Definitions
- the present invention is a technique for fundamentally improving the structure of a frame serving as a bogie of a vehicle or the like, changing the vehicle or the like to a fundamentally flexible structure, and realizing safe and flexible use conditions.
- This is a technology that makes it possible to respond to this problem by changing the structure of the divided frame so that the bogie structure of vehicles and the like can be flexibly adapted to various structures and sizes.
- this technology is also a technology that can flexibly cope with the fact that the main parts are connected by a joint whose angle can be adjusted.
- the minimum ground clearance can be set freely at each position of the vehicle body, with a free floor shape and a stable vehicle center of gravity This is a technology that enables settings.
- Passenger vehicles and other vehicles focus on durability and rigid durability, and also lack safety considerations due to design concerns, and have had many problems as a comprehensive vehicle.
- the bogie part of the basic structure of a vehicle is an integral structure with the lower part centered on the floor, so a large amount of metal is required for design, testing, and manufacturing of press dies, including mounting tests for automatic systems. In addition, it took a lot of time to achieve the expected results, but a great deal of effort was required to obtain good performance product experiments.
- frame-type vehicles have the disadvantage that it is difficult to press the frame in one piece, and the cost and weight are inferior to the monocoque type, and it is difficult to cope with the weight distribution when designing the bogie.
- combining the multiple small frames and connecting them with a joint eliminates the above-mentioned disadvantages.
- the degree of freedom in design can be improved and a design with enhanced safety measures can be made. It becomes.
- the joint is a split type, using a hydraulic or electric motor, a gear mechanism, or a cylinder-type power using hydraulic or pneumatic power, control for changing the angle of the joint by program-controlled electronic control technology.
- the angle of the joint of the divided part is controlled by using a rod as a gear, a cylinder, a solenoid, etc.
- the minimum ground clearance can be reduced, and vehicle rollover, slip, idling of wheels on sludge and snowy roads are drastically reduced, and it is used for frame connection.
- the safety can be improved by maintaining a constant safe distance between the ground and the bottom of the vehicle, and the turtle can be prevented from becoming a turtle.
- connection method uses the differential device filed in Japanese Patent Application No. 2001-1 59758 to reduce the rotational speed of the inner and outer tires, and conversely uses the differential device to separately control the rotational speed of the left axle and the tires with wheels.
- the traveling direction of the vehicle is changed by changing the rotation speed using a control device whose speed is program-controlled.
- Equipment that measures the distance between the ground such as infrared rays and millimeter waves will be installed on each part of the vehicle body, and the distance between the ground and each part of the vehicle, etc., will always be measured. This prevents the tortoise state and the contact between the vehicle and the ground.
- a saw-toothed metal plate that can be stretched back and forth and left and right is used.
- the minimum strength required in the vertical direction is also required.
- the angle of the joint at the joint of the frame is adjusted using digital signals according to the previously calculated and predicted procedure, and the vehicle body is moved. At that time, set the material and shape so that the floor material can follow.
- the direction of travel is changed by a digital signal using a steering wheel or bar-shaped controller, and the vehicle is driven in the direction intended by the driver by controlling the front, rear, left and right differentials.
- Improvements in safety, flexibility in the design of the bogie part of the vehicle, drastic cost reductions, and improvement in customer satisfaction as a whole can be easily made so that changes in the body part can be simplified.
- Fig. 1 shows the concept of the connection structure of the angle adjustment type joint of the split type frame.
- Each frame is connected to the joint with a pole-terminal-type connection fitting to form an integrated frame that is connected at any angle. Therefore, if the number of frames is increased, a more flexible shape can be realized, and the ability to take measures against accidents and safety is demonstrated.
- Figure 2 shows the concept of a joint.
- Two rigid arms are used for bearing or sliding performance. Arms that are joined with durable pins, connected to the gear box, and have a structure in which the worm gear that operates by the rotation of the motor and that can be extended and contracted are connected to the gear box in advance are input to the control box. Adjust the total length of the two arms by expanding and contracting according to the program.
- Figure 3 shows the concept of the structure viewed from the top of the split frame. It is a conceptual diagram of the frame which the vertical main frame, the horizontal, the sub-frame, etc. were each connected by the joint and were integrally assembled. By connecting each of these rods with a joint, the degree of freedom in the design of the upper body is greatly increased, and the destruction of the body in the event of a collision can be freely controlled.
- FIG. 4 shows the concept of connecting and holding the wheeled tire to the axle and the transmission of the driving force to the carrier.
- the connection with the vehicle body (symbol 1 2) is basically made using the suspension system filed in Japanese Patent Application No. 2001-376608, and the connection between each axle is made using the differential unit filed in Japanese Patent Application No. 2001-159758.
- FIG. 3 is a conceptual diagram for adjusting a rotation difference between wheels and changing a traveling direction.
- Fig. 5 is a conceptual diagram of floor materials such as vehicles.
- the daruma type is first fastened to one or more freely movable pins on a plate that can freely move vertically and horizontally, and the holes that combine the pins of the plate are processed so that the pins can be moved up and down by increasing the length of the pins. Combine them so that they can respond freely to changes in
- Figure 6 is a conceptual diagram of a passenger car operating the frame so that passengers and occupants can get on and off easily. In this case, the entire passenger compartment of the passenger car is lowered, and there is no step with the ground. This indicates that the technology can be realized by setting the usage pattern and manipulating the frame according to the instructions of the microcomputer.
- a large number of divided frames are connected by a joint whose angle can be changed to form a basic structure of a bogie.
- the axle will be equipped with a large number of split-type small-diameter tires to increase safety, and at the same time, improve the riding comfort of passengers and passengers in vehicles and the like by changing the frame shape and synergistic effects of small-diameter tires.
- FIG. 1 is a conceptual diagram of a split type frame.
- FIG. 2 is a conceptual diagram of a joint.
- FIG. 3 is a conceptual diagram of the entire frame structure.
- FIG. 4 is a conceptual diagram of split connection of a tire.
- FIG. 5 is a conceptual diagram of a floor material.
- FIG. 6 is a conceptual diagram showing a change in a seat position in the case of a passenger car.
