Abstract

As shown in an embodiment of Figure 1, the present invention relates to a frame for a tilting car or a tilting three-wheeled motor cycle tilted toward the center of a turning radius like a motor cycle when the tilting car or the tilting tricycle corners. Figure 3 shows a microcompact car which has three or more wheels with narrow width, and the same advantages as a two-wheeled motor cycle by including a tilting link device using the unique motion of a trapezoid or a turned trapezoid figure for a car to be tilled toward the center of a turning radius of the car. However, it is important that a tilting car, using a number of rotational joints on a frame structure of the tilting car compared with a normal car, unlike conventional cars, has a strong connection between tilting devices moving side to side and a body frame moving forward, because a weak connection is easily broken by resistance against off-road impact and when a rear-end collision and a collision occur. The frame is designed to maximize the movement of the center of gravity of a tilting car toward the center of the turning radius of the car and to have rotational joints used for each frame provided with a strong structure to withstand external impact. The safe, microcompact and ultralight tilting car of the present invention relieves traffic congestion and parking difficulties in a downtown area and reduces use of fossil fuel, thereby contributing to solve global warming and, in particular, to help commercialization of electric vehicles.

Tilting car frame {omitted}

Tilting cars, tilting motorcycles,

f300Life-jet (Germany-Benz). p67b eternity (Japan).

Moving center of gravity (KR, Yoo Jee Woo, Special Issue: 1996-0017431, 2007, Registration No. 10-0702188)

Refers to a vehicle that can be inclined inwardly of the turning radius to prevent it from being turned over by centrifugal force when the car is cornering, as shown in Fig. 1).

This tilting car is intended to be applied to small cars, which are mainly narrow, because they are designed to solve the urban pollution caused by the parking lot of the city, traffic accident, and the fuel consumption of four-wheeled vehicles.

However, the biggest problem with narrow-width compact cars is that when cornering, they can easily be reversed by centrifugal force.

Therefore, when cornering, it is possible to solve the above problem by developing a small-sized compact car which can be inclined inside the turning radius like a motorcycle.

However, in the cornering, when the tilting car is tilted to the inside of the turning radius, too much energy is also inefficient.

To solve this problem, applying a working principle of a square or triangle, especially a trapezoidal shape, can make a tilting car that can tilt even a very large car with very little power.

The world's first tilting car made using this geometric principle is my 'center of gravity moving car' designed in 1994.

Another problem that needs to be addressed in the design of tilting cars is the sense of ride.

It is because we are standing in an upright position and feeling a sense of stability when we are standing upright, standing in opposition to the direction of gravity.

However, when the car is cornering, as shown in Fig. 3), the direction of gravity moves obliquely to the side due to the resultant force with the centrifugal force.

Therefore, to make the occupant feel the same sense of stability as when standing upright, the seat must be inclined at an angle including the body frame of the tilting car so that the occupant can resist in the opposite direction to the tilted gravity direction .

Inside the built tilting car, even when the car is cornering, the water in the cup is not spilled.

And, as shown in the motorcycle race, the tilting angle must be very large in order for the small tilting car not to be completely inverted when cornering at high speeds.

Another big problem to be solved in the tilting car is that when cornering, there are parts that are inclined, non-tilted, and tilting angles, and each of these links has a rotating joint The durability of the rotating joints used in this way becomes a problem.

Therefore, several revolving joints should be designed so that they do not break easily even in case of continuous external impact from the ground of the off-road, collision with other vehicles or collision.

First, as shown in FIG. 3-A, a geometric principle applied to a tilting car is as follows. A rectangular link equipped with a revolving joint is formed at the upper part of a lower frame (FIG. 3-2) Next, when this is tilted, it can be seen that the link on the top side (FIG. 3-1) is parallel to the side only and is not tilted to the inside of the radius of rotation.

In this case, the body of the vehicle (Figs. 3-4) can be tilted, but when the vehicle is cornering, it is inconvenient for the occupant to resist the direction of gravity tilted obliquely by centrifugal force . That is, when cornering, the water in the cup inside the car is poured.

3B), an orthopedic link (a trapezoid whose upper side length is shorter than the lower side length) equipped with a rotary joint is formed on the upper part of the lower side frame (FIG. 3-2) When this is made to be inclined, it can be seen that the body of the car (Fig. 3-4) is inclined and the link on the upper side (Fig. 3-1) is inclined obliquely to be perpendicular to the direction of the oblique gravity. That is, when cornering, water in the cup inside the car is not spilled.

However, as can be seen from my own design in 1994, the advantage of this orthogonal trapezoidal linkage is that if the overall center of gravity of the car is designed to lie below the trapezoidal top link (Figure 3-1) The automobile is automatically tilted to the inside of the turning radius, while being pushed outwardly of the turning radius by the centrifugal force. Therefore, the force that makes the car tilt to the inside of the radius of turn is scarce.

However, as shown in FIG. 3-B, since the center of gravity of the automobile approaches the contact point between the wheel and the ground outside the turning radius, since the center of gravity of the automobile is close to the contact point between the ground and the ground, There is a disadvantage in that the resistance against turning over to the outside of the turning radius is not increased so much, which is disadvantageous for high-speed urgent cornering.

Therefore, in order to overcome the disadvantage of the above-mentioned orthogonal trapezoidal link, as shown in FIG. 3-C, an inverse trapezoidal link (a trapezoid whose upper side length is longer than the lower side length) is made and then tilted to the inside of the turning radius It can be seen that the body of the car (Figs. 3-4) tilts and the link of the upper side (Fig. 3-1) tilts so as to be perpendicular to the oblique direction of gravity.

The advantage of this inverse trapezoidal link is that the tilting car is tilted inwardly of the turning radius and at the same time the center of gravity of the car is moved away from the contact of the wheel to the ground outside the turning radius, Which is very resistant to being turned upside down.

However, the disadvantage of this inverse trapezoidal link is that, unlike an orthogonal trapezoidal link, the vehicle must be tilted inwardly of the radius of rotation with an artificial external force while resisting centrifugal force, There is a disadvantage that more force is required to tilt inwardly of the radius.

As shown in FIG. 3-D, if an inverted triangular link is made at the upper part of the lower side frame (FIG. 3-2), in which the length of the lower side of the inverted trapezoidal link is made zero, Effect can be obtained.

The advantage of this inverted triangle link is that it does not use a revolute joint in the connection of the upper link (FIG. 3-1) and the links on both sides (FIG. 3-2) It is necessary to use a rotating joint only in the connecting portion of the joint.

However, unlike an inverted trapezoidal link composed of two revolving joints, the lower side frame (Fig. 3-2) and the joint are composed of one revolving joint, so that, as mentioned above, In the event of a collision with another car, there is a disadvantage that the rotating joint can easily break down.

And although the center of gravity of the vehicle is away from the wheel-to-ground contact outside the radius of rotation, it is not as distant as a relatively reverse trapezoidal link device.

There is also a disadvantage that when the person gets on and off after the stop, the body becomes less stable.

However, when actually making a tilting car, as shown in FIG. 4), the link devices of the quadrangle, the normal trapezoid, the inverted trapezoid, or the inverted triangle are arranged on the lower frame (FIG. 3-2) As shown in FIG.

As shown in Fig. 4-E, by connecting the body frame (Fig. 4-4) of the vehicle body to the upper link (Fig. 4-1) The body frame of the vehicle body (Figs. 4-4) also tilts when tilted in the left-right direction of the vehicle body.

At this time, if the entire frame of the tilting car is completed by only connecting the upper link (FIG. 4-1) and the body frame (FIG. 4-4) of the quadrangle, the normal trapezoid, the inverted trapezoid, As shown in FIG. 4-E, in the event of continuous external impact from the ground of the off-road or collision with other vehicles or collisions, the joints and the turning joints can easily break down.

In order to solve this problem, as shown in FIG. 5-A, the lower side frame (FIG. 5-2) is elongated forward and then a plurality of separate rotary joints (FIGS. 5-5) . When connecting the body frame (Figs. 5-4), a plurality of revolving joints (Fig. 5A) on the upper link (Fig. 4-1) and the elongated lower side frame 5 - A), when the body frame (FIG. 4-4) is simultaneously connected, as shown in FIG. 5-A, in the event of continuous external impact from the ground of the off- And the rotating joints can be protected easily.

5-5) is extended to the forward side and then a plurality of separate rotary joints (FIGS. 5-5) are provided, the plurality of rotary joints (FIGS. 5-5) The center point of the tilting link device and the direction of the rotation axis must coincide with the height of the center point of the rotating joints on the lower side of the tilting link device and the direction of the rotation axis. This is because if the tilting links are tilted sideways, tilting occurs.

As shown in FIG. 5-B, another method of further strengthening the frame structure for tilting is as follows. As shown in FIG. 5-B, separately installed on the lower side extended frame (FIG. 5-2) 5-2) of each of the above link devices (Fig. 5-2), and similar small-sized link devices (Fig. 5- 6), it is possible to reinforce the structural strength of the lower side frame (FIG. 5-2) extended to the front side without making the space for boarding the car significantly narrower. The inner space of the similar small link devices (Figs. 5-6) has an advantage that it can be used effectively as a space for installing tilting angle adjusting devices according to the steering angle of the steering wheel.

As shown in FIG. 6, based on the operation principle of the tilting car frame, more specifically, the lower side frame (FIG. 6-2) is first formed into a T shape, 6-7) and small link devices (FIGS. 6-8) similar to those of the tilting link devices (FIGS. 6-7) are installed, the front tilting tilting car 6-9 having one front wheel and two rear wheels, You can make two rear wheels and one rear wheel tilting car (6-10).

As shown in FIG. 7, the lower side frame (FIG. 7-2) is formed in a '+' shape, and each of the above link devices (FIGS. 7-7) and small link devices (Figs. 7-8), it is possible to make a diamond tilting car (Fig. 7-11) made up of one front wheel, one rear wheel, and two side wheels.

As shown in FIG. 8, the lower side frame (FIG. 8-2) is formed into a letter shape, and each of the above link devices (FIG. 8-7) and small link devices (Fig. 8-8), as shown in Fig. 8-12, it is possible to make a rectangular tilting car of another frame composed of a rectangular four-wheel tilting car, a front wheel, a rear wheel and two side wheels.

And Figure 9) show a more detailed front, side, top, and perspective views of the overall frame of the three-wheeled tilting car.

As shown in FIG. 10, if the wheels are installed in association with the links on both sides of the linking devices for tilting (FIGS. 3-3), the right- 3-B), when the tilting car is tilted inward of the turning radius, the slope (a) of the outer wheel with respect to the ground is smaller than the slope (b) with the ground of the inner wheel.

As shown in Fig. 11, if the wheels are installed in association with the links on both sides of the linking devices for tilting (Figs. 3-3), the reverse trapezoidal link 3-C), when the tilting car is tilted inward of the turning radius, the slope (a) of the outer wheel with respect to the ground is larger than the slope (b) of the inner wheel with the turning radius.

However, when the tilting car is cornering, it is advantageous that the inclination (b) of the wheel inside the turning radius to the ground is smaller than the inclination (a) of the wheel outside the turning radius.

This is because when the cornering is carried out, the moving distance of the outer wheel becomes longer than the moving distance of the inner wheel of the turning radius.

And the smaller the slope (b) of the inner wheel of the turning radius to the ground is, the more the tilting car is inclined to the inside of the turning radius.

Therefore, mounting the wheels in conjunction with the links on both sides of the device (Fig. 3-C) of the reverse trapezoidal link (Fig. 3-3) is very beneficial in cornering.

In order to mount the wheels in conjunction with the links on both sides of the reverse trapezoidal link (FIG. 3-C) apparatus (FIGS. 3-3), as shown in FIG. 12, 12-14) and the wheels are provided on the auxiliary link device (Figs. 12-14), the cornering can be performed more effectively , The inclination (b) of the wheel inside the turning radius with the ground can be made smaller than the inclination (a) of the turning radius with the ground of the outside wheel.

In this case, as shown in FIG. 12-D, the left and right auxiliary link devices (FIGS. 12-13) are inclined so that the lower side is extended outward when viewed from the front, 14 can make the tilting car more inclined toward the inside of the turning radius when cornering, if the upper side is made to spread outward so that the left and right form a reverse trapezoidal link device. At this time, the angle at which the auxiliary link device (FIG. 12-14) leans outwardly of the reverse trapezoidal link device is very advantageous because it coincides with the camber angle theory of the car wheel for smooth rotation.

And, when the tilting car tilts when cornering, it starts to get out of the cornering, and when it returns to the straight line position, install a shocked shock absorber with spring (Figure 12-15) so that it can easily return to the straight line position.

13-13), in order to supplement the functions of the auxiliary link devices on both sides of the reverse trapezoidal link device (Figs. 12-13, 12-14), the lower frame (Fig. 13-2) Another auxiliary link device (Figs. 13-16) can be installed.

As shown in Fig. 14, when the wheels are connected to the outside of the auxiliary link devices (Figs. 12-14) on both sides of the reverse trapezoidal link device, when the car is tilted and the wheels are tilted together when cornering, (Figs. 14-17) are also inclined. At this time, the axes of both wheels (Figs. 14-17) are tilted downwardly, due to the effect, the wheel inside the turning radius goes down slightly, and the wheel outside the turning radius goes up slightly, 14-18). &Lt; / RTI >

In practice, however, both wheels must be grounded to the ground, so that the wheels outside the radius of rotation slightly raised above the ground will fall back to the ground by the height difference shown in Figs. 14-18). As a result, due to the effect of the inverted trapezoidal link device, the tilting car, which has slipped much into the turning radius, is slightly raised again outside the turning radius due to the effect of the tilted wheel shafts (Figs. 14-17) do.

To solve this problem, as shown in Fig. 15, the wheels are not disposed outside the auxiliary link devices (Figs. 12-14) on both sides of the inverted trapezoidal link device, and conversely, 14), and then the wheel axle (Figs. 14-17) is connected to the wheel from the auxiliary link device (Fig. 12-14).

16), when both wheels are tilted while cornering, the wheel outside the turning radius is grounded to lift the tilting car, while the wheel inside the turning radius is grounded, The tilting car is pulled down.

As a result, a phenomenon opposite to the phenomenon described in the above-described Fig. 14 occurs, and a tilting car that has tilted a lot inside the turning radius due to the effect of the reverse trapezoidal linking device, Therefore, the tilting effect is further increased since the tilting is slightly inclined toward the inside of the turning radius.

As shown in FIG. 17, the length of the auxiliary link devices on both sides of the reverse trapezoidal link device (FIGS. 15-14) is increased and the 'long auxiliary link device' 17-19), and then connect the wheel to this 'long auxiliary link device' (FIGS. 17-19). 17-20), and using the space created here as an engine room, the frame design of a tilting car of a rear-wheel drive tilting car or a reverse tilting wheel of the all-wheel drive A very advantageous point will arise.

As shown in FIG. 18, the 'U' -shaped connecting device (FIGS. 18-21) for connecting the wheels without using a method of increasing the length of the auxiliary link devices (FIGS. 15-14) on both sides of the reverse trapezoidal link device, The wheels are disposed directly below the auxiliary link devices (Figs. 15-14) on both sides of the reverse trapezoidal link device. 17-20), and the space created here is used as an engine room, the frame of the tilting car of the rear wheel drive of the three-wheeled rear-wheel drive or the reverse wheel of the all-wheel drive of the rear- In the case of design, there is a very good advantage.

And since the frame itself is connected to many revolving joints, the tilting car can easily swing from side to side in a stopped state. This condition is very uncomfortable when the passenger gets on and off.

Therefore, unlike ordinary automobiles, it is necessary to provide a separate brake device on the frame, which can keep the left and right shakes of the tilting car stationary in the stopped state.

In order to solve the above problem, as shown in Fig. 19, a 'side brake for fixing the tilting' is made.

19-22) formed with threads on one side is provided horizontally on the link (Fig. 19-2) on both sides of the tilting link device. The worm gears (FIGS. 19-23), which are meshed with the threads of the threaded rods (FIGS. 19-22) and are cut at one end face, are installed so as to be rotatable in the "worm gear axial links" (FIGS. 19-24). A worm gear rotation limiter (FIG. 19-25) is installed on one side of the 'worm gear axis link' (FIGS. 19-24). A suitable gap (Fig. 19-a) is made between the worm gear rotation limiting device (Fig. 19-25) and the cut end of the worm gear (Fig. 19-23). This makes it easier for the worm gear to rotate slightly with the threads of the floating rod (Figures 19-22). After the worm gears (Figs. 19-23) are engaged, the worm gear (Figs. 19-23) can no longer rotate due to the influence of the 'worm gear rotation restriction device' 19-22) can no longer move left or right. As a result, the links on both side surfaces of the tilting link device (Fig. 19-2) are also prevented from moving, so that the lateral movement of the tilting car can be fixed.

19-24) are connected to another link device (Figs. 19-29) using a cable (Figs. 19-26). 19-29) are connected to a "tilting fixed side brake handle" (Figs. 19-28). 19-24) are held in a normally pulled state by a spring (Figs. 19-27), so that worm gears (Figs. 19-23) and threaded rods (Figs. 19-22) I do not make it. 19-26) is pulled up as a result of which the spring (Figs. 19-27) is stretched and the worm gear (Figs. 19-23) are engaged with threaded bars (Figs. 19-22), so that the lateral movement of the tilting car can be fixed. The rotary shaft of the 'tilting and fixing side brake handle' (FIGS. 19 to 28) is provided with a button which is normally stopped, such as is used for a side brake handle of a general automobile, and moves only when it is tightly pulled or pushed by hand.

As shown in FIG. 20, if a hydraulic device having hydraulic oil (FIG. 20-30) is installed in the middle of the link device (FIGS. 20-29), it is possible to easily operate the tilting fixed side brake do.

As shown in FIG. 21, a 'rotor shaft' (FIG. 21-31) is set above the lower frame (FIG. 3-2) and a rotor (FIG. 21-33) or the inverted triangular link device (Fig. 21-34) or the lower circular link device (Fig. 21-35), in which the rotating joints are removed from the rotor (Figs. 21-32) The number of revolving joints for tilting can be greatly reduced, so that a more robust frame for tilting can be produced.

21-33) or the inverted triangular link device (Figs. 21-33), in which the rotational joints of similar resemblance to each other, which are the same in inclination and different in height from each other, 34 or the lower link mechanism (Figs. 21-35) can be used, but the height of the 'rotor shaft' must be made the same to prevent mutual twisting.

22) is a diagram comparing technical differences between 'p67b eternity' and the present design scheme.

'p67b eternity' is a tilting device that does not use a geometric tilting structure but simply tilts the body using a rotating joint. Therefore, in comparison with the present design, when the tilting rotary joint connected to the lower side frame is weak against the external impact and especially when the tilting is performed, the heavy engine can not be tilted, Is narrow, there is a possibility of being inverted by the centrifugal force at a rapid curved road of high-speed traveling.

23) was developed in 1995 after the publication of the 'center-of-gravity mobile vehicle' using the trapezoidal link device by the present inventor, the 'f300 life-jet' of the German company Benz, which first appeared at the Frankfurt Motor Show in 1997, This is a comparison of technical differences between tiles.

Instead of using an inverted trapezoidal link device as a tilting device, a rectangular link device is used. As described above, in order to overcome the disadvantage that the upper and lower sides are not inclined when the rectangular link device is inclined, a secondary connection link device is formed in the lower side frame. And I connected the wheels to this auxiliary connection device so that the wheels were inclined together.

However, when compared to the present design using the historical multicolored link device, the square link device can make the car slant, but the center of gravity of the car from the contact of the wheel outside the turning radius to the ground, I can not make it far.

This can be seen, for example, in the steering system of a typical car to be the difference between the square-link device used before and the common-arm drive using the now used trapezoidal link.

24) shows a comparison between the tilting car frame of the past in 2006 and the present tilting car frame. In the past frame, when connecting the body frame of the vehicle body with the reverse trapezoid tilting apparatus, only the upper side link of the reverse trapezoid tilting apparatus and the body frame of the vehicle body were connected. Therefore, the homework to solve the disadvantage that the lower frame and the rotating joint for tilting are vulnerable to external impact remained.

This is because the body frame of the vehicle body and the trapezoidal link device must intersect at right angles and the geometric movement of the reverse trapezoidal link device is complicated unlike the square or rectangle and the equilateral triangle or the isosceles triangle. It was also very difficult to combine the body frame of the body frame and the trapezoidal link device by using the bearings so that the tilting angles between the body frame and the trapezoidal link devices were matched so that the torsional phenomenon would not occur.

However, as shown in FIG. 5-A and FIG. 5-B, the lower side frame (FIG. 5-2) is elongated forward and then a plurality of separate rotation joints 5-5), or similar small link devices (FIGS. 5-6) are combined, but the tilting angles between the left and right sides are made to coincide without twisting, overcoming the problems of the past.

Modern cities have many problems.

One of the major problems is traffic accidents, parking problems, and serious air pollution due to the increase in passenger cars.

And the climate change of warming due to the excessive use of petroleum fuel, as well as the high oil prices, has long been a serious problem. Still, the number of passenger cars is still approaching 90% even during commute times. Therefore, it is very urgent to develop an ultra-compact car that is as small as a conventional four-wheeled vehicle.

From this point of view, a tilting car that can solve the biggest problem of a super small car is very important.

Fuel is so small and narrow that it can be a solution to parking and traffic problems, but motorcycles can not be used by ordinary citizens when they are snowy or rainy because they can not cover the lid as a whole.

However, since the tilting car does not collapse even when stopped, it can cover the lid as a whole, so it can be used all weather regardless of the weather.

And because the tilting function makes it narrower than a motorcycle, it is safe not only in the cornering, but also in the cornering, it is more comfortable than the ordinary passenger car. And it is well suited as a frame for electric vehicles because of its light weight, which has the mileage problem due to the charging capacity of the battery.

The compact tilting car can solve the urban pollution problem, solve the traffic jam and parking problems at the same time, and it can play a big role in solving the problem of global warming while reducing the liquor cost with the excellent fuel efficiency.

It will also make a great contribution to the development of the electric car industry.

However, as shown in Fig. 3-B, since the center of gravity of the automobile is close to the contact point between the wheel and the ground outside the turning radius, because it tilts to the inside of the turning radius while being pushed outward of the turning radius, , There is a disadvantage in that the resistance of the car against inversion of the turning radius to the outside by the centrifugal force does not increase much, which is disadvantageous for high-speed urgent cornering.

Therefore, in order to overcome the disadvantage of the above-mentioned orthogonal trapezoidal link, as shown in FIG. 3-C, an inverse trapezoidal link (a trapezoid whose upper side length is longer than the lower side length) is made and then tilted to the inside of the turning radius It can be seen that the body of the car (Fig. 3-4) is inclined and the link at the upper side (Fig. 3-1) is inclined obliquely to be perpendicular to the direction of gravity, which is oblique.

The advantage of this inverted trapezoidal link is that the tilting car is moved outwardly of the radius of rotation by centrifugal force, as it makes the center of gravity of the car away from the wheel-to- It is very resistant to overturning.

However, when actually making a tilting car, as shown in Fig. 4), the link devices of the quadrangle, the normal trapezoid, the inverted trapezoid, or the inverted triangle are mounted on the lower frame (Fig. 3-2) And a plurality of installations are performed.

In order to solve this problem, as shown in FIG. 5-A, the lower side frame (FIG. 5-2) is elongated forward and then a plurality of separate rotary joints (FIGS. 5-5) . When connecting the body frame (Figs. 5-4), a plurality of revolute joints (Fig. 5B) on the upper link (Fig. 5-1) and the elongated lower side frame 5 - A), when the body frame (FIG. 4-4) is simultaneously connected, as shown in FIG. 5-A, in the event of continuous external impact from the ground of the off- And the rotating joints can be protected easily.

Another method for further strengthening the frame connection structure for tilting is as shown in Fig. 5-B, in which a plurality of separate rotation joints (Fig. 5- (b)) provided on the lower- 5) are provided with similar small link devices (Figs. 5-6) having different angles and the same angles as the links on both sides of the above respective link devices (Fig. 5-2) It is possible to reinforce the structural strength of the lower side extended frame (FIG. 5B) without making the space considerably narrower. The inner space of the similar small link devices (Figs. 5-6) has an advantage that it can be used effectively as a space for installing tilting angle adjusting devices according to the steering angle of the steering wheel.

As shown in FIG. 6, based on the operation principle of the tilting car frame, more specifically, the lower side frame (FIG. 6-2) is first formed into a T shape, 6-7) and small link devices (FIGS. 6-8) resembling those of the link devices (FIGS. 6-7), a front three wheel tilting car 6-9 having one front wheel and two rear wheels, You can make a reverse tilting car (6-10) with one dog and one rear wheel.

At this time, as shown in FIG. 12-D, the left and right auxiliary link devices (FIGS. 12-13) are tilted so that the lower side is extended outward, and the auxiliary link devices , Making the top side outward so that the left and right forms the shape of the inverted trapezoidal link device, when the cornering is performed, the tilting car can be inclined more inside the turning radius. At this time, the angle at which the auxiliary link device (FIG. 12-14) leans outwardly of the reverse trapezoidal link device is very advantageous because it coincides with the camber angle theory of the car wheel for smooth rotation.

To solve this problem, as shown in Fig. 15, the wheels are not disposed outside the auxiliary link devices (Figs. 12-14) on both sides of the inverted trapezoidal link device, and conversely, -14), and then the wheel axle is connected to the wheel from the auxiliary link device (Figs. 12-14).

As a result, a phenomenon opposite to the phenomenon described in the above-described FIG. 14 occurs, and the tilting car, which is inclined to the inside of the turning radius due to the effect of the reverse trapezoidal link device, The tilting effect becomes larger, and the overall tilting effect becomes larger.

19-22) formed with threads on one side is provided horizontally on the link (Fig. 19-2) on both sides of the tilting link device. The worm gears (FIGS. 19-23), which are meshed with the threads of the threaded rods (FIGS. 19-22) and are cut at one end face, are installed so as to be rotatable in the "worm gear axial links" (FIGS. 19-24). A worm gear rotation limiter (FIG. 19-25) is installed on one side of the 'worm gear axis link' (FIGS. 19-24). A suitable gap (Fig. 19-a) is made between the worm gear rotation limiting device (Fig. 19-25) and the cut end of the worm gear (Fig. 19-23). This makes it easier for the worm gear (Figures 19-23) to rotate slightly with the threads of the floating rod (Figures 19-22). After the worm gears (Figs. 19-23) are engaged, the worm gear (Figs. 19-23) can no longer rotate due to the influence of the 'worm gear rotation restriction device' 19-22) can no longer move left or right. As a result, the links on both side surfaces of the tilting link device (Fig. 19-2) are also prevented from moving, so that the lateral movement of the tilting car can be fixed.

21-33) or the inverted triangular link device (Figs. 21-33), in which the rotational joints of similar resemblance to each other, which are the same in inclination and different in height from each other, 34) or the lower link mechanism (Figs. 21-35) can be used in addition, but the height of the 'rotor shaft' must be made equal to prevent mutual twisting.

'p67b eternity' is a tilting device that does not use a geometric tilting structure but simply tilts the body using a rotating joint. Therefore, in comparison with the present design, the rotating joint for connecting the lower frame is weak against the external impact, and particularly when the tilting is performed, the heavy engine can not be tilted, Is narrow, there is a possibility of being inverted by the centrifugal force at a rapid curved road of high-speed traveling.

However, since the body frame of the vehicle body and the trapezoidal link device must intersect at right angles and the geometrical movement trajectory of the inverted trapezoidal link device is complicated unlike the square or rectangle and the equilateral triangle or the isosceles triangle, the body frame of the vehicle body and the trapezoidal link device It was very difficult to connect the body frame of the vehicle body and the trapezoidal link device once more by using the bearing so that mutual tilting angles were matched so that mutual twisting phenomenon would not occur.
