Description

A kind of novel multi-disc brake

Technical field:

The utility model relates to mine vehicle technical field, is a kind of novel multi-disc brake specifically, is used to mate can satisfy driving and parking function requirement on the heavy vehicle bridge, and can realizes that brake clearance adjusts the multi-disc brake of function automatically.

Background technique:

Development along with the mine vehicle; The multi-disc brake required braking force of coupling is also increasing; At present, post gap increases the existing multi-disc brake that uses and contradiction has appearred in the braking response time because the friction pair abrasion causes, and causes the friction pair quantity limited; Can not effectively improve braking moment, and not have parking braking function.

Summary of the invention:

The purpose of the utility model is the deficiency that overcomes existing technology, and a kind of novel multi-disc brake is provided, and has mainly solved the problem of existing mine with the difficult coupling of vehicle large-tonnage, multiaxis (wheel), little wheel rim and break.

In order to achieve the above object, the utility model is achieved in that a kind of novel multi-disc brake, and it comprises shell and spline flange; Establish the installation base plate on the shell, its special way is that moving plate connects with the spline flange, and stator connects with shell; Moving plate and stator are spaced, and end face of guide finger is pressed on the shell, and another end face is pressed on the piston; Suit return spring on guide finger, outside piston relies on multi-thread self-locking thread to be connected with adjustment ring endoporus, and adjustment ring cylindrical has the spiral camber that several can not self-locking; Outer conical ring endoporus has the spiral camber that several can not self-locking; The adjustment ring becomes a pair of power screw secondary with outer conical ring, the two modulus is inconsistent, and drive gap is axially arranged; Shell and outside establish the adjustment spring between the conical ring, the conical surface of outer conical ring and interior conical ring matees each other, interior conical ring is fixed on the shell; On shell, establish the Parking push-plate; The Parking push-plate is pressed on the adjustment ring with the driving push-plate, and driving push-plate and interior conical ring endoporus form the service brake chamber, and by the driving oil sealing sealing; The Parking push-plate becomes the parking braking chamber with interior conical ring outer ring; And, on the Parking push-plate, establish the Parking spring by the Parking oil sealing sealing, the other end of Parking spring is pressed on to be installed on the base plate.

A kind of novel multi-disc brake of the utility model, its described moving plate and stator are 12 groups.

The described a kind of novel multi-disc brake of the utility model compared with prior art has following good effect: 1, brake functionality is complete: break is also adjusted function automatically with parking braking and brake clearance and is integrated in the break except that all capable parking braking functions of general break; 2, polydisc structure braking moment is big, and helps modularization and seriation design; 3, parking braking relies on the Parking spring of dish to realize, braking force is big, it is little to take up room; 4, adjust brake clearance automatically: with the abrasives wearing and tearing, brake clearance is adjusted invariable automatically, guarantees brake safe, and abrasives obtains utilizing fully, has improved working life, has reduced the maintenance expense.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

The drawing explanation:

1 spline flange 2 is installed conical ring 15 driving 19 parking braking chambeies, push-plate 16 driving chamber oil sealing 17 Parking chamber oil sealings, 18 service brake chambeies in the base plate 3 shells 4 stators 5 moving plates 6 guide fingers 7 return springs 8 pistons 9 adjustment rings 10 Parking push-plates 11 Parking springs 12 adjustment springs 13 outer conical rings 14

Embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and specify the utility model.

Embodiment 1, referring to Fig. 1, is processed into spline flange 1 and shell 3, and base plate 2 is installed in fixed installation on the shell 3, and moving plate 5 is connected with spline flange 1, and stator 4 passes through splined with shell 3, and moving plate 5 is spaced with stator 4, is 12 groups; Suit return spring 7 on

guide finger

6,6 one end faces of guide finger are pressed on the shell 3, and another end face is pressed on the piston 8; Piston 8 cylindricals rely on multi-thread self-locking thread to be connected with adjustment ring 9 endoporus; Adjustment ring 9 cylindricals have the spiral camber that several can not self-locking, and outer conical ring 13 endoporus have the spiral camber that several can not self-locking, and adjustment ring 9 forms a pair of power screw pair with outer conical ring 13; The two modulus is inconsistent, and drive gap is axially arranged; Shell 3 and outside adjustment spring 12 is installed between the conical ring 13, through being bolted on the shell 3, adjustment spring 12 matees the conical surface of itself and interior conical ring 14 for outer conical ring 13 certain pressure each other with interior conical ring 14; Fixing Parking push-plate 10 on shell 3; Parking push-plate 10 is pressed on the adjustment ring 9 with driving push-plate 15, and driving push-plate 15 forms service brake chamber 18 with interior conical ring 14 endoporus, and by 16 sealings of driving oil sealing; Parking push-plate 10 forms parking braking chamber 19 with interior conical ring 14 cylindricals; And by 17 sealings of Parking oil sealing, Parking spring 11 1 ends are connected with Parking push-plate 10, and the other end is pressed on to be installed on the base plate 2; At last spline flange 1 and wheel hub are passed through Bolt Connection, base plate 2 is installed through being bolted on the axle housing.

The described a kind of novel multi-disc brake of the utility model; Working principle: 1, realize service brake: automobile high pressure oil in the process of moving is full of Parking chamber compression Parking spring always; When needing braking; Hydraulic oil injects the service brake oil pocket, and high pressure oil promotes driving push-plate 15, adjustment ring 9 and piston 8 and compresses and respectively organizes friction pair, thereby reaches the purpose of braking and resetted by return spring 7; This process has overcome adjustment ring 9 and outer conical ring 13 power screw countershafts to gap (being brake clearance), and the adjustment ring has only axial motion, and outer conical ring rotation is skidded, and regulating mechanism is not worked.2, realize the gap adjustment: when wearing and tearing having occurred; Exceeded adjustment ring 9 and outer conical ring 13 power screw countershafts when the setting value of gap (being brake clearance), braking process is with above-mentioned consistent, when resetting under the effect of return spring 7 outside conical ring 13 and interior conical ring 14 locked; Outer conical ring 13 transfixions; Adjustment ring 9 relative piston 8 under the power screw side effect outwards screws out, thereby the balance wearing clearance keeps setting the gap.3, realize parking braking: the high pressure oil that always is full of the Parking chamber when needing parking braking discharges, and removes compression Parking spring 11, and Parking spring 11 compresses Parking push-plate 10, adjustment ring 9 and piston 8 and compresses and respectively organize friction pair, thereby reaches the purpose of braking.
