Common pump station for forklift torque converter and clutch testing

Abstract

The invention relates to a shared pump station for testing of a forklift torque converter and a clutch. The shared pump station is composed of two oil tanks, two motors, two oil pumps, two one-way valves, four check valves, an overflow valve, a control valve assembly and a pipeline. The shared pump station is provided with a torque converter detection port and a clutch detection port, and meets the requirements of performance test of the torque converter and the clutch. The shared pump station is adjustable within the high flow range from 8L / min to 10 L / min. For the tested torque converter, the oil supply amount can be adjusted continuously, and the maximum oil supply amount is about four times higher than the minimum oil supply amount. The first oil tank and the second oil tank can be used as different oil sources where a work pump of the pump station sucks oil; besides, an oil suction opening is provided with two passageways, so that oil is sucked from the different oil sources, and any one of the two oil passageways is opened or closed through the manual check valves.

Description

technical field [0001] The invention belongs to the technical field of performance testing of transmission parts, and in particular relates to a performance testing device of a torque converter or a clutch. Background technique [0002] Torque converters and clutches are key components of forklift gearboxes. They need to be tested frequently in the comprehensive performance test system of transmission parts. During the test, pump stations are required to simulate the hydraulic environment in which the gearbox operates. [0003] The performance test of the existing torque converter or the performance test of the clutch needs to be equipped with two different sets of pumping stations respectively, and the two sets of pumping stations must be equipped with components such as motors, pumps, valves, etc., and the equipment investment cost is high. [0004] There are many types of forklifts used in different working conditions, and there are many types of torque converters and clu...

[0003] The performance test of the existing torque converter or the performance test of the clutch needs to be equipped with two different sets of pumping stations respectively, and the two sets of pumping stations must be equipped with components such as motors, pumps, valves, etc., and the equipment investment cost is high

[0004] There are many types of forklifts used in different working conditions, and there are many types of torque converters and clutches that need to be tested for performance; the corresponding performance parameters are different, so pump stations with different specifications need to be equipped. When the pump station needs to be replaced, the operation is troublesome
