摘要： The invention relates to a bogie for a rail vehicle characterized by a high lightweight construction potential. The bogie (1, 1*, 1**) according to the invention has, for primary suspension, a torsion spring system (12) in the inner volume of which a roll stabilizer having a torsion rod (11) is arranged in a torsionally movable manner. The roll stabilizer can be articulated to the car body of the rail vehicle or to the torsion spring system (12). The bogie (1, 1*, 1**) according to the invention advantageously has a particularly large installation space for built-in components.

摘要： A composite material laying structure, a composite material vehicle body, and a composite material laying method, the composite material laying structure comprising a profile provided with multiple quadrilateral cavities reinforced by lap joints after butt joint connection, the quadrilateral cavities comprising square cavities and profile cavities, and the square shape of the square cavities transitioning along the profile into the trapezoidal shape of the profile cavities. The present composite material laying structure employs the laying structure of the composite material profile and a butt joint lap-joint form.
