Abstract
The utility model discloses an improved seal ring assembling structure installed on two ends of a vehicle hydraulic steering gear oil cylinder. The seal rings (1) of the seal ring structure are arranged on the end surfaces of cylindrical shell supporting parts (7) positioned on two ends of the oil cylinder; the seal rings (1) are fixedly arranged on the end surfaces of the shell supporting parts (7) by annular fixed parts (2); an annular boss is formed on the contact surfaces of each annular fixed part (2) and each seal ring (1); the annular boss is pressed into the seal ring (1) to be in interference fit with the seal ring (1). The improved seal ring assembling structure is characterized in that fixed convex ribs (4) are formed on an inner installing wall surface; the fixed convex rib (4) and a stop surface (6) on the other side form a bulge which is embedded into the seal ring (1) by an installing surface (5) facing to the pressing-in direction of the seal ring (1). According to the improved seal ring assembling structure disclosed by the utility model, the purpose of fixing the seal ring position is realized, the advantage of simple structure is kept, and cost is effectively controlled.
Description
Technical field
The utility model relates to Manufacturing Technology for Automotive Parts field, and specifically, the utility model relates to a kind of mounting structure of seal ring.The mounting structure of described seal ring needs for the sealing assembling at hydraulic steering gear oil cylinder two ends.
Background technology
Hydraulic steering gear oil cylinder two ends at automobile need fitting tight circle, to realize oil pressure sealing.During fitting tight circle, need in support part, process seal ring internal face is installed, seal ring is pressed into wherein, making seal ring and internal face is interference fit.Now, for preventing from scratching seal ring surface, internal face has higher roughness requirement, requires smoother.But, in actual production, find, due to the resilience of seal ring, seal ring likely can get loose from internal face.
Utility model content
Technical problem to be solved in the utility model is how from designing, thoroughly to prevent that seal ring from departing from installation site, meanwhile, do not increase again manufacture difficulty and manufacturing cost.
In order to address the above problem, the technical solution of the utility model is as follows:
A kind of ring structure that is arranged on hydraulic steering device of vehicle oil cylinder two ends, the seal ring of described ring structure is arranged at the end face of the housings support portion that is positioned at oil cylinder two ends, tubular, described seal ring is fixed on the end face of described housings support portion with ring-type connecting element, the contact surface of described ring-type connecting element and described seal ring is formed with annular boss, described annular boss is pressed in described seal ring and forms interference fit with described seal ring, described annular boss is installation internal face towards the face of oil cylinder axis, it is characterized in that
On described installation internal face, be formed with fixedly fin, described fixedly fin forms the described seal ring of projection embedding to be pressed into the attachment face of direction towards seal ring with the stop surface that is positioned at opposite side.
Thus, can be after seal ring be pressed into, with the position that fixedly fin limits seal ring.
According to a kind of ring structure that is arranged on hydraulic steering device of vehicle oil cylinder two ends of the present utility model, preferably, the angle of described attachment face and described stop surface is acute angle.
According to a kind of ring structure that is arranged on hydraulic steering device of vehicle oil cylinder two ends of the present utility model, preferably, described stop surface is perpendicular to described installation internal face.
Thus, can effectively utilize stop surface carries out spacing to seal ring.
According to the utility model, to compare with conventional smooth inner wall face, its beneficial effect is: adopt the internal face after improving, utilized the crowded effect of rising of rubber, realized the object of curing seal ring position; By actual production, verify, effectively reliable; On the other hand, still retain on the whole the simple advantage of structure, become instinct to be controlled effectively.
Accompanying drawing explanation:
Fig. 1 is seal ring mounting structure figure
Fig. 2 is the conventional smooth inner wall face of strut member schematic diagram,
Fig. 3 is that strut member improves internal face schematic diagram.
In figure, 1 is the seal ring at hydraulic steering device of vehicle oil cylinder two ends, and 2 is annular fixing member, and 3 for internal face is installed, and 4 is fixing fin, and 5 is attachment face, and 6 is stop surface, and 7 is housings support portion.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail.
Embodiment
A kind of ring structure that is arranged on hydraulic steering device of vehicle oil cylinder two ends, described ring structure is installed on the housings support end surface that is formed at oil cylinder two ends, with annular fixing member, fix, described annular fixing member one side is formed with annular boss, described annular boss is pressed in described seal ring and forms interference fit, and described annular boss is installation internal face towards the face of oil cylinder axis.
On described installation internal face, be formed with fixedly fin, described fixedly fin forms the described seal ring of projection embedding to be pressed into the attachment face of direction towards seal ring with the stop surface that is positioned at opposite side, described stop surface is perpendicular to described installation internal face, and the angle of described attachment face and described stop surface is acute angle.
Installation process is as follows: first seal ring is pressed into circular step, seal ring is because install the bossing compression on inclined-plane, and when seal ring is pressed into behind desired location, due to the elasticity of rubber, the rubber of compression is clamp-oned in the space at stop surface rear portion; Because stop surface face is vertical with installation internal face, stop surface plays the effect of hangnail, thereby has limited the resilience of seal ring, prevents that it from coming off from internal face is installed.
Compare with conventional smooth inner wall face, adopt the internal face after improving, utilized the crowded effect of rising of rubber, realized the object of curing seal ring position; By actual production, verify, effectively reliable; On the other hand, still retain on the whole the simple advantage of structure, become instinct to be controlled effectively.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification sheets, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by claims and equivalent thereof.
