Example Embodiment

[0020] The technical solutions of the present invention are further described in detail below through the examples.

[0021] see figure 1 , figure 2 , In this embodiment, a spring combination disc includes a circular-shaped lower thrust ring and a circular-shaped upper thrust ring, and the upper and lower thrust rings are both stretched and formed by thin plate materials. There are 28 lower spring seats 31 in the lower thrust ring 3 and 28 upper spring seats 41 in the upper thrust ring 4, such as image 3 As shown, a spring is provided between the lower spring seat 31 and the upper spring seat 41, and the centerlines of the upper spring seat 41 and the lower spring seat 31 coincide.

[0022] The springs are divided into left-handed spring 2 and right-handed spring 1. On the upper spring seat 41 and the lower spring seat 31 of the upper and lower thrust rings, left-handed spring 2 and right-handed spring 1 are arranged at intervals, that is, install one left-handed spring 2 ...

Abstract

The invention relates to an auto part technology, in particular to a spring composite disc. The spring composite disc solves the unsafe problems that an automobile clutch spring composite disc is notreasonable in structure, and consequently springs are staggered and fall and a foundation frame deforms. The spring composite disc comprises upper and lower thrust rings in ring shapes, a plurality oflower spring bases are arranged in the lower thrust ring, a plurality of upper spring bases are arranged in the upper thrust ring, springs are arranged between the lower spring bases and the upper spring bases, the quantity of the lower spring bases is the same as that of the upper spring bases, the quantity is an even number, and center lines of the lower spring bases and the upper spring basesare coincident; and the springs comprise the left-hand springs and the right-hand springs, and the left-hand springs and the right-hand springs are arranged in a spaced manner. The springs comprise the left-hand springs and the right-hand springs, it is guaranteed that the composite disc cannot twist or incline in the compressed process, the lower spring bases and the upper spring bases directly conduct expansive interference fit assembly on the left and right springs under the effect of a special compression device, the springs and the thrust rings are completely combined into a whole, and the good structure strength is achieved.

Description

technical field [0001] The invention relates to the technology of auto parts, in particular to a spring combination disc used on a clutch. Background technique [0002] At present, the clutches of automobiles, machine tools and other mechanical equipment are basically inseparable from springs. The thrust ring of the spring combination disc in the clutch has poor positioning accuracy for the spring and is easy to loosen, resulting in poor sensitivity and potential safety hazards. In practical applications, the spring combination disc is mainly designed according to its required functions. For example, the Chinese patent application number is 200710168634.8, which is an auto part of an arc-shaped spring damping flywheel assembly. Auxiliary flywheel, the center of the auxiliary flywheel is provided with a disk core with a disc hub, and the upper and lower vibration damping discs are used to connect the auxiliary flywheel and the disc core, and there are 2-4 discs on the hub of...
