An inner seal cover is connected to the inner end face of the constant velocity universal joint housing. The connecting sleeve includes a first connecting section and a second connecting section, and the first connecting section and the second connecting section are integrally formed. An annular groove is formed at the top of the second connecting section. A connecting block is connected to the outer wall of one end of the inner seal cover away from the inner end face of the constant velocity universal joint housing, and the connecting block is connected to an annular convex block that can be snapped into the groove.

[0006] Further, an annular groove is formed on the outer wall of the connecting sleeve, and a sealing rib that can be snapped into the annular groove is provided on the inner wall of the corrugated seal cover.

[0007] Further, an installation groove is formed on the outer wall of the bottom end of the corrugated seal cover, and a fastener for connecting the connecting sleeve and the corrugated seal cover together is provided in the installation groove.

[0008] Further, the fastener is a clamp, and the clamp is assembled in the installation groove.

[0009] Further, an arch is formed on one side of the top of the second connecting section located in the groove.

[0010] Further, a sealing groove is formed on the outer wall of the constant velocity universal joint housing, and a sealing ring that mates with the sealing groove is assembled on the inner wall of the bottom end of the connecting sleeve.

[0011] Compared with the prior art, the present utility model provides a connecting sleeve for a dust cover of an automotive transmission system, which has the following beneficial effects: for the connecting sleeve of the automotive transmission system dust cover, a connecting sleeve is installed on the constant velocity universal joint housing, the outer wall of the connecting sleeve is connected to a corrugated sealing cover, and the top end of the connecting sleeve is connected to an inner sealing cover, so that the constant velocity universal joint has good sealing performance, and the grease inside it is not easily leaked from the connection between it and the connecting sleeve.
