Abstract

The utility model relates to a water motive power transmission device for an amphibious automobile, characterized in that a power input shaft of a transfer case driven front wheels of the automobile is directly connected with a gear box fixed to the tail of the automobile through a gear sleeve clutch and a transmission shaft; the gear box translates the power of the engine of the automobile to the required height of the high-speed propeller without slowing down. The utility model which needs no additional reduction mechanism has the advantages of simple structure and convenient operation, and effectively improves the vehicle performance under the amphibious transport conditions and the identity of the operation and driving; therefore, the water accessing condition of the vehicles is improved.

Description

Water motive power transmission device for amphibious automobile

The utility model relates to a kind of marine propulsion power drive that common cross country car is repacked into amphibious automobile.

In the prior art, with the amphibious automobile of common cross-country car repacking, the middle slow spin that all uses customized design to make is starched as swimmer propulsion unit.This propeller diameter big (more than 500 millimeters), working speed low (per minute is no more than 800 to be changeed) for the takeoff output with main-gear box matches, needs increase marine propulsion system's power-transfer clutch and reducing gearbox main-gear box after.Like this, not only reduced the operation homogeneity of vehicle under different motoring conditions, increased the complexity of driver's operation, but also have a strong impact on the discrepancy water-based energy of vehicle and the speed of in water, travelling, and the land locomotion performance of former car such as maximum speed per hour, maximum climbing, consumption of fuel etc. have been worsened.

The purpose of this utility model is to overcome above-mentioned defective, a kind of marine propulsion system slowdown mechanism that need not set up on former car basis is provided, can improve the performance of vehicle two kinds of different motoring conditions and the homogeneity that operation is driven, and help improving the amphicar marine propulsion power drive of vehicle discrepancy aqueous condition in land and water.

The technical solution of the utility model is: the power input shaft that vehicle front is driven auxiliary gear box directly links with the gear case that is fixed on the vehicle afterbody by tooth cover power-transfer clutch and transmission shaft, this gear case is equipped with a pair of or two pairs of engaging gears that the number of teeth is identical, the car engine mechanomotive force is not moved to with not slowing down the height of propshaft design, and the anticlockwise of automotive engine takeoff output is changed over right rotation by gear mesh, thereby can adopt common high-speed screw peculiar to vessel slurry, to improve the performance of vehicle under the two kinds of different motoring conditions in land and water.

Fig. 1 is the structural representation of the utility model embodiment 1;

Fig. 2 is the structural representation of the utility model embodiment 2.

Gear case 2 is fixed on the afterbody of vehicle.The one end usefulness universal-joint of transmission shaft 1 connects with the imput shaft 3 in the gear case 2, its other end connects with the power input shaft that vehicle front drives auxiliary gear box by tooth cover power-transfer clutch, just the engine power that reaches propeller can be switched on or switched off by the original control steering unit of automobile.High-speed screw slurry 7(maximum functional rotating speed is more than 500 rev/mins) be contained on the slurry axle 8, power is by reciprocity tooth cylindrical wheel 4,5 inputs.For improving lubricating condition, slurry axle 8 adopts oil-lubricated bearing, because gear housing 2 is parts of whole sealing car body 6, the slurry axle 8 that need only expose adopts oil sealing 9 with the intersection of gear case, just can prevent that sealing enters in the sealing car body and the wet goods material enters contaminated environment in the water, thereby significantly reduce the water-stop work capacity and improved sealing property.In order to prevent to produce eddy current near the propeller, the utility model also is provided with fairing 10.

For different vehicles, car body overhead distance height differs, for the slurry axle 8 that satisfies different automobile types can reach best design height, can set up tween drive spindle 11 between imput shaft 3 and the slurry axle 8, tween drive spindle 11 and imput shaft 3, slurry axle 8 is perpendicular, and power drives propeller 7 by two pairs of identical bevel gears of the number of teeth.The length of second(-)motion shaft 11 has determined the design height of slurry axle 8.

The utility model compared with prior art has the following advantages:

1,, and do not need speed reduction gearing owing to adopt high-speed screw slurry in light weight, minor diameter, thus simple in structure, weightening finish is few, to the land rideability of former car adverse effect significantly not.Moreover high-speed screw slurry specification is many, interchangeability good, has easily bought in market, can select the propeller of different size according to the different task and the working environment of vehicle.

2, identical with the designed draft degree of depth in the prior art middle slow spin slurry is compared, and high-speed screw slurry terrain clearance is bigger.High and departure angle etc. all can keep the performance figure of former car to amphibious vehicle after the repacking in the crack, ground, and when the identical ground Clearance, high-speed screw is starched the slurry used than prior art, absorb water darker, rotating speed is faster, improves the performance that vehicle travels on the water greatly.

3, consistent because of the working speed of propeller with the working speed scope of automotive engine, thus the marine propulsion driving system that increases to the performance of the land driving transmission agent of former car and function without any restriction with disturb.No matter be that the land transmission system of former car is in any mode of operation, static as four wheel drive, two-wheel drive, four-wheel, the marine propulsion driving system is overlapped power-transfer clutch by a simple tooth, can with the land transmission system or work together or work independently or two systems separate of travelling of former car.When the connection of two systems was worked together, the marine propulsion driving transmission agent can be handled with driving engine master clutch and main-gear box equally.Therefore, amphibious vehicle after the repacking not only has good operation homogeneity at water, the two kinds of motoring conditions in land, and also simplify greatly in the complexity of the conversion (going out entry) of two kinds of motoring conditions operation, make the entry that of vehicle drive as land uphill/downhill operation of travelling simple and convenient.

4, because the slurry axle has adopted oil-lubricated bearing, use water lubricated bearing often to burn out the phenomenon of slurry axle in the prior art thereby overcome, like this, the entry that goes out of vehicle can continually under the situation of not switching the marine propulsion driving system be finished continuously.Vehicle can connect bank with the speed waterborne of maximum, go ashore and climb by bigger inertia, and propulsion system can not burn out the slurry axle on the continuous boiling water of long distance travel after the water outlet yet, improved greatly vehicle the discrepancy water-based can and the operation quality.

5, tailstock gear case is as the part of sealing car body 6, have only an end of slurry axle 8 to be exposed in the water,, help the sealing of car body like this by the water-stop parts of oil sealing as propulsion system and sealing car body, reduce the work capacity of water-stop, thereby reduced manufacturing cost.
