The technical solution of the utility model is: the 4 wheel driven farm tractor front axle, comprise the propons body, it is characterized in that: the propons body is provided with the power input and connects dish, and the power input connects dish and is connected with the angle gear wheel shaft, drive the angle gear wheel shaft and rotate, be arranged on angle gear and bevel gear engagement on the gear wheel shaft of angle; Bevel gear is connected with the right side major semiaxis with the left side major semiaxis respectively by diff, drives its rotation respectively or simultaneously; The left side major semiaxis is connected with the left side semi-minor axis by the left side universal coupling, is arranged on left side output pinion and the left side output big gear wheel engagement that is arranged on the output shaft of left side on the semi-minor axis of left side, drives its rotation; The left side output shaft is connected with left side output wheel disc;
The right side major semiaxis is connected with the right side semi-minor axis by the right side universal coupling, is arranged on right side output pinion and the right side output big gear wheel engagement that is arranged on the output shaft of right side on the semi-minor axis of right side, drives its rotation; The right side output shaft is connected with right side output wheel disc.
Further feature is: the left side inner oil seal is set on the major semiaxis of left side, the right side inner oil seal is set on the major semiaxis of right side.
4 wheel driven farm tractor front axle of the present utility model has following characteristics:
1, by being connected, makes the propons of trac. have power, power is transferred to two front-wheels of trac. through propons, make two front-wheels of trac. have onward impulse, eliminate the trac. deficiency that front-wheel skids easily in advancing with existing Transmission Bridge.
2, because two front-wheels have power, corresponding raising trac. has alleviated the degree of jolting in travelling in the adaptive ability of potted road surface walking.
3, adopt built-in oil enveloping structure axle case assy,, can prevent the oil leak in the main reduction gear by the sealing function of left side inner oil seal and right side inner oil seal.
4, the motor tricycle rear-end gear reduction assembly after employing improves has alleviated weight as the propons main reduction gear, has reduced manufacturing cost, has increased part universality, has reduced user's operation and maintenance cost.
5, adopt enhancement mode integrated output drop-gear box structure design and fit, strengthen its intensity, general assembly and easy to maintenance.
