When the impact plate is impacted, the spring body has certain buffer effect and absorbs certain impact force.
Preferably, the two ends of the first seamless steel tube body are both provided with connecting plates, and the two ends of the first seamless steel tube body are both fixedly connected with the second seamless steel tube body through the connecting plates.
Preferably, the outer diameter of the second seamless steel pipe body is smaller than the inner diameter of the first seamless steel pipe body. The first impact plate is impacted firstly, the first impact plate is elastically connected with the first seamless steel tube body, a certain buffering effect is achieved, if the impact force is large, the first seamless steel tube body bears the impact force of the rest part, and the outer diameter of the second seamless steel tube body is smaller than the inner diameter of the first seamless steel tube body, so that a gap exists between the first seamless steel tube body and the second seamless steel tube body, a certain deformation space is provided for the first seamless steel tube body, and the second seamless steel tube body is prevented from being extruded to deform.
Preferably, a sponge cushion is arranged on the outer surface of the first seamless steel pipe body, a plurality of through holes matched with the spring body are formed in the sponge cushion, one end of the spring body is fixedly connected with the impact plate, and the other end of the spring body penetrates through the through holes and is fixedly connected with the first seamless steel pipe body. When the impact plate receives the impact, the sponge cushion and the spring body simultaneously generate reaction force to offset the impact force of the upper part of the impact plate, the buffering effect is improved, the reduced impact force is borne by the first seamless steel tube body, and when the steering shaft is prevented from receiving large impact, the second seamless steel tube body is deformed, so that the sensitivity of the steering wheel is ensured, and the safe driving of a driver is facilitated.
The utility model has the advantages that: the automobile steering shaft is not easy to bend when being subjected to huge impact; safe and reliable, reasonable in design.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a cross-sectional view a-a of fig. 1.
In the figure: 1. the seamless steel pipe comprises a first seamless steel pipe body, a second seamless steel pipe body, a U-shaped fork, 4 connecting blocks, 5 connecting plates, 6 impact plates, 7 spring bodies, 8 sponge pads and 9 through holes.
Detailed Description
The invention is further described with reference to the accompanying drawings and the detailed description.
In the embodiment shown in fig. 1, a round hot-rolled seamless steel tube for a vehicle comprises a first seamless steel tube body 1, a second seamless steel tube body 2, a U-shaped fork 3 and a connecting block 4, wherein the second seamless steel tube body 2 is positioned in the first seamless steel tube body 1, one end of the second seamless steel tube body 2 penetrates through one end of the first seamless steel tube body 1 and is fixedly connected with the U-shaped fork 3, the other end of the second seamless steel tube body 2 penetrates through the other end of the first seamless steel tube body 1 and is fixedly connected with the connecting block 4, and two ends of the first seamless steel tube body 1 are fixedly connected with the second seamless steel tube body 2.
