Description
Technical Field
The invention relates to a transfer case structure, and belongs to the technical field of transmission.
Background
The hinged dumper is special equipment specially applied to severe working conditions such as raininess, muddy road, rugged road and the like, and is provided with a front frame and a rear frame which are connected through a hinged body or a swinging ring, wherein the front frame is provided with an engine, a gearbox, a transfer case, a cab and other parts, is supported by virtue of a front axle, the rear frame is provided with a cargo compartment, and is supported by virtue of a middle axle and a rear axle. Fig. 1 is a schematic diagram of power transmission of an articulated dump truck. The special use condition requires the articulated dumper to have excellent driving capability and off-road capability, most of the articulated dumper is driven by three axles, when the cargo box is empty, the front axle bears about 50% of the weight of the whole dumper (empty weight), but when the cargo box is full, the three axles bear basically the same weight, or the middle axle and the rear axle are slightly higher. The transfer case is a power distribution device of the hinged dumper, is positioned between a power source (an engine and a gearbox) and a power execution part (a drive axle) and plays a vital role.
At present, transfer cases adopted by articulated dumpers have the following problems:
1. The torque distribution can not be customized and can only be output in front and rear 1:1, but the front and rear output torques are better when distributed in about 1:2 according to the gravity distribution of the articulated dump truck, and the optimal state is distributed according to the bearing of each bridge in the same proportion.
2. The differential is located on the transfer case lower most shaft, with the front and rear outputs coaxial, and this arrangement presents two problems: a. the front and rear space size of the output shaft at the lowest part of the transfer case is increased, the transmission shaft from the transfer case to the front axle is shortened, the angle of the transmission shaft is greatly affected by the up-and-down floating of the front axle, and the processing difficulty of the shorter transmission shaft is high, so that the cost is high; b. the rear output height of the transfer case is lower, so that the ground clearance at the lower part of the hinge body is very low, and the trafficability of the whole vehicle is affected.
3. The differential lock adopts a jaw differential lock or a differential lock without the differential lock, and when the jaw differential lock applies motion, certain impact and mechanical damage exist, and the jaw differential lock is required to be applied in a low-speed or static state; if the differential lock is not provided, tires on two sides of one drive axle can slip simultaneously, so that the whole vehicle can lose driving capability.
4. When the whole vehicle suddenly loses a power source (such as flameout of an engine) or the main steering pump works abnormally, the whole vehicle loses steering capacity or has insufficient steering force, so that the whole vehicle is out of control, and certain potential safety hazard exists.

Power is transmitted through the input shaft 2 to the planetary differential 3, and the planetary differential 3 distributes power to the rear output gear assembly i 5 and the front output gear assembly i 6; the rear output gear assembly I5 is meshed with the rear output gear assembly II 7, and power is output to the hinge body N6; the front output gear assembly I6 is meshed with the front output gear assembly II 8, the front output gear assembly II 8 is nested on the rotating shaft of the rear output gear assembly II 7 through a bearing, and the rotating shaft of the rear output gear assembly II 7 only plays a supporting and positioning role on the front output gear assembly II 8, and the rotating speeds of the front output gear assembly II and the rear output gear assembly II have no influence on each other; the front output gear assembly II 8 is meshed with the front output gear assembly III 9, and power is output to the front axle N11; the emergency steering pump 10 is directly connected to the rotating shaft of the rear output gear assembly II 7, and the emergency steering pump and the rear output gear assembly rotate at the same speed; the planetary differential mechanism 3 and the inter-axle differential lock 4 are positioned on the uppermost shaft of the transfer case and coaxial with the power output shaft, so that the front-rear space size of the lowermost shaft of the transfer case is reduced, and the output from the transfer case to the front axle can be improved; the rear output gear assembly II and the front output gear assembly III are not coaxial, the rear output gear assembly II is located on the middle shaft of the transfer case, the front output gear assembly III is located on the lowest shaft of the transfer case, the height of the rear output transmission shaft N5 is effectively improved, the height of the hinge body N6 can be correspondingly improved, and the passing performance of the whole transfer case is improved.
The emergency steering pump 10 has the function of providing a sufficient power source for a steering system by means of rotation of wheels when a power source is suddenly lost (such as an engine is turned off) in the running process of the whole vehicle, and the emergency steering pump 10 is reversely towed to rotate, so that the vehicle has a certain steering capability and is ensured to safely park in a roadside or other relative safety area.
As shown in fig. 3, the planetary differential 3 is located on the uppermost axle of the transfer case, coaxially with the transfer case input shaft 2. The planetary differential 3 comprises a planet carrier 3-1, a planetary gear set 3-2, a planetary gear 3-3, a sun gear assembly I3-4 and a sun gear assembly II 3-5.

As shown in fig. 5, the power transmission schematic diagram of the whole vehicle after the transfer case is adopted, it can be seen that the transmission shaft N12 from the transfer case N4 to the front axle N11 is lengthened, the influence of the up-and-down floating of the front axle N11 on the angle of the transmission shaft N12 is reduced, and the manufacturing difficulty and cost of the transmission shaft N12 are reduced; the transfer case is highly promoted after outputting, and the height of the articulated body N6 improves, effectively increases the ground clearance of articulated body N6 lower part, improves whole car trafficability characteristic.
The hinged dumper is a vehicle with a front frame, a rear frame and a hinged body, and is generally of a three-shaft full-drive structure, wherein the front frame is provided with a bridge, the rear frame is provided with two bridges, and the front bridge, the middle bridge and the rear bridge bear basically the same load when in full load or the middle bridge and the rear bridge bear slightly higher load. For the two-axle hinged dumper with smaller rated load in the current market, the transfer case in the prior art can be satisfied, and certainly, if the front and rear drive axles of the two-axle dumper have larger bearing differences, the transfer case is more reasonable. The transfer case is also suitable for articulated dump trucks with more than three axles which may appear in the future, and the differential gear train is reasonably proportioned according to the bearing proportion, so that the reasonable distribution of front and rear driving torques is realized.
