The general vehicle frame of amphibious AWD all-terrain vehicleTechnical field
Patent of the present invention is the general vehicle frame of a kind of amphibious AWD all-terrain vehicle, specifically the general vehicle frame of a kind of four-wheel microlight-type amphibious AWD all-terrain vehicle.
Background technology
Domestic and international all terrain vehicle is when passing through high mountain, valley, desert, rainforest area now, run into ground difference of height apart from too large and soft road conditions, still have the technology barrier being difficult to go beyond, there will be tyre slip, wheel hanging stall, greatly reduce the crossing ability of vehicle, and as run into the water surface, wetland and marsh, crossing ability is not known where to begin especially.
Summary of the invention
Patent of the present invention technical matters to be solved is the general vehicle frame of one amphibious AWD all-terrain vehicle microlight-type of the theory design designing aircraft, the suspension of each tire is multi-connecting-rod separated suspension, and each drive wheel is driven by forward and backward transmission shaft and semiaxis.By changing the dissimilar tire with interchangeability, when all-terrain vehicle can not only be made to run, all wheels regulate height to adapt to various rugged severe road conditions automatically, and, the buoyancy utilizing huge tire to produce, make amphibious AWD all-terrain vehicle the water surface and palustrine also as though walking upon flat ground.
Patent of the present invention technical matters to be solved realizes with following technical proposal:
The amphibious AWD all-terrain vehicle of a kind of four-wheel, core main body is the general vehicle frame of microlight-type AWD of the theory design designing aircraft, at universal vehicle frame, former and later two drive axles are set, drive wheel is equipped with at drive axle two ends, by changing different tires to adapt to various rugged severe road conditions, and, the buoyancy utilizing huge tire to produce, make amphibious all-terrain vehicle the water surface and palustrine also as though walking upon flat ground.
Described amphibious AWD all-terrain vehicle takes the integral structure of the type of drive of unique mid-AWD of longitudinal direction, to solve center of gravity and the load-carrying problem of amphibious AWD all-terrain vehicle in the environment in the water surface and marsh.
The power of amphibious AWD all-terrain vehicle is divided into front propeller shaft and rear propeller shaft by control clutch and change speed gear box in center differential part, two transmission shafts drive the semiaxis at forward and backward drive axle two ends respectively by forward and backward main reduction gear, drive four drive wheels to move forward and backward.Forward and backward diff and center differential all match Limited slip differential, and during to prevent that in four drive wheels, any tire is unsettled, other tires also can redistribute moment of torsion, are gone out of difficult position by amphibious AWD all-terrain vehicle band by the friction force on tire and ground.
The object of patent of the present invention is to provide the general vehicle frame of a kind of amphibious AWD all-terrain vehicle, it is the general general vehicle frame of microlight-type amphibious AWD all-terrain vehicle of the aircraft ring frames of the theory design designing aircraft, greatly reduce own wt, to be increased in the load carrying ability when water surface travels.General all-terrain vehicle can not be navigated by water in water, and amphibious AWD all-terrain vehicle of the present invention not only will overcome because the difference of topography and geomorphology is to the extreme influence of all-terrain vehicle in-use performance on land, also to utilize the wheel rim of the buoyancy of equipped giant tire and equipped band blade and equipped can the screw propeller of fast assembling-disassembling, problem is passed through in the navigation solving the water surface and marsh cleverly, solve domestic floods, snow disaster, earthquake calamity and forest fire rescue to reach, the numerous areas such as frontier defense patrol do not have the situation of appropriate transport instrument.
Patent problem of the present invention should reach, the involved general vehicle frame of amphibious AWD all-terrain vehicle is a kind of microlight-type vehicle frame, be equipped with the giant tire of applicable various complex-terrain and the water surface that can exchange, make amphibious AWD all-terrain vehicle in the water surface, wetland and marsh, freely drive in the complex environment such as snowfield on ice and become a reality.

Detailed description of the invention
Described amphibious all-terrain vehicle takes type of drive and the integral structure of unique mid-AWD of longitudinal direction, to solve center of gravity in the environment in the water surface and marsh and load-carrying problem.
The power of amphibious all-terrain vehicle is by control clutch and change speed gear box, front propeller shaft and rear propeller shaft is divided in center differential part, before and after two transmission shafts drive respectively by forward and backward main reduction gear, the semiaxis at drive axle two ends, drives four drive wheels to move forward and backward.Before and after diff and center differential all match Limited slip differential, during to prevent that in four drive wheels, any tire is unsettled, other tires also can automatic distribute torque again, is gone out of difficult position by amphibious all-terrain vehicle band by the friction force on tire and ground.
The general vehicle frame of amphibious AWD all-terrain vehicle 4X4 shown in Fig. 1,2,3,4, the multi-connecting-rod separated suspension system that four covers are made up of spring damper (15) is set between frame assembly and wheel (28), make all-terrain vehicle when land complex environment advances, reduce jolt, held stationary.
A machinery space is had in the middle part of the general vehicle frame of amphibious AWD all-terrain vehicle, by (1), (2), (6), (12) surround, and strengthened by the assembling of four hexagonal bar irons (24) by driving engine crossbeam group (8), driving engine crossbeam group (8) is joined weldering four steel bushings (25) pass in order to hexagonal bar iron (24), at the correspondence position of (1) and (2) base and steel bushing (25), join weldering screw collar (26), to facilitate the fastening and dismounting of hexagonal bar iron (24), make the I&M of driving engine crossbeam group (8) simple.Engine assembly and driving engine crossbeam group (8) matched together, when driving engine needs dismounting and maintenance, as long as four binding bolts of disassembling and assembling engine crossbeam group (8), the object of engine assembly dismounting together with driving engine crossbeam group (8) can be reached, dismounting engine and maintenance work are simplified greatly.
At amphibious AWD all-terrain vehicle general vehicle frame front-wheel crossbeam group (5) and the inner main reduction gear (30) being all equipped with a band diff of trailing wheel crossbeam group (7), in change speed gear box, center differential (33) is connected with forward and backward driving-shaft assembly (31), (34) respectively, drive forward and backward half axle assembly (29) (35) at the diff two ends in forward and backward main reducing gear of drive axle (30), drive four drive wheels to move forward and backward.Front and back diff and center differential (33) all match Limited slip differential, during to prevent that in four drive wheels, any wheel (28) is unsettled, other wheels (28) also can redistribute moment of torsion, are gone out of difficult position by amphibious AWD all-terrain vehicle band by the friction force of wheel (28) with ground.
Amphibious AWD all-terrain vehicle is a kind of innovative product of principle uniqueness, its structure is simple, dismounting and easy to maintenance, driver behavior is easy, it is the amphibious transportation means of non-traditional format, it to design the basis that the general vehicle frame of microlight-type amphibious AWD all-terrain vehicle of the theory design of aircraft is its performance guarantee, is the general vehicle frame of microlight-type AWD that aircraft ring frames is general specially.Advancing freely in the water surface that amphibious AWD all-terrain vehicle cannot be passed through at other vehicle, wetland and region, marsh, is also applicable to snow and ice cover thin ice waters, the environment such as snowfield ice slush.
