Embodiment

As shown in Figure 2, main body of the present utility model is the mainframe 1 that parts such as direction machine assembly and seat are housed.Be provided with in the middle of mainframe 1 rear portion and turn to traction component 3.

As shown in Figure 3 and Figure 4, below mainframe 1, locate hinged by pin joint 10 and 11 liang the rear frame of the rear end of movable frame 2 and mainframe 1.Damping spring or leaf spring 5 are installed in the bearing 12 of movable frame 2 and the bearing 14 of mainframe 1, and damping spring or leaf spring 6 are installed in the bearing 13 of movable frame 2 and the bearing 15 of mainframe 1.Movable frame 2 is around pin joint 10 and 11 reciprocally swingings, and damping spring 5 and 6 is flexible thereupon, forms the swing arm suspension.As shown in Figure 4, in the postmedian position of movable frame 2 engine 9 is housed, in the forward position of movable frame 2 vehicle bridge 4 is housed, the outputting power of engine 9 drives wheel by transmission system 30 through vehicle bridge 4.

Turn to the function of traction component 3 to be: in conjunction with separating trailed trailer or all kinds of farm machinery, to keep the utility model and the front and back longitudinal balance that is pulled body, make the two realize articulated steering, and coordinate the road worthiness of the two.In conjunction with Fig. 5 and shown in Figure 6, turn to the critical piece of traction component 3 to turn to sleeve pipe 17, drag spring thimble 18 turns to swing arm 19, trunnion axis 20 and U-shaped deck 21, vertical bearing pin 22.To turn to sleeve pipe 17, trunnion axis 20 and turn to swing arm 19 to be combined into a global facility.Vertical bearing pin 22 passes the hole up and down of U-shaped deck 21, and thrust bearing 23 turns to sleeve pipe 17 and thrust housing 24.Trunnion axis 20 passes thrust housing 25, drag spring thimble 18 and thrust housing 26.Nut 27 and 28 is used for respectively locking and the adjustment fit clearance.U-shaped deck 21 and mainframe 1 secure bond.Turn to swing arm 19 and steering linkage 8 to connect (as shown in Figure 3) with direction machine plumbing arm 7 by ball stud.Drag spring thimble 18 and Connection Block 29 be combined as a whole (Connection Block 29 can be a flange).Utilize Connection Block 29 in conjunction with separating trailed trailer or all kinds of farm machinery as shown in Figure 1.
