MECHANISM FOR CONTROLLING GEAR BOX Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: mechanism has shifting lever interacting alternatively with shifting jaws of the first, second, third, fourth transmissions through intermediate lever arranged on parallel rods, and jaws of the fifth transmission and back movement, stop ring secured to one of the rods, and locking mechanism for fifth transmission. The intermediate lever is mounted for permitting alternative movement along the rod of the intermediate lever or the rod of the back movement jaw. The back movement jaw and stop ring are secured to the rod of the back movement jaw. The control mechanism is provided with carrier and mechanism for locking the back transmission. The carrier is secured to the rod of the intermediate lever and connected with the rod of the jaw of the fifth transmission. The rod is mounted for permitting axial movement together with the jaw of the fifth transmission. The locking mechanism of the back movement transmission is coincident with the mechanism for locking the fifth transmission. The mechanism for locking the fifth transmission and back movement is positioned inside the intermediate lever between the rod of the intermediate lever and rod of the back movement jaw. EFFECT: enhanced reliability. 5 dwg
