External gearbox interlocking device

The external gearbox interlocking device comprises a transition base, an interlocking sliding block and pressing plates, the transition base is of a concave shell structure, the two pressing plates are symmetrically installed on the two sides of the opening position of the transition base, sliding grooves are formed between the pressing plates and the transition base, and the interlocking sliding block is connected between the pressing plates and the transition base in a sliding mode. The external gearbox interlocking device is simple in structure, convenient to install, low in requirement for an installation window, capable of being optimized and modified in time according to needs, low in manufacturing cost and short in period. In the scheme of upgrading the MT gearbox into the AMT system, the method is not limited by different gear shifting windows of various gearboxes, the applicability of the electric gear shifting mechanism is improved, the feasibility of an upgrading and restructuring scheme is improve
