Description
Technical field
The present invention relates to a kind of machine power transfer device, specifically a kind of power that motor car engine can be sent after speed changer again through this transfer device transfer, can by power transfer individual transmission to transmission shaft before and after Motor Vehicle, also power can be transferred to transmission shaft before and after Motor Vehicle simultaneously simultaneously, thus the transfer device travelled under the enough Three models situations driven at independent front-wheel drive, front and back four-wheel drive and independent rear wheel of motor vehicle energy can be controlled.
Background technique
Motor Vehicle is as the term suggests be the various vehicles travelled under machine power drives, mechanokinetic obtains and obtains, so the vehicle no matter travelled on what road is all classified as Motor Vehicle in engine interior burning and electrical energy drive motor movement by fuel oil, combustion vapour.
Current Motor Vehicle gos deep into every field in our Working Life, the general level of Motor Vehicle is the mark of modern civilization, although the existing upper one-hundred-year history of the development of Motor Vehicle, but its conventional driving mode does not have great change, still still: (a) be rear wheel drive only, b () be front-wheel drive only, (c) rear wheel drive+front and back four-wheel drive, (d) front-wheel drive+front and back four-wheel drive.
Motor Vehicle is with the application of different driving mode: 1. rear wheel drive mode is mainly used on lorry, utilizes lorry loading weight, and driving is strong to pavement of road frictional force is large for trailing wheel; 2. front-wheel drive mode is mainly used in the compact car of engine behind front wheel, compact car railway carriage locational space is little, and loading is light, and under normal conditions, its front-mounted engine weight is all than goods weight, so front-wheel is all large than trailing wheel to pavement of road frictional force, therefore compact car adopts front-wheel drive mode mostly; 3. rear wheel drive+front and back four-wheel drive is mainly used on lorry, here front and back four-wheel drive is added, its practicability is that vehicle is when moistening by rough road road surface, climbing and pavement of road, before and after four-wheel drive simultaneously, adding tire to the frictional force of pavement of road makes vehicle easily pass through; 4. front-wheel drive+front and back four-wheel drive is mainly used in compact car, before and after it four-wheel drive function with above-mentioned 3rd consistent.
The four-wheel drive mode that current Motor Vehicle configures is mainly: rear wheel drive+front and back four-wheel drive; with front-wheel drive+front and back four-wheel drive etc. two kinds; before and after it, transmission shaft Placement also has two kinds: gears meshing is connected with center differential; gears meshing mode meshes together by controlling front and back shaft gear the object reaching four-wheel drive, and gear is separated and just becomes independent driving (front-wheel drive or rear wheel drive); Center differential mode is the object that before and after being regulated by differential mechanism, rotating speed of transmission shaft difference reaches four-wheel drive, when becoming independent driving (front-wheel drive or rear wheel drive), reaches its object by locked center differential.Existing gears meshing mode cost is low, and center differential mode complex structure cost is high, and these two kinds of driving mode only have two kinds of mode activated, (front-wheel or trailing wheel) driving+front and back four-wheel drive separately.
According to Chinese patent open source literature: a kind of four-wheel drive transporting tractor transfer case, application number: 200520117702.4, the applying date: 2005.9.9, Authorization Notice No.: CN2825351Y, authorized announcement date: on October 11st, 2006, patentee: Hainan Jinlu Agricultural Machinery Development Co., Ltd. and I am in application on November 07th, 2012: a kind of Motor Vehicle short-time four-wheel drives front and back independent axes output transfer case entirely, application number: 201210439681.2, dispatch sequence number: two applications of 2012110700513310 combine the new invention drawn.
Summary of the invention
The object of the present invention is to provide a kind of newly, low cost, starting motor-driven vehicle mechanomotive force after speed changer again through this transfer device transfer, Three models control mode can be gone out by transfer: front-wheel drive+front and back four-wheel drive+rear wheel drive mode can independently before and after drive short-time four-wheel independent axes to export transfer case, namely so-called independent axes exports is the transfer case of front and back output shaft not on same shaft axis.
For achieving the above object, of the present invention can independently before and after drive short-time four-wheel independent axes to export transfer case to comprise: transfer case casing, box cover, dial gear handlebar, dial block handle pole socket, dial block handle bowl cover, entering spindle, dial gear sliding gear, forerunner's transition gear, rear-guard transition gear, middle transition axle, middle transition axle setting sleeve, transition gear oriented side back-up ring, the needle bearing that transition gear assembling uses, back-up ring in the middle of transition gear location, forerunner's output shaft, rear-guard output shaft, forerunner's gear, rear-guard gear, shift fork guide rod, shift fork, sealing bearing (ball) cover, perforate bearing (ball) cover, bearing, rubber oil sea.
Of the present invention independently can have following advantage by front and back driving short-time four-wheel independent axes output transfer case.
1. simple and compact for structure, noise is little, transmission efficiency is high, cost is low, handling safety is reliable.The present invention compared with the prior art, gear handlebar is dialled in operation and shift fork only has one, just can realize four-wheel drive power divider Three models control mode: front-wheel drive+front and back four-wheel drive+rear wheel drive, breaching other four-wheel drive power divider only has two kinds of mode activated: (front-wheel or trailing wheel) driving+front and back four-wheel drive separately.
2. wide adaptability, purposes is wide.Apparatus of the present invention can be used for, on various motor vehicle, comprising agricultural transporting machinery, transportation machinery, carrying machine in mine etc., to improve the traveling reliability of various Transport Machinery.
3. Motor Vehicle in the process of moving, and driver can according to Motor Vehicle self carrying and pavement of road situation, the traveling drive pattern of Reasonable adjustment vehicle, has obvious help to reduction vehicle operating cost.
