Embodiment
For understanding the utility model better, below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, 2, a kind of push rod braking device of truck, comprises braking bottom board 1 and brake shoe, and braking bottom board is circular discs, and its one end is provided with cylindrical sleeves, and the other end is provided with hinged seat; Brake shoe comprises left shoe plate 2, the right shoe plate 3 of semicircular arc, the outer circumferential face of left and right shoe plate installs brake strip 4, brake strip is circular arc, the outer circumferential face of left and right shoe plate installs two panels brake strip respectively, one end of left and right shoe plate and hinged seat are hinged by rest pin 5, the other end is connected by extension spring 6, the other end of brake shoe and connecting rod phase configuration.
As in Figure 3-5, connecting rod comprises wobble crank 11, left connecting rod and right connecting rod, and the inner side end center of wobble crank is provided with couple axle 10, couple axle and cylindrical sleeves phase configuration, and the interior edge face of wobble crank and the exterior edge face of cylindrical sleeves abut against; Left and right connecting rod is symmetrically set in the two ends of wobble crank, left and right connecting rod respectively with left and right shoe plate phase configuration; Inwardly have groove 7 in the middle part of the termination of left shoe plate 2 and right shoe plate 3 the other end, on the biside plate of groove 7, symmetry has in the first through hole 8, first through hole 8 and is installed on the first wear-resisting shaft 9.
Wobble crank 11 is kidney-shaped block structure, and its two ends all inwardly have curve bath 12, and the opening of the curve bath at two ends extends along the two ends top center of wobble crank to both sides respectively; On the biside plate of curve bath, symmetry has the second through hole 13, and its installed inside has the second wear-resisting shaft 14.
Left connecting rod comprises left track bar 15 and left connecting plate 17, right connecting rod comprises right track bar 16 and right connecting plate 18, left and right track bar is the rectangular block that both sides inwardly have arc groove, the arc groove of track bar both sides respectively with the first wear-resisting shaft 9 and the second wear-resisting shaft 14 phase configuration; Left connecting plate 17 and right connecting plate 18 are two ends symmetry to have the kidney-shaped of two third through-holes 19 dull and stereotyped, two third through-holes respectively with termination, the outside phase configuration of the first wear-resisting shaft and the second wear-resisting shaft.
