Description
The utility model belongs to bicycle assembly parts, particularly a kind of jig arm formula oil brake.
In the present self-propelled vehicle and bicycle brake device, it is to adopt mechanical type lead-in wire drive mechanism that sizable ratio is arranged, and only has small part system to adopt the hydraulic type brake structure.
Degradation of energy was less when hydraulic type brake gear major advantage was its strength transmission, comparatively laborsaving in the operation, and it is swift in motion, really, can control brake exactly, and be not easy to lose and do not have the effect of going as traditional easy invar rope fracture of lead-in wire control brake, therefore, self-propelled vehicle and bicycle adopt the ratio of hydraulic type brake more and more higher now.
Yet because the cost of hydraulic type brake is high than the cost of conventional wire control formula brake, therefore, most now oil pressure brake all is applied on the self-propelled vehicle, and bicycle uses the ratio of oil pressure brake also considerably small.
The employed hydraulic type brake apparatus of bicycle is mainly distinguished two kinds now; A kind of is disc brake device; Another kind of then for utilizing two oil hydraulic cylinders that are arranged on the cycle wheel both sides to promote two oil hydraulic cylinder formulas of brake facing.Yet the jig arm formula brake gear that its cost of hydraulic type brake gear of above-mentioned two kinds of forms drives far above general cable wire, therefore, the example that the oil pressure brake is used on the bicycle is also quite rare.
Cause the reason of the bicycle oil pressure brake cost costliness of commonly using to mainly contain following points:
1, the disc type oil brake is owing to must install a brake disc on the wheel shaft of bicycle, and device oil pressure brake, therefore, must be with the whole change of front wheel spindle structure of bicycle, and must on the front fork tube of bicycle or vehicle frame, increase the pedestal of device oil pressure brake, therefore, use its infrastructure cost to greatly increase.Though and two oil hydraulic cylinder formula brake gear does not need to change wheel shaft structure, but, therefore, make its cost also become quite expensive because its fixed sturcture that oil hydraulic cylinder is installed is also quite complicated.
2, the recovery spring of general hydraulic type brake gear all is the cylinder interior of device at oil hydraulic cylinder, thus, will make the structure of cylinder interior of oil hydraulic cylinder become complicated, and recover spring can with the mutual friction mutually of cylinder body interior sidewall surface, in addition, bicycle brake device is very strict for the requirement of volume usually, therefore device recovers spring in limited space, will make the design of cylinder body become difficult, and can make other parts of cylinder interior, structure as piston, packing ring etc. also must be dwindled, and easy et out of order.Therefore, will make that cylinder body is complicated and be difficult to processing, therefore, make its cost become expensive.
The purpose of this utility model provide a kind of simple in structure, handling ease, cost low, install and be easy to jig arm formula oil brake.
The utility model comprise terminal installing brake facing two jig arm, press oily structure, be hubbed at two jig arm upper end and with the oil pressure actuated structure of pressing oily structure to be communicated with and be connected with recovery spring on two jig arm; Two jig arm are hubbed at wheel frame both sides with its middle part, and its terminal brake facing contacts with the wheel frame; The oil pressure actuated structure comprises that cylinder body and slip place in the cylinder body and make the piston that linear reciprocation is slided in it; Press oily structure to comprise that cylinder body and slip place in the cylinder body and driven by brake crank and in it, make the piston that linear reciprocation is slided and hydraulic oil produced oil pressure.
