Description
Technical field
The invention belongs to rail traffic vehicles bogie technique fields, and in particular to one kind having small curve negotiation ability
The shared non-powered of the high two neighboring car body of floor light rail vehicle of six axis among articulation steering frame.
Background technology
Existing large and medium-sized railcar generally requires main line track smallest curve radius between 300-350 meters, uses
All steel wheel, axis weigh 14 tons to 16 tons or so, and freight volume is big, noise is big, construction cost is high, is not suitable for overhead road of city and ground
Circuit is run, therefore should not be as the backbone track vehicle of small and medium-sized cities.And the high floor light rail vehicle of six axis, using rubber
Elastic wheel, axis focus on 10.5 tons to 12.5 tons or so, can reduce line construction by 25 to 50 meters of sinusoids radius
Engineering amount of demolition.Simultaneously as the lower axis of vehicle is heavy and uses rubber elastic wheels, wheel-rail noise is relatively low, can be in city
City's aerial conveyor and the operation of ground rail circuit, had not only maintained the technological merit of steel wheel-rail Rail Transit System, but also can avoid
The technical vulnerability of the traffic systems such as rubber wheel single track, middle low speed magnetic suspension, therefore handed over as backbone track in external small and medium-sized cities
Way system is still widely used.
Currently, China does not have both without the high floor light rail vehicle application of small-sized four axis with small curve negotiation ability yet
The high floor light rail vehicle application of six axis.Using the high floor light rail vehicle of six axis of rubber elastic wheels, 25 to 50 meters can be passed through
Small curve, and have lower wheel-rail noise, compared with the small-sized high floor car of four axis with equivalent technology, six axis
High floor light rail car reduces the bogie total quantity of train under the conditions of making full use of the static shaft weight of track permission, can also pass through
It is multigroup even to hang operation raising freight volume, it can realize subway as the low cost backbone Rail Transit System of small and medium-sized cities completely
The three-dimensional in road, elevated line and ground line is run, and unmanned subway or suburbs commuting electricity are either used as external
Che Junyou is applied.
In addition, articulation steering frame uses revolution between domestic six axis developed are hinged high two car body of floor light rail vehicle
Bearing realize bogie and car body connection, not only steering resistance size is uncontrollable, and it is of high cost, weight is big, need to turntable
Bearing periodically injects lubricating grease；In addition, eight systems among the high floor light rail car of six axis of the prior art on articulation steering frame
Spring is provided separately, and not in approximately the same plane, the anufacturability and strength reliability of bogie frame are poor；And
Articulation steering frame uses solid axle among the high floor light rail car of six axis, cannot achieve and periodically carries out ultrasonic examination inspection to axle
It looks into.
