Detailed description of the invention
For being more fully understood that this utility model, below in conjunction with drawings and Examples, the utility model will be further described。
As Figure 1-4, the tight-holding type brake unit of a kind of truck, including back-plate 1, brake-shoe and braked wheel 5, back-plate is oval plate, and its one end is provided with circular hole 26, and its other end is provided with hinged seat；One end of brake-shoe and hinged seat are hinged, its other end and link gear phase configuration, the inner peripheral surface phase configuration of the outer peripheral face of braked wheel and brake-shoe, link gear includes driving axle 7, left driving arm 8 and right driving arm 9, and left and right driving arm is symmetrically set in the both sides driving axle。
Brake-shoe includes shoe plate and brake strip 4, shoe plate includes left shoe plate 2 and right shoe plate 3, left and right shoe plate is the laminated structure of semicircular arc, the opening of left and right shoe plate is oppositely arranged, its one end is all had hinge hole 23 and is hinged by shoe shaft 24 and hinged seat, its other end is connected by return spring 6, " U " type groove 22 is inwardly had in the middle part of the termination of the left and right shoe plate other end, on the biside plate of " U " type groove, symmetry has through hole 25, connection axle 16 it is installed in through hole, the termination, outside connecting axle is provided with split pin, and split pin is connected with the termination of return spring；Brake strip is arc plate, and the inner peripheral surface of left and right shoe plate is installed on two pieces of brake strips respectively, utilizes friction plate intrados and braked wheel 5 phase frictional damping。
Driving axle is the cylindrical structure that an end head is provided with " S " type projection 10, and " S " type projection two ends are symmetrically arranged left and right wing, and left and right wing is the arc wing that two radiuss of turn are incremented by, and its end face outside center is provided with locating shaft 11；Left and right sliding chute rod is one end and is provided with arc opening groove 12 other end and is provided with the structure of connecting hole 13, the outer side edges of arc opening groove is provided with hole 14, location, the arc opening groove of left and right driving arm respectively with left and right wing phase configuration, and be hinged by locating shaft, the other end of left and right sliding chute rod is hinged with being connected axle。
