本发明属于轴承技术领域，具体涉及一种减震器轴承。
背景技术
汽车减震器是车轮与车体之间的弹性连接传力部件，主要作用是抑制弹簧吸震后反弹时的震荡及来自路面的冲击，加速车架与车身振动的衰减从而改善汽车的行驶舒适性，汽车减震器包括减震器轴承，减震器轴承的性能直接影响汽车减震器的性能，影响驾驶者的驾驶体验及乘客的乘车体验，为了提高汽车整体的性能，提高市场竞争力，汽车相关厂商都在对汽车整体和相关零部件做相应的优化和改进，现有的减震器轴承已无法满足汽车性能提升需求。
减震器轴承的优化方向包括对减震器轴承进行轻量化设计、提高轴承密封性、提高减震器轴承与减震器其他部件的配合、提高安装效率等。
发明内容
为了克服现有技术的不足，本发明提供了一种比现有的减震器轴承更能满足汽车性能提升需求的减震器轴承。
为了实现上述目的，本发明采用的技术方案是：一种减震器轴承，包括环形的上盖和环形的下盖，所述上盖朝向下盖的面上设有上沟道圈，所述下盖朝向上盖的面上设有下沟道圈，所述上沟道圈和下沟道圈之间设有滚动体，所述上盖背向下盖的面上设有环形凹腔，所述环形凹腔的轴线与上盖的轴线重合，所述环形凹腔内设有多个沿上盖的轴向延伸的隔板，所述上盖还设有减重腔，所述减重腔由环形凹腔经隔板分割而成的多个小凹腔构成。
采用上述方案，通过在上盖设置减重腔，可有效减少上盖的重量，使本发明相较于现有的减震器轴承更加轻量化，隔板起支撑作用，在上盖重量减少的同时，保证上盖的强度满足实际使用需求。
作为本发明的进一步设置，所述环形凹腔为圆环形凹腔，所述隔板包括多个沿环形凹腔的周向均匀分布的径向隔板和设置在相邻两个径向隔板之间的斜向隔 板，相邻所述斜向隔板之间首尾相接，所述斜向隔板连接相邻两个径向隔板不同端，所述径向隔板两侧的斜向隔板沿该径向隔板镜像对称。
作为本发明的进一步设置，所述环形凹腔为正多边形凹腔，所述隔板包括多个沿多边形棱线分布的径向隔板和设置在相邻两个径向隔板之间的斜向隔板，相邻所述斜向隔板之间首尾相接，所述斜向隔板连接相邻两个径向隔板不同端，所述径向隔板两侧的斜向隔板沿该径向隔板镜像对称。
采用上述方案，环形凹腔为圆环形凹腔时，减重腔沿上盖径向的截面近似三角形，环形凹腔为正多边形凹腔时，减重腔沿上盖径向的截面为三角形，该设置能提供更好的支撑效果。
相较于圆形或近似圆形的减重腔，本发明相邻减重腔之间的隔板的厚度一致或变化小，隔板受到的压力更加平均，而且本发明隔板的整体厚度小于圆形或近似圆形的减重腔之间的隔板厚度，近似三角形或三角形的减重腔在保证强度的同时，轻量化效果更好，
相较于方形、扇形或近似方形的减重腔，近似三角形或三角形的减重腔能更好的保持减重腔形状的稳定，受到轴向载荷时上盖不易产生形变。
作为本发明的进一步设置，所述环形凹腔靠近上盖外壁的腔壁与上盖外壁之间的厚度一致，所述环形凹腔靠近上盖内壁的腔壁与上盖内壁之间的厚度一致。
采用上述方案，环形凹腔的外腔壁与上盖外壁之间的厚度一致，环形凹腔的内腔壁与上盖内壁之间的厚度一致，有助于平衡上盖受到的压力，防止因厚度不一致使得上盖各部位压力不平衡，而导致上盖整体强度下降，防止上盖在使用过程中出现形变而影响本发明的正常使用。
作为本发明的进一步设置，相邻所述斜向挡板之间的夹角为钝角。
采用上述方案，在保证隔板支撑力的同时，能有效减少环形凹腔内隔板的数量，保证环形凹腔的减重效果。
作为本发明的进一步设置，所述滚动体为球体，所述环形凹腔的腔底与经过所有滚动体圆心的平面相平行。
上盖背向下盖的面与经过所有滚动体圆心的平面之间可能存在夹角，采用上述方案，可在保证上盖强度的同时，增大减重腔的体积，防止因环形凹腔腔底至 所有滚动体的圆心所在平面的距离不一致，而导致实际使用时距离较近处出现形变。
作为本发明的进一步设置，所述上盖的内壁上设有多条加强筋，所述加强筋沿上盖内壁的周向排列，所述上盖内壁远离下盖的一侧设有向外延展的弧形的延展面，所述加强筋包括延伸至延展面的延伸段，所述延伸段由靠近下盖的一端至远离下盖的一端突出内壁的高度逐渐降低。
采用上述方案，加强筋能有效降低上盖与穿设在上盖内的轴的接触面积，在进一步减少上盖整体重量的同时，保证上盖的强度，延伸段的形状使得加强筋整体不容易在装配和受到轴向载荷时出现形变或断裂，保证加强筋的完整性，保证加强筋的作用。
作为本发明的进一步设置，所述上盖远离下盖的面整体由外沿至内沿向远离下盖的方向拱起。
采用上述方案，上盖远离下盖的面为曲面，能更好的外部连接件配合。
作为本发明的进一步设置，所述上盖的轴线和下盖的轴线之间存在夹角，所述夹角的角度小于10°。
作为本发明的进一步设置，所述下盖采用工程塑料制成，所述下盖采用金属制成。
采用上述方案，现有的减震器轴承的上盖和下盖的材质一致，通常为全金属或全塑料制成，金属及塑料各有其优缺点，金属材质相较于塑料材质，有耐热性好、耐久性好、尺寸稳定等特点，但重量较重、不易加工成型，塑料材质相较于金属材质，有质量轻、易于成型、耐冲击、化学性能稳定等特点，但稳定性不如金属，而且改性塑料的成本高，根据上盖和下盖受到的载荷以及作用不同，本发明的上盖和下盖采用不同材质制成，能更好的发挥不同材质的优点，提高本发明的整体性能。
作为本发明的进一步设置，所述上盖通过3D打印将工程塑料制成的打印丝进行多次叠加融合而成。
采用上述方案，现有的塑料材质的上盖多采用注塑而成，本发明若通过注塑制造，容易出现脱模不良、注塑不完整等问题，特别是减重腔部分，若采用注塑 制造，可能会出现隔板缺失、隔板壁厚不均匀等问题，严重影响上盖整体强度，3D打印能很好的控制成品形状，精度高。

相较于方形、扇形或近似方形的减重腔121，近似三角形的减重腔121能更好的保持减重腔121形状的稳定，受到轴向载荷时上盖1不易产生形变。
环形凹腔12靠近上盖1外壁的腔壁与上盖1外壁之间的厚度一致，环形凹腔12靠近上盖1内壁的腔壁与上盖1内壁之间的厚度一致。有助于平衡上盖1受到的压力，防止因厚度不一致使得上盖1各部位压力不平衡，而导致上盖1整体强度下降，防止上盖1在使用过程中出现形变而影响本发明的正常使用。
相邻斜向挡板之间的夹角a为钝角。在保证隔板13支撑力的同时，能有效减少环形凹腔12内隔板13的数量，保证环形凹腔12的减重效果。夹角a包括背向上盖1轴线的夹角a1和朝向上盖1轴线的夹角a2，本实施例中，110°＜a1＜a2。
环形凹腔12的腔口至腔底的深度一致，方便加工。
上盖1远离下盖2的面为平面。
上盖1的轴线和下盖2的轴线之间存在夹角b，夹角b的角度小于10°,本实施例中，夹角b为7.5°。
下盖2采用工程塑料制成，下盖2采用金属制成。现有的减震器轴承的上盖和下盖的材质一致，通常为全金属或全塑料制成，金属及塑料各有其优缺点，金属材质相较于塑料材质，有耐热性好、耐久性好、尺寸稳定等特点，但重量较重、不易加工成型，塑料材质相较于金属材质，有质量轻、易于成型、耐冲击、化学性能稳定等特点，但稳定性不如金属，而且改性塑料的成本高，根据上盖1和下盖2受到的载荷以及作用不同，本发明的上盖1和下盖2采用不同材质制成，能更好的发挥不同材质的优点，提高本发明的整体性能。
上盖1通过3D打印将工程塑料制成的打印丝进行多次叠加融合而成。现有的塑料材质的上盖1多采用注塑而成，本发明若通过注塑制造，容易出现脱模不良、注塑不完整等问题，特别是减重腔121部分，若采用注塑制造，可能会出现隔板13缺失、隔板13壁厚不均匀等问题，严重影响上盖1整体强度，3D打印能很好的控制成品形状，精度高。
实施例二：实施例二与实施例一大致相同，实施例二与实施例一的不同之处如附图5所示，实施例二中，环形凹腔12为正多边形凹腔，隔板13包括多个沿多边形棱线分布的径向隔板131和设置在相邻两个径向隔板131之间的斜向隔板132，相邻斜向隔板132之间首尾相接，斜向隔板132连接相邻两个径向隔板131不同端，径向隔板131两侧的斜向隔板132沿该径向隔板131镜像对称，减重腔121沿上盖1径向的截面为三角形。环形凹腔12为正多边形凹腔的效果与环形凹腔12为圆环形凹腔的效果类似，该设置能提供很好的支撑效果。
环形凹腔12靠近上盖1外壁的腔壁与上盖1外壁之间的厚度存在差异，环形凹腔12靠近上盖1内壁的腔壁与上盖1内壁之间的厚度存在差异。
实施例三：实施例三与实施例一大致相同，实施例三与实施例一的不同之处如附图6所示，上盖1背向下盖2的面与经过所有滚动体3圆心的平面之间存在夹角。环形凹腔12的腔底与经过所有滚动体3圆心的平面相平行，可在保证上盖 1强度的同时，增大减重腔121的体积，防止因环形凹腔12腔底至所有滚动体3的圆心所在平面的距离不一致，而导致实际使用时距离较近处出现形变。
实施例四：实施例四与实施例三大致相同，实施例四与实施例三的不同之处如附图7～8所示，上盖1的内壁上设有多条加强筋14，加强筋14沿上盖1内壁的周向排列，上盖1内壁远离下盖2的一侧设有向外延展的弧形的延展面15，加强筋14包括延伸至延展面15的延伸段141，延伸段141由靠近下盖2的一端至远离下盖2的一端突出内壁的高度逐渐降低。加强筋14能有效降低上盖1与穿设在上盖1内的轴的接触面积，在进一步减少上盖1整体重量的同时，保证上盖1的强度，延伸段141的形状使得加强筋14整体不容易在装配和受到轴向载荷时出现形变或断裂，保证加强筋14的完整性，保证加强筋14的作用。
实施例五：实施例五与实施例四大致相同，实施例五与实施例四的不同之处如附图9所示，上盖1远离下盖2的面整体由外沿至内沿向远离下盖2的方向拱起。上盖1远离下盖2的面为曲面16，能更好的外部连接件配合。
实施例六：实施例六与实施例一大致相同，实施例六与实施例一的不同之处如附图10所示，实施例六中相邻斜向挡板之间的夹角a’小于实施例一种相邻斜向挡板之间的夹角a，夹角a’包括背向上盖1轴线的夹角a’1和朝向上盖1轴线的夹角a’2，本实施例中，70°＜a’1＜a’2≤90°。
本发明不局限于上述具体实施方式，本领域一般技术人员根据本发明公开的内容，可以采用其他多种具体实施方式实施本发明的，或者凡是采用本发明的设计结构和思路，做简单变化或更改的，都落入本发明的保护范围。
