Rear wheel adjustable steering mechanism suitable for semi-trailer launching vehicle

Abstract

The invention discloses a rear wheel adjustable steering mechanism suitable for a semi-trailer launching vehicle. The rear wheel adjustable steering mechanism suitable for the semi-trailer launching vehicle comprises wheels (1), a rear first axle steering trapezoidal part (2), a rear first axle pull arm (3), a pull rod A (4), a rear second axle pull arm (5), a rear second axle steering trapezoidal part (6), a pull rod B (7), a rear third axle pull arm (8), a rear third axle steering trapezoidal part (9) and a driving oil cylinder (10). The driving oil cylinder (10) drives the rear second axle pull arm (5) to rotate around a fixed hinge pin; through the pull rod A (4) and the pull rod B (7), the rear first axle pull arm (3) and the rear third axle pull arm (8) rotate around corresponding shafts, therefore, positions of the rear first axle steering trapezoidal part (2), the rear second axle steering trapezoidal part (6) and the rear third axle steering trapezoidal part (9) are changed, the rear three-axle vehicle wheels steer according to a certain angle, the minimum passing radius of the vehicle is reduced, and the passing ability of the vehicle is improved; and meanwhile, friction between the wheels and the ground is reduced during steering, and the reliability of the wheels is improved.

Description

technical field [0001] The invention relates to a rear wheel adjustable steering mechanism for a semi-trailer type multi-axle vehicle, in particular to a rear wheel adjustable steering mechanism suitable for a semi-trailer launch vehicle. Background technique [0002] The medium and long-range ground-to-ground ballistic missile weapon system has many advantages such as long range, strong defense penetration capability, high strike precision, and strong damage capability. It is an important means to achieve long-range precision strikes in modern high-tech warfare. Significant enhancement of detection capabilities and rapid strike capabilities is an important trend in the development of future warfare, which poses severe challenges to the survivability of medium- and long-range surface-to-surface ballistic missiles. Improving the strategic maneuverability of missile weapons is an important way to improve survivability. [0003] With the increase of the range of the missile, t...
