The utility model discloses a track structure is the triangle -shaped structure, and this structure has improved whole car terrain clearance effectively, guarantees the trafficability characteristic of whole car, the take -up pulley subassembly sets up two, has guaranteed the tensioning nature of whole track, the guide rail is set up to track top, prevents that the track is at the in -process of walking because of track tensioning off tracking not, the effectual normal operating of guaranteeing the track, the setting of floating roller meets the too big impact that ditch, bank or uneven road caused when having alleviateed the walking effectively.
Description
Technical field
This utility model relates to vehicle fitting technical field, more particularly to a kind of novel crawler-type Running System device.
Background technology
Crawler-type traveling system is only second to the Running System that rubber-tyred is widely used in engineering machinery. Crawler type walking mechanism has the advantages such as pull strength is big, grounding pressure power is little, climbing capacity is strong, and it is widely used in various engineering machinery, defines various tracked construction equipment. Common tracked construction equipment has: tractor, bull-dozer, excavator etc. At present, crawler travel system generally only sets a strainer, and only prop up by middle thrust wheel when clearing the jumps and be redirected, cause that headstock or tailstock moment when walking nose occurs or sticks up tail, derailed crawler belt fault easily occurs, brings very big impact to vehicle or operator, not only affect outside machinery operation efficiency, also minimizing crawler belt service life, increase device maintenance cost.
Utility model content
This utility model provides a kind of simple in construction, across obstacle ability strong, it is not easy to derailed crawler belt fault occur, track tension is high, long service life, a kind of novel crawler-type Running System device that maintenance cost is low.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of novel crawler-type Running System device, including fixed mount, driving wheel, crawler belt, thrust wheel and tensioning wheel assembly; Wherein: tensioning wheel assembly and thrust wheel all have two groups, front and back, and are all connected with fixed mount; Crawler belt forms triangular structure around driving wheel, front tensioning wheel assembly, rear tensioning wheel assembly; The centre position arranging guide rail, front thrust wheel and rear thrust wheel on the upside of following crawler belt arranges floating roller, and floating roller is higher than thrust wheel 0-50mm.
Further, also including carrier wheel, carrier wheel is arranged on the centre position of front tensioning wheel assembly and driving wheel, and is fixed on fixed mount.
Preferably, described rear tension assembly includes rear regulating wheel, connection fork, adjusting bolt, middle slide rail and the cuboid closed housing surrounded by cover plate, middle slide rail is positioned at closed housing, and the cover plate that a bead plate of closed housing is adjacent by bolt is fixed, it is simple to dismounting.
Preferably, described fixed mount shape triangular in shape.
Preferably, the quantity of described floating roller is 2.
Compared with prior art, the beneficial effects of the utility model:
(1) caterpillar belt structure of the present utility model is triangular structure, and this structure is effectively improved car load terrain clearance, it is ensured that the property passed through of car load;
(2) tensioning wheel assembly arranges two, ensure that the tensioning of whole crawler belt, closed housing outside post-tensioning device is detachable simultaneously, therefore middle slide rail can be directly taken out, while guarantee is easy to assembly, also effectively solves the convenience that crawler belt maintenance is removed, is effectively improved the efficiency of assembling, maintenance;
(3) in the middle of following crawler belt, two floating rollers higher than thrust wheel are set, when being mainly used in walking process running into ditch, bank or uneven road, the impact preventing two lever ratio excessive and to cause front or rear nose to produce, increases and crosses large impact when this device alleviates walking effectively;
(4) for preventing crawler belt unexpected derailing or the non-tensioning of crawler belt and sideslip of causing in the process of walking, in conjunction with the tooth bar notch of crawler belt self, above crawler belt, set up guide rail, be effectively guaranteed the properly functioning of crawler belt.
