About embodiment:
Refer to Fig. 2 and Fig. 3, the anti-turning-up devices of vehicle of the present embodiment, comprise first to fourth guard sheaver 21, the rotating front axle two ends being installed on described vehicle of first and second guard sheaver 21 lay respectively at the inner side of two front vehicle wheels, the 3rd and the 4th guard sheaver 21 is rotating to be installed on the rear axle two ends of described vehicle and to lay respectively at the inner side of two rear wheels; The external diameter of described first to fourth guard sheaver 21 is all less than the external diameter of described wheel.Wherein:
In order to protect conformability and the stability of this anti-turning-up devices, make the external diameter of first to fourth guard sheaver 21 identical, and the difference of the external diameter of this first to fourth guard sheaver 21 external diameter and wheel is in the scope of 5 ~ 100mm.In this example, the difference of the external diameter of this first to fourth guard sheaver 21 and the external diameter of described wheel is at 70mm.Understandable, in other examples, between the wheel that each guard sheaver 21 is adjacent, the difference of their external diameter can not be identical, the external diameter difference 5mm of the wheel that the such as external diameter of the first guard sheaver 21 is adjacent, the external diameter difference 20mm of the wheel that the external diameter of the second guard sheaver 21 is adjacent, the external diameter difference 40mm of the wheel that the external diameter of the 3rd guard sheaver 21 is adjacent, external diameter difference 70mm of the wheel that the external diameter of the 4th guard sheaver 21 is adjacent etc., in this approach, same first to fourth guard sheaver 21 that can enable is taken as spare tyre use when blowing out.Above-mentioned external diameter difference determines wheel when blowing out, the crooked degree of vehicle.The external diameter difference of the wheel that such as the first guard sheaver 21 is adjacent is at 5mm, and so when this wheel is blown out, the vehicle tilt that this vehicle is blown out to this is less.The external diameter difference be such as adjacent when the 4th guard sheaver 21 is again at 70mm, and so when blowing out when this wheel, this vehicle is comparatively large to this vehicle tilt of blowing out, but above-mentioned degree of dip is all in controlled range.
In order to save raw MAT'L, the axial width of first to fourth guard sheaver 21 is approximately 1/2 of common wheel, as long as the wheel that this guard sheaver 21 can replace this to blow out after common wheel is blown out temporarily.
Independently travelling to leave four wheels alone, making first to fourth guard sheaver 21 respectively near the wheel that is adjacent, but guard sheaver 21 does not contact with wheel adjacent to the one side of wheel.Particularly: one the 4th preset distance of being separated by between the rear wheel that be separated by between the rear wheel that one second preset distance of being separated by between the front vehicle wheel that one first preset distance of being separated by between the front vehicle wheel that described first guard sheaver 21 is adjacent, the second guard sheaver 21 are adjacent, the 3rd guard sheaver 21 are adjacent one the 3rd preset distance and/or the 4th guard sheaver 21 are adjacent.
Above-mentioned first preset distance, the second preset distance, the 3rd preset distance and the 4th preset distance get value range 5 ~ 50mm.In order to ensure the conformability of anti-turning-up devices, make the first preset distance, the second preset distance, the 3rd preset distance and the 4th preset distance equal.In this example, first to fourth preset distance all gets 30mm.Certainly, in other examples, first to fourth preset distance can be unequal, and such as the first preset distance gets 5mm, and the second preset distance gets 15mm, and the 3rd preset distance gets 30mm, and the 4th preset distance gets 40mm.Same, each guard sheaver 21 also determines the angle of vehicle flat tire rear-inclined with the spacing between corresponding wheel, and under same external diameter difference, the angle of spacing inclination of vehicle far away is larger, and the angle of the nearlyer inclination of vehicle of spacing is less.
Anti-turning-up devices of the present invention, when mounted can be identical with the mounting means of wheel, makes each guard sheaver 21 be installed on the inner side of corresponding wheel.In normal vehicle operation process, what this guard sheaver 21 cut little ice is positioned in forward and backward vehicle bridge, when one of them wheel is blown out, the wheel that guard sheaver 21 replacements corresponding are with it blown out, this guard sheaver 21 rotates as common wheel, to prevent after vehicle flat tire because the difference of height of left wheel rear right wheel is too large, after beating bearing circle, easily cause the problem of vehicle rollover.If the unexpected lack of equilibrium of vehicle body, chaufeur is flurried, nervous misoperation, adds that vehicle two-wheeled and ground difference of height are too large, easily causes vehicle rollover.This anti-turning-up devices only needs employing four guard sheaver 21 tires can realize the safety precaution of vehicle, its cost is lower, substantially increase life safely, decrease the generation of traffic accident.
The invention also discloses a kind of four-wheeled vehicle, it comprises above-mentioned anti-turning-up devices.This four-wheeled vehicle have employed above-mentioned anti-turning-up devices, can increase the safety performance of this self-propelled vehicle, and safety performance is purchase the factor that car people values most always, to a certain extent, too increases the sales volume of this self-propelled vehicle, promotes the satisfaction of user.
