Description
Technical field
The utility model relates to a kind of driving device that makes the fuselage rising of four-wheeled tractor.
Background technology
In the prior art, four-wheeled tractor has front and rear wheel.Front-wheel has front axle assembly, front axle assembly has the pedestal beam of level, pedestal beam location is connected under the crossbeam of trac. vehicle body, the two ends of pedestal beam are connected with vertical vertical shaft, vertical shaft is a pipe, and deflecting bar is arranged in the pipe, and there is drag-link-arm the vertical shaft upper end, the vertical shaft lower end is connected with the front-wheel minor axis of level, on the front-wheel minor axis front vehicle wheel is arranged; There is crankcase at rear portion on the trac. crossbeam, the dynamic delivery orifice in crankcase both sides, the takeoff output hole is connected with the trailing wheel minor axis, be with on the trailing wheel minor axis with the trailing wheel minor axis concentric connect dish, there is the brake disc concentric with the trailing wheel minor axis outer end that connects dish, there is the spline axle head that can link to each other with crankcase takeoff output hole the inner end of trailing wheel minor axis, and there is the taper spindle nose that can link to each other with the axis hole of rear wheel the outer end of trailing wheel minor axis.On the outer end of trailing wheel minor axis rear wheel is arranged.This four-wheeled tractor is because the axle of rear wheel is directly to be connected on the takeoff output hole of crankcase, the vertical shaft of the front axle assembly of front vehicle wheel is very short, so the trac. longeron is very little apart from ground-surface height, the radius that only is equivalent to trailing wheel is long, for 12~20 horsepowers commonly used four-wheeled tractor of present rural area, at the bottom of the car overhead distance be 300~400 millimeters.This four-wheeled tractor is when the farm work walking in high bar crop growth mid-term, when spraying medicine, fertilising, intertillage mid-term, because crop is on the occasion of jointing, height can reach about 1 meter, cane is very crisp, the longeron of the trac. in the prior art is very little apart from ground-surface height, is easy to scrape disconnected crops.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of trac. fuselage rising driving device that the four-wheeled tractor fuselage is raise.
The utility model is realized with the following method.
Trac. fuselage rising driving device has the strip shape chain cover, the two ends of strip shape chain cover have parallel to each other on, following two axles, on, the length direction of following two axles and chain cover is perpendicular, on, following two interaxle distances are 500~1500 millimeters, on, following two axles are respectively from oppositely stretching out chain cover, on in the chain cover, following two between centers have driving device, last axle rotates and can drive the lower shaft rotation, last shaft extension goes out chain cover partly the spline axle head that can link to each other with crankcase takeoff output hole, lower shaft stretches out chain cover partly the taper spindle nose that can link to each other with the axis hole of rear wheel, the upward axle one side outer wall of the outer upper end of chain cover, have with last axle concentric connect dish, the lower shaft one side outer wall of chain cover outer lower end has the brake disc concentric with lower shaft.
The utility model can with increase front axle assembly and be used.The structure of increasing the front axle assembly in front axle assembly and the prior art is identical, and just the vertical shaft at the vertical shaft at the two ends of the pedestal beam two ends of setting a roof beam in place than prior art axis is long, and length is corresponding to be 500~1500 millimeters.
The utility model can be transformed the four-wheeled tractor in the prior art, and its fuselage is raise.During transformation, take off front axle assembly and the rear axle that links to each other with crankcase takeoff output hole on the existing four-wheeled tractor, be installed on the position of trac. front axle assembly increasing front axle assembly, spline axle head of the present utility model is linked to each other with trac. crankcase takeoff output hole, be connected on the crankcase connecing dish, the taper spindle nose links to each other with rear wheel.
The utility model and increase front axle assembly and be installed on the four-wheeled tractor after owing to increase the vertical shaft lengthening of front axle assembly, the driving device of rear wheel by the strip shape chain cover links to each other with bent axle takeoff output hole and increases, so can make the rising of trac. fuselage.The trac. that fuselage raises is suitable for when high stem crop is grown mid-term in field traveling operation very much.The trac. that fuselage raises also is easy to be reduced into original height.
Below in conjunction with accompanying drawing, the utility model is further described.
