Abstract

The emergency system comprises brake control rod connected with brake by means of connection system. The brake is equipped with size-correspondent friction disks which are respectively positioned in front of wheel and in back of one, and connected into one body by means of fixing frame. The front friction disk is connected with rear friction disk by means of tension wire through restoring spring and tension wire hole on the forced frame, and can be directly frictionized with ground instead of wheel between wheel and ground when the brake is applied. The tension wire can apply the friction resultant produced when the brake is applied to the forced frame, and the restoring spring can make the friction disk be in contact state with ground before restoration, and after restoration it can make them be in non-contact state. Said system is simple and reliable in structure, and can effectively apply emergency brake.

Description

Emergency system for brake failure of vehicle

The present invention relates to a kind of emergency system for brake failure of vehicle, be used for the invalid effect of control brake.

Automobile and other vehicle are the transport facilitys of using always, and braking is its indispensable system.The brake system of widespread usage is made up of air compressor, compressed air brake cylinder, brake activation valve, air pressure adjusting valve, pipeline etc. at present, but, its calibration package for want of, if occur wherein any one link malfunctioning suddenly or because of odjective cause as snowfield, the ice face, muddy and ruthed lane or when making the invalid extraordinary circumstances that maybe can not be effective of braking because of friction is little, and feel simply helpless, its consequence is hardly imaginable.In addition, when automobile is parked on the sloping road, because the cause specific automobile is from line slip, its consequence is hardly imaginable equally.

The objective of the invention is to remedy the extraordinary circumstances of above-mentioned prior art and a kind of emergency system for brake failure of vehicle is provided, this emergency system for brake failure of vehicle can not only effectively emergency brake invalid condition, and other function arranged, promptly can be used as vehicle limited slip and prop up thing, as, when automobile was parked in sloping road, for avoiding automobile from line slip, a thing commonly used was anti-skidding.And get in touch because of it establishes one's own system not have with former brake system, be not subjected to the influence of original system, thus emergent reliable, and can doublely do a page son and pull.

In order to achieve the above object, the present invention adopts a kind of emergency system for brake failure of vehicle, thereby it is by operating control with can directly act on ground-surface drg and forms with the contact surface increasing coefficient of friction that replaces malfunctioning brake system or increase braking to reach corresponding purpose.Described operating control has the function of control brake device, described drg has and directly acts on ground-surface Friction disk and fixed mount thereof and be connected with operating control by being in transmission connection, keep its relevant position by returning device, described returning device has that Friction disk and ground directly rub before return, and Friction disk and ground are contactless state behind return, make a concerted effort because of the friction that is loaded on this through line of pull that friction produces by stressed carrying, by the pinch roller stationary rack with slip-off preventing.

As a kind of improvement of the present invention, brake plate and wheel respective face are grooved, grooved can prevent that brake plate is to other direction skew, sheave shaft is housed to reduce the friction of tire and brake plate in groove, glancing impact is depending on wheel and ground directly rubs, and the another side of brake plate is provided with anti-skidding thorn, as, triangular prism, cone etc. are to increase coefficient of friction.

In the present invention, convenient for Friction disk is changed, and line of pull, backguy and pull back spring structure are convenient, Friction disk and fixed mount dongle configuration, and fixed mount is a c type slot, Friction disk is corresponding plug-in unit.

Emergency system for brake failure of vehicle of the present invention is simple in structure, and cost is low, because of its operating control control brake device directly acts on ground, can increase coefficient of friction, and relatively independent because of its system again, failure factor is few, and emergency brake is reliable for effect.Simultaneously, also can be used as automobile skidproof thing when the parking of sloping road.

Below in conjunction with accompanying drawing emergency system for brake failure of vehicle of the present invention is described in further detail.

Fig. 1 is the scheme drawing of emergency system for brake failure of vehicle of the present invention.

Fig. 2 is the sagittal section-drawing of emergency system for brake failure of vehicle shown in Figure 1.

Fig. 3 is the running condition figure of emergency system for brake failure of vehicle shown in Figure 1.

Fig. 4 is the birds-eye view of emergency system for brake failure of vehicle shown in Figure 1.

Fig. 5 is the Friction disk diagrammatic sketch.

From Fig. 1 scheme drawing of the present invention shown in Figure 2, Fig. 3 embodiment figure as can be seen, operating control is that an end is that the handle other end is and connecting rod bonded assembly joystick 20, its end connects tooth bar connecting rod 12, and the pulley 10 of drive transmission backguy 9 on stressed 6 is connected with the Friction disk 1 of drg to drive corresponding driving wheel 17, the tooth bar connecting rod is fixing in case the engagement disengaging by pinch roller 8, before and after Friction disk 1 by front and back arm 14 at an angle and be the fixed mount that vertical fixing links with minor axis 2 and fix, this fixed mount is fixed point with the relevant position of vehicle frame and rotarys connection with the wheel direction, front and back arm 14 is elastic telescopic, before and after Friction disk 1 be connected by the line of pull hole 11 of line of pull 3 by pull back spring 4 and stressed 6, Friction disk 1 is grooved and wheel is corresponding, and stressed 6 for being made up of the post steel body in pulley 10 and line of pull hole 11 and its reinforced rib 5 and being fixed on the relevant position.

Calibration package of the present invention carries out work by following mode: Fig. 1 is in off working state, when enabling, make drive wheel 17 drive transmission backguy 9 motions and pulling back Friction disk 1 to stressed 6 by joystick 20 pulling tooth bar connecting rods 12,1 of friction places between ground and the wheel before making, elastic telescopic makes it to depend on wheel and ground directly rubs because fixed mount front and back arm 14 is, the friction of Chan Shenging is loaded into stressed 6 by the line of pull 3 of 1 of front and back Friction disk therefrom, Friction disk 1 is that grooved is corresponding with wheel to make it not can be because of skew ineffective and damage fixed mount, dress sheave shaft a is to reduce the friction between wheel and the Friction disk 1, as Fig. 2 in Friction disk 1 groove.When removing emergency rating, wheel moves to when suitable backward, by pull back spring 4 it is retracted original state by joystick 20.When then making another backguy 21 Friction disk 1 before reversing sense motion and pulling by joystick 20, glancing impact backward makes afterwards to stressed 6 that Friction disk 1 places between ground and the wheel, to realize its effect.When removing emergency rating, wheel moves forward to when suitable, by joystick 20, by pull back spring 4 it is retracted the hope shape.

Aspect material, line of pull 3 and backguy 9,21 select steel rope to be advisable, arm 14 is that the thickness pipe is nested before and after the fixed mount, built-in spring can be changed corresponding Friction disk 1 according to the needs of road surface or other situation, presses dress mudwing 15 between the front and back Friction disk 1 in order to avoid muddy water influences equipment.

Except structure shown in above-mentioned, system of the present invention can also have other structural distortion, and does not depart from the scope of the present invention.
