Claims

[Scope of utility model registration request]

The front vehicle body 21 and the rear vehicle body 22 are provided with traveling devices 1 and 5, respectively, and the two vehicle bodies 21 and 22 are connected so as to be relatively rotatable around the front and rear axis Y, and relatively swingable around the vertical axis X. The two vehicle bodies 21 are connected freely.
.
, 22 about the vertical axis , 22 vertical axis center X
Rolling regulation angle switching means that automatically switches the relative rocking angle around the body to a large value when it is below a certain level and to zero or small when it is above a certain level, and the body bending control device 28. The swing range is
Body bending restriction angle switching means that automatically switches the relative rotation angle of both vehicle bodies 21 and 22 around the longitudinal axis Y to a larger value when it is zero or less than a certain value, and to a smaller value when it is greater than a certain value. A work vehicle equipped with
