Abstract
An accumulator for accommodating changes to the operating medium's volume in a suspension system for a leanable vehicle, the suspension system having dampers associated with a pair of laterally spaced wheels wherein the dampers have associated control means operable to cause the dampers to operate either independently or simultaneously. The accumulator's resistance means may be a coil spring, spring washer, compressed gas or compressible closed cell. The operating medium may be separated from the resilience means by a diaphragm, bladder or piston.
Description
Accumulator This invention relates directly to the Suspension System that is described in PCT/GB2007/004630 unless otherwise stated.
In PCT/GB2007/004630 an innovative Suspension System is described. This Suspension System comprises several components. Some of the said components define an internal volume/s. In at least one embodiment of the Suspension System the said internal volume/s is filled with a fluid operating medium. A change in the said medium's temperature is also likely to change the said medium's volume. If the said internal volume cannot sufficiently compensate for the said medium's change in volume a hydraulic lock may occur. The invention is the means by which the said hydraulic lock may be avoided.
The invention is the addition of at least one accumulator connected to the said internal volume/s. The accumulator can be of a bladder, diaphragm, or piston construction.
These three accumulators can each be pressurised by either a gas or mechanical spring. The operation of the said accumulators will be familiar to anyone practiced in the art. Consequently there is no need for a detailed explanation of how the said accumulator works, except that the mechanical spring can alternatively be of a Disc Spring washer type.
Alternatively, an accumulator mechanism could be achieved by a material comprising one or more closed cells. The said material would be contained in a chamber that is open to the said internal volume/s and acted upon by the said medium. When the said medium's pressure increases, the said material reduces its volume by the compression of the said material's closed cell/s. When the said medium's pressure decreases, the said material's volume increases by the decompression of the said material's closed cell/s. Thereby, the said material compensates for volume changes to the said medium. The said material would have to be designed to reduce and increases its volume at the desired pressures and rates applicable to the particular application. The said material would have to be designed to last for a desired duration of service whilst being continually immersed in the desired said medium. The said material would also have to be designed to last for a desired duration of service whilst being continually subjected to temperature and pressure changes.
In a further embodiment of the invention the said material could be integral to the said components such as the interconnecting pipes in PCT/GB2007/004630. The said material is not restricted to being used in the said internal volume/s because the said material could also be used in many other hydraulic circuits where a said accumulator is required. The said material would be a very cheap alternative to the said accumulators. Closed-multi-cell materials are used in many non hydraulic applications. Closed-multi-cell materials are commonly available in large sheets.
These sheets differ in their thickness, density, and ability to withstand contamination from different fluids. It would not be an expensive exercise to use existing closed-multi-cell manufacturing processes to manufacture the said material.
The invention will be further described by way of diagrams whereby:

Figure 1 * Shows one embodiment of the Suspension System described in Figure 2 Shows Figure 1 with one embodiment of the invention.
Figure 3 Shows a cross section of a compressible closed-multi-cell material acting as an accumulator without sufficient pressure to compress the closed-multi-cell material in a purpose built chamber open to the said internal volume.
Figure 4 Shows Figure 3 but with sufficient pressure to compress the closed-multi-cell material.
Figure 5 Shows a cross section of a compressible closed-single-cell material acting as an accumulator without sufficient pressure to compress the closed-single-cell-material in a purpose built chamber open to the said internal volume.
Figure 6 Shows Figure 5 but with sufficient external pressure to compress the closed-single-cell material.
Figure 7 Shows Figure 3 but with the said interconnecting pipe replacing the said chamber.
Figure 8 Shows Figure 4 but with the said interconnecting pipe replacing the said chamber.
