Abstract
The utility model relates to a transmission shaft allowing the length to be adjustable, and aims to provide a transmission shaft which is simple in structure, convenient to install and maintain, and strong in universality, and allows the installation separation distance and the length to be adjustable. According to the technical scheme, the transmission shaft allowing the length to be adjustable comprises a middle connection fork and flange forks connected to the two ends of the middle connection fork through cross shafts, and the middle portion of the middle connection fork is a hollow round pipe or a solid cylinder. The transmission shaft allowing the length to be adjustable is characterized in that the middle portion of the middle connection fork is composed of two sections which are connected into a whole through meshing of an outer spline and an inner spline. The transmission shaft allowing the length to be adjustable is suitable for the construction machinery industry.
Description
Technical field
The utility model relates to a kind of vehicular transmission shaft, the transmission shaft of the adjustable length that especially a kind of fork truck is used.Be applicable to construction machinery industry.
Background technique
Transmission shaft is the parts that connect vehicle gear box and ransaxle, is the bridge of transmission of power.The transmission shaft that extensively adopts in the fork truck prior art can't be regulated two distances between the attachment face, as shown in Figure 1 and Figure 2, middle clevis 1 ' two ends are by cross axle 2 ' flange connector fork 3 ', and middle clevis 1 ' is structure as a whole, and can not regulate himself length.So the vehicle of different model need be selected the transmission shaft of corresponding length when the different motor of assembling, gearbox.Yet the integrating error owing to reasons such as vehicle component processing, installation produce make that also the installing space of same model vehicular transmission shaft is different in size.So its versatility of existing transmission shaft is poor, the management trouble.
Summary of the invention
The technical problems to be solved in the utility model is: at the problem of above-mentioned existence, provide that a kind of simple in structure, installation and maintenance is convenient, highly versatile, the transmission shaft of the adjustable adjustable length of installing space.
The technological scheme that the utility model adopts is: a kind of transmission shaft of adjustable length, comprise middle clevis and the flange yoke that is connected middle clevis two ends by cross axle, the intermediate portion of this centre clevis is hollow circular-tube or solid cylinder, it is characterized in that: the intermediate portion of clevis is meshing with each other by external splines and internal spline by two-section and connects into integral body in the middle of described.
The intermediate portion of clevis is shaped on half of internal spline, is equipped with dust cover in its end in the middle of described.
The beneficial effects of the utility model are: the utility model is simple in structure, installation and maintenance makes things convenient for highly versatile, but the propeller shaft length free adjustment, highly versatile, convenient management.

Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the left view of prior art.
Fig. 3, Fig. 4 are structural representation of the present utility model.
Fig. 5 is the structural representation of clevis outer spline section in the middle of the utility model.
Fig. 6 is the structural representation of clevis internal spline section in the middle of the utility model.
Embodiment
As shown in Figure 3, Figure 4, present embodiment is the transmission shaft that a kind of fork truck is used adjustable length, clevis 1, cross axle 2 and flange yoke 3 in the middle of this transmission shaft comprises, and middle clevis 1 two ends are through cross axle 2 flange connectors fork 3.Middle clevis 1 intermediate portion of this example is divided into two-section, wherein one be truncated into solid cylinder and be shaped on the external splines (see figure 5) at external cylindrical surface, another is truncated into hollow circular-tube and is shaped on the internal spline (see figure 6) at inner tubal wall, and described two-section is by external splines and the internal spline structure that links into an integrated entity that is meshing with each other.Therefore, this routine propeller shaft length can be regulated by the mesh degree of regulating inside and outside spline.In order to prevent dirt accumulation at the engagement position, at the equipped dust cover 4 in the end that is shaped on this half of middle clevis of internal spline.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model also is not limited to above-mentioned giving an example; those skilled in the art; the variation of in scope of the present utility model, making; as the middle clevis that is shaped on this one side of something of external splines also can be hollow circular-tube, all should belong to protection domain of the present utility model.
Claims (2)
1. the transmission shaft of an adjustable length, comprise middle clevis (1) and the flange yoke (3) that is connected middle clevis two ends by cross axle (2), the intermediate portion of this centre clevis (1) is hollow circular-tube or solid cylinder, it is characterized in that: the intermediate portion of clevis (1) is meshing with each other by external splines and internal spline by two-section and connects into integral body in the middle of described.
