Abstract

The invention relates to the field of machine building, concerns engine construction and can be used in crank-and-rod mechanisms of internal combustion engines. The purpose of the invention is to increase reliability by reducing the operating voltages and eliminating voltage concentrators. Between the plates (P) 7 and 8 there is a power element in the form of a cryoshrinkage divided into a plane of separable (L S l XI CJ x XI

The connecting rod is made of a rod 1 with a piston 4i.ni 7 and a crank 3 heads, a lid of a lam elamen. Opple of fastening, consisting of a screw- and a pressure screw 6. The rod 1 consists of two external parts in the form of plates 7 and 8, Imprinted from laminated material, such as using dopo-transverse reinforcement with a unidirectional composite material with an equal volume ratio of layers.

implies a reduction in the effective stresses when exposed to workloads.

1c (the same happens to the leveling of the stresses in the zone of connection of the lid with the rod due to a more uniform application of the load from the side of the bracket. In addition, the side faces of the bracket have a reinforcing back rest on the elements covered by it, which is important when using a composite material Formula, in general, with lower shear limit characteristics.
