Description of drawings
Fig. 1 is the theory structure scheme drawing of the embodiment of the invention.
Fig. 2 is the structural representation of the oil passage control valve among Fig. 1.
The specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, in the present embodiment, oil passage control valve 1 and oil passage control valve 2 are installed on the car body, as seen from the 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 entered 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, enters into power-transfer clutch working barrel 4, the total working barrel 6 of brake again after total oil outlet 206 of total oil outlet 106 of oil passage control valve 1 and oil passage control valve 2 comes out.Lead limit switch 8 is installed under the Das Gaspedal 9, and electronics oil pump 10 and electronics oil pump 11 are parallel on the lead limit switch 8.The oil inlet of electronics oil pump 10 and electronics oil pump 11 is connected with fuel tank 7, two oil outlet is 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, and introducing behind two oil passage control valves pressure oil more respectively by right oil inlet, the total oil outlet 106 and 206 from two oil passage control valves comes out to enter into respectively power-transfer clutch working barrel 4, the total working barrel 6 of brake.Be also shown in from figure, also be connected with by pass valve 12 and by pass valve 13 respectively between the oil outlet of electronics oil pump 10 and electronics oil pump 11 and fuel tank 7, be used for the oily flow of control oil circuit, 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; Described lead limit switch model is DEL1 * 1, and specification is LXJM1-9101; The model of described by pass valve is PB25B.
Referring to Fig. 2, it is the structural representation of the oil passage control valve 1 of present embodiment.As seen from the 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 two ends, left and right sides are 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 left through hole 108 and right through hole 107 respectively and block, and the hole that it is convex that spool 110 bottoms are provided with a vertical section communicates with oil outlet 104 in the middle of the valve body; 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 be provided with jump ring groove 116 at the chamber in left chamber 111 wall, be provided with clamp in the jump ring groove 116.By being also shown among Fig. 2, the spring pressure in the chamber, a regulation valve body left side is provided with elastic force at the left end end cap and adjusts screw hole 117, can be used to install elastic force and adjusts 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 normal travel situations, namely running car is installed in the state that lead limit switch under the Das Gaspedal is in disconnection in certain safe speed per hour scope, namely the electronics oil pump is not worked, but the power-transfer clutch on the car and brake will be worked.When the driver steps down in pedal of clutch and brake pedal, pressure oil in the fuel tank enters from the left oil inleting port of oil passage control valve illustrated in figures 1 and 2, enter into left oil outlet by the left chamber in the valve body, enter four-way piece again and enter into power-transfer clutch working barrel and the total working barrel of brake from total oil outlet, power-transfer clutch and brake can simultaneously or be worked separately.
When automobile in normal driving process, meet accident or emergency situation need brake the time suddenly, the driver is owing to flurried mistaking accelerator for brake is stepped on suddenly, because Das Gaspedal is set in the certain speed or stroke range by lead limit switch, at this moment, lead limit switch is switched on, the electronics oil pump is namely started working, 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, spool is advanced left, spool is pulled to the left oil outlet that clamp place in the jump ring groove in left chamber stops just in time valve body and seals, and the right oil outlet oil-feed that pressure oil was connected with the right chamber of valve body to this moment is come out to power-transfer clutch working barrel and the total working barrel of brake fuel feeding simultaneously from total oil outlet again, make power-transfer clutch work simultaneously automobile is become to brake rapidly with brake, prevent the generation of accident.
When automobile in normal driving process, meet accident or emergency situation need brake the time 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, be that lead limit switch under pump clutch and the Das Gaspedal is when working 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 and the right chamber fuel feeding in the valve body simultaneously, pressure oil simultaneously from left oil outlet and right oil outlet to total oil outlet fuel feeding, pressure oil also can enter into middle oil outlet again to total oil outlet fuel feeding by left through hole and the right through hole at two ends, the spool left and right sides, at this moment power-transfer clutch and brake worked simultaneously, thereby realize the purpose of drag, the generation of stopping accident.
