CN203248571U - Full-disc type anti-lock brake - Google Patents

Abstract

The utility model discloses a full-disk anti-lock brake, in particular to a brake block and a brake caliper body structure in a floating caliper full-disk brake. The utility model comprises a fixed disk, a moving disk, a brake caliper body, a spline brake shaft, a piston, a brake caliper body gear, and a rotating speed control pinion gear. When braking, the hydraulic pressure pushes the movable fixed disc to move in the normal direction to contact with the movable disc. In a short time, all the fixed discs and the movable disc are in contact with each other under the action of hydraulic pressure. When braking, the brake ring keeps in contact with the brake disc, but it can rotate around the center axis of the wheel under the control of the turbine speed controller, that is, to give the moving disc a certain speed, thereby realizing the "anti-lock braking" effect. Purpose. It not only reduces the vibration of the driver's feet during braking, but also reduces the high temperature generated during braking, and at the same time achieves the purpose of anti-locking.

Description

A kind of complete-disc skid control brake

Technical field

The utility model relates to break, more specifically relates to brake slipper and braking clamp body structure in a kind of floating clamp complete disc brake.

Background technique

Even although the anti-lock effect of existing antilock braking system (ABS) can, also existing some shortcomings aspect driver's the operation comfort, and when braking, can produce high temperature, thereby causing the to a certain degree reduction of Braking efficiency.Because existing anti-lock is " intermittence " braking, namely braking process be equivalent to by brake slipper and brake disc repeatedly of short duration friction comprehensively form.Therefore, this mode can make the driver experience to a certain degree vibrations, thereby affect to a certain extent travelling comfort, and because brake slipper and the friction disk area of contact of existing floating caliper type brake are very little, and the braking force that stops wheel to be rotated further provides fully thus, so the frictional force that unit area is born on the surface of contact is very large.So when each brake slipper and brake disc friction, brake block can temperature sharply raises owing to rub.

Summary of the invention

In order to address the above problem, the utility model aims to provide a kind of new brake structure, is used for solving the deficiency of existing mode of braking: the high temperature of the vibrations of driver foot and braking moment etc.

The important component part of the utility model patent: fixed disk, moving disk, braking clamp body, spline brake axle, piston, braking clamp body gear, rotating speed control small gear gear.During braking, thus hydraulic pressure try hard to recommend movable fixed disk normal direction and move with moving disk and contact, all fixed disks and moving disk are in contact with one another under the effect of hydraulic coupling in the short time.Trig loop and brake disc keep in touch during braking, but can rotate around the wheel center axle under the control of rotational speed of water turbine controller, namely give the moving certain rotating speed of disk, realize thus the purpose of " ABS (Anti-lock Braking System) ".The vibratory sensation of driver foot can reduce again the high temperature that produces when braking when both having reduced braking, had also realized simultaneously the purpose of anti-lock.

The beneficial effects of the utility model are: the vibratory sensation that reduces driver foot.Because the way of contact during braking becomes existing " continuity " braking by original " intermittence " braking, brake slipper constantly " stepping up " and " loosening " process have been avoided.Thereby the vibratory sensation that has brought when having eliminated braking.The high temperature that produces when reducing braking.Because area of contact is modified into the present trig loop around the wheel center axle by original fan-shaped brake block piece.So so area of contact strengthens the high temperature that produces in the time of can reducing braking, reduce the thermal expansion amount on the brake disc through-thickness.General not friction helps gesture effect, brake efficiency to be subjected to the impact of friction factor less, and Braking efficiency is more stable.

Embodiment

By reference to the accompanying drawings structural principle of the present utility model and working principle are specifically described:

As shown in Figure 1, the utility model patent complete-disc disc brake with floating caliper comprises: fixed disk 1, moving disk 2, piston 3, braking clamp body 4, spline brake axle 5, braking clamp body gear 6, rotating speed control small gear 7, water turbine 8, liquid input tube 9, rotational speed of water turbine controller 10, liquid output pipe 11, oil hydraulic cylinder control device 12.

As shown in Figure 2, described fixed disk 1 is provided with circular friction plate in the one side towards moving disk 2, and the excircle of fixed disk 1 is processed to external splines, a processed manhole in the middle of the fixed disk 1.Wherein lean on into four piston 3 discs of circle and dish of deciding of piston and be connected as a single entity.Fixed disk 1 can move in the wheel normal orientation under the promotion of hydraulic coupling, can relatively rotate around spline brake axle 5 simultaneously.

As shown in Figure 3, described moving disk 2 inner circumferences are processed to internal spline, and excircle is processed to manhole.

As shown in Figure 4, moving disk 2 does not contact with fixed disk 1 when original state.

As shown in Figure 5, because the effect of hydraulic coupling, all fixed disks 1 and moving disk 2 are clamped by hydraulic coupling during braking, produce braking moment with fixed disk 1 switched in opposite at moving disk 2, impel automobile brake.

Working procedure of the present utility model is, during braking, thereby hydraulic coupling promotion fixed disk 1 normal direction moves with moving disk 2 and contacts, all fixed disks 1 are in contact with one another under the effect of hydraulic coupling with moving disk 2 in short time, because very large frictional force is arranged between the two, fixed disk 1 has the trend of servo-actuated disk 2 rotations.This moment, rotational speed of water turbine controller 10 control liquid entered water turbine 8 from liquid input tube 9, because liquid is to the hydraulic coupling of water turbine 8 blades, so output shaft can produce very high pulling torque.Moment of torsion passes to rotating speed control small gear 7 again, and then passes to braking clamp body gear 6.Because braking clamp body gear 6 and braking clamp body 4 be for being rigidly connected, and braking clamp body 4 and fixed disk 1 are inside and outside spline joint.So moment of torsion further passes to fixed disk 1 by braking clamp body 4, this moment of torsion is used for offsetting the rotation trend of fixed disk 1 servo-actuated disk 2.Because fixed disk 1 tightly fits together under the effect of hydraulic coupling with moving disk 2, the rotational velocity of therefore moving disk 2 is also owing to surface friction drag descends, so the rotating speed of spline brake axle 5 is corresponding decline also, because wheel and spline brake axle 5 same rotating speeds, so also corresponding decline of vehicle wheel rotational speed.Reach thus the purpose of braking.

When soon locking of vehicle, rotational speed of water turbine controller 10 reduces the liquid that enters water turbine 8, therefore the corresponding minimizing of moment of torsion of water turbine output shaft, rotating speed control small gear 7 passes to the also corresponding minimizing of moment of torsion of braking clamp body gear 6, and then braking clamp body 4 is passed to the also corresponding minimizing of moment of fixed disk 1.Ground passes to moving disk 2 in the face of the tangential friction force of wheel by spline brake axle 5.Because this moment, braking clamp body 4 passed to the moment minimizing of fixed disk 1, be not enough to face evenly the tangential friction force of wheel, so wheel has certain rotating speed, control flows into the difference of amount of liquid of water turbine and difference to the rotating speed of wheel according to rotational speed of water turbine controller 10.Reach therefrom the purpose of anti-lock.
