Description

Technical Field

[0001] The utility model relates to the technical field of automotive clutches, and particularly relates to a reinforced automotive clutch pressure plate assembly. Background Art

[0002] When an automobile starts, it accelerates gradually from a completely stationary state. If the transmission system is rigidly connected to the engine, once the transmission is put into gear, the automobile will suddenly rush forward and then stall. Because when the automobile moves from stationary to rushing forward, it has a large inertia, which causes a large resistance torque to the engine. Under the action of this inertial resistance torque, the engine speed drops sharply to below the lowest stable speed instantaneously, and the engine stalls and cannot work. Therefore, a clutch appears. The clutch disc in the clutch is connected to the transmission system. Pressing the clutch pedal can separate the clutch disc from the engine flywheel. After the engine starts and the flywheel rotates, gradually releasing the clutch pedal, the clutch disc will gradually fit tightly with the flywheel under the pressure of the internal pressure plate and be driven by the flywheel to make the automobile start gradually.

[0003] A reinforced automotive clutch pressure plate assembly is disclosed in the patent with the publication number CN215634543U, which includes a diaphragm spring. The diaphragm spring is annular, and a plurality of reed pieces are arranged inside the diaphragm spring. Pressure blocks are arranged on the plurality of reed pieces, pressure grooves are arranged on the pressure blocks, and a shaft hole is arranged in the middle of the plurality of reed pieces.

[0004] In the above technology, by arranging pressure blocks on the reed pieces, the thickness of the contact position between the reed pieces and the release bearing is increased to avoid the thinning of the reed pieces and the deterioration of elasticity when the existing diaphragm spring is used for a long time. However, the reed pieces need to be repeatedly pressed to achieve the effect of automobile braking, and the reed pieces will repeatedly touch the diaphragm spring, resulting in increased wear of the diaphragm spring, frequent maintenance, and possible performance degradation of the components due to overheating of the diaphragm spring. The firmness between the diaphragm spring and the cover fixing ring needs to be strengthened. Therefore, innovation is made on this technology. Summary of the Utility Model

In the environment where the diaphragm spring 1 rubs repeatedly, the wear-resistant material can effectively reduce wear.

[0025] Embodiment 2:

[0026] On the basis of Embodiment 1, as Figure 1 and Figure 4As shown, a fiber filament layer 17 is provided inside the diaphragm spring 1. The other side of the noise reduction layer 16 is attached to one side of the fiber filament layer 17. The reinforcing ring 8 is fixedly sleeved on one end of the diaphragm spring 1. The diaphragm spring 1 is connected to the cover plate 4 through a connecting ring 10. In a strengthened automotive clutch pressure plate assembly of the present utility model, by providing a compressive strip 13, a compressive ring 14, a heat conducting layer 15, a concave hole 9 and a heat dissipation groove 7, both the compressive strip 13 and the compressive ring 14 are made of aluminum alloy material and have good hardness. Through the support of the compressive ring 14 and multiple compressive strips 13 on the back of the diaphragm spring 1, the anti-external force performance on one side of the diaphragm spring 1 is enhanced. The heat conducting layer 15 is made of copper, which helps to effectively dissipate and conduct heat.

[0027] Working principle: The clutch disc in the clutch is connected to the transmission system. Pressing the clutch pedal can separate the clutch disc from the engine flywheel. After the engine starts and the flywheel rotates, gradually releasing the clutch pedal, the clutch disc will gradually fit tightly with the flywheel under the pressure of the internal pressure plate and be driven by the flywheel, enabling the vehicle to start gradually. After the pressure plate assembly is fixed on the flywheel, the pressure plate presses the clutch disc to make it contact and transmit with the flywheel. When pressing the clutch, the transmission mechanism presses down the release bearing, and the release bearing presses down the reed 2. At this time, the reed 2 is still rotating. When the pressure of the clutch pressure plate is released, the contact between the clutch disc and the flywheel is released. In this way, the power of the engine is no longer transmitted to the transmission, allowing the driver to change gears without being affected by the engine speed. When the driver releases the clutch pedal, the spring in the clutch pressure plate assembly will reapply pressure to press the clutch disc tightly against the flywheel, thus restoring the power transmission between the engine and the transmission. The diaphragm spring 1 and the cover plate 4 are laser-fixed using the connecting ring 10. To enhance the firmness of the two, one end of multiple reinforcing strips 12 is sequentially inserted into the corresponding concave holes 9, and the two are threadedly connected. Subsequently, the reinforcing ring 8 and the connecting ring 10 can be limited and fixed. The noise reduction layer 16 is made of polyurethane material, which can absorb and block sound waves, reducing noise propagation and interference. The fiber filament layer 17 is made of aramid fiber, which can enhance the strength and durability of the diaphragm spring 1. The heat insulation layer 18 is made of ceramic fiber. The heat insulation material can help keep the device working within an appropriate temperature range and prevent overheating from having a negative impact on the performance of the diaphragm spring 1. The wear-resistant layer 19 is made of hardened steel material. In an environment where the diaphragm spring 1 rubs repeatedly, the wear-resistant material can effectively reduce wear, thereby extending the service life of the diaphragm spring 1. The compression bars 13 and the compression ring 14 are both made of aluminum alloy material and have good hardness. By supporting the back of the diaphragm spring 1 through the compression ring 14 and multiple compression bars 13, the anti-extrusion performance on one side of the diaphragm spring 1 is enhanced. The heat conduction layer 15 is made of copper, which helps to dissipate heat effectively and conduct heat, maintaining the temperature stability of the diaphragm spring 1 during operation. The heat dissipation grooves 7 enhance the heat dissipation by increasing the surface area and promoting air flow. The heat can be quickly transferred to the surface of the heat dissipation grooves 7 and carried away by the surrounding air, thus improving the quality of heat dissipation.
