The invention relates to the technical field of heavy truck plate spring systems, in particular to a rubber supporting structure for a plate spring, which comprises a plate spring and a plate spring end support, the plate spring comprises a plate spring end and a plate spring middle part, the plate spring end support is arranged at the plate spring end and comprises a cavity enclosed by an upper end cover and a lower end cover, the cavity is filled with rubber, and the rubber is arranged in the cavity. Forming an upper supporting block and a lower supporting block so as to wrap the end part of the plate spring extending into the cavity; a hollow direction is reserved in the cavity and located at the extending end of the plate spring in the horizontal direction. According to the structure, the scheme of a metal pin shaft or a plate spring bushing is innovatively omitted, on the basis that the plate spring system is effectively connected and supported, a spring eye structure does not need to be designed at the end of the plate spring system, machining is easier and more convenient, and forming is easy; the inner rubber blocks of the plate spring end supports are connected with the two ends of the plate spring; more axial movement space can be released for the plate spring, so that the comfort of the whole vehicle is greatly improved; and the assembly mode is simpler and more convenient.
本发明涉及一种重卡板簧系统技术领域,具体涉及板簧用橡胶支承结构,包括板簧和板簧端部支承,所述板簧包括板簧端部和板簧中部,所述板簧端部支承为设置在板簧端部,包括上端盖和下端盖围合的腔体,所述腔体内填充有橡胶,形成上、下支承块,以包裹伸入腔体内部的板簧端部;所述腔体内部留设有空向,空向位于板簧水平方向的延伸端。该结构创新性地取消了金属销轴或者板簧衬套方案,在有效连接支承板簧系统基础上,板簧系统端部无需设计卷耳结构,其加工更加简便,且易于成型;通过板簧端部支承内部橡胶块与板簧两端连接;可给板簧释放更多的轴向运动空间,使整车舒适性大大地提高;装配方式更为简便。
