Embodiments of the invention are illustrated in the accompanying drawing with being simplified and are described in greater detail in the following description.
First view of the control gear of the rotational angle that Fig. 1 has schematically shown is of the present invention, be used for the adjustment cam axle,
Fig. 2 represents its second view, and
A side view of Fig. 3 control gear of the present invention.
Embodiment
First view of the control gear of the rotational angle that Fig. 1 has schematically shown is of the present invention, be used for the adjustment cam axle.
The rotational angle that this control gear is used for relative bent axle is regulated the rotational angle of at least one camshaft changeably.
The bent axle 1 of an internal-combustion engine drives one or more camshafts 3 by an elementary drive part 2, and this elementary drive part for example is constituted as a chain, toothed belt or series of gears.For this has disposed an actuation gear 4 to each camshaft 3, this actuation gear for example also can constitute belt wheel or sprocket wheel according to elementary drive part 2 and reach by elementary drive part 2 and bent axle 1 collaborative work.For example usually on a four stroke engine this actuation gear 4 implemented like this, promptly between bent axle 1 and camshaft 3, obtain two-to-one velocity ratio.In this way, the rotating speed of camshaft 3 is designed to half of rotating speed of bent axle 1.
Internal-combustion engine has suction valve and outlet valve 5, and they are opened by the cam 8 of at least one camshaft 3 and be closed, and described cam has the cam working face that relative camshaft 3 constitutes prejudicially.Can be like this, promptly suction valve and outlet valve 5 by a common camshaft 3 operation or suction valve 5 is operated by admission cam shaft 3 and outlet valve 5 dividually by exhaust cam shaft 3 operations.Suction valve and outlet valve 5 are also referred to as scavenging air valve (Gaswechselventile), and they are respectively pressed to the direction of a valve seat 10 by a valve spring 9.Suction valve and outlet valve 5 each contact are on its valve seat 10 in the state of closure.
Described cam 8 has and has cross section first cam working face and second cam working face, a general triangular.First cam working face of the rising of cam 8 acts on corresponding suction valve and the outlet valve 5 by a mechanical part and the spring force of the valve spring 9 that opposing is disposed makes these valves 10 opens on the direction and move of lifting off a seat.When second cam working face of the decline of cam 8 these valve springs 9 make corresponding suction valve and outlet valve 5 again return movement to affiliated valve seat 10.
Adjustment by camshaft 3 relative bent axles 1 can make what is called ventilation (Ladungswechsel) working state of adaptive internal-combustion engine best in the firing chamber.The so-called valve control time i.e. the moment that opens or closes of suction valve and outlet valve 5, is not provided by bent axle 1 regularly, but can regulate changeably by adjusting camshaft 3.Adjustment by camshaft 3 will mainly reach the power higher than the internal-combustion engine that uses the standing valve control time, low discharge of poisonous waste and low fuel consumption.
According to the present invention, between actuation gear 4 and camshaft 3, be provided with a phase adjusting device of mechanically working basically 11, but very worthwhile the reaching simply of this phase adjusting device cost constitutes.
Camshaft 3 of the present invention has a shaft shoulder 35, and this shaft shoulder is rotatably supported in the bearing 36 of actuation gear 4.The axis 37 of these bearing 36 relative camshafts does not upwards have degrees of freedom in axial and footpath thus at the shaft shoulder 35 of the stationary cam axle 3 that axially and directly makes progress.
The shaft shoulder 35 of camshaft 3 is arranged on the end face side towards camshaft 3 that for example the end face side and the bearing 36 towards actuation gear 4 of camshaft 3 are arranged on actuation gear 4.
Bearing 36 for example is constituted as an annular sleeve, and it is surrounding on the circumference at least segments in a circular shape and is for example radially acting on the shaft shoulder 35 on the both sides with extending.This annular sleeve for example also can be interruption from circumference, so that constitutes a plurality of part annular sleeves on the circumference of the shaft shoulder 35.For example four part annular sleeves are configured to bearing 36.
The shaft shoulder 35 is separated with distance with this actuation gear in the axial direction with actuation gear 4 adjacent reaching, so that reduce the friction of bearing 36.
According to the present invention, camshaft 3 and actuation gear 4 mechanically connect each other by at least one hinge joining means 38.
Each hinge joining means 38 has two for example arms 40 of straight line, and they are connected to each other by a middle hinge 39 and accompany angle each other or be arranged forming V-shape.For example be provided with two hinge joining means 38.Each hinge joining means 38 for example hingedly is connected on the bearing 36 of actuation gear 4 with an one arm 40 and hingedly is connected on the shaft shoulder 35 of camshaft 3 with its another arm 40.The axis 37 of the relative camshaft in end that deviates from middle hinge 39 of these arms 40 is arranged on the shaft shoulder 35 or on the bearing 36 separately prejudicially.These arms 40 of hinge joining means 38 can be supported around unique spin axis rotationally in the end that it deviates from middle hinge 39 respectively, and this spin axis extends perpendicular to the drawing ground of Fig. 1.Middle hinge 39 has the unique spin axis perpendicular to the drawing setting of Fig. 1 equally.The length of these arms 40 of hinge joining means 38 is designed in this wise, so that the middle hinge 39 relative arms 40 of hinge joining means 38 are always given prominence on the direction of leaving actuation gear 4.
For example relatively rotating between camshaft 3 and the actuation gear 4 produces by an actuator 21, and this actuator for example is configured as motor and is fixed on the internal-combustion engine.This actuator 21 for example acts synergistically with an axially movable dish 42.
The for example relative camshaft 3 of described dish 42 is provided with one heart and passes dish hole 46 by camshaft 3.Dish 42 contacts on the middle hinge 39 of hinge joining means 38 loosely, so that the torque of actuation gear 4 can not be delivered on the dish 42 and dish 42 can and then not rotate by bearing 36, hinge joining means 38 and middle hinge 39.Hinge joining means 38 for example is pressed on the dish 42 by a Returnning spring 47 with middle hinge 39.Returnning spring 47 for example is set between the shaft shoulder 35 and the middle hinge 39, it be supported on the shaft shoulder 35 and leave the shaft shoulder 35 axially on act on the middle hinge 39.
A leading screw 43 and a threaded sections 44 that is located on the dish 42 that is for example driven rotatably by actuator 21 interacts, and this threaded sections for example is formed in the hollow cylinder sleeve 45 and has internal thread.Described sleeve 45 stretches out from coiling 42 on the direction of camshaft 3 in the side towards actuator 21.
The interaction of the screw thread by leading screw 43 and the internal thread of threaded sections 44 has produced coils 42 translational motion.Therefore actuator 21 makes dish 42 move in the axial direction and an axial pressure is acted on described at least one middle hinge 39 in this way, the axis 37 of this axial pressure by a relative camshaft of corresponding lever arm, so that forms between camshaft 3 and actuation gear 4 and relatively rotates on camshaft 3 as torque.According to the sense of rotation of the leading screw 43 that is driven by actuator 21, dish 42 is towards actuation gear 4 or leave this actuation gear ground motion.
Distance between the end that deviates from middle hinge 39 of arm 40 is directly determined the angular displacement of camshaft 3 relative actuation gears 4 and bent axle 1.
Towards actuation gear 4 motions (Fig. 2), then this dish is being pressed each middle hinge 39 with axial force towards the direction of actuation gear 4 as fruit tray 42.If this axial force is enough big, described middle hinge 39 will be towards the motion of the direction of actuation gear 4, so that each arm 40 further struts each other, is increased by the distance between the end that deviates from middle hinge 39 of the angle of these arm 40 clampings and these arms 40.In this way, camshaft 3 is regulated (Fig. 3) backward against the sense of rotation rotation and the relative thus bent axle 1 of bent axle 1.
On the contrary, leave the motion of actuation gear 4 ground as fruit tray 42, then Returnning spring 47 is being pressed middle hinge 39 on dish 42 direction, so that the distance between the end that deviates from middle hinge 39 by angle and these arms 40 of these arm 40 clampings is dwindled and middle hinge 39 is and then coiled 42 motions.In this way, camshaft 3 on the sense of rotation of bent axle 1, rotate and thus relatively bent axle 1 regulate forward.
The torque of bent axle 1 is delivered to actuation gear 4 by elementary drive part 2 and bearing 36, hinge joining means 38 and the shaft shoulder 35 by actuation gear 4 are delivered on the camshaft 3.
When actuator 21 was switched off, camshaft 3 was connected with actuation gear 4 and bent axle 1 nothing with relatively rotating, has avoided the adjusting that is not intended to camshaft 3 thus.
Phase adjusting device 11 is made of the shaft shoulder 35 of camshaft 3, bearing 36, hinge joining means 38, dish 42 and the actuator 21 of actuation gear 4.
A first sensor 25 for example is set on camshaft 3, and it detects the rotational angle at that time of camshaft 3 and is sent on the electric control device 28 by first signal conductor 27.And for example be provided with one second sensor 32 on bent axle 1, it detects the rotational angle at that time of bent axle 1 and is sent to control gear 28 by secondary signal lead 33.Can try to achieve the deviation angle of camshaft 3 relative bent axles 1 by the first sensor 25 and the comparison of the signal of second sensor 32.
When camshaft 3 need be conditioned, actuator 21 is connected by pilot 29.
For example relatively rotating of camshaft 3 relative actuation gears 4 is limited on the predetermined regulation range by machinery or electronic section, to prevent the collision of suction valve and outlet valve 5 and internal combustion engine.
