SPRING PLATE OF COMBINED PROFILE (VERSIONS) AND SPRING (VERSIONS) USING SPRING PLATE Russian patent published in 2011 - IPC F16F1/18 

FIELD: machine building.

SUBSTANCE: spring plate of combined profile has thick central part with central platform, thin end parts of continuous profile and working parts positioned between central and end parts. The working parts are made out of combination of parts of continuous profile adjacent to the central part and of parts of alternate profile adjacent to the end parts. Distance between their dividing cross sections on both arms of the plate is equal to working length of the following spring of a short plate in a package. According to the second version an additional distinguished feature of the spring plate is like follows: working parts of continuous profile adjacent to the central part have thickness equal to thickness of the central part. The combined spring has several spring plates. Also, the root plate has a combined profile, while the last plate has an alternate profile. The spring plates contact each other along projection of the central platform and ends of the last plate of alternate profile. Thickness of the central part of the plate of combined profile is equal to thickness of the last plate of alternate profile. Few-plates trapezoidal spring consists of a package of overlaid plates of combined profile with step-by-step decreasing working length and of a following plate of alternate profile. All plates contact each other along whole plane of contact. A combined two-step spring includes a main spring and an additional spring set in a lower position. The main spring consists of plates of similar combined profile where distance between cross sections dividing working parts of continuous and alternate profile on both arms of the plate is equal to working length of the additional spring.

EFFECT: raised efficiency of metal use.
