And this case utility model is mainly to see through brake cable connection for transmission assembly pining down a kind of line traffic control oil pressure type bicycle brake structure of brake units for above-mentioned with brake handgrip place, and the following announcement of its relevant case.
See also the TaiWan, China patent No. 476324, it discloses a kind of Bicycle dished brake master cylinder arrangement, refers to especially a kind of simple installation and the good person of antiseep effect; Establish internal thread segment in permanent seat leading portion periphery, relatively establish internal thread segment in pipe section, forming a space in permanent seat places for spring, this front end place, space establishes a guide groove and fills for an O shape ring, this brake cable joint leading portion extends a stock section, it stretches into pipe section and connects with the oil hydraulic cylinder body, its end forms a head, head vertically provides a fixed orifice, provide a check screw spiral shell to fasten and decide brake cable, head is positioned at the inboard ring of locating of fixed orifice and establishes a depressed part, fixes for dust protecting cap end openings ring bundle.
Yet, because brake cable directly is connected with piston, when the user wants to carry out the brake cable adjustment, as the tension brake cable, also can drive simultaneously the movement of piston, the fluid manhole appendix is blocked and cause to form bounded system in oil hydraulic cylinder, and then cause gas lock abnormal.
The utility model content
Therefore, the purpose of this utility model be to address the above problem and provide a kind of and reduce production costs, easy disassembly, and need not oil pipe, and then can avoid the transmission of oil pipe and cause the line traffic control hydraulic type brake structure of bicycle of the loss of power.
For reaching above-mentioned purpose, the utility model provides a kind of line traffic control hydraulic type brake structure of bicycle,
One clamp parts; And
One drive disk assembly, one end and this clamp members are also controlled the start of these clamp parts, this drive disk assembly has an oil groove, a piston, a transmission arm and a push rod, this piston is arranged in this oil groove movably, this transmission arm is arranged on outside these clamp parts, and this transmission arm one end is connected with the outer end away from these clamp parts of this oil groove pivotly, one end of this piston sees through this push rod and is connected with an appropriate location between the two ends of this transmission arm, this transmission arm away from an end and a brake cable interlock of this oil groove pivot joint.
Wherein, this oil groove more arranges a brake cable tuning knob outward, this brake cable from this transmission arm away from being connected with a brake handgrip of a bicycle via this brake cable tuning knob with an end of this oil groove pivot joint, be connected with a fixing button between this transmission arm and this push rod, this fixing button can be controlled the release of this transmission arm or fix length and the elasticity of this brake tuning knob in order to adjust this brake cable.
Wherein, these clamp parts and this drive disk assembly are formed in one.
Wherein, two brake shoes that these clamp parts are connected with relatively and the interval arranges, an end of this drive disk assembly and clamp members are also controlled the mutual start of this two brake shoes of these clamp parts.
The beneficial effects of the utility model: by said structure, the utility model is by the clamp parts and the drive disk assembly that link together, connect with the original brake cable of Regular Bicycle, and need not brake handgrip connected pipes by bicycle with driven plunger, reducing the loss of oil pipe power that transmission is caused, the while can easy disassembly and reduces production costs.

The primary clustering nomenclature
The line traffic control hydraulic type brake structure of 1 bicycle; 2 clamp parts; 21 brake shoes; 3 drive disk assemblies; 31 oil grooves; 311 brake cable tuning knobs; 312 apertures; 313 macropores; 32 pistons; 321 oil sealings; 33 transmission arms; 331 fixing buttons; 34 push rods; 4 brake cable.
The specific embodiment
Please refer to Fig. 1 to Fig. 5, the line traffic control hydraulic type brake structure 1 of bicycle of the present utility model comprises clamp parts 2 and a drive disk assembly 3; Wherein, clamp parts 2 and drive disk assembly 3 can be formed in one, but not as limit.
Two brake shoes 21 that clamp parts 2 are connected with relatively and the interval arranges.
One end of drive disk assembly 3 is communicated with and controls the mutual start of two brake shoes 21 with clamp parts 2, its detailed start will be in rear detailed description.
Moreover, drive disk assembly 3 has an oil groove 31, a piston 32, a transmission arm 33 and a push rod 34, be full of fluid in oil groove 31, piston 32 is arranged in oil groove 31 movably, transmission arm 33 is arranged on clamp parts 2 outsides, and an end of transmission arm 33 is connected with the outer end away from clamp parts 2 of oil groove 31 pivotly, one end of piston 32 sees through push rod 34 and is connected with an appropriate location between the two ends of transmission arm 33, this appropriate location can be ends contiguous near transmission arm 33 and oil groove 31 pivot joints, but not as limit; And transmission arm 33 away from an end and brake cable 4 interlocks of oil groove 31 pivot joints.
in addition, the outer brake cable tuning knob 311 that more arranges of oil groove 31, brake cable 4 end away from oil groove 31 from the transmission arm 33 is connected with a brake handgrip (not shown) of a bicycle (not shown) via brake cable tuning knob 311, be connected with a fixing button 331 between transmission arm 33 and push rod 34, fixing button 331 can be controlled the release of transmission arm 33 or fix, and length and the elasticity of brake cable tuning knob 311 in order to adjust brake cable 4, and the contiguous brake lines button of oil groove 31 311 places are provided with an aperture 312, oil groove 31 is provided with a macropore 313 away from brake cable tuning knob 311 places, that is, general status at ordinary times, fixing button 331 is release position, makes transmission arm 33 and brake cable 4 interlocks, and then drives the movement of piston 32, in addition, when wanting to carry out brake cable 4 adjustment, can be stationary state by depressing fixing button 331, with fixed conveyor arm 33, then by brake cable tuning knob 311 so that brake cable 4 is carried out the adjustment of length and elasticity, not only structure is simplified, and easy to operate, more can not cause the oil sealing 321 on an end of the contiguous brake cable tuning knobs 311 of piston 32 to block to live aperture 312, and cause the interior formation bounded system of oil groove 31, and then cause gas lock abnormal.
Therefore, when the rider depresses brake handgrip (not shown) and when straining brake cable 4 (this moment for mechanical type start), drive simultaneously transmission arm 33 towards oil groove 31 direction pivotables, and then drive push rod 34 pushing pistons 32 and move towards the direction of clamp parts 2, last two brake shoes 21 (this moment is as the hydraulic type start) close to each other of controlling again clamp parts 2 in the oil pressure mode are to reach the effect of brake.
By said structure, the utility model is by the clamp parts 2 that link together and drive disk assembly 3, connect with the original brake cable 4 of Regular Bicycle, and need not brake handgrip connected pipes by bicycle with driven plunger (please refer to front case part), reducing the loss of oil pipe power that transmission is caused, the while can easy disassembly and reduces production costs.
The announcement of the above embodiment only in order to the utility model to be described, is not to limit the utility model, therefore the displacement of the change of numerical value or equivalent elements must be subordinate to category of the present utility model such as.
