Improved forklift drive axle test board and testing method thereof

Abstract

The invention belongs to the technical field of engineering machinery and industrial vehicles, and particularly relates to a forklift drive axle test device. The improved forklift drive axle test board comprises a test board body. A drive axle mounting table is arranged on the test board body, load loading devices are arranged at the two ends of the mounting table and are magnetic powder loaders, a brake is arranged in the test board body, an oil cylinder is connected to the brake, and a braking device is connected to the oil cylinder. A drive axle to be tested is loaded with loads through the magnetic powder loaders, noise conditions and differential conditions caused when the drive axle works after the drive axle is arranged on a forklift are simulated, the braking device connected to the oil cylinder can detect sealing performance of the forklift drive axle when the forklift drive axle works, therefore, all produced forklift drive axles can be qualified, and defective products can be prevented from leaving a factory or being sold.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery and industrial vehicles, in particular to a test device for a drive axle of a forklift. Background technique [0002] The performance of the forklift driving axle should be tested before leaving the factory to confirm the quality of assembly, the meshing condition of each gear, the sealing of the driving axle, the braking and differential performance of the driving axle, and whether there is any abnormal sound and noise when the driving axle is running. Under no-load conditions, the traditional running-in test device is to drive the flange of the main reducer through the motor to achieve forward or reverse rotation. During the rotation process, the operator checks for leakage, abnormal sound and noise, etc. The transmission efficiency, braking and differential functions cannot be tested. Due to no-load running-in, the noise value of the drive axle after loading is quite different fro...

Problems solved by technology

[0002] The performance of the forklift driving axle should be tested before leaving the factory to confirm the quality of assembly, the meshing condition of each gear, the sealing of the driving axle, the braking and differential performance of the driving axle, and whether there is any abnormal sound and noise when the driving axle is running. Under no-load conditions, the traditional running-in test device is to drive the flange of the main reducer through the motor to achieve forward or reverse rotation. During the rotation process, the operator checks for leakage, abnormal sound and noise, etc. The transmission efficiency, braking and differential functions cannot be tested. Due to no-load running-in, the noise value of the drive axle after loading is quite different from the detected value during no-load running-in, and the performance of the whole vehicle cannot be guaranteed.
