Description

Technical Field

[0001] The utility model relates to the technical field of flywheel discs, in particular to a flywheel disc structure. Background Art

[0002] The flywheel is a component with a large moment of inertia in the engine crank-connecting rod mechanism. Its main function is to store the energy of the power stroke, overcome the resistance and other resistance of the intake, compression and exhaust strokes, relieve the impact of the crankshaft during movement, and make the crankshaft rotate evenly. At the same time, the flywheel can also use its own inertia to prevent the engine from stalling. With the continuous development of gasoline engine technology, the engine power and torque are getting bigger and bigger. Due to the bad operating habits or low driving level of the driver, the probability of serious slip between the flywheel and the clutch friction plate is getting higher and higher. Since the friction surface of the flywheel and the clutch pressure plate are in a closed environment, the heat is not easy to dissipate. The heat is transferred to the flywheel assembly through the friction surface, thus affecting the performance and reliability of the transmission system.

[0003] To this end, we propose a flywheel disc structure. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a flywheel disc structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a flywheel disc structure, including a flywheel disc body, which is a circular structure as a whole. The flywheel disc body is respectively provided with a groove mounting groove, a connecting shaft and a mounting through hole. The outer wall of the flywheel disc body is installed with a flywheel ring gear, and the side wall surface of the flywheel disc body is respectively fixedly connected with a plurality of external blades and a plurality of cooling fins.

[0006] Preferably, an auxiliary heat dissipation component is provided on the outer wall surface of the flywheel disc body, and the auxiliary heat dissipation component includes a heat dissipation duct opened on the side wall surface of the flywheel disc body, and heat dissipation columns are installed in the heat dissipation duct.

[0007] Preferably, the groove installation slot is opened at the center position of the front side of the flywheel disc body.

[0008] Preferably, the outer blades are fixedly connected to the side wall surface of the flywheel disc body close to the connecting shaft, and the heat dissipation fins are fixedly connected to the side wall surface of the flywheel disc body away from the connecting shaft.

[0009] Preferably, the heat dissipation fins are distributed in a circular pattern on the side wall surface of the flywheel body away from the connecting shaft.

[0010] Preferably, the heat dissipation fins are in an annular structure.

[0011] Beneficial Effects

[0012] The utility model provides a flywheel disc structure, which has the following beneficial effects:

[0013] (1) This flywheel disc structure can increase the heat dissipation wind speed by setting the additional blades, and will not cause too much operating burden on the flywheel disc body. At the same time, the heat dissipation fins on the flywheel disc body cooperate with each other. Since the heat dissipation fins are annular in structure, multiple air ducts can be formed to promote air flow, so that the heat dissipation effect of the flywheel disc body is better, thereby avoiding affecting the performance and reliability of the transmission system.

[0014] (2) This flywheel disc structure, through the cooperation of the heat dissipation duct and the heat dissipation column, makes the side wall surface of the flywheel disc body dissipate heat more quickly, and also plays a role in auxiliary heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS
