Description
Technical field
Thereby the present invention relates to make a pair of brake shoe clamp the jaw type non-excitation actuating break that brake disc is braked by the elastic force of compression helical spring, relate in particular to and make brake shoe from mechanism that brake disc leaves when braking discharges.
Background technique
As existing this non-excitation actuating break, in for example opening in fact clear No. 51-110185 (document 1), real public clear No. 57-36833 (document 2), U. S. Patent the 7th, 438,162 (document 3), record was arranged.The disclosed non-excitation actuating break of document 1 comprises covering a brake disc peripheral part part that the cross section is the brake calipers of C word shape.With the table of brake disc on brake calipers, a part that face is relative in the inside, formed by the pincers body that contains brake shoe; The part relative with another side formed by field core.
Brake calipers is supported by the fulcrum that extends on the axial direction of brake disc, can move freely to axial direction.In addition, being constructed as follows of brake calipers: leave at the pincers body on the direction of brake disc and be subject to discharging the elastic force that produces with spring, do not applied under the state of power from armature side described later at brake calipers, use elastic force and the stopper butt of spring by release.Under the state of brake calipers and stopper butt, form the gap between the brake shoe of pincers body and brake disc.
Field core comprises field coil, supports simultaneously armature with can move freely, can and brake disc between to-and-fro motion.On the end face relative with brake disc on armature, brake shoe is set.In addition, field core comprises the compression helical spring of armature to the brake disc side application of force.
In the non-excitation actuating break that so consists of, do not produce at field coil under the state of excitation, armature is because the elastic force of compression helical spring moves to the brake disc side, and the brake shoe of armature pushes brake disc.Meanwhile, brake calipers is compressed helical spring reaction force, leaves the direction of brake disc at field core, namely clamps on the direction of body near brake disc, resists described release and moves with the elastic force of spring.Due to the movement of brake calipers, the brake shoe extruding brake disc of pincers body.Its result, brake disc are braked the pad extruding from both sides, brake disc is braked.
On the other hand, the non-excitation actuating break produces excitation by field coil, makes armature be adsorbed by field core, and the brake shoe of armature leaves from brake disc.Meanwhile, brake calipers is disappeared to the active force (reaction force of compression helical spring) of pincers body near the direction of brake disc.Due to the disappearance of this power, the elastic force that brake calipers is released with spring pushes, and moves to stopper along the direction opposite with the movement direction of armature to connect, and the brake shoe of pincers body leaves from brake disc.The brake shoe that this moment, brake calipers moved to both sides is all from neutral position that brake disc leaves.
Therefore, the non-excitation actuating break, due under brake release state, the brake shoe on both sides can not contact with the brake disc in rotation, so in the so-called idle running abrasion of the upper generation of the friction facing (friction means) of brake shoe, because idle running abrasion brake shoe does not generate heat.
On the non-excitation actuating break, when above-mentioned braking discharges, the gap that forms between brake disc and two braking pads, approximately 1/2 of the space that forms between field core and armature when being braking.
The non-excitation actuating break that document 2 is put down in writing, its braking make neutral mechanism that brake calipers moves to the neutral position and document 1 put down in writing when discharging non-excitation actuating break is different.In the non-excitation actuating break of document 2 records, other structure adopts the structure identical with the non-excitation actuating break of document 1 record.
Neutral mechanism is by being arranged at the push rod on armature and consisting of with the stopper of push rod butt.Vertical being located on armature of push rod extended to a side opposite with brake disc, connects field core and gives prominence to outside field core.From the length of the outside part of giving prominence to of field core, elongated when braking discharges relatively on bar.
Stopper consists of with the fulcrum one of supporting brake calipers with moving freely, with immovable state configuration in the position relative with bar.The space that forms between field core and armature when the ratio that the interval between stopper and push rod forms is braked is short.That is, push rod and stopper butt when braking discharges are restricted to the movement of the field core side of armature, and field core (brake calipers) is to direction (brake disc side) movement near armature.When therefore, braking discharges, the brake shoe of the brake shoe of armature and pincers body leaves respectively brake disc.
The non-excitation actuating break that document 3 is put down in writing, its braking make brake calipers move when discharging neutral mechanism is different from the non-excitation actuating break of document 1 record.In the non-excitation actuating break of document 3 records, other structure all adopts the structure identical with the non-excitation actuating break of document 1 record.
The disclosed neutral mechanism of document 3, it consists of employing: be delivered to brake calipers by discharging the power that will act on armature with bar when braking discharges, brake calipers is moved to the direction opposite with armature.Discharge and use bar, be fixed in the 1st arm on armature by an end, and an end is fixed in the 2nd arm on brake calipers, and be connected support part's formation of the other end that connects two arms.
In document 3, disclose as 2 kinds that support to discharge with the bar structure and supported structure.The 1st supports to be configured to: support part rotates by friction means and freely is supported on fulcrum, and this fulcrum is supported brake calipers with can move freely.The 2nd supports to be configured to: the 3rd bent arm is set in support part, and the 3rd arm extends abreast with two arms between two arms, and the front end of the 3rd arm is fixed in immovable support with on support.
Possessing release with on the non-excitation actuating break of bar, when braking discharged, because armature is adsorbed by field core, release used the support part of bar by the 1st arm pushing and perk, and the 2nd arm is to the direction pushing brake calipers opposite with the movement direction of armature.So, when armature is adsorbed by field core, push to the direction opposite with the movement direction of armature because brake calipers is released with bar, the brake shoe of armature leaves respectively brake calipers with the brake shoe of being located at the pincers body of brake calipers.
