A new type of automobile engine wind protection ring assembly

Abstract

The invention provides a novel wind ring assembly of an automobile engine. The novel wind ring assembly comprises a wind ring, and an open type pressing rivet structure is formed in the axle journal of the wind ring. The open type pressing rivet structure is stressed after a rubber ring is arranged into the open type pressing rivet structure, and an opening of the open type pressing rivet structure is contracted to clamp the rubber ring and the wind ring assembly is formed. The rubber ring is extended in the axial direction to form a horn mouth. A thickness sudden-change structure is arranged on the connecting section between an extended part of the rubber ring in the axial direction and a wind cover, and the rubber ring can be freely turned and folded. The opening angle alpha of the horn mouth is 10-50 degree. According to the novel wind ring assembly, the open type pressing rivet structure is formed in the axle journal of the wind ring, the open type pressing rivet structure is pressed after the rubber ring is arranged into the open type pressing rivet structure, and the opening of the open type pressing rivet structure is contracted to clamp the rubber ring and the wind ring assembly is formed, the rubber ring is extended in the axial direction to form the horn mouth, the thickness sudden-change structure is arranged on the connecting piece between the extended part of the rubber ring in the axial direction and the wind cover, and the rubber ring can be in the state of being freely turned and folded, so that the axial dimension, namely the total length, of the wind ring assembly is reduced.

Description

technical field [0001] The invention relates to a heat dissipation device for an automobile engine, in particular to a novel automobile engine wind protection ring assembly. Background technique [0002] The assembly diagram of the existing wind protection ring and related assembly parts is attached figure 1 , 2 shown. The windshield 1 is made of two materials, metal and plastic, and most of them are made of steel plate materials. The specific process is: blanking → rounding → shaping → welding → flanging → punching → trimming. Radiator windshield 5 adopts injection molding process to make mostly, is a plastic part. During the assembly process, first put the American throat clamps 2 and 4 (the clamps are standard parts with one-way sliding locking function) in the corresponding grooves of the sealing ring 3, and the clamps are in the "loose" state at this time. The small end of the sealing ring 3 (diameter) is placed on the wind protection ring 1. When the sealing ring 3...
