Description
Technical field
The utility model is related to automotive field, and in particular to a kind of tyre pressure sensor and valve cock.
Background technology
Realized because the traveling of automobile is the rotation by wheel, and contact of the wheel with ground is to rely on tire
Realize, tire can support vehicle body, buffer foreign impacts, realize the contact with road surface and ensure the driving performance of vehicle.
And the air pressure in tire it is too high when, easily heavy load effect under cause to blow out；When the air pressure in tire is too low,
The deflection increase of wheel, radial-deformation increase so that the friction increase on tire tread and ground, rolling resistance rises, carcass
Internal stress also rise therewith, so as to produce abrasion, accelerate the aging of tire.
Therefore in order to ensure traffic safety, it is necessary to assure the air pressure in tire is in normal range (NR), when the gas in tire
Pressure is too high or too low, and driver is notified in time.
Tire pressure is typically monitored using tyre pressure sensor direct measurement tire pressure, tyre pressure sensor can be arranged on Automobile
On the wheel hub of wheel, as shown in Figure 1.
Tyre pressure sensor includes：Valve cock bar 1, dust cap 2, valve inside 4, locking nut 3 and body 5.
The dust cap 2 of tyre pressure sensor is general to use metal or plastic manufacturing.Due to manufacturing process, lead to
The outside diameter d of normal dust cap 2 is more than the internal diameter D of locking nut 3, as shown in Fig. 2 so not removing the premise of dust cap 2
Under, locking nut 3 can not cross dust cap 2, and realization is screwed with the first screw thread 11 on valve cock bar 1.
For the cooperation of dust cap 2 and valve cock bar 1, according to international standard (ETRTO, European tyre Rim Technical committee
Member meeting) recommendation, have strict screw-down torque code requirement, to ensure that it has certain air-tightness.
Therefore, the general assembly process for recommending valve cock bar 1 and dust cap 2 is completed in tyre pressure sensor manufacturer：
The assembling of dust cap 2 and valve cock bar 1 is complete in clean workshop by professional equipment according to screw-down torque specification
Into so as to ensure that it tightens quality；In addition, in the transportation of valve cock bar 1 (tyre pressure sensor manufacturer to tire pressure
The maquila of sensor and wheel rim), due to there is a protection of dust cap 2, valve inside 4 be not easily susceptible to pollution (dust, greasy dirt,
Foreign matter etc.).
The assembly process of valve cock bar 1 and dust cap 2 is not recommended to be completed in the maquila of tyre pressure sensor and wheel rim,
Its reason is：The maquila of tyre pressure sensor and wheel rim general lack of professional tightening device (equipment in itself with maintaining phase
To costliness), but tightened by manual, on the one hand, it, which tightens quality, to ensure, on the other hand, it tightens the efficiency of operation
Also it is very low.
Therefore the production of tyre pressure sensor and installation process typically use following several ways：
(1) tyre pressure sensor manufacturer (assembling of valve cock bar 1 and valve inside 4->Valve cock bar 1 and dust cap 2
Assembling)-be transferred to-maquila of tyre pressure sensor and wheel rim (assembling of valve cock bar 1 and wheel rim->Dust cap 2 is torn open
Unload->The assembling of valve cock bar 1 and locking nut 3->The assembling of valve cock bar 1 and dust cap 2).
(2) tyre pressure sensor manufacturer (assembling of valve cock bar 1 and valve inside 4->Valve cock bar 1 and dust cap 2
Assembling)-be transferred to-maquila of tyre pressure sensor and wheel rim (dismounting of dust cap 2->The dress of valve cock bar 1 and wheel rim
With->The assembling of valve cock bar 1 and locking nut 3->The assembling of valve cock bar 1 and dust cap 2).
It is suitable with the operation of the assembling of wheel rim and the dismounting of dust cap 2 that above-mentioned (1), (2) kind mode are valve cock bar 1
It is different in sequence, all there is problems with：
(a) dust cap 2 tyre pressure sensor and wheel rim maquila it is secondary tighten when, tighten quality it cannot be guaranteed that；
(b) to during tightening again after dust cap 2 is dismantled, it is likely to result in valve inside 4 and pollutes；
(c) dismounting of unnecessary dust cap 2 and secondary tighten reduce installation effectiveness.
(3) tyre pressure sensor manufacturer (assembling of valve cock bar 1 and valve inside 4)-be transferred to-tyre pressure sensor and wheel rim
Maquila (assembling of valve cock bar 1 and wheel rim->The assembling of valve cock bar 1 and locking nut 3->Valve cock bar 1 and valve
The assembling of mouth cap 2).
Tyre pressure sensor manufacturer so exists without the assembling of valve cock bar 1 and dust cap 2 in (3) kind mode
The maquila of tyre pressure sensor and wheel rim avoids the need for carrying out the dismounting of dust cap 2, although improve to a certain extent
The efficiency of installation, but there is problems with：
(a) dust cap 2 is when the maquila of tyre pressure sensor and wheel rim is tightened, and tightening quality can not ensure；
(b) (the group of tyre pressure sensor manufacturer to tyre pressure sensor and wheel rim during the transport and storage of valve cock bar 1
Fill factory), due to having lacked the protection of dust cap 2, valve inside 4 is easily contaminated (dust, greasy dirt, foreign matter etc.).
The content of the invention
For problems of the prior art, problem to be solved in the utility model is to provide a kind of tyre pressure sensor,
By the external diameter that the internal diameter of locking nut is set greater than to dust cap so that valve cock bar is assembled to wheel hub with dust cap
On operation without being completed under conditions of dismounting dust cap, so that the quality of tightening of dust cap can either be ensured, and energy
Enough ensure that valve inside is not contaminated, while installation effectiveness will not be reduced because of unnecessary operation.
The utility model provide a kind of tyre pressure sensor, including body, the valve cock bar being connected with body, dust cap with
And locking nut, dust cap is fixedly connected on the end of valve cock bar, and locking nut is sheathed on outside valve cock bar, locking screw
Female internal diameter is more than the external diameter of dust cap.
Further, be provided with outside valve cock bar with locking nut coordinate the first screw thread and with dust cap coordinate
Second screw thread.
Further, the wall thickness of dust cap is less than the difference of the external diameter of the first screw thread and the external diameter of the second screw thread.
Further, the wall thickness of dust cap is less than 1mm.
The utility model also provides a kind of valve cock, including valve cock bar, dust cap and locking nut, dust cap
The end of valve cock bar is fixedly connected on, locking nut is sheathed on outside valve cock bar, it is characterised in that the internal diameter of locking nut is big
In the external diameter of dust cap.
Compared with prior art, the utility model is provided tyre pressure sensor and valve cock, have the advantages that：It is logical
Cross the external diameter that the internal diameter of locking nut is set greater than to dust cap so that valve cock bar is assembled on wheel hub with dust cap
Operation without dismounting dust cap under conditions of complete, so that the quality of tightening of dust cap can either be ensured, again can
Ensure that valve inside is not contaminated, while installation effectiveness will not be reduced because of unnecessary operation.
Brief description of the drawings
