Embodiment Construction

[0036] In the following, reference will be made to Figure 1 to Figure 8 Embodiments according to the present disclosure are explained.

[0037] [Schematic Configuration of Valve Timing Control Device]

[0038] figure 1 A cross section of the valve timing control device 100 according to this embodiment is shown. Figure 5 An exploded perspective view of the valve timing control device 100 is shown.

[0039] Such as figure 1 As shown, the valve timing control device 100 includes a driving side rotary body A configured to rotate around a rotation axis X in synchronization with a crankshaft 1 of an engine E serving as an internal combustion engine; A member 20 (an example of a first gear) that is provided radially inside the drive side rotary body A and is configured to be integrated with a valve opening and closing intake camshaft 2 (an example of a camshaft) of the engine E centering on the rotary axis X and a phase adjustment mechanism C configured to set the relative rot...

Abstract

A phase adjustment mechanism for setting a relative rotational phase of a driven-side rotational body (B) to a drive-side rotational body (A) of a valve timing control device includes an output gear (25) around a rotational axis (X), an input gear (30) being rotated around an eccentric axis (Y), and an eccentric member (26). The eccentric member includes an outer peripheral surface with a first arc portion (51), a second arc portion (52), a plate spring (27) fitted between the first arc portion and the second arc portion, and a spaced portion (53). Each of the first arc portion and the secondarc portion is disposed from a position less than 90 degrees to a position more than 90 degrees as a central angle with respect to the eccentric axis from a biasing direction of the plate spring in the peripheral direction.

Description

technical field [0001] The present disclosure generally relates to a valve timing control device. Background technique [0002] There is known a valve timing control device that includes a driving-side rotating body configured to rotate synchronously with a crankshaft of an internal combustion engine around a rotating shaft, a driven-side rotating body, and a phase adjustment mechanism, and a driven-side rotating body that rotates The body is configured to rotate coaxially with the rotating shaft and rotate integrally with the valve opening and closing camshaft of the internal combustion engine, and the phase adjustment mechanism is configured to set the driven side rotating body relative to the driving side by the driving force of the electric actuator. The relative rotational phase of the rotating body. It is desirable to reduce noise in this type of valve timing control device (see, for example, JP2018-044501A (Reference 1)). [0003] In the valve timing control device ...
