Description
Technical field
The utility model relates to a kind of supercharging equipment, especially relates to a kind of turbosupercharger with circumferential venting function.
Background technique
The target of current motor is requirement low-speed big, this just requires turbosupercharger when low engine speed, when namely the motor unit time, air displacement was little, export larger energy, this just needs the circulation area of the turbine box in turbosupercharger less, could, under the condition of small flow, set up large expansion ratio like this.But, during high engine speeds, also there is high power requirements, too small circulation area is when high engine speeds, when namely the unit time, air displacement was large, too small circulation area can not meet exhaust requirements, this just needs bleed valve that a part of waste gas is directly entered to outlet pipe, and does not pass through turbine box.
Yet, existing common turbosupercharger as depicted in figs. 1 and 2, it comprises intermediate (bearing support) 1, turbine box 2 and be arranged at the turbine wheel 21 in turbine box 2, pressure shell 3 and be arranged at the compressor impeller 31 in pressure shell 3, rotating shaft 4 and bleed valve structure, turbine box 2 is attached to one end of intermediate 1, on the tank wall of turbine box 2, be provided with the bypass vent hole 23 being communicated with the waste gas runner 22 of turbine box 2, pressure shell 3 is attached to the other end of intermediate 1, rotating shaft 4 is rotatably arranged in the bearing unit 5 being contained in intermediate 1, turbine wheel 21 is connected in one end of rotating shaft 4, compressor impeller 31 is connected in the other end of rotating shaft 4, bleed valve structure comprises pressure valve 61, connecting rod 62, interlock crank 63 and venting valve 64, pressure valve 61 is installed on pressure shell 3 by valve mounting bracket 65, pressure valve 61 is connected with venting valve 64 with interlock crank 63 by connecting rod 62, venting valve 64 is placed on bypass vent hole 23.Can be by regulating the aperture size of the pressure change venting valve 64 of pressure valve 61 during this turbocharger operation, to realize the exhaust gas bypass of turbine box, but there is following problem in it: 1) due to venting valve processing problems and position problems, venting valve can only be done circular, therefore in order to cover bypass vent hole, bypass vent hole can only also be done circular (as shown in Figure 2), and be subject to the restriction of the waste gas runner position of turbine box, it is excessive that bypass vent hole can not be done, maximum diameter can only reach the width of waste gas runner, has so just limited discharge quantity; 2) because venting valve has hindered the proper flow of bypass waste gas when opening, thus waste gas bypass smoothly, waste gas will occur could bypass enter outlet pipe after significantly turnover, and this has just further affected discharge quantity; 3) because discharge quantity is very limited, therefore in large air displacement, can not emit on request enough waste gas, unnecessary waste gas has still passed through turbine box, and because the circulation area of turbine box is too small, when therefore unnecessary waste gas is by turbine box, turbine pressure can be suppressed to height, thereby will cause engine back pressure too high, and finally cause motor pumping loss excessive, engine power declines; 4) exhaust pressure that is motor due to the air pressure of waste gas, larger, so the active force that waste gas acts on venting valve can not be ignored, yet the variation due to opening angle and engine back pressure, the pressure acting on venting valve is often to change, so just make bypass waste gas from being up to the variation of minimum aperture, the control force of pressure valve is unsettled.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of turbosupercharger with circumferential venting function, and it is simple in structure, and can bypass go out enough waste gas.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of turbosupercharger with circumferential venting function, comprise turbine box and bleed valve assembly, on described turbine box, be provided with the waste gas outlet connecting flange being connected with the air discharging manifold flange of motor, on the tank wall of described turbine box, be provided with the bypass vent hole being connected with the waste gas runner of described turbine box, described bleed valve assembly comprises pressure valve, connecting rod and interlock crank, it is characterized in that described bypass vent hole is oblong, on the inner circle wall of described waste gas outlet connecting flange, be connected with circular rotatable air release plates and circular fixedly air release plates, in the rotatable air release plates of described circle, edge is circumferentially provided with the first venting through hole that a plurality of with described bypass vent hole is connected, described circle fixedly in air release plates along being circumferentially provided with a plurality of the second venting through holes, the first described venting through hole is corresponding with the position of the second described venting through hole, between the rotatable air release plates of described circle and described interlock crank, be provided with the driving mechanism that drives the rotatable air release plates of described circle to rotate.
In described waste gas outlet connecting flange, be wholely set vertically turbine exhaust discharge tube, space between the periphery wall of the inner circle wall of described waste gas outlet connecting flange and described turbine exhaust discharge tube forms the exhaust gas bypass chamber being connected with described bypass vent hole, described exhaust gas bypass chamber is connected with the first described venting through hole, the rotatable air release plates of described circle and described circle are fixedly provided with center hole in air release plates, the center hole of the described rotatable air release plates of circle and described the circle fixedly periphery wall of the hole wall of corresponding and two center holes of the central hole location of air release plates and the outside axle head of described turbine exhaust discharge tube are close to, at this, turbine exhaust discharge tube is not only for discharging turbine exhaust, and for supporting circular rotatable air release plates and circular fixedly air release plates.
