Description
Technical field
The utility model relates to a kind of oil seal of resistance to ATF circle, belongs to rubber seal field.
Background technique
The market of automatic transmission in recent years annual all with 20% speed increment, but China's starting evening after all, weak foundation, a large amount of automatic transmission still dependence on import.Some new products of independent brand enterprise development, but majority does not form industrialization.Seal ring is the important composition parts of Hydraulic Power Transmission System in automatic transmission, plays sealing fluid force feed in oil hydraulic cylinder reciprocatory movement, keeps oil pressure effect.And existing seal ring due to structural design unreasonable, in use have that cost is high, the inconvenience of complex structure, fitting operation, not wear-resisting and lower temperature resistance is poor, and there is the problem of leakage of oil in oil hydraulic cylinder repeatedly movement process.
Summary of the invention
The purpose of this utility model is to provide a kind of novel to-and-fro motion oil seal of resistance to ATF circle, with solve existing seal ring due to structural design unreasonable, in use have that cost is high, the inconvenience of complex structure, fitting operation, not wear-resisting and lower temperature resistance is poor, and there is the problem of leakage of oil in oil hydraulic cylinder repeatedly movement process.
Described ATF oil is automatic transmission hydraulic oil.
The utility model solves the technological scheme that its technical problem adopts:
A kind of novel to-and-fro motion resistance to ATF oil rubber seal, comprise rubber seal matrix, the inner peripheral surface diameter of the rubber seal matrix described in setting is a, wall thickness is d, rubber seal matrix thickness is c, the inner peripheral surface diameter of pilot hole is A, the outer peripheral surface diameter of pilot hole is D, the height of pilot hole is C, the then inner peripheral surface diameter a=A+d/a+d=1.0 ~ 1.1 of rubber seal matrix, wall thickness d={d-0.5 × (the D-A)/d}=0.1 ~ 0.3 of rubber seal matrix, the thickness c=C-0.1 ~ C-1 of rubber seal matrix.
The beneficial effects of the utility model are:
The oil seal of resistance to ATF coil structures of the present utility model is reasonable in design, and owing to setting rational technical parameter, as the thickness of the inner peripheral surface diameter of rubber seal matrix, the wall thickness of rubber seal matrix and rubber seal matrix, make this rubber seal matrix have good high temperature resistant, wear-resisting and resistance to ATF oiliness energy, guarantee that this rubber seal matrix keeps good sealing effect in to-and-fro motion repeatedly.
Accompanying drawing explanation

Fig. 2 is the partial sectional view of the pilot hole for rubber seal shown in erection drawing 1;
Fig. 3 is the main sectional view of the novel to-and-fro motion oil seal of resistance to ATF circle of the present utility model, and wherein the inner peripheral surface of rubber seal matrix is the arc surface that middle part is inwardly given prominence to, and the outer peripheral surface of rubber seal matrix is cylndrical surface;
Fig. 4 is the partial sectional view of the pilot hole for rubber seal shown in erection drawing 3.
Embodiment
A kind of novel to-and-fro motion resistance to ATF oil rubber seal as shown in Figure 1 to 4, comprise rubber seal matrix 1, it is characterized in that: the inner peripheral surface diameter of the rubber seal matrix 1 described in setting is a, wall thickness is d, rubber seal matrix 1 thickness is c, the inner peripheral surface diameter of pilot hole 2 is A, the outer peripheral surface diameter of pilot hole 2 is D, the height of pilot hole 2 is C, the then inner peripheral surface diameter a=A+d/a+d=1.0 ~ 1.1 of rubber seal matrix 1, wall thickness d={d-0.5 × (the D-A)/d}=0.1 ~ 0.3 of rubber seal matrix 1, thickness c=C-0.1 ~ the C-1 of rubber seal matrix 1.
Further, as shown in Figure 1, the inner peripheral surface of described rubber seal matrix 1 is cylndrical surface, and the outer peripheral surface of rubber seal matrix 1 is middle part arc surface outwardly.Setting like this, for being arranged on the central axis in this rubber seal matrix 1, rubber seal matrix 1 does not rotate, but with the occasion that external moving part together moves reciprocatingly.
Further, as shown in Figure 3, the inner peripheral surface of described rubber seal matrix 1 is the arc surface that middle part is inwardly given prominence to, and the outer peripheral surface of rubber seal matrix 1 is cylndrical surface.Setting like this, does not rotate for the central shaft be arranged in this rubber seal matrix 1, only moves reciprocatingly, the occasion that rubber seal matrix 1 together moves reciprocatingly with external moving part.
Working procedure of the present utility model is: the rubber seal matrix 1 described in Fig. 1 is put into the pilot hole 2 described in Fig. 1, and rubber seal matrix 1 to-and-fro motion under the effect of intermittent oil pressure, realizes combination or the separation of automatic transmission.
Or the rubber seal matrix 1 described in Fig. 3 is put into the pilot hole 2 described in Fig. 4, and rubber seal matrix 1 to-and-fro motion under the effect of intermittent oil pressure, realizes combination or the separation of automatic transmission.
