The specific embodiment

Embodiment one

As Fig. 1～shown in Figure 6, a kind of auxiliary device based on wheel car is installed in existing four-wheel and drives entirely on the troop transporter, installs engaging and disengaging gear 7 on the propons of this kind troop transporter and the rear axle beam respectively additional.Have through hole on the wheel hub 1 of wheel car, these are existing structure.

The crawler belt auxiliary wheel partly comprises forged steel pieces auxiliary wheel 2, during making, guarantees that the auxiliary wheel diameter equates with the wheel external diameter.Process bolt hole on auxiliary wheel, bolt hole is corresponding with the through hole on the wheel hub, and auxiliary wheel is fixed on the wheel nave by bolt 3, forms double structure of taking turns.Scribble the thick rubber of one deck in the auxiliary wheel circumferential exterior surface, be used to increase elasticity.

One annular groove 21 is arranged on auxiliary wheel, and annular groove 21 bottoms are circular-arc, and annular groove is in the side near wheel hub.Annular groove 21 two sides circumferentially evenly have fixed orifice 22, and interspersed shank 23 in the fixed orifice can be at a series of teeth groove shape of the circumferential formation of annular groove.

Shank is a stepped shaft, is nested with axle sleeve at shank middle part, is provided with oil circuit in shank, and oil circuit is communicated to the surface at shank middle part, the purpose of the lubricating oil of can realizing annotating, and axle sleeve directly contacts with screw die.

Shank is located in the fixed orifice, passes through dismantled and assembled installation one washer 24 of screw in the outside of cooresponding fixed orifice, this catch 24 can be fixed on shank 23 in the fixed orifice of auxiliary wheel, prevents coming off of shank.

Shown in the A among Fig. 5, shoe is a sheet, dual-side has front contact and back contact respectively in the front and back of shoe, has the first penetrating pin-and-hole 31 of a left and right directions on the front contact, has the second penetrating pin-and-hole 32 of an above-below direction on the back contact, have the crosswise of being and mutual vertically arranged the 3rd pin-and-hole and the 4th pin-and-hole on one square 33, first pin-and-hole and the 3rd pin-and-hole flexibly connect by round pin, second pin-and-hole and the 4th pin-and-hole flexibly connect by round pin, constitute joint type and flexibly connect, making can be in fore-and-aft direction and left and right directions adjusted angle between two adjacent caterpillar blocks.Dental lamina 34 perpendicular to the shoe surface is set on the shoe, dental lamina can with the shank interlock mutually in the auxiliary wheel groove.Shoe connects and composes endless track successively, and crawler belt is installed on the wheel.

On Width, crawler belt 4 is just in time taken and is placed on wheel tyre and auxiliary wheel 2 outside faces, and on the length direction, crawler belt 4 just in time is crossed on the front and back wheel.Drive entirely because this troop transporter is a four-wheel, vehicle bridge is reequiped, set up engaging and disengaging gear.When turning to, the wheel of a side all locks, and the wheel revolutions of opposite side drives, and can realize the purpose of turning having similar steering capability with common crawler vehicle.

This embodiment possesses two kinds of functions: the one, and the crawler vehicle function is installed in wheel hub 1 outside with auxiliary wheel 2, installs in the groove that again crawler belt is hung over auxiliary wheel behind the shank to get final product; The 2nd,, if the shank in crawler belt and the auxiliary wheel annular groove is pulled down, in the annular groove of the front-wheel of homonymy and trailing wheel, twine a circle rope then, and the two ends of rope are separately fixed on the ground fixture before and after the vehicle, wheel, wheel car is advanced along rope, form the structure of similar capstan winch.

In this enforcement, the design of crawler belt has multiple, and shown in B among Fig. 5, front contact is a spheroid 35, has the through hole perpendicular to the crawler belt upper and lower surface on spheroid, through hole internal fixation one dental lamina 34; Have a segment 36 that matches with spheroid on the front contact on the back contact, spheroid and segment constitute the joint type movable joint.

Embodiment two

As Fig. 7, Fig. 8, shown in Figure 9, be that with embodiment one difference be installed in existing six and take turns on the kangroo, four-wheel drives entirely behind this car, two front-wheels are responsible for turning to.

Crawler belt 4 covers two rows are in the back taken turns, identical with the mounting means of embodiment one, difference is, one adjusted device is installed on front-wheel, this adjusted device comprises rebound 51, crotch 52, rope-winding wheel 53, motor 54, rebound 51 is a plectane, and rebound is by being bolted on the wheel nave.Crotch 52 is " Y " shape frame, and an end of " Y " shape crotch is hinged on the rebound 51 by bearing is rotating for the circle main body; The movable rope-winding wheel 53 of installing in other end prong place, rope-winding wheel is installed in the rotating shaft by key, the rotating shaft two ends by bearing installation on crotch 52, and an end of rotating shaft links to each other with drive motor by coupler, the diameter of rope-winding wheel 53 increases to both sides gradually from middle, can be on rope-winding wheel lay winding wire ropes.For prevent that adjusted device from rotating under the effect of slack-free steel rope, fixed limit post 55 on " Y " of rope-winding wheel both sides shape crotch 52, so-called limited post is a cylinder, the cylinder end face is welded on " Y " shape crotch, is nested with sleeve on the cylinder and is used to reduce friction force between steel rope and the limited post.

The utility model also has another ability except that the function that possesses embodiment one: an end of a rope is fixed on the fixture of vehicle front, the other end is wrapped on the rope-winding wheel of adjusted device, power to drive motor by automobile-used storage battery, drive motor can drive the rope-winding wheel rotation, rope is packed up, and then realized purpose that vehicle is extracted.

As shown in Figure 9, as another kind of distortion of the present utility model, if remove drive motor, rope ends can be fixed on simultaneously on the ground fixture of vehicle front and back, and rope is walked around the annular groove of next two row's auxiliary wheels and the rope-winding wheel of front-wheel successively, vehicle is advanced, and because the universal adjustment effect of crotch along rope, can effectively avoid the interference that bumps of rope and front-wheel.

Embodiment three

As Figure 10, Figure 11, shown in Figure 12, be that with embodiment two differences have three row's wheels, and have only front-wheel to have the function of turning to, back two row's wheels do not possess the function of turning to.

Crawler belt 4 is covered whole wheels, because front-wheel steering will cause the bending on the crawler belt generation left and right directions, so increased by a cover ways, this ways is the track adjusting wheel 61 with guide groove 62, this track adjusting wheel is fixed on " Y " shape crotch 52 by support 63.Support 63 is that an end is welded on " Y " shape crotch, and a circular hole is arranged on the other end, and track adjusting wheel 61 is installed in the circular hole, and track adjusting wheel can freely be rotated.The upper surface of track adjusting wheel is provided with guide groove, and guide groove is the little bell mouth shape of the big end opening of an end opening, makes the dental lamina of the crawler belt guide groove of can freely coming in and going out, and when front-wheel steering, has certain adaptive capacity.Support and track adjusting wheel are two respectively, are symmetrical arranged up and down, support the both sides up and down of crawler belt respectively, provide support a little for it turns to, and prevent that crawler belt from coming off.Installation has certain elastomeric tightening device 8 on car body simultaneously, can compensate crawler belt when Vehicular turn.This embodiment has further widened Applicable scope of the present utility model and occupation mode.

Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
