Description

Fare conducts the hydraulic type brake gear voluntarily

The utility model relates to a kind of bicycle brake device, the particularly a kind of conduction of fare voluntarily hydraulic type brake gear.

The brake system of bicycle can generally be divided into two kinds at present, a kind of is the brake structure that general line passes system, it is the brake cable body that interlock outer tool plastic casing in brake crank place coats the core pipe, be located at the brake of wheel both sides with start, so that this brake is able to wheel is braked, so structure has following shortcoming in fact, such as:

1, brake is uncertain: when its two groups of brakes are collided or impact, produce crooked phenomenon, action is difficult to be braked in the both sides of wheel simultaneously in the time of can't be certain, causes the uncertain disappearance of brake.

2, brake has the sense of discomfort: promptly its brake is to the drag friction strength of wheel, system is fully to pull moving strength action, there is no the structure of any foot therebetween for slow weighing apparatus, very easily produce the sense of pause and transition in rhythm or melody, not only make rider's discomfort, more be subjected to precipitate vibration, the smoothness and the safety of influence driving.Six No. two " bicycle hydraulic type brake " novel patents of Taiwan the 8420 pseudo-ginseng, its permanent seat place that lies in brake handgrip articulated section is provided with a hydraulic pressure chamber, hydraulic pressure chamber is provided with piston and can be brake handgrip institute interlock, and hydraulic pressure chamber is delivered to two groups of brakes by the road, piston in brake, push rod and brake lining again, make the form start that integral body can hydraulic pressure, though so structure can reduce the pause and transition in rhythm or melody sense that system caused of line biography, increase the stationarity and the accuracy of whole brake, but still have following shortcoming:

1, brake reaction can produce error: be its suitable elasticity nargin all to be arranged because of each pipeline, when force feed hydraulic oil, the elastic error that its each several part is accumulated is a multiple that multiplies each other, cause the force feed of hydraulic oil integral body uncertain, even the speed of pressing of the opening time of brake and brake crank has certain error, make the speed of response of brake cause unnecessary delay, jeopardize rider's life security, and because the length of this pipeline is long, not only be easy to collude his article of khaki and cause this line rupture protection valve, easier rising-heat contracting-cold environmental effect because of pipeline, the error that this pipeline is caused is bigger.

2, involve great expense: the design of Hydraulic System of integral body, the extending length of pipeline length very especially, spent ten minutes surprising is so there is necessity of improvement.

This creator in view of this, for making of the respective outer side edges hydraulic structure design of whole brake structure by the line biography, the transmission drive hydraulic structure of at high speed, and effectively shorten the brake reaction time,, be to develop a kind of a kind of bicycle line conduction hydraulic type brake gear that meets above-mentioned condition more with the brake high stability and brake certainty of hydraulic structure.

The purpose of this utility model is to provide a kind of conduction of fare voluntarily hydraulic type brake gear, it is with brake crank interlock brake cable, cooperate and to hold the hydraulic control pump of interlock to drive brake in addition,, more meet economic principle to reach whole high efficiency, high-comfort braking quality with hydraulic way.
