Description

Technical Field

[0001] The utility model belongs to the technical field of gasoline engine volutes, and in particular relates to a lightweight gasoline engine volute. Background Art

[0002] A gasoline engine includes a cylinder block, a cylinder head, a flywheel and a volute. The flywheel is located in the volute, and a number of fan blades are cast on the outward end of the flywheel. There are many cooling fins on the cylinder block and the cylinder head. When the flywheel rotates, the fan blades drive the air, generating a large air flow that blows along the volute toward the engine body to cool the engine body.

[0003] When the existing lightweight volute of a gasoline engine is installed and fixed to the gasoline engine, screws are generally passed through the mounting holes and the screw holes for screwing and fixing. However, since there is no connecting and docking structure between the lightweight volute of the gasoline engine and the gasoline engine during the installation process, it is difficult to accurately align the mounting holes and the screw holes. The screw holes can only be aligned by adjusting the position of the lightweight volute of the gasoline engine multiple times. For this reason, we propose a lightweight volute of a gasoline engine.

[0028] In this embodiment, preferably, the connecting assembly includes a connecting groove 100 symmetrically opened on the inner side of the heat dissipation cover mounting port 4 and a connecting block 101 symmetrically fixed on the surface of the gasoline engine turbine connecting seat 1. The connecting block 101 is snap-connected with the connecting groove 100, so that the lightweight volute 2 is conveniently connected to the gasoline engine turbine connecting seat 1.

[0029] In this embodiment, preferably, the guide assembly includes a guide groove 200 opened at the end of the connecting block 101 and a guide block 201 fixed inside the connecting groove 100. The guide block 201 is slidably connected to the guide groove 200, so that a guiding role can be played when the connecting block 101 is connected to the connecting groove 100.

[0030] In this embodiment, preferably, the limiting component includes limiting grooves 300 symmetrically opened on both sides of the connecting block 101 and built-in grooves 301 symmetrically opened on both sides of the inner wall of the connecting groove 100, and a limiting buckle 302 is arranged inside the built-in groove 301. The limiting buckle 302 is engaged with the limiting groove 300 through the locking connection with the limiting groove 300, so that the connecting block 101 can be temporarily limited inside the connecting groove 100.
