Description

Technical Field

[0001] The utility model relates to the technical field of flywheel heat dissipation, in particular to a flywheel structure with efficient heat dissipation. Background Technique

[0002] A flywheel is a disk-shaped part with a large moment of inertia and is mainly used as an energy storage device. The function of the flywheel in a mechanical system is similar to that of a battery in an electronic system, capable of storing and releasing energy. Especially in occasions where continuous and stable power output is required, the role of the flywheel is particularly important. During the power stroke of the engine, the flywheel will accelerate and store energy; while in the non-power stroke, the flywheel decelerates and releases energy to maintain the stable operation of the mechanical system. The efficiency of this energy conversion is very high because the flywheel can store a large amount of kinetic energy when rotating at high speed and quickly release this energy when needed.

[0003] When in use, the flywheel will continuously rub against the pressure plate of the clutch, generating a large amount of heat energy, which affects the service life of the flywheel. The existing flywheels mainly rely on natural heat dissipation to reduce the temperature of the flywheel, resulting in low natural heat dissipation efficiency of the flywheel and easy failure when the internal temperature of the flywheel is too high. Therefore, it does not meet the existing requirements, and a flywheel structure with efficient heat dissipation is proposed for this. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flywheel structure with efficient heat dissipation. Cold air is released to one side of the flywheel body through a cold air duct. The cold air first passes through the heat dissipation channel to reach the other side of the flywheel body, and then the cold air is guided by the air deflector into the clutch friction groove. The cold air will absorb the heat inside the flywheel body in the heat dissipation channel, and at the same time, the cold air will also absorb the heat inside the clutch friction groove, thereby achieving the purpose of reducing the internal temperature of the flywheel body and improving the service life of the flywheel body, and can solve the problems in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A flywheel structure with efficient heat dissipation includes a flywheel body and also includes a flywheel housing. The flywheel housing is located outside the flywheel body. An air deflector is provided on the side of the flywheel body, a weight reduction groove is provided on the other side of the flywheel body, a plurality of air outlets are provided on the outer ring surface of the flywheel body. A first windward surface is provided on one side of the air deflector, a second windward surface is provided on the other side of the air deflector, an arc-shaped plate and an air inlet are provided inside the weight reduction groove, a cold air duct and a second screw hole are provided on the side of the flywheel housing, and a reinforcing rib is provided between two adjacent first screw holes.

[0006] Preferably, a heat dissipation channel is provided inside the flywheel body. The air inlet is located inside the arc-shaped plate, an annular inclined surface is provided at one end of the air inlet, and the air inlet and the air outlets are respectively located at both ends of the heat dissipation channel.

[0007] Preferably, one end of the cold air duct passes through the flywheel housing and extends into the interior of the weight reduction groove, and the other end of the cold air duct extends to the outside of the flywheel housing.

[0009] Preferably, a clutch friction groove and a boss are provided on the side surface of the flywheel body. The boss is located outside the clutch friction groove and is connected to the flywheel body. The air guide plate is mounted on the boss.

[0010] Preferably, a positioning hole is provided inside the boss, and a third screw hole is provided inside the air guide plate. One end of the screw passes through the third screw hole and the positioning hole in sequence and extends into the interior of the flywheel body.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model releases cold air to one side of the flywheel body through the cold air duct. As the flywheel body rotates, the arc plate introduces the cold air into the interior of the heat dissipation channel. The cold air first passes through the heat dissipation channel to reach the other side of the flywheel body, and then the cold air is guided by the air guide plate into the interior of the clutch friction groove. The cold air will absorb the heat inside the flywheel body in the heat dissipation channel, and at the same time, the cold air will also absorb the heat inside the clutch friction groove, so as to achieve the purpose of reducing the temperature inside the flywheel body and improving the service life of the flywheel body.

[0013] 2. The present utility model is provided with a boss outside the clutch friction groove, and an air guide plate is provided on the boss. The air guide plate is provided with a first windward surface and a second windward surface. As the flywheel body rotates, after the first windward surface contacts the cold air, the cold air is shunted, and a part of the cold air is guided to the second windward surface. The second windward surface then guides the cold air into the interior of the clutch friction groove, thereby improving the heat exchange efficiency of the air inside the clutch friction groove and improving the efficiency of reducing the surface temperature of the flywheel body.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] To solve the problem that the natural heat dissipation efficiency of the flywheel is low and it is easy to fail when the internal temperature of the flywheel is too high, please refer to Figures 1-4 An embodiment provided by the present invention: A flywheel structure with efficient heat dissipation, including a flywheel body 1, and further including a flywheel housing 2. The flywheel housing 2 is located outside the flywheel body 1. An air deflector 4 is provided on the side surface of the flywheel body 1. A weight reduction groove 103 is provided on the other side surface of the flywheel body 1. A plurality of air outlets 109 are provided on the outer ring surface of the flywheel body 1. A first windward surface 401 is provided on one side of the air deflector 4, and a second windward surface 402 is provided on the other side of the air deflector 4. An arc plate 105 and an air inlet 104 are provided inside the weight reduction groove 103. A cold air duct 201 and a second screw hole 202 are provided on the side surface of the flywheel housing 2. A reinforcing rib 203 is provided between two adjacent first screw holes 102.

[0021] A heat dissipation channel 110 is provided inside the flywheel body 1. The air inlet 104 is located inside the arc plate 105. An annular inclined surface 1041 is provided at one end of the air inlet 104. The air inlet 104 and the air outlet 109 are respectively located at both ends of the heat dissipation channel 110. One end of the cold air duct 201 passes through the flywheel housing 2 and extends into the weight reduction groove 103, and the other end of the cold air duct 201 extends outside the flywheel housing 2. A ring gear 3 is provided on the outer ring surface of the flywheel body 1. A crankshaft mounting seat 101 and a first screw hole 102 are provided inside the flywheel body 1.

[0022] The cold air duct 201 releases cold air to one side of the flywheel body 1. As the flywheel body 1 rotates, the arc-shaped plate 105 introduces the cold air into the interior of the heat dissipation channel 110. The cold air first enters the air inlet 104, then passes through the heat dissipation channel 110, and finally passes through the air outlet 109 to reach the other side of the flywheel body 1. Subsequently, the cold air is guided by the air deflector 4 into the interior of the clutch friction groove 107. The cold air absorbs the heat inside the flywheel body 1 in the heat dissipation channel 110, and at the same time, the cold air also absorbs the heat inside the clutch friction groove 107, thereby achieving the purpose of reducing the temperature inside the flywheel body 1 and further improving the service life of the flywheel body 1.

[0023] On the side of the flywheel body 1, there are a clutch friction groove 107 and a boss 108. The boss 108 is located outside the clutch friction groove 107. The boss 108 is connected to the flywheel body 1. The air deflector 4 is installed on the boss 108. There is a positioning hole 106 inside the boss 108, and a third screw hole 403 is provided inside the air deflector 4. One end of the screw passes through the third screw hole 403 and the positioning hole 106 in sequence and extends into the interior of the flywheel body 1.

[0024] As the flywheel body 1 rotates, after the first windward surface 401 contacts the cold air, it diverts the cold air and guides a part of the cold air to the second windward surface 402. The second windward surface 402 then guides the cold air into the interior of the clutch friction groove 107, thereby improving the heat exchange efficiency of the air inside the clutch friction groove 107, enhancing the efficiency of reducing the surface temperature of the flywheel body 1, and further improving the working stability of the flywheel body 1.

[0025] Working principle: The cold air duct 201 releases cold air to one side of the flywheel body 1. As the flywheel body 1 rotates, the arc-shaped plate 105 introduces the cold air into the interior of the heat dissipation channel 110. The cold air passes through the heat dissipation channel 110 to reach the other side of the flywheel body 1. Subsequently, the cold air is guided by the air deflector 4 into the interior of the clutch friction groove 107. The cold air absorbs the heat inside the flywheel body 1 in the heat dissipation channel 110, and at the same time, the cold air also absorbs the heat inside the clutch friction groove 107, thereby achieving the purpose of reducing the temperature inside the flywheel body 1 and extending the service life of the flywheel body 1.
