Detailed Description
To further explain the technical means and effects of the present invention adopted to achieve the predetermined objects, the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 and 2, the torsion beam type suspension structure of the present invention includes a torsion beam body 1, a sway arm 2 for connecting a wheel and the torsion beam body 1, a torsion beam reinforcing plate 3 provided inside the torsion beam body 1, a wheel mounting portion 4 for mounting the wheel, a spring seat 5 lapped between the torsion beam body 1 and the sway arm 2, and a damper mounting portion 6 for mounting a damper. The torsion beam body 1 comprises a beam central part 11, two beam end parts 12 and two circumference increasing parts 13 arranged on two sides of the beam central part 11 and between the beam end parts 12, the torsion beam body 1 is connected with the rocking arm 2 through the beam end parts 12, the beam central part 11 is positioned in the middle of the torsion beam body 1, the circumference increasing parts 13 are positioned between the beam central part 11 and the beam end parts 12, the beam height and the beam width of the beam end parts 12 are larger than those of the circumference increasing parts 13, and the beam height and the beam width of the circumference increasing parts 13 are larger than those of the beam central part 11.
Further, the beam height and the beam width of the beam center portion 11 and the beam height and the beam width of the beam end portion 12 are not gradually expanded and are not gradually reduced, the perimeter increasing portion 13 includes a first increasing region 131 and a second increasing region 132 which are adjacent, the first increasing region 131 is adjacent and connected to the beam center portion 11, the second increasing region 132 is adjacent and connected to the beam end portion 12, the beam width of the first increasing region 131 is gradually expanded from the beam center portion 11 to the second increasing region 132 according to a first gradually expanding ratio, the beam width of the second increasing region 132 is gradually expanded from the first increasing region 131 to the beam end portion 12 according to a second gradually expanding ratio, the beam height of the first increasing region 131 is not gradually expanded and is not gradually reduced, and the beam height of the second increasing region 132 is gradually expanded from the first increasing region 131 to the beam end portion 12 according to a fourth gradually expanding ratio.
Similarly, the beam thickness of the beam end portion 12 is larger than the beam thickness of the increased circumferential length portion 13, the beam thickness of the increased circumferential length portion 13 is larger than the beam thickness of the beam central portion 11, and the beam thickness of the increased circumferential length portion 13 is gradually increased from the beam central portion 11 to the beam end portion 12 according to a third gradual increase ratio.
Specifically, the beam center portion 11 is formed in an inverted U-shape in cross section, and the entire length of the increased circumferential length portion 13 in the circumferential direction is larger than the circumferential length of the beam center portion 11, since it is necessary to ensure that the bending strength of the torsion beam body 1 around the transverse axis gradually increases from the middle to both sides to satisfy the mounting strength required for the sway arm 2. The first divergent ratio in the present invention is significantly smaller than the second divergent ratio, and the third divergent ratio and the fourth divergent ratio are linear functions with the length distance from the beam center 11 to the beam end 12 as a variable, because if the beam width increases from the beam center 11 to the beam end in a constant manner, in order to satisfy the installation strength requirement of the beam end for the rocking arm 2 and the torsion strength requirement of the torsion beam body 1, the shape discontinuity at the boundary between the beam center 11 and the circumferential length increasing part 13 is significant, resulting in the phenomenon of stress concentration. The increased circumferential section 13 in the present invention is a first increased area 131 and a second increased area 132, which are different in gradual expansion ratio, and can suppress a rapid change in beam width and avoid a stress concentration phenomenon. In the present embodiment, the beam height in the first enlarged region 131 is approximately constant, and the beam width is gradually increased toward the beam end, so that the bending strength about the longitudinal axis is gradually increased toward the beam end at an approximately constant rate, and the beam height in the second enlarged region 132 is gradually increased toward the beam end, on the premise that the bending strength about the transverse axis of the torsion beam body 1 is not changed, so that the bending strength about the transverse axis and the longitudinal axis of the torsion beam body 1 is gradually increased toward the beam end in the second enlarged region 132. That is, the first enlarged region 131 in the present invention gives the increased circumference section 13 torsional rigidity and bending strength, and further gives the second enlarged region 132 bending strength, and avoids stress concentration by suppressing a sudden change in beam width while simultaneously achieving both lateral bending and longitudinal bending performance. In other embodiments, the perimeter increasing portion 13 may be divided into three or more increasing areas according to actual development requirements to ensure that the torsion beam achieves the expected performance.
Specifically, the torsional characteristics of a twist beam can be characterized by the torsional difficulty Ip, i.e., the equation:
Ip＝Iy+Iz；
where Iy is the bending strength around the horizontal axis and Iz is the bending strength around the vertical axis, in this embodiment, the degree of difficulty of torsion Ip of the beam center portion 11 is approximately constant, so that the torsion beam body 1 is twisted at a constant angle during actual operation, but the degree of difficulty of torsion Ip of the increased circumference portion 13 fluctuates greatly in the direction of increasing the thickness thereof, and therefore the increased circumference portion 13 is less likely to generate torsional deformation, that is, most of the torsional deformation generated by the torsion beam is borne by the beam center portion 11, and the suspension characteristics can be adjusted to some extent by adjusting the relative lengths of the beam center portion 11 and the increased circumference portion 13 or the proportion of the two torsion beam lengths. In the present embodiment, the wall thickness of the beam end portion 12 is 3.2mm, the wall thickness of the beam central portion 11 is 3.0mm, the wall thickness of the perimeter increasing portion 13 gradually changes from 3.0mm to 3.2mm, the thinner the beam central portion 11, the thicker the beam end portion 12, the length of the beam central portion 11 accounts for 5% to 20% of the length of the torsion beam body, the length of the two beam end portions 12 is the same, and the length of the two beam end portions 12 respectively accounts for 3% to 7% of the length of the torsion beam body.
Further, referring to fig. 3, the present invention also includes a method for manufacturing the torsion beam, which is used to produce the torsion beam body 1, and includes the following steps:
step S1: rolling the steel coil by using a rolling mill to prepare a differential plate;
specifically, in step S1, a steel coil of equal thickness is rolled by a rolling mill, and the steel coil is rolled while controlling the distance between the rolling rolls provided in the rolling mill so that the thickness of the steel coil varies in the longitudinal direction, whereby the thickness can be adjusted, and the long steel sheet fed from the rolling mill is cut into predetermined length units, thereby forming a differential thickness plate to be prepared in a subsequent stamping sequence, and the differential thickness plate formed by rolling the steel coil includes a width-constant portion for forming the beam central portion 11, a width-enlarged portion for forming the circumferential length-enlarged portion 13, and a large end portion for forming the beam end portion 12.
Step S2: performing U-shaped stamping on the difference thick plate by using a stamping machine to manufacture a torsion beam;
specifically, in step S2, the pressing is divided into three steps to gradually form the torsion beam, including a preforming step, a forming step, and a shaping step, in consideration of the complexity of the molding surface.
And step S3: quenching the torsion beam by using a heating device;
specifically, in step S3, the torsion beam after the press-forming is quenched using a batch-type heating apparatus, and in this embodiment, the steel coil is made of hypoeutectoid steel, and the temperature in the heating furnace is set to 850 ℃.
And step S4: and (3) performing stress relief annealing on the torsion beam by using a high-frequency induction heating device to manufacture the torsion beam body 1.
Specifically, in step S4, the high-frequency induction heating apparatus includes an induction coil for heating and a feed roller for feeding the torsion beam, and the power supply rate of the high-frequency induction heating apparatus, such as the frequency and amplitude of the alternating current and the moving speed of the torsion beam relative to the induction coil, is maintained constant, whereby the tempering can be performed relatively easily without special adjustment, and after the stress-relief tempering, the temperature of the torsion beam is cooled to room temperature to ensure the surface quality of the sample piece. In this embodiment, the quenching temperature is in the range of 800 ℃ to 900 ℃, and at least needs to be lower than the melting point and higher than the A1 transformation point, i.e. higher than 730 ℃ or higher than the A3 transformation point, i.e. higher than 750 ℃ to 900 ℃, so as to obtain the martensite structure with ideal properties. The stress relief annealing temperature is in the range of 550-650 ℃, and the stress relief annealing is carried out after quenching and heat preservation for 30 minutes to obtain a sorbite structure, so that the toughness of the torsion beam is improved. In particular, since the thickness of the beam center portion 11 is smaller than that of the beam end portion 12, and the circumference of the beam center portion 11 is smaller than that of the beam end portion 12, the heat capacity of the beam center portion 11 is smaller than that of the beam end portion 12, and the annealing temperatures of the beam center portion 11 and the beam end portion 12 are different. In this embodiment, since the annealing temperature of the beam center portion 11 is higher than that of the beam end portion 12, and the heat generation per unit length of the torsion beam is the same on the premise that the induction coil power is the same, the temperature rise of the beam center portion 11 is higher than that of the beam end portion 12, the target heating temperature of the beam center portion 11 is 600 ℃, and the heating temperature of the beam end portion 12 is 550 ℃, the sorbite having high toughness is easily formed in the beam center portion 11, and the troostite having high hardness is easily formed in the beam end portion 12, which is advantageous for improving the durability and the torsion characteristics of the torsion beam. In other embodiments, the performance of the torsion beam can be adjusted by adjusting the power supply rate and the moving speed of the torsion beam relative to the induction coil according to actual development requirements, or by changing the amount of heat applied to the beam center portion 11 and the beam end portion 12.
In summary, the torsion beam type suspension structure of the present invention improves durability and torsion characteristics of the torsion beam by designing the beam width, beam thickness, and beam height of the beam center portion, the perimeter increasing portion, and the beam end portion of the torsion beam body, and avoiding stress concentration by suppressing a rapid change in the beam width while taking both lateral bending and longitudinal bending properties into consideration.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
