Background technology
In prior art, engine balance forklift driveline gear box assembly is to front axle drive structure, what adopt is that two pieces joint yoke oppositely welds design, as shown in Figure 1, driving-shaft assembly pitches 1 by bridge end boss, journal cross assy 2, circlip 3, convex joint yoke 4, recessed joint yoke 5, case end boss fork 6 composition, its convexity joint yoke 4 adopts to weld with recessed joint yoke 5 and designs, this driving-shaft assembly belongs to rigidity universal-joint-pin type universal driving-shaft assembly, connection mode is that bolt connects, seam is located, torque is born by bolt, the process that the moment of torsion completing transmission assembly and front driving axle transmits.Its weak point is: the factor by engine balance forklift complete machine structure space relative narrowness affects, driving-shaft assembly design size is very short, bridge end boss fork 1, case end boss fork 6 and convex joint yoke 4, recessed joint yoke 5 center high size can not be unrestrictedly short due to blank and stiff problem, and need convex, recessed two kinds of joint yokes weld, there is the limitation of this kind of project organization, due to welding process application, this driving-shaft assembly balance is poor, design life differs, there are vibrations, the early faults such as abnormal sound, it is the major cause causing driving unit fault rate occurred frequently, this just has higher requirements for quality to driving-shaft assembly parts machining and technique.
Summary of the invention
The technical problems to be solved in the utility model is: provide the engine balance forklift driving system duplex V shape drive mechanism that a kind of structure is simple, easily manufactured, strong shock resistance, reliability are high, the welding transmissions axle assembly balance solved in the narrow space environment of existing engine balance forklift driving system is poor, design life differs, and occurs the problem of vibrations, abnormal sound.
In order to solve the problems of the technologies described above, the technical solution of the utility model there is provided a kind of engine balance forklift driving system duplex V shape drive mechanism, comprise front driving axle, transmission assembly, it is characterized in that, one end that one end and the bridge end boss of described front driving axle are pitched is connected, the other end of bridge end boss fork is connected with one end of duplex fork, one end that the other end and the case end boss of duplex fork are pitched is connected, the other end of case end boss fork is connected with one end of splined sleeve flange, and the other end of splined sleeve flange is connected with one end of transmission assembly.
Preferably, a journal cross assy is provided with between described bridge end boss fork and duplex fork.
Preferably, described duplex fork and case end boss are provided with a journal cross assy between pitching.
Preferably, the outside of described journal cross assy is provided with circlip.
The utility model is a kind of engine balance forklift driving system duplex V shape drive mechanism of more reasonable structure, its structure is simple, easily manufactured, eliminate the reverse welded structure of two joint yokes used in existing engine balance forklift driving system, by existing bridge end boss fork, case end boss is pitched, convex joint yoke, recessed joint yoke, the structure of journal cross assy composition changes to a duplex fork structure, make convex, recessed universal-joint split welded structure changes to integral duplex fork, be applicable to very much the design of the driving-shaft assembly in the small space of engine balance forklift driving system, by the application of duplex V shape structure transmission shaft assembly, fork truck impact resistance is strengthened, complete machine work is more steady, manufacturing cost reduces, project organization is succinctly attractive in appearance, improve the reliability of driving system, reduce the fault rate of driving system, maintenance cost is declined to a great extent.

Detailed description of the invention
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment 1
The utility model is a kind of engine balance forklift driving system duplex V shape drive mechanism, as shown in Figure 2, is a kind of partial schematic diagram of engine balance forklift driving system duplex V shape drive mechanism.It comprises bridge end boss fork 1, journal cross assy 2, circlip 3, case end boss fork 6, duplex fork 7, front driving axle 8, bolt 9, splined sleeve flange 10 and transmission assembly 11.One end that one end and the bridge end boss of front driving axle 8 pitch 1 is locked by bolt 9 and is connected, the other end and one end of duplex fork 7 of bridge end boss fork 1 to intersect in loading journal cross assy 2 also use circlip 3 fixing and locking, duplex fork 7 other end and case end boss pitch 6 intersect load another journal cross assy 2 and with circlip 3 fixedly locked, case end boss fork 6 is locked with splined sleeve flange 10 by bolt 9 and is connected, and splined sleeve flange 10 is connected with the castellated shaft in transmission assembly 11 by female splines.Realize the connection of front driving axle 8 and transmission assembly 11, transmitting torque.
As shown in Figure 3, be the cutaway view of duplex fork structure.Duplex fork structure is pitched 6 by case end boss fork 1, journal cross assy 2, circlip 3, duplex fork 7 and case end boss and is formed.Duplex fork 7 adopts unit design, two width between centerss can be determined according to the engine balance forklift locus of different tonnage, flexible grasp, design short and sweet, due to the application of duplex V shape unit design, instead of welding of convex joint yoke and recessed joint yoke two parts, accuracy requirement and the requirement for dynamic balance of driving-shaft assembly form and position tolerance can be guaranteed, and driving-shaft assembly overbalance is the major cause of driving-shaft assembly bending vibrattion, its vibration noise caused is obvious.In addition, the end float misalignment of Hooke's joint assembly, the centering precision of junction, driving-shaft assembly two ends are also subject to the impact of overbalance precision, and the heat affecting factor etc. at a high speed during revolution during the welding of the elastic deformation of transmission shaft and convex joint yoke and recessed joint yoke two parts can change the lack of balance of driving-shaft assembly.And the lack of balance of driving-shaft assembly, cause a lot of dependent failure or abnormal damage, these problems are by the integrally-built design of duplex V shape, obtain effective solution, the fault rate of driving system obviously reduces, and duplex V shape structure design adopts solid forging blank to produce, the cancellation of welding process, processing technology simplifies greatly, and the degree of utilization of material is also fully used, and manufacture and maintenance cost decline to a great extent.
The utility model completes the moment of torsion transmission of transmission assembly 11 and front driving axle 8 in driving system by duplex fork structure.
