Describe according to the crank position control gear 100 of the motor of the embodiment of the present invention below with reference to Fig. 1-Figure 10.Wherein, motor comprises bent axle, body 200 and piston etc., and the working principle of motor etc., by those skilled in the art is known, are not just described in detail here.The rotation angle of the piston of general motor in atdc and bent axle is the oil spout igniting while spending of 90 degree to 105, and motor is the most easily lighted, the optimum igniting position that this position is motor.
According to the crank position control gear 100 of the motor of the embodiment of the present invention, as shown in Fig. 1-Figure 10, comprise: Flywheel disc 1, rocking arm 2 and actuating assembly 3, wherein, Flywheel disc 1 is suitable for being arranged on the bent axle of motor, the bent axle of motor can rotate by flywheel driven dish 1 while rotation, also can be with dynamic crankshaft to rotate when Flywheel disc 1 rotates simultaneously, and the periphery wall of Flywheel disc 1 is provided with mating groove 10.The first end of rocking arm 2 is suitable for being pivotably mounted on the body 200 of motor, particularly; the hinge axis 5 of the central axis of rocking arm 2 by being parallel to Flywheel disc 1 is located on body 200 pivotly; the second end of rocking arm 2 is provided with and coordinates tooth 20; rocking arm 2 is swingable between disengaging configuration and engagement positio around the first end of this rocking arm 2; wherein coordinate tooth 20 to be bonded in mating groove 10 at engagement positio, coordinates tooth 20 to depart from mating groove 10 at disengaging configuration.Particularly, coordinate the width of tooth 20 to be less than the width of mating groove 10.Actuating assembly 3 is connected to drive rocking arm 2 to swing with rocking arm 2.Wherein, be worth understanding, this actuating assembly 3 is electrically connected to drive the swing of rocking arm 2 according to the running state of motor with the control gear in automobile.
It will be appreciated that, in an embodiment of the present invention, Flywheel disc 1 should be made broad understanding, can be mounted in the existing Flywheel disc on the bent axle of motor, as described in Figure 1, the outer circumferential face of Flywheel disc 1 is provided with the gear teeth, and the gear teeth are for being connected with the starter motor of air motor.Alternatively, for example, do not arrange in the situation of starter motor, when each startup vehicle, the motor of automobile carries out ignition trigger by the in-cylinder injection air-fuel mixture gas in compression stroke to motor in the compressed tanks from other setting, and the periphery of Flywheel disc 1 be along also can having the gear teeth, can be also and the existing different discoid element of Flywheel disc on bent axle that is installed to, as long as the position of bent axle can be detected by it, thereby the residing stroke of each cylinder of motor detected.
Particularly, in the time of engagement positio, owing to coordinating tooth 20 to be bonded in mating groove 10, now Flywheel disc 1 stops operating, and then bent axle is stopped operating is that bent axle is positioned at stop position, and now crank position control gear 100 is in lockup state.In the time of disengaging configuration, owing to coordinating tooth 20 to depart from mating groove 10, now Flywheel disc 1 and bent axle are rotatable, and crank position control gear 100 is in released state.What deserves to be explained is, in the time that rocking arm 2 swings to engagement positio, the stop position of bent axle can be arranged so that the position of at least one piston in motor is in optimum igniting position.
In the time that engine ignition drives, actuating assembly 3 drives rocking arm 2 to swing to disengaging configuration and makes rocking arm 2 remain on disengaging configuration, now the cooperation tooth 20 on rocking arm 2 departs from mating groove 10 and does not affect the rotation of Flywheel disc 1, be that bent axle is free to rotate, now crank position control gear 100 is in released state.In the time that motor is about to shut down; the state of the rotating speed of Flywheel disc 1 in reducing gradually; be that Flywheel disc 1 can turn slower and slower; now actuating assembly 3 drives rocking arm 2 to swing to make the cooperation tooth 20 rocking arm 2 to contact with the periphery wall of Flywheel disc 1 from disengaging configuration to engagement positio, and crank position control gear 100 is in by lockup state.
When the mating groove 10 on Flywheel disc 1 is during through cooperation tooth 20 on rocking arms 2, rocking arm 2 is towards the central direction of Flywheel disc 1 segment distance that moves, the distance of motion is relevant with the cooperation stand out of tooth 20 and the rotating speed of Flywheel disc 1 with mating groove 10, because mating groove 10 is fixed value with the stand out that coordinates tooth 20, so the rotating speed of Flywheel disc 1 is higher, the distance that coordinates tooth 20 to move through mating groove 10 is shorter, otherwise, distance is longer, in other words, when Flywheel disc 1 highly rotates, coordinate tooth 20 cannot be bonded in mating groove 10, when the rotating speed of Flywheel disc 1 is during lower than critical speed of rotation, coordinate tooth 20 to be bonded in mating groove 10, be that crank position control gear 100 is in lockup state, Flywheel disc 1 is stopped operating by locking, thereby bent axle stops operating, make the position of at least one piston in motor in optimum igniting position, so that the igniting next time of motor.Wherein, what deserves to be explained is, critical speed of rotation refers to when coordinating tooth 20 can just be bonded on the rotating speed of the Flywheel disc 1 of mating groove 10 when interior in the time that Flywheel disc 1 rotates, in the present invention, can be by design mating groove 10 and the stand out that coordinates tooth 20, the critical speed of rotation of motor is designed into minimum, coordinates when reducing locking tooth 20 to join the impact of mating groove 10 when interior to.
According to the crank position control gear 100 of the motor of the embodiment of the present invention; can be in the time of engine shutdown; control the stop position of bent axle; to make at least one piston in optimum igniting position, ensure in the time of next engine start, can cross smooth oil spout and light a fire to promote engine start; thereby can cancel traditional cryogenic engine; reduced cost, and this crank position control gear 100 is simple in structure, makes easily.
According to some embodiments of the present invention, as shown in Figure 9, the sidewall of mating groove 10 is the parallel sidewalls of plane and mating groove 10 in passing through the center of Flywheel disc 1 and the line at mating groove 10 center.Thereby can be convenient to coordinate tooth 20 to be bonded in mating groove 10.Further, mating groove 10 is chamfered transition in the sense of rotation of Flywheel disc 1 between the sidewall of upstream and the periphery wall of Flywheel disc 1.Thereby at crank position control gear 100 when by lockup state, mating groove 10 on Flywheel disc 1 first contacts and coordinates a side of tooth 20 higher than opposite side, in the time that the distance that coordinates tooth 20 to move is longer than the height difference of mating groove 10 both sides, coordinate tooth 20 to be bonded in mating groove 10, now can be by the height difference of design mating groove 10 both sides, further the critical speed of rotation of motor is designed into lower, impact force while coordinating tooth 20 to join mating groove 10 to further to lower, and can further be convenient to coordinate tooth 20 to be bonded in mating groove 10.
