Abstract
The invention discloses dismounting tool for a transmission shaft of an automobile. The tool is formed by a shifting fork (1), a pull rod (2) and a pull ring (3), wherein the middle of the shifting fork (1) is fixed with the front end of the pull rod (2), a plane which the shifting fork (1) is arranged on is perpendicular to the axis of the pull rod (2), the rear end of the pull rod (2) is fixed on an outer ring of the pull ring (3), and the axis of the pull rod (2) is in the same plane which the pull ring (3) is arranged on. The dismounting tool for the transmission shaft of the automobile can simplify dismounting operation of the transmission shaft, and not only saves time and labor, but also can prevent a seal element of the transmission shaft and a casing of the transmission box from being damaged. The dismounting tool has the advantages of being ingenious in design, simple in structure, convenient and fast to operate and the like, and is suitable for dismounting of transmission shafts of multiple automobile models.
Description
Technical field
The invention belongs to technical field of tooling clamps, specifically, the particularly disassembling fixture of truck drive shaft.
Background technology
Power transmission shaft is the vitals of automobile transferring power, is arranged between gearbox and the differential mechanism.One end of power transmission shaft is connected with differential mechanism, and the other end is connected with gearbox, and is located by jump ring.When needs dismountings power transmission shaft, existing way is: insert gap between power transmission shaft and the gearbox with crowbar first, then take the lower end of crowbar as fulcrum prizes power transmission shaft, the elastic force that makes power transmission shaft overcome jump ring is extracted from gearbox.Because the narrow space between power transmission shaft and the gearbox adopts the crowbar disassembling section inconvenient, not only workman's labour intensity is large, and the efficient of dismounting is lower.Simultaneously, crowbar in prizing the process of power transmission shaft, the housing of easy damaged gearbox on the one hand; On the other hand, stressed transmission shaft is uneven, very easily damages the seal of power transmission shaft, and seal can not be reused.
Summary of the invention
It is a kind of easy to operate that technical problem to be solved by this invention is to provide, and can not cause the truck drive shaft disassembling fixture of gear box casing and seal damage.
Technical scheme of the present invention is as follows: a kind of truck drive shaft disassembling fixture, consisted of by shift fork (1), pull bar (2) and draw ring (3), wherein, the front end of the middle part of fork (1) and pull bar (2) fixes, the plane at this shift fork (1) place and the axial line of pull bar (2) are perpendicular, the rear end of pull bar (2) is fixed on the outer ring of draw ring (3), and the axial line of the plane at draw ring (3) place and pull bar (2) at grade.
When the present invention is used for the dismounting power transmission shaft, snap in junction between power transmission shaft and the gearbox with shift fork first, make shift fork spacing by the step surface that carries on the power transmission shaft, and pull bar parallels with power transmission shaft, then pass the inner ring of draw ring with crowbar, then take the lower end of crowbar as fulcrum prizes draw ring backward, make shift fork apply backward pulling capacity to power transmission shaft, power transmission shaft overcomes the elastic force of jump ring and extracts from gearbox.Because the contact area between shift fork and the power transmission shaft is large, and the impetus of crowbar is on gearbox, and the one side process that prizes crowbar can not damaged the housing of gearbox like this; On the other hand, prize operation and be not subjected to spatial constraints, very simple and convenient, can effectively reduce workman's labour intensity, greatly improved the efficient of dismounting.Simultaneously, the suffered pulling capacity of power transmission shaft is on its axial line, and stressed transmission shaft is even, can prevent that the seal of power transmission shaft is damaged, thereby has guaranteed that seal can reuse.
Described shift fork (1) is circular arc, moulding simple rule so on the one hand, and processing and fabricating is easy, and cost is low; On the other hand, shift fork is combined with power transmission shaft closely, can increase as much as possible the contact area of shift fork and power transmission shaft, thereby has further improved the reliability of disassembling section.
Described pull bar (2) is comprised of backstay (2a), positioning pipe (2b) and nut (2c), the rear end of described backstay (2a) and draw ring (3) fix, the front end of backstay (2a) stretches into the rear end of positioning pipe (2b), both threaded engagement, by nut (2c) locking, the front end of described positioning pipe (2b) is fixed on the fork (1).Above structure is unclamped nut can be made between backstay and the positioning pipe and relatively rotate, thereby adjusts the length of pull bar, to adapt to the needs of different automobile types dismounting power transmission shaft; After the pull bar length adjustment was good, fastening nut got final product again, and Adjustment operation is not only convenient but also quick.
Beneficial effect: the present invention can simplify the disassembling section of power transmission shaft, not only time saving and energy saving, and can prevent that the seal of power transmission shaft and the housing of gearbox are damaged, and have the characteristics such as design is ingenious, simple in structure, simple operation, all applicable for the power transmission shaft dismounting of various.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is use state diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, present embodiment is made of shift fork 1, pull bar 2 and draw ring 3.Wherein, shift fork 1 is circular arc, and the plane at shift fork 1 place and the axial line of pull bar 2 are perpendicular, and the plane at the axial line of pull bar 2 and draw ring 3 places at grade, and draw ring 3 is circular ring structure.Described pull bar 2 is comprised of backstay 2a, positioning pipe 2b and nut 2c, and the axial line of the axial line of backstay 2a and positioning pipe 2b point-blank.The outer ring of the rear end of described backstay 2a and draw ring 3 fixes, and the extended line of backstay 2a is by the center of circle of draw ring 3.The front end of described backstay 2a stretches into the rear end of positioning pipe 2b, and by threaded engagement, by nut 2c locking, this nut 2c is sleeved on the backstay 2a, and nut 2c is close to the rear end face of positioning pipe 2c between backstay 2a and the positioning pipe 2b.The front end of described positioning pipe 2b is fixed by welding in the middle part of fork 1.
The operation principle of present embodiment is as follows:
Such as Fig. 3 and in conjunction with Fig. 1, shown in Figure 2, at first unclamp nut 2c, make between backstay 2a and the positioning pipe 2b to relatively rotate, thereby adjust the length of pull bar 2, make the length of pull bar 2 applicable mutually with the length of power transmission shaft 4 to be removed, after pull bar 2 length adjustment are good, again fastening nut 2c locking; Then snap in junction between power transmission shaft 4 and the gearbox 5 with shift fork 1, make shift fork 1 spacing by the step surface that carries on the power transmission shaft 4, and pull bar 2 parallels with power transmission shaft 4, then use crowbar (not shown in FIG.) to pass the inner ring of draw ring 3, prize backward draw ring 3 take the lower end of crowbar as fulcrum, make shift fork 1 apply backward pulling capacity to power transmission shaft 4, power transmission shaft 4 elastic force that overcomes jump ring is extracted from gearbox 5 like this.
With reference to Fig. 1, Fig. 2, in the present embodiment, pull bar 2 is circular or square straight-bar structure.All the other structures of present embodiment are identical with embodiment 1, do not do at this and give unnecessary details.
