Description
Technical field
This utility model belongs to caliper accessory technical field, especially relates to a kind of studdle.
Background technology
Caliper is the significant components realizing motor vehicles parking braking, caliper mainly include housing,
Studdle, adjustment bolt and the drive mechanism of composition, the piston being loaded in housing, braking brake block
Deng.Studdle is used to drive adjustment bolt and the drive mechanism of composition thereof, drives piston movement with this,
Make piston axial straight line sliding, then promote braking brake block clamping brake disc by piston, thus realize staying
The purpose of car braking.Existing studdle owing to adjusting the drive mechanism of bolt and composition thereof in driving
During, easily it is worn, causes service life short, and studdle is being braked the entirety of pincers
During assembling, efficiency of assembling is low.Therefore, it is necessary to improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, it is provided that a kind of studdle,
It has efficiency easy to assembly height and the feature of length in service life.
To achieve these goals, this utility model be the technical scheme is that a kind of studdle,
Including main rod body, connecting rod and a fastener, the upper body of rod of described connecting rod is provided with screw thread, and the lower body of rod sets
Being equipped with anti-slop serrations, the lower end of described connecting rod is connected with the upper end of main rod body, and the lower end of described main rod body is even
Connect a fastener；The upper end of described main rod body is provided with the cannelure along main rod body periphery；Described fastener
Lower surface is provided with several and rolls seat, and described rolling seat includes the groove of arc surface shape, described groove
Both sides are respectively arranged with the gradually deep trouth along groove direction.
Described rolling seat has three, and three rolling seats in the lower surface of a fastener with the central shaft of a fastener are
Center is uniformly distributed.
The surface-coated of described groove and gradually deep trouth has wear-resistant coating, described wear-resistant coating to be chrome coating or titanium
Coating.
Use after said structure, this utility model the most advantageously: this practicality
The novel lower surface at fastener is provided with the rolling seat that ball can be allowed to carry out predetermined rolling, can reduce its
Abrasion during use, increases service life, and the setting rolling seat also helps the overall assembling of caliper,
Improve efficiency of assembling；Cannelure is used for mounting and adjusting bolt dust cover, is conducive to increasing the use longevity of product
Life.
