The kind of face control agile, female [prior technology] Taiwanese sigma density is the world's highest in the world. Many roads with locomotives are not conducive to driving. For example: road == to the road, the design of the terrain is narrow, and the slope is steep. Muddy, or to its #国定坡, steeply and sharply turned 'in Taiwan, and other countries _ material-induced traffic accidents, the normal control of the car, facing the above-mentioned many roads and the current traditional design on the market, there is no Effective «« method of accident. As disclosed in U.S. Patent No. 5, ιΐ6, 嶋i 利, the motor vehicle disclosed in the patent must utilize the dust pump to control the left and right (four) cylinders to tilt the vehicle, and such design must provide additional power. Not only the organization is complicated, but also the cost is high. Furthermore, as for Taiwan's Announcement No. 74677, the inward tilting mechanism is a trapezoidal four-link, which causes a change in the width of the raft when it is tilted, and the change in the width of the slant will cause difficulty in driving control of the inversion and returning. The shock absorber system of this patent is independent of each wheel, so it will also affect the angle of inward tilt, but it may affect the safety of driving. • A small number of new-controlled three-wheeled vehicles are now available abroad, such as Piagg1〇 MP3 or Carver. The piaggi〇 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 201125760 to calculate and drive the computer, which is very expensive. In the event of a malfunction, it is feared that the driver alone can avoid losing control. These vehicles are not only a high-class leisure toy for the nobility, but also can not truly become an auxiliary driving tool for the people and the disabled, and the daily transportation of the approachable and vulnerable 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. SUMMARY OF THE INVENTION The main object of the present invention is to provide an anti-overturning three-wheel drive, but the mechanism is simple and the cost is low.

Great security. 8. The anti-overturned three-wheeled motor vehicle of the present invention has a frame, a front wheel and a rear two-wheel assembly, the rear two-wheel assembly including an inverted base and a parallel four mechanism. The inward pedestal base, the through-the first fixed frame is connected to the frame linkage mechanism for connecting the tilting base and the second rear wheel, and includes a first link, a third link and a fourth link. The first link is connected to the inner tilt base 3rd=3 inner tilt base and is rotatable. The second link is parallel to the lower side, which is also connected to the inverting base, relative to this. The third link and the fourth link are respectively pivotally connected to the two ends of the first and the first connection, and are respectively connected to the suspension of the second rear wheel, and the anti-overturning three-wheeled motor vehicle of the present invention is inserted into the The steps include having two shock absorbers ^ passing the second truss and (4) on the frame, and tilting the material. When the frame is tilted, the tilting base, the first-fixing frame and the production, the first raft and the road are maintained. The fixed angle and the second and fourth links will be tilted with the frame so that the second rear wheels are also tilted with the 201125760. In addition, while the width of the sill between the two rear wheels remains the same, the shock absorber can also make the parallel four-bar linkage mechanism shock-absorbing.

The parallel four-bar linkage 1 is used to connect the frame 1 and the rear wheel 2 (described in detail later). When the anti-overturning three-wheeled motor vehicle of the present invention turns, the parallel four-bar linkage mechanism 100 not only maintains the stability of the frame 10 when it is tilted inward, but also utilizes the characteristics of the parallel two-connected mechanism 100 to ensure the second round of the second wheel 2 The width is kept constant. Therefore, it can not only avoid the abnormal wear of the tires due to the different angles of the inward tilt and the inversion of the inner tilt, and also improve the sensitivity of the body tilting and returning. Please also refer to Figures 3 to 5 of the present invention. Fig. 3 is a perspective view showing a parallel four-bar linkage machine 100 of the first embodiment of the anti-overturning three-wheeled motor vehicle of the present invention. Fig. 4 is a rear elevational view showing the parallel four-bar linkage mechanism of the first embodiment shown in Fig. 3 of the present invention. Fig. 5 is a view showing a state in which the parallel four-bar linkage of the first embodiment shown in Fig. 3 of the present invention is tilted. In the first embodiment, the anti-overturning three-wheeled motor vehicle of the present invention comprises a row of four-bar linkages and a tilting base 1〇2.

In this embodiment, the anti-overturning three-wheeled motor vehicle of the present invention includes two shock absorbers 216' which are inserted into the frame 1' through the fixing frame 204, and are towed to the inverting base at 201125760. 202' presents a state in which it can be rotated relative to the parallel four-bar linkage 200. Moreover, the anti-overturned three-wheeled motor vehicle system of the present invention further includes a hydraulic system having two hydraulic components 220. As shown, one end of the hydraulic element 220 is coupled to the T-joint 218, and the other end of the hydraulic element 220 is respectively framed with the second second link 208-1 'the second second link 208-2 ( The first hydraulic connecting rod 206-1 and the left first connecting rod 2〇6_2 may be pivoted. When the frame 1 is tilted, the two hydraulic components 220 may be connected to the two parallel four-bar linkages (ie, The right first link 206-1, the left first link 2〇6_2, the right second link 2〇81, and the left second link 208-2). Referring to Figure U, there is shown a schematic view of all of the hydraulic components 220, the oil pipe 222 and the solenoid valve 224 of the hydraulic system of the second embodiment of the present invention. In this second embodiment, it further has a hydraulic system including hydraulic cylinders of two hydraulic components 22, as shown in FIG. 9, the hydraulic cylinders are vertically mounted to the T-frame 218 and the first floor with respect to the ground. Between the two links 208 (and the first link 2〇6). There is a tubing 222 between the two hydraulic cylinders for connecting the two hydraulic cylinders. As shown in Fig. 11, the oil pipe 222 further includes a solenoid valve 224 for controlling the flow of the oil pipe 222 between the two hydraulic cylinders, and locking the inclination angle of the rear two wheels 2. That is, when the anti-overturning three-wheeled motor vehicle of the present invention is parked, if the parking ground is a slope or a slope with an inclined angle, the driver can control the switch of the electromagnetic valve 224, and adjust one of the left and right hydraulic cylinders to expand and contract, that is, can cooperate A slope or slope with an angle of inclination that maintains the vehicle body in a vertical position when parked on a slope or ramp. Referring to Fig. 12, there is shown a rear perspective view of the inner tilt base 2, the holder 204 and the shock absorber 216 of the second embodiment of the present invention. As shown in the figure, the second embodiment of the present invention utilizes the linear chute 226, so that the inward tilting base 2 can slide up and down in the linear chute 226, thereby causing the fixing frame 2〇4 and the shock absorber 216. It is also possible to move up and down, so that the parallel four-bar linkage mechanism 2 (9) of the present invention has a shock absorbing effect. Moreover, the shock absorber 216 and the hydraulic component 220 of the second embodiment adopt the manner in which the rear two wheels 2 are integrated, so that the angle of inclination of the vehicle body is not affected or the width of the second wheel 2 is changed. Comparing Fig. 9 and Fig. 10, when the anti-overturning three-wheeled motor vehicle of the present invention turns to 201125760 buttocks and the frame 10 is tilted, the inner tilting base 202, the fixed frame 204, the second shock absorber 216, and the T-shaped connecting frame 218 And the two hydraulic components 220 will follow the frame! While tilting, the right first link 206-b left first link 206-2, right second link 208", left second link 2〇8_2 will maintain a horizontal state, and as in the first The second embodiment of the present invention, with the black arrow 220', can be used to make the right first link 206-1 and the left first link by the relative expansion and contraction of the right and left hydraulic cylinders. 2〇6_2, the right second link 2〇8 and the left second link 2〇8 2 are interlocked to maintain the horizontal state. The third link 21〇 and the fourth will be inclined with the tilting base 2〇2 and the frame 1() so that the two rear wheels 2 can be tilted with the frame 1〇, so that the two rear wheels 2 can be The width remains the same. Therefore, this, the anti-overturned three-wheeled motor vehicle can not only combine the intrinsic performance of the two-wheeled vehicle and the erect stability of the tricycle, but also has the disadvantages of easy slipping of the two-wheeled vehicle and easy folding of the two-wheeled vehicle, so as to provide excellent riding control. safety. While the present invention has been described above with respect to the preferred embodiments, it is not intended to limit the scope of the invention, and various modifications and changes can be made without departing from the scope of the invention. Therefore, the protection of this month is defined by the scope of the patent application.
