Up to the present the car drive shaft assembly all is to be provided with the axostylus axostyle that connects universal joint in the middle of adopting the two ends universal joint, this design has just been considered the usability of live axle, and to material-saving joint consumption, it is thorough that the maintenance and installation aspect is not considered, in the process that drives, needed to turn to effect owing to be in the universal joint (being the fixed end universal joint) of road wheel end, and the universal joint (being slippage end universal joint) that is in the gearbox end just just produces slippage under the situation of Uneven road, and the slippage scope is very little, so the wearing and tearing of road wheel end universal joint are big, life-span is low, be the parts that needs are often changed, whenever change three road wheel end universal joints according to statistics and just need change a gearbox end universal joint, again load onto car again and whenever tear next universal joint open, the maintenance step is more loaded down with trivial details usually, need more than 60 minutes, the cost of labor of often changing a road wheel end universal joint in some American-European countries is more taller than newly buying a new live axle, so how to dismantle the key that drive shaft assembly becomes problem fast.
Summary of the invention
But the drive shaft assembly that the purpose of this invention is to provide a kind of conveniently fast disassembling.
Purpose of the present invention is achieved through the following technical solutions: but a kind of drive shaft assembly of conveniently fast disassembling, include jack shaft, be arranged on the fixed end universal joint and the slippage end universal joint that is arranged on the jack shaft the other end of jack shaft one end, be characterized in: described jack shaft is divided into left and right half, removably connects by joiner between the left and right half.
The present invention further is set to: described joiner includes left and right tie-plate, and wherein, left tie-plate is fixedlyed connected with left half axle, and right tie-plate is fixedlyed connected with right axle shaft, and left and right tie-plate connects by screw.
The present invention further is set to again: described left tie-plate is provided with spline, and the corresponding spline that is provided with on the end of left half axle, and be provided with draw-in groove near exterior edge face place at spline, spline housing are located in the spline and with the jump ring location of end; Also be provided with spline on the described right tie-plate, the corresponding spline that is provided with on the end of right axle shaft, and be provided with draw-in groove near exterior edge face place at spline, spline housing are located in the spline and with the jump ring location of end.
Further, described screw is that eight circumference uniform distributions connect left and right land on left and right tie-plate.
Further, described joiner is arranged on a side of the close fixed end universal joint of jack shaft.
Further: the distance of the exterior edge face of described joiner and fixed end universal joint is 213mm-217mm.
The invention has the beneficial effects as follows: by jack shaft being divided into the left and right half that removably connects, thereby when the fixed end universal joint damages, can dismantle the semiaxis and the universal joint that are connected and fixed the end universal joint easily changes, changed people's need under car load, change the fixed end universal joint or whole drive shaft assembly disassembled and change inconvenience that the fixed end universal joint brought and uneconomical more all the time, greatly improved time efficiency and reduced time cost.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention
Fig. 2 is the A-A sectional drawing of Fig. 1
Embodiment
Now in conjunction with the accompanying drawings the present invention is further described:
As shown in Figure 1 and Figure 2, but the embodiment of the drive shaft assembly of a kind of conveniently fast disassembling of the present invention, include jack shaft 2, be arranged on the fixed end universal joint 1 and the slippage end universal joint 3 that is arranged on jack shaft 2 the other ends of jack shaft 2 one ends, described jack shaft 2 is divided into left and right half 21,22, removably connects by joiner 23 between the left and right half 21,22.By jack shaft 2 being divided into the left and right half 21,22 that removably connects, thereby when fixed end universal joint 1 damages, can dismantle the semiaxis 21 and the universal joint 1 that are connected and fixed end universal joint 1 easily changes, changed people's need under car load, change the fixed end universal joint or whole drive shaft assembly disassembled and change inconvenience that the fixed end universal joint brought and uneconomical more all the time, greatly improved time efficiency and reduced time cost.
Joiner can have various structures, such as the n type joiner that adopts opening, when being set in a left side, during the two ends of right axle shaft, tighten up with screw at opening end and to realize the purpose that removably connects, what but present embodiment adopted is: joiner 23 includes a left side, right tie-plate 231,232, wherein, left side tie-plate 231 is fixedlyed connected with left half axle 21, right tie-plate 232 is fixedlyed connected with right axle shaft 22, a left side, right tie-plate 231,232 by screw 233 connections, in the diagram, described screw 233 is that eight circumference uniform distributions are on a left side, right tie-plate 231, connect a left side on 232, right land 231,232.Adopt the mode of present embodiment, it is reliable that the applicant thinks that it connects, and operation is also convenient, but the present invention does not get rid of the joiner that adopts other structure.
In the diagram, described left tie-plate 231 is provided with spline 2311, and the corresponding spline 211 that is provided with on the end of left half axle 21, and be provided with draw-in groove near the place, exterior edge faces at spline 211, spline 211 are set in the spline 2311 and with jump rings 234 location of end; Also be provided with spline 2321 on the described right tie-plate 232, the corresponding spline 221 that is provided with on the end of right axle shaft 22, and be provided with draw-in groove near the place, exterior edge faces at spline 221, spline housing 221 are located in the spline 2321 and with jump rings 24 location of end.Tie-plate and semiaxis pass through splined; its coupling reliability is good; it is also convenient to install; but such as the mode that adopts the square shaft square hole to add to lock screw (as the tie-plate upper aperture; the end of semiaxis is set as square shaft is set in the square hole, and then realize locking perpendicular to axis one lock screw being set on the tie-plate) or other connecting mode also still all within protection domain of the present invention.
