Problems solved by technology
However, in this patent, the designed guide groove is radially from the heat dissipation through hole to the inner edge of the pressure plate, so that the hot air flows to the center of the pressure plate to converge, which is not conducive to the rapid heat dissipation of the pressure plate
[0004] Therefore, the heat dissipation capacity of the existing clutch pressure plate is limited, and it cannot quickly dissipate heat and reduce the temperature rise of the pressure plate, which will eventually lead to clutch slippage and burnout failure

The invention discloses a channel-type clutch pressure plate, which includes an annular body. The heat dissipation through hole; the heat dissipation through hole, the radial heat dissipation channel, and the circumferential heat dissipation channel communicate with each other; the radial heat dissipation channel is an arc-shaped channel, the outer end of which extends to the outer edge of the ring body, and the inner end extends to the ring body the inner edge; the radial heat dissipation channel is a right spiral arc channel. The invention can effectively and quickly dissipate heat, reduce the temperature rise of the pressure plate, and has high strength and rigidity, so that the clutch is not easy to slip and burn.
Description
technical field [0001] The invention belongs to the technical field of auto parts, and relates to a clutch, in particular to a channel-type clutch pressure plate. Background technique [0002] The pressure plate is an annular metal disc, which is usually a solid structure and is often used in automobile clutches. The clutch pressure plate of an automobile is prone to clutch slipping and burning disc failures during heavy-load starting and uphill acceleration. The main reason for the failure is that during the clutch engagement process, sliding friction occurs between the clutch friction plate and the pressure plate, and the friction work will be converted into heat energy, which will increase the temperature of the pressure plate and reduce the torque transmission capacity, which will eventually lead to clutch slipping and burning plate failure. [0003] In order to solve this problem, the Chinese patent "pressure plate" with publication number CN203756784U discloses such a...
