Abstract
A kind of power truck of 100% low-floor light rail vehicle traditional wheelsets form, comprising frame apparatus, taking turns composition, primary spring, secondary spring, two be vertical damper, two be lateral damper, two is horizontal buffer, single traction rod, anti-side rolling torsion rod, elastic suspension longitudinal driving device, hydraulic brake unit and electromagnetic rail brake, it is characterized in that: take turns and wheel shaft type structure is adopted to composition, axle box is built-in, wheel adopts Φ 500mm-Φ 580mm diameter elastic wheel, is provided with two cover anti-side rolling torsion rods at cross rail outer.This steering framing wheel adopts wheel shaft type structure to composition, and axle box is built-in, and wheel adopts Φ 500mm-Φ 580mm diameter elastic wheel, solves the guiding problem of wheel when the right recovery problem of linear running hour wheel and curve motion; At cross rail outer, two cover anti-side rolling torsion rods are installed, improve vehicle anti-rolling performance.While this bogie truck successfully realizes the requirement of car body 100% low floor, simplify the structure of bogie truck, all parts all adopt ripe product, are beneficial to the modular design of bogie truck.
Description
Technical field
The utility model relates to 100% low-floor light rail vehicle power truck.
Background technology
What the representative bogie truck of the bogie truck of 100% low floor vehicle adopted is mechanism of independent wheel structure, and drive arrangement, in framework both sides, uses the mode of axle bridge to reduce floor level.A set of actuating device drives former and later two wheels simultaneously.There is following two problems in independent wheel bogie: the guiding problem of wheel when the recovery problem that linear running hour wheel is right and curve motion, and this two problems is difficult to solve in independent wheel bogie.Existing conventional rigid d-axis wheel is right, and due to limited space under car, for ensureing vehicle displacement requirement, often the design of spring vertical stiffness is very large, and traveling comfort is deteriorated, and vehicle anti-rolling performance declines.
Utility model content
Technical problem to be solved in the utility model is the requirement how utilizing the bogie truck of traditional wheelsets to realize vehicle 100% low floor.
For solving the problems of the technologies described above, the utility model provides a kind of power truck of 100% low-floor light rail vehicle traditional wheelsets form, comprise frame apparatus, wheel is to composition, primary spring, secondary spring, two is vertical damper, two is lateral damper, two is horizontal buffer, single traction rod, anti-side rolling torsion rod, elastic suspension longitudinal driving device, hydraulic brake unit and electromagnetic rail brake, it is characterized in that: take turns and wheel shaft type structure is adopted to composition, axle box is built-in, wheel adopts Φ 500mm-Φ 580mm diameter elastic wheel, at cross rail outer, two cover anti-side rolling torsion rods are installed.
This steering framing wheel adopts wheel shaft type structure to composition, and axle box is built-in, and wheel adopts Φ 500mm-Φ 580mm diameter elastic wheel, solves the guiding problem of wheel when the right recovery problem of linear running hour wheel and curve motion; At cross rail outer, two cover anti-side rolling torsion rods are installed, improve vehicle anti-rolling performance.While this bogie truck successfully realizes the requirement of car body 100% low floor, simplify the structure of bogie truck, all parts all adopt ripe product, are beneficial to the modular design of bogie truck.Simultaneously for existing rigidity d-axis wheel is to the solution of the renewal that formula bogie truck raising traveling comfort provides.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model;
Fig. 2 upward view of the present utility model.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, bogie truck of the present utility model forms by with lower part: framework 1, take turns forming 2, primary spring 3, secondary spring 4, two be vertical damper 5, two be lateral damper 6, two be horizontal buffer 7, single traction rod 8, anti-side rolling torsion rod 9, elastic suspension longitudinal driving device 10, hydraulic brake unit 11 and electromagnetic rail brake 12.Take turns and adopt wheel shaft type structure to composition, axle box is built-in, and wheel adopts Φ 500mm-Φ 580mm diameter elastic wheel.At cross rail outer, two cover anti-side rolling torsion rods are installed.
Taking turns the height of axletree is the critical component realizing the reduction of car body floor face, and the use of Φ 500mm-Φ 580mm diameter elastic wheel, makes the height reduction of axletree, provides space for realizing the reduction of car body floor face.Elastic wheel has the effect of vibration and noise reducing simultaneously.
The setting of torsion bar mechanism for preventing side rolling of train carriage, improves the anti-rolling performance of vehicle, makes the reduction of secondary spring vertical stiffness become possibility, improves the dynamic performance of vehicle.
