Description
Technical field
The utility model relates to a kind of disk type braker of electric motor car, be specifically related to a kind of can auto-compensation brake block the break of mechanical displacement after wearing and tearing.
Background technique
At present, the break hydraulic type of using on motorcycle more.The feature of hydraulic brake be braking steadily, but have unsafe hidden danger, as leakage of oil, oil pipe are aging, break etc., and cost is higher.Mechanical disc-type brake cost is lower, and braking effect is good, thereby is applicable to motorcycle and electric motor car.At present, occurred that some utilize mechanical structure to carry out the break of auto-compensation, but had following technical problem: rocker compensating gear is comparatively complicated.And after brake off, the separated return of upper and lower brake shoe is to rely on the brake disc collision effect of rotating, and there is no to arrange in addition the mechanism that makes brake shoe return, so, the poor reliability of brake off.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of mechanical disc-type brake, and its panel system actuation mechanism is simpler, the part of composition still less, thereby reduce production costs.It can make brake shoe separated return reliably, the gap that friction compensation pad wear produces in time, and it is simple in structure, and braking and releasing brake safe are reliable.
For achieving the above object, the technical solution of the utility model is: a kind of auto-compensation mechanical disc-type brake, comprise caliper, the jaw place of caliper is provided with friction plate, in caliper, be provided with braking device and blank compensation apparatus, described braking device comprises the active rotating disk that caliper inner chamber arranges, initiatively the projecting shaft of rotating disk is connected with brake rocker arm, in caliper, resonator end surface is provided with three semicircle orifices of dividing equally, the ball of same size is installed in semicircle orifice, initiatively rotating disk is provided with the conical pit corresponding with three semicircle orifices of caliper interior edge face on interior edge face, initiatively the exterior edge face of rotating disk contacts a piston, described piston external diameter is provided with a straight trough, rotation stopping screw screws in the straight trough of piston from the screw of caliper shell, the jaw place of caliper is provided with seal ring, piston external diameter is sealed, described blank compensation apparatus comprises backlash compensation screw rod, backlash compensation screw rod comprises thread section and polished end section, thread section coordinates with the tapped hole that piston interior edge face is offered, on polished rod, be arranged with torsion spring, insert in active torsion spring hole, rotating disk exterior edge face one end of torsion spring, and keep certain matching gap, initiatively rotating disk exterior edge face offers a center hole, one ball is housed in hole, ball coordinates with the top axial of backlash compensation screw rod polished rod, the center, exterior edge face of the spiro rod section of backlash compensation screw rod is provided with a deep hole, is provided with spline rubber pin in deep hole.
While adopting technique scheme, because motorcycle, electric motor car are stopping under travelling state, wheel and brake disc transfixion, between friction plate and brake disc, there is the original about 0.3～0.4mm of gap Smm(), no matter brake and take-off the brake how many times, between friction plate and brake disc, remain the about 0.3～0.4mm of original gap Smm() constant.Because active rotating disk is provided with the conical pit corresponding with three semicircle orifices of caliper interior edge face on interior edge face, when braking, brake rocker arm drives initiatively dial rotation angle [alpha], the conical surface of ball and conical pit produces and relatively moves, force initiatively rotating disk to move axially, promote piston-advance, then braked by piston promotion friction plate.Meanwhile, because insert in the torsion spring hole of active rotating disk end face one end of torsion spring, during braking, torsion spring is with the certain angle beta of active dial rotation, and the original internal diameter of torsion spring becomes large, and the torsion spring being enclosed within on backlash compensation screw rod polished rod is unclamped.Because spline rubber pin has been fixed in the exterior edge face of backlash compensation screw rod, torsion spring can not drive backlash compensation bolt rotary, can only on backlash compensation screw rod, slide.During take-off the brake, brake rocker arm drives initiatively rotating disk reversion several angle α, the torsion spring several angle β that thereupon reverses again, because insert in the torsion spring hole of active rotating disk end face torsion spring one end, and there is certain gap, initiatively rotating disk when reversion, can't drive torsion spring wrap and locking on backlash compensation screw rod, torsion spring is freely got back to home position.Upper friction plate pulls piston and backlash compensation screw axial to be repositioned to home position by return screw and return spring.
When friction disc wear Δ s, initiatively rotating disk needs the angle delta α of rotation more when braking, torsion spring also with more than rotate an angle delta β.After take-off the brake, initiatively rotating disk reverse angle is α+Δ α, and torsion spring is reverse angle β+Δ β thereupon also, and initiatively rotating disk is got back to home position together with torsion spring.In this process, torsion spring, because rotated Δ β, can be wrapped also locking on backlash compensation screw rod more, and drives backlash compensation bolt rotary Δ β.Because backlash compensation screw rod is engaged in the tapped hole that piston interior edge face offers, and piston is spacing and can not rotate by rotation stopping screw, can only move axially.The distance auto-compensation moving by piston in this time braking and the process of take-off the brake the gap that produces of the Δ s of friction disc wear, until friction disc wear is to the limit position of changing, more after renewal of facing renewal, backlash compensation screw rod is returned to home position.
Further, the jaw place of described caliper is provided with fixed plate, described fixed plate is provided with four sliding pins, two sliding pins are located at the fixed plate the other end and coordinate assembling caliper with caliper two slide openings, caliper can move axially, fixed plate other end is provided with two force-bearing pins, and coordinates in upper and lower friction plate bottom plate hole, also can move axially.Such design, during braking, braking force is born by two sliding pins that are fixed on connecting plate, and caliper only plays the effect of retardation pressure, and the sliding pin on connecting plate plays the withstand shocks effect of power of when braking.Caliper is separately provided with two holes that return springs and screw are installed, and upper friction plate, return spring, screw are coupled together by two other hole, allows its self-return aligning, and manual dexterity is safe and reliable.
Further, in the center hole that described active rotating disk exterior edge face is offered, be provided with a ball.Can avoid the end face of backlash compensation screw rod directly to contact for a long time and produce wearing and tearing with active rotating disk.
