Embodiment Construction

[0020] The technical solutions of the present invention will be further specifically described below through examples.

[0021] see figure 1 , figure 2 , the present embodiment is a combination spring disc, including a ring-shaped lower thrust ring and a ring-shaped upper thrust ring, and the upper and lower thrust rings are stretched and formed by thin plate materials. Be provided with 28 lower spring seats 31 in the lower thrust ring 3, be provided with 28 upper spring seats 41 in the upper thrust ring 4, as image 3 As shown, a spring is arranged 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] Springs are divided into left-handed spring 2 and right-handed spring 1. On the upper spring seat 41 and 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, one left-handed spring 2 an...

Abstract

The invention relates to the technology of automobile parts, in particular to a spring combined disk, solving the problems that the spring is staggered and falls off, a base frame is deformed and the like caused by unreasonable structure of a spring combined disk of an automobile clutch. The spring combined disk comprises an annular upper and an annular lower push rings, wherein the lower push ring is internally provided with a plurality of lower spring seats; the upper push ring is internally provided with a plurality of upper spring seats; springs are arranged between the upper spring seatsand the lower spring seats; the number of the lower spring seats is equal to the number of the upper spring seats and is an even number; center lines of the lower spring seats and the upper spring seats are superposed; and the springs comprise left-handed springs and right-handed springs which are arrayed at intervals. Since the springs comprise the left-handed springs and the right-handed springs, the combined disk cannot be twisted and tilted in the compressed process; the lower spring sets and the upper spring seats directly carry out expansible interference fit assembly on the left-handedsprings and the right-handed springs, so that the springs and the push rings are completely combined into a whole; and the invention has favorable structural strength.

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...
