Description

Technical Field

[0001] The utility model relates to the technical field of transmission shafts, and more specifically to a fast-installed long-slip transmission shaft. Background Art

[0002] The commonly used mechanical transmission types include belt drive, chain drive, shaft drive, gear drive and worm drive. Moreover, with the increasing social concern about global environmental issues, the requirements for emission control and improving emission of the production industry are becoming more and more stringent, and the requirements for lighter and stronger power transmission shafts are becoming higher and higher.

[0003] Generally, the transmission shaft is subject to dynamic balancing test and adjustment on a balancing machine before leaving the factory. For front-engine rear-wheel drive vehicles, it is the shaft that transmits the rotation of the transmission to the main reducer. It can be made of several sections, and the sections can be connected by universal joints.

[0004] The transmission shaft is a high-speed, less-supported rotating body, so its dynamic balance is crucial. The existing technology uses a combination of a sliding fork and a spline sleeve, but it has problems such as short stroke, difficult sealing, and slow installation.

[0005] Therefore, how to solve the problem of slow installation of the transmission shaft is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The core of the utility model is to provide a long-slip transmission shaft that can be quickly installed. The ball cage assemblies 2 at both ends use internal retaining springs, which can be quickly installed on the vehicle without the need to use bolts or other accessories to tighten them, thereby avoiding vehicle shaking caused by loose bolts during use.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 A fast-installed long-slip transmission shaft comprises a long-slip travel pipe assembly 1, both ends of the pipe assembly 1 are connected to a ball cage assembly 2, an inner retaining spring groove 3 is provided in the ball cage assembly 2, and the inner retaining spring can be used for fast loading.

[0029] The long-slip transmission shaft that is quickly installed in the above-mentioned manner uses internal retaining springs at both ends of the ball cage assemblies 2, which can be quickly installed on the vehicle without the need to use bolts or other accessories to tighten them. This can avoid the vehicle shaking caused by loose bolts during use. The ball cage assemblies 2 at both ends have preset internal retaining spring grooves 3, which can cooperate with the internal retaining springs to quickly complete the installation.

[0030] In the above embodiment, the pipe assembly 1 includes an inner spline shaft 11 and an outer spline shaft 12 that cooperate with each other. The inner spline shaft 11 is nested in the outer spline shaft 12, and the inner spline shaft 11 and the outer spline shaft 12 slide relative to each other.

[0031] It should be noted that the combined part of the inner spline shaft 11 and the outer spline shaft 12 of the pipe assembly 1 is longer. Compared with the existing combination of sliding fork and spline sleeve, the circumferential clearance is smaller after assembly under the same state, the mutual sliding stroke is long, and it can adapt to a larger swing angle. The entire shaft is splined and has good straightness.

[0032] In the above case, the cage assembly 2 is welded to the pipe assembly 1 by magnetic floating welding.

[0033] It can be understood that the ball cage assemblies 2 at both ends are welded by magnetic floating welding, which makes the welding more stable and has a longer service life.

[0034] Furthermore, a dust cover 4 is provided on the cage assembly 2 .

[0035] It should be noted that the dust cover 4 is sleeved on the ball cage assembly 2 to avoid contamination.

[0036] In the above embodiment, a telescopic sleeve 5 is provided on the pipe assembly 1 , and the telescopic sleeve 5 is fixed to the outer circumference of the pipe assembly 1 by a clamp 6 .

[0037] It can be understood that the clamp 6 fixes the two ends of the telescopic sleeve 5 to the pipe assembly 1, and the telescopic sleeve 5 will be filled with oil without leakage.

[0038] In summary, the quick-installation long-slip transmission shaft provided by the utility model has a long stroke, a small gap, is easy to install, and has a long service life through the design of the inner spline shaft 11 and the outer spline shaft 12.
