Embodiment

[0031] See figure 1 , a fatigue test device for a parking brake of a forklift, comprising a brake fixing mechanism and a cylinder mechanism;

[0032] The brake fixing mechanism includes a fixed base plate 11, a brake mounting plate 12 and a hub mounting plate 13, and the brake mounting plate 12 and the hub mounting plate 13 are arranged upright and parallel at intervals on the fixed base plate 11;

[0033] The cylinder mechanism includes a cylinder bottom plate 21 and a cylinder 22, and the cylinder 22 is horizontally fixed above the cylinder bottom plate 21 through a pair of L-shaped support plates 23;

[0034] One end of the cable 31 is fixedly connected to the protruding end of the piston rod through the connecting seat, and a section of the cable corresponding to the cylinder bottom plate 21 is horizontally arranged above the cylinder bottom plate 21 through the support plate 24, and arranged coaxially with the piston rod;

[0035] The parking brake 32 and the wheel hub 3...

Abstract

The invention belongs to the technical field of parking brakes, and particularly relates to a fatigue test device of a parking brake for a forklift. The fatigue test device comprises a brake fixing mechanism and an air cylinder mechanism; the brake fixing mechanism is used for installing a parking brake and a hub; the air cylinder mechanism comprises an air cylinder bottom plate and an air cylinder; one end of an inhaul cable is fixedly connected with the extending end of a piston rod through a connecting base, and the section, corresponding to the air cylinder bottom plate, of the inhaul cable is horizontally arranged above the air cylinder bottom plate through a supporting plate and is coaxial with the piston rod. During a test, the piston is controlled to reciprocate to drive the inhaul cable head of the inhaul cable to reciprocate, and a fatigue test is carried out. Therefore, the hub is matched with the brake, the influence of the hub on the brake is reflected according to the actual situation, the brake fixing mechanism can fix the brake and the hub, and a whole vehicle does not need to be carried for testing; and the stress direction of the inhaul cable is kept consistent, the movement of the inhaul cable drives an internal mechanism of the parking brake to act, a fatigue test is achieved, and reliability verification of a product is completed.

Description

technical field [0001] The invention belongs to the technical field of parking brakes, in particular to a fatigue test device for parking brakes for forklifts. Background technique [0002] Forklift parking brake, as an important component, its performance is of great significance to the safety of forklift use. At present, in the forklift industry, the brake performance test can be carried out according to international, domestic, industry or internal standards of the enterprise. Such as GB / T 18849-2011 / ISO 6292:2008 "Brake Performance and Part Strength of Motorized Industrial Vehicles", JB / T13695-2019 "Brakes of Industrial Vehicles", etc., but most of these standards carry the whole vehicle for brake test, such as parking brake Dynamic performance, etc., but the fatigue durability test of the parking brake for forklifts is rarely involved. [0003] According to the operating standard, after the forklift is parked, its parking brake must be activated to ensure that the for...
