How the automatic transmission oil change device works

Abstract

The invention discloses an automatic gearbox oil-exchanging device. The device comprises a mechanism connecting part and a circuit control part, wherein the mechanism connecting part comprises a bridge-type valve block, two quick connectors, an electromagnetic valve, a used-oil flow meter, an oil outlet valve, a fresh-oil flow meter, a gear pump and a fresh-oil tank; the two quick connectors are connected with the two opposite ports of the bridge-type valve block respectively; one of the rest ports is connected with the electromagnetic valve while the other port of the rest ports of the bridge-type valve block is connected with the fresh-oil flow meter; the electromagnetic valve is provided with a first outlet; the first outlet is connected with the used-oil flow meter and the oil outlet valve in sequence; the fresh-oil flow meter, the gear pump and the fresh-oil tank are connected in sequence; the circuit control part comprises a control module, a signal processing module and a driving module; the signal processing module is connected with the used-oil flow meter, the fresh-oil flow meter and the control module respectively; the control module is connected with the driving module; the driving module is connected with the electromagnetic valve and the gear pump. By adopting the automatic gearbox oil-exchanging device provided by the invention, the equivalent exchanging of the oil in the automatic gearbox oil tank is realized, and moreover, the device is simple to operate.

Description

【Technical field】 [0001] The invention relates to an automatic gearbox oil changing device and a working method thereof, which are used for changing oil for an automatic gearbox. 【Background technique】 [0002] With the rapid growth of China's economy, the number of cars in China is increasing at a rate of tens of millions every year. At present, there are more and more cars with automatic transmission, and the automatic transmission oil needs to be replaced after the car travels 60,000 kilometers, otherwise it may cause automobile safety accidents. [0003] The release of old oil and the filling of new oil in the automatic transmission are generally realized in the following two ways: 1. Release the old oil by disassembling the transmission or its pipeline, and then add new oil manually after completion; 2. Automatic transmission Oil change equipment completed. When changing oil manually, old oil will remain in the automatic transmission and pipelines, resulting in incomp...

Problems solved by technology

When changing oil manually, old oil will remain in the automatic transmission and pipelines, resulting in incomplete oil change, and the operation is complicated; the existing automatic transmission oil change device is limited by its structure and corresponding working methods The oil change process is cumbersome. After the oil change is completed, the old oil in the equipment needs to be discharged out of the equipment, which delays time. Some cannot achieve the same amount of automatic transmission oil replacement. Sometimes the automatic transmission is caused by excessive or insufficient filling. damaged box
