2. poor universality, as any one in curved rod radius bend, bending moment, length of connecting rod, node size, upper node installation angle etc.
The change of individual parameter, all may need mold again, can increase manufacturing cost and production cycle simultaneously；
3. the upper and lower nodal pitch of link assembly cannot adjust, and because of traditional vertical connecting rod global formation, size is the most shaped, nothing
Method adjusts upper and lower nodal distance.Because of wheel spinning roller cause framework to fall problem that the link assembly mounting distance that brings increases, nothing
Method meets client's continuously adjustable requirement of connecting rod nodal distance；
4. quality control is difficult, and due to the moulding process of its complexity, the corner that curved rod requires in terms of quality control is the most relatively
Many, conventional chemical compositions including raw material metal, the mechanical performance after heat treatment, and Ultrasonic Nondestructive (metal
Feed stock material quality) and magnetic powder inspection (case of surface defects of product) etc., any quality control will cause cost to increase, control
System lost efficacy to be increased the potential failure risk causing product；
5. weight is big, and because curved rod uses cast forging process global formation, its connecting rod is generally solid construction, rail traffic vehicles
Lightweight is the trend of its development, goes out at present outside system unit, and remaining product all carries out using light metal or composite to enter
The lightweight application of row material substitution, and system unit generally occupies bigger weight proportion in terms of weight, if carrying out light
The application quantified, optimizes space greatly through existing.The lightweight of vehicle by from the energy consumption run, the comfortableness taken etc. each
Aspect optimizes the performance of car load.
Therefore, how by design a kind of the most safe and reliable, versatility is high to meet the torsion bar system of customer requirement, again may be used
Reduce the production cycle, and the batches of manufacturing process of shape is problem demanding prompt solution in system unit product development process.
