Abstract
The invention relates to a compact centring device installed on a compact buffer. The centring device comprises a centring sleeve, a centring body, a roller, a roller plug and a spindle, wherein the centring sleeve is installed on an installation seat of the buffer and is connected with the roller plug by fastening; the centring body and the spindle are fastened on a buffer system of the buffer; a centring element is installed in the centring body and synchronously rotates with a revolving axle of a revolving mechanism of the buffer. The centring device has simple and reasonable structure. The centring element is arranged inside the centring body, therefore, the centring device is small in volume and convenient to install. Under the action of the roller, after a hook buffer device rotates in the horizontal direction in the presence of external force, the buffer device can restore to the initial state when the external force disappears or diminishes, thus ensuring the centre line of the hook buffer device to be identical with the centre line of the vehicle. The hook buffer device can not further rotate through contact of the limiting surface between the centring sleeve and the centring body, thus preventing accidents due to too large rotation angle.
Description
Technical field
The present invention relates to a kind of rolling stock shock absorber, specifically, relate to a kind of rolling stock close-coupled energy disperser.
Background technology
The close-coupled energy disperser generally comprises buffer system, rubber bearing, aligning gear and mount pad, and wherein buffer system can play the effect that absorbs the longitudinal impact in the vehicle operating process, can improve the traveling comfort in the vehicle operating process effectively; The function of rubber bearing is at vertical direction supporting hook buffering apparatus; Aligning gear can make it recover centering after coupler buffering device rotates in the horizontal direction automatically, and coupler buffering device line of centers and vehicle centre-line are consistent; Whole shock absorber firmly can be installed on the floor underframe for vehicle by mount pad.But, existing aligning gear because centering element is arranged on the outside to middle shell, makes the volume of aligning gear big, inconvenience is installed, thereby make that the volume of close-coupled energy disperser is excessive, in the vehicle operating process, after coupler buffering device rotates in the horizontal direction, because the volume of energy disperser is excessive, when it automatically restores to virgin state, coupler buffering device line of centers and vehicle centre-line are consistent, restorability is poor automatically.
Summary of the invention
The objective of the invention is at the horizontal direction that existing close-coupled energy disperser the exists back the problems referred to above such as restorability is poor automatically, volume is excessive that rotate, provide a kind of simple and reasonable, volume is little, can make shock absorber rotate the back good close-coupled aligning gear of restorability automatically.
Technical scheme of the present invention is: a kind of close-coupled aligning gear, be installed on the close-coupled energy disperser, described aligning gear comprises that centered cover, centered body, roller and roller are stifled, and rotating shaft, described centered cover is installed on the mount pad of energy disperser, and is fastenedly connected with roller is stifled, and centered body and rotating shaft are fastened on the buffer system of energy disperser, centering element is installed in the centered body, and the axis of revolution of centering element and energy disperser swing type mechanism rotates synchronously;
Preferably, be provided with piston between described centering element and the centered body, centering element is installed in the piston;
Preferably, described piston is the piston that has piston abrasion cover, and this piston is provided with two, and described centering element is the dish spring, fills the dish spring in the piston, and dish spring internal sleeve is equipped with pilot bar;
Preferably, described roller housing is contained on the roller shaft, and be arranged on centered body and roller stifled between.
Beneficial effect of the present invention is: the present invention is simple and reasonable, centering element is arranged on the inside of centered body, make the volume of aligning gear little, be convenient to install, and by the effect of roller, after coupler buffering device rotates because of the external force effect in the horizontal direction, when external force disappears or reduces, can make shock absorber return to initial condition, coupler buffering device line of centers and vehicle centre-line are consistent.The present invention can't be further rotated coupler buffering device by the contact of the confined planes between centered cover and the centered body, can prevent because the excessive appearance of angle of rotation is unexpected dangerous.

The specific embodiment
The specific embodiment of the present invention is as follows: as shown in Figures 1 to 3, a kind of close-coupled aligning gear, be installed in the bottom of energy disperser, described aligning gear comprises centered cover 1, centered body 2, roller 4 and roller stifled 3, and rotating shaft 6, centered cover 1 is installed on the mount pad of energy disperser, and is connected by bolted with roller stifled 3, and mount pad and centered cover 1 all do not rotate during the coupler buffering device rotation; Centered body 2 and rotating shaft 6 are fastened on by bolt 10 on the buffer system of energy disperser, and when coupler buffering device horizontally rotated, buffer system can drive rotating shaft 6, centered body 2 and rotate together, and transmit rotating torque by interference fit face A; Two pistons 11 that have piston abrasion cover 9 are installed in the centered body 2, fill dish spring 5 in the piston 11, dish spring 5 rotates synchronously with the axis of revolution of energy disperser swing type mechanism, and dish spring 5 internal sleeve are equipped with pilot bar 8; Can prevent that dish spring 5 from hindering its compression among falling into the gap of piston 11; Roller 4 is sleeved on the roller shaft 7, and is arranged between centered body 2 and the roller stifled 3.
As shown in Figure 4, owing between roller stifled 3 and the centered cover 1 bolted is arranged, when centered cover 1 counter roller stifled 3 relatively rotated, roller 4 rolled along the B of contact surface shown in the figure, and compression is loaded on in-to-in dish spring 5.The contact surface B that consequent masterpiece is used in roller 4 and roller stifled 3 goes up the rotating torque that forms a pair of and direction of rotation; After the external force that forces coupler buffering device to rotate disappeared or reduces, this moment just can make coupler buffering device be returned to initial condition, and coupler buffering device line of centers and vehicle centre-line are consistent.In turning to Fig. 6 ± and during Φ ° position, roller 4 contacts at the circular arc of center of gyration with one section circle centre position on the roller stifled 3, and after this compressive force of dish spring 5 will no longer produce countermoment, and coupler buffering device is in free rotary state at this moment.
As shown in Figure 5, when centered body 2 rotate to ± α ° after, the confined planes C of centered cover 1 and centered body 2 is in contact with one another, coupler buffering device can't be further rotated, and can prevent because the unexpected danger of excessive appearances of the anglec of rotation.
