Abstract
Disclosed is a four-wheel differential power dividing device. In the structure of the utility model, a gear arranged on a power output shaft in a power dividing box is meshed with the big gear ring of a differential; a gear arranged on a right half shaft gear shaft sleeve of the differential is simultaneously meshed with a gear arranged on a rear left wheel drive shaft and a gear arranged on a drive shaft at the other side; a gear arranged on the other end of the drive shaft is meshed with the big gear of a compound gear arranged through a bearing on a front left wheel drive shaft sleeve; the internal gear ring of a shift sleeve matched with a spline shaft of the front left wheel drive shaft sleeve is meshed with the small gear of the compound gear; the front left wheel drive shaft sleeve is arranged on a front right wheel drive shaft through a bearing; the left half gear shaft of the differential is connected with the front right wheel drive shaft by a connecting device; a gear arranged on a drive shaft arranged by a bearing in a right half gear shaft sleeve of the differential is meshed with a gear of a rear right drive shaft. The utility model has simple structure, small size and good traffic-ability which means in the structure, if a wheel or wheels skids, the power of the other non-skidded wheels still exist.
Description
Technical field: the utility model belongs to the improvement of wheeled motor vehicle drive unit, particularly the four-wheel differentia transfer device that is driven by a differential mechanism.
Background technique: present most of motor vehicle all are equipped with differential mechanism in order to improve passing ability on forward and backward bridge, and vehicle driving wheel on abominable road surface such as mire, ice and snow that differential mechanism is housed is easy to skid, and can't cruising.Be head it off, generally adopt differential lock restriction differential,, the both sides jack shaft is become one until differential mechanism is locked.But in this case, differential mechanism is in a single day locked, and vehicle just loses and turns to function, can only straight-line travelling.The device of this restriction differential, mechanism's complexity, boundary dimension is big, and the ground Clearance of vehicle chassis is reduced, and cost of production is high especially, and is difficult in maintenance, and when wheel-slip of the ransaxle that is unkitted differential lock, tractive force descended significantly.
Summary of the invention: the purpose of this utility model is to provide a kind of four-wheel differentia transfer device that is driven by a differential mechanism, and not only simple in structure, boundary dimension is little, cost is low, and when wheel-slip, the power of other non-slip wheels still exists, and guarantees normal vehicle operation.
The purpose of this utility model is achieved in that a kind of four-wheel differentia transfer device that is driven by a differential mechanism, comprise the differential mechanism of installing in the transfer case, the gear of installing on the power input shaft in the transfer case is meshed with the bull gear of differential mechanism, the gear installed on the differential mechanism right axle shaft gear bush is meshed with the gear installed on the transmission shaft of the gear installed and opposite side on the revolver transmission shaft of back simultaneously, the gearwheel of the compound gear by Bearing Installation on the gear that the transmission shaft the other end is installed and the preceding revolver driving sleeve is meshed, be meshed with the small gear of compound gear with the splined shaft of preceding revolver driving sleeve its ring gear of engagement cover that matches, before the revolver driving sleeve by Bearing Installation on the front right wheel transmission shaft, the left semi gear shaft of differential mechanism is connected with the front right wheel transmission shaft by connection set, is meshed with the gear of right back transmission shaft by the gear of installing on the transmission shaft of Bearing Installation in right half gear bush of differential mechanism.
The utility model has only been used a differential mechanism, has replaced original general two differential mechanisms installing on the bridge of front and back, simplifies the structure, and has correspondingly increased the ground Clearance of vehicle chassis.The left and right half gear of differential mechanism of the present utility model is being controlled the transmission shaft of homonymy wheel respectively, therefore can make the homonymy wheel interlock of vehicle.When vehicle has a wheel-slip, because four wheels are by a differential controls, do not allow the rotating speed between wheel to differ greatly, so slip wheel can not fly to change, the output power of motor can not decrease like this, the power of other three wheels still exists, and is enough to order about vehicle and advances.When two wheels lost adhesion, the opposite side wheel can not descend because of the adhesion of slip wheel, and its power reduces, and can increase to some extent on the contrary, can make normal vehicle operation.Another kind of situation is that two wheels (i.e. two front-wheels or two trailing wheels) on the same ransaxle are when losing adhesion, in this case, for the homonymy wheel, slip wheel will not obtain the power with bigger differential gear output from differential mechanism, and the power of two wheels that do not skid can make normal vehicle operation.This variable at random drive form has effectively improved the passing capacity of vehicle, because this class device allows the both sides wheel of vehicle to have speed difference, so can not influence the steering behaviour of vehicle.The power of motor is utilized well.
