Problems solved by technology

[0003] During use, due to the full floating design of the drum brake, the gap between the friction plate and the inner hole of the brake drum is changing all the time. The manufacturing accuracy of the inner hole of the brake drum and the wear of the friction plate cannot maintain the gap. If the gap is too large, the brakes will be weak, and if the gap is too small, it will be easy to lock or walk with the brake; and it is difficult to adjust the gap between the two. Become a bottleneck problem restricting the development of forklifts

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] refer to figure 1 , figure 2 , image 3 and Figure 4 In this embodiment, a forklift drive axle equipped with disc brakes includes a forklift axle housing 9 and a half shaft 10 crossing the forklift axle housing 9, and brake discs are installed at both ends of the forklift axle housing 9 from the inside to the outside. 11 and the wheel hub 12, the forklift axle housing 9 is equipped with a disc brake 13 corresponding to the brake disc 11. The disc brake 13 includes a caliper body 1, a driving mechanism arranged in the caliper body 1, and an inner wheel driven by the driving mechanism. The friction plate 2 and the outer friction plate 3 fixedly arranged on the caliper body 1 and opposite to the inner friction plate 2 , and the brake disc 11 is arranged between the inner friction plate 2 and the active surface of the outer fr...

Abstract

The invention discloses a forklift drive axle with disc brakes. The forklift drive axle comprises a forklift axle shell and a half shaft transversely penetrating the forklift axle shell. The two ends of the forklift axle shell are each provided with a brake disc and a hub sequentially from inside to outside, and the disc brakes corresponding to the brake discs are mounted on the forklift axle shell. According to the forklift drive axle, the disc brakes applied to a large-type vehicle drive axle are used as the brake discs with the braking effect, and therefore the problem that in a drum type brake device, due to wearing of friction pieces, the gaps between the friction pieces and the brake discs become large is solved, and the aim of improving the brake performance of a forklift is achieved.

Description

technical field [0001] The invention relates to the manufacturing field of forklift driving axles in construction machinery, in particular to a forklift driving axle equipped with disc brakes. Background technique [0002] The existing forklift driving axle adopts a drum brake as its brake. The drum brake includes a pair of brake shoes arranged on the inner side of the brake drum surface opposite to each other. The brake shoes are installed by bonding, riveting or screw connection. There is a friction plate, one end of the brake shoe is hinged on the brake bottom plate through a support pin, the brake shoe can rotate around the support pin, and the other end of the brake shoe is provided with a driving device, which can be a commonly used wheel cylinder piston When in use, the driving device will apply force to one end of the brake shoe, so that the other end of the brake shoe will rotate around the support pin, and the other ends of the brake shoe will lean against each oth...
