Fig. 2 is the structural representation of the oil passage control valve among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.
Referring to Fig. 1; In the present embodiment, oil passage control valve 1 is installed on the car body with oil passage control valve 2, and is visible from figure; Oil passage control valve 1 is installed between pedal of clutch 3 and the power-transfer clutch working barrel 4, and oil passage control valve 2 is installed between brake pedal 5 and the total working barrel 6 of brake.The pressure oil of fuel tank 7 is got into from the left oil inleting port 101 of oil passage control valve 1 and the left oil inleting port 201 of oil passage control valve 2 by 5 controls of pedal of clutch 3, brake pedal respectively, after total oil outlet 206 of total oil outlet 106 of oil passage control valve 1 and oil passage control valve 2 comes out, enters into power-transfer clutch working barrel 4, the total working barrel 6 of brake again.Lead limit switch 8 is installed under the Das Gaspedal 9, and electronics oil pump 10 is parallel on the lead limit switch 8 with electronics oil pump 11.The oil inlet of electronics oil pump 10 and electronics oil pump 11 is connected with fuel tank 7; Its two oil outlets are connected with the right oil inlet 102 of oil passage control valve 1 and the right oil inlet 202 of oil passage control valve 2 respectively, through right oil inlet pressure oil are introduced respectively behind two oil passage control valves from total oil outlet 106 and 206 of two oil passage control valves again and are come out to enter into respectively power-transfer clutch working barrel 4, the total working barrel 6 of brake.Also visible from figure, between the oil outlet of electronics oil pump 10 and electronics oil pump 11 and fuel tank 7, also be connected with by pass valve 12 and by pass valve 13 respectively, be used for the oily flow of control oil channel, the oil of by pass valve is back in the fuel tank.In the present embodiment, the electronics oil pump adopts 12V electronics oil pump, and model is DP35, and specification is 3802; Said lead limit switch model is DEL1 * 1, and specification is LXJM1-9101; The model of said by pass valve is PB25B.
Referring to Fig. 2, be the structural representation of the oil passage control valve 1 of present embodiment.Visible from figure; Left oil inleting port 101 and right oil inlet 102 be located at respectively oil passage control valve 1 valve body the right and left above; The position of left, center, right is respectively equipped with left oil outlet 103, middle oil outlet 104, right oil outlet 105 below the valve body, and these three oil outlets all are connected on total oil outlet 106; The valve body two ends are equipped with end cap 109.Be provided with spool 110 in the body cavity, spool 110 is divided into left chamber 111 and right chamber 112 with body cavity, left oil inleting port 101 and left chamber 111 UNICOMs, right oil inlet 102 and right chamber 112 UNICOMs; Spool 110 is members that empty and its right ends is respectively equipped with left through hole 108 and right through hole 107 in; Spool 110 internal cavities are provided with horizontal spring 113; Spring 113 two ends respectively are provided with a spool ball 114 and offset with right through hole 107 with left through hole 108 respectively and block, and it is that converx hole communicates with the middle oil outlet 104 of valve body that spool 110 bottoms are provided with a vertical section; In chamber 111, a valve body left side, be provided with horizontal spring 115 and be against between left end rubbing surface of end cover and the spool left end lateral surface, and on the wall of the chamber in left chamber 111, be provided with jump ring groove 116, be provided with clamp in the jump ring groove 116.By also visible among Fig. 2, the spring pressure in the chamber, a regulation valve body left side is provided with elastic force plus-minus screw hole 117 on the left end end cap, can be used to install the elastic force plus-minus screw.The elastic force of the spring 113 in the valve core cavity is slightly larger than the elastic force of the spring 115 in the chamber, a valve body left side.
The structure of oil passage control valve 2 is identical with the structure of oil passage control valve 1.
When automobile under the cruising situation, promptly running car is in certain safe speed per hour scope, the lead limit switch that is installed under the Das Gaspedal is in open circuited state, promptly the electronics oil pump is not worked, but the power-transfer clutch on the car with the brake to work.When the driver steps down in pedal of clutch and brake pedal; Pressure oil in the fuel tank gets into from the left oil inleting port of oil passage control valve illustrated in figures 1 and 2; Left chamber through in the valve body enters into left oil outlet; Get into four-way piece again and enter into power-transfer clutch working barrel and the total working barrel of brake, power-transfer clutch and brake can simultaneously or be worked separately from total oil outlet.
When automobile in the cruising process, meet accident suddenly or emergency situation needs glancing impact, the driver since flurried mistaking accelerator for brake step on suddenly; Because Das Gaspedal is set in certain speed or the travel range by lead limit switch, at this moment, lead limit switch is switched on; The electronics oil pump is promptly started working, and at this moment, pressure oil is to the right oil inlet pump oil of oil passage control valve; Therefore the right cavity pressure in the valve body increases; Pressure overcomes the spring pressure in the chamber, a valve body left side, and spool is advanced left, and the interior clamp place of jump ring groove that spool is pulled to left chamber stops and just in time the left oil outlet of valve body sealed; The right oil outlet oil-feed that pressure oil has been connected with the right chamber of valve body to this moment; Come out to make power-transfer clutch work simultaneously automobile is become to brake rapidly from total oil outlet again, prevent the generation of accident with brake to fuel feeding of total working barrel while of power-transfer clutch working barrel and brake.
When automobile in the cruising process; Meet accident or emergency situation needs glancing impact suddenly; The driver is owing to flurried mistaking accelerator for brake is stepped on suddenly, when its left foot also steps down on the pedal of clutch simultaneously, when promptly the lead limit switch under pump clutch and the Das Gaspedal is worked simultaneously; At this moment the pressure oil in the fuel tank is from oil passage control valve left oil inleting port and right oil inlet left chamber in valve body and right chamber fuel feeding simultaneously; Pressure oil simultaneously from left oil outlet and right oil outlet to total oil outlet fuel feeding, oil outlet was again to total oil outlet fuel feeding in the middle of left through hole that pressure oil also can be through the spool right ends and right through hole enter into, at this moment power-transfer clutch works with brake simultaneously; Thereby realize the purpose of drag, the generation of stopping accident.
