Description

A kind of motor silencer
Technical field
The utility model belongs to engine exhaust technical field, especially relates to a kind of motor silencer.
Background technique
Along with people's growth in the living standard, the social recoverable amount of Motor Vehicle increases gradually, motor is the required parts of Motor Vehicle, need by baffler exhausting air in engine working process, the baffler of existing motor, generally adopt suction tude and outlet pipe to be all deep in baffler to interlock, suction tude and outlet pipe are provided with pore, this structure can reach certain erasure effect, but its exhaust resistance is larger, affect the Power output of motor, oil consumption simultaneously and blowdown flow rate also improve thereupon, along with the raising of the requirement limited engine noise, the baffler of this structure can not meet the needs of people.
Summary of the invention
The purpose of this utility model be to improve the deficiency of prior art and provide a kind of and reduce engine exhaust speed, prevent from baffler from resonating producing noise, multistage noise reduction, structure is simple, air resistance is little, improve engine power, motor silencer that using effect is good.
The purpose of this utility model realizes like this, a kind of motor silencer, by housing, suction port and air outlet composition, be characterized in being provided with sound-insulating cover in housing, the two ends of sound-insulating cover communicate with suction port and air outlet respectively, the insulation board with taper air outlet hole is provided with in sound-insulating cover, the upper conical air outlet hole of insulation board is greater than the diameter near air outlet side near the diameter of air inlet side, sound-insulating cover is provided with taper air outlet hole, the inside diameter of the taper air outlet hole wherein on the anterior sound-insulating cover of insulation board is greater than outside diameter, the inside diameter of the taper air outlet hole on the sound-insulating cover of insulation board rear portion is less than outside diameter.
In order to realize the purpose of this utility model further, can be, with the acoustical panel of taper air outlet hole, the cavity formed between housing and sound-insulating cover is divided into two-part, the upper conical air outlet hole of acoustical panel be greater than the diameter near air outlet side near the diameter of air inlet side.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is provided with sound-insulating cover in housing, the two ends of sound-insulating cover communicate with suction port and air outlet respectively, the insulation board with taper air outlet hole is provided with in sound-insulating cover, the upper conical air outlet hole of insulation board is greater than the diameter near air outlet side near the diameter of air inlet side, sound-insulating cover is provided with taper air outlet hole, the inside diameter of the taper air outlet hole wherein on the anterior sound-insulating cover of insulation board is greater than outside diameter, the inside diameter of the taper air outlet hole on the sound-insulating cover of insulation board rear portion is less than outside diameter, the waste gas part that such motor is discharged is slowed down by the pore on sound-insulating cover and is discharged between housing and sound-insulating cover, this avoid the noise that high-speed exhaust gas directly clashes into housing generation, another part waste gas is under the stop of insulation board, speed reduces greatly, reduce high-speed exhaust gas and be directly discharged to noise in air, the opening direction of taper air outlet hole is arranged according to the flow direction of air-flow, the diameter of suction port is greater than the diameter of air outlet, be convenient to air-flow by and significantly flow velocity, the effect that gaseous exchange is mutual, avoid high-speed exhaust gas to clash and shake the noise of generation, with taper air outlet hole, the cavity formed between housing and sound-insulating cover is divided into two-part by acoustical panel, the upper conical air outlet hole of acoustical panel is greater than the diameter near air outlet side near the diameter of air inlet side, because the exhaust gas velocity of suction port end is the highest, adopt this structure gas distribution at a high speed can be slowed down, further avoid the noise clashing into and produce.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is another kind of structural representation of the present utility model.
Specific embodiments
Embodiment 1, a kind of motor silencer, with reference to Fig. 1, a kind of motor silencer, be provided with sound-insulating cover 5 in housing 1, the two ends of sound-insulating cover 5 communicate with suction port 2 and air outlet 3 respectively, the insulation board 6 with taper air outlet hole 4 is provided with in sound-insulating cover 5, the diameter of the upper conical air outlet hole 4 of insulation board 6 near suction port 2 side is greater than the diameter near side, air outlet 3, sound-insulating cover 5 is provided with taper air outlet hole 4, the inside diameter of the taper air outlet hole 4 wherein on the anterior sound-insulating cover 5 of insulation board 6 is greater than outside diameter, the inside diameter of the taper air outlet hole 4 on insulation board 6 rear portion sound-insulating cover 5 is less than outside diameter, which constitute a kind of structure of the present utility model.
Embodiment 2, a kind of motor silencer, with reference to Fig. 2, on the basis of embodiment 1, be, with the acoustical panel 8 of taper air outlet hole 4, the cavity formed between housing 1 and sound-insulating cover 5 is divided into two-part, the diameter of the taper air outlet hole 4 on acoustical panel 8 near suction port 2 side is greater than the diameter near side, air outlet 3.Other are identical with embodiment 1.
When using the utility model, suction port 2 of the present utility model is communicated with the relief opening of motor, the high-speed exhaust gas that motor produces, enter in sound-insulating cover 5 by suction port 2, a part is through the taper air outlet hole 4 of insulation board 6, another part enters between housing 1 and sound-insulating cover 5 by the taper pore 4 on sound-insulating cover 5, slowed down by the acoustical panel 7 of band taper air outlet hole 4, and then get back in sound-insulating cover 5, during arrival air outlet 3, two-part gas converges, then discharge, because gas is through slowing down, very low in discharge hourly velocity, thus there is no noise.
