Tubular chain link body

Claim 2

A track link body for track-laying vehicles, which includes: two glass-fiber-reinforced tubular members of synthetic resin arranged in spaced substantially parallel arrangement with regard to each other, and glass-fiber-reinforced sideplate means respectively arranged on opposite sides of said tubular members and interconnecting the same.

Claim 3

A track link according to claim 1, in which said sideplate means include glass fiber fabric material.

Claim 4

A track link according to claim 1, in which said sideplate means include glass fiber strands permeated with synthetic resin and looped around said tubular members in a continuous manner and also in a manner so as to cross each other between said tubular members.

Claim 5

A track link according to claim 1, which includes metallic insert plate means partially extending between said tubular members and comprising portions cupping said tubular members.

Claim 6

A track link according to claim 4, in which said insert plate means is of steel.

Claim 7

A track link according to claim 5, in which Said tubular members are cemented to said cupping portions.

Claim 8

A track line according to claim 4, in which said insert plate means has those areas thereof which are adjacent to said cupping portions provided with rail means defining groove means for receiving ground-contacting members.

Claim 9

A track link according to claim 4, which includes rubber cushion means connected to said metallic plate means and cupping those areas of said tubular members which are opposite to those cupped by said metallic insert plate means.

Claim 10

A track link according to claim 10, in which said cushion means is connected to said tubular members.

Claim 11

A track link according to claim 8, which includes supporting plate means having vulcanized thereto that portion of said cushion means which is adjacent said insert plate means, and connecting means connecting said supporting plate means to said insert plate means.

Claim 12

In a method of producing a track link body for track-laying vehicles which has two glass-fiber-reinforced tubular members of synthetic resin in parallel spaced relationship to each other, the steps of: preparing each of said glass-fiber-reinforced tubular members by applying glass fiber material to a cylindrical core member having an outer diameter corresponding to the inner diameter of the tubular member to be prepared, and permeating the said applied glass fiber material with synthetic hardenable resin while winding said glass fiber material upon said core member until the thus obtained structure has reached a diameter corresponding to the desired strength of said tubular member and securing the ends of the tubular members in spaced parallel relationship to each other by a pair of connecting plates to thereby form a track link body.

Claim 13

In a method of producing a track link body for track-laying vehicles which has two glass-fiber-reinforced tubular members of synthetic resin in parallel spaced relationship to each other, the steps of: preparing each of said glass-fiber-reinforced tubular members by applying glass fiber material to a cylindrical core member having an outer diameter corresponding to the inner diameter of the tubular member to be prepared, and permeating the said applied glass fiber material with synthetic hardenable resin while winding said glass fiber material upon said core member until the thus obtained structure has reached a diameter corresponding to the desired strength of said tubular member and securing the ends of the tubular members in spaced parallel relationship to each other by a pair of connecting plates to thereby form a track link body.

Claim 14

A method according to claim 1, in which said glass fiber material is applied in the form of glass fiber woven pieces.

Claim 15

A method according to claim 1, in which said glass fiber material is applied in the form of glass fiber strands and looped around said core members in a continuous straight and in an intercrossing manner.
