In the application, see figure (1,2,3,4,5,6,7,8,9,10) meet the emergency situation glancing impact in high vehicle speeds, right crus of diaphragm is when stepping on brake pedal, left foot also step on rapidly the pedal 51 of stopping, by main tie 52, main tie hook 53, conv 54, the pull bar hook 55 of stopping, again by the ground drive link 1 of stopping, stop reset of card key 11 in the frame 6 of the two side masters about pull bar 4 pull-ups simultaneously of stopping, the non-return card key 7 of leaving behind, meanwhile the fingertip 67 on the main tie hook 53 presses and conducting contact switch 68 in the conv 54, stator electromagnet 40 energisings produce magnetic field (Fig. 2-2,2-3), because this magnetic field S utmost point is extremely identical with the S of permanent-magnetic clamp 39, the two repels mutually, the permanent-magnetic clamp 39S utmost point and stator electromagnet 40 another utmost point N, polarity is opposite, the two attracts each other, under the effect of dual magnetic field force, permanent-magnetic clamp 39 is moved to the N utmost point by the S utmost point of stator electromagnet 40 rapidly, simultaneously, promote push rod 27, slide block 25 operations, and by slider arm 24, the push rod 23 the stopped frame 18 of stopping with promoting move downwards fast, the locality frame 18 of stopping is descending, the rubber in 19 the stopped piece 29 of stopping contact and produce friction rapidly with ground, this friction force is stopped with forcing and 19 is moved after quick along the oblique chute 31 of ground in the frame 18 of stopping, because the mutual action of non-return circlip groove 45 on non-return card key 7 and the slide block 25, slide block 25 is fixed and can't be retreated by non-return, the frame 18 of stopping can not move up with making, when after the oblique chute 31 in 19 edges is stopped on ground, moving, stop frame 18 with 19 the accumulative total of stopping highly constantly increase, stop 19 with rubber stop the piece 29 dead weight of vehicle pressure that bears also in continuous increase, under this inertia pressure, the rubber piece 29 of stopping has produced greatly friction force over the ground, and this resistance forces vehicle to be braked rapidly.Stop buffering, water conservancy diversion, the drainage of piece 91 of the point 88 of stopping, flame diversion trough 30, herringbone on the piece 29 because rubber is stopped, but make vehicle in the sand-gravel surface or all safety arrestments of quick and stable of rainwater road surface.

After car brakeing, the pedal 51 of stopping with unclamping, the contact switch 68 of stopping reset, disconnect stator electromagnet 40 power supplys, non-return card key 7 is pulled upwardly under reset tension spring 12 and power assistant spring 5 effects and breaks away from non-return circlip groove 45, two-way phase reversal switch 80 (see figure 7)s of motor 17 then reset on the opening automobile instrument carrier panel, connection motor 17 power supplys that reset, bevel gear 16 drives transmission bevel gear 44, screw rod 41 resets, screw rod cover 15, the thrust of utilizing screw rod 41 and screw rod cover 15 to produce is by slide block 25, slider arm 24, the push rod 23 of stopping, the ground frame 18 of stopping is pulled upwardly and resets, push rod 27 and push rod permanent-magnetic clamp 39 also reset simultaneously, reset of card key 11 snaps in the reset of card keyway 10 on the slide block 25, slide block 25 non-returns, and the anti-switch block 14 on the screw rod cover 15 presses front contact phase reversal switch 38 forward simultaneously, reset motor 17 power supplys by paraphase, contrarotation drives screw rod cover 15 by the screw rod 41 that resets and resets, and anti-simultaneously switch block 14 presses back contact phase reversal switch 37 backward, power cut-off, motor quits work.19 under retracing spring 85 effect, reset side by side stopping of said process.

Figure (2-4,2-5) utilizes energy stroage spring 46 to substitute push rod electromagnet 9, and its working process is identical with the push rod electromagnet.

When vehicle is met ice and snow road, stir the two-way phase reversal switch 77 on the instrument carrier panel, connect motor 63 (see figure 4)s in the conv 54, drive screw rod 61 and promote tooth bar push rod 62 contact switch 65 operations backward, push away on the tooth bar push rod 62 and refer to that 60 promote to pull out circle 59, pull out finger 70 by circle 69 drives of pulling out on the fork 58, make cylinder lever connecting rod ring 71 enter ice and stop in the hook groove of pull bar hook 74 by the stop hook groove 73 of pull bar hook 55 of ground, at this moment whole device is converted to by the ground system of stopping ices the system of stopping, when emergency brake of vehicle, the pedal 51 of stopping with depressing rapidly, main tie 52 is by conv 54 make contact switches 68, and by the ice pull bar hook 74 of stopping, ice the drive link 3 of stopping, ice pull bar 2 pull-ups of stopping and ice the card key of part of stopping, (its process with the part of stopping identical), ice tooth 34 of stopping, 35,36 at the ice frame 32 ice kiss the earth rapidly of stopping under 33 the drive of stopping, and at dead weight of vehicle, under the effect of inertia and oblique chute 31 (see figure 10)s, insert the ice face rapidly and produce resistance, force the quick non-skid braking of vehicle.When ice stops 33 when using on than the thin ice face, the flat tooth 36 of stopping helps to protect the road surface.

Embodiment 2:

Referring to Figure 11, (stop use part with embodiment 1) using ice in a flash, open the two-way phase reversal switch 108 on the instrument carrier panel, connect motor 103 power supplys, bevel gear 102 drives screw rod 95 by transmission bevel gear 94, by negative thread 107 in the screw rod slide block 98 screw rod slide block 98 is moved to front contact switch 96 along screw rod 95, and drive the tooth slide block 97 of stopping by chute 99 and move downwards along the teeth groove 105 of stopping, when the tooth 104 of stopping, 106 move out when stopping teeth groove 105, screw rod slide block 98 presses front contact switch 96 and cuts off motor 103 power supplys, the screw rod slide block 98 and the tooth slide block 97 of stopping are out of service, and ice is stopped and entered mode of operation (its using method is with embodiment 1).When not icing in a flash, oppositely open the two-way phase reversal switch 108 on the instrument carrier panel, motor 103, screw rod 95 reversings, screw rod slide block 98 contact switch 100 operations backward drive the upwards operation of tooth slide block 97 of stopping by chute 99, when the tooth 104,106 of stopping is return when stopping teeth groove 105, screw rod slide block 98 presses back contact switch 100, cuts off motor 103 power supplys, and screw rod 95 stops operating, the tooth slide block 97 of stopping resets and stops, ground stop 19 recover again the function of stopping.
