The invention discloses a detachable auxiliary frame of an electric automobile. The detachable auxiliary frame comprises a suspension, a first cross beam and a pair of side beams arranged in a bilateral symmetry mode. The first cross beam connects the pair of side beams with each other, is close to the front ends of the side beams and is perpendicular to the side beams; the suspension is used forbearing a power assembly and arranged at the rear end of the side beam, and the two ends of the suspension are fixedly connected to the inner sides of the side beams. The front sections of the side beams are fixedly connected with a vehicle body longitudinal beam, and the rear sections of the side beams are fixedly connected with a vehicle body threshold connecting plate; a second cross beam is arranged at the front end of each side beam and is parallel to the first cross beam, and an anti-collision energy absorption device used for crumple energy absorption is arranged between the second cross beam and the side beam. Compared with the prior art, the auxiliary frame has the advantages that the problem of contradiction between the collision space and the design requirement of the short front overhang during vehicle collision is solved, and the auxiliary frame is beneficial to arrangement of a power assembly, so that the manufacturing cost is reduced, and the collision safety performanceof the vehicle can be remarkably improved.
本发明公开了一种可脱落式电动汽车副车架,包括悬架、第一横梁和一对左右对称设置的侧梁;第一横梁将一对侧梁彼此连接,第一横梁靠近侧梁的前端,并垂直于侧梁;悬架用于承载动力总成,悬架设于侧梁的后端,悬架的两端固定连接于侧梁的内侧;侧梁的前段与车身纵梁固定连接,侧梁的后段与车身门槛连接板固定连接;侧梁的前端设有第二横梁,第二横梁与第一横梁平行,第二横梁与侧梁之间设有用于溃缩吸能的防撞吸能装置。本发明相对于现有技术,解决了在车辆碰撞时碰撞空间与短前悬的设计要求存在矛盾的问题,该副车架有利于动力总成的布置,从而降低了制造成本,而且能够显著提高车辆的碰撞安全性能。
