Abstract
The utility model discloses a full-disc type anti-lock brake and particularly relates to a braking block and a braking tong body structure in a floating tong full-disc type brake. The full-disc anti-lock brake comprises fixed circular discs, movable circular discs, a braking tong body, a spline braking shaft, a piston, a braking tong body gear and a rotating speed control pinion gear. During the braking, hydraulic pressure pushes the movable and fixed circular discs to do heave motion to be in contact with the movable circular discs, and all of the fixed circular discs and the movable circular discs are in mutual contact under the effect of the hydraulic pressure in a short time. During the braking, a braking ring maintains the contact state with a braking disc but can rotate around a center shaft of a wheel when controlled by a water turbine rotating speed controller, i.e., the movable circular discs rotating at a certain speed, so the anti-lock braking goal is realized. The vibration feeling of the foot part of a driver during the braking is reduced, and high temperature generated during the braking can also be lowered. Meanwhile, the anti-lock goal is realized.

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.
