Description

Technical Field

[0001] The utility model relates to the technical field of forklifts, in particular to a pneumatic tooling for brake running-in of forklifts. Background Art

[0002] In current life, after the forklift brake shoe is installed, the contact surface is not completely fitted, and there is a certain gap or unevenness. Therefore, within a period of time after the shoe is installed, it is necessary to run-in to better combine and improve the friction effect. At present, manual running-in has no precise braking force control, and the running-in process can only be done under the extreme running-in state. The shoe generally suffers from excessive wear, which affects the life of the vehicle brake shoe. After the running-in is completed, the vehicle brake shoe and wheel hub are still in a high temperature state, and there are still odorous substances emitted. The vehicle needs to be cooled, which prolongs the vehicle production cycle. The traditional method uses manual running-in;

[0003] 1. This method consumes a lot of energy and is subject to control power and braking force. Since the braking force cannot be accurately measured during the manual running-in process, the degree of running-in cannot be controlled. The only way is to manually step on the brake pedal to the bottom and give maximum power to achieve the ultimate running-in state.

[0004] Second, it is not friendly to the operator and the environment. The brake shoes are continuously run-in under the maximum braking force in the extreme running-in state, which makes the brake shoes heat up. Under high temperature conditions, the adhesive resin in the shoes will release foul-smelling substances. Utility Model Content
