In this application, a suspension damper with dual stiffness structure is proposed, which can improve the isolation and support performance of the decoupled damper. The application includes a middle support plate and a support sleeve, the middle support plate is respectively connected with the upper and lower connecting plates, and a leather bowl is arranged between the support sleeve and the middle support plate, the end of the middle support plate is respectively connected with the upper and lower buffer rubber, the other end of the upper buffer rubber is connected with the upper limit plate, the other end of the lower buffer rubber is connected with the lower limit plate, and the upper bowl is provided with an inertia channel and an inertia channel. The lower part is provided with a liquid inlet and the upper part is provided with a liquid outlet. The cavity between the leather bowl and the upper limit plate and the upper buffer rubber forms a lower pressure liquid chamber, and the cavity between the leather bowl and the lower limit plate and the lower buffer rubber forms an upper pressure liquid chamber. This application takes the upper and lower cushioning rubber parts as the main vibration isolation function when small deformation occurs, and the upper and lower cushioning rubber structures deform and compress the volume of the upper and lower pressure liquid chambers when large deformation occurs, thus providing higher stiffness to support them when large deformation occurs.

一种双刚度结构的悬架减振器
本技术属于汽车减振领域,具体涉及一种汽车悬架减振装置。
技术介绍
悬架减振器TOPMOUNT作为汽车悬架减振与车身连接的关键零部件,其主要功能是隔离汽车减振器传递的来自路面激励产生的振动和噪声,对整车NVH和乘坐舒适度有着很大的影响。原有的减振器TOPMOUNT产品分为承载式和解耦式,承载式因为需要承载整车质量所以刚度较高,隔振性能很差,解耦式虽然将承载通道和隔振通道进行了隔离解耦,但是隔振通道的低刚度带来的是可靠性的降低和操控性能的下降,如何让解耦式TOPMOUNT更好的隔振和支撑成为了技术关键。
技术实现思路
本技术提出一种双刚度结构的悬架减振器,能够提供解耦式减振器的隔振和支撑性能。本技术的技术方案是这样实现的:一种双刚度结构的悬架减振器,包括中部支撑板和支撑套管,中部支撑板上方与上连接板相连、下方与下连接板相连,支撑套管与中部支撑板之间设有皮碗,中部支撑板端部分别与上缓冲橡胶、下缓冲橡胶相连,上缓冲橡胶另一端与上限位板相连,下缓冲橡胶另一端与下限位板相连,皮碗上设有惯性通道,惯性通道下方设有进液口、上方设有出液口,皮碗与上限位板、上缓冲 ...
