Less than two kinds, annual compound growth rate about 14.8%.Develop at this rate, it is contemplated that the year two thousand twenty China's automobile guarantee-quantity will break through 200,000,000
.Increasing with car ownership, the workload of car repair shop service worker is continued to increase.By actual servicing operations
Estimation, the general small maintenance of car was maintained in a hour between two hours greatly at 30-40 minutes.With the increasing of automobile quantity
Many, car owner etc. lengthens the time to be repaired, service worker's burden.
Maintenance vehicle increases, for 4S shops, increases traffic pressure, the local pressure of parking；For car owner, etc.
Time to be repaired lengthens, and wastes the quality time of itself；For maintenance mans, operating pressure increase, easily tired, shadow
Work quality and efficiency are rung.Auto repair maintenance purpose is to ensure that the safe driving of car owner, is ensureing the same of work quality
When also to stress the operating efficiency of itself.To solve the above problems, it is necessary to be equipped with more efficient instrument auxiliary for service worker
Maintenance.
Utility model content
For the shortcoming for overcoming prior art to refer to, the utility model provides a kind of Combined automobile tyre dismantling device, can
To effectively improve the work quality and efficiency of vehicle maintenance maintenance.
The utility model solve its technical problem use technical scheme for：A kind of Combined automobile tyre dismantling device, bag
Include and at least one screw tightness mechanism be installed on substrate and driving gear, the substrate, the screw tightness mechanism include from
Moving gear, connecting shaft and box spanner, the connecting shaft are pivotally mounted on the substrate, and one end of the connecting shaft is stretched out
The side of the substrate simultaneously connects the driven gear, and the driven gear is connected by meshing transmission with the driving gear, described
The other end of connecting shaft stretches out the opposite side of the substrate and connects the box spanner there is provided torque output；The connecting shaft
On jaw clutch is installed in the opposite side of the substrate.
The screw tightness mechanism also includes compression spring, and the two ends of the compression spring contradict the connection base respectively
Plate and the jaw clutch, aid in the installation positioning of the connecting shaft on the substrate, the compression spring is according to vapour
Car lug nut screwing force is 120Nm regulation, selects the holddown spring of appropriate coefficient of elasticity.
The quantity of the screw tightness mechanism be 4 or 5, all screw tightness mechanisms using the driving gear as
Center circumferential is uniformly installed on the substrate, and each screw tightness mechanism coordinates according to the actual rim nut relative position of automobile
Size, the relative installation of fixed driven gear.
The tooth form of the jaw clutch is right-angled trapezium shape, it is therefore an objective to prevents lug nut tension and sets skidding to imitate
Really, its hypotenuse angle is determined by lug nut specified torque through force analysis, and general to use 45 ° -60 °, another right-angle side is wheel
Tire nut is unscrewed and designed, convenient disposable dismounting.
The driving gear and the driven gear use straight spur gear.
Being provided with the axis of the driving gear is used to connect impact gun or the four square holes seat of other drive devices.
The beneficial effects of the utility model are：The design is simple in construction, and people can be by hand after being installed on electrical equipment
Break the light angle from main regulation background light.
