Abstract
The invention belongs to the field of vehicle braking devices, and discloses a large-braking-force disc brake device. The large-braking-force disc brake device comprises a brake disc, a hub, a screw, a friction plate, a piston, a piston shell and a brake clamp shell. The brake disc is fixed to the hub through the screw. The cross section of the friction plate is in a trapezoid shape, and is matched with a trapezoid groove in the brake disc. The rear portion of the friction plate is connected with the piston installed in the piston shell, and the piston shell is fixed in the brake clamp shell. Due to the fact that the braking force of an existing disc brake is small and the existing disc brake cannot be used on a large vehicle, the braking stability of the large vehicle is poor. When the large-braking-force disc brake device is used, the braking force is large, the large-braking-force disc brake device can be used on the large vehicle, and the driving safety is guaranteed.
Description
Technical field
The present invention relates to a kind of large braking force disc brake device, be applicable to all kinds of large vehicle, belong to Vehicular brake device field.
Background technique
At present, disc brakes because of the advantage that its insensitivity is good, the rear rate of cooling of braking is fast and can be used in combination with the active safety technologies such as " antilock braking system (ABS) ", " body electronics stable system ", and obtains applying more and more widely.
But what use on large vehicle remains the drum brakes that performance can not show a candle to disc brakes.This is mainly because the brake disc of existing disc brakes and Friction Disk Surface are all plane, and its braking force is less, can only be applied on dilly.This causes the defect of large vehicle braking system to have:
1, lack the protection of the active safety technologies such as " antilock braking system (ABS) ", " body electronics stable system ", the Security when severe road conditions braking is not good, and vehicle body accident out of control easily occurs;
, after braking continuously, easily there is the phenomenon of braking heat fade, time serious, can braking failure be caused in 2, braking device poor cooling performance.
Summary of the invention
The technical problem to be solved in the present invention:
There is provided a kind of new disc brake device structural design scheme, to solve the little problem of existing disc brakes braking force.
Technological scheme of the present invention:
Large braking force disc brake device, is characterized in that: comprise brake disc, wheel hub, screw, friction plate, piston, piston and brake calipers shell.Wherein: brake disc is fixed on wheel hub by screw; Friction plate rear portion and piston fix, and piston is contained in piston, and piston is fixed in brake calipers shell.
Described large braking force disc brake device, feature is brake disc is circular, and surface is provided with dovetail groove, and dovetail groove cross section height is 0.5cm-10cm; Two waist angles are 60 °-120 °; Length of going to the bottom is 4cm-20cm.
Described large braking force disc brake device, feature is friction plate cross section is trapezoidal, and trapezoidal height is 0.5cm-10cm; Two waist angles are 60 °-120 °; Length of going to the bottom is 4cm-20cm; Friction plate is laid in dovetail groove on the disc brake rotor, and friction plate top and brake disc dovetail groove distance from bottom are 0-5cm.
Described large braking force disc brake device, feature is that brake disc inner ring and wheel hub have corresponding concavo-convex place, and the high spot on brake disc matches with the recess on wheel hub, and the recess on brake disc matches with the high spot on wheel hub.
Beneficial effect of the present invention:
1, braking force is comparatively large, can be used for large vehicle;
2, similar to existing disc brakes agent structure, versatility is good.

Fig. 2 is detonation configuration figure of the present invention.
Fig. 3 is the erection drawing of brake disc and wheel hub in the present invention.
Fig. 4 is the cooperation figure of brake disc and friction plate in the present invention.
Fig. 5 is the erection drawing of friction plate in the present invention, piston, piston and brake calipers shell
Fig. 6 is the explosive view of friction plate in the present invention, piston, piston and brake calipers shell.
Embodiment
Large braking force disc brake device, as shown in Figure 2, comprises brake disc, wheel hub, screw, friction plate, piston, piston and brake calipers shell.Wherein: brake disc is fixed on wheel hub by screw; Friction plate rear portion and piston fix, and piston is contained in piston, and piston is fixed in brake calipers shell.This device and existing dish-style brake device main structural similarity, improve its versatility.
As shown in fig. 1, after large braking force disc brake device assembling, small volume.It is installed by the mounting hole on brake disc, identical, easy and simple to handle with existing disc brakes mounting type.
As shown in Figure 3, brake disc inner ring and wheel hub have corresponding concavo-convex place, and the high spot on brake disc matches with the recess on wheel hub, and the recess on brake disc matches with the high spot on wheel hub.This makes both fixing comparatively firm, and the power suffered by screw of both connections is less
As shown in Figure 4, brake disc is circular, and surface is provided with dovetail groove, and dovetail groove cross section height is 0.5cm-10cm; Two waist angles are 60 °-120 °; Length of going to the bottom is 4cm-20cm.Friction plate cross section is trapezoidal, and trapezoidal height is 0.5cm-10cm; Two waist angles are 60 °-120 °; Length of going to the bottom is 4cm-20cm; Friction plate is laid in dovetail groove on the disc brake rotor, and friction plate top and brake disc dovetail groove distance from bottom are 0-5cm.Both are when braking, and can produce the braking force larger than plane brake disc and friction plate.
As shown in Figure 5, brake calipers shell both sides secure two piston, and piston has been installed strip friction plate, and this makes the area of contact when braking larger, braking force distribution evenly.
As shown in Figure 6, piston is provided with piston oil-cylinder, when braking beginning, in oil cylinder, oil pressure raises, and promotes piston forward, makes Friction Disk Surface contact with the dovetail groove internal surface on brake disc and rub, reduce the rotating speed of brake disc, be with motor car wheel to reduce rotating speed with this.
