Abstract
The utility model discloses a whole-sealed multiple-disc wet-type brake with adjustable braking torque, which has a smaller replacing cost and is wide in application, and comprises a friction disc, a fixed disc and a brake spring. For adjusting the torque, the whole-sealed multiple-disc wet-type brake adopts the following three ways: firstly, an adjusting bearing cushion is arranged at the left side or the right side of the brake spring, or adjusting bearing cushions are arranged at two sides of the brake spring simultaneously; secondly, the adjusting bearing cushion is arranged at the left side or the right side of a combination of the friction disc and the fixed disc, or the adjusting bearing cushions are arranged at two sides of the combination of the friction disc and the fixed disc; and thirdly, the above two ways are combined. The brake spring, or the friction disc and the fixed disc is a common spare part of the brake, and the types of the adjusting bearing cushion are same and can be adopted as the common spare parts, so that the material cost and the processing cost of the brake are greatly lower than that of a transparent cover.
Description
Technical field
The utility model relates to the adjustable enclosed multi-disc wet type parking brake of a kind of braking moment.
Background technique
Existing engineering vehicle uses shoe type or caliper disc brake mostly, and these two kinds of breaks are installed in the outside of gearbox, therefore receives the pollution of water, oil, mud etc. easily, makes misfunctioning of brake, brings potential safety hazard.Owing to be dry friction between braking plate and brake disc, the brake drum, the braking plate friction area is little in addition, and frictional force is big, makes that the life-span of braking plate is very low, needs often replacing.Shortcoming such as in addition, these two kinds of breaks exist also that volume is big, operating mechanism is complicated, steering force is big, stability in use and poor reliability, electromechanical integration degree are low.
The enclosed multi-disc wet type break more and more receives the favor of engineering vehicle, because the arrestment mechanism of enclosed multi-disc wet type break all is enclosed in the braking housing, does not receive the influence of water, oil, mud; Its friction plate and fixed tray are in the seal space that oil is housed, and frictional force is little; How right friction plate and fixed tray generally have in addition, and the suffered frictional force of single friction plate is very little, and the friction plate life-span is longer.But existing enclosed multi-disc wet type brake braking force square all is certain, can not with its change to need be littler or other vehicle of bigger braking moment on, compatible not so good.
U.S. DANA company once designed the adjustable enclosed multi-disc wet type Service Brake of a kind of braking moment, and it regulates braking moment through the lid that passes through that replacing is wrapped on fixed tray and the friction disk.If promptly want to increase braking moment, just change long the passing through of an axial dimension and cover, increase several again to friction disk and fixed tray more; If want to reduce braking moment, just change short the passing through of an axial dimension and cover, reduce several again to friction disk and fixed tray.Defective is following: braking moment of the every adjusting of this break just needs to change one and passes through lid, needs to prepare the lid that passes through of a plurality of different sizes, and cost of material, the processing cost of passing through lid are all very high.
The model utility content
The purpose of the utility model provides the adjustable enclosed multi-disc wet type break of less, the widely used braking moment of a kind of renewal cost.
The utility model comprises brake spring, friction disk and fixed tray; The adjustment support pads is installed in left side, right side or the both sides of said brake spring simultaneously or the adjustment support pads is installed simultaneously in left side, right side or the both sides of said friction disk and fixed tray combination; Left side, right side or the both sides of perhaps the combination of adjustment support pads and said friction disk and fixed tray being installed simultaneously in left side, right side or the both sides of said brake spring are simultaneously installed the adjustment support pads simultaneously, are used to adjust braking moment.
The advantage of the utility model is:
When 1, adjusting moment, a kind of mode is only to need to increase or reduce some braking belleville springs, reduces or increase adjustment support pads; Another kind of mode is only to need to increase or reduce somely to friction disk and fixed tray, reduces or increase the adjustment support pads; The third is comprehensive dual mode noted earlier.Braking belleville spring or friction disk, fixed tray all are the spare part in common of break, and the model of adjustment support pads all is the same, also can be used as spare part in common, and it is all much lower that its cost of material, processing charges pass through lid relatively;
2, be widely used, flexible for installation.Not only can be used for the underground mining vehicle, and can be applicable to open-air work machinery, or can adopt aforesaid way to adjust moment with the break of the utility model equivalent structure;
3, working life long more than the break that uses now, the break of use is approximately 150～2000 hours working life now, can reach 10000 hours the working life of New Brake;
4, need not safeguard.

Embodiment
As shown in Figure 1; The utility model mainly comprise brake axle 4 and be enclosed within successively vertically right baffle-plate 41, first on the brake axle 4 cover thoroughly 42, second cover 43 thoroughly, bearing the 44, the 3rd covers the 45, the 4th thoroughly and covers 46 and right baffle plate 47 thoroughly, right baffle-plate 41 and right baffle plate 47 are separately fixed at first and cover 42 left side and the 4th thoroughly and cover 46 right side thoroughly, first covers the 42 and the 4th thoroughly covers 46 thoroughly and is separately fixed at second and covers 43 left side and the 3rd thoroughly and cover thoroughly on 45 the right side; Second cover thoroughly the 43 and the 3rd cover thoroughly 45 be separately fixed at bearing 24 left side and right side; Second covers thoroughly in 43 and the 3rd covers thoroughly left bearings 48 and right bearings 49 are installed in 45, and left bearing 48 and right bearing 49 and brake axle 4 interference fit are equipped with piston 5, friction disk 2 and fixed tray 3 in the bearing 44; Piston 5 is the ladder annular; The big ring and second of piston 5 covers mounting spring group 2 in 43 thoroughly, and cluster spring 3 can be done axial motion along brake axle 4, and the little ring and the 3rd that fixed tray 2 and friction disk 3 are clipped in piston 5 covers between 45 thoroughly; Be interlaced arranged; The external splines of fixed tray 2 connects with the internal spline of bearing 4, axially moves along bearing 2 only, and the internal spline of friction disk 3 is connected with the external splines of brake axle 4; Both can rotate, also can axially move along brake axle 4 with brake axle 4.Have a hydraulic fluid port 441 on the bearing 44, when pressure oil when hydraulic fluid port 441 flows to piston, piston 5 left lateral compression butterfly spring, fixed tray 2 is thrown off with friction disk 3 simultaneously, power is delivered to downstream through brake axle 4.When pressure oil flows back to fuel tank, or hydraulic system breaks down, and piston 5 is right lateral under the effect of butterfly spring, compresses fixed tray 2 and friction disk 3, because the effect of friction torque makes vehicle slack.
As shown in Figure 1, adjustment support pads 11 is equipped with in the left side of brake spring 1 belleville spring group, when needs increase the braking moment of break, pulls down second and covers 3 thoroughly, takes out adjustment support pads 11, increases some belleville springs; When needs reduce the braking moment of break, pull down second and cover 43 thoroughly, take out some belleville springs, increase adjustment support pads 11.Perhaps adjustment support pads 23 is installed, when needs increase the braking moment of break, is pulled down the 3rd and cover 45 thoroughly, take out adjustment support pads 23, increase some fixed tray 2 and friction disk 3 on the fixed tray 2 and the right side of friction disk 3 combinations; When needs reduce the braking moment of break, pull down the 3rd and cover 45 thoroughly, take out somely to fixed tray 2 and friction disk 3, increase adjustment support pads 23.
