Handle and cable wire column cap are connected respectively to the cable wire both ends, and the cable wire column cap is installed at the piston crown. The cable wire passes brake caliper, arranges in the circumference slot of piston crown, through cable wire column cap and hinge joint. The cylindrical through -hole clearance fit of cable wire column cap and piston crown, cable wire pulling in -process, the corresponding rotation of cable wire column cap. During the pull -up handle, the pulling force passes to the cable wire column cap through the cable wire, acts on the piston crown, makes the piston overcome the piston seal restraint and withdraws from along the screw rod rotation, relieves the packing force to the brake pads to relieve electronic parking brake. After relaxing the handle, the piston is static under piston seal's restraint.
Description
Technical field
This utility model provides a kind of machinery releasing electronic parking Braking system, relates to automotive electronic parking system.
Background technology
Utilize the automobile that electronic brake system is braked after taking parking braking, because components and parts fault can run into the situation that Electronic Control inefficacy causes electronic brake to release.If electronic brake does not release, automobile cannot continue to travel, and can bring unnecessary trouble to driver.Being presently mainly and make Electronic Control recover usefulness or the mode of dismounting automotive wheel by maintainer on site fault clearing, releasing the piston thrust to brake block, thus releasing electronic brake.Commercially there is not yet and can release electronic brake, and simple operation, low cost, simple in construction device.
Summary of the invention
This utility model is in the market to being capable of releasing the demand of electronic brake device, it is provided that a kind of machinery releasing electronic parking Braking system, can release electronic brake when electronic parking system electronic controls to lose efficacy.
This utility model releases the machinery of electronic parking Braking system and is made up of piston 6, cable wire 5, sheath 4, cable wire stigma 14 and handle 7.Cable wire 5 one end connects handle 7, and the other end connects cable wire stigma 14, and cable wire stigma 14 is arranged in the cylindrical hole of piston 6 head.The two ends of sheath 4 are fixing, and the head of its one end is fixed on braking clamp body 2, and the other end is fixed on vehicle body.Cable wire 5 is arranged in the circumferential grooves of piston 6 head through braking clamp body 2, is connected with piston 6 by cable wire stigma 14.Cable wire stigma 14 is cylindrical, and with the cylindrical hole matched in clearance of piston 6 head, in cable wire 5 drawing process, cable wire stigma 14 rotates accordingly.
This utility model releases the machinery of electronic parking Braking system when driver's pull-up handle 7, pulling force passes to cable wire stigma 14 by cable wire 5, act on piston 6 head, make piston 6 overcome piston packing 13 to retrain to exit along screw rod 9 rotation, release the thrust to brake block 3, thus releasing electronic brake.After driver's release handle 7, piston 6 is static under the constraint of piston packing 13.
The machinery of this utility model releasing electronic parking Braking system can complete once to release the effect of electronic parking Braking system.Piston 6 is forwarded to the position before use after completing the parking braking of once releasing electronic parking system by this utility model, it is possible to again release the parking braking of electronic parking system.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
As it is shown in figure 1, the machinery that this utility model releases electronic parking Braking system is made up of piston 6, cable wire 5, sheath 4, cable wire stigma 14 and handle 7.Cable wire 5 one end connects handle 7, and the other end connects cable wire stigma 14, and cable wire stigma 14 is arranged in the cylindrical hole of piston 6 head.The two ends of sheath 4 are fixing, and the head of its one end is fixed on braking clamp body 2, and the other end is fixed on vehicle body.Cable wire 5 is connected with piston 6 by cable wire stigma 14, and in cable wire 5 drawing process, cable wire stigma 14 rotates accordingly.
As in figure 2 it is shown, cable wire 5 is arranged in piston 6 head circumferential grooves through braking inlay 2, being connected with piston 6 by cable wire stigma 14, cable wire stigma 14 is cylindrical, with the cylindrical hole matched in clearance of piston 6 head.
As it is shown on figure 3, piston 6 head has cylindrical hole, outside cylindrical hole, leave the groove that width is cable wire 5 diameter.Have, along piston 6 circumference, the groove that width is cable wire 5 diameter, be used for arranging cable wire 5.During installation, make cable wire stigma 14 be axially parallel to piston 6 axially to load in cylindrical hole, and making cable wire 5 be parallel to piston 6 radially along in groove insertion cylindrical hole, cable wire 5 can make cable wire 5 embed piston 6 head circumferential grooves together with cable wire stigma 14 half-twist again.
Under electronic brake system normal condition, power is passed to screw rod 9 by multiple-speed gear-box 10 by motor 11, controls screw rod 9 rotating, thus changing the brake force that pressure nut 8 is applied on piston 6.As shown in Figure 4, pressure nut 8 and piston 6 fit inside that outside is square, cannot rotate relative to piston 6, piston packing 13 is to piston 6 Constrained effect simultaneously, so the rotation of screw rod 9 can only drive piston 6 axial translation, under the driving of motor 11, complete applying and the releasing of electronic brake.
In Fig. 5 a) shown in, when Electronic Control lost efficacy, motor cannot drive screw rod 9 to rotate, and pressure nut 8 is added in the thrust on piston 6 and cannot cancel, and the parking braking of electronic parking system continues to keep causing that automobile cannot be driven.In Fig. 5 b) shown in, during pull-up handle 7, pulling force passes to cable wire stigma 14 by cable wire 5, act on piston 6 head, making piston 6 overcome piston packing 13 to retrain to rotate along screw rod 9 and exit, release thrust to brake block 3, braking clamp body 2 is along guide finger 12 adverse movement simultaneously, release the clamping force to braking dish 1, thus releasing the parking braking of electronic parking system.After release handle 7, piston 6 is static under the constraint of piston packing 13, will not regenerate parking-brake action.
