These are connected middle-to-back on each side but not through the transaxle. That is, each middle wheel is connected to its rear wheel, but the left side is not connected to the right side.<br /><br />The suspension limits are limits on the angles through which these two basic parts (the rockers and the bogies; we unfortunately can't distinguish the left from the right bogies) are allowed to articulate. For example, we might say that the differential (the amplitude of the articulation of the rockers) is allowed to go up to five degrees, while the bogies can range from -8 to +10 degrees. (All angles are chosen such that a vehicle at rest on a flat table would have zero for all measurements.)<br /><br />Since the suspension articulates in characteristic ways as we climb obstacles, well-chosen settings for the suspension limits are often our first line of defense against climbing something that's larger than we expect.Scott Maxwellhttps://www.blogger.com/profile/11510688120932625522noreply@blogger.comtag:blogger.com,1999:blog-5557240086320000561.post-82288739685336947312011-02-08T14:12:03.456-08:002011-02-08T14:12:03.456-08:00Hi,

If you ever explain them I've missed it.Anonymoushttps://www.blogger.com/profile/06036930141564775566noreply@blogger.com
