Problems solved by technology
The problem in the above assembly process is: the brake housing 9 (with internal splines inside) and the partition plate 13 (the shape of the outer circle is external splines) transmit torque through splines
Therefore, when assembling the rotating brake housing 9, the outermost partition 13 tends to shift in position during the rotation process, causing the brake housing 9 to press against the partition and cannot be pressed onto the mounting surface.
Makes assembly difficult, making repair assembly even more difficult when maintaining the brake at a later stage

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 [0001] The invention belongs to the technical field of braking of loaders, in particular to the parking brake of wheel loaders. Background technique [0002] The existing wet parking brake for wheel loaders includes a brake housing 9, more than one partition 13 and more than one friction plate 11, see Figure 5 . When assembling the brake, first place more than one partition plate 13 and more than one friction plate 11 on the installation plane one by one and at intervals, and place the end plate 10 on the top; then assemble the O-ring 12 to the brake housing 9; then the brake housing 9 is set on more than one partition plate 13 and more than one friction plate 11 that have been stacked. The problem existing in the above assembly process is: the brake housing 9 (with internal splines inside) and the partition plate 13 (the shape of the outer circle is external splines) transmit torque through splines. In order to align the splines of these two parts during ...
