The invention discloses a sanitation vehicle upper part and chassis connecting device, and belongs to the technical field of sanitation special vehicles. Comprising a chassis and an upper assembly, and further comprises a first elastic connecting assembly, a second elastic connecting assembly and a rigid connecting assembly which are used for connecting the chassis and the upper assembly, the first elastic connecting assembly comprises an upper elastic support, a lower elastic support, a lengthened bolt, a spring and a locking nut, the upper elastic support is fixedly connected with an upper assembly longitudinal beam of the upper assembly, and the lower elastic support is fixedly connected with a lower assembly longitudinal beam of the upper assembly. The lower elastic supports are arranged below the upper elastic supports at intervals and fixedly connected with a chassis longitudinal beam, the lengthened bolts sequentially penetrate through the upper elastic supports and the lower elastic supports from the upper portions of the upper elastic supports, the springs are arranged on the upper sections of the lengthened bolts in a sleeving mode, the bottom ends of the springs abut against the upper elastic supports, and the lower elastic supports are fixedly connected with the chassis longitudinal beam. And the locking nut is screwed at the lower end of the lengthened bolt. The vehicle frame has the advantages that impact of road surface vibration on the upper part and the chassis is effectively reduced, and the service life of the vehicle frame is prolonged; reliable connection of the sanitation vehicle upper part and the chassis can be achieved.
