Embodiment 1
[0059] The first embodiment discloses a articulated mechanism for articulated special vehicles, such as figure 1 and figure 2 As shown, the vehicle articulation mechanism is connected between the rear vehicle body 5 and the front vehicle body 16, and is a left-right symmetrical structure. Including mobile hinged support 1, horizontal oil cylinder 1, horizontal oil cylinder 2 3, mobile hinged support 2 4, left steering cylinder 6, fixed hinged support 2 7, left pitch cylinder 8, fixed hinged support 4 9, mobile Articulated support four 10, transverse oil cylinder four 11, right pitch oil cylinder 12, fixed hinged support three 13, transverse oil cylinder three 14, mobile hinged support three 15, right steering oil cylinder 17 and fixed hinged support one 18.
[0060] The first transverse oil cylinder 2 and the second transverse oil cylinder 3 are symmetrically installed on the rear body 5 of the vehicle. A rectangular horizontal oil cylinder mounting groove is provided at th...
Embodiment 2
[0083] Embodiment 2 discloses an articulated vehicle, such as Figure 7 Shown, described vehicle is made up of front body 16, rear body 5 and articulation mechanism 19. Described articulated mechanism 19 adopts the special vehicle articulated mechanism described in the above-mentioned embodiment one. The hinged mechanism 19 is installed and connected between the front vehicle body 16 and the rear vehicle body 5, and under the control of the hinged mechanism 19, the vehicle realizes steering, pitching and twisting actions.
[0084] The steering action of the vehicle is realized through the active expansion and contraction of the steering oil cylinder. The specific implementation process is: the vehicle actively expands and contracts the horizontal oil cylinders on the front and rear car bodies, and then drives the left and right steering oil cylinders to expand and contract, so that the rear body is relatively The front body swings, or the front body swings relative to the rea...
Embodiment 3
[0089] Embodiment 3 discloses a steering control method for an articulated vehicle. The articulated vehicle is the vehicle in Embodiment 2 above. The special vehicle described in Embodiment 1 is installed between the front body and the rear body of the articulated vehicle. Articulation mechanism.
[0090] The steering control method of the vehicle includes: "the front body rotates at a large angle and the rear body rotates at a small angle", "the rear body rotates at a large angle and the front body rotates at a small angle" and "the front and rear bodies rotate at the same angle". Steering control method; where:
[0091] like Figure 8a and Figure 8b As shown, the steering control process of the front vehicle body rotating at a large angle and the rear vehicle body rotating at a small angle is as follows:
[0092] like Figure 8a As shown, the horizontal oil cylinder one 2 and the horizontal oil cylinder two 3 respectively pull the movable hinged support one 1 and the mo...
