Abstract

PURPOSE:To achieve excellent cornering characteristic by steering one rear wheel with correspondense to the steering of a pair of front wheels in the direction reverse from the steering direction of front wheel while moving to the side opposite from the turning side of car. CONSTITUTION:A three-wheeled vehicle 1 is provided with two front wheels 2 and one rear wheel 3 and an engine 6 is mounted in the front chassis 4. The engine 6 power is transmitted from the output shaft 7 through an equi-speed joint 8 to the left/right front wheels 2. A pitman arm 10 is secured to the lower end of the steering shaft 9 where one arm 10a is coupled through a tierod 11 to the knuckle arm 12 while the other arm 10b is coupled through a rod 13 to a pair of rear forks 14. The interval of vertical pins 21 at the leading edge is set shorter than that of a pair of vertical pins 16 at the base of the rear fork 14. Consequently the required function can be achieved.

Description

[Detailed description of the invention]

Opening the book box, this is a picture of an L7C three-wheeled vehicle with a left and right -1IL front wheel installed on the niJ side: one σ at the rear. ?!i?σ] Three-wheeled vehicle Compared to the three-wheeled vehicle, the light ii'J has a simpler structure, so it has lower fuel consumption and is less expensive. It has been in practical use for a long time as a small-sized traveling unit. The present invention (q) shown in Figs. 1 to 41 below is the present invention q).

In addition, by turning the steering wheel (not shown), the front wheels 26 are steered left and right, and the rear wheels 3 are steered in the opposite direction.

Therefore, when applying the vehicle, a perpendicular line σ drawn from the center of gravity of the three-wheeled vehicle to a line that connects the outer front two wheels σ] slave point and the grounding point of the rear-@] is long when the rear-axle is fixed. 1. It is longer than the vehicle, and it can run smoothly at high speeds and has excellent cornering characteristics.Moreover, due to the reverse direction steering G of the rear stop shaft, the rear single wheel is on the side opposite to the vehicle turning side. Movement is performed smoothly and comfortable steering is possible.
