Fig. 2 is the rear view of the oil leakage-proof brake calipers of Fig. 1.
Fig. 3 is the sectional view of A-A along the line of the oil leakage-proof brake calipers of Fig. 1.
Embodiment
For the technical solution of the utility model can more clearly be showed, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, be oil leakage-proof brake calipers of the present utility model, comprise that the secondary sliding axle 20, of a main sliding axle 10, is set in mounting bracket 30 on this main sliding axle 10 and secondary sliding axle 20, is arranged on the caliper 40 on this mounting bracket 30.The in-built piston 41 of this caliper 40, be fixed on one end of piston 41 right braking plate 42, be arranged on the lower patch 44 between left braking plate 43 relative with right braking plate 42 in caliper 40 and setting and this right braking plate 42 and left braking plate 43.This caliper 40 also comprises a guide rod 45, and this guide rod 45 wears described right braking plate 42 and left braking plate 43, and right braking plate 42 can be slided along guide rod 45.
One end of described main sliding axle 10 is fixing with described mounting bracket 30 by self-locking nut 16, and the other end cunning of main sliding axle 10 is established and inserted a stationary platen (figure is mark not).Between this main sliding axle 10 and mounting bracket 30, be provided with a rubber case 11, this rubber case 11 is closely set on this main sliding axle 10, and form an oil pocket with the outer wall of this main sliding axle 10, by inject lubricant oil in oil pocket, guarantee the long-term use of brake calipers, improve wear resistance, guarantee the sealing of lubricant oil simultaneously.
One end of described secondary sliding axle 20 wears and is fixed on described mounting bracket 30, and the other end is slidably connected with described caliper 40 by a secondary sliding axle rubber sleeve 21.This pair sliding axle rubber sleeve 21 is arranged between the outer wall of secondary sliding axle 20 and the inwall of caliper 40, to guarantee the lubricity of the relatively secondary sliding axle 20 of caliper 40.Between this pair sliding axle 20 and mounting bracket 30, be provided with a spring washer 22.
The inwall of the corresponding piston 41 of described caliper 40 is provided with a piston dust ring 46 and a rectangular seal 47, has both prevented that the dust of outside from entering piston 41 bottoms pollution force feeds, avoids the outside seepage of force feed simultaneously.One end of described guide rod 45 is fixed on caliper 40 by nut, nut and caliper 40 axially between by a screw plug 50, carry out oil seal.Understandably, other one end of described guide rod 45 can arrange equally a screw plug and seals.
