Embodiment Construction

[0017] see figure 1 , A wet brake for a forklift drive axle, including a left housing 6, a right housing 10, a piston assembly 5, staggered spacers 7 and friction plates 8. The left housing 6 is fixedly connected with the axle housing shaft head assembly 11 by bolts to form a rigid body, and the piston assembly 5, the spacers 7 and the friction plates 8 arranged in a staggered manner are installed in the space formed after the left housing 6 and the right housing 10 are connected. In the cavity, the friction plate 8 is connected with the hub assembly 12 through splines, and the spacer 7 is connected with the right housing 10 through splines.

[0018] Both sides of the friction plate 8 are evenly distributed with a first arc-shaped oil groove 3 in the clockwise direction and a second arc-shaped oil groove 4 in the counterclockwise direction, the first arc-shaped oil groove 3 and the second arc-shaped oil groove 4 interlaced to form a grid. The intersection of the first arc-s...

Abstract

The invention relates to a wet brake for a forklift drive axle, which comprises a left casing, a right casing, a piston assembly, as well as spacers and frication plates that are arranged in a stagger manner, wherein the piston assembly, as well as the spacers and the frication plates that are arranged in a stagger manner are mounted in a cavity formed by connecting the left casing with the right casing, first arc oil grooves in the clockwise direction and second arc oil grooves in the anti-clockwise direction are uniformly formed in the two side faces of the frication plates respectively, the first arc oil grooves and the second arc oil grooves are staggered with each other to form grids, a floating oil seal is arranged at the end part of the right casing corresponding to a hub, and another matched floating oil seal is mounted at the end part of the corresponding hub when in use. Oil flow channels of the arc oil grooves of the wet brake are longer, vortices are generated at cross points of the grooves, the oil discharging speed is relatively lower, the heat exchange time of the oil with a friction interface is slightly prolonged, and the utilization ratio of the cooling effect of the oil is increased.

Description

technical field [0001] The invention belongs to the technical field of forklift braking, in particular to a wet brake for a forklift driving axle. Background technique [0002] At present, most domestic forklift drive axle brakes use drum brakes, which are widely used because of their simple structure, consistent forward and reverse braking performance, low cost, and easy installation of parking brake mechanisms. In the front wheel braking of forklifts, however, due to the limitation of the size of the wheel hub, the drum brakes have the characteristics of small friction area and poor heat dissipation, which have seriously affected the modification, maintenance and safety of the whole vehicle; while forklifts mainly It is used in the occasion of transporting goods in a short distance, which makes the vehicle brake frequently, causing the brake friction plate to wear quickly, and at the same time, it is necessary to frequently adjust the brake drum clearance, and replace the ...
