Abstract

A creeper tread mainly solves the technical problems that the existing creeper tread has smaller stressed area, comparatively poorer trafficability and the like. The key points of the technical scheme of the creeper tread are that the creeper tread comprises a tread body (2), induction lugs (1), articulated joints (5) and articulated grooves (6), wherein a tread body outside extension tread (7) extending outwards is arranged at the articulated joint which is positioned at the outer side of the tread body (2); or a tread body inside extension tread (8) extending inwards is arranged at the articulated joint which is positioned at the inner side of the tread body (2); or the tread body outside extension tread (7) and the tread body inside extension tread (8) are adopted simultaneously. Since the extension tread or extension treads is or are arranged at one side or two sides of the tread body, under the condition that the existing vehicle chassis is not changed, the stressed area of a creeper band is increased, so that a vehicle can pass through topographies such as wetlands better; and the creeper tread can be applied to various armored vehicles, creeper fire-fighting vehicles and the like.

Description

Caterpillar block

Technical field

The utility model relates to a kind of caterpillar block that is used for armored vehicle.

Background technology

At present, the caterpillar block that is used for armored vehicle comprises that mainly 2,2 of plate bodys induce ear 1, a plurality of articulated joint 5 and a plurality of hinge recess 6, articulated joint 5 interlocks side by side in one plane for 6 one-tenth with hinge recess, and the two ends cross-distribution, so that identical 2 caterpillar blocks are connected; Existing plate body medial surface 3 and existing plate body lateral surface 4 that existing plate body 2 both sides are positioned at outside articulated joint place are intilted symmetrical structure, and promptly similar echelon form structure, plate body 2 both sides length are no more than the articulated joint of both sides, consult Fig. 1 to Fig. 3.Owing to be subjected to the restriction of vehicle chassis structure, all be to adopt this kind version.But still there are shortcomings such as area of thrust surface are less relatively in it, particularly when vehicle during by marshy area, is subjected to necessarily restricted.

Summary of the invention

The purpose of this utility model provide a kind of under the situation that does not change existing vehicle chassis, can increase the caterpillar block of area of thrust surface.

The technical scheme that its technical matters that solves the utility model adopts is: it comprises plate body 2, induces ear 1, articulated joint 5 and hinge recess 6, it is characterized in that: be positioned at the plate body outside extended plate 7 that plate body 2 outside articulated joints place are provided with outside stretching, extension.Plate body outside extended plate 7 is with respect to stretching 30-70mm outside the articulated joint lateral, the outside, preferred 60mm.The width of plate body outside extended plate 7 is equal to or less than the width between the plate body 2 two ends hinge recess 6 and becomes projection.

The utility model also can be positioned at the inboard extended plate 8 of plate body that plate body 2 hinged inside head places are provided with inside stretching, extension.The inboard extended plate 8 of plate body is with respect to the inboard 3-7mm that inwardly stretches of hinged inside head, preferred 6mm.The width of the inboard extended plate 8 of plate body is equal to or less than the width between the plate body 2 both sides hinge recess 6 and becomes projection.

The beneficial effects of the utility model are: by the one or both sides at plate body extended plate is set, do not changing under the situation that has vehicle chassis now, can increase the crawler belt area of thrust surface, thereby can make the vehicle can be better by landform such as marshy areas, it can be applicable to various armored vehicles, and the crawler belt fire-fighting vehicle etc.

Among the figure: 1-induces ear, the 2-plate body, and 3-has the plate body medial surface now, and 4-has the plate body lateral surface now, 5-articulated joint, 6-hinge recess, 7-plate body outside extended plate, the inboard extended plate of 8-plate body.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further details.

Embodiment 1, and the utility model comprises plate body 2, induces ear 1, articulated joint 5 and hinge recess 6, is being positioned at the plate body outside extended plate 7 that plate body 2 outside articulated joints place are provided with outside stretching, extension, plate body outside extended plate 7.Plate body outside extended plate 7 is with respect to stretching 30-70mm outside the articulated joint lateral, the outside, preferred 60mm.For ease of track pin is installed, the width of plate body outside extended plate 7 is equal to or less than the width between the plate body 2 two ends hinge recess 6 and becomes projection, and optimal case is that the width of plate body outside extended plate 7 equals the width between the plate body 2 two ends hinge recess 6.Consult Fig. 4 to Fig. 6.

Embodiment 2, and the utility model comprises plate body 2, induces ear 1, articulated joint 5 and hinge recess 6, is being positioned at the inboard extended plate 8 of plate body that plate body 2 hinged inside head places are provided with inside stretching, extension.Because the utility model is in the technological improvement that does not change under the vehicle chassis situation, the inboard extending space of plate body 2 is limited, and by calculating and design, the inboard extended plate 8 of plate body is with respect to the inboard 3-7mm that inwardly stretches of hinged inside head, preferred 6mm.For ease of track pin is installed, the width of the inboard extended plate 8 of plate body should be equal to or less than the width between the plate body 2 both sides hinge recess 6 and become projection, and optimal case is that the width of the inboard extended plate 8 of plate body equals the width between the plate body 2 both sides hinge recess 6.Consult Fig. 4 to Fig. 6.

Embodiment 3, and the utility model comprises plate body 2, induces ear 1, articulated joint 5 and hinge recess 6, is being positioned at the plate body outside extended plate 7 that plate body 2 outside articulated joints place are provided with outside stretching, extension, plate body outside extended plate 7.Plate body outside extended plate 7 is with respect to stretching 30-70mm outside the articulated joint lateral, the outside, preferred 60mm.The width of plate body outside extended plate 7 is equal to or less than the width between the plate body 2 two ends hinge recess 6 and becomes projection.Simultaneously, be positioned at the inboard extended plate 8 of plate body that plate body 2 hinged inside head places are provided with inside stretching, extension.The inboard extended plate 8 of plate body is with respect to the inboard 3-7mm that inwardly stretches of hinged inside head, preferred 6mm.The width of the inboard extended plate 8 of plate body is equal to or less than the width between the plate body 2 both sides hinge recess 6 and becomes projection.Consult Fig. 4 to Fig. 6, all the other are with

embodiment

1 or 2.
