Problems solved by technology

However, the function of the existing water pump backing plate is relatively single, resulting in many special parts, which cannot meet the needs of different complete vehicles, and increases the cost; In the same plane, but the installation position of the water pump backing plate is not only on the outer surface of the cylinder head, but also on the outer surface of the cylinder, resulting in deformation of the installation plane of the water pump backing plate due to installation stress, shortening its service life

Embodiment 1

[0028] The specific embodiments of the present invention are as Figure 1 to Figure 3 Shown is a water pump backing plate. The backing plate body is fixed on one side of the engine body by 4 M8 bolts. It includes a water pump mounting plate 1 for installing the water pump. The backing plate body on the side of the water pump mounting plate 1 is also A fan mounting plate 2 is provided for installing a fan. This type of arrangement can reduce the special parts used when installing the engine while ensuring the rationality of the arrangement of parts and save costs.

[0029] The side of the backing plate body of the water pump backing plate that is in contact with the engine cylinder head and cylinder block is provided with a step surface 8 that makes the upper and lower parts of the backing plate not coplanar. The lower part of the backing plate near the water inlet of the engine body is the base surface; Two adjusting screw holes 5 are arranged on the upper part of the backing pla...

Abstract

The invention discloses a water pump cushioning board. The water pump cushioning board comprises a cushioning board body used for installing a water pump on an engine body. The cushioning board body is provided with a water pump installation plate, and a fan installation plate is arranged at the part, on one side of the water pump installation plate, of the cushioning board body. The water pump cushioning board is light in mass, high in strength and good in universality, can be used for installing the water pump and a fan assembly, guarantees the arrangement reasonability of the water pump and the fan assembly and reduces the number of special parts for installing an engine assembly, and installation stress exerted on installation planes of the water pump cushioning board and the engine body is small.

Description

Technical field [0001] The invention relates to the field of engine cooling system installation, in particular to a water pump backing plate. Background technique [0002] The main function of the water pump backing plate is to fix and support the water pump on the body, ensure the water circulation between the water pump and the body, and ensure the coplanarity of the wheel groove of the water pump wheel and the front gear train of the entire engine in terms of size. However, the function of the existing water pump backing plate is relatively single, resulting in more special parts, and cannot meet the needs of different complete vehicles, which increases the cost; after the engine is installed, the outer surface of the cylinder head and the cylinder block on the same side is not necessarily In the same plane, and the installation position of the water pump backing plate is both on the outer surface of the cylinder head and the outer surface of the cylinder body, which causes th...
