As shown in Figure 5, when bicycle becomes three-wheel vehicle:
When the variable rickshaw initial condition of high-mobility, multipurpose, wheeled vehicle is bicycle, left back translation frame 5 is in the position of upwards turning up 90 °, locating dowel pin 14 turns over 5 be fixed on C shape frame 8 by left back, left rear wheel is above off hind wheel, parallel-crank mechanism I 1, parallel-crank mechanism II 2, parallel-crank mechanism III 3, parallel-crank mechanism IV 4) be all in long limit and the orthogonal state of minor face (i.e. rectangle), locating dowel pin 15 is by parallel-crank mechanism I 1 and parallel-crank mechanism II 2 pinning, and tie-beam 9 and transmission shaft 10 are all parallel with symmetrical.
The mistake that bicycle becomes three-wheel vehicle is called: unclamp locating dowel pin 15, by parallel-crank mechanism I 1, parallel-crank mechanism IV 4 is out of shape certain angle left, parallel-crank mechanism II 2, parallel-crank mechanism III 3 is out of shape to the right and parallel-crank mechanism I 1, the angle that parallel-crank mechanism IV 4 is the same, with locating dowel pin 15 by parallel-crank mechanism I 1 and parallel-crank mechanism II 2 pinning, unclamp locating dowel pin 14, left back translation frame 5 is upset 90 ° downwards, with locating dowel pin 13, left back translation frame 5 is fixed on C shape frame 8 again, tie-beam 9 overturns 90 ° to the right and is connected with right back frame 6.
As shown in Figure 4, when three-wheel vehicle becomes bicycle:
When the variable rickshaw initial condition of high-mobility, multipurpose, wheeled vehicle is three-wheel vehicle, left back translation frame 5 is in the position of turnover 90 ° downwards, and left back translation frame 5 is fixed on C shape frame 8 by locating dowel pin 13, left rear wheel and off hind wheel wheel shaft point-blank; Parallel-crank mechanism I 1, parallel-crank mechanism II 2, parallel-crank mechanism III 3, parallel-crank mechanism IV 4 are all in long limit and the not orthogonal state (i.e. parallelogram) of minor face, and the angle that parallel-crank mechanism II 2, parallel-crank mechanism III 3 are out of shape to the right is the same with the angle that parallel-crank mechanism I 1, parallel-crank mechanism IV 4 are out of shape, locating dowel pin 15 is by parallel-crank mechanism I 1 and parallel-crank mechanism II 2 pinning; Tie-beam 9 and right back frame 6 are connected to; Transmission shaft 10 bends with the distortion of parallel-crank mechanism.
The process that three-wheel vehicle becomes bicycle is the connection of unclamping tie-beam 9 and right back frame 6, and tie-beam 9 overturns 90 ° left; Unclamp locating dowel pin 13, left back translation frame 5 is in upwards turns up 90 °, is fixed on C shape frame 8 with locating dowel pin 14 by left back translation frame 5; Unclamp locating dowel pin 15 again, parallel-crank mechanism I 1, parallel-crank mechanism IV 4 are out of shape certain angle to the right, parallel-crank mechanism II 2, parallel-crank mechanism III 3 are out of shape left and parallel-crank mechanism I 1, angle that parallel-crank mechanism IV 4 is the same, parallel-crank mechanism I 1, parallel-crank mechanism II 2, parallel-crank mechanism III 3, parallel-crank mechanism IV 4 is made all to be in long limit and the orthogonal state of minor face (i.e. rectangle), with locating dowel pin 15 by parallel-crank mechanism I 1 and parallel-crank mechanism II 2 pinning.
