Shown in Figure 7, front drive axle is consistent with back driving axle structure, and forerunner's wheel that travels is less than the rear-guard wheel that travels, and differential mechanism travels and normally travels and have without differential the velocity ratio mating while taking turns in front drive axle and back driving axle driven, as pressed in Fig. 1 as shown in C direction, driving shaft 9 is rotated counterclockwise under powered attendant-controlled wheelchairs driving, drive forerunner's planet wheel 23 to rotate by the integrated sun gear 24 of forerunner, drive rear-guard planet wheel 14 to rotate by the integrated sun gear 29 of rear-guard, under the effect of external motion resistance, forerunner's planet wheel 23 impels the sliding fixing frame 13 of limit to have the trend being rotated counterclockwise by forerunner's planet wheel supporting component 1, and rear-guard planet wheel 14 is to limitting sliding fixing frame 13 to have the trend of impelling it to turn clockwise, so rear-guard planet wheel 14 to the active force of limitting sliding fixing frame 13 with forerunner's planet wheel 23 to limitting the force direction of sliding fixing frame 13 contrary, power is inputted rear portion through the wheeled gear ring 10 of forerunner's planet wheel 23 driving gear through driving shaft 9, and drive front wheel driving mechanical axis 34 to rotate transmission of power to front drive axle part by forerunner's gear 6, another part drives rear driving mechanical axis 18 through rear-guard planet wheel 14, and by the internal spline on rear driving mechanical axis 18 by transmission of power to back driving axle part, concrete running state is as follows: suppose that the sliding fixing frame 13 of limit is relatively static, driving shaft 9 passes through the angular velocity of the wheeled gear ring 10 of forerunner's planet wheel 23 driving gear: ω with rated speed
1,
Now, the travel angular velocity of the gear type gear ring 10 that feeds back to differential mechanism of gear type gear ring 10 end outsides is: ω
2;
The sliding fixing frame 13 of limit is relatively static, and driving shaft 9 drives the angular velocity of rear driving mechanical axis 18: ω by rear-guard planet wheel 14 with rated speed
3;
Now, the travel angular velocity of the rear driving mechanical axis 18 that feeds back to differential mechanism of rear driving mechanical axis 18 end outsides is: ω
4;
When forerunner's wheel 23 that travels is subject to external influence and impels ω
2< ω
1time, forerunner's planet wheel 23 drives the sliding fixing frame 13 of limit to rotate by forerunner's planet wheel supporting component 1 power, and the rotation of the sliding fixing frame 13 of limit will speed up the driving of rear-guard planet wheel 14 to rear driving mechanical axis 18, i.e. ω
3become large, to increase, rear-guard is travelled and takes turns 14 driving; Otherwise, when the rear-guard wheel 14 that travels is subject to external influence and impels ω
4< ω
3time, rear-guard travels wheel 14 certainly will be by transmission of power to the sliding fixing frame 13 of limit, and the rotation of the sliding fixing frame 13 of limit will speed up the travel driving of 23 pairs of gear type gear rings 10 of wheel of forerunner, i.e. ω
1become large, to increase, forerunner is travelled and takes turns 23 driving, with motivational drive between centers differential before and after realizing;
In the time that the sliding fixing frame 13 of limit rotates, the sliding projection 22 of drive limit determines projection 30 on a left side and determine to swing and rotate in a circumferential direction between projection 35 in the right side, as shown in Figure 6, the sliding projection 22 of limit, leftly determine projection 30 and the right side and determine to be processed with respectively on projection 35 groove 36, inclined-plane 37 and boss 38, and right determine projection 35 and a left side and determine projection 30 installation of staggering, the height of boss 38 is s, and groove 36 width a are three times of boss 38 width b; Left boss center and right groove center-aligned of determining projection 35 of determining projection 30, a left side is determined projection 30 and is greater than with right centre distance of determining projection 35 maximum position of limitting sliding projection 22, the sliding projection 22 of limit is determined projection 30 at a distance of t with left, the sliding projection 22 of limit is determined projection 35 at a distance of d with right, wherein (t+d) <s, t+d has determined to limit with value size the limit slip control effect processed of sliding projection 22, t+d's is larger with value, limit slip control effect processed is poorer, t+d's is less with value, the sliding effect of limit is better, but the too small meeting with value of t+d has influence on differential effect; In the sliding projection 22 of limit, be provided with mobile boss 1., mobile boss 2. and mobile boss 3., below with the mobile boss of the sliding projection 22 of limit in Fig. 6-1 1. act as example, current back driving axle has while slightly relatively trackslipping, the sliding projection 22 of limit rotates, due to the effect 1. of mobile boss, the sliding projection 22 of limit determine projection 30 and the right side and is determined to move left and right and rotate in chute that projection 35 forms on a left side, moving to from Fig. 6-1 position of Fig. 6-2, the sliding projection 22 of limit has rotated a lug boss position in a circumferential direction, has moved to the right in the axial direction x+y distance; Moving to from Fig. 6-2 position of Fig. 6-3, limit sliding projection 22 to rotate in a circumferential direction a lug boss position, move to the left in the axial direction x+y distance; Because the sliding projection 22 of limit is in the time that its differential moves left and right, moves left and right and reduced its rotational speed at chute axis, and then playing the effect of slide limiting differential simultaneously.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
