Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vibration damping discs, in particular to an anti-wear structure of a vibration damping disc. Background Art
[0002] The clutch is installed between the engine and transmission and is a component directly connected to the engine in the vehicle's drivetrain. Typically mounted alongside the flywheel assembly on the engine's crankshaft, the clutch is the component that disconnects and transmits power between the engine and the vehicle's drivetrain. It allows for gradual engagement between the engine and transmission, ensuring a smooth start; temporarily disconnects the engine and transmission to facilitate gear shifting and reduce shift shock; and, during emergency braking, acts as a disengagement mechanism to prevent overload in the transmission and other drivetrain systems, thus providing a degree of protection.
[0003] Usually, the torsional durability of the clutch driven plate assembly is 500w times. Each time the torsion damper spring is torsionally compressed, that is, it moves in the damper plate window. Conventional clutch design fails to take into account the actual movement trajectory of the damper spring, resulting in sliding friction between the damper spring and the window. After multiple sliding frictions, the damper spring and the damper plate window are worn, resulting in reduced strength and easy breakage. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the utility model provides an anti-wear structure for a vibration damping disc, which solves the problem that the vibration damping disc window does not match the movement trajectory of the vibration damping spring, causing the vibration damping spring and the vibration damping disc window to wear when the clutch driven disc assembly is used in the early stage, resulting in a reduction in their strength.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a vibration damping disc anti-wear structure, including a driven disc body, a notch groove is provided on the outer side of the surface of the driven disc body, a vibration damping disc window is provided on the surface of the driven disc body, and an opening groove is provided at the corner of the inner side of the vibration damping disc window, a through hole is provided on the surface of the driven disc body on the side of the vibration damping disc window, a connecting portion is provided on the driven disc body, a mounting hole is provided on the inner side of the connecting portion, a rivet hole is provided on the surface of the driven disc body located on the outer side of the connecting portion, and a limiting groove is provided on the surface inside the mounting hole.
[0006] Preferably, the notched grooves are distributed in a ring array, and heat sinks are provided in the notched grooves.
[0007] Preferably, the vibration damping disk windows are distributed in a ring array, one end of the vibration damping disk window is an arc-shaped edge, and the other end of the vibration damping disk window is a straight edge.
[0008] Preferably, the two ends of the arcuate edge are adapted to the open groove, and a flange is provided on the vibration damping disk window. The initial position of the shock-absorbing spring is at point d1, and the movement limit position of the shock-absorbing spring is at point d4. A circle is made with the distribution radius of the shock-absorbing spring as the size as c1, and a circular path of the movement limit is made in the same way as c2. The two ends c1 of the arcuate edge intersect, thereby reducing the sliding wear of the shock-absorbing spring and the edge of the vibration damping disk window during movement.
[0009] Preferably, the through holes correspond to the windows of the vibration damping disc one by one, and the through holes are formed from top to bottom through the body of the driven disc.
[0010] Preferably, one end of the rivet hole is designed as a trumpet-shaped structure, and the rivet holes are distributed in a ring array.
[0011] Preferably, the limiting grooves correspond to the windows of the vibration damping disc one by one, and the inner side of the limiting grooves is designed to be an arc-shaped structure.
[0012] The utility model provides a wear-resistant structure for a vibration damping disc. Compared with the prior art, it has the following beneficial effects:
[0013] The anti-wear structure of the vibration damping disc is provided with arc-shaped edges, through holes and mounting holes. When designing the arc-shaped edges, the curvature of the arc-shaped edges is increased, thereby reducing the friction formed on the side of the vibration damping disc window during the movement of the vibration damping spring, reducing the sliding wear generated, and forming an open structure with open grooves to reduce the collision between the vibration damping spring and the corners, reducing the wear area, and increasing the heat dissipation effect through multiple heat sinks.
