A 200‑600kw gearbox automatic shift controller

Abstract

The invention provides an automatic gear shifting controller of a 200-600 KW transmission. The automatic gear shifting controller comprises a metal housing, a control board, an automobile connector, an automobile connector platelet and a harness. The metal housing is earthed, one side of the metal housing is provided with a notch, the metal housing comprises an upper shell and a lower shell, a conductive sealing strip is arranged between the upper shell and the lower shell, and the inner bottom surface of the lower shell is provided with a concave surface and a groove. Heat radiation fins are arranged in the concave surface, and heating fins are arranged in the groove. The control board is earthed and mounted in the lower shell of the metal housing and is connected with the automobile connector through pins in two rows. The automobile connector platelet is arranged at the notch of the metal housing, and the automobile connector is welded on the automobile connector platelet and forms a continuous closed conductive curved surface with the metal housing. By adopting the above technical scheme, normal working can be realized under high electromagnetic interference and low temperature, and environment adaptability of the transmission is improved.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a gear control device for a 200-600KW gearbox. Background technique [0002] In 1939, General Motors of the United States applied an automatic transmission device to a car for the first time. This device can automatically change the transmission ratio, thereby adjusting or changing the power output performance of the engine, and can better adapt to the needs of external loads and road conditions. Since 1981, some automobile companies in the United States and Japan have successively developed various microcomputer-controlled automatic transmission systems, such as electronically controlled hydraulic torque converter automatic transmissions, electronically controlled multi-stage gear transmissions, etc. Compared with the manual transmission device, the automatic transmission device can guarantee the best shifting schedule, good shifting accuracy, good fuel economy an...

AI Technical Summary

Problems solved by technology

[0003] At present, the R&D and application of electronically controlled automatic transmissions, especially high-power automatic transmissions from 200kw to 600kw, are not very mature in China. This type of controller is basically monopolized by foreign countries, especially in some special fields where technology is still blocked. In reality, in view of this situation, the present invention provides an automatic shift controller that meets the national military standard GJB151A-97 and can work in a low-temperature environment. The device is based on electronics, microprocessors and modern control theory. - 600KW hydraulic transmission as the carrier, automatic shift control with large trucks as the load, in order to meet the application under complex environmental conditions, EMC and low temperature characteristics are important components of the present invention
