Abstract
The invention discloses a transmission shaft, which is characterized by comprising an inner shaft pipe, an outer shaft pipe and pressed-in rubber, wherein the pressed-in rubber is vulcanized on the outer surface of the inner shaft pipe, and the inner shaft pipe of the vulcanized pressed-in rubber is pressed into the outer shaft pipe. The structure of the transmission shaft disclosed by the invention has the characteristics of skillful design, compact structure and the like, bidirectional torsional damping not only can be used for reducing impacts caused by fluctuation of engine evolution speed to a main speed reducer but also can be used for absorbing torsional fluctuations brought by the angle variation of the transmission shaft and effectively absorbing vibrations brought by high-speed autorotation; and the transmission shaft is simple in materials and good in economy, and has an overload protection function due to friction force transmission.
Description
Technical field
The invention belongs to the technical field of automobile, particularly a kind of transmission shaft with built-in rubber torsional vibration damper with transmission shaft.
Background technique
Modern Car improves the requirement of highest speed, riding comfort and NVH day by day, especially the intermediate car of rear-guard or 4 wheel driven.Vibration damping mode commonly used at present is to adopt rubber coupling, but its size is bigger, and the apron space of requirement is bigger, often causes big difficulty to layout.
Summary of the invention:
The object of the present invention is to provide a kind of transmission shaft with built-in rubber torsional vibration damper.Its major function is that transmission shaft is divided into two sections central siphons that cooperatively interact, and between two central siphons, separates with rubber, is equivalent between transmission shaft and ransaxle, add a torsional vibration damper.Like this, in transferring power, can absorb the torsional vibration of transmission shaft well.
Technological scheme of the present invention is achieved in that
Transmission shaft is characterized by: it is by interior central siphon, outer central siphon and be pressed into rubber and form, and is pressed into the outer surface of the vulcanization of rubber at interior central siphon, and the interior central siphon that sulfuration is pressed into rubber is pressed into outer central siphon.
Structure of the present invention has characteristics such as design is ingenious, compact structure; The bidirectional torsion vibration damping both can reduce because the impact that the engine speed fluctuation causes main reducing gear; Can reduce again because the vehicle wheel rotational speed fluctuation to the impact of power assembly, absorbs because the transmission shaft angle changes the fluctuation of reversing that brings simultaneously; The vibration that effective absorption self high speed rotating brings; The material of this torsional vibration damper is simple, good economy performance; Has overload protection function.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment:
Below in conjunction with accompanying drawing the present invention is done further description:
Transmission shaft is characterized by: it is by interior central siphon 2, outer central siphon 1 and be pressed into rubber 3 and form, and is pressed into the outer surface of rubber 3 sulfurations at interior central siphon 2, and the interior central siphon 2 that sulfuration is pressed into rubber 3 is pressed into outer central siphon 1.
As shown in Figure 1; Transmission shaft is mainly by interior central siphon 2, outer central siphon 1 be pressed into rubber 3 and form; In the working procedure; Outer central siphon 1 is passed to interior central siphon 2 with the friction of outer central siphon 1 with power through the rubber 3 that is pressed into that compresses, and interior central siphon 2 is passed to main reducing gear through universal joints with power, and the present invention can also be by interior central siphon 2 transferring power to outer central siphon 1.
Transmission shaft, its shape that is pressed into rubber 3 can be a ring-type.
Transmission shaft, its shape that is pressed into rubber 3 can be a strip.
Transmission shaft, its shape that is pressed into rubber 3 can be a helical.
Transmission shaft can be used as intermediate propeller shaft, also can be used as main drive shaft.
The present invention can be applied to automobile, also can be applied to other equipments such as engineering machinery.
