Description
Technical field
The utility model is a kind of novel steering frame run for city (particularly mountain city) track traffic light rail train, by the optimization to existing city rail bogie truck, to solve the problem that light rail train climbing difficulty is built in mountain city, reduce the wheel-rail wear of vehicle to greatest extent.
Background technology
bogie truck is one of the most key parts of guideway vehicle, and for the carrying of train, braking, traction, the demand such as to turn to.
Along with the quickening of Urbanization in China, the congested problem of city traffic has become one of difficult problem that domestic many big and medium-sized cities face.Light rail is subject to urban construction person favor due to advantages such as the occupation of land of himself is little, cost is low, energy consumption is low, environmental protection becomes the main mode of transportation in city gradually.But some are positioned at the city of mountain area, high-land, owing to being subject to the restriction of himself landform reason, building city rail traffic route is more difficult thing, and major cause is that the gradient of many mountain regions section is large, relies on traditional wheel-rail contact relationship cannot solve the problem of train climb very steep slopes.And traditional Bogie Designs structure can make train when turning, and can produce the wearing and tearing of a certain amount of wheel track.Long term accumulation, rail and wheel are by generation abrasion and peel off.This will bring huge property damage and potential safety hazard to railway systems.Authority according to railway main office adds up, China's domestic wheel examine and replace expense reach 3,600,000,000 yuan/annual, change rail Fei Keda 5,000,000,000 yuan/annual.
Based on above-mentioned realistic background present situation, we will design a Novel Light-Rail bogie truck, to solve current Problems existing.
Summary of the invention
Build the serious problem of the low and Ackermann steer angle wheel-rail wear and tear of light rail train hill climbing ability for overcoming mountain city, the utility model provides and a kind ofly adopts independently rotating wheel and be provided with the novel city rail bogie truck of auxiliary climbing rubber wheel.
It is the cement pavement of level in the middle part of the track that this product mainly utilizes light rail train, there is certain width, there is no the feature of sleeper, mounting strap power rubber wheel (friction coefficient of rubber and cement pavement is much larger than taking turns the friction coefficient with rail) on bogie truck, improves the hill climbing ability of urban light rail by the friction of rubber tire and cement pavement.In addition, adopt the design of independently rotating wheel, train can being made in the effect by forming " differential " during curve, significantly reducing wheel-rail wear and tear.
The technical scheme that the utility model adopts is: truck frame mainly forms " order " glyph framework structure by curb girder, crossbeam and end carriage.Curb girder is the box section structure become by Plate Welding, and it is welded with the parts such as damper base, primary spring seat, secondary spring seat and horizontal backstop, crossbeam and curb girder are cylindricality section structures, it are welded with axlebox rod seat, sweep the parts such as stone implement flap seat.Bogie fixed wheelbase is 2840mm, and wheel adopts Steel material, and diameter is 840mm, and wheel tread type is LM type Abrasion performance tread.Independently rotating wheel adopts two pivoted arm axle-box locating, the overall axle journal position being positioned at steel wheel axletree of axle box assembling, bearing and axle journal interference fit, and journal box body is arranged on bearing and is connected with crossbeam, thus reaches wheel and independently rotate, and alleviates the object of wheel-rail wear and tear.Accessory device mainly comprises sweeps stone implement, derailing steel plate, backstop etc.Sweep stone implement device primarily of sweeping stone implement support, sweep stone implement aluminium sheet, the composition such as stone deflector rubber plate, rubber assembling steel plate, sweeping stone implement is arranged on end carriage, is positioned at the forward position of steel wheel.Derailing steel plate, primarily of steel plate, fixed bearing composition, is arranged on axle box.In addition, between two crossbeams of bogie truck, axletree is installed at position, and rubber wheel and axletree interference fit, axletree is fixed by the cylindrical bearing and axle box being arranged on axle journal two ends.In the process of moving, rubber wheel is driven by the motor that is arranged on below car body train, the traction friction force produced according to rubber wheel and cement flooring, make light rail can in mountain area, terrain that hills uniform slope is larger.
Compared with prior art, the beneficial effects of the utility model are:
(1) rubber wheel of mounting strap power between bogie truck diaxon, utilizes the friction force of rubber wheel and cement pavement, improves the hill climbing ability of light rail.
(2) difference that this product is maximum with prior art is exactly the installation of abandoning steel wheel and the axletree interference fit adopted at present, but adopts independently rotating wheel, making light rail by forming differential effect during curve, alleviating the wearing and tearing between wheel track.
(3) be arranged on the derailing steel plate inside steel wheel, when derail, steel plate can fetter the transverse shifting of bogie truck, thus ensures that train runs in certain safe level.
(4) be arranged on the pilot (be commonly called as and sweep stone implement) at bogie truck two ends, by presenting certain angle with rail level, the foreign matter removing rail level can be helped, thus ensure that the safety traffic of light rail.
