摘要： A tracked vehicle of narrow aspect suitable for unmanned operation both in hazardous environments and on routes normally accessible only to pedestrians, comprises two identical vehicle units (1, 2) each having an independently drivable, full width track (3), the units being interconnected in tandem configuration by an articulation mechanism (9) permitting relative rotation about a yaw axis (Y). In one aspect the articulation mechanism is passive, being arranged with an offset yaw axis, thereby permitting steering by application of a velocity differential to the two tracks. In a second aspect the articulation mechanism is active being powered by an actuator (94) to provide articulation steering. The articulated units may also be secured in parallel configuration for conventional skid-steering operation.

摘要： A track-laying vehicle of the type which has an engine, transmission, opeors cabin, running wheels and tracks which extend around the running wheel, has a compound support structure consisting of a torsionally rigid, generally planar rectangular chassis frame which carries the enigne, the transmission and the operator's cabin. The running wheels and tracks, by contrast, are mounted upon a wheel-carrying frame and is substantially coextensive with an underside thereof. The wheel-carrying frame is torsionally compliant and is connected to the chassis frame by a plurality of elastic journals.

摘要： A suspension system for a track driven vehicle such as a snowmobile, which has a vehicle body and a rigid frame, the suspension system pivotally interconnecting the body with the frame and comprising spaced front and rear support frames. The front support frame carries front torsion spring members having spring arms extending longitudinally along the rigid frame, each front torsion spring means having a spring arm engaging a cam surface on the rigid frame to vary the effective length of the torsion spring arm, the torsion spring arm being engageable with a cam edge of selected configuration to provide a desired progressive spring rate response to vertical displacement of the vehicle body with respect to the rigid frame. The rear support frame similarly includes torsion spring members each having spring arms for engagement with cam surfaces carried by the rigid frame to vary the effective length of the spring arm, the spring arm being engageable with a cam edge of selected configuration to provide a progressive spring rate during vertical displacement of the vehicle body with respect to the rigid frame. The rear support frame is pivotally connected to the rigid frame through side link members, one end of each link member having a pivotal connection with the rigid frame and the other end of each link member having a pivotal connection to a transverse member of the rear support frame. This transverse member is provided at a transverse axis of a bell crank lever system comprising a crank arm which is pivotally interconnected to a piston-cylinder shock absorber means carried by the rigid frame. The axis of the lower transverse member of the rear support frame is movable in an arc determined by the side links connecting the axis to the rigid frame and provides a movable, floating axis for the rear support frame to not only increase vertical displacement of the vehicle body but to also facilitate a selected progressive spring rate in the resilient suspension of the rear support frame.

摘要： A suspension device for motor driven vehicles such as snowmobiles comprises a pair of slide rails which are resiliently suspended under the vehicle body to ensure engagement of the ground-engaging portion of a flexible endless track with the ground, the endless track being driven by a drive sprocket wheel journalled on the front portion of the vehicle body and stretched at its rear portion over rear idler wheels journalled on the rear portions of the slide rails. The resiliency of the suspension device is adjusted to prevent skidding of the rear portion of the endless track.

摘要： Vehicle track support means comprising laterally spaced rollers underlying the return run of the track to absorb vertical track forces. Wear plates are disposed between the rollers to engage side surfaces of the track teeth, thereby preventing lateral dislocation of the track. In a preferred arrangement the wear plates are readily replaced without disturbing the rollers, and vice versa.

摘要： The disclosure herein describes a slide rail for use in a snowmobile-type suspension assembly; the rail consists of an elongated member with a bottom wall and two side walls. Each side wall is provided with a pair of longitudinally spaced slots, one slot of one side wall being transversely aligned with a slot of the other side wall. The elongated member is mounted to a bearing shaft transversely extending beneath the vehicle, by means of separate link members with one end pivotally mounted on the shaft and with the other end adjacent the slots, of fastening members extending through the slots and securing the lower ends of the link members, and of torsion spring means which are supported on the bearing shaft and include end portions in yielding engagement with link members disposed fore and aft relative to the bearing shaft and urging the link members in a downward direction to thereby cause the rail to maintain contact pressure on the lower run of the track.

摘要： A suspension for traction belt driven vehicles in which each arm of the suspension is permitted to deflect independently of the remaining arms. Movement of the suspension arms about a common pivot shaft is resisted by elastomeric torsion springs attached to the ends of the suspension arms surrounding spaced axial portions of the pivot shaft such that the arms extend in cantilevered arrangement from the shaft. Idler pulleys are rotatably attached to the free end of each arm for contacting the running traction belt.

摘要： A track suspension means for vehicles having endless track drive and support surfaces, the vehicle having frame means with forward and rear mounting points. The track suspension means which is coupled to the vehicle at the mounting points includes longitudinally flexible leaf spring means, the leaf spring means having an axis disposed generally parallel to the track axis, and being adapted to flex vertically. The leaf spring, which carries a plurality of supporting means for the track, is secured at its forward end to the vehicle frame at the forward mounting point. The endless track suspension means includes forwardly and rearwardly disposed sprockets inscribed within the endless track, and mounting means are provided for the sprockets including mounting shafts. Track propelling means are coupled to the forwardly disposed sprockets, and track tensioning means and the rear of said leaf spring are operatively coupled to the rearwardly disposed sprockets. Pivot linkage means are provided for coupling the rear sprocket mounting means to the vehicle at the rear mounting point. The pivot linkage means includes a first arm pivotally coupled to the vehicle mounting point and with a floating pivot shaft journaled to the other end of the first arm. A second arm is provided having one end journaled to the floating pivot, and with the other end coupled to the rear sprocket mounting means. Resilient spring bias means are coupled to the second arm and normally urge the mounting shaft means for the rearwardly disposed sprockets in a direction toward the lower span of the endless track.

摘要： In a motor sledge having a supplementary frame extending from the rear end of the frame construction and flexibly pivoting around a horizontal axis the slackening of the common drive belts due to upward movement of the supplementary frame is prevented by a pair of rolls freely rotatable above the point of pivotement. When the supplementary frame pivots upwardly the upper surface of the drive belts are pressed against the rolls.

摘要： A suspension system for a tracked vehicle including a unitary suspension frame with track wheels mounted thereon for engagement with the lower run of the drive track. Idler means mounted on the rear end of the suspension frame support the rear end of the drive track. Spring means are provided to support the vehicle body on the suspension frame. The spring means are connected such that a predetermined amount of longitudinal relative movement is permitted between the suspension frame and the body. A rearwardly and downwardly sloping control arm is pivotally connected between the body and the front end of the suspension frame so that the forwardly located track wheels are forced downwardly by the control arm when the suspension frame moves forwardly with respect to the body.
