Description

Background Art

[0002] The gearbox synchro gears currently on the market are all synchronized by grinding between the synchro gears and the synchro rings, which are prone to early wear and abnormal noise. There will also be a collision sound of low-speed gears when the vehicle starts and shifts into gear.

[0003] When the engine is started or running normally, the driver does not step on the clutch. At this time, the speed of the clutch driven plate, pressure plate, and flywheel is basically the same as the engine speed. When the driver steps on the clutch, the clutch driven plate separates from the pressure plate. The clutch driven plate is in a state of relative rotation relative to the speed of the engine pressure plate or flywheel, because it and the gearbox shaft continue to rotate under the action of rotational inertia. Although the speed will become slower and slower, it cannot be quickly reduced in a short period of time. At this time, some drivers are in a hurry to start the whole vehicle, and they immediately shift gears before the speed of the driven plate and the gearbox shaft drops to a certain value. This can easily cause the gearbox gears to collide. In severe cases, the gear collision is accompanied by a rattling sound. Summary of the invention

[0006] Preferably, a gear sensor is provided on the gear to obtain the current gear. Under a preset control program, the current of the coil is adjusted according to the corresponding gear speed so that the speed of the gearbox shaft is consistent with the speed of the relative gear.

[0007] Preferably, the magnet may be a permanent magnet.

[0013] In the figure: magnet 1, coil 2, rotating shaft 3, sink 31, sleeve 4, bracket 5, conductive ring 6, contact ring 7, lead-out terminal 8. DETAILED DESCRIPTION

[0014] Next, combine with Figure 1-2 A specific embodiment of the present invention is described in detail.

[0015] A gearbox active synchronization device capable of providing energy comprises a magnet 1 and a coil 2, wherein the coil 2 is connected to a battery management module, a movable switch is arranged on the circuit path between the coil 2 and the battery management module, and the movable switch is arranged on the clutch pedal. After the clutch pedal is stepped on, the coil 2 forms a path with the drive module, and after the clutch pedal is released, the coil 2 is disconnected from the battery management module. One of the magnet 1 and the coil 2 is arranged on a rotating shaft of the gearbox and rotates synchronously with the gearbox. The magnet 1 forms a magnetic field, and the coil 2 cuts the magnetic flux lines in the magnetic field. According to Faraday's law of electromagnetic induction, current will be generated in the coil 2 and transmitted to the battery management module through a wire. Similarly, the gearbox shaft receives a resistance torque and the rotation speed drops rapidly, that is, the kinetic energy of the gearbox is actually converted into electrical energy.

[0016] The magnet 1 and the coil 2 form a simple generator principle, enter the charging mode, and reduce the speed of the gearbox shaft. In this way, when the vehicle starts or needs to increase or decrease gears during normal operation, the gears of the gearbox can be well synchronized.

[0017] However, when the vehicle needs to downshift to increase torque during normal operation, the charging mode is contrary to the expected expectation. Based on this, the present invention sets a gear sensor on the gear to obtain the current gear. After stepping on the clutch pedal and obtaining the downshift information, the coil 2 forms a path with the drive module to enter the motor drive mode, and the current of the coil can be adjusted according to the corresponding gear speed under the preset control program, so that the speed of the gearbox shaft is consistent with the speed of the relative gear, so that the gear can be easily engaged.

[0018] Whenever the gear is increased or decreased, the clutch driven plate and the pressure plate are in meshing state, and the coil 2 and the magnet 1 are in power generation mode to charge the battery in the battery management module of the vehicle.

[0019] The premise for the present invention to be realized is the relative rotation between the magnet 1 and the coil 2, so that the coil 2 can cut the magnetic flux lines generated by the magnet 1, and the magnet 1 can be a permanent magnet.

[0020] In an embodiment 1, a groove 31 is provided in the rotating shaft 3 of the gearbox, the coil 2 is provided in the groove 31, and the magnet 1 is provided on a sleeve 4 sleeved on the rotating shaft 3. After the clutch pedal is stepped on, coil 2 forms a path with the drive module. The gearbox input shaft speed can be adjusted according to the relevant gear position and speed to achieve synchronization of related gears. After the clutch pedal is pressed, coil 2 is disconnected from the drive module and connected to the battery circuit module, entering the power generation mode. During the rotation of the coil 2, the magnetic flux passing through the coil 2 changes continuously, that is, an induced current is generated in the coil 2. The brushes, commutator and other components involved are common sense components and will not be elaborated in detail.

[0021] In this embodiment, the end of the coil 2 can be led out from the sink 31, but the strength of the rotating shaft 3 of the gearbox will be reduced, and it is very easy to deform under high load and high temperature in the operating environment.

[0022] Based on this, in another embodiment 2, the coil 2 is fixed to the surface of the rotating shaft 3 through a bracket 5, and the magnet 1 is relatively arranged on both sides of the rotating shaft 3 and can be fixed on the sleeve 4, which ensures the strength of the rotating shaft 3. However, the lead wire will inevitably be wound around the rotating shaft during rotation. To solve this problem, this embodiment is provided with a conductive ring 6 fixed on the sleeve 4 coaxial with the rotating shaft 3, a contact ring 7 is provided at the lead end of the coil 2, and the contact ring 7 is sleeved on the conductive ring 6. A lead end 8 is provided in the middle part of the outer side of the conductive ring 6, and the lead end 8 is connected to the movable switch through a wire; during the rotation process, the coil 2 will no longer interfere with other components.

[0023] The present invention effectively solves the problem of low-speed gear collision noise during the vehicle starting and shifting gears, prolongs the service life of synchronous teeth, reduces the driver's workload, eliminates gear collision and gear collision noise during vehicle starting and shifting gears, improves the gear shifting strength and service life of synchronous teeth during normal vehicle operation, and increases power generation points.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
