具体实施方式Detailed ways
下面结合附图和具体实施方式对本发明作进一步说明。The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
如图1、图2、图3、图4、图5所示，一种复合材料横向稳定杆，形状呈U形，其杆身4的横截面为圆形；横向稳定杆的杆身4包括中心层3和包裹在中心层3外的一层或多层包裹层；所述包裹层由增强纤维编织而成的复合材料组成。As shown in Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, a composite material stabilizer bar has a U-shaped shape, and the cross section of its shaft 4 is circular; the shaft 4 of the stabilizer bar includes The
由于横向稳定杆的最外表面的受力条件最为恶劣，因此最外包裹层1中的复合材料内增强纤维编织方式采取平纹编织方式，即经向和纬向的增强纤维交叉编织形成平纹布6；这种平纹布6不但可以保证杆身4的强度，而且能使杆身4通过整体编织的增强纤维包覆起来，进而增强杆身4的疲劳寿命及抗冲击性能。Since the stress condition on the outermost surface of the lateral stabilizer bar is the worst, the weaving method of the inner reinforcing fibers of the composite material in the
如图2、图4所示，为了使横向稳定杆具有最佳的抗扭转性能及疲劳可靠性，因此在最外包裹层1的内侧添加一层中间包裹层2，形成两层包裹层，包裹在中心层3外，其中，中间包裹层2中的复合材料内增强纤维编织方式为单向编织，即增强纤维单向排列形成单向布7。As shown in Figure 2 and Figure 4, in order to make the stabilizer bar have the best torsion resistance and fatigue reliability, an
根据材料力学，扭转变形条件下，当增强纤维排布方向与杆身4轴线呈一锐角时，该锐角范围在30°至60°之间，尤其是当锐角角度为45°时，能充分发挥增强纤维高强度、高模量特性，因此平纹布6的经向和纬向增强纤维与杆身4轴线呈45°，单向布7的增强纤维排布方向与杆身4轴线呈45°。According to material mechanics, under the condition of torsional deformation, when the arrangement direction of the reinforcing fibers forms an acute angle with the axis of the shaft 4, the acute angle ranges from 30° to 60°, especially when the acute angle is 45°, it can give full play to the The reinforcing fibers have high strength and high modulus, so the warp and weft reinforcing fibers of the
根据使用环境所要求横向稳定杆的强度及疲劳寿命，选择横向稳定杆中处于中心位置的中心层3是否填充。According to the strength and fatigue life of the stabilizer bar required by the use environment, choose whether to fill the
当横向稳定杆用于大型SUV车型等载荷较大的车型中时，为了提高横向稳定杆的抗扭转能力和疲劳寿命，则其处于中心位置的中心层3需要填充，此时该横向稳定杆为实心结构；该中心层3选择为具有一定弹性的聚氨酯或橡胶材料，利用聚氨酯或橡胶材料的弹性变形，协调复合材料杆身4的内部变形，从而提高复合材料杆身4的抗扭转能力及疲劳寿命。When the stabilizer bar is used in a vehicle with a large load such as a large SUV, in order to improve the torsion resistance and fatigue life of the stabilizer bar, the
如图4、图5所示，当横向稳定杆用于载荷较小的小型车型时，在满足轻度和使用寿命的腔体下，为了提高总成的轻量化性能，则其处于中心位置的中心层3无需填充，此时该横向稳定杆为空心结构。As shown in Figure 4 and Figure 5, when the stabilizer bar is used for small vehicles with a small load, in order to improve the lightweight performance of the assembly under the cavity that meets the lightness and service life, it is located in the center position. The
部分车型的金属横向稳定杆出于可靠性的考虑，杆身4末端未设置接头结构，直接利用一段弯折的杆身4通过橡胶衬套与车架连接点连接。在这种情况下，直接将全部杆身4用复合材料制作即可。然而，如图1所示，部分车型的金属横向稳定杆末端采用开孔结构，通过橡胶垫或球头销与悬架导向臂连接，此时拟替换的复合材料横向稳定杆杆身4末端不可避免地需要设计开孔接头结构，而开孔部位是复合材料稳定杆杆身4的薄弱区域，因此需针对此应用场景中的横向稳定杆两端接头结构进行重点设计。For the sake of reliability, the metal stabilizer bar of some models does not have a joint structure at the end of the rod body 4, and a section of the bent rod body 4 is directly connected to the frame connection point through a rubber bushing. In this case, all the shafts 4 may be directly made of the composite material. However, as shown in Figure 1, the metal stabilizer bar end of some models adopts an open-hole structure and is connected to the suspension guide arm through a rubber pad or ball stud. At this time, the end of the composite stabilizer bar shaft 4 to be replaced cannot be used. It is avoided to design the opening joint structure, and the opening part is the weak area of the composite stabilizer bar shaft 4, so it is necessary to focus on the design of the joint structure at both ends of the stabilizer bar in this application scenario.
如图6、图7、图8所示，针对此问题，发明的横向稳定杆两末端头连接有转换接头5，其中杆身4上设置有内花键，转换接头5上设置有外花键，内外花键配合，使得两者连接。其中，复合材料杆身4末端设花键处的铺层方案不变，并保持该区域与杆身4其他铺层增强纤维的连续性，以保证接头载荷的可靠传递。在此前提下，在杆身4末端的中心层3外引入强芯毡等强化物，以填充杆身4末端凸出的花键，强芯毡等强化物外被杆身4的包裹层铺层包覆，这样既可形成杆身4花键的几何结构，也可保证花键的载荷通过连续增强纤维传递，进而保证接头连接的可靠性。为保证结构的整体强度和可靠性，设计过程中还需对接头进行强度校核和可靠性分析。As shown in Figure 6, Figure 7, Figure 8, in response to this problem, the two ends of the stabilizer bar of the invention are connected with
所述复合材料横向稳定杆杆身4通过如下工艺制备：The composite stabilizer bar shaft 4 is prepared by the following process:
一、根据设计的横向稳定杆尺寸形状，制备横向稳定杆预成型体。1. According to the designed size and shape of the stabilizer bar, prepare the stabilizer bar preform.
①根据设计需要，制备横向稳定杆各组件。① Prepare each component of the stabilizer bar according to the design requirements.
根据设计需要，裁切用于制作包裹层的不同编织方式的增强纤维预浸料，增强纤维预浸料为增强纤维编织而成的复合材料的半制品；将增强纤维预浸料裁切为与复合材料横向稳定杆的铺层长度、宽度相适应的形状，即其宽度与复合材料横向稳定杆轴线长度相同，长度与复合材料横向稳定杆的铺层层数有关，而铺层层数由复合材料横向稳定杆的刚度决定。According to the design needs, cut the reinforcing fiber prepreg used to make the wrapping layer with different weaving methods, and the reinforcing fiber prepreg is a semi-product of the composite material woven by the reinforcing fiber; The shape of the layer length and width of the composite stabilizer bar, that is, its width is the same as the axis length of the composite stabilizer bar, and the length is related to the number of layers of the composite stabilizer bar, and the number of layers is determined by the composite stabilizer bar. Material The stiffness of the stabilizer bar determines.
根据设计需要，准备用于制作横向稳定杆中心层3材料棒：其中，横向稳定杆为实心结构，则用聚氨酯棒或橡胶棒作为其中心层3填充；横向稳定杆为空心结构，则用可溶性材料作为中心层3填充。According to the design needs, prepare the material rod for making the
如果稳定杆设计花键，则裁切用于制作花键的强芯毡，其规格根据花键空腔的填充需要确定。If the stabilizer bar is designed with splines, cut the strong core felt used to make the splines, and its specifications are determined according to the filling needs of the spline cavities.
注意如果横向稳定杆末端设计有转换接头5，则中心层3材料棒的总长度短于杆身4芯轴长度，从而为花键接头成型提供操作空间。Note that if the end of the stabilizer bar is designed with a transition joint 5, the overall length of the material rod of the
②根据设计需要，拼接横向稳定杆各组件。② According to the design requirements, splicing the components of the lateral stabilizer bar.
根据需要，拼接横向稳定杆杆身4：将裁切后的不同编织方式的增强纤维预浸料依次由内而外的卷曲包裹在预先准备的中心层3材料棒上，形成横向稳定杆预成型体，并用绑带扎节以防止预成型体散开。Splicing the stabilizer bar shaft 4 as needed: The reinforced fiber prepregs of different weaving methods after cutting are rolled and wrapped on the
③如果稳定杆设计花键，则拼接横向稳定杆末端的花键结构。将预先裁切好的强芯毡等强化物插入预成型体末端的铺层内部。由于预成型体末端的铺层为确定的，因此需引入尼龙制作的花键成型骨架将强芯毡及原有铺层撑起，以形成花键形状。为防止端部铺层撑起影响杆身4整体铺层状态，在拟形成花键区域边界处用高强度绑带扎节，该绑带随预成型体一起固化在复合材料杆身4中。③ If the stabilizer bar is designed with splines, splice the spline structure at the end of the stabilizer bar. Reinforcement such as pre-cut core felt is inserted inside the layup at the end of the preform. Since the layup at the end of the preform is definite, a spline forming skeleton made of nylon needs to be introduced to support the strong core felt and the original layup to form a spline shape. In order to prevent the end laminations from affecting the overall lamination state of the shaft 4, high-strength straps are used to bind the joints at the boundary of the spline area to be formed, and the straps are cured in the composite shaft 4 together with the preform.
二、固化横向稳定杆成型。2. Curing the stabilizer bar molding.
①横向稳定杆预成型体置入模具。①The stabilizer bar preform is placed in the mold.

②模具内注入树脂。②Inject resin into the mold.
将外模合模，向模具内进一步注射树脂，使树脂充分浸润预成型体，并根据所选树脂的固化曲线选取合适的温度及模具压力，使复合材料横向稳定杆固化成型。The outer mold is closed, and resin is further injected into the mold to fully infiltrate the preform, and the appropriate temperature and mold pressure are selected according to the curing curve of the selected resin to cure the composite stabilizer bar.
三、横向稳定杆后固化及后处理。3. Post-curing and post-processing of the stabilizer bar.
①脱模固化。①Release and curing.
在复合材料横向稳定杆完成固化成型并脱模后，将其放入恒温箱内，在120℃温度下后固化2小时。After the composite stabilizer bar is cured and molded and demolded, it is placed in a constant temperature oven and post-cured at a temperature of 120° C. for 2 hours.
②横向稳定杆打磨。②The stabilizer bar is polished.
在完成后固化处理后，对其进行去毛刺及打磨处理。After the post-curing treatment is completed, it is deburred and sanded.
对涉及可溶性结构的复合材料杆身4形式，杆身为空心结构时，进行化学试剂融溶处理，以将杆身4内部的可溶性结构溶解掉，制得最终复合材料横向稳定杆杆身4。For the form of the composite material shaft 4 involving a soluble structure, when the shaft is a hollow structure, a chemical reagent melting treatment is performed to dissolve the soluble structure inside the shaft 4, and the final composite material lateral stabilizer shaft 4 is obtained.
四、如果稳定杆连接有花键，则根据设计需要，制备并装配转接接头。4. If the stabilizer bar is connected with splines, prepare and assemble the adapter according to the design requirements.
①制备转换接头5。① Prepare the
通过压铸、机械加工、热处理等手段制备金属转接接头。The metal adapter is prepared by means of die casting, machining, heat treatment, etc.
②装配转换接头5。② Assemble the
