Oil makes to form good oil sealing effect between ontology and cylinder body, so that dual oil sealing effect is formed, further by the first storage
Oil ring groove is set on body outer wall in left-hand screw shape, and the second oil storage annular groove is set to body outer wall in right-hand screw shape
On, then the coverage area of oil sealing is improved, and then ensure good oil sealing effect.
The utility model is further arranged to: outer groove on the end face of the second end of the ontology, is set on the inner wall of ontology
There is the diversion trench being connected to outer groove, diversion trench one end is connect with outer groove, is set between the other end and inner body wall of diversion trench
There is water conservancy diversion inclined-plane, the angle between water conservancy diversion inclined-plane and the slot bottom of diversion trench is between 150 degree of -160 degree.
By using above-mentioned technical proposal, outer groove on the end face of the second end of ontology, the inner wall of ontology be equipped with it is outer
The diversion trench of annular groove connection, diversion trench one end are connect with outer groove, and water conservancy diversion is equipped between the other end and inner body wall of diversion trench
Inclined-plane is arranged using the above structure, cooperates diversion trench by outer groove, lubricating oil is directed in ontology, then is ensured good
Lubricant effect, and the angle between water conservancy diversion inclined-plane and the slot bottom of diversion trench is then further mentioned between 150 degree of -160 degree
High good lubricant effect.
The utility model is further arranged to: the ratio between the groove depth and notch bore of the first oil storage annular groove exists
Between 1.8-2, the ratio between the groove depth and notch bore of the second oil storage annular groove is between 1.8-2.
By using above-mentioned technical proposal, ratio between the groove depth and notch bore of the first oil storage annular groove 1.8-2 it
Between, the ratio between the groove depth and notch bore of the second oil storage annular groove is arranged, between 1.8-2 by setting using the above structure
The first and second oil storage annular groove is set, using groove depth is increased, the mode for reducing notch bore carries out control oil pump capacity, so that ontology and cylinder
Small-scale oil enveloping structure is formed between body, and then ensures good oil sealing effect.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of caliper piston embodiment of the utility model.
Fig. 2 is a kind of schematic cross-sectional view of caliper piston embodiment of the utility model.
Specific embodiment
