Abstract
The utility model relates to a hydraulic transmission system for the braking of bicycles, which is mainly composed of a braking handle 5, an active piston 2, an active oil cylinder 1, an oil pipeline 9, an executing piston 12 and an executing oil cylinder 10. Because of little transmission resistance, the utility model has the advantages of flexible and light braking, quick return, reliable use, convenient adjustment, no maintenance, wide application range, etc. The utility model is especially suitable for bicycles, such as racing bicycles, mountain bicycles, etc., the requirements for braking performance of which are high.
Description
The utility model relates to a kind of bicycle brake power hydraulic system.
At present bicycle brake has a dual mode with what transmission system generally adopted: a kind of is that many places lever reinforcing bar connects driving system; Another kind is a wire flexible axle driving system.Before a kind of driving system exist not only that the transmission resistance is big, efficient is low, and messenger chain needs often to adjust, and snaps easily during emergency braking, causes serious consequence, because its parts are more, makes and install also cumbersome in addition.Though wire flexible axle driving system is than preceding a kind of certain advantage that has, it is big also to exist the transmission resistance, and efficient is low, needs often maintenance, also easily snap during emergency braking, and its wire and the amateur equipment of flexible axle axle skin can't be produced.
The utility model is both for overcoming the shortcoming design-calculated of above-mentioned driving system.
Fig. 1 a kind of embodiment scheme drawing of the present utility model.
Among Fig. 1: 1-actuating cylinder 2-active piston 3-support
4-bearing pin 5-brake-applying handle 6-adjustment nut
7-adjustment nut 8-handlebar 9-transport pipe
10-carries out oil cylinder 11-and carries out piston 12-adjustment nut
The pincerlike lock of 13-left side sheet 14-left side braking rubber 15-bicycle rim
The right sheet 18-of the pincerlike lock of the right braking of 16-rubber 17-bearing pin
19-pin 20-pull back spring 21-pin
Below in conjunction with Fig. 1 the utility model is further described.
Support 3 is fixed on the handlebar, and actuating cylinder 1 is fixed on the support 3, and brake-applying handle 5 is connected with support 3 by bearing pin 4; Active piston 2 can slide in the endoporus of actuating cylinder 1; Adjustment nut 6 and adjustment nut 7 can rotate the position of adjusting brake-applying handle 5 in the bar portion of active piston 2; The two ends of transport pipe 9 are connected with execution oil cylinder 10 with actuating cylinder 1 respectively; The right sheet 17 of pincerlike lock is fastenedly connected with execution oil cylinder 10; Pincerlike lock left side sheet 13 is connected by the right sheet 17 of bearing pin 18 and pincerlike lock.Pin 19 and pin 21 are affixed with pincerlike lock left side sheet 13 and the right sheet 17 of pincerlike lock respectively; The two ends of pull back spring 20 are connected with pin 21 with pin 19 respectively.Left side braking rubber 14 and right braking rubber 16 are affixed with pincerlike lock left side sheet 13 and the right sheet 17 of pincerlike lock respectively; Adjustment nut 12 can rotate in the bar portion that carries out piston 11, in order to adjust the aperture of pincerlike lock; Carrying out piston 11 can slide in the endoporus of carrying out oil cylinder 10.Be full of hydraulic oil in actuating cylinder 1 and execution oil cylinder 10 and the transport pipe 9.
When pressing brake-applying handle 5 with hand, brake-applying handle 5 promotes active piston 2 by adjustment nut 7, and hydraulic oil is released, and hydraulic oil flows into through transport pipe 9 and carries out oil cylinder 10, promotes to carry out piston 11, carries out piston 11 and promotes pincerlike lock left side sheet 13 by adjustment nut 12.Because pincerlike lock left side sheet 13 inwardly closes up with the right sheet 17 of pincerlike lock, force left side braking rubber 14 and right braking rubber 16 to press to bicycle rim 15, reach the purpose of braking.This moment, pull back spring 20 was stretched.When end of braking, discharge brake-applying handle 5, pull back spring 20 retracts pincerlike lock left side sheet 13 and the right sheet 17 of pincerlike lock, thereby it is moving to travelling backwards to promote to carry out piston 11, hydraulic oil flows back to actuating cylinder 1 through transport pipe 9, promote active piston 2, and active piston 2 promotes brake-applying handle 5 returns by adjustment nut 7.
Distinguishing feature of the present utility model:
1. brake flexibly, light, return is rapid.Owing to be hydrostatic drive, the transmission resistance is very little, thus brake laborsaving, response rapidly, light and flexible.When release lever 5, system can reset rapidly, finishes braking.
2. easy to adjust.When long-time use, when hydraulic oil has small leakage, can adjust the control position of active piston 2 and brake-applying handle 5 easily by rotation adjustment nut 6 and adjustment nut 7, to guarantee effective braking; In addition, also can adjust the aperture of pincerlike lock easily by swivel nut 12.
3. wide accommodation.If actuating unit is not pincerlike lock, but during the brake equipment of other type, connection mode is changed slightly, just can adapt to.And this system can be assemblied on any bicycle.
4. use reliable.Owing to be hydrostatic drive, mechanical transmissioning piece greatly reduces, thereby uses reliably, and fault rate reduces.
5. avoid maintenance.The present driving system of using, or need often to adjust the messenger chain tightness, or need be oily at some position, and the system that the utility model relates to can remove above-mentioned maintenance measures from.
