Fig. 4 is shown between two natural frequencies the centrifugal pendulum mechanism of conversion automatically with exploded view Structural embodiment.
Detailed description of the invention
Fig. 1 is shown in automatic conversion between two natural frequencies when running with line length l completely Centrifugal pendulum mechanism 100.This centrifugal pendulum mechanism 100 is for being arranged in oil-engine driven motor vehicles In drivetrain.Centrifugal pendulum mechanism 100 is used for being arranged in torsional vibration damper, especially flying in double quality On wheel, especially on the output of torsional vibration damper.Centrifugal pendulum mechanism 100 is used for reducing internal combustion engine Periodically rotate inhomogeneities.Centrifugal force pendulum 100 is for having the internal combustion engine closed with cylinder Utilization.Internal combustion function is run with number of cylinders completely or with a small amount of number of cylinders.Such as, internal combustion Facility have four cylinders, can close two cylinders so that internal combustion function selectivity in these four cylinders Ground runs as four cylinder internal-combustion engines or as two cylinder internal-combustion engines.
Centrifugal pendulum mechanism 100 can be with the first natural frequency or with the second natural frequency operation.Centrifugal Power pendulum device 100 is transported with number of cylinders completely at internal combustion engine for reducing with the operation of the first natural frequency Whirling vibration during row.Centrifugal pendulum mechanism 100 is used for including reduction with the operation of the second natural frequency Whirling vibration when combustion engine is run with a small amount of cylinder.
Centrifugal pendulum mechanism 100 has the first pendulum mass 102, and this first pendulum mass is at centrifugal action Under can swing between the first terminal position and the second terminal position.Centrifugal pendulum mechanism 100 have turn Changing device 104.Conversion equipment 104 has ratchet 106, ratchet 108 and spring 110.Spring 110 In engagement side upwardly toward ratchet 108 loaded pawl 108.Centrifugal pendulum mechanism 100 has the second pendulum matter Amount 112, this second pendulum mass also can swing between the first terminal position and the second terminal position.Second Pendulum mass 112 is coordinated according to the second natural frequency.
When internal combustion engine runs with the cylinder that partially turns off, the internal combustion engine of such as four cylinders is with two gas Cylinder run time, the second pendulum mass 112 in its resonance range with the swing amplitude more than a predetermined value, The second pendulum mass 112 is made to arrive ratchet 108.In the terminal position of its ratchet side, pendulum mass 112 As clashed into towards ratchet 108 shown in left side view in FIG and making ratchet resist spring 110 Power unclamp with ratchet 106.During a hunting period, conversion equipment 104 is as existed in FIG So staying open shown in middle illustration, during i.e. ratchet 108 is engaged to ratchet 106 the most again. Before ratchet 108 is engaged to again in ratchet 106 in time, pendulum mass 112 is as in FIG on the right side Such shown in side diagram clashes into towards ratchet 108 the most again and prevents conversion equipment 104 from closing. Thus, first 102 are swung with the swing of line length l completely.
Centrifugal pendulum mechanism 100 when Fig. 2 is shown in line length l/x to shorten, such as l/2 runs. In the case of the power of spring 110 loads, ratchet 108 is engaged in ratchet 106.Internal combustion engine with When number of cylinders is run completely, the internal combustion engine of such as four cylinders is when running with four cylinders, the second pendulum matter Measure 112 outside its resonance range with the swing amplitude less than a predetermined value so that the second pendulum mass 112 Do not arrive ratchet 108 and the conversion equipment 104 that closes is not switched on.Therefore, the first pendulum mass 102 With the line length l/x vibration shortened.Second pendulum mass 112 is for according to frequency manipulation transforms device 104 And therefore can be referred to as sensor-pendulum mass.
Fig. 3 is shown between two natural frequencies that automatically change, such as being centrifuged according to Fig. 1 and Fig. 2 The structural embodiment of the such centrifugal pendulum mechanism of power pendulum device 100 200.Fig. 4 is to decompose Illustrate centrifugal pendulum mechanism 200.Centrifugal pendulum mechanism 200 has pendulum mass bearing part 202.Currently, The flange part of the output side of double mass flywheel is used as pendulum mass bearing part 202.Centrifugal pendulum mechanism 200 There is multiple first pendulum mass.Exemplarily explain with reference to the first pendulum mass 204.First pendulum matter Amount 204 can shift on pendulum mass bearing part 202 under centrifugal action between two terminal positions Ground is arranged.First pendulum mass 204 connect betwixt have middleware 206 in the case of can arrange with shifting On pendulum mass bearing part 202.Pendulum roller, it is used for making the first pendulum mass 204 to shift such as 208 It is arranged on pendulum mass bearing part 202.Centrifugal pendulum mechanism 200 has the conversion dress being not shown here Put.By means of this conversion equipment energy locking and/or release middleware 206 relative to pendulum mass bearing part 202 Can displaceability.When conversion equipment Guan Bi and middleware 206 are relative to pendulum mass bearing part 202 Can displaceability when being locked out, the displacement of the first pendulum mass 204 is carried out with the line length shortened.If turned Changing device open and middleware 206 relative to pendulum mass bearing part 202 can displaceability be released time, The displacement of the first pendulum mass 204 is carried out with line length completely.Sensor-the pendulum mass being not shown here For handling this conversion equipment.It addition, addedly, specifically referring to Fig. 1 and Fig. 2 and say accordingly Bright.
