Gear interlocking device of five-gear manual transmission

The invention relates to a gear interlocking device of a vehicle transmission and particularly relates to the gear interlocking device of a five-gear manual transmission. The device comprises three shifting fork shafts which are arranged on a transmission body in parallel and can move axially and three interlocking shifting levels which are arranged in a lamination mode along the axial line of the shifting fork shafts and can respectively rotate relative to the transmission body, wherein the three shifting fork shafts are arranged triangularly in space, when the interlocking shifting levels are located at the same side of the central connecting line of two adjacent shifting fork shafts and shifting fork shafts do not move in an axial direction, the interlocking shifting levels are inserted into grooves of the two adjacent shifting fork shafts with allowances; and when one of three shifting fork shafts moves in an axial direction, two interlocking shifting levels which are inserted into the grooves with allowances slide from the grooves and rotate relative to the transmission body, the two interlocking shifting levels are embedded in grooves of anther two shifting fork shafts with allowances, and the allowances are reduced. By the aid of the technical scheme, the reliable interlocking among gears of the transmission is achieved, and the spatial design of the transmission is easy.
