Abstract
The utility model aims to provide a front suspension assembly master cylinder which solves the problem of high workpiece assembly difficulty in the prior art. The front suspension assembly master cylinder provided by the utility model is characterized in that the cylinder sleeve is tubular, a cylinder barrel is sheathed outside the cylinder sleeve, a piston rod is sheathed in the cylinder sleeve, and the upper end of the cylinder sleeve is provided with an upper cover. The tubular cylinder sleeve, the cylinder barrel and the upper cover are processed separately; when assembling, the cylinder sleeve, the cylinder barrel and the seal seat are subjected to sheathing assembly, and then, the piston rod, the upper cover and other components are assembled; and since the cylinder sleeve is simply tubular, the cylinder is convenient for processing, and the assembling flexibility is greatly enhanced.
Description
Technical field
The utility model relates to a kind of master cylinder of preceding oleo-pneumatic suspension assembly.
Background technique
In typical master cylinder, the direct socket of piston rod and cylinder barrel.Because piston rod head will slide in cylinder barrel, tolerance of size, morpheme worker's difference and roughness requirement round in the cylinder barrel are high, are difficult to processing, and the assembling difficulty of workpiece is bigger.
The model utility content
The utility model is intended to provide a kind of forward mounting assembly master cylinder, to solve the big problem of workpiece assembling difficulty in the existing technology.
The purpose of the utility model can reach through following measure: the forward mounting assembly master cylinder in this programme, and it is characterized in that: cylinder sleeve is tubular, and cylinder sleeve is socketed with cylinder barrel outward, is socketed with piston rod in the cylinder sleeve, and the upper end of cylinder sleeve is provided with loam cake.
The cylinder sleeve of tubular, cylinder barrel, upward cover split-type processing; When assembling, earlier cylinder sleeve and cylinder barrel, sealing seat are carried out the socket assembling; Further carry out the assembling of parts such as piston rod, loam cake again; Because cylinder sleeve is a simple tubular, not only easy to process, the flexibility of assembling also is greatly improved.And this scheme has changed the inner force structure of cylinder barrel; The head of piston rod in the past acts directly on the inner place of cylinder sleeve; The active force that piston rod head brings in this programme passes through the cylinder sleeve peptizaiton of tubular in the cylinder barrel inwall, has avoided stressed in the past concentrated situation, the life-span of having improved whole assembly; Even if impaired also being easy to of cylinder sleeve changed, the cost of replacing also reduced more greatly.
Further: the outer wall of cylinder sleeve upper end is provided with the cylinder sleeve circular groove; Be provided with O shape circle in the cylinder sleeve circular groove; Be provided with sealing seat in the cylinder barrel, sealing seat and cylinder sleeve socket-connect, and the lower end of cylinder sleeve fixes between cylinder barrel and sealing seat; The face of sealing seat and cylinder sleeve socket is provided with the sealing seat circular groove, is provided with O shape circle in the sealing seat circular groove.
Further: loam cake is connected with cylinder barrel, is provided with inner convex platform in the loam cake, and the upper end of cylinder sleeve fixes between cylinder barrel and inner convex platform.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the utility model embodiment's a schematic representation.
Embodiment
Known concrete structure and characteristic are no longer set forth at this in the following proposal.As shown in Figure 1: be socketed with cylinder barrel 2 outside the cylinder sleeve 3 of forward mounting assembly master cylinder, be socketed with piston rod 1 in the cylinder sleeve 3, the upper end of cylinder sleeve 3 is provided with loam cake 4, and cylinder sleeve 3 is tubular.
The outer wall of cylinder sleeve 3 upper ends is provided with two cylinder sleeve circular grooves; Be provided with O shape circle in the cylinder sleeve circular groove; Cylinder barrel 2 internal fixation have sealing seat 21, and sealing seat 21 socket-connects with cylinder sleeve 3, and the lower end of cylinder sleeve 3 fixes between cylinder barrel 2 and sealing seat 21; Sealing seat 21 is provided with the sealing seat circular groove with the face of cylinder sleeve 3 sockets, is provided with O shape circle in the sealing seat circular groove.Loam cake 4 and cylinder barrel 2 are connected through bolt, are provided with inner convex platform 41 in the loam cake 4, and the upper end of cylinder sleeve 3 fixes between cylinder barrel 2 and inner convex platform 41, can know that so far cylinder sleeve 3 is by stable being fixed in the cylinder barrel 2.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
