The specific embodiment
Below in conjunction with accompanying drawing, a kind of preferred implementation of the present invention is described in detail.
As shown in Fig. 2,3 and 4, three axle passenger vehicles comprise that propons 9, back axle 10 and follow-up bridge 11, three bridges all carry out air feed by air bag, and the pressurized air in air bag is to distribute through combiner valve 8 or triple valve 7 by the source of the gas in air bag air receiver 6.Wherein the air bag air feed of follow-up bridge 11 can also be controlled by reverse gear switch 12, the signal output part of reverse gear switch 12 connects input circuit one end of air bag relay 13, the other end ground connection of this input circuit, output loop one end of air bag relay 13 connects power supply, the other end connects respectively the signal input part of the air bag electromagnetic valve 14 at follow-up bridge two ends, the exhausr port of air bag electromagnetic valve is communicated with follow-up bridge air bag by by pass valve 15, wherein 15 pairs of air bag air pressure of by pass valve limit, and in the present embodiment, setting value is 150KPa.When car load advances, reverse gear switch 12 conductings, make 13 conductings of air bag relay, air bag Control air bag electromagnetic valve a, the conducting of b mouth, and the pressurized air in air bag air receiver 6 carries out normal air feed to follow-up bridge air bag through air bag electromagnetic valve 14 and by pass valve 15; When car load is when moveing backward state, reverse gear switch 12 disconnects, and then 13 disconnections of air bag relay, air bag Control electromagnetic valve b, the conducting of c mouth, follow-up bridge air bag internal gas pressure exhausr port from air bag electromagnetic valve 14 under the restriction of by pass valve 15 is discharged, and is down to setting value.Follow-up bridge air bag air pressure reduces, to reduce loading of tire, thus the wearing and tearing on tire and ground when reducing reversing and turning to.
The invention provides a kind of control method of three axle passenger vehicle follow-up bridge abrasionproof tires, the control setup of realizing this control method comprises car load instrument 1, follow-up bridge controller 2, follow-up bridge relay 3, follow-up bridge electromagnetic valve 4 and follow-up bridge cylinder 5, wherein the signal output part of car load instrument 1 connects the signal input part of follow-up bridge controller 2, follow-up bridge controller 2 signal output parts connect input circuit one end of follow-up bridge relay 3, the other end ground connection of this input circuit, output loop one end of follow-up bridge relay 3 connects power supply, and the other end connects the input end of follow-up bridge electromagnetic valve 4; Described follow-up bridge electromagnetic valve 4 has a, b, tri-gas ports of c, and wherein a gas port is communicated with supply air line, and b gas port is communicated with the gas port of follow-up bridge cylinder, and c gas port is directly communicated with atmosphere; Follow-up bridge cylinder 5 is connected on the brake equipment of follow-up bridge, can lock follow-up bridge 11.Car load instrument 1 is for gathering the actual vehicle speed of car load driving, and actual vehicle speed signal can be sent in follow-up bridge controller 2, follow-up bridge controller pre-sets the banning of turning movement speed of a motor vehicle, conventionally under this speed of a motor vehicle, vehicle can not turn to, the banning of turning movement speed of a motor vehicle is according to the different difference that exist of each vehicle, the three axle passenger vehicles of take in the present embodiment are example, the banning of turning movement speed of a motor vehicle can be preferably 35 kilometers/per hour.Follow-up bridge controller 2 is after receiving the actual vehicle speed signal of car load instrument 1 transmission, the banning of turning movement speed of a motor vehicle of this actual vehicle speed and setting is compared, then the break-make of follow-up bridge relay 3 is controlled in judgement, and by follow-up bridge electromagnetic valve 4, control 5 pairs of follow-up bridges of follow-up bridge cylinders 11 and carry out lockedly, prevent that follow-up bridge generation relative sliding from causing follow-up bridge wear on tyres.
In order to reduce the wearing and tearing of three axle passenger vehicle follow-up bridge tires, the present invention according to car load advance, advancing turns to and the three kinds of operating modes of moveing backward are carried out respectively the control of abrasionproof tire.For convenience, 35 kilometers of banning of turning movement speed selections/per hour, concrete is described below:
As shown in Figure 2, the actual vehicle speed gathering when car load instrument 1 be more than or equal to 35 kilometers/per hour, follow-up bridge controller 2 sends a voltage signal by 3 conductings of follow-up bridge relay, the a of follow-up bridge Control follow-up bridge electromagnetic valve 4, the conducting of b mouth, now from the pressurized air in air bag air receiver 6, through follow-up bridge electromagnetic valve 4, give follow-up bridge cylinder 5 air feed, follow-up bridge cylinder moves, follow-up bridge 11 is locked, follow-up bridge can not turn to, while guaranteeing that vehicle advances under being more than or equal to the 35 kilometers/speed of a motor vehicle hourly, can there is not relative sliding in follow-up bridge tire, reduce the wearing and tearing of tire.
As shown in Figure 3, the actual vehicle speed gathering when car load instrument 1 be less than 35 kilometers/per hour, follow-up bridge controller 2 does not send voltage signal, follow-up bridge relay 3 disconnects, the b of follow-up bridge electromagnetic valve 4, the conducting of c mouth, and follow-up bridge cylinder 5 internal gas pressures are discharged in atmosphere by the c gas port of follow-up bridge electromagnetic valve, follow-up bridge 11 is not locked, guarantee that vehicle advances while turning under being less than the 35 kilometers/speed of a motor vehicle hourly, the not locked energy of follow-up bridge follow-up steering, reduces the wearing and tearing of tire.
Above-mentioned two situations automobile is in forward travel state, reverse gear switch 12 conductings, and follow-up bridge air bag carries out normal air feed.
As shown in Figure 4, when the actual vehicle speed of car load instrument 1 collection is negative value, represent that vehicle is in reverse travel state, now follow-up bridge controller 2 sends voltage signal, make 3 conductings of follow-up bridge relay, follow-up bridge Control follow-up bridge electromagnetic valve a, the conducting of b mouth, from the pressurized air in air bag air receiver 6, through follow-up bridge electromagnetic valve 4, give follow-up bridge cylinder 5 air feed, the action of follow-up bridge cylinder, follow-up bridge 11 is locked, follow-up bridge can not turn to, and guarantees that vehicle follow-up bridge tire when reversing relative sliding can not occur, and reduces the wearing and tearing of tire.
Follow-up bridge now, in locking state, if need to turn in reversing process, will certainly cause follow-up bridge tire and ground to rub, and causes follow-up bridge tire life to reduce.With reference to Fig. 4, can reduce the air pressure in follow-up bridge air bag by reverse gear switch 12, thereby reduce the friction with ground, be specially: when car load is when moveing backward state, reverse gear switch 12 disconnects, and then 13 disconnections of air bag relay, air bag Control electromagnetic valve b, the conducting of c mouth, follow-up bridge air bag internal gas pressure exhausr port from air bag electromagnetic valve 14 under the restriction of by pass valve 15 is discharged, and is down to setting value.
