Abstract
The invention relates to a fully sealed wet parking brake for a wheel type loading machine. A brake end cover is arranged at one axial side of a brake casing, a middle part between the brake end cover and the brake casing is provided with a piston, a separation plate and a friction sheet are sequentially arranged in a spline hole formed in the other axial side of the brake casing, a baffle ring groove is formed in the inner radial direction of a hole opening of the spline hole of the brake casing, an annular baffle ring is arranged in the baffle ring groove, an annular baffle plate is arranged in the axial direction between the baffle ring and the separation plate at the outermost end, the baffle plate is movably matched with the spline hole of the brake casing, and the circumference part of the axial outer end surface of the baffle plate is in contact with the axial inner end surface of the baffle ring. The fully sealed wet parking brake has the advantages that through the structural improvement on the wet type brake, the integral assembly of the wet brake can be realized, the mounting and the dismounting of the wet type brake on a whole vehicle are more convenient, the operation efficiency is greatly improved, the assembling time is reduced, and the work intensity of operators is reduced.
Description
Technical field
The invention belongs to the braking technology field of loader, be specifically related to the Parking Brake of wheel loader.
Background technique
The existing wet-type parking brake for wheel loader, comprises brake casing 9, dividing plate 13 more than a slice and friction plate more than a slice 11, sees Fig. 5.This break is in when assembling, first by dividing plate more than a slice 13 and friction plate more than a slice 11 by being placed on mounting plane of part, interval, place end plate 10 topmost; Then O type circle 12 is assembled in the groove of brake casing 9; Again brake casing 9 covers are installed on the dividing plate 13 more than a slice of piling up and friction plate more than a slice 11.The problem that above-mentioned assembly process exists is: there is internal spline brake casing 9(inside) be shaped as external splines with dividing plate 13(cylindrical) be by spline carry-over moment.When assembling, for these two-part are aimed at spline, need turning stopper housing 9; Simultaneously because O type circle 12(seals with attachment face sealing brake casing 9) for rubber parts, there is certain elasticity.Therefore in assembling is rotated when brake casing 9, the dividing plate 13 of outermost end easily occurs that in rotation process position moves, and causes brake casing 9 to be pressed onto on dividing plate, cannot be pressed in mounting surface.Make assembling difficulty, in the time of this break of later maintenance, when maintenance assembling, difficulty is larger.
Summary of the invention
In order to improve the efficiency of assembling of wet brake, facilitate the maintenance in later stage, reduce operator's labor intensity, the invention provides a kind of Wholly-enclosed wetting Parking Brake for wheel loader.
Concrete technical solution is as follows:
Wholly-enclosed wetting Parking Brake for wheel loader comprises brake casing 9, and an axial side of described brake casing 9 is provided with break end cap 1, and the middle part between break end cap 1 and brake casing 9 is provided with piston 4; In the splined hole of the axial opposite side of brake casing 9, be interval with successively dividing plate 13 and friction plate 11;
The aperture internal diameter of the splined hole of described brake casing 9 upwards offers circlip groove 14, is provided with the back-up ring 15 of ring-type in described circlip groove 14; The baffle plate that is axially arranged with ring-type 16 between described back-up ring 15 and the dividing plate 13 of outermost end, coordinates for moving between described baffle plate 16 and the splined hole of brake casing 9; The circumference place of the axial outer end face of described baffle plate 16 contacts with the axial inner ends face of back-up ring 15; Described back-up ring 15 is for being provided with the split washer of fracture; The axial outer end middle part of described baffle plate 16 is provided with the Step Shaft of evagination, and the end face of baffle plate 16 and the axial inner ends face of back-up ring 15 in Step Shaft outside contact.
Useful technique effect of the present invention embodies in the following areas:
1. the present invention is by the architecture advances to wet brake, realize the integrated type assembling of wet brake, made the installation of wet brake on car load, dismantle more conveniently, improved greatly operating efficiency, reduce installation time, reduced operator's labor intensity;
2. improved the maintainability of wet brake, especially on car load assembly space hour, its property easy to maintenance is more outstanding;
3. reduced the installation of wet brake on car load, to assembling attendant's technical ability requirement.

Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is back-up ring structural representation.
Fig. 4 is brake casing structural representation.
Fig. 5 is existing wet brake structural representation.
Sequence number in upper figure: break end cap 1, spring 2, pin 3, piston 4, bolt 5, brake casing 9, end plate 10, friction plate 11, O type circle 12, dividing plate 13, circlip groove 14, back-up ring 15, baffle plate 16.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention is further described.
Referring to Fig. 1, comprise brake casing 9, break end cap 1, spring 2, pin 3, piston 4, end plate 10, O type circle 12, five above friction plates 11 and six above dividing plates 13 for the Wholly-enclosed wetting Parking Brake of wheel loader.An axial side of brake casing 9 is installed with break end cap 1, and the middle part between break end cap 1 and brake casing 9 is provided with piston 4; In the splined hole of the axial opposite side of brake casing 9, interval is provided with dividing plate 13 and friction plate 11 successively; The aperture internal diameter of the splined hole of brake casing 9 upwards offers circlip groove 14, is provided with the back-up ring 15 of ring-type in described circlip groove 14, and back-up ring 15 is for being provided with the split washer of fracture.Referring to Fig. 2,3, the baffle plate that is axially arranged with ring-type 16 between described back-up ring 15 and the dividing plate 13 of outermost end, coordinates for moving between described baffle plate 16 and the splined hole of brake casing 9; The axial outer end middle part of baffle plate 16 is provided with the Step Shaft of evagination, and the end face of baffle plate 16 and the axial inner ends face of back-up ring 15 in Step Shaft outside contact.
Carrying out wet brake when assembling, first end plate 10, dividing plate 13, friction plate 11 are assemblied in brake casing 9, by two bolts 5 by Assembly of the parts such as break end cap 1, spring 2, pistons 4 on brake casing 9.Utilize baffle plate 16 that dividing plate 13 and brake casing 9 end faces are separated, and the outer side surface of baffle plate 16 have a Step Shaft, for the installation of back-up ring 15 provides space.Finally back-up ring 15 is assembled in the circlip groove 14 of brake casing 9, referring to Fig. 4.So just the assembling of wet brake itself will be completed.In the time that car load assembles, wet brake is assembled on car load as a single piece, has improved car load efficiency of assembling.Carrying out wet brake while safeguarding, can be by under wet brake integral demounting, after maintenance, entirety is installed again.
