<p>A vehicle (10) capable of high speed operation over rough terrain has a suspension system (17) including an elevated drive wheel (18), a front idler wheel (24), and a rear idler wheel (26) with an elastomeric drive belt (22) entrained therearound. The drive belt (22) is driven by friction, and the suspension system includes a front suspension strut device (48) having a recoil mechanism (106) and a resilient front strut (50) that resiliently biases the front idler wheel (24) forwardly and downwardly. A braking device (39) is in a protected location within side portions (32, 34) of the front idler wheel (24) and reacts against the front suspension strut device (48) to brake the vehicle. Such braking reaction minimizes the reduction of frictional engagement between the drive wheel (18) and the drive belt (22) due to the reaction of the drive belt (22) against the recoil mechanism (106) when traveling forwardly.</p> |
