Abstract
The invention discloses a fixed caliper disc brake with an electromagnet. The fixed caliper disc brake comprises brake calipers and a brake disc, wherein the brake calipers stretch over the two sides of the brake disc, and are fixedly connected to an outer vehicle frame; by taking the brake disc as the center, the brake calipers are symmetrically provided with two piston cavities; armatures capable of moving back and forth along the piston cavities are arranged in the piston cavities; one side, facing towards the brake disc, of each armature is connected with a brake pad; the other sides of the armatures are provided with clamping slots; and magnet exciting coils are arranged in the clamping slots. The fixed caliper disc brake has the effects that: the armatures are arranged at the two sides of the brake disc, and the magnet exciting coils are arranged in the armatures, so that when the magnet exciting coils are electrified, the armatures become electromagnetic blocks with magnetism, and drive the brake pads to move towards the brake disc, thereby realizing braking. Compared with a mode that a conventional fixed caliper disc brake enables the brake pads to move towards the brake disc through a hydraulic pushing piston, the scheme adopts an electromagnetic system to replace a complex hydraulic system, and therefore, the fixed caliper disc brake provided by the scheme is simple in structure and is reliable in performance.
Description
Technical field
The present invention relates to disc brake with fixed caliper, be specially a kind of disc brake with fixed caliper with electromagnet.
Background technique
Rotatable member in disk type braker friction pair is with the rosette of end face work, is called brake disc.Friction element produces braking from both sides clamping brake disc.Fixed element then has various structures form, disk type braker can be divided into caliper disc and complete-disc two class substantially.
Caliper disc brake can be divided into by the structural type of brake calipers determines caliper disc and floating caliper type disc two kinds, in the disc brake with fixed caliper used at present, can move to brake disc to make the brake slipper of brake disc both sides simultaneously, the brake fluid runner crossing over brake disc must be set in brake calipers, in this, disc brake with fixed caliper needs to set up extra hydraulic system, and this will increase the complexity of whole braking system undoubtedly.
Summary of the invention
The invention is intended to provide a kind of needs to set up extra hydraulic system, and structure is simple, the disc brake with fixed caliper with electromagnet of reliable performance.
The disc brake with fixed caliper with electromagnet in this programme, comprise brake calipers and brake disc, brake calipers is across being fixedly connected with outside vehicle frame in brake disc both sides, brake calipers is symmetrically arranged with centered by brake disc two piston cavity, being provided with in piston cavity can along the reciprocating armature of piston cavity, armature is connected with brake slipper towards the side of brake disc, and the opposite side of armature offers draw-in groove, is provided with field coil in draw-in groove.
The principle of this programme is: when driver steps on while brake petal carries out braking, pass into electric current in field coil respectively to the brake disc left and right sides simultaneously, armature will be made after field coil passes into electric current to become the magnetic electromagnetic block of tool, now armature produces magnetic force to brake disc, because brake disc is fixing, the armature of the brake disc left and right sides drives brake slipper to move to brake disc direction along piston cavity simultaneously, until the brake slipper of brake disc both sides offsets with brake disc simultaneously, under the frictional force effect of brake disc and brake slipper, brake disc speed stops gradually.
The effect of this programme is: by arranging armature in brake disc both sides, in armature, field coil is set, when field coil is energized, armature becomes the magnetic electromagnetic block of tool and drives brake slipper to move realization braking to brake disc direction, this programme and traditional disc brake with fixed caliper by hydraulic drive piston make mode from brake slipper to the movement of brake disc direction compared with, this programme adopts electromagnetic system to replace complicated hydraulic system, therefore the structure of this programme is simple, reliable performance.
Further, in order to upon completion of the braking, armature can drive brake slipper to be separated with brake disc, and also have extension spring bottom piston cavity, extension spring one end and piston cavity offset, and the extension spring the other end and armature offset.
Further, armature is also provided with the boss that can be used for positioning armature, after braking completes, armature drives brake slipper to be separated with brake disc under the effect of extension spring, until boss on armature and brake calipers offset.
Further, the surrounding of brake calipers has the circular arc chamfering preventing stress from concentrating, brake calipers is together with outside Frame Welding, the stress that circular arc chamfering can effectively reduce in brake calipers surrounding is concentrated, brake calipers 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 the embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: brake disc 1, brake calipers 2, piston cavity 3, armature 4, field coil 5, brake slipper 6, extension spring 7.
Embodiment is substantially as shown in Figure 1: the disc brake with fixed caliper with electromagnet, comprise brake calipers 2 and brake disc 1, brake calipers 2 is across the both sides at brake disc 1, left side and the outside vehicle frame of brake calipers 2 are fixed together, in the present embodiment, brake calipers 2 and outside vehicle frame are fixed together by welding, easy and simple to handle and the reliable working performance of mode of welding is stablized, and the profile line of brake calipers 2 surrounding is also provided with the circular arc chamfering preventing stress from concentrating.Brake disc 1 and outside wheel are fixed together.
Centered by brake disc 1, two piston cavity 3 are arranged with in the left and right sides of brake calipers 2, brake calipers 2 between two piston cavity 3 is also provided with the first groove, this first groove is mainly used in getting out of the way brake disc 1, the present embodiment is described with piston cavity 3 structure on the left of brake disc 1, armature 4 is provided with in piston cavity 3, armature 4 can move back and forth along piston cavity about 3, draw-in groove is offered in the left side of armature 4, draw-in groove place is provided with field coil 5, in the present embodiment, field 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, also boss is provided with on the right side of armature 4, the height of this boss above-below direction is greater than the high speed of piston cavity 3 above-below direction, this boss when armature 4 resets for carrying out position restriction to armature 4.
Brake slipper 6 is also connected with on the right side of armature 4 boss, brake slipper 6 adopts gluing mode to be connected with armature 4 boss, during braking, the brake slipper 6 of brake disc 1 left and right sides offsets with brake disc 1 simultaneously, and brake disc 1 realizes fast braking under the frictional force effect of both sides brake slipper 6.
Also be provided with extension spring 7 in the bottom of piston, left end and the piston cavity 3 of extension spring 7 offset, and right-hand member and the armature 4 of extension spring 7 offset, during braking, the active force that armature 4 overcomes extension spring 7 drives brake slipper 6 to move to brake disc 1 direction, and after having braked, extension spring 7 makes armature 4 drive brake slipper 6 to be separated with brake disc 1.
