Convertible carrier // 2489293

FIELD: transport.

SUBSTANCE: invention relates to convertible carrier that adapts to different relief features to overcome different obstacles. Proposed carrier comprises wheel 1 and system of levers with rolls at their ends. System of levers is composed of variable-slope slider-crank mechanism. Said levers 2, 5 with rolls 7, 8 at their ends of said variable-slope slider-crank mechanism run about axles E, D coupled with wheel axle 9. Rod of piston 6 can axially displace on wheel axle 9 to bring rolls 7, 8 in contact with wheel edges.

EFFECT: higher load carrying capacity.

Chassis // 2486094

FIELD: transport.

SUBSTANCE: invention relates to machine building. Chassis consists of two driven wheels 1, 2 arranged on every side of the vehicle. Wheels 1, 2 have flanges 3, 4 articulated with drive side roller 5. Air castor 7 aligned with said roller 5 is fitted on drive axle 6. Air castor 7 features free bilateral rotation and has no articulation with roller 5. Note that its diameter is commensurable with that of wheels 1, 2.

EFFECT: easier motion over flights of stairs.

SUBSTANCE: invention relates to caterpillar transport facilities and may be used in wheeled chairs, Planetokhods, and off-road vehicles. Caterpillar propulsor comprises frame 1, caterpillar tracks running over drive sprocket 5, idler 6, and road wheels 7. One of said sprockets is equipped with drive with brake 8. Sprockets are shaped to equilateral triangle 9 with rim 12 and fitted off-center to engage with inner-gearing wheels 12 fixed on the frame. Drive sprocket and idler are arranged plane-parallel relative to each other.

EFFECT: higher efficiency and controllability.

SUBSTANCE: invention relates to fitting different-width caterpillars on snowmobile. Spacers 158A are arranged between sides of tunnel 18A for caterpillar and compartment 20 for engine 24. Width of said spacers 158A is selected to suit required width W1 of the tunnel. Note here that identical configuration of engine compartment 20 at tunnel different width W1 may be ensured as follows. At least, one air intake control device 110, for example, carb, is arranged behind engine 24 to communicate with engine air intake. Countershaft 100 is arranged behind the engine, above air intake and ahead of device 110. Therefore, identical distance X between central line 61 and engine end is ensured in snowmobiles with different caterpillar width.

EFFECT: improved design configuration.

SUBSTANCE: track-type machine mover contains support frame, wide-section caterpillar band with tracks, steering device and track roller group comprising turning and non-turning sections. Tracks are made symmetrically tapering from central part to ends and are interconnected by continuous resilient member fixed in track central part with possibility to bend vertically and horizontally in any of its cross-sections. Track horns or pins are made in the central part of caterpillar band along its longitudinal axis. Steering device comprises caterpillar band stabiliser, guiding wheel, turning section of track roller groups and vertical hinge. Fixed support of vertical hinge is mounted on support frame and movable support is connected with turning section of track roller groups. Vertical axis of vertical hinge is separated from vertical plane passing through horizontal axis of turning section track roller group by distance of 0.3-0.8 of distance between horizontal axes of adjacent caterpillar band tracks.

EFFECT: widening of technical facilities arsenal.
