Problems solved by technology
[0002] At present, existing vehicles, especially agricultural vehicles such as sprayers, use two-wheel or four-wheel steering. Two-wheel steering is not convenient for farmland operations due to its large steering radius. Too small a radius makes maneuvering difficult

The invention relates to a two-wheel steering and four-wheel steering switching mechanism for vehicles, which can easily implement two-wheel steering and four-wheel steering. The two-wheel steering and four-wheel steering switching mechanism comprises a driving rotary shaft, a driving rocker arm, a driving pin shaft, a driving rod, a driven rod, a driven pin shaft, a driving rocker arm and a driven rotary shaft which are sequentially connected, a fixed pin shaft is fixed on the driving rod and articulated with a clutch arm, and a control lever is articulated with the clutch arm. When the control lever is operated, the clutch arm is tensioned by the control lever, so that a round head of the clutch arm leaves a notch on the driven rod, and thereby only two driving steering wheels of a vehicle can turn; otherwise, the clutch arm is pressed by the control lever, the round head of the clutch arm gets into the notch on the driven rod, so that the driving rod is connected with the driven rod, consequently, the driven rotary shaft is rotated along with the driving rotary shaft to drive driven wheels to turn, and thereby the four wheels of the vehicle can turn.
Description
Technical field [0001] The invention relates to a two-wheel and four-wheel steering switching mechanism of a vehicle. Background technique [0002] At present, existing vehicles, especially agricultural vehicles such as sprayers, use two-wheel or four-wheel steering. Two-wheel steering is not convenient for farmland operations due to its large steering radius. Too small a radius makes maneuvering difficult. Contents of the invention [0003] In order to overcome the defect that the existing agricultural vehicles can only steer with two or four wheels, the present invention provides a switching mechanism for two-wheel and four-wheel steering of the vehicle, which can easily realize the conversion between two-wheel steering and four-wheel steering. [0004] The technical solution adopted by the present invention to solve its technical problems is: the driving arm is fixed on the driving shaft, the driving pin is fixed on the driving arm, one end of the driving rod is hinged...
