Abstract
The invention discloses a phase regulator of a variable camshaft of an engine, which solves the problems that a function of the phase regulator fails and the service life is shortened and the like due to the fact that the gap between a stator and a rotor becomes larger because the condition that serious friction occurs between the stator and the rotor of the phase regulator exists in the phase regulator of the variable camshaft of the engine in the prior art, wherein the phase regulator is provided with a return function. The phase regulator of the variable camshaft of the engine comprises the stator, the rotor and a return spring, wherein the rotor is sleeved outside the stator; the return spring is arranged between the rotor and the stator; the return spring is formed by two alternately and parallel arranged torsional springs or more than two alternately and parallel arranged torsional springs of which the diameters are the same; the upper end of the return spring is an axial end and is connected with the rotor; and the lower end of the return spring is an radial end and is connected with the rotor. The phase regulator of the variable camshaft of the engine has the beneficial effects that the friction between the rotor and the stator of the phase regulator of the variable camshaft of the engine can be reduced, the reliability can be effectively improved, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of engine camshaft phase regulation technology, specially refer to a kind of variable camshaft phase regulator of engine.
Background technique
Variable camshaft phase regulator of engine (being also referred to as phase shifter or VCP) is the indispensable final controlling element that motor car engine realizes Variable Valve Time VVT function, its function is the order by electronic control unit ECU, realizes that camshaft produces certain phase place change with respect to bent axle.Because there are resistance in camshaft and driving mechanism thereof when operation, need external torque (generally being realized by return spring) to help camshaft to realize return.Prior art is taken back the variable cam phase regulator of bit function under the pressure of the restriction of installing space etc., generally only adopt a return spring as the outputting power source of external torque, for guaranteeing necessary return moment of torsion (being substantially equal to camshaft running resistance square), it is larger that return spring need be done, like this, single return spring has produced a larger moment of flexure in variable cam phase regulator inside when guaranteeing necessary return moment of torsion, may make between phase shifter stator and rotor heavy wear occurs, so that rotor and stator gap become large, cause phase shifter disabler and working life to shorten.Obviously, the variable cam phase regulator that prior art is taken back bit function exists may make between phase shifter stator and rotor heavy wear occurs, so that rotor and stator gap become large, causes the problems such as phase shifter disabler and working life shortening.
Summary of the invention
Heavy wear occurs in may the making between phase shifter stator and rotor of variable cam phase regulator existence of taking back bit function for solving prior art, so that rotor and stator gap become large, cause the problems such as phase shifter disabler and working life shortening, the present invention proposes a kind of variable camshaft phase regulator of engine.Variable camshaft phase regulator of engine of the present invention comprises stator, rotor and return spring, rotor is sleeved on the stator outside, return spring is arranged between rotor and the stator, described return spring is comprised of two or the identical alternately torsion springs of parallel arranged of two above diameters, its upper tip is axial termination and is connected with rotor, and lower end is connected for termination radially and with stator.
Further, the diameter of variable camshaft phase regulator of engine torsion spring of the present invention is less than stator outer diameter.
Further, the corresponding through hole that arranges on the upper tip of the variable camshaft phase regulator of engine torsion spring of the present invention insertion rotor is connected with rotor.
Further, the lower end card of variable camshaft phase regulator of engine torsion spring of the present invention leans against on the pin of stator faces and is connected with stator.
Further, the upper and lower termination of variable camshaft phase regulator of engine torsion spring of the present invention is all take the spring radius as the setting of axis vertical symmetry.
The useful technique effect of variable camshaft phase regulator of engine of the present invention is the friction that reduces between variable cam phase regulator rotor and the stator, its reliability of Effective Raise, increases the service life.

Embodiment
Accompanying drawing 1 is the front elevational schematic of variable camshaft phase regulator of engine of the present invention.Accompanying drawing 2 is A-A cross-sectional schematic of variable camshaft phase regulator of engine of the present invention, accompanying drawing 3 is the local enlarged diagrams of the I in the accompanying drawing 2, accompanying drawing 4 is schematic three dimensional views of variable camshaft phase regulator of engine return spring of the present invention, and among the figure, 1 is rotor, 2 is stator, 3 is that torsion spring I, 4 is the torsion spring II, and 3A is the upper tip of torsion spring I, and 3B is the lower end of torsion spring I, 4A is the upper tip of torsion spring II, and 4B is the lower end of torsion spring II.As seen from the figure, the present invention proposes a kind of variable camshaft phase regulator of engine.Variable camshaft phase regulator of engine of the present invention comprises stator 2, rotor 1 and return spring, rotor 1 is sleeved on stator 2 outsides, return spring is arranged between rotor 1 and the stator 2, described return spring is by two or two identical alternately torsion springs (3 of parallel arranged of above diameter, 4) form, its upper tip (3A, 4A) is axial termination and is connected with rotor 1, lower end (3B, 4B) is connected for termination radially and with stator 2.For easy for installation, simple in structure, the diameter of variable camshaft phase regulator of engine return spring of the present invention is less than stator outer diameter, and the corresponding through hole that arranges on the upper tip of the torsion spring insertion rotor is connected with rotor.The lower end card of torsion spring leans against on the pin of stator faces and is connected with stator.For guaranteeing equalising torque, axially do not producing friction, the upper and lower termination of variable camshaft phase regulator of engine torsion spring of the present invention is all take the spring radius as the setting of axis vertical symmetry.
Variable camshaft phase regulator of engine of the present invention adopts the torsion spring of the identical alternately parallel arranged of diameter as return spring, when the needs return, two torsion springs produce torsional moment and moment of flexure to rotor simultaneously, and, the torsional moment of two torsion spring generations is in the same way, because the upper and lower termination of variable camshaft phase regulator of engine torsion spring of the present invention is all take the spring radius as the setting of axis vertical symmetry, the rotor Moment is uniformly at circumference, can not produce deflection.And the moment of flexure of two torsion spring generations is reverse, just in time cancels out each other.Therefore, do not have pressure between rotor and the stator, can not produce axial rub yet, thus increase the variable cam phase regulator working life, improve its reliability.Because variable camshaft phase regulator of engine of the present invention does not need prior art variable cam phase regulator is done larger change and simple in structure, therefore, cost is lower, and production, installation and use are comparatively convenient, practical.
Obviously, the useful technique effect of variable camshaft phase regulator of engine of the present invention is the friction that reduces between variable cam phase regulator rotor and the stator, its reliability of Effective Raise, increases the service life.
