Description
Technical field: the utility model relates to a kind of vehicle transmission gear, specifically is multi-functional AWD differential driver.
Background technology: open differential is made up of parts such as planetary wheel, planetary wheel carrier (differential gear box), axle side gears.The power of driving engine enters diff through transmission shaft, and the direct drive planetary wheel carrier drives left and right two-semiaxle gear by satellite gear again, drives left and right wheel respectively.The designing requirement of diff is satisfied: left half axle rotating speed+right axle shaft rotating speed=2 planetary wheel carrier rotating speeds.When automobile was kept straight on, left and right wheel equated to be in state of equilibrium with planetary wheel carrier three's rotating speed, and three's state of equilibrium is destroyed when automobile turning, causes the nearside wheel rotating speed to reduce, and the off-side wheel rotating speed increases.The diff principle can be referring among the CN02289386.5, and this diff model has reflected existing differential design profile generally.
The four-wheel drive system of existing automobile can be divided into two big classes basically: branch up-to-date style and full-time formula.1, branch up-to-date style structure be front propeller shaft or rear propeller shaft as axle drive shaft, where necessary, need be converted into four wheel drive by manual operation, at this moment it exists the not problem of differential or braking in a turn of between centers, exists handling safety.2, full-time formula structure both constantly just engine's motive power be sent to four drive systems on the wheel, existing this kind structure is carried out by the electronic induction servomechanism usually and is divided up-to-date style to change to full-time formula, thereby form the AWD pattern, this structure is when the speed of a motor vehicle of automobile is lower than a certain constant speed and spends, it is full-time pattern by the timesharing mode converting, being actually a kind of locking state, existing not differential equipower circulating phenomenon of between centers, is disadvantageous to fuel-economizing and safety; When the speed of a motor vehicle of vehicle was higher than the speed of setting, it just was converted into the timesharing drive pattern by the electronic induction servomechanism.
The utility model content: the utility model has solved that traditional timesharing drives that existing operating difficulties, carrying capacity are low, low, the defectives such as oil consumption is high, bad adaptability of speed during all-wheel drive, a kind of conversion operations link that reduces between timesharing driving and the all-wheel drive is provided, simplified full-time four wheel drive, increase a multi-functional full power output simultaneously, increased the multi-functional AWD differential driver of propulsion source for vehicle.The purpose of this utility model is achieved through the following technical solutions: described torque is imported from power intake A, through shift sleeve B, be divided into two-way output: the one tunnel connects full power output C, another road connects two cover difies, wherein the pinion carrier of the pinion carrier of first diff and second diff is fixed on the public housing of two difies, two axle side gears 1,2 of first diff connect two wheels in diagonal angle of vehicle respectively by transmission device, and two axle side gears 3,4 of second diff connect two wheels in diagonal angle in addition of vehicle respectively by transmission device.
The beneficial effects of the utility model are: owing to allow two conventional difies be in juxtaposition, wherein first diff has identical revolution speed simultaneously.Allow the moment of torsion of semiaxis output of first diff be delivered to the front right wheel of vehicle, the moment of torsion of another axle side gear of first diff is delivered to the back revolver of vehicle; The moment of torsion of an axle side gear output of second diff is delivered to the preceding revolver of vehicle, and the moment of torsion of another axle side gear output of second diff is delivered to the rear right wheel of vehicle.This 4 wheel driven state of the present invention need not artificial or electronics switches, and is pure physical construction, thus the personal safety problem that can avoid artificial incorrect operation or electronic failure to cause.It can allow automobile can both remain the 4 wheel driven state under any speed, and the quality that makes full use of automobile self makes it to become tractive force, has so both reached the purpose that reduces oil consumption, has possessed cross-country traveling ability again.Be to reduce the conversion operations link between timesharing driving and the all-wheel drive, reduced the unreliable factor of electric control operation, and to change electron steering all-wheel drive structure be the full-time four wheel drive structure of Purely mechanical, simplified full-time four wheel drive, brought into play the reliability and the safety of pure machinery.
Description of drawings: Fig. 1 is a structural principle scheme drawing of the present utility model.
Fig. 2 is that the utility model is applied to vehicle chassis annexation scheme drawing.
The specific embodiment: as shown in Figure 1 and Figure 2, described torque is imported from power intake A, through shift sleeve B, be divided into two-way output: the one tunnel connects full power output C, another road connects two cover difies, wherein the pinion carrier of the pinion carrier of first diff and second diff is fixed on the public housing of two difies, two axle side gears 1,2 of first diff connect two wheels in diagonal angle of vehicle respectively by transmission device, and two axle side gears 3,4 of second diff connect two wheels in diagonal angle in addition of vehicle respectively by transmission device.
As shown in Figure 1 and Figure 2, the axle side gear 1 of first diff is connected with a wheel in first diagonal angle wheel by transmission components such as gear pair, transmission shafts, and another axle side gear 2 of first diff passes through transmission components such as gear pair, transmission shaft and is connected with another wheel in first diagonal angle wheel; The axle side gear 4 of second diff is connected with a wheel in second diagonal angle wheel by transmission components such as gear pair, transmission shafts, and another axle side gear 3 of second diff passes through transmission components such as gear pair, transmission shaft and is connected with another wheel in second diagonal angle wheel.
Principle of work of the present utility model and mode of operation are as follows: the utility model can be realized an input five outputs.Be that torque is imported from power intake A, through shift sleeve B, be divided into two-way output: the one tunnel connects full power output C, another road connection two cover difies.
The first via is exported: B slides left by shift sleeve, connects gear pair CF1, and the common carrier that drive two cover difies are rotated, and transmission of torque is arrived axle side gear 1, axle side gear 2, axle side gear 3, axle side gear 4.Wherein, axle side gear 1 and axle side gear 2 mutual differentials, axle side gear 3 and axle side gear 4 mutual differentials, in this two covers diff, common planet carrier has identical public rotation speed n.In the first cover diff, the torque of axle side gear 1 is transferred to the right side wheel of propons by transmission components such as transmission shaft C1, tapered gear pair A1, constant velocity driving shaft D1; The torque of axle side gear 2 is transferred to the revolver of back axle by transmission components such as transmission shaft C2, tapered gear pair A2, constant velocity driving shaft D2.In the second cover diff, the torque of axle side gear 3 is transferred to the revolver of propons by transmission components such as gear pair CF2, transmission shaft C3, tapered gear pair A3, constant velocity driving shaft D3; The torque of axle side gear 4 is transferred to the right side wheel of back axle by transmission components such as gear pair CF3, transmission shaft C4, tapered gear pair A4, constant velocity driving shaft D4.Promptly have: 2n=n1+n2=n3+n4.In this device, gear pair CF2 equates that with the speed ratio of gear pair CF3 the speed ratio of tapered gear pair A1, A2, A3, A4 equates.
The second tunnel output: B slides to the right by shift sleeve, secondary CF1 of out-of-gear connects the full power output shaft, and this moment, vehicle was no longer walked, the device of torque output C, as being used as purposes such as promoting high-pressure hydraulic pump, high-pressure oil pump, marine propulsion to other other function and usage.
