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 driving axle equipped with disc brakes, which comprises a forklift axle housing and a half shaft crossing the forklift axle housing. Brake discs and wheel hubs are installed on both ends of the forklift axle housing in sequence from the inside to the outside. Disc brakes corresponding to the brake discs are installed on the axle housing. In the drive axle of the forklift truck of the present invention, since the brake disc used for parking is the disc brake applied on the drive axle of a large car body, the gap between the friction plate and the brake disc caused by the wear of the friction plate in the drum brake can be eliminated. In order to achieve the purpose of improving the braking performance of the forklift.

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...
