The specific embodiment

Embodiment below in conjunction with in the accompanying drawing is further described the utility model.

Among Fig. 1～Fig. 6, comprise drawing head 1, damper assembly 2, backing plate 21, pad pipe 22, oil damping dash pot 23, buffer gasket 24, back guiding 25, leading to 26, sleeve 27, parallels 28, component contact 3, win 31 in succession, heart-shaped plate 32, stripe board 33, connect pull head 34, bolt 35, oil jacket 36, parking brake 4, handle 41, handle 42, retaining pipe 43, stage clip 44, handle bar 45, gas strut 46, little tooth plate 47, big tooth plate 48, handle case 49, backguy 5, buffer rack 6, dust boot 7 etc.

As shown in Figure 1, the utility model is a kind of trailer brake gear, comprises damper assembly 2, parking brake 4 and connects above-mentioned two-part component contact 3.

As shown in Figure 2, damper assembly comprises sleeve 27 and is engaged in the oil damping dash pot 23 of the compressible release in the sleeve 27.The front end of sleeve 27 is welded with parallels 28, and in drawing head 1, drawing head 1 is connected on the tractor truck through dowel fixes; Oil damping dash pot 23 is fixed in the buffer rack 6, and the rear end of oil damping dash pot 23 is welded on the pad pipe 22, and pad pipe 22 upper end vertical weldings are connected to backing plate 21, and in buffer rack 6, buffer rack 6 is connected on the trailer backing plate 21 by dowel fixes.Be provided with the dust boot 7 that is enclosed within outside the sleeve 27 between drawing head 1 and the buffer rack 6.The back guiding 25 that play the guiding role to sleeve 27 and leading to 26 is installed in the buffer rack 6, and sleeve 27 is slidingly fitted in back guiding 25 and leading in 26.

Like Fig. 3, shown in Figure 4, component contact 3 comprises being hinged on through bolt 35 wins 31 in succession in the buffer rack 6, and bolt 35 is provided with oil jacket 36 between buffer rack 6.Oil jacket 36 is enclosed within on the bolt 35, wins 31 in succession through oil jacket 36 rotations.31 the end of winning in succession is resisted against the rear end of sleeve 27, and the end of sleeve 27 also has been provided with the buffer gasket 24 of buffer action.Win in succession 31 the other end through stripe board 33 with connect pull head 34 and link to each other, stripe board 33 and win in succession and be provided with heart-shaped plate 32 between 31, heart-shaped plate 32 can play buffer action.Connect pull head 34 and link to each other with the brake of trailer, when component contact 3 rotates, connect 5 pairs of trailers of pull head 34 pulling backguys and brake through backguy 5.

Like Fig. 5, shown in Figure 6; Parking brake 4 comprises the handle case 49 that is installed on the bolt 35; The big tooth plate 48 that is fixed on the bolt 35 is installed in the handle case 49, is provided with gas strut 46 between the end of big tooth plate 48 and handle case 49, the two ends of gas strut 46 are hinged through bearing pin.The little tooth plate 47 that is meshed with big tooth plate 48 is installed in the handle case 49, and little tooth plate 47 meshes through teeth with big tooth plate 48.One end of handle case 49 is fixed with and the 31 retaining pipes 43 that match of winning in succession; The other end of handle case 49 is fixed with handle 42; Handle bar 45 is installed in the handle 42; The outer end of handle bar 45 is equipped with handle 41, between handle 41 and the handle bar 45 stage clip 44 is installed, and the inner of handle bar 45 is resisted against on the little tooth plate 47.

The working process of the utility model is following: when tractor truck slowed down or brake, the trailer of back was because inertia still travels forward, and this moment, trailer produced pressure to the damper assembly in the brake gear 2; With 23 compressions of oil damping dash pot, because the two ends of damper assembly 2 are separately fixed on drawing head 1 and the buffer rack 6, so damper assembly 2 slides in buffer rack 6; Be compressed in the process at oil damping dash pot 23, can slowly produce elasticity, make its compression speed more and more slower; Simultaneously, because component contact 3 is fixed on the

buffer rack

6,31 sleeve 27 rear ends that are resisted against in the damper assembly 2 of winning in succession on the component contact 3; So when damper assembly 2 is compressed, sleeve 27 transfixions in the damper assembly 2, and travel forward owing to advancing of trailer drives buffer rack 6; Make that component contact 3 begins to rotate around

bolt

35,4 the rotation of starting to stop of the rotating band of component contact 3 connects pull head 34 pulling backguys 5 simultaneously and begins brake; Parking brake 4 is big tooth plate 48 and little tooth plate 47 engagement rotations when rotating, and big tooth plate 48 is with 46 compressions of gas strut, when brake is accomplished; Gas strut 46 is compressed with big tooth plate 48 in alignment; Produce the dead point, let parking brake 3 no longer rotate, make trailer remain on braking state.When traction is restarted, brake gear has been produced external force, parking brake 4 is under locking state; As long as receive the external force effect, the dead point of gas strut 46 will be destroyed, and the pressure of 27 pairs of component contacts 3 of sleeve disappears simultaneously; Let parking brake 4 revert to original state, removed braking state.

Parking brake 4 also can be used for hand-operated brake.When hand-operated brake, pull-up parking brake 4, parking brake 4 rotates around bolt 35, and the retaining pipe 43 on the parking brake 4 props up component contact 3 and drives its rotation, can accomplish brake like this; When needs are removed braking state, only need press handle 41, handle 41 drives little tooth plate 47 through handle bar 45 and rotates, and also and then rotates thereby drive big tooth plate 48 through engagement, and gas strut 46 is opened, and can remove braking state.

The utility model is provided with damper assembly between tractor truck and trailer, when traction is slowed down or brake, produce elasticity through oil damping; Trailer is played buffer action, let trailer slowly slow down or parking, through component contact brake signal is passed to parking brake simultaneously; The rotation of starting to stop through the rotating band of component contact; Produce the dead point when gas strut is opened to maximum it is fixed, spur the backguy brake simultaneously trailer is checked, so trailer can not produce destructive effect to tractor truck; In addition, parking brake can be used for hand-operated brake.The utility model clear in structure, principle of work is simple, and is easy to use.
