Still through the both ends welding fixed plate at the stabilizer bar to through fixed plate and trailing arm welding, improved the welded area, and then reduced the stress concentration of welding position, the diaphragm both sides on the fixed plate set up the flange of leanin and the notch groove of flange and riser formation can guarantee that the girder takes place when deformation, cushion through producing elastic deformation when playing the effect of support.
The invention has the beneficial effects that:
1. through the connecting plate of welding L type between trailing arm and girder, shift the weak link of girder and trailing arm to the welding position of connecting plate by mutual welding position, through increase welded area for stress distribution is even, is difficult for taking place stress concentration.
2. Through at stabilizer bar both ends welding fixed plate, through the fixed plate respectively with girder and both sides trailing arm welding, when improving the connection reliability of stabilizer bar, improve the shock-absorbing capacity of torsion beam rear axle.
3. The sleeve installed at one end of the longitudinal arm is turned over towards the end part on one side of the main beam, so that deformation of the sleeve is reduced when the torsion beam rear axle deforms, and pressure of the bushing is further improved to 15kN from 8 kN.
4. Through set up the stopper in the middle of the girder is inside, carry on spacingly for stable deformation through the stopper, can guarantee that the stabilizer bar when taking place deformation, can not send the noise because of the contact with the girder inner wall.
