Accompanying drawing explanation
Accompanying drawing 1-2 is the structural representation of the specific embodiment of the invention.
Accompanying drawing 3 is specific embodiment of the invention guiding and locking gear schematic diagram.
Accompanying drawing 4 is the structural representation of specific embodiment of the invention round bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Fig. 1 to 2, a kind of Tension compression conversion type rubber buffer, this energy disperser comprises rubber draft gear 1, draw ring 3 and pull bar 4, and the both sides of rubber draft gear 1 are provided with the inhibiting device for controller buffer stroke; The rear and front end of rubber draft gear 1 is respectively provided with a fixing adapter plate, and rear adapter plate 2 is fixed on draw ring 3, and the pull rod shaft of pull bar 4 is sleeved in the centre hole of rubber draft gear 1 and front mounting plate 5.
In order to realize the control to draft gear travel, above-mentioned inhibiting device comprise the round bar 6 that is arranged on rubber draft gear 1 both sides and be arranged on round bar 6 two ends from plate, this round bar 6 is for having the body of rod of multi-stage stairs structure, the less step in round bar 6 two ends is used for location, and middle larger step is used for transmission of pressure; Before be arranged between rubber draft gear 1 and front mounting plate 5 from plate 8, after install between rubber draft gear 1 and rear adapter plate 2 from plate 7.
One end of above-mentioned round bar 6 is fixed by bolt 9 from plate 8 and front mounting plate 5 through front, is fixed after the other end passes from plate 7 and rear adapter plate 2 by bolt 10.
In order to make energy disperser be controlled accurately, the intermediate step of above-mentioned round bar 6 is identical with the stroke energy disperser compression condition apart from the front distance from plate 8, identical with the stroke energy disperser stretching operating mode from the distance of plate 7 after the intermediate step distance of round bar 6.
In order to prevent pull bar 4 from rotating, front mounting plate 5 is provided with anti-rotation boss 11.
As shown in Figure 3, pull rod shaft is set with fiber axle sleeve 14, effectively can prevents the wearing and tearing of pull rod shaft, this fiber axle sleeve 14 is between pull rod shaft and front mounting plate 5.
Moving forward and backward for the ease of pull bar, the end of above-mentioned pull rod shaft is connected with guide piece, and the end of pull rod shaft can be moved in the centre hole of draw ring 3 with guide piece; In order to prevent the connection between pull rod shaft and guide piece from loosening, between pull rod shaft and guide piece, be provided with locking gear.
As shown in Figure 3, above-mentioned guide piece is outside is circular nut 12, and above-mentioned locking gear is straight pin 13, in order to the centre hole preventing the nut 12 of back end of tie rod from shifting out draw ring 3, nut 12 is connected with the end screw thread of pull rod shaft, and the length of nut 12 is greater than stroke when energy disperser stretches; Squeezing into straight pin after nut 12 fix in position prevents nut 12 from loosening.
Above-mentioned guide piece can also arrange threaded orienting lug and annulus etc. for inside; The parts that above-mentioned locking device can also adopt other to have fixation replace, such as screw, screw rod etc.
Above-mentioned rubber draft gear 1 is the integrative-structure sulfided by intermetallic metal plate and two ends rubber block, and rubber block both sides excise to avoid rubber block structure to expand afterwards and surrounding structure is interfered.
Principle of work: under compression condition, first have pull bar 4 compress before from plate 8, front from plate 8 compressing rubber energy disperser 1, by after transfer the pressure to rear adapter plate 2 from plate 7.Wherein, assuming that the stroke of compression condition lower bumper is x, the intermediate step of round bar 6 also etc. is all x apart from the front distance from plate 8, controls the stroke of compression condition lower bumper with this.
Under stretching operating mode, the nut of pull bar 4 rear end pull transfer is given after from plate 7 thus compressing rubber energy disperser 1, from plate 8 and front mounting plate 5 before rubber draft gear 1 compresses, then by the round bar 6 of both sides, power is passed on rear adapter plate 2.Wherein, assuming that the stroke of stretching operating mode lower bumper is y, the intermediate step of round bar 6 apart from after also etc. be all y from the distance of plate 7, carry out the stroke of restrained stretching operating mode lower bumper with this.
