Abstract
The utility model relates to a steering column of an automobile, which is an energy absorbing electric steering column, and comprises a cannula and an upper tubular column, wherein a tubular column bush is arranged between the cannula and the upper tubular column. Because the tubular column bush is arranged between the cannula and the upper tubular column, when automobile collides, the steering column can absorb energy through stretching and deforming, thereby effectively reducing the impact force of a steering wheel to drivers, a whole direction system has excellent passivity safety, and supplies safest protection for the drivers during colliding.
Description
Technical field
The utility model relates to the steering column of automobile, a kind of specifically Debacle possible type electric powered steering tubing string.
Background technology
Existing electric powered steering tubular column structure as shown in Figure 1, comprise intubate 1 and last tubing string 2, intubate 1 is inserted in the tubing string 2, because every batch material shakiness of intubate 1 and last tubing string 2, cause the variation range of the power of can bursting bigger, generally, when assembly, need to improve the enjoyable amount of intubate 1 and last tubing string 2 in order to guarantee the power of to burst, therefore difficulty is big on assembly control, the range of control of the power of can bursting is bigger, along with the requirement of automotive safety function is more and more higher, can not satisfy the manned vehicle designing requirement.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming of above prior art existence, propose a kind of can be by flexible, modification energy-absorbing, effectively reduce chaufeur and be subjected to the impulsive force of bearing circle, make whole direct system have the Debacle possible type electric powered steering tubing string of fine passive security.
The technical scheme that the utility model solves above technical matters is:
Debacle possible type electric powered steering tubing string comprises intubate and last tubing string, is provided with the tubing string lining between intubate and last tubing string.
Material, the endoporus of material, excircle dimension and the last tubing string of control intubate, the pressure of control anchor point and distortion size realize the burst power of tubing string in the assembly assembling.
The utility model has the advantages that: owing between intubate and last tubing string, be provided with the tubing string lining; when collision happens; the utility model can be by flexible, modification energy-absorbing; effectively reduce chaufeur and be subjected to the impulsive force of bearing circle; thereby whole direct system has good passive satety, for chaufeur provides safest protection in collision.
Description of drawings
Fig. 1 is existing electric powered steering tubular column structure scheme drawing.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Embodiment one
The structure of present embodiment as shown in Figure 1, a kind of Debacle possible type electric powered steering tubing string comprises intubate 1 and last tubing string 2, is provided with tubing string lining 3 between intubate 1 and last tubing string 2.Tubing string lining 3 is a nyliner.
In the design, material, the endoporus of material, excircle dimension and the last tubing string 2 of control intubate 1, the pressure of control anchor point and distortion size realize the burst power of tubing string in the assembly assembling.
By endoporus dimensional control to control of the excircle dimension of intubate 1 and last tubing string 2 supports, apolegamy tubing string lining 3 (nylon spares), in the assembly assembling, the control of control assembly synthesis pressure, the burst power scope of actv. control Debacle possible type steering column, the safety of assurance steerman.
The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
Claims (2)
1. Debacle possible type electric powered steering tubing string comprises intubate and last tubing string, it is characterized in that: be provided with the tubing string lining between described intubate and last tubing string.
2. Debacle possible type electric powered steering tubing string as claimed in claim 1 is characterized in that: described tubing string lining is a nyliner.
