Background technique

Today's automobile clutches include friction clutches, fluid couplings, and electromagnetic clutches. They all use soft contact, that is, friction, hydraulic force, or electromagnetic force, to transmit the rotational power of the engine. The power transmission efficiency of these soft contacts is relatively high. Low; the reason why the modern developed automobile industry still uses the soft contact clutch method with low power transmission efficiency is because the meshed gears are difficult to separate when the gear meshing transmission rotates at high speed, and no hard transmission that is easy to mesh has not been found yet. The gear separation and gear meshing transmission method with higher transmission efficiency is a difficult problem in improving the transmission efficiency of automobiles; Wei Boqing's multiple invention patents "201410151795.6 Threaded sleeve clutch", "201410162087.2 Spring pressure friction gear meshing clutch", " 201410167388.4 Steel Disc Type Buffer Friction Gear Engagement Clutch", "201410169746.5 Compression Spring Type Buffer Friction Gear Engagement Clutch", "201410173268.5 Double Claw Disc Buffer Friction Thread Socket Clutch" can achieve high-efficiency transmission of gear clutch engagement, but the structure is complex, The volume is large, and the most important thing is that the present invention can utilize the relative spacing of the same-polar permanent magnets, so that the same-polar permanent magnets that are relatively spaced cannot be attracted to each other under the same speed rotation condition, so that The meshing of the side gears is guaranteed to be smooth, stable and free of toothing; the invention provides a high-efficiency transmission structure of gear clutch meshing through electromagnetic control and dislocation attraction of the same pole permanent magnet blocks at annular intervals.

The distance between the magnetic blocks on the right side is greater than the width of the magnetic blocks on the right side of each driven wheel, so that the space between the right magnetic blocks of every two driven wheels can accommodate one magnetic block on the right side of the driven wheel, The area between the magnetic blocks on the right side of the driven wheel is installed with a magnetic block on the right side of the driven wheel. The width of the magnetic block on the right side of each driven wheel is greater than the width of the magnetic block on the right side of the driven wheel. The annular ring formed by the magnetic block between blocks, the end face on the right side is on the same plane, and is not on the same plane as the plane formed by the right end face of the magnetic block on the right side of all driven wheels. The plane of the right end face of the magnetic block is indented by a certain distance from the plane of the right end face of the magnetic block on the right side of the driven wheel, that is, the distance from the right end plane of the magnetic block between the magnetic blocks on the right side of the driven wheel to the right side of the driven wheel is less than the distance from the right side of the driven wheel The distance from the plane of the right end face of the magnetic block to the right side of the driven wheel, the axis line of the annular ring formed by the magnetic blocks on the right side of all driven wheels overlaps with the axis line of the driving shaft, and the axis line of all the right magnetic blocks of the driven wheel The axis line of the formed annular ring overlaps with the axis line of the driving shaft; the magnetic block on the right side of the driven wheel is matched with the magnetic block on the left side of the driving wheel, and the size and shape of the magnetic block on the right side of the driven wheel are the same as those on the left side of the driving wheel. The size and shape of the magnetic blocks are the same, the size and shape of the magnetic block between the magnetic blocks on the right side of the driven wheel and the size and shape of the magnetic block on the left side of the driving wheel are the same, and the annular ring formed by the magnetic blocks on the right side of the driven wheel The radius of the outer circle is equal to the radius of the outer circle of the ring formed by the magnetic block on the left side of the driving wheel, the radius of the inner circle of the ring formed by the magnetic block on the right side of the driven wheel, and the inner circle of the ring formed by the magnetic block on the left side The radii are equal; the outer radius of the annular ring formed by the magnetic blocks on the right side of the driven wheel is equal to the outer radius of the annular ring formed by the magnetic blocks on the left side of the driving wheel.

3. The "closing" process of the clutch: the computer energizes the electromagnetic coil that rotates with the driving wheel and the outer wheel of the driving wheel at the same angular velocity, and the electromagnetic coil generates a magnetic field. The direction of this magnetic field corresponds to that of the permanent magnet ring on the right side of the driven wheel The direction of the magnetic field is the same, so that the electromagnetic coil is attracted to the permanent magnetic ring on the right side of the driven wheel, and the permanent magnetic ring on the right side of the driven wheel pulls the electromagnetic coil to the left, and the electromagnetic coil moves to the left and generates a ring on the outer surface of the outer wheel of the driving wheel. The displacement to the left causes the electromagnetic coil supporting slider fixedly connected with the electromagnetic coil to have an equal leftward displacement together, so that the spring connected to the electromagnetic coil supporting slider produces tensile deformation, and the spring simultaneously pulls and The spring fixing block fixedly connected to the outer wheel of the driving wheel moves to the left, and then pulls the driving wheel and the outer wheel of the driving wheel to move to the left; the driving wheel and the outer wheel of the driving wheel move to the left so that the magnetic block on the left side of the driving wheel and the magnetic block on the right side of the driven wheel are close to each other , because the magnetic block on the left side of the driving wheel and the right magnetic block of the passive wheel are installed opposite to each other, so when the rotation speeds of the driving wheel and the driven wheel are not completely consistent, the magnetic block on the left side of the driving wheel and the right magnetic block of the passive wheel It is impossible to attract and engage with each other, but because the electromagnetic coil slides to the left relative to the outer wheel of the driving wheel, the distance that the electromagnetic coil moves to the left is greater than the distance that the driving wheel and the outer wheel of the driving wheel move to the left. When the electromagnetic coil is very close to the position of the permanent magnet ring on the right side of the passive wheel, there is still a certain distance between the magnetic block on the right side of the driven wheel and the left magnetic block of the driving wheel and is affected by the right magnetic block of the driven wheel and the left magnetic block of the driving wheel. The magnetic repulsion force of the same pole of the driving wheel cannot be close, and the left tooth of the outer wheel of the driving wheel and the right tooth of the driven wheel also maintain a small distance and fail to mesh; because the electromagnetic coil has a large suction force on the permanent magnetic ring on the right side of the driven wheel, The action of this electromagnetic force makes the rotation speed of the driven wheel get closer and closer to the rotation speed of the driving wheel (no matter whether the rotation speed of the driving wheel is greater than the rotation speed of the driven wheel or less than the rotation speed of the driven wheel is the same), when the rotation speed of the driven wheel When the rotation speed is very close to the rotation speed of the driving wheel, the magnetic block on the left side of the driving wheel will immediately enter the space between the magnetic blocks on the right side of the driven wheel, and will be attracted to the magnetic block on the right side of the driven wheel , the magnet block on the right side of the driven wheel will also immediately enter the space between the magnet blocks on the left side of the driving wheel and attract the magnetic block between the magnet blocks on the left side of the driving wheel, because the magnet block on the left side of the driving wheel is designed to When the magnetic blocks on the right side of the driven wheel are attracted together, and the magnetic blocks on the right side of the driven wheel are attracted to the left side of the driving wheel, the teeth on the right side of the driven wheel and the left side teeth of the outer wheel of the driving wheel are just right. It is in the corresponding meshing position, so at this time, the right side teeth of the driven wheel and the left side teeth of the outer wheel of the driving wheel mesh with each other without hitting the teeth. At this point, the "engagement" process of the clutch is completed; the "disengagement" process of the clutch: the computer Give reverse power to the electromagnetic coil attracted by the permanent magnet ring on the right side of the driven wheel, the magnetic field generated by the electromagnetic coil is opposite to the inherent magnetic field direction of the permanent magnet ring on the right side of the driven wheel, and the permanent magnet ring on the right side of the driven wheel turns the electromagnetic coil Push right away from the permanent magnetic ring on the right side of the driven wheel for a certain distance, and the electromagnetic coil moves to the right to drive the driving wheel and the outer wheel of the driving wheel to move to the right at the same time, so that the outer wheel of the driving wheel moves to the left. The side teeth are separated from the right teeth of the driven wheel, and the magnetic block between the left magnetic block of the driving wheel and the right magnetic block of the driven wheel, and the magnetic block between the right magnetic block of the driven wheel and the left magnetic block of the driving wheel Separation, so far, the "off" process of the clutch is completed, and the computer powers off the electromagnetic coil.

Compared with the prior art, the present invention has the following advantages:

1. Existing automotive clutches include friction clutches, hydraulic couplings, and electromagnetic clutches. They all use soft contact, that is, friction, hydraulic force, or electromagnetic force, to transmit the rotational power of the engine. The power transmission of these soft contacts The efficiency is relatively low; and the clutch of the present invention discharges through the relative intervals of the same pole permanent magnet blocks, so that the same pole permanent magnet blocks discharged at relative intervals cannot be attracted to each other under the same speed rotation condition, thereby ensuring The meshing of the side gears is smooth, stable, and does not strike teeth.

2. The present invention passes through the forward and reverse directions of the electromagnetic coil through computer control, so that the direction of the magnetic field generated by the electromagnetic coil is the same as or opposite to that of the corresponding permanent magnetic ring, so as to realize the attraction or push away, and then make the driving wheel and the passive wheel The meshing side gears of the wheels can disengage at the same rotational speed.

The tooth 6 on the left side of the outer wheel of the driving wheel and the tooth 5 on the right side of the driven wheel also maintain a small distance and fail to engage; because the electromagnetic coil 7 has a large suction force on the permanent magnetic ring 15 on the right side of the driven wheel, the effect of this electromagnetic force makes The speed of rotation of the driven wheel 3 is getting closer to the speed of rotation of the driving wheel 10 (no matter whether the speed of rotation of the driving wheel is greater than the speed of rotation of the driven wheel or less than the speed of rotation of the driven wheel is all the same), when the speed of rotation of the driven wheel 3 and When the rotation speed of the driving wheel 10 reaches very close, the magnetic block 12 on the left side of the driving wheel will immediately enter the space between the magnetic blocks 11 on the right side of the driven wheel, and attract 21 pieces of magnetic attraction between the magnetic blocks on the right side of the driven wheel. close, the magnetic block 11 on the right side of the driven wheel will also immediately enter the space between the magnetic blocks 12 on the left side of the driving wheel, and will be attracted to the magnetic block 22 between the magnetic blocks on the left side of the driving wheel, because it is designed on the left side of the driving wheel. When the side magnetic block 12 is attracted to the magnetic block 21 between the magnetic blocks on the right side of the driven wheel, and the magnetic block 11 on the right side of the driven wheel is attracted to the magnetic block 22 between the magnetic blocks on the left side of the driving wheel, the teeth on the right side of the driven wheel will 5 and the left tooth 6 of the outer wheel of the driving wheel are just in the corresponding meshing position, so at this time, the right tooth 5 of the driven wheel and the left tooth 6 of the outer wheel of the driving wheel mesh with each other without tooth hitting, so far, the "engagement" of the clutch The process is completed; the "off" process of the clutch: the computer 16 pulls in the permanent magnet ring 15 on the right side of the driven wheel of the driven wheel 3 The electromagnetic coil 7 of the electromagnetic coil is energized in reverse, and the magnetic field generated by the electromagnetic coil 7 is opposite to the inherent magnetic field direction of the permanent magnetic ring 15 on the right side of the driven wheel, and the permanent magnetic ring 15 on the right side of the driven wheel pushes the electromagnetic coil 7 to the right away from the permanent magnetic ring on the right side of the driven wheel. The magnetic ring 15 has a certain distance, and the electromagnetic coil 7 moves to the right to drive the driving wheel 10 and the driving wheel outer wheel 9 to move to the right simultaneously, so that the left side tooth 6 of the driving wheel outer wheel is separated from the right side tooth 5 of the driven wheel, and is separated from the left side of the driving wheel. The separation of block 12 and the magnetic block 21 between the magnetic block on the right side of the driven wheel, and the separation of the magnetic block 22 between the magnetic block 11 on the right side of the driven wheel and the magnetic block 22 on the left side of the driving wheel, so far, the "off" process of the clutch is completed. The computer 16 de-energizes the electromagnetic coil 7 .
