The invention provides an automobile front suspension framework, belongs to the technical field of automobiles and aims to solve the problems that an existing automobile engine is poor in falling accuracy during collision, inconvenient to maintain in the later period and higher in cost. According to the automobile front suspension framework, two automobile body longitudinal beams which are arranged at intervals are arranged in an engine compartment of an automobile. The front suspension framework comprises an auxiliary frame and a power assembly; the power assembly is connected with the auxiliary frame only through a plurality of suspension structures arranged in the circumferential direction of the power assembly at intervals and is located between the two automobile body longitudinal beams; the auxiliary frame is connected with the two automobile body longitudinal beams only through connecting bolts sequentially penetrating through the auxiliary frame and the automobile body longitudinal beams; the material strength of the auxiliary frame and the material strength of the automobile body longitudinal beams are larger than that of the connecting bolts; and the connecting bolts canbe broken when the auxiliary frame generates longitudinal displacement relative to the automobile body longitudinal beams. When the automobile is subject to collision, an engine and the auxiliary frame sink and fall off, invasion of the engine and the auxiliary frame into a cab is avoided, the accuracy of the breakage of the connecting bolts is higher, and unnecessary breakage is avoided.

    本发明提供了一种汽车前悬架构,属于汽车技术领域。它解决了现有的汽车发动机在碰撞时脱落准确性较差且后期维护不便成本更高的问题。本汽车前悬架构,汽车的发动机舱内具有两条间隔设置的车身纵梁,本前悬架构包括副车架和动力总成,所述动力总成仅通过若干沿动力总成周向间隔设置的悬置结构与副车架连接并位于两个车身纵梁之间,所述副车架仅通过依次穿过副车架和车身纵梁的连接螺栓与两个车身纵梁连接,所述副车架以及车身纵梁的材料强度大于连接螺栓的材料强度,且连接螺栓能够在副车架相对车身纵梁产生纵向位移时断裂。本发明能够在汽车碰撞时,使发动机与副车架下沉脱落,避免侵入驾驶室,且连接螺栓断裂的精确性更高,避免非必要断裂。
