IDLER-ROLLER RECOIL DEVICE

IDLER-ROLLER RECOIL DEVISE An idler recoil device is utilized for track-type vehicles. The idler recoil device protects a crawler track system from damage when some foreign object, such as a rock, is trapped between an endless chain link assembly and a chain supporting element of the crawler track system. An idler link is pivotally connected to a track frame of the crawler track system and a recoilable rear idler is rotatably positioned on an idler hub itself pivotally connected to said idler link. An increase in tension on said endless chain link assembly causes said idler hub to rotate away from said endless chain link assembly decreasing track path length and, consequently, tension. This rotation is resiliently resisted by a recoil pad mounted between said idler hub and said idler link. A tensile link prevents any recoil up to a preselected endless chain link assembly tension.

ENDLESS TRACK SUSPENSION

An endless track suspension is comprised of a suspension support beam having an idler wheel assembly connected to a respective one of opposed ends thereof. At least one of the idler wheel assemblies has an endless track binding mechanism. Support wheels are secured to the suspension support beam and project from a lower face thereof. A drive sprocket is secured elevated above the suspension support beam by a support arm. The drive sprocket is secured to a vehicle drive axle by a coupling ring. The drive sprocket, the support wheels and idler wheels constitute an endless track support assembly for supporting an endless track in drivable engagement thereabout. A flexible connection of the drive sprocket support arm and the support wheels absorbs shocks and vibrations transmitted to the vehicle drive axle by the displacement of the endless track over a rough ground surface.

Snow vehicle track suspension

An improved snow vehicle track suspension employing a force-distributing mechanism comprising a swingarm, a three-arm bell crank, a connecting linkage, and a telescoping limiter linkage. The force-distributing mechanism apportions cushioning force from a shock absorber to track carriage components that bear upon a lower run of an endless-loop track to establish a desired weighting distribution of the track upon the surface of the snow. The force-distributing mechanism allows the track carriage to incline and decline within a limited angular range to enable the track to maintain tractional compliance with the surface of the snow.

Track tensioning system for a tracked vehicle

A suspension system for suspending an endless track beneath a tracked vehicle chassis. The suspension system can be a fully coupled suspension, a partially coupled suspension or a non-coupled suspension. The suspension system includes at least one elongated suspension rail having a front portion, a rear portion and a bottom track-engaging portion. At least one suspension arm has an upper end adapted for pivotal connection to the vehicle chassis and a lower end pivotally connected to the suspension rail. The lower end of the suspension arm can optionally have a displacement with a non-linear component. A biasing mechanism provides a biasing force to bias the suspension rail away from the vehicle chassis. The track tensioning system coupled to the suspension arm applies a tensioning force to the endless track in response to displacement of the suspension arm. The tensioning force generates a supplemental force transmitted by the endless track that augments the biasing force of the biasing mechanism. In a suspension system with front and rear suspension arms, the track tensioning system can be coupled to the front or rear suspension arms.

Rear suspension system for a land vehicle

A suspension assembly for mounting an endless track to a chassis of a snowmobile, the suspension assembly having a pair of pivoting arms centrally mounted to the slide members, or rails, and a weight transfer dynamic compensator capable of compensating for the weight transfer of the snowmobile when the track is pulling on the chassis. The weight transfer dynamic compensator prevents the chassis from rotating excessively with respect to the slide rails during rapid acceleration. Such a rotation of the chassis is detrimental to rider comfort and stability. The suspension assembly is coupled such the rails remain somewhat parallel to the chassis when encountering a bump at either the front of the rails or at the rear of the rails, also enhancing rider comfort and stability. The suspension assembly is coupled by virtue of a limited-translation slide bar at the rear of the suspension assembly and a tension-only member, or pulling belt, located at the front of the suspension assembly. The suspersion assembly having the weight transfer dynamic compensator improves the cornering of the snowmobile by ensuring that there is ample weight on the front skis, especially when accelerating out of a turn.

Drive belt suspension for snowmobile

An adjustment structure for the cushion unit of a snowmobile suspension system is provided. The adjustment structure includes a mounting for the cushioning unit that includes a bolt and a pair of mount brackets having guide apertures formed therein. Surfaces of the bolt and guide aperture are treated so as to avoid shifting of the mechanism under the weight of the snowmobile when the mounting bolt is loosened for adjustment.

Rear suspension system for a land vehicle

A rear suspension system for a land vehicle comprising a single generally centrally mounted structure in a middle portion of the rear suspension system. The suspension system comprises a pair of inclined primary suspension means, and a pair of inclined primary oscillating arms for pivotally connected to a pair of laterally spaced longitudinal slides at an underside area of the chassis of the land vehicle. Each of the primary oscillating arms comprise a distal end, which are further coupled to a horizontal bar adjacent a distal end of the primary suspension means, such as a shock absorber, and a proximal end which are individually mounted a horizontal bar adjacent a front end of the primary suspension means at an underside portion of the chassis. The suspension system further comprises a Weight Transfer Dynamic Compensator for raising a front tip portion of the longitudinal slides each time there is a transfer of weight in the vehicle. The Weight Transfer Dynamic Compensator is beneficial during acceleration and cornering of the vehicle by allowing the front end of the vehicle to remain close to the ground, thereby providing improved traction and control of the vehicle.

Elastic suspension device for tracked vehicles

Trunnion assembly

The trunnion assembly includes a housing and a one-piece tubular shaft journaled within bushings secured in the housing. Thrust forces acting on the shaft in one direction are counteracted by a spacer disposed between one bushing and a hub rigidly secured to the shaft. Thrust forces acting in the opposite direction are counteracted by a multi-segmented thrust ring fitted in a groove in the shaft in position to bear against another bushing in the housing. The thrust ring is held within the groove by a retainer ring disposed between the thrust ring and an annular lip of the housing. The retaining ring, the annular lip, and a seal retainer connected to the one piece shaft by a snap ring defines a seal ring cavity having a lubricant seal ring therein that is unaffected by axial thrust acting on the shaft and prevents leakage of lubricant between the shaft and the housing at the adjacent end of the shaft. The other end portion of the shaft is sealed to the hub and housing by a conventional seal ring. One end of a torsion bar is preferably received within and splined to the one-piece tubular shaft.
