Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment, and its content is explanation of the present invention rather than limitation:

[0039] Such as Figure 2~4 , the flexible windshield of the present invention includes a composite supporting steel plate 1 and flexible rubber 2, which can be bonded by vulcanization, thermal bonding or glue, preferably vulcanization bonding, and the peel strength is greater than 7kN / m, ensuring that the rubber and the steel plate The connection is firm and will not fall off.

[0040] Such as Figure 5 , Image 6 The side of the supporting steel plate 1 in contact with the flexible rubber 2 is provided with a number of peak-shaped protrusions 1-1, and the other side is provided with a number of through holes 1-2 and a number of gaps 1-3 according to the structure of the cooling module 4, including the upper water pipe The gaps, the mounting holes for the deg...

Abstract

The invention discloses a flexible wind shield, and belongs to the technical field of heavy-duty car part manufacturing. A supporting steel plate and the flexible rubber are compounded into a whole, the flexible rubber in contact with the cab floor is matched with the cab floor in shape, gaps of the cab floor are shielded, and air leakage is reduced; the supporting steel plate in contact with thecooling module is provided with a plurality of through holes or notches for various pipelines and other structures to penetrate through according to the structure of the cooling module, so that the gap between the flexible wind deflector and the cooling module is greatly reduced, the hot air backflow prevention effect is good, and the heat dissipation efficiency of the cooling module is improved.Peak-shaped protrusions on the supporting steel plate increase the combination area of the supporting steel plate and the flexible rubber, and the combination strength is improved. The wrinkled protrusions and the annular grooves are formed in the flexible rubber, before the cab does not bounce, the upper portion of the flexible rubber and the floor of the cab are sealed, hot air backflow is prevented, and after the cab bounces, the flexible rubber and the cab can still be well sealed through compression and springback deformation.

Description

technical field [0001] The invention belongs to the technical field of heavy-duty automobile parts manufacturing, and in particular relates to a flexible windshield. Background technique [0002] The upgrade of automobile emission standards and the user's demand for high-horsepower engines have put forward higher requirements for the cooling system of heavy-duty vehicles. The hot air backflow phenomenon of heavy-duty vehicles means that after the cold air passes through the intercooler and radiator, the temperature of the cold air rises and turns into hot air. This phenomenon of intercooler and radiator core. The recirculation of hot air will reduce the heat dissipation capacity of the intercooler and radiator, affecting the performance of the cooling system. [0003] When designing, a gap needs to be reserved between the cab floor and the cooling module to ensure that the cab will not collide with or rub against the chassis when the cab jumps up and down, left and right, ...
