The utility model discloses an effect is: through setting up the armature in brake disc both sides, set up excitation coil in the armature, when excitation coil switched on, the armature became to have magnetic electromagnetism piece and drive the brake pads and moves to the brake disc orientation and realize the braking, and this scheme and tradition are decided disc brake and are promoted the piston through hydraulic pressure and make the brake pads compare to the mode that the brake disc orientation moved, and this scheme adopts electromagnetic system to replace the hydraulic system of complicacy, so the simple structure of this scheme, dependable performance.
Description
Technical field
This utility model relates to disc brake with fixed caliper, is specially a kind of disc brake with fixed caliper with electric magnet.
Background technology
Rotation element in disk brake friction pair is with the rosette of end face work, is called braking dish.Friction element clamps braking dish from both sides and produces braking.Retaining element then has various structures form, and disk brake generally can be divided into caliper disc and complete-disc two class.
Spot-type disc brake can be divided into by the structural shape of caliper determines caliper disc and floating caliper type disc two kinds, in currently used disc brake with fixed caliper, in order to make the brake block of braking dish both sides to move to braking dish simultaneously, the brake fluid runner crossing over braking dish must be set in caliper, in this, disc brake with fixed caliper needs to set up extra hydraulic system, and this will increase the complexity of whole brakes undoubtedly.
Utility model content
This utility model is intended to provide a kind of need not set up extra hydraulic system and the disc brake with fixed caliper with electric magnet of simple in construction, dependable performance.
The disc brake with fixed caliper with electric magnet in this programme, including caliper and braking dish, caliper is across in braking dish both sides and fixing with outside vehicle frame be connected, caliper is symmetrically arranged with two plunger shaft centered by braking dish, being provided with in plunger shaft can along the reciprocating armature of plunger shaft, armature is connected to brake block towards the side of braking dish, and the opposite side of armature offers draw-in groove, is provided with magnet exciting coil in draw-in groove.
The principle of this programme is: while driver's brake pedal is braked, pass into electric current respectively in the magnet exciting coil of the braking dish left and right sides simultaneously, magnet exciting coil will make armature become the magnetic electromagnetic block of tool after passing into electric current, now braking dish is produced magnetic force by armature, owing to braking dish is fixing, the armature of the braking dish left and right sides drives brake block to move to braking dish direction along plunger shaft simultaneously, until the brake block of braking dish both sides offsets with braking dish simultaneously, under the frictional force effect of braking dish and brake block, braking disc speed degree tapers off.
The effect of this programme is: by arranging armature in braking dish both sides, magnet exciting coil is set in armature, when magnet exciting coil is energized, armature becomes the magnetic electromagnetic block of tool and drives brake block to move realization braking to braking dish direction, compared with the mode that this programme and tradition disc brake with fixed caliper make brake block move to braking dish direction by hydraulic drive piston, the hydraulic system that this programme employing electromagnetic system replacement is complicated, therefore the simple in construction of this programme, dependable performance.
Further, in order to upon completion of the braking, armature can drive brake block to separate with braking dish, also having extension spring bottom plunger shaft, extension spring one end and plunger shaft offset, and the extension spring other end and armature offset.
Further, armature being additionally provided with the boss that can be used for that armature is positioned, after braking completes, armature drives brake block to separate with braking dish under the effect of extension spring, until the boss on armature and caliper offset.
Further, the surrounding of caliper has the circular arc chamfering preventing stress from concentrating, caliper is together with outside Frame Welding, circular arc chamfering can effectively reduce the stress in caliper surrounding and concentrate, caliper welds with outside vehicle frame simultaneously, the mode of welding is easy to operate, and reliable working performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: braking dish 1, caliper 2, plunger shaft 3, armature 4, magnet exciting coil 5, brake block 6, extension spring 7.
Embodiment is substantially as shown in Figure 1: have the disc brake with fixed caliper of electric magnet, including caliper 2 and braking dish 1, caliper 2 is across the both sides at braking dish 1, the left side of caliper 2 is fixed together with outside vehicle frame, in the present embodiment, caliper 2 is fixed together by welding with outside vehicle frame, the mode of welding is easy and simple to handle and reliable working performance stable, is additionally provided with the circular arc chamfering preventing stress from concentrating on the contour line of caliper 2 surrounding.Braking dish 1 is fixed together with outside wheel.
Centered by braking dish 1, two plunger shaft 3 it are arranged with in the left and right sides of caliper 2, caliper 2 between two plunger shaft 3 is additionally provided with the first groove, this first groove is mainly used in getting out of the way braking dish 1, the present embodiment illustrates with plunger shaft 3 structure on the left of braking dish 1, armature 4 it is provided with in plunger shaft 3, armature 4 can move back and forth along plunger shaft about 3, draw-in groove is offered in the left side of armature 4, draw-in groove place is provided with magnet exciting coil 5, in the present embodiment, magnet exciting coil 5 is direct-flow magnet exciting coil, direct-flow magnet exciting coil is compared with the impact of AC excitation coil, noise is little, it is additionally provided with boss on the right side of armature 4, the height of this boss above-below direction is more than the high speed of plunger shaft 3 above-below direction, this boss when armature 4 resets for armature 4 is carried out position restriction.
It is also associated with brake block 6 on the right side of armature 4 boss, brake block 6 and armature 4 boss adopt gluing mode to be attached, during braking, the brake block 6 of braking dish 1 left and right sides offsets with braking dish 1 simultaneously, and braking dish 1 realizes fast braking under the frictional force effect of both sides brake block 6.
Be additionally provided with extension spring 7 in the bottom of piston, the left end of extension spring 7 and plunger shaft 3 offset, and the right-hand member of extension spring 7 and armature 4 offset, during braking, armature 4 overcomes the active force of extension spring 7 to drive brake block 6 to move to braking dish 1 direction, and after having braked, extension spring 7 makes armature 4 drive brake block 6 to separate with braking dish 1.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the premise without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
