[0021] Please see Figure 1This utility model provides a high-strength forged aluminum pressure plate, including a composite pressure plate 1. The composite pressure plate 1 includes a holding layer 11, a heat-conducting layer 12, connecting ears 13, and heat dissipation grooves 14. The holding layer 11 and the heat-conducting layer 12 are stacked and assembled into one piece. The holding layer 11 is the working surface of the composite pressure plate 1, and the heat-conducting layer 12 is the back surface of the composite pressure plate 1. At least three connecting ears 13 are evenly distributed along the edge of the holding layer 11. The connecting ears 13 are integrally cast with the holding layer 11. At least six heat dissipation grooves 14 are arranged around the back surface of the heat-conducting layer 12.

[0022] This utility model provides a high-strength forged aluminum pressure plate. The pressure holding layer 11 is made of gray cast iron, and the heat-conducting layer 12 is made of forged aluminum. Gray cast iron has stable mechanical strength, ensuring the service life of the pressure holding layer 11. Forged aluminum has excellent lightweight and thermal conductivity. The lightweight design can reduce the rotational mass of the composite pressure plate 1, which helps to improve the shifting response speed. The high thermal conductivity allows the heat-conducting layer 12 to help the pressure holding layer 11 dissipate heat quickly, avoiding overheating failure of the composite pressure plate 1.

[0023] Please see Figure 5 This utility model provides a high-strength forged aluminum pressure plate with a heat dissipation groove 14 having an inverted T-shaped cross-section and both ends of the heat dissipation groove 14 extending to the inner and outer edges of the heat-conducting layer 12 to optimize the airflow path and improve convection efficiency.

[0024] Please see Figure 3-4 This utility model provides a high-strength forged aluminum pressure plate. The back of the pressure holding layer 11 is provided with no less than 6 heat-conducting pillars 15, and the front of the heat-conducting layer 12 is provided with pillar grooves 16. The number of pillar grooves 16 and the heat-conducting pillars 15 are the same and their positions are corresponding. The positions of the pillar grooves 16 and the heat dissipation grooves 14 are staggered. The heat-conducting pillars 15 and the pillar grooves 16 are nested and inserted into each other. The heat dissipation area is further expanded by the structural cooperation of the heat-conducting pillars 15 and the pillar grooves 16, so that the heat-conducting layer 12 can quickly remove the heat accumulated in the pressure holding layer 11 and avoid overheating failure.

[0025] To further explain, the heat-conducting pillar 15 and the pressure-holding layer 11 are integrally cast structures to ensure heat transfer performance.

[0026] This utility model provides a high-strength forged aluminum pressure plate, in which a graphene pad 17 is laid on the front side of the heat-conducting layer 12. The area ratio of the graphene pad 17 to the front side of the heat-conducting layer 12 is not less than 70%. The graphene pad 17 can optimize the heat transfer efficiency between the pressure holding layer 11 and the heat-conducting layer 12, and ensure the heat dissipation effect.

[0027] The working principle is as follows: By setting up a compound pressure plate 1, the compound pressure plate 1 is first installed and connected to the disc housing through the connecting ear 13, and thus assembled into the clutch system; During use, the pressure holding layer 11 is the working surface of the composite pressure plate 1. The pressure holding layer 11 is made of gray cast iron, which gives the pressure holding layer 11 stable mechanical strength and ensures service life. The heat conducting layer 12 is the back side of the composite pressure plate 1. The heat conducting layer 12 is made of forged aluminum, which gives the heat conducting layer 12 excellent lightweight and thermal conductivity. The lightweight design can reduce the rotational mass of the composite pressure plate 1, which helps to improve the shifting response speed. The high thermal conductivity allows the heat conducting layer 12 to help the pressure holding layer 11 dissipate heat quickly to achieve a more stable working state. By setting heat dissipation grooves 14 on the back of the heat-conducting layer 12, air convection is generated by the heat dissipation grooves 14, thereby helping the heat-conducting layer 12 to dissipate heat quickly. By setting heat-conducting pillars 15 and grooves 16 between the pressure-holding layer 11 and the heat-conducting layer 12, the structural cooperation of the heat-conducting pillars 15 and grooves 16 enhances the torsional resistance of the pressure-holding layer 11 and the heat-conducting layer 12, ensures structural strength, and further expands the heat dissipation area. The pressure-holding layer 11 can quickly transfer heat to the heat-conducting layer 12 through the heat-conducting pillars 15 for dissipation, thus avoiding overheating failure of the pressure-holding layer 11.
