CN201895543U - Water-running propeller for all-terrain vehicle - Google Patents

Abstract

The utility model discloses a water-running propeller for an all-terrain vehicle and relates to the field of an all-terrain transport vehicle; a vehicle body of the all-terrain vehicle is designed to be internally provided with water channels; a screw propeller is utilized to suck water from water inlets of the water channels and to spray the water from the water outlets so as to propel the all-terrain vehicle to run on the water; and the turning and the backing-up of the all-terrain vehicle in the water can be controlled through opening and closing end covers of water channel ports. The propeller solves the problem that the all-terrain vehicle broaches and can not go ashore; as the propeller adopts hydraulic transmission, the speed adjustment can be realized through changing the displacement; the speed change is stable; the vehicle can run at arbitrary speed within a permitted scope; and the screw propeller can be better matched with an engine, so as to achieve optimal tractive characteristic.

Description

Propelling unit travels in the all-terrain vehicle water

Technical field

The novel running gear of all-terrain vehicle is mainly used in full landform transport trolley.

Background technology

Full landform transport trolley, maximum characteristics are to be difficult to walk freely on the power operated landform in common vehicle.Can travel comprising on all landform such as desert, snowfield, marsh, highway and landlocked rivers, lake, water route, be mainly used in and carry goods and materials, equipment, ammunition, oil plant, combatant etc.The military potentiality of all-terrain vehicle are familiar with by the army of more and more national, and it can be equipped on Amphibious mechanical army and marine corps.All-terrain vehicle is waterborne to rely on when travelling crawler belt to strike, and efficient is low, and speed is 4-6km/h only, and manoevreability is relatively poor.If one crawler belt touches the bottom, shoal, can make all-terrain vehicle in water, turn to get out of hand suddenly.A crawler belt touches bank earlier during water outlet, may cause vehicle to take the least important seat at a square table and can not debark, after need returning again to water outlet after the positive dirction.

The utility model content

The utility model purpose is to overcome above-mentioned deficiency, by a cover water channel and a screw propeller respectively arranged about the all-terrain vehicle car body, the water inlet of water channel is in the car front portion, water outlet is at the tailstock, respectively go out, water inlet all has a lid, two screw propellers are installed in the water channel jet pipe, advance by screw propeller water spray, the speed of a motor vehicle can be increased to 10km/h (actual vehicle speed is by environment decision in the water at that time) when all-terrain vehicle is travelled in hydrostatic.Each water channel all has a reverse spout, can realize freely turning to and moveing backward by the open and close by each water outlet lid when travelling, and has both increased manoevreability and crossing ability in the water of all-terrain vehicle, has also solved the problem that all-terrain vehicle is taken the least important seat at a square table and can not be debarked.

The utility model is because this propelling unit has adopted hydrostatic drive, be easy to install, easy to maintenance, avoided mechanical drive to be delivered to the back car and be not easy to the big problem of installing, take up room from front truck, and hydraulic transmission can realize speed governing by changing discharge capacity, speed change is steady, can vehicle be travelled with arbitrary speed, to reach best tractive characteristic.

The specific embodiment

As shown in Figure 1, propelling unit is installed in the all-terrain vehicle, 1 is each water outlet end cap, and 2 is car body, and 3 is screw propeller.The water channel water inlet is in the car front portion; water outlet is at the tailstock; to a reverse water injector be installed respectively on the water outlet of both sides simultaneously; two screw propellers are installed in the water channel jet pipe, have promptly formed so-called waterjet propulsion, simultaneously; blade be protected just can not touch in the water and the road on obstacle; respectively go out, water inlet all has a lid, closes each mouth of a river lid when travelling on land, enters water channel to prevent foreign material.Car body is left and right as shown in Figure 2 respectively has one to overlap water channel and screw propeller.As shown in Figure 3, each water channel all has a reverse spout, closes a sidecar tail water outlet end cap all-terrain vehicle is turned in water flexibly, closes two end caps of hull back and can be implemented in reverse travel in the water.For example: the afterbody water outlet is all opened when both sides, and closes the reverse water outlet in both sides, and all-terrain vehicle will be to overtake; When the sealing of left side water outlet, open oppositely water outlet of left side, simultaneously the right side water outlet is opened, close the reverse water outlet in right side, car body will turn to left.Right-hand turning is to also using identical principle; The afterbody water outlet is all closed when both sides, when the reverse spout in both sides is all opened, can realize the all-terrain vehicle reverse travel.

As shown in Figure 4, native system is made up of unidirectional controllable capacity pump, two position and four-way reversing valves, by pass valve, flow divider valve, oil filter and two fixed displacement motors.Driving engine drives unidirectional controllable capacity pump, and when change-over valve was in position, a left side, hydraulic oil was through the direct oil sump tank of change-over valve, and at this moment system does not work.When change-over valve was in right position, oil was flowed through through change-over valve and is entered two motors behind the flow divider valve and drive revolution, and at this time screw propeller is started working.The oil filter of carry magnet and a micronic filter are protected pump and Hydraulic Elements respectively.Flow divider valve play make flow through about two motor flows equate, thereby guaranteed two motor rotary speed unanimities, avoided because two motor rotary speeds are inconsistent two different phenomenons that make running out the way of water channel injection flow rate about causing.Can realize the change of motor rotary speed by regulating capacity of pump, thereby reduce or improve fltting speed.

The above is exactly preferred embodiment of the present utility model, and every foundation technical spirit of the present utility model all still belongs in the technical solution of the utility model scope any simple modification, equivalent variations and modification that above embodiment did.

Claims (2)

1. propelling unit in the all-terrain vehicle water, be installed on the all-terrain vehicle, described all-terrain vehicle respectively has a cover water channel and a screw propeller about car body, the water inlet of water channel is in the car front portion, water outlet is at the tailstock, respectively go out, water inlet all has a lid, it is characterized in that: two screw propellers are installed in the water channel jet pipe.
