Description
汽车悬架应力释放设备 技术领域 Automobile suspension stress release device
本发明涉及一种汽车悬架应力释放设备， 属于汽车制造技术领域。 背景技术 The invention relates to a vehicle suspension stress releasing device, belonging to the technical field of automobile manufacturing. Background technique
现阶段的汽车生产企业大多采用在线模拟落地打紧和整车下线通过颠簸路相结合 的两种方式来控制汽车装配过程中产生的虚假力矩和残余应力， 但针对通过扭杆进行 车高调节的这类车型， 由于前后悬架多处采用橡胶衬套的连接方式以及车高调节扭杆 刚度相对较大的缘故， 仅仅依靠现有控制方法来消除虚假力矩和残余应力的效率低， 效果较差， 已经不能适应流水线生产的需求了， 必须加强颠簸的强度和时间来进行汽 车悬架应力释放。 按照现有方式， 只能通过加大颠簸落差及加长颠簸路长度来加大颠 簸强度， 这样势必会面临现有车间面积加大、 生产规划调整等一系列问题， 增加生产 成本。 最关键的一点， 目前整车下线的流程普遍为： 燃油加注→点火启动→颠簸路→ 四轮定位， 如果加长颠簸路长度， 就会加大车辆在车间内部的排放时间， 给车间空气 质量带来了严重的污染。综上所述， 无论是从整车质量控制还是从环境污染方面考虑， 上述控制方式显然已经不能满足生产要求了。 发明内容 At present, most of the automobile production enterprises use the two methods of online simulation of landing and tightness and the whole vehicle to pass the bumpy road to control the false moment and residual stress generated during the assembly process of the automobile, but for the adjustment of the vehicle height through the torsion bar. This type of vehicle has low efficiency due to the existing control method to eliminate false torque and residual stress due to the connection of rubber bushings in the front and rear suspensions and the relatively high rigidity of the torsion bar. , has been unable to adapt to the needs of production line production, must strengthen the intensity and time of the bump to carry out the stress release of the car suspension. According to the existing method, the strength of the bumps can only be increased by increasing the bumpy gap and lengthening the bumpy road. This will inevitably face a series of problems such as an increase in the existing workshop area and adjustment of production planning, and increase production costs. The most critical point is that the current process of vehicle downline is generally: fuel injection → ignition start → bump road → four wheel alignment, if the length of the bump road is lengthened, it will increase the vehicle's internal discharge time in the workshop, give the workshop air Quality brings serious pollution. In summary, whether it is from the perspective of vehicle quality control or environmental pollution, the above control methods obviously cannot meet the production requirements.
