The invention discloses an automobile auxiliary frame, an automobile auxiliary frame system and an automobile. The automobile auxiliary frame comprises an auxiliary frame body and a plurality of connecting assemblies. Wherein each connecting assembly comprises a first connecting piece and a second connecting piece, the first connecting piece is in sliding connection with the second connecting piece, the end, away from the second connecting piece, of the first connecting piece is fixedly connected with the auxiliary frame body, and the end, away from the first connecting piece, of the second connecting piece is fixedly connected with a vehicle body. Each first connecting piece can slide relative to the corresponding second connecting piece according to the vibration condition of the auxiliary frame body, the adjustable range of the connecting assembly relative to the rubber bushing is larger, and therefore it can be guaranteed that the vibration isolation performance of the auxiliary frame is kept at a high level all the time, vibration transmission from the auxiliary frame to a vehicle body can be effectively attenuated, and the service life of the auxiliary frame is prolonged. Therefore, the risk of noise or large vibration caused by vehicle body vibration is reduced, and the driving comfort is improved.

本发明公开了一种汽车副车架、汽车副车架系统及汽车，汽车副车架包括副车架本体和多个连接组件；其中，每个连接组件包括第一连接件和第二连接件，第一连接件与第二连接件滑动连接，第一连接件的远离第二连接件的一端与副车架本体固定连接，第二连接件的远离第一连接件的一端与车身固定连接。各第一连接件能够根据副车架本体的振动情况相对于对应的第二连接件滑动，该连接组件相对于橡胶衬套的可调范围更大，从而能够保证副车架的隔振性能一直保持在较高的水平，可以有效衰减副车架到车身的振动传递，从而降低车身振动引发噪声或振动大的风险，提升驾乘舒适性。
