Online detection bench for gearbox and detection method

Abstract

The invention discloses an online detection bench for a gearbox and a detection method. At present, the traditional automobile gearbox detection load side is mostly energy-consuming load, and energy recycling cannot be achieved. The online detection bench for the gearbox comprises a touch screen (1); the touch screen is connected with a programmable logic controller PLC (2) and an RS232/CAN communication converter (21) through Ethernet and an RS232 serial port line respectively; the PLC is respectively connected with a water cooling system (3) and an oil cooling system (4) through a control line; the oil cooling system is connected with the gearbox (10) through an oil cooling circuit; the water cooling system is connected with a load motor controller II (5) and a load motor II (8) respectively through a water cooling circuit; the load motor controller II is connected with a DC power supply (13) through a bus; and the DC power supply is connected with a driving motor controller (17) anda load motor controller I (16) through a bus. Thus, the online detection bench for the gearbox is disclosed.

Description

Technical field: [0001] The invention relates to an on-line detection test bench and a detection method of a gearbox. Background technique: [0002] Automobile gearbox is one of the main components of automobile transmission system. It is a transmission device used to coordinate the engine speed and the actual driving speed of the wheels. Its performance directly affects the safety and fuel economy of the car. As a gear device for transmitting power, the gearbox plays an important role in mechanical transmission; due to the complex mechanical structure of the gearbox itself, high degree of automation, and harsh working environment, the gearbox is easily affected by conditions such as temperature, humidity, and vibration. , Even a new gearbox may fail due to assembly and processing errors; at present, most of the traditional automotive gearbox detection loads are energy-consuming loads, which cannot realize energy recycling. [0003] There are two types of tests on gearboxes...
