The coupling torsion beam 01 is a welding assembly and comprises a sleeve, a left longitudinal arm, a cross beam, a left spring seat, a left shock absorber support, a left hub shaft support, a right longitudinal arm, a right hub shaft support, a right spring seat and a right shock absorber support; the left wheel hub is connected with the left mounting bracket 06 and the right mounting bracket 07 through the bushing 05, the left mounting bracket 06 and the right mounting bracket 07 are connected and fixed on the vehicle body, and the left wheel hub and the right wheel hub are arranged on the left wheel hub shaft support and the right wheel hub shaft support on the coupling torsion beam 01.
The cross beams are various in types, and have stabilizer bars or stabilizer bars; the cross section has V shape, U shape, etc., and also has closed hydroformed I shape, V shape, etc.; along with different structures such as the cross beam, the structure of the coupling torsion beam is also different.
The lower end of the spiral spring 02 is mounted on a spring seat of the coupling torsion beam 01, and the upper end of the spiral spring 02 is connected with a vehicle body through a rubber pad 04, but the spiral spring 02 only plays an elastic role in the Z direction of the CTBA, and does not play any limitation or elastic role in the limitation of the X direction and the Y direction of the CTBA.
