(assemble method)
Next, with reference to Fig. 5, to eye joint 2, lifting bolt 3, head side washer 4, threaded portion side washer 5 and cap 6
Assemble method illustrate.Fig. 5 is the exploded perspective view for indicating air brake hose nipple sub-assembly 1.
As shown in Figure 1, Figure 2, Figure 5, in the axle portion 32 of lifting bolt 3 head is sequentially inserted into from 31 side of the head of lifting bolt 3
The annulus 61 of portion side washer 4, the annular portion 23 of eye joint 2, threaded portion side washer 5 and cap 6 makes mutually to combine closely.
It is assembled into air brake hose nipple sub-assembly 1 as a result,.At this point, multiple screening glass 631 of cap 6, which become inclined surface 631a, contacts screw thread
Portion 34 and the state slightly expanded.
(installation method)
Next, with reference to Fig. 6 A~Fig. 6 D, to air brake hose nipple sub-assembly 1 to be installed on to the installation side of caliper 110
Method illustrates.In addition, also being illustrated to the method for connecting air-brake coupling hose 100 in air brake hose nipple sub-assembly 1.
Air brake hose nipple sub-assembly 1 is equipped on automobile by the way that the threaded portion 34 of lifting bolt 3 to be fastened on (for diagram)
Caliper 110 internal thread part 111 and connect with caliper 110.
As shown in Figure 6A, if the part that the slave cap 6 of the threaded portion 34 of lifting bolt 3 exposes is anchored on caliper 110
Internal thread part 111, then the front end of multiple screening glass 631 of cap 6 contacted with the joint surface 112 of caliper 110.If further fastening
Lifting bolt 3, then as shown in Figure 6B, multiple screening glass 631 are further expanded.After lifting bolt 3 is fastened certain degree, such as scheme
Shown in 6C, the handle portion 62b of the handle part 62 of cap 6 is held, the long side direction by cap 6 along handle part 62 is extracted.
Finally, as shown in Figure 6 D, by the fastening of lifting bolt 3 until the annular portion 23 of threaded portion side washer 5 and eye joint 2
Lower surface and the joint surface 112 of caliper 110 combine closely.At this point, the annular portion 23 of head side washer 4 and eye joint 2
Upper surface combine closely.The space being formed in as a result, between groove portion 33a and the inner peripheral surface of annular portion 23 is sealed.
After the insertion section 21a that hose transition 21 is inserted into the end of air-brake coupling hose 100, riveting is carried out to hose transition 21
It connects, the end of fixed air-brake coupling hose 100.In addition, air-brake coupling hose 100 can also be installed on by air brake hose nipple sub-assembly 1
It connect, can also combine air brake hose nipple after being connect with hose transition 21 with hose transition 21 after caliper 110
Part 1 is installed on caliper 110.
(flow path of fluid)
Next, to being flowed between air-brake coupling hose 100 and caliper 110 via air brake hose nipple sub-assembly 1
The flow path of fluid illustrates.
As shown in Fig. 2, being formed with space between the annulus 23 of eye joint 2 and the groove portion 33a of lifting bolt 3.Shape
At between groove portion 33a and the inner peripheral surface of annular portion 23 space and set on the connection cave 2a and lifting bolt 3 of eye joint 2
Through hole 3b connections.
Therefore, it is formed via the eye joint 2 and lifting bolt 3 of air brake hose nipple sub-assembly 1 and to air-brake coupling hose 100
And the flow path of the fluid of caliper 110.
(functions and effects of embodiment)
According to the present embodiment, functions and effects below are played.
(1) cap 6 is assemblied in the threaded portion 34 of lifting bolt 3, so as to by eye joint 2 and lifting bolt 3 and
4,5 integration of washer, the assembling work of air-brake coupling hose 100 become easy.
(2) the surface 5a of the annulus 61 of cap 6 and the opposite side of the annular portion 23 of the eye joint 2 of threaded portion side washer 5
It contacts and protects surface 5a, therefore even if eye joint 2 and lifting bolt 3 and washer 5 are transported in the state of integration
It is defeated, it can also inhibit washer 5 impaired.Therefore, multiple air brake hose nipple sub-assemblies 1 are not packed independently also can be by it
Be bulked in a chest and transported.
(3) the substantially whole of the threaded portion 34 of lifting bolt 3 is covered by the protection portion 63 of cap 6, therefore can in transport
Protect the threaded portion 34 of lifting bolt 3 is equal not to be damaged.In addition, protection portion 63 because of gap by distinguishing discretely along the week of axle portion 32
It is constituted to multiple screening glass 631 of configuration, to which when fastening lifting bolt 3, multiple screening glass 631 are easy expansion, can make
The terminal operation of lifting bolt 3 simplifies.
(4) when cap 6 to be assemblied in the threaded portion 34 of lifting bolt 3, protection portion 63 of the screening glass 631 because being formed in cap 6
Multiple screening glass 631 inner surface inclined surface 631a and slightly expand, therefore further fastening lifting bolt 3 when, it is more
The interval of a screening glass 631 further becomes larger.Therefore cap 6 will not interfere terminal operation.
(5) after the interim fastening of lifting bolt 3, the screw thread from lifting bolt 3 can be easy using handle part 62
Unload cap 6 in portion 34.Workability is improved as a result,.
(6) threaded portion 34 of lifting bolt 3 is crimped by the protrusion 61b for being formed in the inner peripheral surface of the annulus 61 of cap 6, therefore
In transport etc., cap 6 is difficult to fall off.In addition, being not necessarily to the thread for making washer on one side and lifting bolt as described in Patent Document 1
Thread is screwed, and washer is made to insert lifting bolt on one side, thus can easily by eye joint 2 and lifting bolt 3 with
And 4,5 integration of washer.
