Description

Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to a vibration-resistant and stable clutch cover assembly. Background Art

[0002] The traditional clutch cover assembly usually includes an outer shell, a diaphragm spring, a transmission plate and a pressure plate. The outer periphery of the outer shell is connected to the pressure plate through the transmission plate, and the axial movement of the pressure plate is controlled by the diaphragm spring arranged between the outer shell and the pressure plate. The explosion-proof clutch cover assembly replaces the diaphragm spring with a lever structure, so that the clutch has an explosion-proof function and its structure is more stable and reliable. However, the weight distribution of the explosion-proof clutch cover assembly is uneven, and it is prone to shaking and loud noise, which seriously affects the service life of the clutch. Summary of the Invention

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the utility model is: a vibration-resistant and stable clutch cover assembly, including an outer shell, an adjusting seat, a pressure plate, a release rod, a gasket, a torsion spring, a spring and a transmission plate. The outer shell is provided with an adjusting seat distributed in a circumferential manner. The adjusting seat is rotatably connected to a release rod for controlling the movement of the pressure plate. The release rod is clamped with a gasket, and the release rod is connected to a torsion spring for clamping the gasket. The pressure plate is coaxially distributed on the outer shell through the release rod. A spring for controlling the reset of the pressure plate is provided between the pressure plate and the outer shell. The pressure plate is connected to the outer shell through a transmission plate, and the inner side of the pressure plate is provided with counterweight holes distributed in a circumferential manner.

[0004] By adopting the above technical solution, a balancing hole for an external balancing screw is provided on the inner side of the pressure plate. By installing or removing the balancing screw at the balancing hole in different positions, the weight of the clutch cover assembly is evenly distributed, so that the clutch cover assembly rotates smoothly with low noise. The balancing hole is a blind hole with a thread. When the clutch cover assembly rotates with the flywheel, the bottom surface of the balancing hole can offset the centrifugal force of the balancing screw, prevent the screw from detaching, and improve the stability of the assembly during rotation.

[0005] The utility model is further configured as follows: the adjustment seat includes a stud, a nut seat and a locking plate, one end of the stud is pin-connected to the separation rod, and the other end is threadedly connected to the nut seat, the outer shell is provided with a first threaded hole and a countersunk hole, the locking plate is threadedly connected to the outer shell through the first threaded hole, and the nut seat is clamped between the countersunk hole and the locking plate.

[0006] By adopting the above technical solution, the distance between the pressure plate and the housing is adjusted by rotating the nut seat, so that the pressure plate is parallel to the downstream friction plate, effectively compensating for the installation error of the clutch cover assembly.

[0007] The utility model is further configured such that the torsion spring includes a snap portion, and a force arm portion and a coil portion symmetrically distributed on both sides of the snap portion; the gasket is provided with a snap connection portion distributed in a circumferential manner, one side of the snap connection portion is snapped with the snap portion, and the other side abuts against the separation rod; the coil portion is connected to both sides of the separation rod through a pin, and the force arm portion abuts against the outer shell.

[0008] By adopting the above technical solution, when the clutch pedal is pressed, the rotation of the release rod is controlled by the gasket, thereby driving the pressure plate to move toward the direction of the outer shell. The gasket is tightly pressed against the release rod by the torsion spring on all sides to prevent the gasket from separating from the release rod. The torsion spring is arranged on both sides of the release rod through the coil part, so that the torsion spring is evenly stressed when deformed. Its structure is stable and easy to install.

[0009] The utility model is further configured such that the pressure plate is provided with a steering portion and a transmission portion distributed in a circular pattern, the separation lever is rotatably connected to the pressure plate through the steering portion, the outer side of the outer shell is provided with mounting holes distributed in a circular pattern, the pressure plate is provided with a second threaded hole, one end of the transmission plate is riveted to the outer shell through the mounting hole, and the other end is threadedly connected to the pressure plate through the second threaded hole.

[0010] Furthermore, the housing is provided with a reserved hole corresponding to the second threaded hole.

[0011] Using the above technical solution, the pressure plate is provided with four pairs of staggered steering parts and transmission parts. The steering part is provided with a hole corresponding to the separation rod. The separation rod is rotatably connected to the steering part through a pin and a retaining spring. When installing the pressure plate, the screw is passed through the reserved hole to thread the transmission plate and the transmission part. When the pressure plate moves axially toward the direction of the outer shell, the transmission plate is deformed, so that the pressure plate maintains a stable moving state.

[0012] The utility model is further configured such that the pressure plate is provided with boss portions distributed in a circumferential manner, the housing is provided with a snap ring portion corresponding to the boss portions, and both ends of the spring are respectively sleeved on the boss portions and the snap ring portions.

[0013] By adopting the above technical solution, the spring is clamped between the housing and the pressure plate through the boss portion and the clamping ring portion structure, without the need for other fasteners to assist in fixing, thus reducing assembly steps and improving production efficiency.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The inner side of the pressure plate is provided with a counterweight hole for connecting an external counterweight screw.
