Abstract

The invention relates to a four-way joint assembly of an automobile brake. The four-way joint assembly comprises a four-way joint body and a four-way joint nozzle; and a vacuum pip joint mounting hole is formed on the four-way joint body, a vacuum pipe joint penetrates through the vacuum pipe joint mounting hole, is cast and fixed in the vacuum pipe joint mounting hole, and penetrates through a front wall plate of an automobile body, one end of the vacuum pipe joint is connected with a vacuum pipe assembly I, and the other end of the vacuum pipe joint is connected with a vacuum pipe assembly II. In the invention, by additionally arranging a section of the vacuum pipe joint to guarantee the zero-clearance fit between the section of the vacuum pipe joint and the four-way joint body, the plane of the four-way joint assembly is completely laminated with the front wall plate, and the function of the four-way joint assembly for connecting a pipeline is realized favorably under the condition of preventing rain leakage.

Description

A kind of braking cross fitting assembly of automobile
Technical field
The present invention relates to the brake line of automobile system architecture, be specifically related to braking cross fitting structure wherein.
Background technique
Existing automobile brake cross fitting assembly is comprised of cross fitting body, 2 bolts, 4 cross fitting mouths.The cross fitting body is aluminum casting, and 2 bolt rivetings are connected the cross fitting body by bolt on cross fitting with body front panel.In four parallel nipple orifice of cross fitting mouth riveting on the cross fitting body, guarantee and the oil pipe connection sealing.Vacuum tube stretches out body front panel by the through hole on the cross fitting body, links to each other with other part.In this structure, be Spielpassung between the through hole on vacuum tube and the cross fitting body, play seal action by sealing rubber ring, when the gap that assembling herein produces, easily roof leaking in integral vehicular rain test.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of gapless that can guarantee between vacuum tube and the cross fitting body cross fitting assembly structure of avoiding vacuum tube and cross fitting body joint to leak is installed.
Take following technological scheme for solving the problems of the technologies described above the present invention:
A kind of braking cross fitting assembly of automobile, it comprises cross fitting body and cross fitting mouth; Have parallel nipple orifice on the described cross fitting body, cross fitting mouth riveting is connected with brake pipe in nipple orifice; Going back riveting on the described cross fitting body has bolt, and by mounting nuts, the cross fitting assembly is connected with body front panel; It is characterized in that: be parallel to nipple orifice at described cross fitting body and also be provided with the vacuum tube joint mounting hole, other has a vacuum tube joint to be passed by the vacuum tube joint mounting hole, and casting is fixed in the vacuum tube joint mounting hole, described vacuum tube joint passes body front panel, vacuum tube assembly of one termination, No. two vacuum tube assemblies of another termination.
The cross fitting assembly that the present invention proposes has increased by one section vacuum tube joint, this vacuum tube joint is when casting cross fitting body, with the cross fitting body casting together, guarantee that gapless cooperates between this section vacuum tube joint and the cross fitting body, cross fitting assembly plane and front panel are fitted fully, can be good at realizing the function of cross fitting assembly connecting pipeline in the situation that avoid leaking.
Description of drawings
Fig. 1 is the profile schematic diagram of cross fitting assembly of the present invention;
Fig. 2 is the sectional view of cross fitting assembly of the present invention.
Among the figure, 1: nipple orifice 2: cross fitting mouth 3: cross fitting body 4: vacuum tube joint 5: vacuum tube joint mounting hole 6: protruding structure 7: bolt 8: mounting nuts 9: front panel.
Embodiment
Referring to Fig. 1 and Fig. 2, this braking cross fitting assembly comprises cross fitting body 3, cross fitting mouth 2, bolt 7, mounting nuts 8 and vacuum tube joint 4.Have 1, four cross fitting mouth 2 riveting of parallel nipple orifice on the cross fitting body 3 in nipple orifice 1, be connected with brake pipe.Going back riveting on the cross fitting body 3 has bolt, by mounting nuts, the cross fitting assembly is connected with body front panel.Be parallel to nipple orifice 1 at described cross fitting body 3 and also be provided with vacuum tube joint mounting hole 5, other has a vacuum tube joint 4 to be passed by vacuum tube joint mounting hole 5, and casting is fixed in the vacuum tube joint mounting hole 5, described vacuum tube joint 4 passes body front panel 9, vacuum tube assembly of one termination, No. two vacuum tube assemblies of another termination.
Concrete mounting type is: cross fitting mouth 2 and cross fitting body 3 rivetings are connected with brake pipe together.Bolt 7 and cross fitting body 3 rivetings are connected the cross fitting assembly by mounting nuts 7 together with body front panel 9.Vacuum tube joint mounting hole 5 is cast on together on vacuum tube joint 4 and the cross fitting body, the part that vacuum tube joint 4 is arranged in vacuum tube joint mounting hole 5 is processed with a circle protruding structure 6, correspondence is processed with a circle groove at vacuum tube joint mounting hole 5 inwalls, protruding structure 6 embeds in the described groove, prevents that casting from finishing final vacuum pipe joint 4 and coming off from cross fitting body 3.After casting was finished, gapless between cross fitting body 3 and the vacuum tube joint 4 after body front panel 9 installations, can be avoided the phenomenon that leaks herein.
