Abstract

The invention relates to a wind shield which comprises a wind shield body made of PP materials. The wind shield body adopts an integral injection molding one-step forming technology and comprises a wind shield ring, the wind shield ring comprises an inner ring and an outer ring, the inner ring is shorter than that of the outer ring, the inner ring and the outer ring are combined to form a C-shapedgroove, and an engine fan ring is arranged in the middle of the C-shaped groove. According to the wind shield, integral injection molding one-step forming is carried out without secondary processing,the production efficiency is high, the product consistency is good, the size precision is high, and the structure is reliable; the matching position of the wind shield and an engine fan is designed into a C-shaped structure, so that the air quantity loss is reduced; and the problems of large air loss and poor assembly process of a traditional wind shield are solved, and the effective supply air rate and production efficiency are improved.

Description

technical field [0001] The invention relates to the field of heavy-duty automobile parts manufacturing, and more particularly, relates to a plastic windshield mainly used in a novel mounting structure between a commercial automobile radiator and an engine fan. Background technique [0002] With the upgrading of global automobile emission standards, the demand for horsepower and torque of heavy-duty vehicles in the domestic market continues to increase. Compared with national V and national VI high-efficiency SCR engines, the heat transferred to the coolant by national VI EGR engines increases by 20% to 25%. The system puts forward strict requirements. The ability of the cooling system mainly depends on factors such as the performance of the radiator, the flow rate of the coolant, and the effective air volume provided by the engine fan. The performance of the fan shield directly determines the amount of air passing through the radiator, which has an important impact on the h...
