Abstract

The invention discloses a forklift travelling and parking integrated wet-type brake driving axle which comprises a main reducer assembly, an axle housing assembly, a left brake assembly, a right brake assembly, a left half axle, a right half axle, spline sleeves and fixing gear rings. A group of friction plates are arranged on each spline sleeve; a group of diaphragms are arranged in a groove of an inner hole of the left axle housing and a group of diaphragms are arranged in a groove of an inner hole of the right axle housing in the axle housing assembly; the friction plates and the diaphragms are alternately mounted; the left brake assembly and the right brake assembly are each provided with a parking brake mechanism and a travelling brake mechanism; hydraulic oil is guided into the left axle housing, and thus travelling brake and parking brake is completed in the parking brake mechanism and the travelling brake mechanism correspondingly under the action of the hydraulic oil. The friction plates are separated from the diaphragms through centrifugal force and inertia force after a vehicle moves. The influence on the parking brake from external factors like mud, water and oil is avoided, and the maintenance is convenient since the friction plates and the diaphragms can be maintained and replaced without disassembling an axle assembly.

Description

technical field [0001] The invention relates to forklift design technology, in particular, it relates to a forklift driving and parking integrated wet brake driving axle. Background technique [0002] Forklift drive axles mostly use drum brakes. Drum brakes have a simple structure and low cost, but the brake shoe friction plate is easy to crack and ablate, and it is difficult to remove the mud, water, oil, etc. on the brakes, which affects the braking performance. Stability, and there are shortcomings such as small braking area, unstable braking force, and poor heat dissipation. [0003] The fully enclosed wet brake can prevent the intrusion of mud and other substances, and the braking performance is stable. It adopts a single brake piston propulsion structure, and the friction couple is evenly stressed. The gap does not need to be adjusted and slipping is allowed to transmit torque. The multi-plate structure has good braking performance and prolongs the service life of the...
