Abstract
Provided is an anti-slipping extensible safety wheel of electric vehicle and capable of being used on wet and slippery roads in rainy and snowy days. Left and right fixed frames on a wheel axle of rears wheels of the electric vehicle are fixed on two sides of the rears wheels of the electric vehicle through the axle and nuts, and guide rail grooves and positioning bolts are arranged on the left and right fixed frames. When left and right connecting rods respectively penetrate into the left and right guide rail grooves, left and right positioning bolts are tightened after anti-slipping positioning holes in left and right connecting rods are aligned to the left and right positioning bolts, left and right anti-slipping safety wheels are installed on the wheel axle of the left and right connecting rods, left and right anti-slipping safety wheel fixing nuts are tightened, and anti-slipping positioning holes and retraction positioning holes are formed in the left and right connecting rods.
Description
Affiliated technical field
The utility model relates to a kind of battery-driven car anti-skid safety wheel apparatus, especially can retractable safety the battery-driven car anti-skid safety wheel of wheel.
Background technology
At present, known battery-driven car structure is made up of preposition steering wheel and rearmounted drive wheel.In the time that sleet sky road is wet and slippery, cause battery-driven car to overturn because breakking away, cause difficulty to normal driving.
Summary of the invention
Can not be anti-skidding in order to overcome existing battery-driven car, in the time that sleet sky road is wet and slippery, cause battery-driven car to overturn because breakking away, cause difficult deficiency to normal driving, the utility model provides a kind of battery-driven car anti-skidding retractable safety wheel, the anti-skidding retractable safety wheel of this battery-driven car can not only make battery-driven car normal driving at ordinary times, and can be anti-skidding in the time that sleet sky road is wet and slippery easily, prevents the overturning of battery-driven car because breakking away and causing.
Technical scheme
The utility model solves the technical scheme that its technical matters adopts: on the wheel shaft of rear wheels of electric vehicle, and a left side, right fixed mount, is fixed on rear wheels of electric vehicle both sides, a left side by wheel shaft and nut, on right fixed mount, be provided with guide-track groove and dowel bolt, by a left side, right pipe link penetrates respectively a left side, right guide-track groove, works as a left side, anti-skidding knock hole on right pipe link is with left, after right dowel bolt aligns, screwed in place bolt, a left side, right anti-skid safety wheel is arranged on a left side, on the wheel shaft of right pipe link, tighten a left side, right captive nut, at this moment, a left side, right anti-skid safety wheel just can provide a strong point, due to each in rear wheels of electric vehicle both sides, an anti-skid safety wheel is installed, no matter battery-driven car is turned left or right side is sliding, can not make battery-driven car overturning, not needing at ordinary times when anti-skidding, to unclamp a left side, right dowel bolt, by a left side, on right pipe link, be pushed into and shrink knock hole with left, right dowel bolt, to timing, is tightened a left side, right dowel bolt, just can normal driving, reaches battery-driven car normal driving at ordinary times, need can be anti-skidding when anti-skidding object.
Beneficial effect
The beneficial effects of the utility model are, can be in battery-driven car normal driving, prevent that easily battery-driven car is in the time that sleet sky road is wet and slippery, cause battery-driven car to overturn because breakking away, left and right anti-skid safety wheel only adopts left and right pipe link, left and right fixed is connected with rear wheels of electric vehicle wheel shaft, simple in structure.
