The elastic connection equipment which is used in the air cushion mixed vehicle belongs to the mechanical engineering carrying tool technical field. It consists of the spring supporting seat, the spring. The characteristic of the invention also contains the screw, the slideway, the pulley, the slip block, the superior holding board, the aniseed loop, the inferior holding board and the inferior connected part. It rigidly connects between the screw and the superior holding board. The top and bottom of the aniseed loop separately connects the superior holding board and the inferior holding board which is fixed on the inferior connected part. The spring is placed between the spring supporting seat which connects with the slideway and the superior holding board. The pulley connects with the slip block. The invention achieves the altitudinal accommodation of the vehicle body relative sashaying equipment and the load transferring between the vehicle body and the sashaying equipment. At the same time, it also can achieve the load matching and the power matching. Therefore, it avoids too many the power consuming.
