Abstract
The utility model provides a transmission shaft, including the seam of honeysuckle key yoke, the seam of honeysuckle key yoke be " worker " style of calligraphy structure, and both sides in the seam of honeysuckle key yoke are do not located to two cross axle overall compositions, and the cross axle assembly of one side is connected to the flange yoke, the cross axle assembly of the fork body end connection opposite side of spline yoke, the spline axle head connection spline housing flange of spline yoke. The spline yoke therefrom cuts within a definite time and is divided into fork somatic part and spline axial region, and the seam of honeysuckle key yoke is formed by the seam of two fork somatic part symmetries, need not use new mould. The device provided by the utility model having overcome the not enough of prior art, having need not to drop into under the prerequisite of new mould expense, arranged the position through changing cross axle and spline, the spline length of action that has extended has improved transmission shaft's the reliability and the security of whole car.
Description
Technical field
The utility model relates to a kind of transmission shaft structure, belongs to art drive systems field.
Background technique
At present, wheel loader on market is in order to increase the load of tumbling of complete machine, make complete machine operationally stability and safety more, usual employing extension shaft distance, or motor is become (torque-converters and gearbox) arrange rearward as far as possible with two, move after making the center of gravity of car load, play the object increasing load of tumbling.
In order to take into account the passing ability of car load, when many employings keep car load wheelbase constant usually, by the scheme that motor and two change are arranged rearward.Just relatively rearward, full load is also just safer for the center of gravity of such complete machine.But the rear propeller shaft length dimension between this scheme gearbox and back axle is too short, now transmission shaft structure as shown in Figure 1, spline is arranged in the middle of transmission shaft, cross axle is arranged in two ends, spline housing fork 3 and slip shaft yoke 4 are arranged on the cross assembly 2 at two ends respectively, a cross assembly 2 is connected with flange 1, another cross assembly 2 is connected with flange yoke 7, and by spline engagement between spline housing fork 3 and slip shaft yoke 4, in Fig. 1, A place is spline engagement place.In order to the matching requirements that satisfied routine is tied, just need to sacrifice spline engagement size, this is extremely disadvantageous to the reliability of transmission shaft and the Security of car load.
Model utility content
The technical problems to be solved in the utility model is when load tumbled by the scheme increase wheel loader adopting motor and two change to arrange rearward, how to ensure the reliability of transmission shaft and the Security of car load.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of transmission shaft, comprise cross assembly, slip shaft yoke, it is characterized in that: also comprise two slip shaft yoke seam, two slip shaft yoke seam is " work " font structure, two described cross assemblys are located at both sides in two slip shaft yoke seam respectively, flange yoke connects the described cross assembly of side, the fork body end of described slip shaft yoke connects the described cross assembly of opposite side, and the spline axle head of described slip shaft yoke connects spline housing flange.
Preferably, described slip shaft yoke is divided into fork body and spline shaft from centre cutting, and described pair of slip shaft yoke seam is formed by two symmetrical seam of fork body.
Preferably, the described pair of slip shaft yoke seam is provided with the mounting hole of described cross assembly.
Spline is arranged in transmission shaft one end by the transmission shaft that the utility model provides, cross axle is arranged in the middle of transmission shaft, splined shaft enters in the spline housing flange of wherein one end, thus maximally utilise space, can significantly lengthen spline engagement length, make transmission reliably safer.Two slip shaft yoke seam is formed by two symmetrical seam of fork body of two slip shaft yokes from the rear gained of middle part cutting, does not need to use new die.
The device that the utility model provides overcomes the deficiencies in the prior art, under the prerequisite without the need to dropping into new die expense, by changing cross axle and spline position, increasing spline engagement length, improve the reliability of transmission shaft and the Security of car load.

Embodiment
For making the utility model become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The transmission shaft structure schematic diagram that Fig. 2 provides for the utility model, described transmission shaft is made up of spline housing flange 5, slip shaft yoke 4, cross assembly 2, two slip shaft yoke seam 6 and flange yoke 7 etc.Two slip shaft yoke seam 6 is " work " font structure, two cross assemblys 2 are arranged on both sides in two slip shaft yoke seam 6 respectively, flange yoke 7 connects the cross assembly 2 of side, the fork body end of slip shaft yoke 4 is arranged on the cross assembly 2 of opposite side, the spline axle head of slip shaft yoke 4 is inserted in spline housing flange 5, and in Fig. 2, B place is spline engagement place.
The transmission shaft that the utility model provides no longer adopts the structure that spline is arranged in the middle of transmission shaft, cross axle is arranged in two ends, but spline is arranged in transmission shaft one end, cross axle is arranged in the middle of transmission shaft, splined shaft is inserted in the spline housing flange of wherein one end, so just space is maximally utilised, can significantly lengthen spline engagement length, make transmission reliably safer.
Two slip shaft yoke seam 6 is formed by two symmetrical seam of fork body of two slip shaft yokes 4 from the gained after the cutting of middle part, does not need to use new die.The structure of slip shaft yoke 4 as shown in Figure 3 and Figure 4, two castings slip shaft yoke 4 is out cut from centre, be divided into fork body 4-1 and spline shaft 4-2, as shown in Figure 5, milling truncation face can be selected according to equipment and required precision, then by two fork body 4-1 to welded together, form " work " font structure, then process cross axle mounting hole, thus obtain two slip shaft yoke seam 6, as shown in Figure 6.
Each assembling parts directly with bar processing, then just can be obtained the transmission shaft structure that the spline shown in Fig. 2 is arranged in one end, cross axle is arranged in centre by spline housing flange 5.
As shown in Figure 1, assuming that in limited length of installation L, the length of action of mould restriction spline is the longest is a; If when gearbox output torque reaches certain value, according to the content about contact strength of tooth surface computational methods in " GB/T17855-1999 spline bearing capacity computational methods ", calculate that conventional spline is arranged in the middle of transmission shaft, cross axle is arranged in the transmission shaft structure at two ends, spline engagement does not meet contact strength of tooth surface requirement when being of a size of a, the easy conquassation of spline.
Composition graphs 2, when the spline adopting the utility model to provide is arranged in transmission shaft one end, cross axle is arranged in the transmission shaft structure in the middle of transmission shaft, effectively can lengthen the length of action of spline, reach b (b > > a), meet contact strength of tooth surface requirement, ensure that the reliability of transmission shaft and the Security of car load.
The utility model, under the prerequisite not dropping into new die expense, by changing cross axle and spline position, increasing spline engagement length, improve the reliability of transmission shaft.
