Abstract
The utility model discloses a transmission cylinder, which mainly comprises a piston rod, an aluminum alloy cylinder body and a piston. Since the cylinder body is cast by aluminum alloy, the weight is reduced and the transmission cylinder is not apt to be rusted; since an embedded cylinder barrel structure is used in the cylinder body, the cylinder body is simple to manufacture; and since sealing rings are arranged in the aluminum alloy cylinder body and the piston, the sealing rings are not apt to be worn and the service life of the sealing rings is prolonged.
Description
Technical field
The utility model relates to a kind of auto parts and components, especially a kind of speed changer cylinder.
Background technique
Like product is of a great variety in the market, and cast iron is material but its cylinder body all is employing basically, and Heavy Weight easily gets rusty, and cylinder body employing monolithic construction, and difficulty of processing is big, and seal ring is easy to damage, and working life is short.
The model utility content
At the deficiencies in the prior art, it is a kind of in light weight that the purpose of this utility model is to provide, and processing is simple, the speed changer cylinder of long service life.
The utility model adopts following technological scheme to realize its purpose: a kind of speed changer cylinder, comprise piston rod, aluminium alloy cylinder and piston, wherein piston rod inserts in the aluminium alloy cylinder and is fixed together by compound nut and piston, upper cover of piston rod has piston rod O type circle and the little O type of piston rod circle, and piston rod O type circle is positioned at the inside of cylinder body, the little O type of piston rod circle is positioned at the inside of piston, be with piston O type circle on the piston, piston and aluminium alloy cylinder cooperatively interact by supporting ring, piston is positioned at the cylinder barrel of aluminium alloy cylinder, there is cylinder cap the aluminium alloy cylinder back by screw, aluminium alloy cylinder top is provided with odd-side low gear pore, and the cylinder cap bottom is provided with odd-side high gear pore.
The beneficial effect that the technological scheme that adopts the utility model to provide can reach is: cylinder body adopts aluminium alloy compression casting, weight reduction, be difficult for getting rusty, cylinder interior adopts and embeds the cylinder type structure, processing is simple, seal ring is arranged on aluminium alloy cylinder and internal piston, and is not easy to wear, makes prolong working life.
