Description
Technical field: the utility model belongs to the improvement of wheeled motor vehicle differential driver, particularly the four-wheel differentia transfer device.
Background technology: the diff of existing wheeled motor vehicle all is installed in respectively in propons and the back axle, and the self-propelled vehicle that diff is housed is easy to skid on the road surface of inclement condition, and can't cruising.When a tyre skidding of drive axle, when losing adhesive ability, tractive force will be descended significantly.And the oad of auxiliary gear box is big, and the carrying capacity of vehicle is poor.
In order to solve when the tyre skidding, the problem that tractive force descends significantly is equipped with differential locking-device usually on propons or back axle.But when current, trailing wheel all had a tyre skidding, vehicle still can't cruising, is difficult to avoid running into the awkward situation of skidding, getting deeply stuck in and can't travel.
Summary of the invention: the purpose of this utility model is to provide a kind of four-wheel differentia transfer device, can make self-propelled vehicle when passing through the road surface of inclement condition, prevents that vehicle wheels from skidding, and makes the self-propelled vehicle cruising.And when overcoming vehicle wheels and skid, can guarantee that vehicle has enough tractive forces.
The purpose of this utility model is achieved in that a kind of four-wheel differentia transfer device, comprise diff, the main shaft of perforation is installed in the conjoined outer shell of two difies, its middle part is installed with two-sided finishing bevel gear cuter by spline, two-sided finishing bevel gear cuter is meshed with the intermediate drive finishing bevel gear cuter of two difies respectively, the left half axle gear that one of them diff is meshed with the intermediate drive finishing bevel gear cuter, the endoporus of its hub splines and main shaft running-fit, the right axle shaft gear that another diff is meshed with the intermediate drive finishing bevel gear cuter, the endoporus of its hub splines and main shaft running-fit, the mouth of main shaft both sides and the hub splines of left half axle gear, by driving device fifth wheel side reducer, the bull gear that is provided with on conjoined outer shell is meshed with power input gear the hub splines of right axle shaft gear respectively.
During the utility model work, import into the diff through power input gear and bull gear engagement from the power of change speed gear box output, because two axle side gears of original design are merged into two-sided finishing bevel gear cuter in the middle of series connected two difies, therefore, reach the conjoined outer shell running that just can make two difies by a common bull gear, drive two mouths of main shaft and the hub splines of left half axle gear, the hub splines outputting power of right axle shaft gear.The hub splines of the left half axle gear of one of them diff outputs power to wheel reduction gear by connecting device, and by the travel situations of this wheel of clutch control; The hub splines of the right axle shaft gear of another diff is by connecting device this cooresponding wheel reduction gear that outputs power, by the operating condition of its wheel of clutch control.This wheel and last differential left semiaxis wheel driven are homonymy.The mouth of main shaft both sides is given the corresponding wheel reduction gear of homonymy by connecting device with transmission of power, and the operating condition of wheel is by clutch control.These two homonymy output shafts are locked mutually.
From the above, the utility model is locked the homonymy wheel mutually.When losing adhesive ability when any tyre skidding wherein, on the one hand, this wheel can not fly to change; On the other hand, the power on other three wheels is enough to drive to advance.Skid and when losing adhesive ability as two-wheeled, because the homonymy wheel locks mutually, its operation conditions is not only very little to the operation conditions influence of two wheels of an other side, can strengthen the propulsive effort of the single wheel that do not skid on the contrary.Therefore, can make normal vehicle operation equally; Situation is exactly that one group of wheel on the diagonal line or two wheels on the same drive axle (and two front-wheels or two trailing wheels) are when losing adhesive ability on the other hand, for the same side wheel, a wheel loses adhesive ability, the power of the wheel that another does not skid still exists, because the employing of this device can make its power strengthen to some extent, can impel vehicle to advance equally.When having only a wheel not run out of steam, for the homonymy slip wheel of locking mutually the power of the wheel that does not skid is increased considerably, and, lose adhesive ability for the wheel on the same drive axle, also can make the power of slip wheel not amid a sharp increase, if it is suitable that technical parameter is selected, also can make normal vehicle operation.Therefore, as long as there is a wheel not run out of steam, just can make vehicle '.
In addition, this device also has an obvious characteristics, when tyre skidding, is different from other a lot of vehicles and flies fast to change, and this has just improved the efficient of driving engine, and it is fully played.This device is locked the homonymy wheel mutually, when having differential promptly to turn between the wheel of both sides, can't be affected.
Because this device simplifies the structure, and has reduced oad, has increased the ground Clearance, variable at random drive form has effectively improved the carrying capacity of vehicle.
Description of drawings: Fig. 1 is the structural representation of the utility model embodiment 1, and Fig. 2 is the structural representation of the utility model embodiment 2.
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing, a kind of four-wheel differentia transfer device, comprise diff, as Fig. 1, shown in Figure 2, the main shaft 6 of perforation is installed in the conjoined outer shell 4 of diff 3 and diff 7, its middle part is installed with two-sided finishing bevel gear cuter 5 by spline, the finishing bevel gear cuter of two-sided finishing bevel gear cuter 5 two sides part respectively with diff 3, the intermediate drive finishing bevel gear cuter 15 of diff 7,14 are meshed, the wherein endoporus and main shaft 6 running-fits of left half axle gear 21 its hub spliness 16 of being meshed with intermediate drive finishing bevel gear cuter 15 of diff 3, the endoporus of right axle shaft gear 8 its hub spliness 13 that diff 7 is meshed with intermediate drive finishing bevel gear cuter 14 and main shaft 5 running-fits, the mouth of main shaft 5 both sides and the hub splines 16 of left half axle gear 21, the hub splines 13 of right axle shaft gear 8 is respectively by driving device fifth wheel side reducer, and the bull gear 2 that is provided with on conjoined outer shell 4 is meshed with power input gear 1.Embodiment 1 as shown in Figure 1, the middle part of main shaft 6 is installed with two-sided finishing bevel gear cuter 5 by the castellated shaft cooperation, the driving device of main shaft 6 both sides mouths is that the mouth of main shaft 6 both sides is installed with arc gear wheel 19,10 by castellated shaft respectively, arc gear wheel 19,10 is meshed with corresponding camber gear wheel shaft 20,9 respectively, connects corresponding wheel reduction gear respectively by camber gear wheel shaft 20,9; The hub splines 16 of left and right half gear 21,8,13 driving device is the hub splines 16 of left and right half gear 21,8, arc gear wheel 18 is installed respectively on 13,11, arc gear wheel 18, the corresponding ingear arc gear wheel of 11 difference green phases axle 17,12 is connecting corresponding wheel reduction gear, and the running condition of wheel is by clutch control.Go out to each wheel reduction gear owing to make transmission shaft form the X-shaped axle by driving device, vehicle by before two, two backs, the preceding left back right side, the left back and five kinds of drive forms of four-wheel in the preceding right side, can strain in various complex road surfaces, make normal vehicle operation.
