Background technique
The main effect of automotive air intake system is to motor provides clean air, and effectively reduces noise.Because vibration, the installation precision of motor and problem such as expand with heat and contract with cold, being connected between motor and the air-strainer can not be rigidity, needs flexible pipe.(patent No.: 200920225282.X), by titanium dioxide and TPE material mixing blow moulding and forming, be bellows, efficiently solve the blowing wall thickness problem of TPE material, damping effect is better to have occurred a kind of empty filter connection engine charge flexible pipe at present; But when automobile accelerates or go up a slope, easily suction tude is inhaled flatly, therefore a kind of engine air inlet tube (patent No.: 200920225282.X), adopt the double-ply bellows structure that has enhancement layer has appearred in the air feed deficiency.In the motor breathing process, gas handling system can produce resonance noise level radiated noise, even causes vibration, influences the overall comfort of automobile.Along with the raising that in the world automobile emission and noise reduction is required, the noise reduction of air filter for automobile has caused people's attention, a kind of noise control type air induction hose (patent No.: 200410000419.3), comprise that an air induction hose, are formed on a part of flexible pipe widening parts of air induction hose, and are formed on inner cover in the flexible pipe widening parts, and are formed on the spacing wall that obtains the closed area between flexible pipe widening parts and the inner cover and and stretch out from inner cover and make the inboard inner flexible tube with the closed area interconnection of air induction hose has appearred; The length of control inner flexible tube can effectively reduce low frequency and high-frequency noise, but complex structure.
In order to ensure unimpeded the connection and reasonable Arrangement between motor and the air-strainer, effectively reduce the noise of gas handling system, the utility model proposes a kind of motor car engine helical silencing air induction hose.
Summary of the invention
The purpose of this utility model is effectively to reduce the noise of automotive air intake system; Improve the flow guide structure of engine air inlet tube, strengthen intake swirl, increase air mass flow.The utility model can be used for all kinds of general cars, passenger vehicle, cargo vehicle and special car, as engineering automobiles, agricultural automobile and race engine etc., also can be used for other reciprocating machines.
The utility model comprises tube wall skin (1), tube wall internal layer (2), tube wall stiffening rib (3), baffle (4), suction port connecting body (5), main pipe (6) and air outlet connecting body (7), and is represented as Fig. 1.Described main pipe (6) has the double-deck hollow bellows structure of band tube wall stiffening rib (3), and tube wall skin (1) and tube wall internal layer (2) all adopt the elasticity sound absorbing material, effectively sound-absorbing, noise reduction and sound insulation.
Described tube wall skin (1) only closely is connected with tube wall stiffening rib (3) in main pipe (6) part, has cavity between tube wall skin (1) and tube wall internal layer (2); Also closely be connected with tube wall internal layer (2) with air outlet connecting body (7) part at suction port connecting body (5).Described tight connection comprises welding, hot pressing and bonding at least.
Described tube wall stiffening rib (3) cross section is circular, closely is connected with tube wall internal layer (2) with tube wall skin (1); Employing is guaranteed the bulk strength of tube wall than the material of high-strength tenacity, prevents to inhale flat phenomenon.
Described baffle (4) closely is connected with tube wall internal layer (2), be that cross section is the prismoid of parallelogram, along evenly distributing with the helix of main pipe (6) center line angle less than 45 °, can avoid the air blast of crossing of tube wall internal layer (2) is impacted fluctuation, the intake swirl of reinforcing stimulus increases air mass flow.The long limit of described parallelogram is consistent with helix direction, and minor face is consistent with the centerline direction of tube wall stiffening rib (3).
The beneficial effects of the utility model are: adopt the double-deck hollow bellows structure of band tube wall stiffening rib, tube wall skin (1) and tube wall internal layer (2) all adopt the elasticity sound absorbing material, effectively sound-absorbing, noise reduction and sound insulation; The tube wall stiffening rib adopts the material than high-strength tenacity, guarantees the bulk strength of tube wall, prevents to inhale flat phenomenon; The baffle (4) of tube wall internal layer (2) inboard is avoided the air blast of crossing of tube wall internal layer (2) is impacted fluctuation along evenly distributing with the helix of main pipe (6) center line angle less than 45 °, and the intake swirl of reinforcing stimulus increases air mass flow.The utility model is not only guaranteed reasonable Arrangement and unimpeded connection the thereof of motor and air-strainer, effectively reduces the noise of gas handling system, and has improved the flow guide structure of suction tude, and is simple in structure.
