Embodiment
The practical implementation of the caliper disc brake of symmetry braking of the present invention is Fig. 1, Fig. 2, shown in Figure 3 for example; It comprises base 1; The left brake arm group that is provided with two relative engagement 2 and right brake arm group 3 at relative interval, both sides on the base 1; The lower end of two brake arm groups 2,3 is hinged on respectively on the base 1, and the upper end of two brake arm groups 2,3 is in transmission connection on power mechanism respectively.Two brake arms 2,3 are formed by the brake arm plate that is provided with at interval in pairs; Between two brake arm plates, be respectively arranged with brake calipers; With left brake arm 2 is example; As shown in Figure 2, left brake arm 2 is made up of the two brake arm plate 2-1 and the 2-1 of relative spacing setting respectively, and the lower end of two brake arm plate 2-1,2-2 is coaxial respectively to be hinged on the base 1; The upper end of two brake arm plate 2-1,2-2 connects through connecting pin 4-1; Radially install at the middle part of this connecting pin 4-1 and to be fixed with connecting rod 4, the middle part between two brake arm plate 2-1,2-2 is provided with brake calipers 8, and brake calipers 8 comprises caliper 8-1, the 8-2 of two corresponding matching; Two caliper 8-1,8-2 are assemblied on the base 1 through bearing pin 9 rotations respectively away from an end of brake disc; The axis of this bearing pin 9 is simultaneously vertical with base 1 with brake disc, and the corresponding friction lining that is used for the brake disc frictional fit that is provided with on the opposing side of the other end of two caliper 8-1,8-2 offers inclined-plane 2-3 at two brake arm plate 2-1,2-2 respectively on the inner side edge edge of brake calipers 8; With the last roller 8-4 that rolls and cooperate with inclined surface 2-3 that is rotatably equipped with respectively of two brake arm plate 2-1, the caliper 8-1 of 2-2 relative engagement, 8-2, the bearing pin 9 of the rotating shaft 8-3 of each roller 8-4 and two caliper 8-1,8-2 laterally arranges.In actual the use; At two caliper 8-1, the last automatic reset device (not looking out among the figure) that also is respectively arranged with of 8-2; This automatic reset device can adopt and be connected the torsion spring between base 1 and each caliper or be arranged on spring or the reed between the two relative calipers; Its mounting type repeats no more for well known to a person skilled in the art routine techniques here.The structure of right brake arm 3 is identical with left brake arm 2, and its concrete structure can be with reference to the description of left brake arm 2.
This power mechanism comprises the brake spring mechanism 6 and pusher 7 that an end of base 1 connects through bearing; Be connected with leverage 5 on the pto of pusher 7; Left side brake arm group 2 is in transmission connection with this leverage 5 through the connecting rod 4 that connects on it; Connecting rod 4 is hinged with this leverage, and is hinged through connecting pin and leverage 5 in the two brake arm plates upper end of right brake arm group 3.In the present embodiment, brake spring mechanism 6 by two be symmetricly set on leverage 5 both sides the brake spring assembly form.
Under normal conditions, power mechanism 7 energising actions promote 2,3 actions of leverage 5 drives two brake arm groups and separate to both sides, and the brake calipers 8 that is in transmission connection with two brake arm groups 2,3 is relaxation state, and brake disc rotates; During braking; Power mechanism 7 outage, the descending drive two brake arm groups 2,3 of an end of 6 pull lever mechanisms 5 of brake spring mechanism each other near, each the brake arm plate on the two brake arm groups 2,3 moves in opposite directions; The roller of installing on the inclined-plane of each brake arm plate inside edge and the corresponding caliper rolls and cooperates; The inclined-plane produces squeezing action to the roller of caliper, orders about corresponding two calipers each other near clamping brake disc, realizes braking.
Because the utilization of technique scheme, the present invention has compared with prior art had the advantage of arm disk type braker and caliper brake concurrently, and very quantum jump is arranged on structure, performance and principle are used:
1., the application of new transmission principle; Each caliper of its brake calipers rotates through bearing pin respectively and is assemblied on the base 1; Each rotates folding around its bearing pin to caliper under the driving on the inclined-plane that is provided with on the corresponding brake arm; The radially band-type brake power that brake arm is produced changes into the axial clamping force of caliper cleverly, realizes the bilateral symmetry braking to brake disc, has optimized the force structure of break.
2., the present invention adopts the Chinese style structural design, abandons the offset structure of conventional arm pan brake in the past, realizes that spring force acts on the center, brake arm do not produced torsion, thereby prolonged the working life of brake arm rotary axle box greatly, improved transmission efficiency.
3., novel mechanical structure; Adopt the design of the symmetrical application of force, symmetry braking; Make it in less spatial position, can realize bigger braking moment; The Force Optimal configuration of force transferring structure system reduces the rotary inertia of coupling coupling greatly, makes bearing and coupling life-span also can prolong greatly.
4., adopt the arm pan brake of symmetry braking can realize the easily symmetry braking of separate unit break, simultaneously braking force is affacted on the brake disc through two symmetric points, thus the radial effect power that compensation produces the brake disc rotating shaft.
5. compare with conventional hydraulic pusher arms disk type braker; Its structure width is dwindled greatly, thereby the coupling between motor and speed reducer can be shortened greatly, and structure is compact more; Increased maintenance and space, aisle accordingly, made the layout in the equipment machine room more reasonable.
The present invention is not limited to the foregoing description; The switching-over driving mechanism that the above-mentioned radial motion with brake arm converts the axial motion of brake calipers into also can adopt other equivalent driving mechanism to substitute; For example: the mode that above-mentioned Wedge mechanism also can adopt traditional voussoir to match with slide block; Voussoir is fixed on caliper or the brake arm plate, and the inclined-plane of this voussoir is towards the brake arm plate or the caliper of correspondence, and the slide block that the inclined-plane with voussoir is slidingly matched is set on the brake arm plate of correspondence or caliper; Or with each caliper and corresponding bearing pin employing fixed connection mode; And rotate fit with adopting between each bearing pin and the base; The coaxial gear that is equipped with on bearing pin; On the brake arm plate inwall of correspondence, be fixed with tooth bar with this meshed transmission gear; It is the arc-shaped structure in the center of circle that this tooth bar adopts the rotating shaft with the brake arm plate, and brake arm plate meshing transmission structure through gear rack along the radially wobbling of brake disc the time drives caliper through bearing pin and rotates, and realizes the clamping of brake calipers and loosens.These equivalent switching-over drive mechanisms all are that those skilled in the art is easy to and will expects, all within protection scope of the present invention.
