Description

The electronic wheel instrument of tearing open of four-head

The utility model relates to the electronic wheel instrument of tearing open of a kind of four-head.

Automotive wheel generally is by four nuts or the nut more than four wheel to be fixed tightly on the axletree, tightens or unclamps a nut, according to varying in size of car, if with spanner dismounting nut, need very big power, and at every turn can only dismounting one, generally need the power more than tens kilograms at least.

In Chinese patent application number is to disclose name in 91228169.3 to be called " tube lifter ", and its structure includes a body, protecgulum, bonnet, first driver element, second driver element, transmission component and align member.During use, earlier the collet head on second driver element being sheathed on wheel goes up on the nut of desire dismounting, to make align member withstand between body and the ground, the application of force makes the rotation of first driver element drive the rotation of second driver element by transmission component, the nut on the wheel can be unscrewed then.In case after the nut that the user will take turns unscrews, will take turns dismantling devices and be reversed end for end, sleeve is changed be placed on first socket part, and rocking bar is installed on second socket part, can apace all nuts be screwed off.The tube lifter of this structure is because for preventing the body rotation, on body, be provided with a location member, nut of every dismounting is all different according to the seat height of nut on wheel, from newly controlling align member, or the length of regulating align member, the ground soft or hard that adds upper support differs, and is uneven, the adjusting of align member is comparatively frequent, uses to seem inconvenient.Moreover, though nut unscrew, if nut or screw rod any one get rusty or between foreign material such as silt are arranged, the capital causes getting loose of nut freely not suitable, will not take turns dismantling devices and turn and just the nut that gets loose can be screwed off, and can only revolve next nut at every turn, still quick inadequately.

In Chinese patent application number is to disclose name in 85202707 to be called " simple and easy wheel nut loader ", its structure includes a motor, big small belt pulley, be connected in the cone belt on the big small belt pulley, main shaft and on the lug nut cover, bearing, striking arm circle cover impulse pin etc., when motor rotates, drive the deceleration belt pulley, make the impulse pin that is fixed on the big belt pulley make circular movement together, after the impulse pin seat moves to and is with striking arm circle cover part to collide, the rotation of big belt pulley is by the effect of impulse pin at this moment, driving striking arm circle cover and main shaft rotates together, make main shaft and wheel ut socket obtain moment of torsion strength, tire is torn or pretend open industry.This kind removing machine is owing to adopt pulley transmission structure, and this heaviness very, and bulky is not easy to operation, once also can only nut of dismounting, be unfavorable for the dismounting of taking turns.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a compact conformation, simply light and handy, easy to use, the dismounting electronic wheel instrument of tearing open of four-head efficiently is provided.

For realizing the purpose of this utility model, the electronic wheel instrument of tearing open of this four-head includes motor, housing, the drive division of housing be provided with automotive wheels on cooresponding several rotating shafts of clamp nut, in rotating shaft, be provided with connect with sleeve pullover, there is a bull to drive the deceleration assembly, is connected between the axle of each rotating shaft and motor.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the electronic constructional drawing of tearing the wheel instrument open of the utility model four-head.

Fig. 2 is the electronic another kind of constructional drawing of tearing the wheel instrument open of the utility model four-head.

Fig. 4 is the constructional drawing that motor connects transmission in Fig. 1 or 2 with retarder.

Fig. 5 is the B-B cutaway view among Fig. 4.

Below in conjunction with accompanying drawing, electronic wheel instrument two embodiment wherein that tear open are described in further detail to the utility model four-head:

As shown in fig. 1, the electronic wheel instrument of tearing open of the utility model four-head comprises motor (1), housing (2), the drive division (4) of housing (2) be provided with automotive wheels on cooresponding four rotating shafts of clamp nut (5), in each rotating shaft (5), be provided with the tetragonal prism that can connect pullover (6) with sleeve, drive deceleration assembly (7) by a bull of being made up of gear, this bull drives deceleration assembly (7) and comprises the retarder (8) in the Handheld Division (3) that is arranged on housing (2) and be arranged on the interior bull gear drive (9) of drive division (4).Specifically, bull gear drive (9) can be to comprise and the fastening driven gear that connects of rotating shaft (5) (10), with be fixed in retarder (8) and go up and driven gear (10) ingear driving gear (14), spool being linked together so just each rotating shaft (5) and motor (1).

As shown in Fig. 2 and Fig. 3, bull gear drive (9) also can be to comprise respectively and the fastening driven gears that connect of four rotating shafts (5) (10), be enclosed within the limit dual gear (11) in one of them rotating shaft (5), the center shaft (12) that is enclosed within drive division (4) go up and with driven gear (10) and limit dual gear (11) ingear center dual gear (13), be arranged on the retarder (8) and limit dual gear (11) ingear driving gear (14).The miniature gears of center dual gear (13) and four driven gears (10) engagement, the pinion on big gear wheel and the limit dual gear (11), and big gear wheel on the limit dual gear (11) and driving gear (14) engagement that is arranged on the retarder (8).The power more suffered than nut of a dismounting owing to four nuts of a dismounting is big four times, adopt dual gear like this, not only play driving action, and can further regulate rotating speed again, be convenient to setting and the adjustment of motor on positional structure, also alleviate the load of motor simultaneously, make to produce to refer to make four-head electronic to tear the wheel instrument open more flexible.

As shown in Figures 4 and 5, retarder (8) comprises two rotating disks (15) that have driving gear (14), on each rotating disk (15), be equipped with three jack-posts (16), correspondence is with three can be around the planetary wheel (17) of jack-post (16) rotation, be provided with in the gear case (19) of retarder (8) and planetary wheel (17) ingear inner gear (20), have in motor (1) rotating shaft one with planetary wheel (17) ingear driven wheel (18), because each rotating disk and its upper planetary gear constitute the one-level transmission system with certain revolution ratio, according to circumstances, can be designed to the speed change of one-level or some grades, jack-post on the rotating disk and the corresponding planetary wheel that is provided with also can be several.Be provided with wear-resisting copper sheathing (21) between output gear (14) and the gear case (19), motor (1) is fixed on the case lid (22) of gear case (19).Such structure design makes retarder be arranged on the Handheld Division, can make the outside maintenance in Handheld Division cylindric, be convenient to hand and arrest operation, and compact conformation, light and handy.

The utility model four-head driven wheel removing tool is than having now owing to having adopted the clamp nut with on the automotive wheels corresponding Four rotating shafts and pullover and bull drive the structure between the axle that the deceleration assembly is connected in each rotating shaft and motor, at the dismounting nut The time, can utilize the relative fixed position of automotive wheels top nut to fix the four-head driven wheel removing tool, when having avoided because of the turn nut The own rotation of four-head driven wheel removing tool that produces once can be finished the disassemble and assemble work of wheel, have use light and handy, convenient, Simple in structure, compact, dismounting is advantage efficiently.
