Description
Technical field
The utility model relates to a kind of automobile-used transmission system, and particularly a kind of automobile-used front and back drive the integrated type gearbox.
Background technique
The used power transmission mechanism of powered vehicle is made up of transmission assembly, gearbox output adpting flange, transmission shaft, transfer case input adpting flange, transfer case assembly, transfer case rear-guard output flange, rear-guard transmission shaft, transfer case forerunner output flange, forerunner's transmission shaft before and after the present known car sedan-chair formula; Transmission assembly is separated with the transfer case assembly; Between need transmission shaft, flange to connect; The effect of transmission assembly is single with transmitting behind the engine power bending moment backward, and transfer case becomes forward back axle with the power-converting of gearbox input again and transmits simultaneously.Must increase a transfer case assembly, a transmission shaft, two adpting flanges like this, whole speed change drive mechanism is at random.Cause car load to process this increase, low, the transfer case assembly rate of fault height of transmission efficiency.
On aspect the automobile-used transmission system, we have retrieved following open source literatures, but some use narrow limitation of all corresponding existence.For example:
1, Chinese patent; Application number: CN98800950.1, title: be used for the drive unit of continuously variable gear box, summary: this invention is used for controlling the drive unit of speed ratio of the continuously variable gear box of the vehicle that internal-combustion engine is housed; This drive unit comprises two sleeves; They are respectively equipped with leading screw and internal thread, and both are bonded with each other, and make to relatively rotate to become relative translation; Sleeve comprises circular groove, and they maximum reciprocating typely rotate relatively freely sleeve when running through state and do not do any translation when sleeve is in; The function of said drive unit is preferably undertaken by the used same motor of cranking internal combustion engine, and the employed gearbox volume of this drive unit is bigger, does not meet present gearbox to the miniaturization Development Trend.
2, Chinese patent; Application number: CN200910114346.3; Title: a kind of vapour that does not have independent transfer case, summary: this invention provides a kind of forward and backward driving force export structure of automobile and tractor that does not have independent transfer case, comprises vehicle frame, motor, propons, front axle propeller shaft, back axle and rear axle propeller shaft; It is characterized in that: the clutch end at vehicle motor is provided with the combined speed changer of exporting before and after the band; This combined speed changer clutch end forward connects with propons through front propeller shaft, and clutch end backwards passes through rear propeller shaft and connects with back axle, its forward or power transmission direction backwards directly control by the operating handle of putting into gear.The present relatively structure of this power output structure has been saved a transmission shaft, transfer case, still, and this invents structural instability, needs long transmission shaft could accomplish above-mentioned functions, increases the consumption of power.
3, Chinese patent; Application number: CN99125484.8 title: a kind of agricultural automobile engine behind front wheel, bridge diagonal angle, front and back drive system, summary: a kind of agricultural automobile engine behind front wheel, bridge diagonal angle, front and back drive system, a kind of agricultural automobile engine behind front wheel, bridge diagonal angle, front and back drive system; Still use combination transmission case with clutch, speed change, differential function; And be fixed on propons top vehicle frame, and driving through driving belt by front-mounted engine, transmission case one side output shaft directly drives this side front wheel; The opposite side output shaft drives this rear flank wheel indirectly through transmission device, and its differential mechanism is as shaft space difference speed.This scenario-frame is simple, cost is lower, but still adopts traditional drive mechanism and mode, therefore still needs to adopt transfer case, thereby has increased fabricating cost.
Summary of the invention
The purpose of the utility model provides a kind of automobile-used front and back and drives the integrated type gearbox; To install the transfer case assembly in addition separately additional with driving transmission vehicle transmission system before and after overcoming existing car sedan-chair formula; The shortcoming that variable ratio drive system disperses, transmission efficiency is low, rate of fault is high, the car load manufacture cost is higher makes to reach that gearbox designs is compact, easy to operate, rate of fault is low, transmission efficiency is high, reduces manufacture cost, alleviates the purpose of vehicle total quality.
The scheme of the utility model is through such realization: a kind of automobile-used front and back drive the integrated type gearbox; Comprise housing, transfer gear level, active output shaft and transfer output shaft; Be fixed with initiatively output gear on the active output shaft in the housing; Be fixed with the transfer output gear on the transfer output shaft; The housing internal fixation has transfer power shift gear axle, is fixed with the transfer power shift gear on the transfer power shift gear axle, and the transfer power shift gear meshes with active output gear and transfer output gear respectively through driving gear; The transfer power shift gear is connected with transfer selector fork one end, and the transfer selector fork the other end is connected with the transfer gear level through the transfer shift rod.
The working principle of the utility model is following: when vehicle motor starts; Initiatively output shaft rotates, and drives the active output gear simultaneously and rotates, and initiatively output gear drives the rotation of transfer power shift gear through driving gear; The transfer power shift gear drives the transfer output gear through driving gear again and rotates; At this moment, initiatively output shaft can send power to the transfer output shaft, and vehicle is four-wheel drive.Stir the transfer gear level; Divide and move the motion of pole spacing promotion transfer shift rod; The transfer shift rod drives the transfer selector fork and moves, and the transfer power shift gear is driven on the transfer driving gearshaft and moves, transfer power shift gear and driving gear cancellation engagement this moment; Power can't be sent to the transfer output shaft from the active output shaft, and this moment, vehicle became two wheel drive by four-wheel drive.Vehicle is become four-wheel drive by two wheel drive only need stir the transfer gear level once more, transfer power shift gear and transmission gear engagement are got final product.
The above active output gear and transfer constant mesh gear are connected with a joggle, and said transfer output gear is connected with a joggle with dividing nutating gear, and said transfer constant mesh gear, transfer power shift gear and branch nutating gear are connected with a joggle successively.
The utlity model has following beneficial effect:
1. the utility model is simple in structure, can so that automobile-used front and back drive become integrated type speed box assembly compact structure, easy to operate, rate of fault is low, easy to maintenance.
