Oil pressure brake caliper arrangement

Technical field

The utility model relates to a kind of oil pressure brake caliper arrangement, is meant that especially the clamp body construction is simplified, steadiness promotes and drive the brake clamp that have more safety.

Background technology

Bicycle is because of having the convenience and the manoevreability of height; Become indispensable necessity in China common people daily life; No matter be the walking-replacing tool that is used for amusement and recreation or is used as daily life, all can see its figure everywhere, also because the large contingent that uses and having wide range of applications; Therefore bicycle safe property receives people especially and payes attention to; Also becoming influences the choice important document that people choose bicycle, and the brake of the relative V of brake clamp folder have do not receive that weather influences, the brake facing life-span is long, the required power of brake is less and more can the loss wheel rim etc. characteristics, therefore favored by the customer.

Therefore also there are many creators to propose the related application case to the brake caliper arrangement; And in the tw Taiwan " disk brake caliper " patent case of patent case number I230228 number; It comprises: a body; Have around an axis and define the inside face of a perforation, two are formed on the groove of this inside face; Two pistons can be contained in the perforation of this body with relatively moving, and have an outside face respectively; Two oil sealings, ring is solid at this outer surface of piston respectively, and is contained in this body groove; Two portions of giving up the throne; Have one respectively around this axis and be formed on the inclined-plane in the body groove; This inclined-plane has that contiguous this axis and adjacent this piston advance to move an end of direction and away from the other end of this axis and adjacent this piston involution direction; Make this oil sealing when this piston advances to move, be hampered by this inclined-plane, produce distortion and accumulation energy of deformation and when discharging energy of deformation, drive this piston resilience.

But this kind brake caliper arrangement is utilized the combination of two clamp cylinder bodies, and piston is packed into towards inner by cylinder body is outside, though easy to assembly; But when actual the utilization,, cause internal works by grunge pollution because structure built on the sand, and is very easy to ooze out brake solution; And cause brake failure, and then influence traffic safety, moreover; This kind also causes the loose of structure easily by the structure of two cylinder bodies combination, and period of service one is of a specified duration, and braking effect is also along with fading away; Add aforesaid oil impregnate problem, make traffic safety precarious.

In response to the shortcoming of above-mentioned patent, there is the creator to be directed against above-mentioned disk brake caliper patent and proposes to improve, please with reference to " brake clamp structural improvement " patent case of tw Taiwan patent case number M385172 number; It comprises a cylinder body, and wherein: this cylinder body is integrally formed, and this cylinder interior is provided with predetermined accommodation space; This accommodation space content is provided with a claw, and this claw two ends group is provided with two Linings, and this two Linings outside engages two piston assemblies respectively; This two piston assembly is installed towards the outside by the inboard, whereby, and through integrally formed cylinder body; And, make this body have preferable structural strength and preferable braking effect by the piston assembly of inboard towards outside installing.

Yet this kind design; Also be to offer two openings at the clamp two ends, the brake accessory of will being correlated with is again inserted in two openings of clamp body in regular turn, and this kind design also makes utilization go up the clamp structure relatively built on the sand; And further have influence on the effect that oil pressure brake is used; And it also exists complex structure, the problem that cause processing, assembly cost increases, and make the integral product competitive power reduce.

In view of this; This creator improves to the existing problem points of above-mentioned existing brake clamp; Hope is by the manufacturing development of being engaged in Related product for many years and design experiences; Shortcoming to above-mentioned is improved, and after design and the scrupulous assessment, just designs the utility model that improves the product whole competitiveness in detail.
