Below in conjunction with embodiment the utility model is further described, following each embodiment only is used to illustrate the technical solution of the utility model, but to not restriction of utility model.
Embodiment one
Shown in Fig. 1 to 2, emergency braking stop assisting device of automobile of the present utility model comprises: by the flexible arm seat 11 of master that is connected on the crossbeam, be hinged in the main telescopic boom 12 on the main flexible arm seat 11, be connected in helping that helping of main telescopic boom 12 ends stop that friction plate 13 forms and stop carriage component, by the flexible arm seat 21 of pair that is connected on the crossbeam, be hinged in the secondary telescopic boom 22 on the secondary flexible arm seat 21, being connected in secondary telescopic boom 22 terminal Lift Parts 23 forms control and helps and stop planker lifting assembly set, by the gas tank 31 that is installed on the vehicle frame, be communicated with gas tank and master, the tracheae 32 of secondary telescopic boom compression air cavity, the electromagnetic valve 33a of control gaseous break-make, 33b, 33c, 33d, combine the pneumatic part of controlling, the three parts that this is basic, in addition, also additional have to be connected on the crossbeam to be connected with main telescopic boom help the correspondence position that stops this end of friction plate also to dispose set pin 4, be used for fixing to help and stop carriage component.Control in the three parts helps the Lift Part 23 that stops in the planker lifting assembly set then by constituting with crossbeam bonded assembly hinged seat 23a, swing component 23b, main telescopic boom moving part 23c, from Fig. 3 and Fig. 4 as can be known, help that to stop friction plate 13 be to be composited by the upper strata, also be provided with a plurality of double wedges on the hard friction plate a, this double wedge termination sees through soft friction plate 13b, is exposed to soft friction plate 13b surface.This type of is provided with the structure of exposing soft friction plate surface, be applicable to that cold district is freezing and have the snow-up road surface to use, the dentation piece that protrudes can increase the ground ability of grabbing, and for southern grade road surface, then with adopt double wedge and the soft friction lining outside face of rubber-like flat or do not protrude slightly recessed even structure and be advisable.
During use, stop lock-switch press electromagnetic valve 33a, 33b the energising, electromagnetic valve 33c, 33d open and oil circuit on closed electromagnetic valve.
Stop drawing on the lock-switch power supply all to cut off: 33a, 33b closed electromagnetic valve, electromagnetic valve is opened on 33c, 33d and the oil circuit.
Open electromagnetic valve 33a, 33b (closing the electromagnetic valve on 33c, 33d electromagnetic valve and the oil circuit simultaneously), make compressed gas enter secondary telescopic boom 22 by flexible pipe, make secondary telescopic boom 22 be reduced to the position, open check plate set pin 4 simultaneously, put down swing component 23b, enter main telescopic boom 12 by hose compression gas, make main telescopic boom 12 prolong, help and stop friction plate 13 rapid insertions below the automotive wheel, make automobile break away from ground.
Must pull on stopping lock-switch during driving, (electromagnetic valve also is housed on oil circuit to be opened simultaneously) opens electromagnetic valve 33c, 33d, and (closing valve electromagnetic valve 33a, 33b simultaneously), automobile enters reverse gear; Compressed gas enters main telescopic boom 12 by flexible pipe, makes main telescopic boom 12 and help to stop friction plate 13 and reset, and compressed gas enters secondary telescopic boom 22 through flexible pipe again, and swing component 23b is resetted, and set pin 4 is stretched out stop friction plate 13 location with helping.
As everyone knows, when automobile in case of emergency, emergency brake automobile is stopped at once or shorten impact square from, crux is wheel and ground-surface friction; This device can will have soft friction plate 13b compound the helping stopping of upper strata hard friction plate 13a and the lower floor friction plate 13 of a plurality of double wedges (exceeding about the about 1cm of soft check plate) in a short period of time by air pressure (or oil pressure), pressure by vehicle weight contacts check plate firmly with ground, thereby the impact square that has shortened automobile greatly from, reduced the incidence of accident, the suitable especially car that kills of this device is malfunctioning, the rainy day that the road is sliding, the urgent stop in ice and snow sky.
The operation of this device is very simple, when you meet with emergency situation, presses rapidly as long as will stop lock-switch; This device will be by air pressure (or oil pressure), and moment is opened the check plate set pin, puts down crane, check plate is entered below the automotive wheel, make automobile back wheel break away from the road surface, and check plate is parked on the road surface firmly, wards off and has exempted to take place with the excessive accident of being brought of impulsive force by pressure.
When newly setting out on a journey, as long as will stop to draw on the lock-switch, automobile proceeds to shelves, and this device is promptly regained stop board and main telescopic boom automatically, shrinks an arm and stretches out crane is packed up by paying again, and set pin is automatically with check plate lock jail.
The gas of gas tank also can be used to inflate to wheel in addition.
