Description

A kind of engineering spiral wheel construction

Technical field:

The utility model belongs to traffic and transport field, and in particular to a kind of engineering helical wheel, the helical wheel are suitable for a variety of The running gear of engineering machinery vehicle is suitable for a variety of bad roads such as ice and snow, marsh.

Background technique:

Currently, engineering truck mainly has wheeled and two kinds of vehicles of crawler type.In face of different landform, need using different Vehicle carries out operation.Wheeled vehicle is flat suitable for topography, the harder prevailing roadway of earth's surface.Caterpillar is suitable for earth's surface pine Soft road surface.However, when in face of the rough topographys condition such as ice and snow, marsh, miriness, the running gear of existing engineering machinery vehicle without Method meets work requirements.

Spiral wheel construction proposes design concept in American inventor Jacob Morath in 1868 earliest.American in 1907 James and Ira Peavey produces first screw propulsion vehicle, is using spiral cutting principle, is suitable in snowfield, muddy ground, natural pond The special vehicle of the rough topographys such as pool walking.By helical wheel in conjunction with engineering machinery vehicle, can greatly improve vehicle ice and snow, The traffic capacity under the MODEL OVER COMPLEX TOPOGRAPHYs such as sand ground, marsh.

Utility model content:

In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of strong adaptabilities, the helical wheel knot of cross-country traveling ability Structure.

Spiral wheel construction provided by the utility model, including central axis, two fluted discs and four helical blades, the spiral Blade at least forms a complete circle on center shaft.

The spiral wheel construction, central axis select straight cylinder, and root diameter is between 20-26cm, center at fluted disc Shaft diameter is 4-6cm smaller than root diameter at helical blade, and tooth two sides reserve the space 0.5-1cm.Preceding fluted disc is located at this spiral shell At the 1/3 of spinning roller length, rear tooth disk is located at the end of this helical wheel.Helical wheel is divided into different in size, diameter by preceding fluted disc Identical two parts, and anterior length is the 1/2 of rear portion.

The spiral wheel construction, each two panels helical blade in front and rear part, helical blade rotation arrangement track beginning away from At central axis front end face 1-2cm, center shaft end is terminated at.Helical blade track screw pitch is between 10-15cm, helical-blade Piece inner edge to outer rim upper convex surface vertical range between 3-5cm.

The helical blade inner edge of the spiral wheel construction connects with central axis, and helical blade forms center relative to central axis Symmetrically, and on center shaft it alternately spirals.The helical blade at spiral wheel construction rear portion is rotated along anterior leaflet track Arrangement, fluted disc outer rim on-bladed surround.

The helical blade thickness is gradually reduced from inner edge to outer rim, and helical blade outer rim retains 0.6-0.8cm thickness Rather than bladed, and helical blade outer rim is placed equidistant with raised lines along track.

Various shapes, length and helical blade outer rim consistency of thickness can be used in the outer rim protrusion lines of the helical blade, Between 0.3-0.5, width voluntarily adjusts thickness according to lines.

Utility model has the advantages that

1. can be widely applied to various engineering vehicle, such as haulage vehicle, logging vehicle；2. can meet ice and snow, miriness, Traveling demand under the complicated severe pavement conditions such as marsh, enhances passability, improves safety；3. can reduce the cutting to ground It destroys.

Detailed description of the invention: 3 helical blade of fluted disc, 4 blade protrusion lines, 5 rear tooth disk before 1 central axis 2

Specific embodiment:

Below by attached drawing, the technical solution expansion of the utility model patent is further explained in detail.

As shown in Figure 1, spiral wheel construction provided by the utility model, including central axis 1, preceding fluted disc 2, helical blade 3, leaf Piece protrusion lines 4 and rear tooth disk 5.

As shown in Figures 1 to 5, the spiral wheel construction, central axis 1 select straight cylinder, forward and backward fluted disc geometrical characteristic one It causes, preceding fluted disc 2 is located at the 1/3 of this helical wheel length, and rear tooth disk 5 is located at the end of this helical wheel.Preceding fluted disc divides helical wheel To be divided into different in size, identical two parts of diameter, and anterior length is the 1/2 of rear portion.

As shown in Fig. 2, Fig. 6, the spiral wheel construction, each two panels helical blade in front and rear part, helical blade rotary rowed Cloth track beginning away from central axis front end face 1-2cm at, terminate at center shaft end.Helical blade track screw pitch is in 10- Between 15cm, the vertical range of helical blade inner edge to outer rim upper convex surface is between 3-5cm.

As shown in Figure 5, Figure 6, the helical blade inner edge of the spiral wheel construction connects with central axis, helical blade relative to Central axis forms central symmetry, and alternately spirals on center shaft.The helical blade at spiral wheel construction rear portion is along front leaf Piece track carries out rotation arrangement, and preceding 2 outer rim on-bladed of fluted disc surrounds.

As shown in fig. 6, the helical blade thickness of the spiral wheel construction is gradually reduced from inner edge to outer rim, outside helical blade Edge retains 0.6-0.8cm thickness rather than bladed, and helical blade outer rim is placed equidistant with raised lines along track.

As shown in fig. 7, at the helical blade of the spiral wheel construction root diameter between 20-26cm, at fluted disc in Mandrel diameters are 4-6cm smaller than root diameter at helical blade, and fluted disc two sides reserve the space 0.5-1cm.

As shown in figure 8, various shapes, length and helical blade outer rim can be used in the outer rim protrusion lines of the helical blade Consistency of thickness, between 0.3-0.5, width voluntarily adjusts thickness according to lines.

The above is preferred embodiments of the present invention, and the protection scope of the utility model is not limited to the reality Mode is applied, therefore the restriction of the equivalence changes according to made by structure described in the utility model, feature, principle, size should all be covered by this Within the protection scope of utility model technical solution.
