Abstract

The utility model relates to a repairing tool for automobile tire, in particular to a labor-saving disassemble and assemble device for disassembling and assembling the nut of the automobile tire. The utility model comprises a spanner, a housing and a socket, cycloidal pin-wheel reducer is fixed in the housing, an input port of the cycloidal pin-wheel reducer is movably connected with the spanner, and an output end of the cycloidal pin-wheel reducer is fixedly connected with the socket. Owing to making use of the cycloidal pin-wheel reducer to decelerate, the utility model has the advantages of simple structure, large transmission ratio, steady transmission and small noise.

Description

The motor tire replacer

(1) technical field under

The utility model relates to a kind of motor tire recovery equipment, particularly a kind of laborsaving attaching/detaching apparatus of dismounting automotive tyre nut.

(2) background technology

At present, dismounting automobile lug nut, adopt two kinds of instruments usually: a kind of is common socket wrench, and the moment of this spanner is limited, requires great effort very much during use.Another kind is special electric or pneumatic removing machine, and the volume of this removing machine is bigger, and weight is heavier, is not suitable for carrying with car, changes tire on the way for automobile and brings difficulty.More existing patented technologies are 962201804 Chinese patent " laborsaving wrench for dismounting " as the patent No., are to utilize the epicyclic reduction gear structure, reach the labour-saving purpose.As the patent No. is 01265853 Chinese patent " with vehicle truck tyre screw replacer ", is to utilize gear reduction, reaches the labour-saving purpose.But the equal more complicated of the structure of above-mentioned patent, the labor-saving effect is not obvious, goes wrong easily during use, brings unnecessary trouble to the user.

(3) summary of the invention

The utility model is in order to overcome above deficiency, provide a kind of simple in structure, the labor-saving effect good, motor tire wrench for dismounting easy to use.

The utility model is realized by following measure:

The utility model discloses a kind of motor tire replacer, include spanner, shell and sleeve, its special feature is: shell internal fixation one cycloidal-pin wheel retarder, and the input end of cycloidal-pin wheel retarder and spanner flexibly connect, and the mouth of cycloidal-pin wheel retarder is captiveed joint with sleeve.

Replacer of the present utility model, it further improves and is, and sleeve flexibly connects a quill, and quill has a sleeve pipe that is fixed together with shell outward, and there is a fixed arm end of sleeve pipe.

Replacer of the present utility model in order to adapt to different motor tires, has many covers and the suitable quill of different nuts.

Speed reduction gearing of the present utility model has utilized the cycloidal-pin wheel retarder.The cycloidal-pin wheel input shaft of speed reducer drives two accentric cams staggered relatively, and two cams drive two clutch plates respectively, makes clutch plate do the eccentric motion.There is n tooth in the outside of clutch plate, studs with n+1 drum-type column in the shell, because the column number is Duoed one than the clutch plate number of gears, thereby works as input shaft and rotates a week, and clutch plate only rotates n/week.Clutch plate connects by column type and links to each other with output shaft, therefore, when input shaft rotates a week, in output shaft rotation n/week, realizes n: 1 deceleration effect.

Motor tire replacer of the present utility model owing to utilize the cycloidal-pin wheel retarder to slow down, thereby has simple in structurely, and transmitting ratio is big, stable drive, the advantage that noise is little.

(4) description of drawings

Accompanying drawing is a structural representation of the present utility model

Among the figure, 1 handle, 2 shells, 3 sleeves, 4 sleeve pipes, 5 quills, 6 fixed arms

(5) specific embodiment

As shown be a kind of concrete structural representation of the present utility model.The motor tire replacer of present embodiment, shell 2 internal fixation one cycloidal-pin wheel retarder, the input end of cycloidal-pin wheel retarder and spanner 1 flexibly connect, and the mouth of cycloidal-pin wheel retarder is captiveed joint with sleeve 3.Sleeve 3 flexibly connects a quill 5, and quill 5 is outer a sleeve pipe 4 that is fixed together with shell 2, and there is a fixed arm 6 end of sleeve pipe.In order to adapt to the dismounting of different motor tires, be furnished with many covers and the suitable quill 5 of different nuts.The reduction ratio of above-mentioned cycloidal-pin wheel retarder is 17: 1.

During use, select suitable quill 5, fixed arm 6 is fixed between two bolts of tire according to the size of nut.Rotating spanner 1 subtracts device by cycloidal-pin wheel and drives quill 5 rotations, can dismantle nut easily.

Claims (4)

1. motor tire replacer, include spanner (1), shell (2) and sleeve (3), it is characterized in that: shell (2) internal fixation one cycloidal-pin wheel retarder, the input end of cycloidal-pin wheel retarder and spanner (1) flexibly connect, and the mouth of cycloidal-pin wheel retarder is captiveed joint with sleeve (3).

2. replacer according to claim 1 is characterized in that: sleeve (3) flexibly connects a quill (5), and quill (5) is outer a sleeve pipe (4) that is fixed together with shell (2), and there is a fixed arm (6) end of sleeve pipe.

3. replacer according to claim 1 and 2 is characterized in that: have many covers and the suitable quill (5) of different nuts.

4. replacer according to claim 1 and 2 is characterized in that: the reduction ratio of described cycloidal-pin wheel retarder is 17: 1.
