Technical field
The utility model relates to a kind of venting gas appliance of blast duct for vehicle, is meant especially a kind ofly can control air displacement, deflation rate, and then has the device of control engine torsion, horsepower output etc.
Background technique
Traditional vehicle exhaust pipe is a simple metal tube.As shown in Figure 1, be the cross-sectional schematic of outlet pipe in the prior art.This outlet pipe is because the caliber of outlet pipe is fixed, and venting capacity also has been fixed.But vehicle in the process of moving, needs bigger exhaust resistance when engine speed is low, in order to avoid inflammable mixture also just is not discharged from by clean-burning the time; And when motor is high-revolving, needing exhaust smooth and easy as far as possible, the short time can be discharged waste gas as much as possible more, in order to avoid cause the resistance to the engine piston high speed activities.Fixedly the outlet pipe of caliber is to take into account this 2 point, present car manufactures can only be got its mean value, perhaps adopt corresponding outlet pipe design according to its vehicle orientation, in racing car is produced, be topic in order to solve this, can adopt bigbore outlet pipe when racing car is produced, even use 2 even 4 outlet pipes, to improve the exhaust smooth degree, give full play to the horsepower output of sport car when high rotating speed.But these measures all can not realize the exhaust size according to the needs of engine rotation from basic realization, and then play the effect of control engine torsion, horsepower output.
The model utility content
Shortcoming at above-mentioned prior art existence, the purpose of this utility model is to provide a kind of and is installed in the blast duct for vehicle, to the demand of gas emissions size, control the effective venting gas appliance of vehicle exhaust of discharge amount of exhaust gas, drainage rate according to motor in the vehicle driving process.
The technical solution adopted in the utility model is: the effective venting gas appliance of a kind of vehicle exhaust, it comprises circular valve spoiler, coupling shaft, stepper motor and central control unit, described valve spoiler is arranged in the outlet pipe, described valve spoiler is fastened on the described coupling shaft, described coupling shaft passes and is connected with the output shaft of described stepper motor by bearing from exhaust wall, described stepper motor is connected with described central control unit by signaling line, and the tach signal line of vehicle motor is connected with described central control unit.
Described valve spoiler is fixed on the middle part of described coupling shaft, and the lower end of described coupling shaft passes from exhaust wall, and the tube wall of the upper end correspondence of described coupling shaft can be embedded with bearing, and the upper end of described coupling shaft is arranged in the described bearing.
Described valve spoiler is fixed on the middle part of described coupling shaft, and the lower end of described coupling shaft passes from exhaust wall, can have the axis hole groove on the tube wall of the upper end correspondence of described coupling shaft, and the upper end of described coupling shaft is arranged in the described axis hole groove.
Described valve spoiler can be connected and fixed by bolt and described coupling shaft.
Described valve spoiler can be fixing with described coupling shaft welding.
The effective venting gas appliance of vehicle exhaust of the present utility model, because the tach signal line of vehicle motor is connected with described central control unit, central control unit is connected with stepper motor by signaling line, the step motor control coupling shaft, coupling shaft is fixedly connected with the valve spoiler that is arranged in the outlet pipe, like this, central control unit is when obtaining engine rotational speed signal, according to engine speed, control exhaust pipe device valve spoiler folding angle, thus the size of control air displacement increases or reduces resistance, realization is to the control of engine exhaust resistance, satisfies the vehicle needs that motor constantly changes exhaust resistance when different rotating speeds that are in operation.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
