Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a friction clutch pressure plate assembly, which includes a flywheel 11, a friction disk 9 contacting with the flywheel 11, a driven disk 10 connected with the friction disk 9, a transmission input shaft 4 connected with the driven disk 10 through a spline 18, and a pressure plate assembly, wherein the pressure plate assembly includes a housing 1 connected with the flywheel 11 through a first bolt 8, a pressure plate 7 inside the housing 1, a release bearing 5 sleeved outside the transmission input shaft 4, a diaphragm spring 6 between the pressure plate 7 and the release bearing 5, the friction disk 9 is pressed by the pressure plate 7 to contact with the flywheel 11 for power transmission, the housing 1 rotates with the flywheel 11, when the pedal is stepped on, the release fork 5 moves to the left, the release bearing 5 moves to the left, the inner periphery of the diaphragm spring 6 moves to the left, then the edge of the diaphragm spring 6 tilts to the right, the pressure plate 7 is pulled to move to the right to separate from the friction disk 9, the power transmission is interrupted, which is the basic working principle of the clutch and is the prior art;

different from the prior art, the dust-proof pipe 12 is detachably mounted at the position of the through hole 2 of the housing 1 of the platen assembly, as shown in fig. 2, a breathable dust-proof net 13 is fixed on the inner surface of the upper end of the dust-proof pipe 12, a through hole 15 is formed in the middle of the breathable dust-proof net 13, the transmission input shaft 4 and the release bearing 5 penetrate through the through hole 15 and the dust-proof pipe 12, a dust cover 14 is fixed at the position of the through hole at the upper end of the breathable dust-proof net 13, the dust cover 14 is of a horn cover structure which is hollow inside and narrow at the top and wide at the bottom, the inner surface of the upper end of the dust cover 14 is in contact with the outer surface of the release bearing 5, the upper end of the dust cover 14 and the release bearing 5 can rotate relatively, and the release bearing 5 can move axially in the dust cover 14.

When the friction type clutch pressure plate assembly works, the dust-proof pipe 12 is arranged at the position of the through hole 2 of the shell 1, the end part of the dust-proof pipe 12 is sealed by the breathable dust-proof net 13, when dust is prevented from entering the through hole 2 and the shell 1, heat in the shell 1 can also penetrate through the breathable dust-proof net 13 to be exchanged with the outside for heat dissipation, the breathable dust-proof net 13 is provided with the through hole 15 for the transmission input shaft 4 to penetrate, the through hole 15 is sealed by the dust cover 14, the dust is prevented from entering the through hole 15, the upper end of the dust cover 14 of the horn cover is in contact with the release bearing 5, dust and dust are prevented, when the clutch stops working and power is transmitted, the flywheel 11, the shell 1 and the dust-proof pipe 12 still rotate, and when the transmission input shaft 4 and the release bearing 5 stop rotating, the dust cover 14 still can rotate on the outer surface of the release bearing 5 to prevent dust.

Specifically, a mounting ring 16 is fixed at the end of the dustproof pipe 12, a second bolt 17 is connected between the mounting ring 16 and the housing 1 in a threaded manner and used for mounting and fixing the dustproof pipe 12, and when the flywheel 11 is separated from the housing 1 and the housing 1 is moved to the left and separated from the input shaft 4 of the transmission, the dustproof pipe 12 and the housing 1 can be separated by detaching the second bolt 17.
