The invention discloses a steering connection structure. The steering connection structure comprises an underframe cross beam and a steering wheel carrier, an upper hinge seat and a lower hinge seat are arranged at the end part of the chassis cross beam, the steering wheel frame is provided with an upper steering mounting seat and a lower steering mounting seat corresponding to the upper hinge seat and the lower hinge seat, the upper hinge seat is hinged with the upper steering mounting seat, and the lower hinge seat is hinged with the lower steering mounting seat; the upper hinge seat and the lower hinge seat are pressed on the upper steering mounting seat and the lower steering mounting seat respectively after being assembled, so that the upper steering mounting seat and the lower steering mounting seat support the upper hinge seat and the lower hinge seat respectively, and four-point support of the steering wheel carrier to the underframe cross beam is realized. The invention further provides a chassis assembly. According to the steering connection structure and the chassis assembly thereof, the design scheme of the chassis cross beam and the steering wheel carrier mechanism which are integrally loaded, dispersed in stress and small in deformation is provided, and the stress concentration and the deformation of the ends of the chassis cross beam can be remarkably reduced.
