The utility model content
To the above-mentioned deficiency that exists in the prior art, the utility model provides a kind of small-sized hand-held type agricultural machinery steering hardware, and this steering hardware has advantage simple in structure, laborsaving, that turn radius is little.
To achieve these goals, the technical scheme of the utility model employing is following:
A kind of small-sized hand-held type agricultural machinery steering hardware; Comprise change speed gear box, output semiaxis a, output semiaxis b and be installed in input sprocket and the diff in the change speed gear box; The end of output semiaxis a puts in the change speed gear box and passes the differential left housing, and said side gears a is enclosed within on the output semiaxis a through spline fitted; The end of said output semiaxis b puts in the change speed gear box and passes the differential right casing body; Said side gears b is enclosed within on the output semiaxis b through spline fitted, and it is external that the wheel toothed portion of input sprocket and differential right casing body by integral forming and input sprocket stretches out differential right casing; Input sprocket is connected with the driving gear of the drive power source of change speed gear box through chain, and the other end of output semiaxis a, output semiaxis b lays respectively at outside the change speed gear box.
As a kind of preferred version of the utility model, said output semiaxis a and output semiaxis b pass through bearing installation on gear box casing.
As another preferred version of the utility model, said differential left housing and differential right casing body pass through bolted connection.
Compare prior art, the utlity model has following beneficial effect:
The utility model is applied to automobile in the small-sized hand-held type agricultural machinery steering hardware with diff; Respectively two axle side gears are fixed on the output semiaxis; Reach the differential output of power through axle side gear and planetary engagement, be fixed on two left and right wheel or rotary blade groups realization differential steerings on the output semiaxis, structure, simple to operate thereby make; Just can realize that with have gentle hands light work handrail left and right wheel or rotary blade group turn to; Reach the labour-saving purpose, and owing to be the wheel or the rotary blade group differential steering on left and right both sides, turn radius is little.
