Abstract
The utility model relates to a hydraulic brake with an anti-lock device for motorcycle front wheel, which comprises a main pump piston (1) on which a pressure relief hole (6) is arranged; the center of the piston (1) is provided with a through hole (7); the pressure relief hole (6) is provided with a pressure relief control device. The rear end of the through hole (7) of the main pump piston (1) is provided with inner screw threads; a valve rod (2) is arranged in the through hole (7); a sealing ring (4) is arranged in a sealing ring groove of the valve rod (2); a screw plug is connected with the piston (1) by screws through the inner screw threads in the through hole (7); a spring (3) is sheathed on the valve rod (2). The utility model has the advantages that due to the fact that the main pump piston is provided with a hydraulic control device with the pressure relief hole, the braking performance of a motorcycle front wheel can be effectively improved; the anti-lock effect is good and the cost is low.
Description
Technical field the utility model relates to the Vehicular brake device field.
Background technology is when the motor bike of hydraulic brake being installed in driving, run into emergency situation and when taking emergency braking, make the front-wheel locking owing to braking force is excessive, sometimes because of after the pollution of the braking liquid in the hydraulic brake 0.5 hole of the φ in the main pump piston hole being blocked, also can cause the front-wheel locking, this moment, front-wheel lost steering capability, very easily caused traffic accident.Excessive and make the front-wheel locking in order to solve braking force, electromagnetic type anti-lock device or motor-driven anti-lock device have been installed on the hydraulic brake of luxurious motor bike, but their technology more complicated, productive costs is high, and most consumers is difficult to accept economically.Since nineteen ninety-eight, continuous several dissimilar mechanical type anti-lock devices of releasing are made in domestic land, the use through several years, and the anti-lock DeGrain is difficult to apply.
Utility model content technical problem to be solved in the utility model is the above-mentioned deficiency of anti-lock device that overcomes existing motorcycle hydraulic drg, and a kind of motorcycle front-wheel hydraulic brake with anti-lock device that provides, it has the function of adjustment pressure, can improve the deceleration and stopping performance of motorcycle front-wheel effectively, anti-lock is effective, and is cheap for manufacturing cost.
It is as follows that the utility model solves the problems of the technologies described above the technical solution that is adopted: the motorcycle front-wheel hydraulic brake of band anti-lock device, comprise total pump piston (1), but on piston (1), have relief hole (6), the center of piston (1) has through hole (7), locates to be equipped with the pressure release control setup at relief hole (6).The pressure release control setup is by valve rod (2), spring (3), seal ring (4) and screw plug (5); Through hole (7) rear end in total pump piston (1) is provided with negative thread, valve rod (2) is installed in the through hole (7), have seal groove and spring location bank on the valve rod (2), seal ring (4) is installed in the seal groove of valve rod (2), screw plug (5) is threaded with piston (1) by the negative thread in the through hole (7), and spring (3) is enclosed within on the valve rod (2), and an end withstands on the bank of spring location, the other end contacts with screw plug (5), and the oil inlet of through hole (7) communicates with the high pressure chest of master cylinder; The oil inlet of relief hole (6) communicates with through hole (7), and its oil outlet communicates with the low-pressure cavity of master cylinder.Valve rod (2) and seal ring (4) can be replaced by globe valve 8 or cone valve 9.
The technique effect that the utility model adopts above-mentioned technical solution to reach is: owing to designed the hydraulic regulating device of band relief hole on total pump piston, its principle of work is: the glancing impact hydraulic pressure rises, compression spring, valve rod is moved backward, when wheel lockup, brake-pressure reaches sets the pressure release value, and seal ring retreats and slips over relief hole, the high pressure chest of master cylinder communicates by relief hole with low-pressure cavity, thereby make pressure decay, locked wheel recovers running, at this moment, because pressure reduces, spring promotes valve rod and moves ahead, and seal ring moves ahead and slips over relief hole again, and the high pressure chest of master cylinder and the sealed circle of path of low-pressure cavity are disconnected, pressure rises again wheel is braked, so circulation more than four times in each braking, thereby it has the function of adjustment pressure, can improve the deceleration and stopping performance of motorcycle front-wheel effectively, anti-lock is effective, because of its need are transformed a little to existing total pump piston, add a control cock and get final product, thereby cheap for manufacturing cost.
Description of drawings Fig. 1 is the utility model total pump piston structural representation.Fig. 2 is the utility model replaces valve rod with globe valve a structural representation.Fig. 3 is the utility model replaces valve rod with cone valve a structural representation.Fig. 4 is the utility model structural representation sketch.
The existing motorcycle front-wheel hydraulic brake of the specific embodiment mainly is made up of main pump, main pump piston (1), wheel cylinder, wheelcylinder piston (10) and the hydraulic oil pipe that is connected main pump and wheel cylinder (11), only needing to have total pump piston now during processing the utility model transforms a little, on piston, open relief hole, the hole is opened at the piston center, the connection mode installation of valve rod, spring, seal ring and screw plug by specification and Figure of description is got final product, improved total pump piston is installed equally with the mode of former total pump piston during use, and the adjusting of pressure release value is undertaken by the adjusting screw plug.
Claims (3)
1, the motorcycle front-wheel hydraulic brake of band anti-lock device comprises total pump piston (1), it is characterized in that having relief hole (6) on piston (1), and the center of piston (1) has through hole (7), locates to be equipped with the pressure release control setup at relief hole (6).
2, the motorcycle front-wheel hydraulic brake of band anti-lock device according to claim 1 is characterized in that the pressure release control setup is by valve rod (2), spring (3), seal ring (4) and screw plug (5); Through hole (7) rear end in total pump piston (1) is provided with negative thread, valve rod (2) is installed in the through hole (7), have seal groove and spring location bank on the valve rod (2), seal ring (4) is installed in the seal groove of valve rod (2), screw plug (5) is threaded with piston (1) by the negative thread in the through hole (7), and spring (3) is enclosed within on the valve rod (2), and an end withstands on the bank of spring location, the other end contacts with screw plug (5), and the oil inlet of through hole (7) communicates with the high pressure chest of master cylinder; The oil inlet of relief hole (6) communicates with through hole (7), and its oil outlet communicates with the low-pressure cavity of master cylinder.
