一种湿式离合器的挡板弹性挡圈防脱结构及湿式离合器
By employing a splined section and a boss section design in the wet clutch, the relative movement between the baffle and the baffle elastic retaining ring is restricted, thus solving the problem of the baffle elastic retaining ring disengaging. This achieves the reliability and detachability of the baffle elastic retaining ring, and improves the working stability of the clutch.

AI Technical Summary
In harsh operating conditions, the elastic retaining ring of the wet clutch plate is prone to dislodging, leading to clutch failure. Existing technology lacks an effective limiting structure.
The baffle structure, which engages with the spline section and the inner spline of the clutch outer hub, combined with the boss section design, restricts the relative movement between the baffle and the baffle elastic retaining ring. Through the axial length of the spline section and the size design of the boss section, the detachability and axial limit of the baffle elastic retaining ring are ensured, preventing it from coming off.
This effectively prevents radial deformation and dislodgement of the elastic retaining ring of the baffle, ensuring the normal working position and disassembly of the clutch, and improving the reliability of the clutch.
