The utility model
EPS (electronic portable shifting system) is electronic-pneumatic system that mounted besides the main box of the transmission gearbox without changing the original transmission design. There is no mechanical connection between the gear shifting unit and the transmission, which was an independent system connected by a cable only. It helps to save the installation space without any special position requirements (The shift control cable can be arbitrary bended, connected between the unit and the transmission), which is perfectly adapted to the low chassis bus installation characteristics and long distance transmission control, simplifies the loading process.
The ECU controls the electromagnetic valve according to the operator's shifting requirements and the condition. Once the electromagnetic valve receiving signals from the ECU, the valve will actuate cylinder piston rod by open and close the valve core to compress air, then actuate the gear shifting mechanism motion, so that to achieve the purpose of shifting. The product also can be used to separate controlling in other industries.
