Description

Anti-overturned three-wheeled motor vehicle

The invention relates to a three-wheeled motor vehicle, in particular to an anti-overturning three-wheeled motor vehicle with agile and high safety.

Taiwan’s population density is the world’s highest, and there are quite a few locomotives with locomotives as the main means of transportation. Many roads are not conducive to driving conditions, such as: slippery road surface, loose sand on the road surface, gravel, uneven road surface, rough road surface, muddy road surface, or the design of the road to the narrow terrain, steep slope or large turn. It is a common cause of traffic accidents in Taiwan and even other countries. The traditional design of the three-wheeled vehicle control method, in the face of the above-mentioned many road conditions, it is very easy to lead to runaway or even overturned unfortunate accidents. However, there is no effective way to avoid the aforementioned loss of control or overturning accidents in the traditional designs currently on the market. As disclosed in U.S. Patent No. 5,116,069, the motor vehicle disclosed in the patent must utilize a hydraulic pump to control the left and right hydraulic cylinders to tilt the vehicle. Such design must provide additional power, not only the mechanism is complicated, The cost is also higher. Furthermore, as disclosed in Taiwan Patent No. I274677, the inward tilting mechanism is a trapezoidal four-link, which causes a change in the width of the slant when tilted inwardly, and the change in the width of the slant will cause an increase in the difficulty of driving control of the inward and backward, and at the same time, due to the patent The suspension system is independent of each wheel, so it will also affect the angle of inward tilt, but it will affect the safety of driving.

A small number of new-controlled three-wheeled vehicles are now available abroad, such as Piaggio MP3 or Carver. The Piaggio MP3 is a front two-wheeled motor vehicle that causes the left and right wheels to be dragged sideways during steering, causing tire wear and other disadvantages. Although Carver is the latter two-wheeled motor vehicle, the latter two rounds can not only be tilted, but both of them use a number of complicated electronic sensors, electronic controllers and even use computers to calculate and drive. The cost is very expensive, and once In the event of a malfunction, it is feared that the driver alone can avoid losing control. These vehicles not only become the noble leisure toys of the nobles, but also can not truly become the auxiliary action tools for the people's livelihood and benefit the vulnerable groups, and the everyday transportation of the approachable people.

Therefore, in order to improve the safety of motor vehicles in response to the above-mentioned many road conditions, and to benefit the disadvantaged groups that are weaker and have lower incomes, and even for the general public to ride, enjoy the pleasure of easy driving, there is indeed It is necessary to develop an anti-overturned three-wheeled motor vehicle with a simple and low cost mechanism.

Excellent security.

The anti-overturning three-wheeled motor vehicle of the present invention has a frame, a front wheel and a rear two-wheel assembly, and the rear two-wheel assembly includes an inward tilting base and a parallel four-bar linkage mechanism. The inward tilting base is coupled to the frame through a first mounting bracket. The parallel four-bar linkage mechanism is configured to connect the tilting base and the two rear wheels, and includes a first link, a second link, a third link, and a fourth link. The first link is pivotally connected to the tilting base, and is rotatable relative to the tilting base. The second link is disposed in parallel below the first link, and is also pivotally connected to the tilting base and is rotatable relative to the tilting base. The third link and the fourth link are respectively pivotally connected to the two ends of the first link and the second link, and are respectively connected to the suspensions of the two rear wheels, and the anti-overturning three-wheeled motor vehicle of the present invention further includes There are two shock absorbers for pivoting to the frame through the second fixing frame, so that the two rear wheels can be tilted with the frame, and when the frame is inclined, the tilting base, the first fixing frame and the second The shock absorber will be tilted with the frame, the first link and the second link will maintain a fixed angle with the road surface, and the third link and the fourth link will be tilted with the frame so that the second rear wheel also The frame is tilted. In addition, while the width of the ridge between the two rear wheels remains unchanged, the shock absorber can also make the parallel four-bar linkage mechanism shock-absorbing.
