The position of melon formula

braking earth anchor

22,24,25 and pole type brake earth anchor 15 is for inserting road surface inside brake state among Fig. 1-3.Non-glancing impact can rise parallel with girder, by 13 and 18 lockings of control pin.

Whole principle of work is such:

Work as high vehicle speeds, in extraordinary circumstances, utilize friction braking system not brake immediately, when avoiding major traffic accidents, spur control pull rod 29 and 32 by driver operation,

control pin

18 and 13 is pulled out in control angular pole 31 and 33 actions, the melon formula braking earth anchor 22 of two girders, 24,25 and pole type brake earth anchor 15 be subjected to gravity and spring 9 and 28 effects that it is fallen to touch the road surface, be subjected in vehicle gravity and the force of inertia effect pole type brake earth anchor 15 oblique cutting approach bodies after touching the road surface, toggle 14 is held rod-type earth anchor 15, make it keep oblique cutting state (see figure 1), be subjected to the melon anchor palm 27 at melon anchor 25 back sides of vehicle gravity and force of inertia effect melon formula braking earth anchor to touch road surface posterior approach face after touching the road surface, move up into melon anchor cover cylinder 22 certain-lengths on melon anchor 25 and melon anchor pole 24 pressurizeds, vehicle moves ahead, melon anchor 25 turns over certain angle makes its tip touch the road surface, hind axle thick stick 23 is depressed into melon anchor cover cylinder 22 and makes in the melon anchor 25 oblique cutting approach bodies, along with the vehicle melon anchor pole 24 that moves ahead is pulled out, make in melon anchor 25 whole oblique cutting road surfaces.

Insert the anchor 15 of the rod-type in the road surface and melon formula earth anchor 25 and be subjected to road body structure drag effect and consume the machine mechanical energy that vehicle gravity and force of inertia produce, the shortest time apart from interior emergency braking.

During brake off, vehicle falls back and transfers to pole type brake earth anchor and melon formula braking earth anchor, it is propped up in the control anchor again and sits in 11 and 8, by 13 and 18 lockings of control pin.

The present invention compared with prior art utilizes motor vehicles gravity and inertia force that braking earth anchor anchor head 25 and 15 is inserted in the road surface, and the mechanical energy by road body structure resistance consumption vehicle inertia power and power produce realizes the shortest time distance inside brake. Avoid the common major traffic accidents that take place at braking procedure, open up the new way of braking under the motor vehicles deadly condition.

Advantage of the present invention is:

1. earth anchor inserts in the road surface, and the braking time distance is the shortest under the deadly condition.

2. simple in structure, behaviour's body is convenient, and braking is reliable.

3. open up the new way of braking under the power actuated vehicle deadly condition.
