Description
The utility model relates to the bicycle of a kind of bicycle, particularly a kind of hydraulic braking.
The present bicycle of selling, with regard to braking, can be divided into two kinds: a kind of is lever brake type bicycle, another kind is a wire flexible axle brake type bicycle.No matter being that a kind of bicycle, all is by the handle on the handlebar power to be passed to brake rubber block by attaching parts or the steel wire that links to each other with brake rubber block, and the front and rear wheel of bicycle is carried out drag.These two kinds of structures all exist discontinuity, and steel wire snaps easily, gets rusty and is out of shape, and brake response is blunt, braking poor reliability, and transfer the brake difficulty, can not be durable in use etc. defective.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of improved hydraulic braking bicycle is provided, and it not only brakes light, sensitive, reliable, and simple in structure, durable in use, and is easy than capacity transfer.
The purpose of this utility model is achieved in that this hydraulic braking bicycle, comprise handlebar, vehicle frame, be fixed on the support on the handlebar, front fork, front-wheel, trailing wheel, saddle, drive system and brake system, and brake system is by brake handle, main pump, attached pump, the hydraulic pipe that connects main pump and attached pump is formed, main pump is fixed on the support, attached pump is fixed in front fork, on vehicle frame back vent or the bicycle brake hub, brake handle is connected with support by bearing pin, the one end is connected on the push rod of main pump, the main pump oil cylinder is separated into sap cavity and air cavity two parts by the leather cup that is fixed in the cylinder body, be provided with top cover in the air cavity, the cylinder body of sap cavity is provided with blow off valve, attached pump oil cylinder is separated into sap cavity and air cavity two parts by the leather cup that is fixed in the cylinder body, be provided with top cover in the air cavity, the cylinder body of sap cavity is provided with blow off valve, the other end that connects the attached pump push rod of attached pump top cover is connected with brake facing, and hydraulic pipe one end is connected with the sap cavity of main pump, and the other end is connected with the sap cavity of attached pump.Leather cup in main pump, the attached pump is fixed in by hollow bolt in the cylinder body of main pump, attached pump, and the push rod of main pump, attached pump passes the fixedly hollow bolt of leather cup.Be full of hydraulic fluid in main pump sap cavity, attached pump sap cavity and the hydraulic pipe.
The utility model since the power on the brake handle by hydraulic pressure transfer to brake facing, brake facing produces braking to wheel, therefore the hydraulic pipe as brake cable can not produce the problem of getting rusty, rupturing; Because the hydraulic pressure power transmission, resistance loss is less in addition, thereby brakes laborsavingly, and brake is reliable rapidly, and light and flexible avoids maintenance, long service life.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation according to the hydraulic braking bicycle that the utility model proposes.
Fig. 2 is that the utility model main pump is installed in the structural representation on the handlebar.
Fig. 3 is the cutaway view of the utility model main pump.
Fig. 4 is the cutaway view of the attached pump of the utility model.
Describe concrete structure and service condition in detail below in conjunction with accompanying drawing 1-Fig. 4 according to a kind of hydraulic braking bicycle that the utility model proposes.
This hydraulic braking bicycle, comprise handlebar (5), vehicle frame (9), be fixed on the support (7) on the handlebar, front fork (2), front-wheel (1), trailing wheel (13), saddle (10), drive system and brake system, brake system comprises identical front wheel brake system and back wheel brake system, by brake handle (6), main pump (8), attached pump (3), the hydraulic pipe (4) that connects main pump (8) and attached pump (3) is formed, the braking of left side brake handle control trailing wheel, right brake handle control front wheel brake, main pump (8) is fixed on the support (7), front wheel brake and trailing wheel braking have two attached pumps to constitute respectively, attached pump (3) is fixed on the both sides of front fork (2) or vehicle frame back vent (12), brake handle (6) is connected with support (7) by bearing pin (15), the one end is connected on the push rod (14) of main pump (8), and adjust its position by adjustment nut (16) and (17), on the push rod (14) of main pump, be provided with pull back spring (19) between brake handle (6) and the main pump (8), main pump oil cylinder (23) is separated into sap cavity (25) and air cavity (20) two parts by the leather cup (22) that is fixed in the cylinder body, be provided with top cover (21) in the air cavity (20), the cylinder body of sap cavity (25) is provided with blow off valve (24), attached pump oil cylinder (29) is separated into sap cavity (28) and air cavity (31) two parts by the leather cup (27) that is fixed in the cylinder body, be provided with top cover (30) in the air cavity (31), push rod (32) in the air cavity (31) is provided with pull back spring (36), the cylinder body of sap cavity (28) is provided with blow off valve (37), the other end that connects the attached pump push rod (32) of top cover (30) links to each other with brake shoe (34), and the other end of brake shoe (34) is connected with pillar (11) on being fixed on vehicle frame, brake facing (33) is installed on the brake shoe (34), hydraulic pipe (4) one ends are connected with the sap cavity (25) of main pump, and the other end is connected with the sap cavity (28) of two attached pumps.Leather cup (22) in the main pump (8) is fixed in the cylinder body of main pump (8) by hollow bolt (18), and the leather cup (27) in the attached pump (3) is fixed in the cylinder body of attached pump (3) by hollow bolt (35).
