The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, be a kind of goods train vehicle of prior art friction spring formula energy disperser, it comprises a square box 1, be provided with the friction pair of connecting element and moving member composition at an end of casing 1, described friction pair concrete structure can be: be symmetrically arranged with fixedly swash plate 4, two movable tapered wedges 5 of the moving plate of two external fixation plates 2, two 3, two successively from the two side of casing to the center, at last, in the inboard of two movable tapered wedges 5, just the center is provided with a central movable voussoir 6.Wherein, external fixation plate 2 and fixedly swash plate 4 be fixed on the casing, moving plate 3, movable tapered wedges 5 and central movable voussoir 6 are movable, like this, under external force, moving plate 3 just can with external fixation plate 2 and fixedly swash plate 4 fricting movements take place, movable tapered wedges 5 just can with fixing swash plate 4 generation fricting movements.5 motions of central movable voussoir 6 promotion activity tapered wedges.
Be provided with the spring pair in casing 1 inside, described spring pair comprises supporting seat 7, restoring spring 8, central spring group 9, angle spring 10, angle spring perch 11.After assembling, supporting seat 7 upper ends contact naturally with two moving plate 3, two movable tapered wedges 5.Be connected with restoring spring 8 between the top of supporting seat 7 and the central movable voussoir 6.The center of supporting seat 7 lower ends is supported with a group switching centre spring assembly 9, central spring group 9 is one deck coil spring, or forms by inside and outside two-layer coil spring is sheathed.Be provided with four angle springs 10 at the Si Jiaochu of box house, angle spring 10 also is a coil spring, and angle spring 10 can directly contact with supporting seat 7, also can add 11 support and connection of angle spring perch between angle spring 10 and supporting seat 7.After each spring assembly installed, central spring group 9, angle spring perch 11 1 ends contacted naturally with supporting seat 7 (or angle spring perch 11), and the other end contacts with bottom half.When external force imposed on the friction pair, moving plate 3 and movable tapered wedges 5 just promoted supporting seat 7, and supporting seat 7 each spring of recompression are realized energy snubber.
As Fig. 2, shown in Figure 3, improve in order to guarantee energy-absorbing efficient, the utility model changes mono-spring pair into compound elasticity pair on the basis of said structure, mainly carried out the improvement of following several respects:
One, the central spring group is changed into by interior, in, the sheathed spring assembly that forms 12 of outer three layers of spring.
Two, at the center of central spring group 12, or the center of each angle spring 10, have at least center, a place to be equipped with elastic support 13, that is to say, can only wear an elastic support 13 at the center of central spring group 12; Perhaps only wear an elastic support 13 at the center of some angles spring 10; Perhaps wear an elastic support 13 respectively at the center of four angle springs 10; Perhaps all be equipped with simultaneously elastic support 13 at the center of central spring group 12 and the center of each angle spring 10.
One end of elastic support 13 contacts with supporting seat 7 (elastic support in the spring of angle and angle spring perch 11), and the other end contacts with the bottom of casing.Elastic support 13 is made for nonmetallic elastomeric material, and shape mostly is cylindricality, or is similar to cylindricality, and other shapes with supporting capacity are also passable.
Three, with supporting seat steel spring can only be installed thereunder in view of energy disperser before, and the utility model supporting seat can thereunder need to install simultaneously steel spring and post, therefore the utility model supporting seat 14 is made into structure as shown in Figure 4, the center, lower end of supporting seat 14 is made as the form of outstanding two-stage step axle 15, two steps of step axle adapt to the radial dimension of central spring group 12 and elastic support 13 respectively, so that support central spring group 12 and elastic support 13.In addition, the length of step axle 15 is than energy disperser is short before, so that reserve the space that elastic support 13 is installed.
