Abstract

A 'carpet'-type vehicle emergency brake device comprises a carpet coiling shaft installed on a beam, wherein a 'carpet' which is like a rolling screen door and is in a shape like a Chinese character 'men' is installed on the carpet coiling shaft, the 'carpet' is made through injecting rubber and a wire mesh, the 'carpet' is coiled on the carpet coiling shaft through a coiling machine or is tiled on a road, the coiling machine is controlled by a coiling machine switch, and the coiling machine switch is installed on the more concealed place of a driving platform, the brake device can enable the'carpet' to be rapidly tiled on the road when the brakes fails and before the instant of car crash, enables rear wheels of the driving vehicle to enter the 'carpet', once the rear wheels enter the carpet, the vehicle instantly stops the forward moving, since the 'carpet' is suspended on the carpet coiling shaft of the beam, the contact area between the 'carpet' and the road is obviously increased,the friction between the 'carpet' and the road is also rapidly increased, the brake device can completely overcome the inertia of the vehicle and the friction force generated by front wheels which are still in driving, and the vehicle can instantly stop the forward moving, thereby effectively preventing tragedies caused by any brake failure.

Description

" carpet " formula emergency vehicle brake gear

Technical field

The utility model relates to a kind of " carpet " formula emergency vehicle brake gear.

Background technology

At present, known vehicle brake device all is to take the steel ring system of tire is moved, and this brake time has been grown, and braking effect will reduce, and in case of emergency, the tragedy that brake failure causes car crash takes place very easily.So far still there is not the disaster that actv. brake technology can stop brake failure to cause.Not having existing technology can reference

The utility model content

In order to solve the deficiency of existing brake technology, the utility model provides a kind of " carpet " formula emergency vehicle brake gear, comprise the volume blanket axle that is installed on the crossbeam, door font " carpet " as rolling screen door is housed on the volume blanket axle, (" carpet " is injection molded by rubber and wire net) " carpet " is wound on the blanket axle by rolling-up machine or exhibition is placed on the highway, rolling-up machine is by the control of rolling-up machine switch, and the rolling-up machine switch is installed in the more hidden place of operator platform.

The beneficial effects of the utility model are: in brake failure, be about to take place the moment of car crash, this brake gear can make " carpet " promptly to tile on the highway, allow travel in the trailing wheel of vehicle enter on " carpet ", in case trailing wheel enters carpet, vehicle will halt at once.Because " carpet " is to hang on the volume blanket axle of crossbeam, " carpet " significantly increases with the area of contact of highway, friction between " carpet " and the highway also strengthens rapidly, it can overcome the coherence of vehicle and the friction force that front-wheel is still produced fully in driving, so, vehicle can halt at once, thereby avoids any tragedy that causes because of brake failure effectively.

Below in conjunction with the embodiment of accompanying drawing, the utility model is further specified.

Description of drawings:

Fig. 2 is that " carpet " partly stretches view

Among Fig. 1: 1---" carpet ", 2---volume blanket axle, 3---crossbeam, 4---rolling-up machine, 5---the rolling-up machine switch, 6---operator platform

The specific embodiment

As shown in Figure 1, a kind of " carpet " formula emergency vehicle brake gear comprises " carpet " 1, volume blanket axle 2, crossbeam 3, rolling-up machine 4, rolling-up machine switch 5, operator platform 6.When vehicle needs emergency brake, press opening of rolling-up machine switch 5, " carpet " 1 is put on the highway with regard to exhibitions, in case trailing wheel reaches " carpet " 1, volume blanket axle 2 will be held " carpet " 1, stop the driving of trailing wheel to highway, emergency brake finishes, and retreats vehicle, trailing wheel leaves " carpet " 1, press the pass of rolling-up machine switch 5, " carpet " 1 will go by rollback, uses when treating that next time is emergent again.

Claims (1)

1. " carpet " formula emergency vehicle brake gear, it is characterized in that: volume blanket axle (2) is installed on crossbeam (3), both be fixed with and reeled on the volume blanket axle (2), can open up again on the carpet (1) put, the crossbeam (3) rolling-up machine (4) is installed, rolling-up machine (4) is by rolling-up machine switch (5) control that is installed on the operator platform (6).
