Rail traffic vehicles anti-rolling torsion bar system between frame, belongs to mechanical engineering technical field.
Technical background
Anti-rolling torsion bar system (abbreviation torsion bar system) is rail traffic vehicles (including main line railway vehicle, subway urban rail
Vehicle, tramcar etc.) critical component, for inhibiting the car body when vehicle turning, crosswind to sidewinder, torsion bar system
By vertical link assembly, torsion arm supports holder assembly and torsion bar shaft composition.With running velocity and its riding comfort
It is required that raising, to torsion bar system and rail traffic vehicles system unit (such as hanging connecting rod component, positioning arm component etc.)
It is also proposed that increasingly higher demands, wherein lightweight is one of technology trends.
The vehicle of usual torsion bar system divides into built-in and two kinds of types of external according to the different of its arrangement
Formula, wherein built-in torsion bar system is arranged in the inside of bogie crossbeam, the length of torsion bar shaft is 1300-1800mm, torsion bar
The weight of system about 120-150kg, external torsion bar system are arranged in the outside of bogie crossbeam, and the length of torsion bar shaft is
1800-2500mm, the weight 150-220kg of torsion bar system.
Outside the least a portion of metal rubber piece of component depolarization or high molecular material in torsion bar system, remaining metal portion
The weight of part accounts for 95% or more.Under the premise of current technology scheme, support base can only be optimized by torsion bar shaft village hollowing
Mitigate the weight of torsion bar system with modes such as torsion arm configurations, but there are biggish limitation, diminishbb weight range is less than
10%.The interior trim of rail traffic vehicles, the components such as car body use light metal alloy (aluminium alloy, magnesium alloy etc.) one after another, and macromolecule is multiple
The means such as condensation material constantly to reduce the weight of vehicle, therefore, how by selecting other non-metallic components to manufacture torsion bar system
System, and the batches of manufacturing process of shape and quality control method are urgently to be resolved in system unit product development process ask
Topic.
The torsion bar system based on metal parts is used to be primarily present following defect at present:
1. manufacturing cost is high, due to the raw material of metal parts and the limitation of moulding process, manufacturing cost is relatively high, with
Few using dosage for torsion bar shaft, intensity is high, the original of the spring steel material of the 52CrMoV4 acc EN 10089 of high-hardenability
Material cost is higher, and secondly the moulding process of torsion bar shaft includes end jumping-up, is machined, heat treatment, and shot blasting on surface etc. is various
Process, further includes ultrasonic examination, the nondestructiving detecting means such as magnetic powder inspection, and complex process leads to higher cost；
2. mass control is difficult, due to its complicated moulding process, each component of torsion bar system requires in terms of quality control
Corner it is also relatively more, common includes the chemical component of raw material metal, and the mechanical performance after heat treatment embodies its through hardening
Property outside and core hardness determination and Ultrasonic Nondestructive (raw material metal internal soundness) and magnetic powder inspection (produce
The case of surface defects of product) etc., any quality control will lead to cost, and control failure will lead to the potential failure risk of product
's；
3. weight is high, the lightweight of rail traffic vehicles is the trend of its development, is gone out outside system unit at present, remaining product
The lightweight application that material substitution is carried out using light metal or composite material is carried out, and system unit is usually in terms of weight
Occupy biggish weight proportion, such as can be carried out light-weighted application, there is greatly optimization space.The lightweight of vehicle will be from
The energy consumption of operation, the various aspects such as comfort of seating optimize the performance of vehicle.
