Description

Track unit

The utility model relates to a kind of running gear, particularly be a kind of track unit that is used on the machines such as tiller, trac..

The supporting track unit of existing and machines such as tiller, trac. is prone to the phenomenon that caterpillar block and stay bearing plate misplace mutually when turning, when ploughing, be prone to simultaneously card stone, card careless, skid etc., as when walking, meeting card stone or grass, easily crawler belt being stretched tight very tight, cause driving engine overload or automatically extinguishing, when serious, tooth in the change speed gear box is broken, and labour intensity is big, and complete machine stability is poor.

In view of above reason, the purpose of this utility model is in order to provide a kind of labour intensity little, to walk easily, can improve the track unit in complete machine stability and service life.

The purpose of this utility model is achieved in that the utility model comprises teeth groove on the corresponding sides bracing frame, the periphery that is loaded on the bracing frame two ends is polygonal corner angle drive wheel, the corner angle flower wheel, crawler belt, the corner angle drive wheel, the equidistant roller that is equipped with on the corner angle flower wheel periphery, formed between cog between roller and roller, on the inner face of crawler belt equidistant have dozens of can with cooperate and the driving cog that can move along the teeth groove in the bracing frame of between cog between roller and roller, pin nail is arranged (referring to Fig. 1～Fig. 9) on the outside of crawler belt, roller on corner angle drive wheel and the flower wheel reduces friction except that with going back axial rotation drive wheel or the flower wheel revolution, laborsaving, increase the life-span.

Tell mud hole (referring to Fig. 1, Fig. 2) on the above-mentioned corner angle drive wheel.

There is the adjusting that contains with bracing frame bonded assembly and scalable distance therebetween very heavy on the above-mentioned bracing frame, regulating has regulating tank on very heavy, driven shaft is through in regulating tank and the flower wheel axis hole and flower wheel is connected (referring to Fig. 1) on the bracing frame, the degree of tightness of scalable crawler belt.

Above-mentioned crawler belt by the tens of blocks of tooth piece plates that contain driving cog combine (referring to Fig. 1, Fig. 6～Fig. 9), mounting or dismounting are changed convenient, but cost-cutting.

Pin nail on the above-mentioned crawler belt is splayed (referring to Fig. 9), non-slip, good stability.

Be positioned at the teeth groove place on the above-mentioned bracing frame roller groove is arranged, the roller that several or dozens of cooperate with crawler belt is arranged (referring to Fig. 1, Figure 10～Figure 12) in the roller groove, the cliding friction of crawler belt and bracing frame is become friction of rolling, reduce wear, prolonged the service life of stay bearing plate and crawler belt, it is lighter to walk, and it is more flexible to turn.

Above-mentioned teeth groove and roller groove are an integral body, are connected on the bracing frame (referring to Figure 10～Figure 12), it is convenient that processing uses the dress folding to change by connector, according to different crawler belts and chain,, take off roller groove, teeth groove as long as take off connector, chain or other crawler belt just can be installed, and a bracing frame is used more.

Referring to Fig. 1, during the utility model work, power passes on the crawler belt through roller on the corner angle drive wheel and the driving cog on the crawler belt, and again through the driving cog on the crawler belt with the roller on the flower wheel that cooperates with it and drive flower wheel and rotate, running gear is (or back) walking forward.Meanwhile, deposit in the groove of driving cog with bracing frame earth, weeds etc. by flower wheel be transmitted back to drive wheel again telling from drive wheel spue the mud hole, phenomenons such as thereby the card stone, the card that have been occurred when having overcome existing track unit arable land are careless, skid, be not afraid of any resistance obstacle, walking freely in dumped riprap at random, stone, random grass can't block it, thereby walking reaches the optimum efficiency of the power of output to the driving force of plough point flexibly.During the crawler belt operation, driving cog is arranged in the between cog of corner angle drive wheel, corner angle flower wheel and the teeth groove of bracing frame all the time, the phenomenon that misplaces between crawler belt and bracing frame can not occur, alleviate labour intensity greatly, strengthened the stability of complete machine, can reach one-handed performance.The roller groove that contains roller by the connected teeth groove of connector is set on bracing frame, can be different as required, as long as take off connector, chain or other crawler belt just can be installed.

The utility model walking is light, turning is flexible, and easy to maintenance, labour intensity is little, can improve the convenient bracing frame of complete machine stability and service life mounting or dismounting greatly and use more.Applied widely, can with tiller, tractor, also can be used for doing on other type running gear and use.
