Description

A kind of resilient track

Technical field

It the utility model is related to a kind of pedrail mechanism, more particularly to a kind of resilient track.

Background technology

Crawler belt refers to the endless strand that caterpillar travels over, and is by active wheel drive, around driving wheel, negative The flexible chain link of roller, inducer and carrier wheel.Crawler belt is made up of creeper tread and track pin etc..Track pin connects each creeper tread Get up to form track link.There is hole at the both ends of creeper tread, are engaged with driving wheel, and there is induction tooth at middle part, for advising positive crawler belt, and prevent Rotation stop to or roll travel when crawler belt come off, have in the one side contacted with ground and strengthen anti-skidding muscle, to improve the firm of creeper tread Property and crawler belt and the adhesive force on ground.

But the steering procedure of creeper truck simultaneously has some setbacks, turn to when, track pin can by very strong twisting resistance and frictional force, Long-term so track pin is easy to damage, and especially track pin centre position is easiest to damage, and more likely causes crawler belt or car Overall damage, result in greater loss.Therefore a kind of new technological means is needed to solve this problem.

Utility model content

The purpose of this utility model is to provide a kind of resilient track, to solve the crawler belt being previously mentioned in above-mentioned background technology The problem of pin is easily damaged.

To achieve the above object, the utility model provides following technical scheme：A kind of resilient track, including creeper tread and bullet Property track pin, the front and rear sides of the creeper tread are fixed with pin-and-hole, worn between the adjacent track plate by resilient track pin Pin-and-hole rotation connection is crossed, the upper surface of the creeper tread is provided with some caterpillar teeths side by side along its length.

As a kind of optimal technical scheme of the present utility model, the resilient track pin includes pin, positioning disk and elastic force Part, the positioning disk share three groups, every group two, are respectively arranged at the both ends and centre position of pin, positioning disk described in every group Between be uniformly provided with some spring elements.

As a kind of optimal technical scheme of the present utility model, the spring element rounded position distribution on positioning disk.

As a kind of optimal technical scheme of the present utility model, the creeper tread is provided with some material spilling holes.

As a kind of optimal technical scheme of the present utility model, the material spilling hole is square or circular, every piece of crawler belt At least provided with two groups of material spilling holes on plate.

As a kind of optimal technical scheme of the present utility model, some inclination caterpillar teeths can be also provided with the creeper tread.

The beneficial effects of the utility model：The utility model has buffered track pin institute in steering procedure by resilient track pin A part of example being subject to, especially in the centre of easy damaged and end positions, the service life of track pin is substantially prolongs, ensure to carry out The general safety of band and vehicle, prevents from causing a hidden trouble, the utility model is simple in construction, easy to use, is preventing crawler belt damage side Face has preferable effect practical, is easy to promote the use of.

Brief description of the drawings

Accompanying drawing is used for providing further understanding to of the present utility model, and a part for constitution instruction, with this practicality New embodiment is used to explain the utility model together, does not form to limitation of the present utility model.In the accompanying drawings：

Fig. 1 is the utility model overall structure diagram；

Fig. 2 is track pin structural representation；

Fig. 3 is another example structure schematic diagram of the utility model；

1- creeper treads in figure, 2- pin-and-holes, 3- track pins, 4- material spilling holes, 5- caterpillar teeths, 6- tilt caterpillar teeth, 31- pins, 32- positioning disks, 33- spring elements.

Embodiment

Lower combination accompanying drawing illustrates to preferred embodiment of the present utility model, it will be appreciated that described herein preferred Embodiment is merely to illustrate and explained the utility model, is not used to limit the utility model.

Embodiment 1

Fig. 1 and Fig. 2 are referred to, the utility model provides following examples：A kind of resilient track, including creeper tread 1 and bullet Property track pin 3, the front and rear sides of the creeper tread 1 are fixed with pin-and-hole 2, pass through resilient track between the adjacent track plate 1 Pin 3 is rotatablely connected through pin-and-hole 2, and the upper surface of the creeper tread 1 is provided with some caterpillar teeths 5 side by side along its length.

Resilient track pin 3 includes pin 31, positioning disk 32 and spring element 33, and the positioning disk 32 shares three groups, every group two It is individual, the both ends and centre position of pin 31 are respectively arranged at, some spring elements are uniformly provided between positioning disk 32 described in every group 33；Power of the cooperation available buffer part for elastic component 33 and positioning disk 32 in rotation process suffered by pin 31, especially in Between and end positions, so spring element is distributed in into the two positions, the probability of track pin damage can be greatly reduced, extending it makes With the life-span, ensure vehicle safety, while the rounded position distribution on positioning disk 32 of spring element 33 so that arround each pin 31 Each orientation can more can guarantee that the use of track pin by the influential effect of spring element 33.

And creeper tread 1 is provided with some material spilling holes 4, material spilling hole 4 is square or circular, and every piece of creeper tread 1 is up to Two groups of material spilling holes 4 are provided with less, can prevent that debris is deposited on crawler belt when driving, are caused later stage cleaning difficult, are caused not Just.

The utility model has buffered a part of example in steering procedure suffered by track pin by resilient track pin, especially exists The centre of easy damaged and end positions, the service life of track pin is substantially prolongs, ensure the general safety of crawler belt and vehicle, prevented Only cause a hidden trouble, the utility model is simple in construction, easy to use, has preferable effect practicality in terms of crawler belt damage is prevented By force, it is easy to promote the use of.

Embodiment 2

Referring to Fig. 3, the present embodiment in place of the difference of embodiment 1 with being：Also some tilt can be provided with creeper tread 1 to carry out Band tooth 6, improve crawler belt grabs ground effect, it is ensured that its driving safety.

Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic Progress equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc., It should be included within the scope of protection of the utility model.
