The invention relates to the technical field of engineering machinery, and discloses a chassis assembly and engineering machinery. The chassis assembly comprises a chassis (10) and a rear supporting leg (20) hinged to a rear hinge point of the chassis, the rear supporting leg (20) can rotate between a first folded position and a first unfolded position relative to the chassis (10), and the rear supporting leg (20) can rotate between a second folded position and a third unfolded position relative to the chassis (10). The rear leg (20) extends forward from the rear hinge point at a side of the chassis (10). The rear supporting legs arranged at the rear hinge points of the chassis can be folded at the side edges of the chassis when being at the folding positions, so that on one hand, the longer rear supporting legs can be provided, the problem that the length of a vehicle body is too long due to the fact that the length of the rear supporting legs is increased can be solved, on the other hand, weight distribution is balanced, and the problem that a rear axle of the vehicle is too heavy can be effectively solved.

    本发明涉及工程机械技术领域,公开了一种底架组件以及工程机械,所述底架组件包括底架(10)以及铰接于所述底架的后铰点的后支腿(20),所述后支腿(20)能够相对于所述底架(10)在第一收起位置和第一展开位置之间转动,在所述收起位置,所述后支腿(20)在所述底架(10)的侧部从所述后铰点向前延伸。设置于所述底架后铰点的后支腿能够在收起位置时,收起于所述底架的侧边,这样一方面能够具有更长的后支腿并且能够避免由于后支腿长度增加导致的车身长度超长的问题,另一方面重量分布均衡,能够有效避免车后桥超重的问题。
