Description

Vehicle exhaust pipe fixing device and vehicle

Technical field

This utility model relates to vehicular field, especially relates to the fixing dress of a kind of blast duct for vehicle Put and vehicle.

Background technology

Gas extraction system refers to collect and discharge the system of waste gas, including exhaust manifold, exhaustor, Go out sound tube, tail pipe and resonator, and three schools generally controlling electromotor pollutant emission are urged Changing device to be also mounted in gas extraction system, exhaustor generally comprises front exhaust pipe and heel row trachea. Usually, exhaustor is suspended on vehicle frame by aerofluxus hanging

In motion, the vibration of dynamical system is delivered to aerofluxus by gas extraction system and links up with vehicle, Then being transferred to vehicle frame by aerofluxus hook, this vibration makes the passenger in car and driver produce Raw discomfort, meanwhile, self mode of oscillation, the gas flowing of gas extraction system are hindered by this vibration Power, wave noise all can produce impact, directly affect gas extraction system overall performance, indirectly make About engine performance promotes, and makes electromotor later stage dynamic property, economy promote and is directly limited System.

As can be seen here, for the transmission of the vibration that decays, erecting by overhang is needed to possess good subtracting Shake function.At present, most erecting by overhang uses block rubber to carry out vibration damping, the one of block rubber End is connected with vehicle frame, and the other end is connected with exhaustor.Also have some erectings by overhang by support and Block rubber is formed by connecting, and support uses metal to make, and support is connected with vehicle frame, and support plays Support exhaustor and retrain the effect of block rubber.

But these erectings by overhang above-mentioned are single-stage vibration-proof structure, only rely on the bullet of block rubber Property carry out vibration damping, effectiveness in vibration suppression is poor so that be transferred to the vibration of vehicle frame relatively big, the passenger in car Poor with the comfort level of driver.

Additionally, aerofluxus hook is the installing hole through erecting by overhang, prior art only depends on Elasticity by block rubber fixes aerofluxus hanging, but, when vehicle moves, aerofluxus is linked up with Can slide along the axial direction of installing hole, cause the contact position mill of aerofluxus hook and erecting by overhang Damage, reduce the service life of erecting by overhang.
