- the present invention relates to a first rotating body that rotates together with a camshaft of an internal combustion engine, a second rotating body that rotates together with a crankshaft of the internal combustion engine and that can rotate relative to the first rotating body, Control means for changing the relative rotational phase between the first rotating body and the second rotating body, and a twisted coil panel that biases the first rotating body in a direction to advance with respect to the second rotating body.
- the present invention relates to an open / close valve timing control device.
- Another object of providing a torsion coil panel is related to starting an internal combustion engine.
- the starting is often performed by locking the first rotating body and the second rotating body in a predetermined phase state by hydraulic pressure.
- the first rotating body easily reciprocates with respect to the second rotating body for which the supply of oil for phase control is insufficient at the time of starting, it may be difficult to lock.
- the first rotating body does not advance due to the resistance applied to the cam shaft, and cannot be locked quickly. For this reason, a torsion coil panel is provided to constitute a device that can quickly perform the locking operation.
- Patent Document 1 As this type of valve opening / closing timing control device, there is Patent Document 1 shown below as prior art document information relating to the present invention.
- a gap is provided between the coil panel portion of the torsion coil panel and each peripheral surface of the first rotating body or the second rotating body.
- Patent Document 1 Japanese Patent Laid-Open No. 2002-27612 (paragraph numbers 0014, 0032, FIG. 1) Disclosure of the Invention
- the torsion coil panel has its first and second shafts based on the relative rotation between the first rotating body and the second rotating body. If the deformation is caused to incline with respect to the axis of the rotating body, the coil burner portion may still come into contact with the peripheral surface of the rotating body even if a gap is provided.
- the coil panel part is formed in a cylindrical shape with a constant winding diameter over the entire length. Therefore, it was predicted which part of the coil panel part would be in contact with the peripheral surface of the rotating body 1, for example, the vicinity of the center part of the coil panel part would be in contact with the rotating body. In this case, since the amount of relative movement with respect to the rotating body is larger in the vicinity of the center portion than in the other portions of the coil panel portion, once it comes into contact with the rotating body, it will greatly affect the appropriate control of the valve opening / closing timing.
- an object of the present invention is to generate excessive frictional resistance between the coil panel portion of the torsion coil panel and the rotating body.
- An object of the present invention is to provide a valve timing control device capable of avoiding that the panel power is not exerted.
- a first characteristic configuration of the present invention includes: a first rotating body that rotates together with a camshaft of an internal combustion engine; a rotary body that rotates together with a crankshaft of the internal combustion engine; A second rotating body rotatable relative to the first rotating body, a control means for changing a relative rotation phase of the first rotating body and the second rotating body, and the first rotating body with respect to the second rotating body.

And a torque generating region located between the pair of holding regions, and the holding region and the torque generating region are different from each other in diameter. .
- the torque generation region since the rolling diameters of the holding region and the torque generation region are different, the torque generation region always has a peripheral force of the rotating body to which the corresponding locking portion is locked. Distanced radially outward or radially inward. Therefore, even if a part of the torque generation region or the entire force ⁇ approaches the misaligned rotating body based on the diameter reduction of the coil portion based on the relative rotation between the first rotating body and the second rotating body.

As a result, the torque generation region is not affected by the peripheral force or frictional force of the first rotating body or the second rotating body, the desired panel force of the torsion coil spring is exhibited, and the valve opening / closing timing can be controlled well. .

- the holding region is a winding portion that is in close proximity to the locking portion.
- the amount of relative movement with respect to the locking portion or the rotating body is very small, and even if it contacts the rotating body, the effect is negligibly small.
- the torque generation region is located farther from the holding portion than the holding region, the amount of relative movement with respect to the locking portion or the rotating body is large when the torsional coil panel is torsionally deformed. Therefore, in order to exert the desired panel force of the twisted coil panel, which is greatly affected if it comes into contact with the rotating body, it is necessary to prevent contact with the rotating body.
- the pair of holding regions are in contact with the peripheral surfaces of the first rotating body and the second rotating body within a range of one turn from the locking portions. Accordingly, the coil portion is positioned with respect to the first rotating body and the second rotating body.
- the holding region contacts each circumferential surface of the rotating body, the coil portion can be more reliably positioned with respect to the rotating body. Also, the range of contact from the locking part Since it is within one turn, the contact portion does not affect the movement of the rotating body due to friction with the peripheral surface of the rotating body.
- a third characteristic configuration of the present invention is that among the windings forming the torque generation region, the windings adjacent to each other along the axial center direction of the torsion coil panel are the first rotating body and the first winding. The point is to maintain a non-contact state regardless of the relative positional relationship with the rolling element.
- one of the pair of locking portions of the torsion coil panel is disposed inside the torsion coil panel among the first rotating body and the second rotating body.
- the other of the pair of locking portions is locked to the inner peripheral surface of the rotating body, which is disposed outside the torsion coil panel, of the first rotating body and the second rotating body.
- the torque generation region has a larger diameter than the holding region connected to the one locking portion locked to the outer peripheral surface, and is locked to the inner peripheral surface. It has a smaller diameter than the holding region connected to the other locking portion.
- the torque generating region of the torsion coil panel has a larger diameter than the holding region connected to the locking portion locked to the outer peripheral surface of the rotating body. It is always spaced radially outward from the outer periphery.

Are separated. Therefore, based on the relative rotation between the first rotating body and the second rotating body, the torque generating area is always held even if it approaches a part of the torque generating area or the entire rotating body, or a rotating body that is displaced.
- a fifth characteristic configuration of the present invention is that the pair of locking portions of the torsion coil panel are both in front.
- the torque generating area is locked to the inner peripheral surfaces of the first rotating body and the second rotating body arranged outside the torsion coil panel, and the torque generation area is a pair of holding areas connected to the locking portions. However, it is smaller than the deviation and has a winding diameter.
- the pair of locking portions of the torsion coil panel are outer peripheral surfaces of the first rotating body and the second rotating body, both of which are disposed inside the torsion coil panel.
- the torque generation region is in a point having a winding diameter larger than a deviation of a pair of holding regions connected to the respective locking portions.
