Abstract

An integral track type tank with light weight, low running resistance, oil consumption and wear, and high speed and load bearing power features that its wheels is moving on two closed endless ring tracks, and when it is running the sand or cobble can not come in its track.

Description

Caterpillar tank car

Existing crawler vehicle all is that some wheels travel on the broken rail that two row's links are got up.Its shortcoming is that construction weight is big, and walking resistance is big, and oil consumption is big, and wearing and tearing are big, and speed is low, and load-carrying capacity is low.

The present invention has designed a kind of whole rail type caterpillar car, and this car wheel moves on the circular orbit of two groups of closures, and wheel is accomplished when load-bearing on the rail under the wheel.And then make car in motion foreign matters such as sand, stone be difficult to enter contact surface between rail, the wheel.

The present invention is applicable to military tank, armored personnel carrier, self-propelled gun and amphibian etc.

Be applicable to that trac., bulldozer, excavating machine, loader, big part transport equipment and big part self-chambering, self-unloading operation on civilian.

Among Fig. 11 is whole rail, and 2 are whole rail level, and 3 is roller, and 4 is roller mount, and 5 is the power output chain gear, and whole rail 1 can be fixed with some springing and car body.Sprocket wheel 5 also can do become to resemble Fig. 4 smaller.When sprocket wheel 5 clockwise rotated, roller mount 4 bottom was motionless, but the roller 3 above it clockwise rotates under the drive of following rail level.Whole rail 1 is moving forward, and goes up roller 3 and roller mount 4 play forward above the rail level.The roller 3 in the place ahead and roller mount 4 be motion downwards together, for whole rail 1 is paved the way.

Fig. 2 is the scheme drawing of whole rail.6 is last rail level retaining platform, and it makes roller unlikely left and right sides play when upper and lower rail level rolls too big.Forward and backward rail level also is like this.The 7th, last rail level, roller 3 can roll thereon.The 8th, last rail level small opening, it makes drops on down rail level with silt particle that go up to go up rail level and carries on the back on 10 the inclined-plane and tumble in the both sides, track.9 are following rail level, and it can move on roller 3.

Fig. 3 is the scheme drawing of roller and roller mount.11 is roller mount, the 12nd, and it can play buffering and counterpressure pressure spring.This spring also can be uneasy as required.The 13rd, roller mount lower faceplate, lower faceplate are done the level height that camber can make roller 3, and no matter where lower faceplate 13 lands, and it all remains unchanged substantially.Airborne dust when it can reduce motion in addition.Two end faces of lower faceplate 13 will be shut, and become band joint half thick bamboo tube shape, like this on sand ground, marsh, building site during walking with regard to unlikely be absorbed in too dark.The left side of lower faceplate 13 is a protruding garden shape, and the right is a recessed garden shape, is linked at a time-out convex-concave garden in each roller mount like this and closes from beginning to end and can play the effect of not carrying silt particle secretly.

Bottom surface in roller mount 13 can be made the light face.A factor roller mount 13 links have just formed one group of shape that can increase friction force together.The bottom surface of certain single roller mount 13 also can be made sculptured or openwork carving formula decorative pattern, in order to further increase and ground-surface friction force.The bottom surface of roller mount 13, available metal is manufactured, also material such as available plastic, rubber.Also can be with it attached on the metal covering.

Two a plurality of independent hinge axis of adjacent rollers seat 13 usefulness connect together, and wherein have one or several to be had no relations by being blown up also, as long as there are two to connect together and just can advance in the same old way.

14 is the roller mount bearing, and 15 is roller bearing, and 16 is the chain shaft bearing, the sprocket engagement on the Shi Yuqi of meeting of it and sprocket wheel, and can on upper and lower rail level, roll when leaving.17 is roller shaft, and the bearing contingency that it is adorned above has one or several to be blown up or the motor function of locking roller may be influenced not at all.If 14 a pair of badly complete, 15,16 is also rotatable; If 15,16 have bad, a pair of 14 is also rotatable.Above-mentioned bearing can be used antifriction-bearing box, also available plain bearing.

Fig. 4 is the scheme drawing of amphibious vehicle.18 is amphibious vehicle, and 19 is the power output chain gear.20 is aiutage, and 21 is water.The power output chain gear 19 of the easiest water inlet all can be loaded on more than the water surface with aiutage 20 as can be seen from Figure.Below just can make a seamless hull bottom vehicle body.Go up rail level on the water among the figure, following rail level rotates all rollers and all motions backward of roller mount of rail level at present when sprocket wheel 19 up times under water, and the result is under the antagonistic force of water, and amphibious vehicle travels forward, and can be by the different rotating speeds change of direction of vehicle two row's sprocket wheels.Certainly also can adorn propeller and rudder in addition, but this structure is just complicated.

Crawler belt shape of the present invention can be done as required than major adjustment, and the alerting ability when increase turning as need just can shorten below the crawler belt and ground-surface length of contact.Increase load carrying ability if desired and then can strengthen length of contact, even increase the quantity of crawler belt combination.

But Fig. 5 is the whole rail of the combination of change in elevation.It has formed a parallelogram by last rail bar 23 and the upright rail 25 of a following rail bar 26 and a left side and the right rail 27 that stands under the binding of four axles 24, each rail termination all is that the garden heart with axle 24 is the isometrical concentric garden of the garden heart.Steady in the same old way when turning round on the rail bar of roller 3 in variation like this.Last rail bar 23 is fixed onboard, and the upper end of hydraulic part 22 is also fixing onboard, and its lower end is fixed on down on the rail bar 26, and last rail bar 23 and car are all followed variation when the hydraulic part length variations.Even military vehicle also change in elevation at any time under steam like this.Amphibious vehicle among Fig. 4 also can assemble draft and conciliation headstock the elevation angle in water of this device in order to reconcile down rail bar.The water that this car is no matter how dark, no matter how shallow water can both be walked.

This device can be accomplished to load and unload voluntarily when transporting big part, can be built on stilts big part in advance, and the low appearance of car enters, and high appearance jack-up is removed frame, walking.Otherwise vehicle-mounted big high appearance stops, and adds frame under the big part, and the low appearance of car withdraws from.

Above-mentioned structure makes vehicle of the present invention can improve speed and load-carrying capacity greatly, reduces construction weight, reduces resistance, reduces wear, and reduces energy consumption, but and change in elevation, load and unload big part voluntarily.
