When traveling, the impact on the vehicle body caused by the uneven road surface will be alleviated, and the uneven road surface will be able to run smoothly, so that the ground contact, follow-up performance and contact pressure will not be lost. Therefore, there was no suspension that could be said to be perfect in terms of road surface conditions that changed from one to the other while running, flexible to the occasion, and in particular, to reduce the impact on tires and vehicle bodies from uneven road surfaces. Of course, even on road surfaces with low frictional resistance.

In the conventional front suspension, there is no type that releases or relieves the impact caused by the unevenness received from the front in the front-rear and up-down directions, or that guides it to the rear of the body (received by the belly).

In the conventional front suspension, there is no thing that can reduce the force received from the road surface as the ground pressure to the road surface again.

There was nothing that made it difficult for the impact from the road surface to be transmitted directly to the steering wheel during driving.

Even on slippery uneven road surfaces when driving, there is no catch, yet grounding performance, contact pressure, followability are obtained, tire grip during acceleration and braking is not lost, and even when shocking from the road surface, it is difficult to shake There was no suspension to improve the convergence after jumping.

There was nothing to absorb the force transmitted from the road surface through the rim, spoke, axle, and front fork from the tire at the center of gravity of the vehicle body.

There was no front suspension that absorbs the force transmitted from the tires in the front-rear and up-down directions, and changes the casters to improve the straightness and running stability.

The gear crank was connected to the swing arm, and there was nothing that could ease the shock with the rider's weight and leg strength.

Even a little weight shift made it easier to obtain the force to press against the road surface, and the pressure on the front wheels, the time to press the tire against the road surface were lengthened, and the grip was not improved.

When accelerating or decelerating, the tire grip was not easily lost, and there was nothing that reduced posture change and improved straightness.

There was no structure in which the front fork did not jump, the vehicle body did not jump, and the front and rear tires did not jump during uneven driving.

After jumping, when the vehicle body was in a horizontal orientation at the time of ground contact, there was nothing corresponding to the bending stress and strain ahead of the front fork.

There was nothing that the cushion unit could directly change to the rear arm's pressing force and repulsive force when following unevenness, and the rear wheel's followability and the impact received by the rear wheel.

There was nothing that offset the gear crank and pivot part and let the chain pass through the rear arm.

The front fork from the bottom part was an ellipse, the fork was combined into one, and no spring damper was provided in two stages.

None of the front forks with strong rigidity (in the corners, rectangles, and ellipses) shocks applied to the front wheels were buffered by the front forks and the steering support part in the front and rear and up and down directions.

While running, there was nothing that cushioned the front / rear / up / down impacts on the rear wheels.

There were no rear wheel drives with left and right W drive shafts, W universal joints, biofuel turbo engines, and human-powered turbo units (W compressors, W turbines). There was nothing that made engine sound by human power.

The structure of the rear suspension was divided into a bi-joint structure, (Rhino), (Lower, Rhino), and there was no one that could be operated individually.

The front and rear suspensions have the same structure as the forelimbs and hind limbs of quadruped animals, dogs, etc., the stabilizer connected to the front fork bottom case, the cushion unit that is laid on the upper frame via the pillow stem and rod from the steering stem core of the bracket Is operated with the triangle lever to release the impact force backward. In addition, the arm bends in the middle substantially horizontally from the front hub, extends to the rear of the vehicle body, and the cushion unit is operated from that point. In addition, the front and rear wheels are of the W wishbone type, and the front wheel rudder uses a leaf spring that can be steered left and right while absorbing or sliding up and down. Furthermore, in order to make the structure of the rear suspension to hold down the rear arm, a cushion unit is placed in the middle of the rear arm, and the head of the cushion unit is pressed from the lower part of the frame that extends below the rear arm with a guided rod or the like. The front fork has an oval or rectangular shape, is solid and strong, and a shock absorber that acts like a pillow is added to the rear of the steering head. Therefore, the caster angle is made variable while the impact from the front of the front wheel is avoided by pulling the front wheel and the tire is released upward. Therefore, as can be seen from FIG. 1, the movement of the upper and lower wheels is captured by the cushion unit in front of the front fork, and the forward and backward movement is captured by the rear cushion unit, and the caster angle is made constant or variable. It plays its role by making the front fork into the shape of “ku”.

Stabilizers that connect the impact from the front wheels with the front fork bottom case, from the steering stem core of the bracket part through the pillow ball, the rod, the cushion unit that is laid down on the upper frame is actuated aggressively with the triangle lever and the impact force is rearward in the horizontal direction of the vehicle To escape. Figure 2-3, perspective view.

From the front wheel hub, it is connected to the shock unit at the center of gravity of the car body through the U-arm, universal joint and spline almost horizontally. When turning the rudder, it bends at the universal joint. The rudder is connected to the rudder of the steering wheel via a front fork and a folding plate. The gear crank is connected to the swing arm so as to move with the vertical movement of the rear wheel. FIG.

The impact of the unevenness received from the front is received at the center of the car body by W wishbone. The rear also takes the W wishbone format. The rudder absorbs the vertical motion of the front fork with a leaf spring or slides with a handle stem to fix the left and right motion. FIG.

In order to maintain front fork distortion, front / rear / up / down bending phenomenon, and running stability during braking, the front arm suspension system has two joints, the upper arm (upper arm) is a vertical buffer function, and the forearm (forearm) is It performs the same functions as the dog's forefoot function, such as the forward and backward cushioning function.

The rear arm does not bounce, the body does not bounce, and the rear tire is pressed. For this purpose, the rear suspension spring damper is placed on the rear arm, and the other head is guided from the frame below the rear arm. Connect to the rod to prevent the rear arm from moving up and down. In some cases, links or the like are used in order to increase gradually.

The gear crank, the rear arm, and the pivot portion are separated, and the offset, the internal gear and the planetary gear are applied to the gear crank, and the chain is operated from the outer gear to the sprocket in the rear arm.

The front fork bottom case, inner pipe (fork pipe), and spring damper with coil springs with an elliptical structure are connected by a bottom case that extends above the front wheel. The left and right sides are joined on the table after leaving the minute, the cylindrical pipe is extended from the table to the steering head, and a spring damper is provided to form a W spring and W damper structure.

The steering head and the frame are separated and the steering head can be swung. For this purpose, the rear part of the steering head and the frame are connected horizontally in the horizontal direction with the king pin, and the coil damper is mounted on the top and bottom with the king pin in between. Relieve the shock of Because of the circular motion, the front wheels can absorb and relieve shocks from the vertical direction of the front and rear.

The rear wheel suspension system has a two-joint structure of rhinoceros (thigh) and lower rhinoceros (crus) in order to release the shock applied to the rear tires backwards and upwards. It uses springs, springs and torsion coil springs to absorb the shock, and controls the structure and functions of the dog's hind legs. In addition, as a two-stage type buffer, a spring damper is used in an aggressive manner depending on the application by using the rotation of the rotating part in an auxiliary or independent manner.

It is similar to the claims, but in order to transmit the rotational force obtained from the crank through the drive shaft to the rear wheel through the drive shaft, the rotational force obtained from the crank is transmitted to the W immediately bevel gear, W drive shaft, clogging, Drives the driving force from the W rear axle and W spiral bevel gear to the rear wheels via the W universal joint and W spline. In addition, the W turbocharged engine rotates and produces sound. Or drive it with biofuel.

Since the shock can be absorbed without changing the caster angle, the running stability is maintained. Or, the force transmitted from the tire is absorbed in the front / rear / up / down direction, and the caster is made variable according to the degree and direction of the impact, so that the straightness and running stability can be improved. Optimal casters and trails can be obtained during braking.

There is an advantage that the impact due to the unevenness received from the front wheels is absorbed and mitigated by the impact of the unevenness on the road surface during traveling in the front / rear / up / down direction or in the center of the vehicle body (received by the stomach).

The front wheel can reduce the force received from the road surface as ground pressure to the road surface again. It becomes like this.

The impact from the road surface is not easily transmitted to the steering wheel.

Even on slippery uneven road surfaces, there is no catching, yet grounding performance, contact pressure, follow-up performance, straight running performance, acceleration, braking, good convergence after jumping, hard to shake, tire loss It will be hard to break.

The gear crank is connected to the swing arm, and its legs can also function as a suspension.

It is also possible to improve the pressure and grip of the front wheels by moving some weight. It is easy to obtain the force to press the tire against the road surface, the feeling of pressing is improved sensibly, and the time for pressing the tire against the road surface can be lengthened.

By separating the front wheel suspension system from the upper arm (upper arm) up / down cushioning function and the forearm (forearm) front / rear cushioning function, "the same structure and role as the dog's forelimb" is lightened. Fine-grained tracking is possible.

Reduce bending and bending due to external pressure and impact of front fork.

When traveling, the force received from the rear wheel due to the unevenness is reduced as the force that directly presses the rear arm and suppresses the rear arm, so the jumping of the rear wheel is suppressed and the follow-up performance, contact pressure, and contact performance are improved.

Since the gear crank and pivot part are offset, it is possible to stroke the pedal at a good position, the rear arm installation angle can be installed at an ideal position, and no harm is caused, and the pivot and sprocket are the same position Therefore, it is not necessary to make extra chain slack.

By passing the chain through the rear arm, it also serves as a chain cover and prevents the pants from getting dirty and caught by the sprocket and chain.

In claim 12, the rigidity of the front fork can be increased by making the front fork into an ellipse.

The front fork operates more finely by providing spring dampers in two stages on both the bottom case part of the front fork and the two forks on it.

As the steering head rotates and the front wheels make a circular motion with the king pin as a fulcrum, the shock applied to the front wheels can be absorbed and mitigated up and down and up and down.

By dividing the structure of the rear suspension into a two-joint structure, rhinoceros (thigh), lower and rhinoceros (thighs), it is possible to buffer the front and rear and upper and lower impacts applied to the rear wheels during running. Unleashes the same structure and role as the “dog hind limb”. "

The rear wheel is driven by a W shaft drive, canceling the moment of inertia of the shaft. The turbo unit is W, so that the balance is also improved, the pedal is turned and the engine is turned on and the sound is emitted. The rider will be pleased, the vehicle will be recognized, the pedal will be encouraged, and the fuel supply will also be a turbocharged engine. In addition, depending on the license, it becomes a motorcycle.
