Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure, said horizontal buffer is used for engine truck, and it mainly constitutes by planker 1, rubber stop 2, connecting panel 3 and compression backing block 4 are installed.
Like Fig. 1, shown in Figure 2, said installation planker 1 one ends are the bigger oblate cylinder 1a of diameter, and it is the less slender cylinder 1b of diameter that planker 1 other end is installed; Said rubber stop 2 is cones of a hollow, and the microcephaly that the slender cylinder 1b of said installation planker 1 inserts rubber stop 2 holds in the 2a, and rubber stop 2 microcephalies hold the end face of 2a to be close to the oblate cylinder 1a that planker 1 is installed; Said connecting panel 3 one sides are used to connect car body; Be welded with annular ring 3a on connecting panel 3 another sides; The stub end 2b of said rubber stop 2 places in the annular ring 3a, and the outer peripheral face of rubber stop 2 stub end 2b is close to the medial surface of annular ring 3a, and the end face of rubber stop 2 stub end 2b is close to connecting panel 3; The center of said connecting panel 3 is provided with mounting hole, and compression backing block 4 fixedly is assemblied in this mounting hole.
As shown in Figure 1, said compression backing block 4 is provided with a suitable stopper section 4a of interior hole shape with rubber stop 2 stub end 2b, and the central fovea of stopper section 4a is provided with and installs the suitable cavity 4b of planker 1 slender cylinder 1b; Said stopper section 4a top sides is along being made as circular arc, said rubber stop 2 microcephalies hold be provided with in the 2a with stopper section 4a top sides along the suitable arcs of recesses groove 2c of shape.When planker 1 bearing load is installed; Rubber stop 2 distortion that is crushed; Rubber stop 2 contacts with the stopper section 4a of compression backing block 4, through graphic circular arc is arranged on 4a top sides edge in stopper section, the rubber stop 2 of distortion can not contacted with sharp keen edge; Thereby rubber stop 2 is played the certain protection effect, effectively prolong its service life.In addition, rubber stop 2 contacts with the stopper section 4a of compression backing block 4 also can avoid installing directly bump compression backing block 4 of planker 1, can prolong their service life and reduce operating noise.
As shown in Figure 1, the thickness of annular ring 3a peristome reduces from inside to outside gradually, and the medial surface of annular ring 3a peristome is a cambered surface of curved transition from inside to outside.When planker 1 bearing load is installed; Be crushed distortion and contact of rubber stop 2 with annular ring 3a; Annular ring 3a peristome is arranged to graphic shape can make the rubber stop 2 of distortion can not contact with sharp keen edge; Thereby rubber stop 2 is played the certain protection effect, further prolong its service life.
As shown in Figure 1, be the more frequent position of load that withstands shocks because the centre of planker 1 oblate cylinder 1a is installed, so among the present invention, the thickness that planker 1 oblate cylinder 1a is installed is less gradually by middle mind-set edge.
Among the present invention, said installation planker 1, connecting panel 3 and compression backing block 4 all adopt metallic material to process, and said rubber stop 2 adopts elastomeric materials to process, and are integral by the vulcanization of rubber of rubber stop 2 is affixed between said installation planker 1, rubber stop 2 and the connecting panel 3.Said compression backing block 4 is fitted in the mounting hole at connecting panel 3 centers with interference fit.
During concrete the application, the present invention is used for the bogie truck of locomotive (like harmonious No. 3 diesel locomotives of EMD), and connecting panel 3, is used between bogie truck and car body, transmitting lateral load through bolted connection on car body.
The present invention has high high low temperature limiting performance; Product is at limit low temperature-40 ℃ following 24h; The limiting performance of testing product, at the pressure of the vertical loading 150KN of product and after keeping 1 minute, breach and unusual bulging phenomenon do not appear in rubber stop 2 parts with the rate of load application of 10mm/min; At room temperature place 24h, survey the limiting performance of product with same condition again; Product is placed on limit high temperature+65 ℃ following 24h, the limiting performance of testing product, at the pressure of the vertical loading 150KN of product and after keeping 1 minute, breach and unusual bulging phenomenon do not appear in rubber part with the rate of load application of 10mm/min.
