The torsion beam semi-independent suspension structure comprises two longitudinal arms, one torsion beam and a torsion bar, wherein the two longitudinal arms are connected to the two ends of the torsion beam; each longitudinal arm is provided with a rear shaft body bracket, a shock absorber support, a spring seat and a tire bracket; the rear shaft body bracket is arranged at the upper ends of the longitudinal arms; the shock absorber support is arranged at the lower ends of the longitudinal arms; the tire bracket is arranged on the sides, away from the torsion beam, of the longitudinal arms; the torsion bar is additionally arranged on the lower side of the torsion bar torsion beam. The roll stiffness and the rolling angle stiffness of the suspension can be increased under the condition that the stiffness of the suspension is not increased, so that the integral performance of the suspension is improved.
Description
Technical field
The present invention relates to a kind of semi-independent suspension structure for torsion beam, particularly a kind of semi-independent suspension structure for torsion beam for car suspension system.
Background technology
Torsion beam semi-independent suspension is rear overhang hanging hang structure conventional at present, by the torsion beam of an overall V-arrangement or channel section the trailing arm solder together of the left and right sides, make comparatively formula in the front end of trailing arm by rubber-metal support and vehicle body to be connected, be connected with spring with wheel hub, bumper in the rear end of trailing arm.The trailing arm of torsion beam can swing up and down so that by bumper and damping spring absorbing vibration around rigid connection point, play the effect of shock-absorbing, when both sides Suspension Deformation does not wait, torsion beam twists distortion, because this torsion beam has larger elasticity, the effect of stabilizer antiroll bar can be played.Therefore torsion beam is critical component in the semi-independent suspension of torsion girder-like, and it plays power transmission, the stressed effect with being connected balance both sides, and suspension is related to Vehicle handling and traveling comfort.Because torsion beam in prior art exists roll rate deficiency, affect the situation of vehicle operating stability, therefore one is not also had can to increase torsion beam roll rate in prior art, to ensure that vehicle has the semi-independent suspension structure for torsion beam of good road-holding property in turning operating mode.
Summary of the invention
Technical matters to be solved by this invention is to provide one can increase torsion beam roll rate, to ensure that vehicle has the semi-independent suspension structure for torsion beam of good road-holding property in turning operating mode.
For solving the problems of the technologies described above the semi-independent suspension structure for torsion beam that the present invention adopts, comprise two trailing arms and a torsion beam, described two trailing arms are connected to the two ends of torsion beam, each trailing arm is provided with rear axle body support frame, vibration damping mounting, spring perch and tire support, described rear axle body support frame is arranged on the upper end of trailing arm, described vibration damping mounting is arranged on the lower end of trailing arm, and the center of gyration of vibration damping mounting is vertical with torsion beam, described spring perch is arranged on the side of trailing arm near torsion beam, described tire support is arranged on the side of trailing arm away from torsion beam, also comprise torsion bar, two ends of described torsion bar are fixedly connected with two trailing arms respectively, the axial line of described torsion bar is parallel with the center of symmetry of torsion beam.
Further, described torsion bar is hollow structure.
Further, the diameter of end that described torsion bar is connected with trailing arm is greater than the diameter of torsion bar centre portion.
Further, describedly arc transition section is also provided with in torsion bar end and centre portion.
Further, the end of described torsion bar is welded with trailing arm.
The invention has the beneficial effects as follows: because torsion beam suspension likely there will be roll rate and roll angular rigidity situation less than normal, if now directly increase spring stiffness to increase roll rate and roll angular rigidity, then spring stiffness increases, the vertical stiffness of suspension also can increase accordingly, suspension will be made so partially hard, thus affect the traveling comfort of car load.And the application increases a kind of torsion bar below torsion beam, when suspension rate need not be increased, can increase roll rate and the roll angular rigidity of suspension, thus improve the overall performance of suspension.Torsion bar adopts hollow structure greatly can alleviate suspension weight, improves the traveling comfort of car load.Because torsion bar is larger with the regional stress of junction on trailing arm, can not transition very well, easily make torsion bar rupture from here, therefore the diameter of the application end that torsion bar is connected with trailing arm is greater than the diameter of torsion bar centre portion, allows stress even transition in torsion beam.Concentrate in order to avoid end and centre portion junction produce stress, cause the situation that torsion bar ruptures from here.

Parts, position and numbering in figure: trailing arm 1, torsion beam 2, rear axle body support frame 3, vibration damping mounting 4, spring perch 5, tire support 6, end 7, torsion bar 8, centre portion 9.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figures 1 and 2, beam semi-independent suspension structure for torsion beam of the present invention, comprise two trailing arms 1 and a torsion beam 2, described two trailing arms 1 are connected to the two ends of torsion beam 2, each trailing arm 1 is provided with rear axle body support frame 3, vibration damping mounting 4, spring perch 5 and tire support 6, described rear axle body support frame 3 is arranged on the upper end of trailing arm 1, described vibration damping mounting 4 is arranged on the lower end of trailing arm 1, and the center of gyration of vibration damping mounting 4 is vertical with torsion beam 2, described spring perch 5 is arranged on the side of trailing arm 1 near torsion beam 2, described tire support 6 is arranged on the side of trailing arm 1 away from torsion beam 2, also comprise torsion bar 8, two ends 7 of described torsion bar 8 are fixedly connected with two trailing arms 1 respectively, the axial line of described torsion bar 8 is parallel with the center of symmetry of torsion beam 2.Because torsion beam suspension likely there will be roll rate and roll angular rigidity situation less than normal, if now directly increase spring stiffness to increase roll rate and roll angular rigidity, then spring stiffness increases, the vertical stiffness of suspension also can increase accordingly, suspension will be made so partially hard, thus affect the traveling comfort of car load.And the application increases a kind of torsion bar 8 below torsion beam 2, when suspension rate need not be increased, can increase roll rate and the roll angular rigidity of suspension, thus improve the overall performance of suspension.
Described torsion bar 8 is hollow structure.Torsion bar 8 adopts hollow structure greatly can alleviate suspension weight, improves the traveling comfort of car load.
The diameter of the end 7 that described torsion bar 8 is connected with trailing arm 1 is greater than the diameter of torsion bar 8 centre portion 9.Because torsion bar 8 is larger with the regional stress of junction on trailing arm 1, can not transition very well, easily make torsion bar 8 rupture from here, therefore the diameter of the application end 7 that torsion bar 8 is connected with trailing arm 1 is greater than the diameter of torsion bar 8 centre portion 9, allows stress even transition in torsion beam 2.
Describedly also be provided with arc transition section in torsion bar 8 end 7 with centre portion 9.Concentrate in order to avoid end 7 and centre portion 9 junction produce stress, cause the situation that torsion bar 8 ruptures from here.
The end 7 of described torsion bar 8 is welded with trailing arm 1.Adopt the connection mode of welding to be connected firmly, be convenient to processing.
