    A METHOD OF JOINING THE SURBAISSE FLOOR VEHICLE AND THE JOINT SYSTEM
    Technical Field: The present invention relates to a hinge connection method of a vehicle and a corresponding hinge system. More specifically, the invention relates to a new method of connection between the bodies of a low floor vehicle, and the corresponding articulation system, to improve the articulation performance of the vehicle. This invention belongs to the technical field of manufacturing the critical parts of the vehicle.
    Technical background: "The low floor vehicle" is a specific and professional term of the railway vehicle, which refers to the railway vehicle with a distance of less than 40cm between the vehicle and the track. The low floor vehicle is divided into several models based on the percentage of the floor area relative to the body, such as the 70% low floor vehicle, and the 100% low floor vehicle, etc. ; among which, the most difficult in technology is that of 100%. Generally, the low floor vehicle is comprised of two or more vehicle bodies connected by a hinge system. This articulation system between the two bodies of the low-floor vehicle that undergoes the forces, and whose connection security decides the safety factor of the vehicle, is the load piece to connect the funds of the two bodies. The connection structure of the vehicle body is divided into three models: the first articulation model is the ankle ball structure, used in the first vehicles; the second is the large diameter rotating table bearing structure, which ensures the vehicle turn performance; and the third employs the peg structure in which the vehicle bodies connect through the sheath that provides vehicle turn performance.
    Currently, the popular low-floor vehicle articulation device is often installed at both sides of the body connection, adopting the upper and lower articulation coordination method, limiting the movement of the vehicle body through the devices. articulation, to guarantee the minimum radius of curvature capacity. The bottoms of the neighboring bodies of the low floor vehicle more generally employ the fixed hinge hinge device, and the tops of the adjacent bodies use the hinge device of rotation, or the combination of the hinge and the hinge. free articulation. The fixed hinge device at the bottom of the vehicle will limit the horizontal displacement in three directions, allow rotation in three directions, undergo the vertical force of the vehicle, and transmit the most longitudinal force (in the direction of the operation of the vehicle ) and horizontal force; the rotation articulation device at the top of the vehicle will allow the rotation of the neighboring bodies on the vertical axis, provide the longitudinal and horizontal hardness through the rubber component parts, and in collaboration with the fixed hinge device at the bottom , it will support a part of the longitudinal traction of the vehicle, restrict the lateral sliding movement of neighboring bodies, allowing only a relative freedom of shaking between the two neighboring bodies, and meet the urban requirement of the radius of curve , thus with the requirements of the minimum radius of vertical and horizontal curvature. At the top of the neighboring bodies of the vehicle separates the free articulation device from that of rotation according to the requirements. View of the structure of the different rotation joint, the top rotation joint varies depending on the model of the vehicle, and the basic mode often sees install a rotary joint device at the top of the vehicle body to connect the tops bodies, and ensure the stable passage of the horizontal curve and the vertical curve of the low-floor vehicle; the free joint installed at the top is an auxiliary connection system to limit only the lateral sliding movement between the bodies. This system of articulation of the low floor vehicle in combination of these three devices is already widely applied in the current articulation system. However, there are still problems in this popular system, such as the lack of connection reliability, insufficient stability, and unforeseen displacement or leakage, etc., especially the traditional method of hinged fixed hinge prefers that the upper base and the lower base directly connect the metal seal bearing via the central pin, which takes advantage of the central pin to connect the two neighboring bodies through respectively the upper base, the metal seal bearing and the lower base . This method of connection with the central peg structure complicates the fixed hinge structure or lowers the modularization, and requires a large assembly space; in addition, the fixed hinge device always requires regular maintenance, cleaning, and examination of the state of lubrication and movement; the adoption of the method of connection with the structure of the central pin increases the difficulty of assembly, and disassembly of the dormant hinge device, and thus makes any type of maintenance more difficult. As for the current popular rotation joint, which generally adopts the connection of the "V" shaped ankle axis, it is too complicated for the assembly and the corresponding adjustment, and is not rational either. by the analysis of the state of force: therefore the popular traditional articulation system still reserves the problems that influence the normal operation of the vehicle, which reduce the life of the vehicle. It is necessary to continue the corresponding more detailed and precise studies.

    Particular embodiments of the invention
    Here are the detailed descriptions for the technical solution of this invention with the help of diagrams and examples.
    Example I
    Figure 1 illustrates the general principle of an example of the present invention. The invention relates to a system for articulating a vehicle with a low floor and adopting a double articulated connection of the multiple bodies, and the body of the low floor vehicle 1 forms the articulation system via the combination of a fixed hinge 2, of a rotation joint 3 and a free articulation 4. Are the characteristics: the fixed articulation 2 and the articulation of rotation 3 of the articulation system mentioned take as the key piece of articulation the rolling unit metal seal 5, the latter connects respectively the fixed hinge and that of rotation to form the rotary hinge piece.
    In addition, this above-mentioned metal seal bearing divides into a metal joint bearing of the fixed hinge 6 and into a metal joint bearing of the rotary joint 7, the latter 6 connects the two ends of the bottom of the vehicle body. through the connecting piece, and this 7 connects the two ends of the vehicle body top through the rotational connection piece.
    See Fig. 2 and Fig. 3, the metal seal bearing unit 601 of the aforementioned fixed hinge metal seal bearing 6 is covered between the upper attachment base 602 and the lower attachment base 603, and the The metal seal bearing unit is connected with the upper attachment base and the lower attachment base by two connecting pieces 606 of the upper attachment base 602 and the lower attachment base 603 to be able to connect the two neighboring bodies.
    In addition, the metal seal bearing unit 601 includes the outer metal seal sleeve 604, the outer rotation sleeve 605 installed in the outer metal seal sleeve 604, the inner rotation ball 607 installed in the outer rotation sleeve. 605, and the floating resistant sheath 609 installed between the outer metal sheath 604 and the outer rotating sheath 605; it contacts through the spherical surface the inner rotation ball 607 and the outer rotating sleeve 605, the outer rotating sleeve 605 and the floating resistant sleeve 609; the outer metal sleeve 604, the outer rotating sleeve 605, the inner rotation ball 607, and the friction-resistant sleeve 609, all together form in a single complete metal seal bearing unit through the connecting piece 608.

This example abandons traditional lubrication and solid, and adopts the aforementioned method, leaving the friction-resistant sleeve I functioning as the friction-resistant sleeve and also the lubrication.

    In addition, the inner seal ring 704 of the metal seal bearing unit 701 is covered on the central axis 705 of the base 702 via the forced fit sheath, and is fixed via the ring 706 on the central axis 705; the outer seal ring 707 of the metal seal bearing unit 701 connects the spherical side of the inner seal ring 704, the outer seal ring of the metal seal bearing unit 701 respectively contacts the inner ring of the barrel the upper ball 708 and the lower ball sleeve 709 of the V-shaped adjustable connecting rod 703 formed by the upper ball sleeve and the lower ball sleeve to disperse the force of the outer ring 707 of the ball metal seal bearing unit 701 on the upper ball sleeve 708 and the lower ball sleeve 709. The upper ball sleeve 708 and the lower ball sleeve 709 are coupled by the undercab 710; the top ball sleeve 708 has the ring 711, and the bottom ball sleeve 709 uses the convex bench 712 to prevent the outer ring seal from being ejected from the metal seal rolling unit 701.
