Detailed description of the invention
See above-mentioned accompanying drawing, a kind of transversal-push type bogie truck integrated brake device, comprises and is with the brake cylinder assembly 1 of brake slack adjuster, main brake beam assembly 2, secondary brake beam assembly 3, two bent levers 4 to be connected push-rod assembly 5 with two, it is characterized in that:
The beam body of described main brake beam assembly 2 and time brake beam assembly 3 is a few shaped sections, and namely main brake beam body 23 and time brake beam body 31 all adopt high strength steel or aluminum alloy clod wash or roll forming;
Described two bent levers 4 by riveting spiral pin symmetrically pin joint at the Liang Tishang of main brake beam assembly 2, and be clipped between main brake beam beam body two panels compound plate;
Described two connect push-rod assembly 5 upper ends respectively with beam body 31 and interior key seat 32 pin joint of secondary brake beam assembly 3.Upper end pin-and-hole 42 pin joint of the two bent levers 4 of connection push-rod assembly 5 lower end respectively with pin joint on main brake beam assembly 2.
See Fig. 2 and Fig. 3, described main brake beam assembly 2 and time brake beam assembly 3 pass through with riveting screw anchor integral by beam body, left brake head and right brake head; Namely main brake beam assembly 2 is integral with riveting screw 22 rivet clasp by left brake head 21, beam body 23 and right brake head 26.Wherein: beam body 23 is provided with installation pin-and-hole, this installation pin-and-hole, built with riveting spiral pin 24, is set with the supporting sleeve 25 of fixed beam body two compound plate spacing outside riveting spiral pin 24; Secondary brake beam assembly 3 is integral with riveting screw 22 rivet clasp by left brake head 21, beam body 31 and right brake head 26; Wherein: beam body 31 is provided with installation pin-and-hole, this installation pin-and-hole, built with riveting spiral pin 33, is set with the interior key seat 32 of fixed beam body two compound plate spacing outside riveting spiral pin 33.
The beam body of main brake beam assembly 2 and time brake beam assembly 3 is all with high strength steel (or aluminum alloy) clod wash or the beam body 23,31 being rolled into a few shaped sections, uses riveting screw 22 rivet clasp integral with left brake head 21 and right brake head 26.Brake head 21 and 26 casts out end slide block, is arranged in the side frame chute of bogie truck for brake beam.Because the Braking position of brake beam changes near brake head by traditional central authorities, particularly secondary brake beam assembly 3, the moment of flexure that brake beam is born greatly reduces, add that again a few font section improves horizontal, the vertical load-carrying capacity of beam body, therefore the more traditional bow break beam of this type brake beam, more comparatively cast the weight reduction of brake beam, and clod wash, rolling mill practice is easy, reliable in quality, production efficiency are high, cost is low.
See Fig. 4 and Fig. 5, bent lever 4 is provided with middle pin-and-hole 41, upper end pin-and-hole 42, lower end pin-and-hole 43.
See Fig. 6, connect push-rod assembly 5 and press-fited by push rod cup before two pieces 51 and stage casing steel pipe 52 and form.In push rod cup 51 pin-and-hole, ball cover 52 is housed.The push rod cup of split is convenient to the forging of high-quality punching block and machinework, and reliability is high.Push rod stage casing adopts steel pipe Compression Stability good, lightweight.
In sum, it is relatively simple that this transversal-push type bogie truck integrated brake device has structure, and brakig force distribution is even, reliable effect, from heavy and light, and low cost and other advantages.
