Abstract
A caterpillar tractor speed change box assisting operation device comprises a double-acting air cylinder, a rocker arm, a sensor assembly, a double-flexible-shaft operation assembly and a main speed change upper cover installation assembly. A front-back gear shifting push-pull flexible shaft of the double-flexible-shaft assembly is connected with a piston rod of the sensor assembly, a left-right gear shift push-pull flexible shaft is connected with a transposition upper rocker arm of the main speed change upper cover installation assembly, and the double-acting air cylinder and the sensor assembly are connected at two ends of the rocker arm. Compared with a general speed change box operation structure, the device uses an air assisting method to enable gear shifting operation to be convenient and reliable. Due to the double-flexible-shaft mechanism, the distribution problem of the operation positions in a driving cab is solved. Thus, operation comfortableness is improved.
