Example Embodiment

[0027] Such as Figure 1-4 A friction clutch includes a flywheel 1 and a pressure plate 2 of the driving part, a driven disc 3 of the driven part, at least one annular groove is provided on the friction surface of the driven disc 3, and the friction surface of the pressure plate and the flywheel is a ring Matching surface with grooves.

[0028] Such as figure 1 In the friction clutch, the annular groove is an annular curved groove 31, and the friction surfaces of the pressure plate and the flywheel are annular curved ribs matching the annular curved groove.

[0029] Such as figure 2 In the friction clutch, the annular curved groove is an annular arc groove 32, and the friction surface of the pressure plate is an annular arc convex rib surface 22 that matches with the annular arc groove. The friction of the flywheel The surface is an annular arc convex rib surface 12 that matches with the annular arc groove.

[0030] Such as image 3 In the friction clutch, the annular groove is an...

Abstract

Disclosed is a friction clutch. The friction clutch comprises a driving part including a flywheel and a pressing disc, and a driven part including and a driven disc. The friction surface of the driven disc is provided with at least one ring groove, and the friction surfaces of the pressing disc and the flywheel are matched with the ring grooves. According to the friction clutch, the grooves arranged in the friction surfaces enlarge the friction area and omit large treading force or large oil pressure; large friction force can be generated without the friction a large-diameter pressing disc, so that the size and the cost of the friction clutch can be reduced. For ring V-shaped grooves matched with ring V-shaped ribs, when the ring V-shaped grooves and the ring V-shaped ribs are completely close to each other, namely, provided with the same included angle, due to the facts that the average width of the V-shaped ribs is slightly larger than that of the V-shaped grooves and the top end of every V-shaped rib is in an arc shape, the grooves can generate large clamping force once the V-shaped ribs move forwards a little, and accordingly the friction force can be effectively transmitted, and the size and the cost of the friction clutch can be further reduced; the same is true for ring trapezoid ribs matched with ring trapezoid grooves.

Description

technical field [0001] The invention relates to a component directly connected with an engine in an automobile transmission system, specifically, a friction clutch. Background technique [0002] The clutch is responsible for the cut-off and combination of the power and the transmission system, so it can ensure the smooth start of the car when starting, the smooth shifting of gears, and prevent the transmission system from being overloaded. [0003] The clutch is used to cut and engage the power of the engine. The clutch is a transmission mechanism. It has an active part and a driven part. The two parts can be temporarily separated or slowly combined, and there may be relative rotation during the transmission process. Therefore, between the active part and the driven part of the clutch It will rely on contact friction to transmit torque, or use the pressing force required by friction to transmit torque. [0004] What is widely used in automobiles at present is exactly the f...
