Description

Flywheel with automatically adjustable rotary inertia

Technical Field

The invention relates to a flywheel with automatically adjustable rotary inertia.

Background

The flywheel is a metal disc-shaped energy storage device with a large mass.

The automobile flywheel is arranged at the power output end of the crankshaft, and the crankshaft is rotationally connected to the engine frame. The crankshaft supplies the non-working stroke requirement to drive the whole crankshaft connecting rod structure to cross the upper and lower dead points. When the rotating speed of the machine is increased, the kinetic energy of the flywheel is increased, and the energy is stored; when the rotating speed of the machine is reduced, the kinetic energy of the flywheel is reduced, and the energy is released.

The traditional engine flywheel design needs larger inertia due to the consideration of low speed and idling; when the flywheel runs at high speed, redundant inertia is generated by the flywheel, so that the acceleration performance is influenced.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the flywheel with the rotation inertia capable of being automatically adjusted, and the purpose of improving the acceleration performance is achieved by separating the driving flywheel from the driven flywheel.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a but flywheel of rotary inertia automatic adjustment, includes initiative flywheel and driven flywheel, the initiative flywheel be fixed in on the bent axle, driven flywheel rotate to be connected in the engine frame, the initiative flywheel pass through stop device and be connected with driven flywheel, driven flywheel rotates and separates with stop device along with the initiative flywheel is high-speed.

By adopting the technical scheme, when the engine is started, the driving flywheel and the driven flywheel are connected through the limiting device, so that the crankshaft can rotate; along with the promotion of bent axle rotational speed, the initiative flywheel high-speed rotation, driven flywheel and stop device separation alleviate the bent axle burden to when accelerating, the bent axle can respond faster and promote the rotational speed, thereby reach the purpose that promotes acceleration performance.

The invention is further configured to: stop device include grip block, regulation pole, elastic component and limiting plate, initiative flywheel on seted up spout and mounting hole, spout and mounting hole intercommunication, grip block sliding connection in the spout and be used for conflicting with driven flywheel, the regulation pole pass the mounting hole and with grip block fixed connection, the limiting plate be fixed in on the regulation pole, the both ends of elastic component respectively with inner wall, the limiting plate connection of mounting hole.

By adopting the technical scheme, when the driving flywheel rotates at a high speed along with the crankshaft, the clamping plate moves towards the direction far away from the driving flywheel under the action of centrifugal force, and then the clamping plate is separated from the driven flywheel, so that the crankshaft can improve the acceleration performance; when the flywheel is in low speed or idling, the rotating speed of the crankshaft and the driving flywheel is low, the clamping plate moves towards the direction close to the driving flywheel under the elastic action of the elastic piece, and the driven flywheel is fixed on the driving flywheel through the clamping plate.

The invention is further configured to: the adjusting rod comprises a connecting rod and a spiral wire, the spiral wire is fixed on the outer wall of the connecting rod, and the spiral wire is in threaded connection with the clamping plate.

Through adopting above-mentioned technical scheme, rotate the connecting rod, can adjust the deformation volume of elastic component, adjust elasticity to make initiative flywheel and driven flywheel separation under the different rotational speed of adaptation, promote the practicality.

The invention is further configured to: and one end of the limiting plate, which is far away from the adjusting rod, is provided with a mounting groove.

Through adopting above-mentioned technical scheme, the setting of mounting groove can be convenient for drive the regulation pole and rotate.

The invention is further configured to: and a fixing ring for connecting the bearing is fixed on the outer wall of the driven flywheel.

By adopting the technical scheme, the connection between the bearing and the driven flywheel is more stable.

In conclusion, the invention has the following beneficial effects:

along with the promotion of bent axle rotational speed, the initiative flywheel high-speed rotation, driven flywheel and stop device separation alleviate the bent axle burden to when accelerating, the bent axle can respond faster and promote the rotational speed, thereby reach the purpose that promotes acceleration performance.

Detailed Description

The invention is further described with reference to the accompanying drawings.

As shown in fig. 1 to 3, a flywheel with an automatically adjustable rotational inertia includes a driving flywheel 11 and a driven flywheel 12. The driving flywheel 11 is fixed on the crankshaft; the driven flywheel 12 is rotatably connected to the engine frame through a bearing. The driving flywheel 11 is connected with the driven flywheel 12 through the limiting device 2.

The limiting device 2 comprises a clamping plate 21, an adjusting rod 22, an elastic piece 23 and a limiting plate 24. The driving flywheel 11 is provided with a chute 31 and a mounting hole 32, and the chute 31 is communicated with the mounting hole 32. The holding plate 21 is slidably connected to the slide groove 31 and is configured to abut against the outer circumference of the driven flywheel 12. The adjusting rod 22 passes through the mounting hole 32 and is fixedly connected with the clamping plate 21, and the limit plate 24 is fixed on one end of the adjusting rod 22 far away from the clamping plate 21. The elastic member 23 is sleeved on the adjusting rod 22, and two ends of the elastic member are respectively connected with the inner wall of the mounting hole 32 and the limiting plate 24.

The adjustment lever 22 includes a connection rod 61 and a spiral wire 62. The spiral wire 62 is fixed to the outer wall of the connecting rod 61, and the spiral wire 62 is screwed to the holding plate 21.

In order to facilitate the rotation of the adjustment lever 22, an installation groove 4 is formed at one end of the stopper plate 24, which is away from the adjustment lever 22. The mounting groove 4 is in a straight shape or a cross shape.

The outer wall of the driven flywheel 12 is fixed with a fixing ring 5 used for being connected with a bearing, and the fixing ring 5 and the driven flywheel 12 are coaxially arranged.

Along with the increase of the rotating speed of the crankshaft, the driving flywheel 11 rotates at a high speed, and under the action of centrifugal force, the clamping plate 21 moves in the direction away from the driving flywheel 11 and is separated from the driven flywheel 12, so that the burden of the crankshaft is reduced, and therefore, the crankshaft can respond more quickly and increase the rotating speed when accelerating, and the purpose of improving the acceleration performance is achieved. When the rotation speed is reduced, the clamping plate 21 can clamp the driven flywheel 12 again through the elastic force of the elastic piece 23.
