Detailed description of the invention
The present invention is as shown in Fig. 1,2,3,4,5.
A kind of torsion bar suspension connecting device, comprise swing arm 6 and vehicle frame 8, the outside of swing arm 6 is vehicle frames 8, and one end of swing arm 6 is provided with Internal Spherical Surface and swing arm lid 4 cooperation is fixed on a beaded support 7, and the side of beaded support 7 is fixedly connected with on carriage 8; The opposite side of swing arm 6 and swing arm lid 4 is connected with cross axle sleeve 1, is provided with sleeve pipe 14 in cross axle sleeve 1, and sleeve pipe 14 inner sleeve has torsion bar spring 5; Be provided with through hole 10 in beaded support 7, torsion bar torsion spring 5 passes through from the through hole 10 of beaded support 7.
Swing arm 6 and be provided with crossover sub 3 between swing arm lid 4 and cross axle sleeve 1, wherein crossover sub 3 is located by connecting on on the connecting end surface of swing arm 6, swing arm lid 4.
Be provided with between described crossover sub 3 and swing arm 6, swing arm lid 4 with the use of cross boss 11 and cross recess 1, the other end of crossover sub 3 is provided with cross recess 2 13, is connected by slide block component 2 with cross axle sleeve 1.
Through hole 10 in beaded support 7 is eccentric orfice, and its deflection angle is 0-15 °.
Be connected by spline or six square toes, cubic first-class various ways with torsion bar spring 5 in cross axle sleeve 1.
The outside of cross axle sleeve 1 and crossover sub 3 is provided with dust protecting cap 9.
The sleeve pipe 14 of cross axle sleeve 1 stretches out.
Constructional feature of the present invention: swing arm 6 and the swing arm lid 2 of band Internal Spherical Surface are fixed on beaded support 7, guarantee whenever swing arm is all that Internal Spherical Surface is stressed, crossover sub 3 and swing arm 6 coupling end wear cross boss 11, and be pressed in the cross recess 1 of swing arm 6 and swing arm lid 4, swing torque transmits primarily of cross boss 11, separately be bolted on swing arm 6 and swing arm lid 4, the other end of crossover sub 3 wears cross recess 2 13, the slide block component 2 be connected with cross axle sleeve 1, can slide axially in the cross recess 2 13 of crossover sub 3, cross axle sleeve 1 and torsion bar spring 5 are by spline or six square toes, square head connects, the side force of such swing arm 6 can not be delivered in torsion bar spring 5.
When swing arm 6 is by side force, swing arm 6 along center of oscillation teeter, because slide block component 2 has enough activity spaces in the chute of crossover sub 3, thus can not affect transmission swing torque.The full swing amount of swing arm 6 depends on the size of slide block component 2 activity space, and the maximum yaw being equivalent to swing arm 6 moves as positive and negative 5 degree.During actual use, the teeter of swing arm 6 is very critical, the teeter amount of such swing arm 6 just can be married again in the asymmetric arrangement of torsion bar spring 5, the hole size of adding beaded support 7 does by the size of torsion bar spring 5 coupling end, make the maximum angle of torsion bar spring 5 line of centers and center of oscillation line can reach more than 20 degree, so just when center of oscillation is arranged symmetrically with, the asymmetric arrangement of torsion bar spring 5 can be realized easily.
Cross axle sleeve 1 can rotate in slide block component 2, changes cross recess 2 13 size, namely changes the activity space size of slide block component 2, can change the maximum asymmetric arrangement angle of torsion bar spring 5.
As shown in Figure 6, change the distance of cross axle sleeve 1 center-point and axle sleeve 14 end face, namely extend the length of sleeve pipe 14, just can change the effective length of torsion bar spring 5.
If need torsion bar spring 5 suitably by curved, such as present widely used Panhard rod, can be realized by the offset changing excessive coupling axis line and center of oscillation.
Beaded support 7 is connected by the bolt hole that bolt hole is corresponding with in vehicle frame 8 or frame, and locate by seam and bear from the load on spherical outside surface, swing arm 6 is contained on spherical outside surface.
Crossover sub 3 is connected with the cross recess 1 in swing arm by cross boss 11, and is connected fastening by 4 screws with swing arm 6, and Internal Spherical Surface is with by cross boss 11, to guarantee not interfere with the spherical outside surface of beaded support 7.Another of crossover sub 3 wears cross recess 2 13, coordinates with the slide block component 2 on cross axle sleeve 1.
On cross axle sleeve 1, cover has slide block component 2, and slide block component 2 slides and transmits torque to center cross in crossover sub 3 cross recess 2 13, between slide block component 2 and cross axle sleeve 1, also has a non-maintaining lining, plays a part to protect center cross.
Center cross plane can be also that acute angle is arranged with axle sleeve axis in addition, and the size of acute angle depends on the distortion angle of torsion bar spring 5 lateral arrangement.
Cross axle sleeve 1 is connected with torsion bar spring 5, and connection mode has spline, six square toes, and four directions is first-class.
Sleeve pipe in cross axle sleeve 1 can extend as required, just can change the effective length of torsion bar spring 5.
