Description

The device of quick change of wheels

Technical field

The present invention relates to a kind of car wheel and change instrument, particularly a kind of device of quick change of wheels.

Background technology

Car is in long use, and owing to wear on tyres and unexpected reason, tyre explosion or tire pressure lose to the greatest extent, need in time to change fast spare tyre, using existing driver's tool all is the single nut operation of turn, not only time-consuming, efficient is low, and is difficult to realize diagonal angle nut predetermincd tension unanimity.

Summary of the invention

The device that the purpose of this invention is to provide a kind of quick change of wheels uses the device change of wheels of this quick change of wheels, saves time, high efficiency, is convenient to realize diagonal angle nut predetermincd tension unanimity, improves the fatigue life of bolt and the reliability that wheel is installed.

The present invention is the sleeve that has magnetic by two, transmission system and folding afterburning handle are formed, transmission system is by input shaft, driving gear, driven shaft, driven gear, gear ring, support, knob, end cap and nylon sleeve are formed, support is set in the knob with nylon sleeve, gear ring is to be bolted to the knob outer rim, end cap is located at the knob front portion, transmission system is coated between knob and the end cap, driving gear is sheathed to be fixed on the input shaft, input shaft is set in the support with nylon sleeve, driven gear is sheathed to be fixed on the driven shaft, two driven shaft symmetries are positioned at the both sides of input shaft, two driven shafts are set in the support with nylon sleeve, two driven gears of driving gear and both sides are meshing with each other, and two driven gears and gear ring are meshing with each other; Two sleeves are positioned at the end cap outside, and two sleeves are set in the outer end of two driven shafts respectively, and two handles of folding afterburning handle relatively rotate 180 ° and are set on the rear end that input shaft exposes.

Working process of the present invention and principle are as follows:

1, unloading process: two jacket casings are located on two nuts at wheel diagonal angle, the rotation direction both hands of pressing nut rotate folding afterburning handle, input shaft drives the driving gear rotation, driving gear drives the driven gear rotation, driven shaft drive sleeve turns to nut is only unscrewed, pull down folding afterburning handle, rotation direction turning knob by contrary nut, knob drives gear ring and rotates, gear ring drives the driven gear twirl to screwing off nut, repeat aforementioned work the diagonal angle nut of remainder is screwed off, finish removing vehicle tyres work;

2, installation process: two nuts are put in the sleeve, allow nut aim at two bolts at wheel diagonal angle respectively, rotation direction turning knob by contrary nut, knob drives gear ring and rotates, gear ring drives the driven gear twirl, driven shaft drives sleeve and rotates, sleeve turn nut ends to changeing motionless knob, load onto folding afterburning handle, the rotation direction both hands of pressing nut rotate folding afterburning handle, and input shaft drives the driving gear rotation, driving gear drives the driven gear rotation, driven shaft drives sleeve and turns to and nut is screwed end, and repeats aforementioned work the diagonal angle nut of remainder is screwed, and finishes wheel-mounted work.

The invention has the beneficial effects as follows: save time, high efficiency, be convenient to realize diagonal angle nut predetermincd tension unanimity, improve the fatigue life of bolt and the reliability that wheel is installed.
