Abstract
The utility model relates to an improvement of a wheeled power-driven vehicle driving device, in particular to an improvement of a four wheel differential driving device. The utility model comprises a front axle differential and a rear axle differential, which are driven by a transfer case through a drive shaft. Bevel gears are respectively arranged on the half axle gear shafts at the same side of the front axle differential and the rear axle differential, and a bevel gear arranged at the shaft end of a drive shaft connected into a whole through a clutch is respectively meshed with the bevel gears on two half axle gears. The common four-wheel drive vehicle can be modified to be a high-bed four-wheel drive vehicle through the installation of the device. When a vehicle drives on the road surface in bad conditions, such as a muddy road surface, a snow and ice road surface, a desert road surface, etc., and when one of the front wheels and the rear wheels respectively skids, the power of the wheel which does not skid is not reduced, thus the vehicle can keep a normal driving.
Description
Technology neck or: the utility model belongs to the improvement of wheeled motor vehicle actuating device, particularly improved self-propelled vehicle four-wheel drive device.
Background technology: its power transmission line of the vehicle of common four wheel drive is such: the power of driving engine output passes to forward and backward bridge diff drive wheels by auxiliary gear box respectively by transmission shaft after the change speed gear box speed change.The weak point of this structure is that then the power of slip wheel will not reduce significantly when front-wheel and trailing wheel respectively have a tyre skidding.When vehicle sailed on the abominable road surface such as marshy area, ice-snow field, desert, vehicle just was difficult to travel.
Summary of the invention: the purpose of this utility model is to provide a kind of improved self-propelled vehicle four-wheel drive device, this device is installed can make common 4Wdvehicle transform cross-country traveling ability 4 wheel driven vehicle as, improve the through performance of vehicle, when front-wheel and trailing wheel respectively had a tyre skidding, the power of the wheel that does not skid can not reduce.When vehicle sails on the abominable road surface such as marshy area, ice-snow field, desert, can prevent tyre skidding, make normal vehicle operation.
The purpose of this utility model is achieved in that a kind of improved self-propelled vehicle four-wheel drive device, comprise front axle differential and rear-axle differential that auxiliary gear box drives respectively by transmission shaft, on the side gear shaft of front axle differential and rear-axle differential homonymy conical gear is installed respectively, the conical gear that its axle head of the transmission shaft that connects as one by power-transfer clutch is installed is meshed with conical gear on two side gear shaft respectively.
After common 4 wheel driven vehicle had been installed the utility model, the side gear shaft of the forward and backward bridge diff homonymy of vehicle was connected to an integral body by power-transfer clutch, transmission shaft and conical gear pair.When current two-wheeled or back two-wheeled skidded, the vehicular drive structure before the repacking can make normal vehicle operation, and the vehicular drive structure after the repacking can make normal vehicle operation equally.When current, rear wheel respectively has one to skid,, make the interlock of homonymy wheel by power-transfer clutch bonded assembly transmission shaft transferring power.In this case, the power of the not slip wheel in the interlock wheel can not reduce because of the loss of power of slip wheel, equally can make normal vehicle operation yet.After common 4Wdvehicle has been installed the utility model, the performance of vehicle has obtained further improvement on original basis, improved the through performance of vehicle, and the turning efficiency of vehicle can not be affected, the power of driving engine can be fully played.When vehicle sails on the abominable road surface such as marshy area, ice-snow field, desert, prevent tyre skidding, make normal vehicle operation.
Description of drawings: accompanying drawing is a structural representation of the present utility model.
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing, a kind of improved self-propelled vehicle four-wheel drive device, comprise front axle differential 1 and rear-axle differential 4 that auxiliary gear box 3 drives respectively by transmission shaft 2, side gear shaft 13 at front axle differential 1 and rear-axle differential 4 homonymies, conical gear 12 is installed respectively on 5,6, the transmission shaft 10 that links together by power-transfer clutch 9, the conical gear 11 that 8 its axle heads are installed, 7 respectively with two side gear shaft 13, conical gear 12,6 on 5 is meshed.Because the utility model is to convert on the basis of common 4Wdvehicle, repacking is convenient, simple, and required cost is low, highly versatile, extensive market.
Claims (1)
