Problems solved by technology
[0003] In the conventional method, in many cases, the water pump for circulating the coolant along the coolant circulation system is integrally mounted on the cylinder block, with the water pump accommodation chamber in a recess in the side wall at one end of the cylinder block , the pump chamber should try to be formed in the cylinder body, and the recessed part constituting the pump chamber should be formed at a position that does not interfere with the cylinder, water jacket, crankcase, etc. provided in the outer wall portion of the cylinder block, which makes the pump chamber near the The structure of the inner wall parts of the cylinder becomes complicated, which increases the risk of shrinkage cavities in the cylinder block material during the die casting process, resulting in an increased failure rate
[0004] In particular, when casting the cylinder block, it is difficult to ensure the accuracy of the pump chamber, and therefore, it is necessary to ensure the accuracy of the pump chamber by cutting the recessed portion after its die-casting, thus, many machining man-hours are added, resulting in an increase in cost
[0005] In addition, in the traditional design, the function of the water pump support is single, it is only used to accommodate the thermostat and install the engine water inlet, and other structures such as the cylinder water jacket water inlet, water outlet, water pump volute, etc. The parts and structures are scattered, and there are many connecting pipelines. For the current small engines with increasingly compact structures, the layout design becomes more difficult; at the same time, it will increase a lot of assembly man-hours and affect the production cycle.

The invention provides a water pump support where a water pump volute is integrated. The water pump support comprises the water pump volute, a cylinder body water jacket water inflow channel, a thermoregulator accommodating chamber and a cylinder body water jacket water outflow channel. The water pump support further comprises an A steel pipe integrated on the water pump support, a B steel pipe, a C steel pipe and lug parts which are located on the outer edge of the water pump volute and are distributed in a radial mode. The water pump volute is integrated on the water pump support, cylinder casting difficulty is reduced, machining does not need to be performed on the side of a cylinder body, and the reject ratio and increase of cost can be controlled. Connecting lines are fewer, the water pump support is convenient to arrange and compact in structure and integrates various functions, the problem of difficulty in arrangement of a small supercharge direct injection gasoline engine at present is solved, assembling working hours can be reduced simultaneously, and takt time is met.
Description
technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a water pump support integrated with a water pump volute. Background technique [0002] In the engine, by continuously circulating the coolant along the coolant circulation system including the water jacket in its cylinder block and cylinder head, the engine block can be kept at the proper temperature to ensure the durability of various parts . [0003] In the conventional method, in many cases, the water pump for circulating the coolant along the coolant circulation system is integrally mounted on the cylinder block, with the water pump accommodation chamber in a recess in the side wall at one end of the cylinder block , the pump chamber should try to be formed in the cylinder body, and the recessed part constituting the pump chamber should be formed at a position that does not interfere with the cylinder, water jacket, crankcase, etc. provided i...
