane camshaft adjuster, the The control actuator acts on the central valve in a controlled manner for the distribution of pressurized fluid, wherein the camshaft adjuster is driven or can be driven by means of a dry-running traction drive, for example by means of a belt, wherein the control actuator is installed at the connection point Or can be installed on the component that is fixed on the housing of internal combustion engine and be in connection with the component of camshaft adjuster through coupling element; A dry-running traction drive, such as a belt drive, that drives the stator of a camshaft adjuster in the state, and has components fastened to the housing of the internal combustion engine, ...
