In above-mentioned hydraulic braking pincers, described groove is the sphere invaginated type.The groove of sphere invaginated type can conduct the Driving force of hydraulic oil preferably.
In above-mentioned hydraulic braking pincers, be fixed with the guide structure that makes things convenient for the caliper location and installation on the described caliper.
In above-mentioned hydraulic braking pincers, described guide structure is a guide finger, and an end and the caliper of guide finger are connected, and the other end of guide finger stretches out caliper and is positioned at the jaw place.Caliper passes connected piece by guide finger and makes the caliper Primary Location when mounted, by bolt caliper and connected piece is connected caliper easy for installation afterwards again.
As another kind of situation, in above-mentioned hydraulic braking pincers, described guide structure comprises guide blot, guideway and guiding sheath, described guiding sheath passes caliper and fixes with caliper, guiding sheath internal fixation has guideway, and described guide blot is threaded with guideway and an end of guide blot is positioned at the jaw place.Guiding sheath one end has and turns edge and the caliper clamping the other end and caliper riveted joint, the connection precision of guiding sheath assurance guideway.Caliper passes connected piece by guide blot and makes the caliper Primary Location when mounted, by bolt caliper and connected piece is connected caliper easy for installation afterwards again.
In above-mentioned hydraulic braking pincers, be provided with seal ring between described piston and the caliper.Seal ring has guaranteed the sealing of piston and caliper.
In above-mentioned hydraulic braking pincers, be fixed with dust-proof cover between the outer end of described piston and the caliper port.Dust-proof cover makes impurity such as dust can't enter between piston and the caliper.
Compared with prior art, the hydraulic braking pincers that provide of the utility model have the following advantages:
1, piston is positioned at the sunken end face formation groove of piston cavity in this hydraulic braking pincers, groove that the conductivity that has guaranteed the hydraulic oil Driving force is set is good, and make even piston stress, piston can be regulated the gap of self and piston cavity automatically in movement process.
2, this hydraulic braking pincers are provided with guide structure, have made things convenient for the location and installation of caliper like this.
