Description

Technical Field

[0001] The utility model belongs to the technical field of clutches and relates to a clutch driven disc riveting orthopedic device. Background Art

[0002] In the complex process of clutch manufacturing, the riveting of the driven disc is particularly critical. This step determines the firmness of the connection between the driven disc and other components and the overall flatness. However, when the traditional riveting device is in operation, the driven disc often deforms slightly. These deformations may not be obvious in the initial stage, but over time and accumulation, they will gradually affect the overall performance of the clutch. A deformed driven disc may cause instability in the clutch when transmitting power, and may even cause failures, thus affecting the safety and reliability of the car. For example, when the driven disc is deformed, its contact surface with other components will become uneven, resulting in friction and vibration when transmitting power. This will not only reduce the transmission efficiency of the clutch, but may also cause instability under high-speed or high-load conditions, and may even cause serious failures such as slipping or breaking. Such failures will not only affect the driving performance of the car, but may also pose a threat to the safety of the driver and passengers.

[0003] In summary, the existing clutch driven disc riveting device will be deformed during riveting, and this deformation will eventually affect the performance of the clutch driven disc. Utility Model Content
