The front frame of the frame is pivotally connected to the steering device 3, and the lower portion of the switchboard 3 is provided with a = wheel 22 in the steering device 3 After that, the seat unit 3 is provided with a seat portion 2 3 0 times. Please refer to the steering device 3 of the present invention as shown in FIG. Including the side 200911596 to the disc 3 1, the steering column 3 2, the middle rod 33 and the - direction machine 4, the steering wheel 31 is fixed on the upper end of the steering column 3 2, the lower end of the steering column 3 2 by - Wan Connected to the intermediate rod 3 3 to the joint 34, the lower end of the intermediate rod 3 3 is connected to the screw 42 of the steering machine 4 by another universal joint 34, and the steering machine 4 has a body 4 1. The main body 4 1 is hollow. The left side of the main body 42 is provided with an opening upwardly facing hole 41 ^. The sleeve hole 41 is slightly inclined with the main body 41 in a four-page configuration. 41 is provided for a rack 4 3, a screw 4 2 is accommodated 'the rack 43 has a - helical section 4 31 and is inserted into the body 41 in the same direction as the body 4!, the screw 4 2 The lower end has a threaded section 4 2 i, and is inserted into the body 4丨 by the sleeve hole 4 i of the body 41, the rack 4^=the tooth section 4 3 1 and the threaded section 4 2 of the screw 4 2 The inner body of the body 4 1 is exploded, and the ends of the w 4 4 3 are respectively connected to the steering rod 5, and the steering rod 5 is screwed to the rack 43 by a ball type joint 51, and the ball joint 5 is arranged on the outer side of the rack There is a anti-Songhua Division 5 2 'Mixed Rod 5 with The body 4 is connected with a wealthy dust jacket 7 to prevent dust or water from entering the body of the body 4, and is respectively connected to the lock shaft of the front wheel 2f of the vehicle (not shown in the drawing), and the body 4 1 The first side of the two sides is set - the step difference, = 1 2 'The miscellaneous part 4 1 2 is suitable for the wire 6, which is made by the witch material of the door 3 The rack 4 3 moves as a branch, and the V strip 4 3 avoids the body 4 i when moving; the rotation of the steering rod 32 and the intermediate rod 3 3 can be synchronously rotated by the rotation direction 2 Rotating the screw 4 2 of the machine 15, the screw 4 2 can drive the rack 4 3 200911596 to move, and make the secret 4 3 move left and right in the body 4 i, when the rack 43 moves left and right, it can be mixed The swinging lever 5 is used as a left pillow. The steering rod 5俾: pulls the other wheel 22 to actuate 'by this, the front wheel 22 of the vehicle can be changed in steering angle, thereby changing the traveling direction of the vehicle. As shown in Figures 5 and 6, since the left and right movements of the steering machine 4 are the same, the right half of the steering machine 4 is taken as an example for illustration; the four-wheeled vehicle of the present invention is turned to the frame, the front wheel 2 2 turn shouting large compilation, _ to the tie rod wrapped in the ball head 5 1 outside the anti-Songhua Division 5 2, into the body of the body 4 丄 inside = from the set of 6 distance D; as shown in Figure 6, It is indicated that the anti-songs main body 41 is in the top of the sleeve 6, that is, the maximum angle of the front wheel 22 is turned === the restriction mechanism of the four-wheeled vehicle steering device is covered by the ball=51 Level exposure 5 Ί 蝴 蝴 状 状 状 状 状 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前The thick shaft sleeve 6 can reach the maximum deviation of the county wheel 2 2 change project. = The effect is that the body 4i of the steering machine 4 is provided with a step difference portion 4, the difference portion 4 12 is just available for the sleeve (four), and the steering rod 5 is fixed to the outer side of the ball joint 51. Into the body 41 to come, II butterfly 2 2 turn _ wall delete point, made of the shaft sleeve 6 is made of high-hardness metal material, so when the ball joint 5 work outside the lock (four) 52 into the body 41 Internal impact _ set (four), borrow _ set 6 200911596 itself has _ shape, then the body of the directional machine 4 4 i will be covered by the steering rod 5 on the outside of the ball joint 5 i against the Songhua Division 5 2 hit The loss is caused by the loss, and at the same time, when the maximum angle of the front wheel 2 2 is changed, the direction of the machine 4 needs to be changed (4), and the cost of the change project can be effectively reduced. In summary, the invention can achieve the effect and purpose of the claim by the above-mentioned four-wheel steering device limitation mechanism, and should have met the requirements of the new brewing and progressiveness, ' 爰 Applying for the invention patent according to law, riding # The examiner, Huisei granted the examination and approval of the invention patent, to the sense of virtue.
