Description
Technical field
The utility model relates to a kind of automotive brake, is specifically related to a kind of automotive brake sliding axle.
Background technique
Sliding axle is equipped with in automotive brake inside, sliding axle is mounted in parts on break caliper, sliding axle upper end is fixed on caliper by screw rod, usually seal ring is arranged with to prevent leakage of oil on the top of sliding axle cylindrical, but shortcoming is seal ring easily to be moved axially on sliding axle, reliably can not be located, therefore can not be kept excellent sealing; Further, the axostylus axostyle of sliding axle is polished rod, often produces air entrapment during braking operation between sliding axle and the slide opening coordinated after relative sliding, can affect braking ability after long-time.
Summary of the invention
In view of the deficiency of background technique, technical problem to be solved in the utility model is to provide one and can carries seal ring and can have reliable location and excellent sealing to seal ring, is easy to exhaust simultaneously, improves the brake slips axle of braking ability during braking operation.
For this reason, the utility model adopts following scheme to realize:
Brake slips axle, comprise axostylus axostyle and the screw rod being located at axostylus axostyle top, the bottom end face of axostylus axostyle is provided with Wrench handle hole, it is characterized in that: axostylus axostyle, screw rod and Wrench handle hole one cold-heading molding, the top of described axostylus axostyle cylindrical is provided with seal ring positioning step, seal ring positioning step is provided with upper and lower turned welt on cylindrical, upper turned welt has local major diameter cylindrical A, lower turned welt has local major diameter cylindrical B, seal ring positioning step has local major diameter cylindrical C, and cylindrical A, cylindrical B are identical with the diameter dimension of cylindrical C.
As preferably, the axostylus axostyle cylindrical being positioned at below seal ring positioning step offers vertical groove.
After adopting technique scheme, first axostylus axostyle is provided with the location of seal ring positioning step for seal ring, and because the turned welt up and down of seal ring positioning step designs, seal ring is reliably located on seal ring positioning step, simultaneously because seal ring positioning step, in the setting of upper, middle and lower three sections of major diameter cylindricals of cylindrical, can ensure the excellent sealing between seal ring endoporus and seal ring positioning step.In addition, arranging when solving braking operation of vertical groove can produce the problem of air entrapment between sliding axle and the slide opening coordinated after relative sliding, improves braking ability.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is shape assumption diagram of the present utility model.
Embodiment
As shown in the figure, brake slips axle of the present utility model, comprise axostylus axostyle 1 and the screw rod 7 being located at axostylus axostyle 1 top, the bottom end face of axostylus axostyle 1 is provided with Wrench handle hole 2, axostylus axostyle 1, screw rod 7 and Wrench handle hole 3 one cold-heading molding, the top of described axostylus axostyle 1 cylindrical is provided with seal ring positioning step 5, seal ring positioning step 5 is provided with turned welt 6 and lower turned welt 4 on cylindrical, upper turned welt 6 has local major diameter cylindrical A, lower turned welt has local major diameter cylindrical B, seal ring positioning step 5 has local major diameter cylindrical C, cylindrical A, cylindrical B is identical with the diameter dimension of cylindrical C, axostylus axostyle 1 cylindrical being positioned at seal ring positioning step less than 5 offers vertical groove 3.
