Type and simplification description, rather than indicate or imply that the device of indication or element must have specific orientation, with specific orientation
Construction and operating, therefore it is not intended that to restriction of the present utility model.Additionally, term " first ", " second ", " the 3rd " are only used
In description purpose, and it is not intended that indicating or hint relative importance.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", " being connected ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or integratedly
Connect；Can be to be mechanically connected or electrically connect；Can be to be joined directly together it is also possible to be indirectly connected to by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Concrete meaning in this utility model for the language.
Please refer to Fig. 1, the pneumatic impact spanner of the tire for vehicles that the present embodiment provides, including air motor, (in figure is not marked
Note), motor includes motor drive shaft 1, stator 3 and rotor 2, and motor drive shaft 1 is fixedly connected with rotor 2, and stator 3 is fixed on a shell 10
On.
The pneumatic impact spanner of tire for vehicles also includes: by planetary gear z2, sun gear z1, internal gear (in figure is unmarked) and row
One planetary reducer (in figure is unmarked) of carrier 5 composition, the front end of motor drive shaft 1 is fixedly connected with sun mark wheel z1, interior
Gear is included rear portion z3 and is all engaged with anterior z4, planetary gear z2 and rear portion z3 and anterior z4；Rear portion z3 can in shell 10 edge
Slide axially.
The pneumatic impact spanner of tire for vehicles also includes being meshed group by the front end half-clutch device 8 castellated with one first of anterior z4
Become first clutch (in figure is unmarked), and be made up of one second castellated half-clutch device 7 and one the 3rd castellated half-clutch device 6
Second clutch (in figure is unmarked), the rear end of the 3rd castellated half-clutch device 6 is fixedly connected with planet carrier 5.
The pneumatic impact spanner of tire for vehicles also includes a wrench shaft 9, and (in figure is not marked to open up grooved hole in wrench shaft 9 backwards
Note), slotted eye is provided with a compression spring 11, and one end of compression spring 11 is connected to slotted eye bottom, and the other end is connected to the second dental inlay
The front end of the half-clutch device of formula 7 abuts against, wrench shaft 9 be set in the first castellated half-clutch device 8 and castellated with first half from
Clutch 8 spline connection.
The pneumatic impact spanner of tire for vehicles also includes being arranged on the driving end 12 of wrench shaft 9 front end.
Wherein, the first castellated half-clutch device 8 is notched teeth, the second castellated half-clutch device 7 and the 3rd castellated half
Clutch 6 is trapezoidal tooth.
The pneumatic impact spanner of the tire for vehicles of the present embodiment adopts two sets of clutches, can make respectively to pull in zero load and after loading
Handss axle automatically obtains high and low two kinds of rotating speeds.Its principle is as follows:
When unloaded (dismounting), the rotary motion of motor drive shaft 1 reaches planet carrier 5, then after planetary reducer
Catch the 3rd castellated half-clutch device 6 and the second castellated half-clutch device 7 reaches wrench shaft 9 and makes its revolution at a high speed.Now due to
First castellated half-clutch device 8 and axle 9 spline connection, therefore its rotating speed are more than the rotating speed of internal gear 4, and therefore first castellated half
Clutch 8 just skids along the inclined-plane of notched teeth.
When loading (installation), the 3rd castellated half-clutch device 6 and the second castellated half-clutch device 7 overload are skidded, motor
Axle 1 must move and just reach internal gear 4 via planetary gear speed-reduction, and reached motion by the first castellated half-clutch device 8 and pull
Handss axle 9 is so as to low speed turns round.Now because internal gear 4 is driving link, the first castellated half-clutch device 8 is that driven member (return by zero load
Contrast when turning) therefore by the vertical transmitting torque of notched teeth, and continue to force the 3rd castellated half-clutch device 6 and
Two castellated half-clutch device 7 overloads are skidded.
So, by the simple structure of such a, can in unloaded and adjust automatically rotating speed in the case of loading two kinds, and
Obtain different moments of torsion to adapt to the needs mounting and dismounting.It does not need install sensor, thus reliability is higher.
Preferably, the second castellated half-clutch device 7 and the 3rd castellated half-clutch device 6 are antiparallelogram tooth.
Preferably, driving end is removably attached on wrench shaft.So just can be changed according to the nut of different model
Use suitable driving end, therefore versatility is higher.
The place that in this specification, other do not describe in detail is prior art, therefore repeats no more.
Last it is noted that various embodiments above is only in order to illustrating the technical solution of the utility model, rather than it is limited
System；Although being described in detail to this utility model with reference to foregoing embodiments, those of ordinary skill in the art should
Understand: it still can be modified to the technical scheme described in foregoing embodiments, or to wherein some or all of
Technical characteristic carries out equivalent；And these modifications or replacement, do not make the essence of appropriate technical solution depart from this practicality new
The scope of type each embodiment technical scheme.
