Abstract
The utility model relates to a four-wheel full-driving automobile pivot steering system which structurally comprises a front drive axle, a back drive axle, front drive wheels, back drive wheels, a steering knuckle and an electric/gas control unit. The front drive axle and the back drive axle are both steering drive axles, steering power-assisted oil cylinders for controlling steering are connected to the four drive wheels respectively, and the electric/gas control unit controls the steering power-assisted oil cylinders to operate. Differential locks are installed on the front drive axle and the back drive axle respectively, shaft head clutches are installed on the four drive wheels respectively and used for connecting or disconnecting power transmitted from axel shafts in the rear drive axles to the drive wheels. According to the four-wheel full-driving automobile pivot steering system, the driving directions of the drive wheels can be changed, the automobile pivot steering mode can be achieved, the zero-turning-radius aim can be achieved, the pivot steering capacity of an automobile can be achieved, and the maneuvering performance can be good. The four-wheel full-driving automobile pivot steering system is suitable for various four-wheel full-driving automobiles such as cross country automobiles, special type automobiles, tunnel cleaning automobiles, expressway surface maintenance automobiles and roadway fire fighting trucks.
Description
Technical field
The utility model relates to a kind of automobile steering system, and specifically a kind of four-wheel drives automobile in-place steering swivel system entirely.
Background technology
Well-known four-wheel drives motor turning (4WS) pattern entirely, and the first is that single-wheel turns to pattern, front-wheel or rear-axle steering (FWS/RWS), and for zero phase turns to, turn radius is large.The second is standard four-wheel steering pattern, and trailing wheel and front-wheel all participate in turning to and switched in opposite, and for phase reversal turns to, turn radius tightens up and diminishes, thus make to turn to more accurate.The third is " crab row turns to " pattern, and trailing wheel is identical with turning to of front-wheel, for same-phase turns to, can make automobile sliding to a side and towards constant.
Pivot stud, has zero turn radius, makes automobile have spot turn ability, and vehicle mobility can be best, for all kinds of 4 wheel driven automobiles, for turning around in narrow and small region or operation provides great convenience.
Pivot steering system drives almost not application on automobile entirely at existing four-wheel, and on four-wheel small engineering machinery, apply more, as glide steering loader, it passes through static hydraulic drive system, by driving engine, controllable capacity pump, left/right HM Hydraulic Motor, chain-wheel mechanism, drive two wheels of left/right side, as two motor reverse operations, can realize pivot stud function, but due to its complicated structure, be not suitable for entirely driving on automobile product and applying at four-wheel.
Utility model content
The purpose of this utility model is just to provide a kind of four-wheel and entirely drives automobile in-place steering swivel system, solving existing pivot steering system complex structure, manoevreability is poor and the problem that is unsuitable for installing and using on automobile.
The utility model is achieved in that a kind of four-wheel all wheel drive automobile pivot steering system, comprise front driving axle, rear driving axle, front driving wheel, rear drive sprocket, steering swivel, electricity/gas control unit, described front driving axle and described rear driving axle are steering drive axle, on two described front driving wheels and two described rear drive sprockets, be connected to respectively and control the steering jack turn to, steering jack moves described in described electricity/gas control unit controls processed; On described front driving axle and described rear driving axle, be separately installed with differential locking-device, on described front driving wheel and described rear drive sprocket, clutch of spindle nose is all installed, described clutch of spindle nose is for engaging or cut off the power that is delivered to drive wheel from the semiaxis of drive axle.
The utility model by four independently steering jack control respectively four drive wheels, driving direction with change wheel, make four wheels be " toe-in ", thereby the 4th kind that realizes automobile turns to pattern---pivot stud pattern, reach zero turn radius, make automobile have spot turn ability, maneuvering performance is best.The utility model is applicable to all kinds of four-wheels and entirely drives automobile, comprises cross-country car, speciality car, various MPV (Multi-Purpose Vehicle) (as tunnel pickup sweeper, system on expressway pavement maintenance car, tunnel fire extinguishing tanker etc.), for it turns around in narrow and small region or operation provides convenience.The utility model is simple in structure, and manufacture and use cost are low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model is used state reference map.
In figure: 1, front driving axle, 2, rear driving axle, 3, front driving wheel, 4, rear drive sprocket, 5, differential locking-device, 6, clutch of spindle nose, 7, steering jack, 8, electricity/gas control unit, 9, steering swivel.
The specific embodiment
As shown in Figure 1, the utility model comprises front driving axle 1 and rear driving axle 2, in the two ends of front driving axle 1 tap, by steering swivel 9, connect front driving wheel 3, in the two ends of rear driving axle 2 tap, by steering swivel 9, connect rear drive sprocket 4, on front driving axle 1 and rear driving axle 2, be separately installed with differential locking-device 5, on front driving wheel 1 and rear drive sprocket 2, clutch of spindle nose 6 is all installed, clutch of spindle nose 6 is for engaging or cut off the power that is delivered to drive wheel from the semiaxis of drive axle.On four drive wheels, be separately installed with steering jack 7, the cylinder rod of each steering jack 7 is connected with the steering swivel 9 of connected drive wheel respectively, and steering jack 7 is controlled by electricity/gas control unit 8.
As shown in Figure 2, when automobile in-place turns to, electricity/gas control unit 8 instruction hydraulic efficiency pressure systems, make four independently steering jack 7 work, drive steering swivel and four wheels of front driving axle 1 and rear driving axle 2 to open, form " toe-in " shape, simultaneously, the forward and backward drive axle of electricity/gas control unit 8 synchronic command hangs up driven at low speed, two clutch of spindle noses of homonymy 6 disconnect transmission, and as two of automobile left side wheels advance, and the forward and backward drive wheel on right side disconnects power by clutch of spindle nose 6, become flower wheel, automobile is realized flicker.Otherwise as two, right side wheel advances, and the forward and backward drive wheel in left side disconnects power by clutch of spindle nose 6, becomes flower wheel, automobile is realized flicker.For reducing wear on tyres, can hocket by low-forward range or reverse gear conversion.
