Embodiment Construction

[0042] The following description and drawings relate to example tuned mass damper assemblies and methods for damping vehicle vibrations. The assembly and method utilizes an existing vehicle mass (eg, a spare tire) as the tuning mass for the assembly. The present disclosure teaches a spare tire damper assembly that may be attached to a vehicle chassis. The damper assembly is used to absorb occasional vibrations of the vehicle's suspension and reduce the amplitude at the occupant's position. The mass of the spare wheel and the subframe attached to the spare wheel, when adjusted to coincide with the first vertical bend of the vehicle, greatly reduces the magnitude of the first bend response by absorbing vibrations. The damper assembly includes an adjustable damping mechanism so that the damper assembly can be adjusted after assembly. The damping mechanism or vibration isolator is adjustable in the sense that the height and associated masses of the damping mechanism or vibration...

Abstract

The invention provides a spare tire damper assembly for a vehicle, comprising: a support frame configured to fix a spare tire; a first isolator disposed relative to the support frame, the first isolator being configured to be adjustable in at least one direction; and A second isolator, in series with the first isolator so that adjustment of the first isolator can adjust the static preload of the second isolator. A mass damper assembly for a vehicle is also provided, comprising: a mass; a link configured to secure the mass to the vehicle; a first isolator disposed relative to the mass and adjusted according to pneumatic control. The invention can adjust the vehicle for different situations.

Description

technical field [0001] The present invention generally relates to assemblies and methods for reducing vibration of a vehicle utilizing a different mass damper, such as a spare tire. Background technique [0002] It is relatively common to use mass dampers to improve the ride of a vehicle. A mass damper is connected to the vehicle frame and is tuned to resonate at a predetermined frequency in order to dampen vibrations of the vehicle. Due to the low resonant frequencies of the frame and rear axle modes of the truck, the truck tends to be more sensitive to vertical vibrations. Many utility trucks exhibit uncomfortable vertical ride vibrations caused by the road. These high levels of vibration are caused by the interaction between the vehicle's first bending mode and the rear axle bounce mode. Typically, the spare wheel assembly in trucks and sport utility vehicles (SUVs) is rigidly connected to the vehicle's underframe. However, many damper designs include the use of a dev...
