Abstract
The utility model discloses a force assistance turning band track, belongs to the technical field of mechanical walk, and mainly aims at solving the problem that an existing chain track vehicle is high in production cost or can bring great damage to road surfaces at turning time. The force assistance turning band track is a wheel-type chain band track composed of chains and chain bending plate sections fixed on two sides of each chain. Bending plate surface baffles are respectively connected with two ends of each section of two symmetrical chain bending plate sections on the two sides of each chain. The bending plate surface baffles refer to two bending plate surface baffles in the same shape. A cylindrical baffle extending out of the outer planes of the bending plate surface baffles is arranged between the two bending plate surface baffles in the same shape, or the bending plate surface baffles refer to two bending plate surface baffles with different heights. The force assistance turning band track has the advantages of reducing cost and damage caused by a chain track vehicle to road surfaces in urban areas, and achieving turning of a band track vehicle though difference of heights, and is mainly used for a wheel chain track vehicle to turn on relatively smooth cement road surfaces.
Description
Technical field
The utility model belongs to the machine-walking technical field, is specifically related to a kind of power-assisted turning crawler belt that wheeled chain crawler vehicle is turned on comparatively smooth cement pavement that is used for.
Background technology
Because the working environment of various special vehiclees is different; The special vehicle (comprising excavating machine, combination machine, tank etc.) that has some under special environment, to work has been equipped with wheeled chain crawler belt, and the turning problem of these wheeled chain crawler vehicles is just arisen at the historic moment.
At present, the method for the wheeled chain crawler vehicle of the solution that occurs on the market has two kinds: a kind of is on power take-off shaft, to increase to turn to brake system, at Ackermann steer angle, is realized turning by the crawler belt that turns to brake system to block turn direction; Another kind is on wheeled chain crawler belt, to add tiny relatively crowning, makes crawler belt and ground realize that point contacts.Not enough below existing in the said method: the former has strengthened productive costs, and the destructiveness of latter's road pavement is bigger.
Summary of the invention
The purpose of the utility model be to the problems referred to above provide a kind of can cost-cutting, can reduce wheeled chain crawler vehicle again the city ground-surface is destroyed, realize the power-assisted turning crawler belt that crawler vehicle is turned through high low head.
The technical solution of the utility model is: a kind of power-assisted turning crawler belt; By the wheeled chain crawler belt that chain and the chain bent plate joint that is fixed on the chain both sides are formed, its characteristics are: the two ends of the two chain bent plates joint of every joint symmetry are connected with bent plate surface baffle plate respectively in the chain both sides; This bent plate surface baffle plate is two identical bent plate surface baffle plates of shape; And between two identical bent plate surface baffle plates of these two shapes, add and stretch out the outerplanar cylindrical baffle of this bent plate surface baffle plate, perhaps these two bent plate surface baffle plates are two highly different bent plate surface baffle plates.
The horizontal drop of the bent plate surface baffle plate that two described in the technical solution of the utility model are highly different is 2mm-10mm.
The horizontal drop of cylindrical baffle described in the technical solution of the utility model and bent plate surface baffle plate is 2mm-10mm, and the angle between cylindrical baffle and the bent plate surface baffle plate is 0-45 °.
Cylindrical baffle of interpolation on every joint crawler belt of the wheeled chain crawler belt described in the technical solution of the utility model, on the one joint crawler belt of perhaps every interval, on the two joint crawler belts of perhaps every interval.
The utility model is owing to adopt the power-assisted turning crawler belt that is made up of chain, chain bent plate, bent plate surface baffle plate and cylindrical baffle; Wherein, Cylindrical baffle is added between chain bent plate and the bent plate surface baffle plate; Stretch out the outerplanar of this bent plate surface baffle plate, perhaps adopt the power-assisted turning crawler belt that constitutes by chain, chain bent plate, highly different bent plate surface baffle plates, thereby the perhaps high low relatively bent plate surface baffle plate of bent plate surface baffle plate of cylindrical baffle is formed with the fulcrum of higher drop; When machine operation; The snap-in force of support wheel and high drop fulcrum makes the chain stop motion, thereby makes machine turn to friction force greater than the craspedodrome friction force, finally realizes the turning effect of wheeled chain crawler vehicle.The utlity model has cost-cutting, reduce wheeled chain crawler vehicle the city ground-surface is destroyed, realize the characteristics that crawler vehicle is turned through high low head.The utility model is mainly used in wheeled chain crawler vehicle and on comparatively smooth cement pavement, turns.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the local enlarged diagram of Fig. 1.
The birds-eye view of Fig. 3 Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
Like Fig. 1, Fig. 2, shown in Figure 3.The wheeled chain crawler belt of the utility model power-assisted turning crawler belt for constituting by chain, chain bent plate 2, bent plate surface baffle plate 4 and cylindrical baffle 3.Wherein, the chain bent plate 2 of every joint crawler belt is two parallel pitch chain bar bent plates, and two bent plates surface baffle plate 4 is fixed on this two pitch chains bar bent plate, 2 two ends, is prior art.Cylindrical baffle 3 is fixed on the two pitch chain bar bent plates 2 between the baffle plate 4 of two bent plates surface.The horizontal drop of cylindrical baffle and bent plate surface baffle plate is 2mm-10mm, and the angle between cylindrical baffle 3 and the bent plate surface baffle plate 2 is 0-45 °.1 cylindrical baffle 3 of interpolation on every joint crawler belt of wheeled chain crawler belt, on the one joint crawler belt of perhaps every interval, on the two joint crawler belts of perhaps every interval.
Crawler belt is when power-assisted is turned in the traveling process on comparatively smooth cement pavement, through midship mounting wheel 1 be installed in cylindrical baffles 3 in the middle of the crawler belt bent plate surface baffle plate 2 and realize that power-assisteds turn.During turning, the turn direction power wheel runs out of steam the crawler belt of turn direction is run out of steam, but since the friction force of turn direction greater than the resistance of craspedodrome direction, so still can not realize turning.The snap-in force that is installed in cylindrical baffle 3 and middle bearing wheel 1 in the middle of the crawler belt bent plate surface baffle plate 2 this moment makes the crawler belt stop motion, and then the friction force that makes turn direction is realized turning greater than the craspedodrome resistance.Thisly on the whole piece crawler belt, be installed in the cylindrical baffle 3 in the middle of the crawler belt bent plate surface baffle plate 2 according to different proportion; Make crawler belt not stop to reduce the friction force of turn direction, finally be implemented in power chain turning brake system and the crawler vehicle turning effect under the situation of attachment point contact track not are not installed.
The turn radius of this power-assisted turning crawler belt on the soil is 1/3rd of whole piece track length, and the turn radius on cement pavement is 2/3rds of a whole piece track length.
As adopting two highly different bent plate surface baffle plates, the horizontal drop of these two bent plate surface baffle plates is 2mm-10mm.In like manner, the high bent plate surface baffle plate and the snap-in force of middle bearing wheel make the crawler belt stop motion, and then the friction force that makes turn direction is realized turning greater than the craspedodrome resistance.
