When braking, close drainback passage, by being connected in the outer hydraulic system of oil inlet passage fluid is pressed in the piston cavity by oil inlet passage, because of between piston and the piston cavity by the Sealing sealing, so fluid promote piston and with braking plate side shifting outside piston cavity of its axial restraint.When braking plate contacts with brake disc, the braking beginning.When end of braking, stop delivering oil in piston cavity, open drainback passage, fluid flows out from drainback passage, replys original state.
In above-mentioned a kind of hydraulic braking pincers, the caliper place in the described drainback passage outside is connected with a scavenger valve, and described scavenger valve can be subjected to brake petal control and open or cut out.When stepping on brake petal when car brakeing, scavenger valve is subjected to brake petal control and cuts out; When brake petal lifted, scavenger valve was opened again.
In above-mentioned a kind of hydraulic braking pincers, described piston cavity inboard also offers a vent hole that is communicated to the caliper outside, is connected with one on the described vent hole and can controls the venting part that vent hole is opened or closed.Can the air in the piston cavity be emitted by vent hole by operation venting part before the vehicle driving or after travelling, guarantee vacuum in the piston cavity.
In above-mentioned a kind of hydraulic braking pincers, described venting part is a bleed screw.
In above-mentioned a kind of hydraulic braking pincers, be connected with a serum cap on the caliper in the described vent hole outside.Serum cap is used to prevent that extraneous flue dust from entering vent hole.
In above-mentioned a kind of hydraulic braking pincers, be connected with a dust-proof cover between described piston exterior edge face and the caliper.
In above-mentioned a kind of hydraulic braking pincers, described dust-proof cover is that flexible material is made, and one end and above-mentioned piston exterior edge face are connected, and the other end is connected by the collar and the caliper outside, and the length of described dust-proof cover is greater than the stroke of piston.The two ends of dust-proof cover are connected with the piston exterior edge face and the caliper outside respectively, make it guarantee that extraneous flue dust can not enter piston cavity with the motion campaign of piston.
In above-mentioned a kind of hydraulic braking pincers, described Sealing is a seal ring.
In above-mentioned a kind of hydraulic braking pincers, described piston exterior edge face and above-mentioned braking plate are connected.
Compared with prior art, in the caliper of this hydraulic braking pincers a piston that is subjected to HYDRAULIC CONTROL SYSTEM is only arranged, simple in structure, even break down, it is also comparatively convenient to keep in repair; Simultaneously, caliper peripheral hardware storing gas spare is used to detect and debug the interior vacuum condition of piston cavity, the performance reliability when having guaranteed automobile running.

Fig. 1 is the structural representation of this hydraulic braking pincers.
Fig. 2 is that this hydraulic braking clamps along the cross-sectional view that A-A did.
Among the figure, 1, caliper; 1a, piston cavity; 2, piston; 3, braking plate; 4, oil inlet passage; 6, Sealing; 8, vent hole; 9, venting part; 10, serum cap; 11, dust-proof cover; 12, collar.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1 and Figure 2, this hydraulic braking pincers comprise caliper 1 with piston cavity 1a, are arranged at piston 2 and braking plate 3 in the piston cavity 1a, and braking plate 3 is connected with the exterior edge face of piston 2, seals by seal ring between piston 2 and the caliper 1.Also offer the oil inlet passage 4, drainback passage and the vent hole 8 that all are communicated to caliper 1 outside on the caliper 1 of piston cavity 1a inboard.
For convenient control, be sealedly connected with a scavenger valve and this scavenger valve and drainback passage internal communication at caliper 1 place of drainback passage outer end; Caliper 1 place of vent hole 8 outer ends is connected with the venting part 9 that can control vent hole 8 closure or openness.In the present embodiment, drainback passage connects scavenger valve, fuel tank, electric pump and oil inlet passage 4 successively and forms the loop; Scavenger valve is the automatically reset normally open solenoid valve of energy, and this solenoid valve is controlled by the action of brake petal; Venting part 9 is a bleed screw.
When normal vehicle operation, solenoid valve is in opening state, the conducting of fluid loop, and braking plate 3 and piston 2 are in the state away from brake disc; When the driver steps on brake petal, the control circuit closure of solenoid valve, the solenoid valve energising is closed, and drainback passage is blocked, and electric pump provides power that fluid is input in the piston cavity 1a, promotes piston 2 and outwards moves.At this moment, braking plate 3 moves with piston 2 and brakes until contacting with brake disc.
Work as end of braking, when the driver decontrols brake petal, electric pump quits work, the control circuit of solenoid valve disconnects, and solenoid valve is replied opening state, and fluid returns fuel tank by drainback passage, fluid reduces the active force of piston 2, piston 2 is again in the 1a of return piston chamber, and braking plate 3 is away from brake disc, end of braking.
For the vacuum state in the piston cavity 1a that guarantees vehicle in the process of moving, can vent hole 8 be opened by bleed screw before vehicle driving or after travelling, the fluid consecutive hours when flowing out in vent hole 8 shows not contain air in the piston cavity 1a; When the fluid that flows out is intermittent, show that piston cavity 1a contains air.
In addition, enter in the piston cavity 1a of caliper 1, connect a serum cap 10 in the outside of vent hole 8 for preventing extraneous flue dust; Be connected the dust-proof cover 11 that a flexible material is made between piston 2 exterior edge faces and caliper 1 outside, these dust-proof cover 11 1 ends and piston 2 exterior edge faces are connected, and the other end is fixed on caliper 1 outside by collar 12, and its spread length is greater than the stroke of piston 2.In the present embodiment, dust-proof cover 11 uses nylon material to make.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
