A cambering vehicle includes a front column, and a bracket rotatably attached to the front column with a pivot shaft, a left and a right trailing arm each having a front portion pivotally attached to the bracket with a pivot axle which is preferably inclined relative to the bracket or the front column. A detachably latching device may be used to detachably latch the bracket and thus the trailing arms to the front column at the working position. The bracket and thus the trailing arm may be rotated relative to the front column to the folding position when the detachably latching device releases the bracket relative to the front column.

1. A cambering vehicle comprising:a front column, a bracket rotatably attached to said front column with a pivot shaft, to allow said bracket to be rotatable relative to said pivot shaft, and rotatable toward said front column to a working position, and rotatable away from said front column to a folding position, said bracket including a longitudinal axis, a left and a right trailing arm each including a front portion pivotally attached to said bracket with a pivot axle, and each including a rear portion having a rear wheel attached thereto, and each including a foot pedal disposed thereon to support users, and means for detachably latching said bracket and thus said left and said right trailing arm to said front column at said working position, said bracket and thus said left and said right trailing arm being rotatable relative to said front column to said folding position when said detachably latching means releases said bracket relative to said front column. 2. The cambering vehicle as claimed in claim 1, wherein each of said front portions of said left and said right trailing arms includes a bushing attached thereto and rotatably attached onto said pivot axles respectively.3. The cambering vehicle as claimed in claim 1, wherein said pivot axles are inclined relative to said longitudinal axis of said bracket.4. The cambering vehicle as claimed in claim 1, wherein said front column includes a front tube, a steering shaft rotatably disposed concentrically within said front tube, a front wheel provided on bottom of said steering shaft, and a handle provided on top of said steering shaft.5. The cambering vehicle as claimed in claim 4, wherein said steering shaft includes a stem adjustably disposed thereon to adjustably support said handle on said steering shaft.6. The cambering vehicle as claimed in claim 1 further comprising means for braking said rear wheels.7. The cambering vehicle as claimed in claim 1 further comprising means for coupling said left and said right trailing arms together.8. The cambering vehicle as claimed in claim 7, wherein said coupling means includes a link pivotally coupled between said left and said right trailing arms.9. The cambering vehicle as claimed in claim 8, wherein said link includes a first end pivotally secured to one of said left and said right trailing arms with a pivot pin, and a second end pivotally secured to the other of said left and said right trailing arms with a latch pin.10. The cambering vehicle as claimed in claim 8, wherein each of said left and said right trailing arms includes at least one ear provided thereon, and said link includes two ends pivotally secured to said at least one ear of said left and said right trailing arms with pins.11. The cambering vehicle as claimed in claim 1, wherein said bracket includes two socket openings formed therein, said front portions of said left and said right trailing arms are rotatably secured in said sock et openings of said bracket with said pivot axles respectively.12. The cambering vehicle as claimed in claim 11, wherein said bracket includes two frames provided therein to define said socket openings thereof respectively.13. The cambering vehicle as claimed in claim 1, wherein said detachably latching means includes a latch device attached to said front column, to selectively engage with said bracket, and thus to selectively secure said bracket to said front colunm at said working position.14. The cambering vehicle as claimed in claim 13, wherein said front column includes an extension extended therefrom to support said latch device, said latch device includes a latch pin extended through said extension of said front column.15. The cambering vehicle as claimed in claim 13, wherein said bracket includes a panel having an orifice formed therein, said latch device includes a latch pin extended therefrom and engageable into said orifice of said panel, to detachably secure said panel and said bracket to said front column.
