PCT No. PCT/GB85/00395 Sec. 371 Date May 2, 1986 Sec. 102(e) Date May 2, 1986 PCT Filed Sep. 4, 1985 PCT Pub. No. WO86/01479 PCT Pub. Date Mar. 13, 1986.The vehicle has a main chassis (2) pivotally supported by front and rear sub-chassis (1,6), one of which carries the engine. Constant velocity power is communicated between the two sub-chassis (1,6) by an intermediate shaft (20) connected to front and rear shafts (18,21) extending along the center-lines (1',6') of the respective sub-chassis (1,6). For steering, pivoting of the rear sub-chassis (6) is controlled in dependence of the pivoting of the front sub-chassis (1) so that, during, turning, the center-lines (1',6') of the sub-chassis intersect at a point (61) nearer to the pivot axis (27) of the front sub-chassis (1) than to the pivot axis (30) of the rear sub-chassis (6). The universal joints (20a,20b) of the intermediate shaft (20) are equidistant from the intersection point (61). The rear sub-chassis (6) thus pivots through a smaller angle than the front sub-chassis (1). |
