Abstract

The automatic gear shifting and lubricating device for wheel and axle loading test table includes a task management unit, a lubricating and gear shifting management unit, a lubricating and cooling system, a pneumatic gear shifting mechanism, a gear box, a pressure sensor and stroke switches. It features the task management unit including microcomputer for running program and RS485 communication card for transmitting the operation command to the lubricating and gear shifting management unit, the lubricating and gear shifting management unit with program running PLC programmable controller to receive and process the operation command and to drive the lubricant oil pump, the cooling fan and the pneumatic solenoid valve, and the pressure sensor set in the lubricating and cooling oil path and stroke switches set on the cylinder to detect signal and feed back the signal to the task management unit. The present invention realizes the automatic control and remote operation in high efficiency and safety.

Description

(1) Technical field [0001] The invention relates to a gearbox and a lubricating device thereof. (2) Background technology [0002] For the large rotating load test bench, in order to meet the full power loading requirements, the real working conditions are simulated. A multi-gear gearbox should be used for torque and speed conversion. [0003] There are two ways of shifting gears: manual and automatic. Manual shifting is a traditional operation method, which requires the operator to operate in front of the gearbox in the test site, which is cumbersome and inefficient; the operator of automatic shifting does not need to go to the gearbox Recently, it can be operated remotely in the control room, which is simple and quick, and has high work efficiency. Automatic shifting is the development trend of multi-gear transmission design. [0004] Several schemes of pneumatic transmission, hydraulic transmission and electric transmission can be used for automatic gear shifting. In c...
