For a larger brake caliper body, the required internal pressure is also larger, the pressure born by an external blocking part is also larger, the requirement on the part is higher, the requirement on the machining precision of the matching part of the caliper body is also high, the corresponding cost is high, and the probability of potential safety hazard is high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an anti high pressure floating clamp has solved the problem that the braking inlay can't bear great pressure among the prior art.

The technical scheme of the utility model is realized like this:

the high pressure resisting floating caliper includes a caliper body, friction plates and a brake disc, a piston hole inside the caliper body, an air releasing screw hole outside the piston hole and communicated with the outer surface of the caliper body, a casting connecting hole inside the caliper body and communicated with the piston hole and the air releasing screw hole, an air releasing screw inside the air releasing screw hole and a movable piston inside the piston hole, and the piston moves downwards to push the friction plates to contact the brake disc for braking.

Further, a first end of the cast connecting hole is communicated with the piston hole, a second end of the cast connecting hole is communicated with the deflation thread hole, and the diameter of the cast connecting hole is gradually reduced from the first end to the second end.

Further, the air release threaded hole is communicated with the second end of the casting connecting hole through the connecting hole, and the diameter of the connecting hole is smaller than that of the air release threaded hole.

Therefore, no matter which structure has the air bleeding screw assembled in the air bleeding screw hole, the piston is assembled in the piston hole, and the difference is that the air bleeding screw hole is communicated with the piston hole in which mode. The internal pressure and the leakage risk are kept, so that the clamp body reduces an external useless machining structure, the machining difficulty is reduced, and the cost is saved. And secondly, the casting connecting holes arranged inside replace external processing, so that the overall compressive strength of the clamp body can be improved, the safety risk of leakage is reduced, and the attractiveness of the surface of a casting is kept.

Detailed Description

The present invention will be described in further detail with reference to examples and drawings.

As shown in figure 1, the high-pressure-resistant floating caliper comprises a caliper body, a friction plate and a brake disc, wherein a piston hole 1 is formed in the caliper body, an air release threaded hole 4 is formed in the outer portion of the piston hole 1, the air release threaded hole 4 is communicated with the outer surface of the caliper body, a casting connecting hole 2 communicating the piston hole 1 with the air release threaded hole 4 is further formed in the caliper body, an air release screw 5 which can be screwed out is assembled in the air release threaded hole 4, a movable piston is assembled in the piston hole 1, and the piston moves downwards to push the friction plate to contact with the brake disc to achieve braking.

The beneficial effects of the utility model are summarized as: one of them, replaced by casting connecting hole 2 structure by inside gassing screw hole 4 of 3 intercommunications of surface machining connecting hole and piston hole 1 to block up the surface hole with the accessory, the utility model discloses an inside casting connecting hole 2 has replaced and has blockked up the surface hole by accessory from the outside, and original structure is by a hole of outside processing, gets through inner structure, but the hole has been retained on the surface, leads to inside unable sealed, then original structure is plugged up the hole from the outside with an accessory, in order to reach sealed effect, has cancelled outside processing and accessory jam scheme, uses inside casting connecting hole 2 to reach the linkage effect. The internal pressure and the leakage risk are kept, so that the clamp body reduces an external useless machining structure, the machining difficulty is reduced, and the cost is saved. Secondly, replace outside processing by the casting connecting hole 2 that sets up inside, can promote the whole compressive strength of pincers body, reduce the safe risk of leaking, keep the aesthetic property on foundry goods surface.

Referring to fig. 1, in one embodiment, a first end of a cast connection bore 2 communicates with a piston bore 1, a second end of the cast connection bore 2 communicates with a bleeder screw bore 4, and the cast connection bore 2 tapers in diameter from the first end to the second end. Thus, the cast connection hole 2 has better sealing effect and can bear larger pressure when exhausting.

Referring to fig. 1, in one embodiment, the bleeder screw hole 4 communicates with a second end of the cast connection hole 2 through a connection hole 3, the connection hole 3 having a smaller diameter than the bleeder screw hole 4. After the air release screw 5 is screwed, the conical tip can seal the orifice of the connecting hole 3, and the sealing function is achieved. A connecting threaded hole with smaller diameter is arranged below the deflation threaded hole 4, so that the sealing effect of the deflation screw 5 is better.

The utility model discloses a theory of operation: the piston hole 11 and the air release threaded hole 44 are combined by the casting connecting hole 22 and the connecting hole 3 to form a communicated exhaust connecting structure, a piston is arranged in the piston hole 11, and after an internal pressure difference value and an external pressure difference value become small due to air generated in the process of using under the action of hydraulic pressure accessed from an oil inlet hole, the piston cannot return after being braked and pushed out, so that a braking system is always kept in a tightly-holding state. And the deflation screw 5 matched with the deflation threaded hole 44 is unscrewed, so that the air in the piston is finally exhausted from the deflation threaded hole 4 through the connecting hole 3 through the casting connecting hole 22, the difference value of the internal pressure and the external pressure of the piston hole 11 is kept, and the normal use of the brake system is kept.
