Wheel tractor transmission remote control mechanism

Abstract

The invention relates to a roller tractor speed changing box remote-operating mechanism. The roller tractor speed changing box remote-operating mechanism comprises at least two shifting fork shafts and shifting forks connected to the corresponding shifting fork shafts; the ends of the shifting fork shafts are connected with corresponding gear-shifting shifting blocks and used for shifting gear-shifting shifting heads of the gear-shifting shifting blocks to the inside of the gear-shifting shifting blocks; the gear-shifting shifting heads are connected to the far ends of gear-shifting shafts; speed changing connecting parts are disposed at the near ends of the gear-shifting shafts; the gear-shifting shafts are transversely disposed between the shifting fork shafts and gear-shifting connecting shafts; the far ends of the gear-shifting connecting shafts are connected with gear-shifting rocker arms, and the near ends of the gear-shifting connecting shafts are connected with front connecting rods; each gear-shifting rocker arm is connected with one end of the corresponding speed changing connecting part and controls the gear-shifting shafts to act; spherical hinge parts with spherical surfaces are disposed in the middles of the gear-shifting connecting shafts which can perform axial movement along mounting holes of the spherical hinge parts; spherical hinge seats with spherical holes are connected with the spherical hinge parts; the gear-shifting connecting shafts swing relative to the spherical hinge seats; the bottoms of gear-shifting rods are connected to the front ends of the front connecting rods. The roller tractor speed changing box remote-operating mechanism is simple and reasonable in structure, convenient to mount and capable of operating a gear-shifting module at the far end.

Description

technical field [0001] The invention relates to a remote control mechanism of a wheeled tractor gearbox, belonging to the technical field of wheeled tractor gearboxes. Background technique [0002] For large and medium-sized wheeled tractors, in order to meet the functions of various field operations and road transportation, the transmission ratio of the tractor is required to vary widely, and the variation of the tractor's transmission ratio is controlled by the transmission. At present, the gearshift mechanism of tractors is mainly composed of a shift lever, a shift knob, a shift fork shaft and a shift fork. The shift block on the shaft realizes the shifting of gears. With the continuous increase of the belt ratio of the transmission, due to the limitation of the internal space of the transmission, the shift mechanism cannot directly arrange the shift lever near the shift module, so that the control at a relatively long distance cannot be realized.

Problems solved by technology

With the continuous increase of the belt ratio of the transmission, due to the limited space inside the transmission, the shift mechanism cannot directly arrange the shift lever near the shift module, so it is impossible to achieve relatively long-distance control.
