Abstract
The utility model discloses a shifting fork bar mechanism for a stepless speed change transmission case of large-power farm machinery, which is characterized in that: the shifting fork bar mechanism comprises a shifting fork bar, an operation clutch rod outer-welded part; one end of the shifting fork bar is provided with a rotating shaft segment which is used for pivoting with a housing, and the other end is fixedly connected with the operation clutch rod outer-welded part and is also provided with a rotating shaft segment which is used for pivoting with the housing; the central part of the shifting fork bar is provided with a segment of arc-shaped surface, which is matched with a channel section on a clutch gear; the operation clutch rod outer-welded part is composed of a sleeve; a projected arm for turning and a connection arm for braking are welded on the sleeve. Two ends of the arc-shaped surface are provided with bearings. Axes of the bearings are parallel with an axis of the shifting fork bar. The two bearings extend to the arc-shaped surface. The matching of the shifting fork bar in the channel section on the clutch gear through the arc-shaped surface and the bearings which are equipped at two ends can move flexibly. The shifting fork bar mechanism for the stepless speed change transmission case of the large-power farm machinery has the following advantages: simple structure, small friction and long service life.
Description
Technical field
The utility model relates to the agricultural machinery technical field, especially a kind of shifting fork bar mechanism that is used for high-power agricultural machinery equipment stepless change transmission case.
Background technique
At the bigger characteristics of China's south paddy field viscosity, the fraction horsepower diesel engine that present existing reaper is used is in the farming operation process, therefore this working environment needs the high-power mechanical actuation device, yet the phenomenon of detonation appears in the transmission case of existing high-power mechanical actuation device easily when bearing just frequently live load, simultaneously the gear wear in this process middle gear transmission case is too fast, influences the farmland operation precision, efficient is low and maintenance cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, finish turn to brake control be used for can bear high-power output, the shifting fork bar mechanism of the high-power agricultural machinery equipment transmission case of the frequency that the height that can stand to load changes.
Further purpose is to reduce friction, more flexibility and reliability finishes and turns to control.
The utility model solves the problems of the technologies described above the technological scheme that is adopted:
A kind of shifting fork bar mechanism that is used for high-power agricultural machinery equipment stepless change transmission case, it is characterized in that: this shifting fork bar mechanism comprises shifting fork bar, the outer seam of steering clutch shaft, one end of shifting fork bar is provided with the rotating shaft section that is used for the shell pivot joint, the outer seam of the other end and steering clutch shaft is fixedlyed connected and is provided with equally at this end and is used for the rotating shaft section that articulates with shell, be provided with one section arc shaped surface that cooperates with draw-in groove on the clutch gear at the middle part of shifting fork bar, the outer seam of steering clutch shaft is made of a sleeve, is welded with projection arm that is used to turn to and the link arm that brakes usefulness on sleeve.
The two ends of described arc shaped surface are equipped with bearing, the shaft axis of bearing and the axis parallel of shifting fork bar, and two bearings is stretched to arc shaped surface, and the cooperation in the draw-in groove on clutch gear can flexible motion by arc shaped surface and end mounted bearing for shifting fork bar.
The roller end of described two bearings is provided with adjusting nut.
The beneficial effects of the utility model are: have advantage simple in structure, as to rub little and long service life.
Wherein the middle part of shifting fork bar is provided with one section arc shaped surface that cooperates with draw-in groove on the clutch gear, the outer seam of steering clutch shaft is made of a sleeve, on sleeve, be welded with the link arm of the projection arm that is used to turn to and brake usefulness, on parts, just can realize the function that turns to and brake simultaneously like this by external relevant control power.
The utility model is owing to be provided with arc shaped surface and end mounted bearing on shifting fork bar, arc shaped surface is encircled the draw-in groove on the clutch gear, be connected for rolling between the two groove sidewalls of the draw-in groove on the two ends that end mounted bearing can make arc shaped surface and the clutch gear, so can make and to stir clutch gear in the draw-in groove of shifting fork bar on clutch gear flexibly and move along its axial direction, reach reduce the friction, more flexibility and reliability finish the requirement that turns to control.
