Description

EXHAUST VIBRATION DAMPER
TECHNICAL FIELD
The present disclosure relates to an exhaust vibration damper. Particularly, but not exclusively, the disclosure relates to a damper using an exhaust trim. Aspects of the invention relate to a motor vehicle exhaust vibration damper, a motor vehicle exhaust system, and to a motor vehicle.
BACKGROUND
There are two main factors contributing to vibration within the exhaust system of motor vehicles: power unit excitation and road load inputs. In order to provide an improved driver and passenger experience, there is a need to dampen the vibrations within the exhaust system of motor vehicles. However, the vibration effect may be exacerbated due to structural resonances which are dependent upon each specific exhaust system arrangement. To address the problem of exhaust system structural resonances, prior art solutions have added tuned frequency dynamic absorbers to the exhaust system. These palliatives by their nature and function add significant weight to the exhaust system.
The present invention aims to address one or more of the above problems.
SUMMARY OF THE INVENTION
Aspects and embodiments of the invention provide a motor vehicle exhaust vibration damper, a motor vehicle exhaust system, and a motor vehicle as claimed in the appended claims.
According to an aspect of the invention, there is provided a motor vehicle exhaust vibration damper comprising: an exhaust trim and a resilient mounting; wherein: the resilient mounting is configured to connect the exhaust trim to a tailpipe of a motor vehicle so as to provide a damped spring-mass system where the exhaust trim is the mass and the resilient mounting is the spring.
Variation of the resilient mounting geometry will vary the tuned frequency of the resultant dynamic absorber. Variation of the resilient mounting compound will vary the tuned frequency of the resultant dynamic absorber.
The mass of the exhaust trim may be altered by providing and connecting an alternate exhaust trim. The mass of the bracket may be altered by providing and connecting an alternate bracket. The mass of the resilient mounting may be altered by providing and connecting an alternate resilient mounting.
By resiliently mounting the mass of the tailpipe trim, rather than rigidly fixing as in the prior art, the function of a dynamic absorber may be effected. Furthermore, by using the exhaust tail pipe trim mass as the oscillating mass, the solution utilises a mass that already exists on the system, rather than the need to add more mass as would result in the fitment of a discrete device.
The exhaust trim may be a decorative exhaust trim.
The resilient mounting may further comprise a bracket configured to rigidly mount the damper to the tailpipe of the motor vehicle.
The resilient mounting may comprise an elastomeric element having intrinsic/natural damping.
The elastomeric element may be arranged between the bracket and the exhaust trim. The bracket acts as a heat shield in use.
The elastomeric element may be connected to the exhaust trim by an elastomeric weld.
The elastomeric element may be annular.
The resilient mounting may comprise a single annular elastomeric element.
The resilient mounting may be a plurality of elastomeric elements.
The plurality of elastomeric elements may be arranged about an inside surface of the exhaust trim.
The elastomeric element may be made of silicon rubber or ethylene propylene diene monomer rubber or ethylene acrylic elastomer.
The resilient mounting may be one of a leaf spring or a coil spring and a damping means.
The tailpipe may terminate in a distal end, and wherein the bracket is arranged at or adjacent to the distal end of the tailpipe.
According to another aspect of the invention, there is provided a motor vehicle exhaust system comprising: a tailpipe; and the motor vehicle exhaust vibration damper as hereinbefore described, wherein one of: the mass of the exhaust trim, the mass of the resilient mounting, the axial position of the damper relative to the tailpipe, the axial position of the exhaust trim relative to the tailpipe, the stiffness of the resilient mounting, the geometry of the resilient mounting, is predetermined based upon the vibration characteristics of the motor exhaust system in use, so as to provide a tuned motor vehicle exhaust vibration damper.
Variation of the resilient mounting geometry will vary the tuned frequency of the resultant dynamic absorber. Variation of the resilient mounting compound will vary the tuned frequency of the resultant dynamic absorber.
The mass of the exhaust trim may be altered by providing and connecting an alternate exhaust trim. The mass of the bracket may be altered by providing and connecting an alternate bracket. The mass of the resilient mounting may be altered by providing and connecting an alternate resilient mounting.
According to yet another aspect of the invention, there is provided a motor vehicle comprising the motor vehicle exhaust vibration damper as hereinbefore described.
According to a further aspect of the invention, there is provided a method of assembling a vibration damper for motor vehicle exhaust system comprising: providing an exhaust trim; providing a resilient mounting; connecting the exhaust trim to a tailpipe of a motor vehicle exhaust system via the resilient mounting so as to provide a motor vehicle exhaust vibration damper comprising a damped spring-mass system where the exhaust trim is the mass and the resilient mounting is the spring.
The method may further comprise providing a bracket and rigidly mounting the damper to the tailpipe of the motor vehicle.
The resilient mounting may comprise an elastomeric element having natural damping wherein the bracket is elastomerically welded to the resilient mounting.
The resilient mounting may comprise an elastomeric element having natural damping wherein the exhaust trim is elastomerically welded to the resilient mounting.
According to a further aspect of the invention, there is provided a method of tuning a motor vehicle exhaust system comprising assembling a vibration damper in accordance with the method of assembly defined above, and further comprising altering at least one variable. The at least one variable may comprise one or more of a mass of the exhaust trim, a mass of a bracket used to attach the damper to the tailpipe, a mass of the resilient mounting, an axial position of the bracket relative to the tailpipe, an axial position of the exhaust trim relative to the tailpipe, a stiffness of the resilient mounting, a geometry of the resilient mounting, and a geometry of the bracket.
