Description
Technical Field
The utility model relates to the field of automobiles, specifically be an automobile-used air brake pipe assembly.
Background
The existing domestic air brake pipe assembly is formed by pre-riveting an air brake metal pipe and a clamping sleeve to assemble a nut and then screwing and connecting the pre-riveted nut and the clamping sleeve type joint body. The clamping sleeve sealing structure has relatively strict assembly requirements and is slightly inclined, so that air leakage is easy to occur, and once leakage occurs, the brake failure is caused to cause a driving accident; in order to avoid assembly leakage, the whole car factory is sealed with glue during assembly, so that additional cost and assembly efficiency are increased.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide an automobile-used air brake pipe assembly.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model relates to an automobile-used air brake pipe assembly, it is protruding including the conical surface joint body, nut, air brake tubular metal resonator and sphere, air brake tubular metal resonator end department shaping is a spherical surface of spherical seal protruding, the fixed cover of air brake tubular metal resonator outer loop department is equipped with the nut, air brake tubular metal resonator outer loop department is equipped with the conical surface joint body, the conical surface joint body is equipped with the external screw thread with air brake tubular metal resonator contact inner wall, pass through nut and external screw thread threaded connection between air brake tubular metal resonator and the conical surface joint body.
As an optimized technical scheme of the utility model, the bellied extrados of spherical surface of air brake metal pipe laminates with the interior conical surface of the conical surface joint body.
As an optimized technical scheme of the utility model, the spherical surface of air brake metal tube is protruding to be extruded by forming die.
As an optimized technical scheme of the utility model, the conical surface joint body is formed by machine tooling, conical surface joint body conical surface angle increases 46 degrees on cutting ferrule formula joint body conical surface angle basis.
The utility model discloses the beneficial effect who reaches is: the utility model relates to an automobile-used air brake pipe assembly, air brake steel pipe and joint body coupling have reduced the mode that prior art used the cutting ferrule to connect, extrude mutually through sphere and conical surface and realize sealed, have the leakproofness and dismantle convenient characteristics well, and good leakproofness does benefit to the normal work of guaranteeing automobile brake system, guarantees the safety that the vehicle travel, the cutting ferrule is cancelled to the scheme, and reduce cost increases economic benefits, and certain host computer factory vehicle rolls off the production line pressurize qualification rate and promotes to 99.9% and market operation back by 88.9% and wins the recognition of customer's height.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention.
In the drawings:
fig. 1 is a schematic view of the overall structure of the present invention.
In the figure: 1. a conical surface joint body; 2. a nut; 3. a pneumatically actuated metal tube; 4. the spherical surface is convex.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Examples
As shown in fig. 1, the utility model relates to an automobile-used air brake pipe assembly, connect body 1, nut 2, air brake tubular metal resonator 3 and sphere arch 4 including the conical surface, 3 end departments shaping of air brake tubular metal resonator are spherical arch 4 of a spherical seal, the fixed cover of 3 outer ring canals departments of air brake tubular metal resonator is equipped with nut 2, 3 outer ring canals departments of air brake tubular metal resonator are equipped with conical surface joint body 1, conical surface joint body 1 is equipped with the external screw thread with 3 contact inner walls of air brake tubular metal resonator, pass through nut 2 and external screw thread threaded connection between the body 1 with conical surface joint body 3 of air brake tubular metal resonator.
Wherein, the outer cambered surface of the spherical surface bulge 4 of the air braking metal pipe 3 is attached to the inner conical surface of the conical surface joint body 1.
Wherein, the spherical bulge 4 of the air braking metal tube 3 is formed by extrusion of a forming die.
The conical surface joint body 1 is formed by machining, and the conical surface angle of the conical surface joint body 1 is increased by 46 degrees on the basis of the conical surface angle of the ferrule type joint body, so that the attaching area of the conical surface joint body and the spherical protrusion 4 is increased, and air leakage caused by incorrect assembly angle is avoided.
In the pipeline assembling process, the tightening torque that the operator was applyed turns into the pretightning force of pressing from both sides tight sphere and conical surface, under the effect of installation pretightning force, sphere surface and conical surface laminate mutually, the compression of each other forms the contact surface gradually, adopt above-mentioned technical scheme, the mode that prior art used the cutting ferrule to connect has been reduced, cancellation cutting ferrule reduce cost increases economic benefits, it realizes sealedly to extrude mutually through sphere and conical surface, the good convenient characteristics of dismantlement of leakproofness has, good leakproofness does benefit to the normal work of guaranteeing automobile brake system, the safety that the assurance vehicle travel.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
