Abstract
The utility model provides a braking system's whelk that crosses is tied, includes the bolt body, the bolt body divide into head and pole portion from top to bottom, the lateral wall axial of pole portion is provided with the oil groove of leading of V -arrangement to be provided with the screw thread. This is neotype crosses the whelk and ties and lead the oil groove through the V -arrangement of lateral wall setting and accomplish the function of leading oil, simple structure, and easily processing is little to the intensity effect of bolt, not fragile, can avoid taking place the probability that leaks, guarantees vehicle braking effect, reduces the traffic accident odds.
Description
Technical field
The utility model relates to a kind of component of brake system of car, specifically, is a kind of oil draining bolt excessively of braking system.
Background technique
In the braking system of passenger car chassis, connect brake hard tube and be connected by brake hose assemblies between brake caliper; Joint in brake hose assemblies is crossed oil draining bolt by one and is connected with red copper gasket seal, and brake fluid flows through Brake pipe joint, crosses oil draining bolt, arrives clamp.
As shown in Figure 1, current oil draining bolt central coaxial of crossing arranges oil guiding hole, and arranges the intercommunicating pore be connected with oil guiding hole at sidewall.It is all that the first cold-heading of needs becomes base shape that this mistake oil draining bolt adds man-hour, then holes; Except axial drilling, also need the radial bore of at least one, this reduces the intensity of this kind of bolt, when the oil pressure of brake system oil is higher or when bolt tightening torque is larger, easy deformed damaged, so that cause brake oil to leak, make brake failure, cause traffic accident.
Model utility content
The deficiency that the utility model exists for above-mentioned prior art, what devise a kind of braking system crosses oil draining bolt.
The oil draining bolt excessively of braking system of the present utility model, comprise bolt body, described bolt body is divided into head and bar portion up and down, and the side-wall shaft in described bar portion to the oil guide slot being provided with V-arrangement, and is provided with screw thread.
Preferably, the top in described bar portion is provided with flange, and the top of described oil guide slot extends to flange place, and bottom extends to the bottom in bar portion, and described screw thread is arranged on the bottom in bar portion, and the width of screw thread shared by bar portion is less than the length of oil guide slot.
The beneficial effects of the utility model are: what this was novel crosses oil draining bolt completes Oil Guide function by the V-arrangement oil guide slot that sidewall is arranged, structure is simple, be easy to processing, little to the intensity effect of bolt, not fragile, the probability occurring to leak can be avoided, ensure car brakeing effect, reduce traffic accident odds.
The bar portion on oil guide slot top arranges flange, and coaxality when flange ensure that workpiece is assembled improve the sealability that oil draining bolt fixes rear oil duct.Width shared by screw thread is less than the length of oil guide slot, and make bar portion, place, oil guide slot top not have screw thread, sidewall is smooth, and bar portion diameter dimension is less than flange and screw thread place size, ensures that brake oil can pass through V-type oil guide slot smoothly, arrives brake calipers.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of prior art.
Accompanying drawing 2 is the structural representation crossing oil draining bolt of the present utility model.
Embodiment
The oil draining bolt excessively of this braking system, as shown in Figure 2, comprise bolt body, bolt body is divided into head 1 and bar portion 2 up and down.The side-wall shaft in bar portion 2 to the oil guide slot 3 being provided with V-arrangement, and is provided with screw thread 4.
Brake pipe joint passed through oil draining bolt and was connected with brake caliper, and the braking fluid in brake hose assemblies is entered by Brake pipe joint and has been in the oil guide slot 3 of oil draining bolt, and finally flow in brake caliper, and driving brake sheet moves.
This crosses oil draining bolt processing also comparatively easily, directly uses cold upsetting forming die, makes the sidewall pier mold forming of bolt shank go out the oil guide slot 3 of V-arrangement, and then tapping.Eliminate the operation of boring, ensure that the intensity of bolt, also improve manufacturing efficiency.
The top in bar portion 2 is provided with flange 5, and the top of oil guide slot 3 extends to flange 5 place, and bottom extends to the bottom in bar portion 2.
Screw thread 4 is arranged on the bottom in bar portion 2, the width of screw thread 4 shared by bar portion 2 is less than the length of oil guide slot 3, bar portion, place, oil guide slot 3 top 2 is made not have screw thread 4, sidewall is smooth and diameter dimension is less than flange and screw thread, because this position is connected with Brake pipe joint, smooth oil guide slot 3 edge ensure that the circulate of brake fluid.
