Abstract
The utility model discloses a two-stroke cylinder block, which belongs to the technical of the gasoline engine. The utility model aims to provide a two-stroke cylinder block which has the advantages of simple structure, wear resistance, gas impermeability, good heat dispersion, long useful life and no environmental protection, which comprises a cylinder block, a black metal wear-resistant cylinder sleeve, a cooling plate, a fixed ring, a cylinder flange, a scavenging hole, a gas inlet and a gas outlet. The black metal wear-resistant cylinder sleeve is arranged in the cylinder block. The outside of the cylinder block is orderly provided with the cooling plate, the gas outlet, the gas inlet and the scavenging hole which are cast. The gas outlet, the gas inlet and the scavenging hole are cast with the external convex step of the black metal wear-resistant cylinder sleeve and the cylinder block to form a cylinder flange, an exhaust flange and an intake flange. The outside of the lower part of the black metal wear-resistant cylinder sleeve is provided with a recess to be built in the metal fixed ring and fixed with the cylinder flange in parallel. A fixed bolt is also arranged between the outside of the lower part of the black metal wear-resistant cylinder sleeve and the cylinder block.
Description
One, technical field:
The utility model relates to the technology of gasoline engine field, particularly relates to a kind of two-stroke cylinder block.
Two, background technique:
At present, two-stroke cylinder block of the prior art has two kinds of forms usually, a kind of is the full aluminium monomer structure of disposable casting, only chromium plating in cylinder body, meeting serious environment pollution when electroplating, it is wear-resisting poor with resistance to heat to electroplate cylinder liner, easy scuffing of cylinder bore, and working life is short.Another kind is full cast iron monomer structure pattern, and this cylinder liner Heavy Weight is wear-resisting, heat dispersion is poor.
Three, summary of the invention:
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of simple in structure, easy to make, wear-resisting, perfect heat-dissipating are provided, a kind of two-stroke cylinder block that long service life is free from environmental pollution.
The utility model is achieved in that by cylinder body, ferrous metal wear resisting cylinder jacket, radiating fin, retainer ring, cylinder body flange, transfer port, exhaust port, inlet hole to be formed; Described ferrous metal wear resisting cylinder jacket is assemblied in the cylinder body, and the cylinder body outside is provided with radiating fin, exhaust port, inlet hole, the transfer port structure of casting successively.The evagination step of described exhaust port, inlet hole, transfer port and ferrous metal wear resisting cylinder jacket, cylinder body casting be combined into cylinder body flange, exhaust flange, inlet flange.The outside, bottom of described ferrous metal wear resisting cylinder jacket is provided with groove and embeds metal retainer ring and cylinder body parallel flange secure bond.Be provided with fixing bolt between the outside, bottom of described ferrous metal wear resisting cylinder jacket and the cylinder body.
A kind of two-stroke cylinder block described in the utility model, have modern design, rational in infrastructure, preparation process is simple, wear-resisting property good, rapid heat dissipation, increased power, is difficult for the advantage of scuffing of cylinder bore, long service life.
Four, description of drawings:
Fig. 1 looks cross-sectional view for master of the present utility model
Fig. 2 is a backsight cross-sectional view of the present utility model
1, cylinder body 2, ferrous metal wear resisting cylinder jacket 3, radiating fin 4, retainer ring 5, cylinder body flange 6, transfer port 7, exhaust port 8, inlet hole 9, exhaust flange 10, inlet flange 11 grooves 12, fixing bolt 13 evagination steps
Five, embodiment:
In conjunction with the accompanying drawings the utility model is further specified.
The utility model is made up of cylinder body 1, ferrous metal wear resisting cylinder jacket 2, radiating fin 3, retainer ring 4, cylinder body flange 5, transfer port 6, exhaust port 7, inlet hole 8; The radiating fin 3 that described ferrous metal wear resisting cylinder jacket 2 is assemblied in the cylinder body 1 or direct pouring is provided with moulding successively in the mould in ferrous metal wear resisting cylinder jacket 2 outsides, exhaust port 7, inlet hole 8, transfer port 6 structures, adopt the low-pressure casting machine of full-automatic servo-control system to carry out low-pressure die casting, ferrous metal wear resisting cylinder jacket 2 and alloy casting liquid are connected as a single entity, after Cutter Body Processing with Machining Center form.The evagination step 13 of described exhaust port 7, inlet hole 8, transfer port 6 and ferrous metal wear resisting cylinder jacket 2, cylinder body 1 casting be combined into cylinder body flange 5, exhaust flange 9, inlet flange 10.The outside, bottom of described ferrous metal wear resisting cylinder jacket 2 is provided with groove 11 embedding metal retainer rings 4 and combines with cylinder body flange 5 secured in parallel; Can also be provided with fixing bolt 12 between the outside, the bottom of described ferrous metal wear resisting cylinder jacket 2 and cylinder body 1 fixes.The utility model tightness, good, the anti-cylinder bore deformation of wear-resisting property ability is strong, in light weight and thermal diffusivity is good, has advantages such as low cost of manufacture, casting quality is good, the life-span is long.
