Description
Technical field
The utility model belongs to tractor transmission case technical field, relates to the rear transmission case of a kind of east wind 12 hand tractors and variant motor truck thereof.
Background technique
In prior art, the gear box bottom of east wind 12 hand tractors and variant motor truck thereof is provided with a driving front case, and the effect of driving front case is to drive front-wheel to rotate.Along with the development of technology, east wind 12 hand tractors and variant motor truck thereof need to, to the future development of four-wheel drive, be realized the object of this type of tractor four-wheel drive, need to solve the problem to its trailing wheel transferring power.At present, on some large-scale tractors, realized four-wheel drive, but due to the particularity of east wind 12 hand tractors and variant motor truck gearbox designs thereof, after existing tractor, transmission case technology can not be applied in this type of tractor.
Summary of the invention
The utility model is in prior art, east wind 12 hand tractors and variant motor truck thereof lack rear transmission case technology, can not realize the problem of four-wheel drive, transmission case after a kind of tractor is provided, in the casing of this transmission case, main shaft is installed, on main shaft, be processed with spline, bearing for spindle is arranged on the two side of casing, casing is arranged on the rear end of gear box of tractor, on its main shaft, clutch cover is installed, bevel gear and power input component, on clutch cover, be processed with groove, the driving lever of conical tooth shaft and clutch cover is installed at casing rear portion, conical tooth shaft is movably arranged in axle bed, the cone fluted disc of conical tooth shaft front end stretches in casing and engages with bevel gear, driving lever is arranged in fixed base, the round end of its front end stretches in the groove of clutch cover in casing.
Adopt technique scheme, transmission case after the power of exporting on gear box of tractor can being introduced by power input component, band dynamic bevel gear, by being connected or disconnection of clutch sleeve control power input component and bevel gear, drive conical tooth shaft by bevel gear, conical tooth shaft rear wheel drive system drives trailing wheel to rotate, and realizes the four-wheel drive of tractor.
Technique scheme has two preferred versions, one is that power input component is designed to an input gear, be arranged between clutch cover and bevel gear, clutch cover is connected with main spindle multiple spline with bevel gear, input gear one side assembling jump ring, opposite side dress spacer, between input gear and main shaft, sliding sleeve is installed, in clutch cover one side design plush copper, at input gear one side design recess, recess is connected with plush copper hock.In this programme, when the transmission of power of gearbox is on input gear time, owing to sliding sleeve being installed between input gear and main shaft, input gear dallies on the sliding sleeve of main shaft, when driving lever is stirred clutch cover, when plush copper on clutch cover is inserted the recess of input gear one side, input gear drives clutch cover to rotate, and clutch cover drives main shaft to rotate, and main shaft band dynamic bevel gear rotates, bevel gear drives conical tooth shaft to rotate, and conical tooth shaft drives the rear wheel drive system work of tractor.
Another preferred version is that power input component is designed to sprocket wheel, the spindle nose of main shaft stretches out outside casing, sprocket wheel is arranged on the spindle nose of main shaft, bevel gear is arranged on clutch cover side, and both sides are fixed with jump ring, is designed with plush copper in clutch cover one side, be designed with recess in bevel gear one side, recess is connected with plush copper hock, and clutch cover is connected with main spindle multiple spline, between bevel gear and main shaft, sliding sleeve is installed.Adopt this programme, the power of gearbox transmission can be delivered on main shaft by sprocket wheel, drives main shaft to rotate, because clutch cover is connected with main spindle multiple spline, clutch cover rotates with main shaft, owing to sliding sleeve being installed between bevel gear and main shaft, main shaft dallies in the sliding sleeve of bevel gear, when driving lever is stirred clutch cover, when the plush copper of clutch cover one side is inserted the recess of bevel gear one side, clutch cover band dynamic bevel gear rotates, and bevel gear drives conical tooth shaft to rotate, and conical tooth shaft drives the rear wheel drive system work of tractor.
