Embodiment Construction

[0032] Next, an embodiment of the automatic tricycle according to the present invention will be described with reference to the drawings.

[0033] figure 1 The automatic tricycle 1 shown has: a car body 10; a front wheel 12, which is installed on the car body 10 and is steered through a handlebar 11; The rear is driven; a pair of left and right driving mechanisms 13R, 13L, which drive a pair of left and right rear wheels 14L, 14R respectively; a steering angle detection mechanism 21, which is used to detect the steering angle θ of the handlebar 11; a speed detection mechanism 22, which uses For detecting the traveling speed V of the vehicle body 10; the control unit 30.

[0034]Assuming that no slip occurs between the left and right rear wheels 14L, 14R and the road surface when the vehicle body 10 is turning on a curved road through the turning operation of the handlebar 11, the control unit 30 will When the speed is V1 and the steering angle θ is greater than or equal to t...

Abstract

The present invention provides an automatic tricycle capable of improving turning performance without using a differential gear and an active suspension system. The automatic tricycle includes a control unit. When the vehicle body is turned on a curved road through the rotation operation of the handlebar, under the assumption that there is no slippage between the left and right rear wheels and the road surface, when the driving speed (V) is greater than or equal to the specified speed (V1) and the steering angle (θ) is larger than the specified angle (θ1), the control unit adds the driving speed (V) and the steering angle (θ ) corresponding to the additional speed ratio (Rd1), the outer wheel is driven by the driving mechanism, and the required speed ratio (R0) of the outer wheel is based on the handlebar detected by the steering angle detection mechanism The resulting steering angle (θ) is the desired rotational speed ratio of the outer wheel relative to the inner wheel.

Description

technical field [0001] The invention relates to an automatic tricycle (hereinafter also referred to as a tricycle for short). Background technique [0002] Compared with two-wheeled vehicles, auto-tricycles can carry a larger amount of cargo, and are also superior to two-wheeled vehicles in terms of stability when stopped. Compared with four-wheel vehicles, although the amount of cargo carried is smaller, three-wheel vehicles are better than four-wheel vehicles in terms of flexibility when turning. [0003] Therefore, tricycles are most suitable for use when distributing or carrying heavy goods such as beer and kerosene on narrow roads, as well as bulky mattresses that cannot be carried by two-wheeled vehicles. [0004] Thus, from the 1950s to the 1960s, relatively large (for example, about 150 cm in overall height, about 120 cm in width, and 250 cm in length) automatic tricycles were often used. However, the auto-tricycles of the time had poor cornering performance and we...
