Vehicle steering device with switchable front and rear wheel drive on the deck of a ro-ro ship

Abstract

The invention relates to a board car steering device capable of switching the driving of front wheels and rear wheels of a roll-on roll-off ship deck, which solves the problem that a large parking space on a deck is occupied by a turning position and a turning-round position of a car. A turning plate which is installed on the deck in a rotating manner is arranged on the end of a traveling passageway or on the intersection position of the traveling passageway of a side edge of the deck, a plurality of groups of rollers for carrying car wheels are uniformly arranged on the turning plate along the circumferential direction, each group of rollers comprises an inner roller and an outer roller, a worm which is parallel to the roller is respectively arranged below each roller, each outer roller is connected to one end of the worm through a clutch in a forwarding transmission manner, each inner roller is connected to the other end of the worm through the clutch in a reversed transmission manner, the outer side of the worm is correspondently provided with a worm gear, the bottom of the worm gear is connected with a rotating gear through a ratchet wheel, an inner gear ring which is engaged with the rotating gear is fixedly arranged on the deck, and the inner gear ring is coaxially arranged with the rotating plate. The car can be pivot steered by utilizing the power of the car, the space needed for the steering of the car on the deck is reduced, and the exchangeability of the front wheel-driven and the rear wheel-driven car steering can be realized.

Description

technical field [0001] The invention relates to ship deck auxiliary facilities, in particular to an automobile steering device with switchable front and rear wheel drives on the deck of a roll-on ship. Background technique [0002] The sea transportation of large quantities of automobiles is generally carried out by ro-ro ships. For ro-ro ships, the total cost of a single transportation is relatively large, and the cost of a single transportation is basically stable and basically not affected by the transportation volume. Therefore, in Carrying as many goods as possible can reduce the average transportation cost per unit of goods when the load capacity allows. When transporting cars on the deck of a ro-ro ship, it is necessary to plan the driving route for the car to ensure that the car can drive to various positions on the deck smoothly. Correspondingly, there needs to be enough open space where the car needs to turn or turn around on the side of the deck , for vehicles to...

Problems solved by technology

When transporting cars on the deck of a ro-ro ship, it is necessary to plan the driving route for the car to ensure that the car can drive to various positions on the deck smoothly. Correspondingly, there needs to be enough open space where the car needs to turn or turn around on the side of the deck , for vehicles to turn or turn around. In order to ensure driving safety, these reserved spaces usually occupy a relatively large space, which invisibly occupies the space for parking cars on the deck.
