Technical Field
The utility model relates to a car turn to jackshaft, especially a take shock-absorbing structure turn to jackshaft.
Background
The steering intermediate shaft is used as a connecting structure of an automobile steering system, the upper end of the steering intermediate shaft is connected with an output shaft of a steering column, the lower end of the steering intermediate shaft is connected with an input shaft of a steering device, and the torque of the steering column is transmitted to the steering device, so that the automobile steering function is realized.
In recent years, the automobile industry in China is vigorously developed, and customers put forward higher requirements on automobile driving comfort. When the automobile runs on a bumpy road section and a high-frequency excitation road surface, the shock sensation can be transmitted to a steering wheel through a steering system, customer complaints are caused, and the shock can generate noise to seriously affect the driving comfort.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a still absorb the vibrations energy when effectively transmitting the steering torque to avoid the vibrations on chassis to transmit for the steering wheel, effectively promote the intermediate shaft that turns to of taking shock-absorbing structure of driver's travelling comfort.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a take shock-absorbing structure's jackshaft that turns to, it includes middle axis body, its characterized in that: be equipped with shock-absorbing structure in the one end of middle axis body, shock-absorbing structure's concrete structure is: a limiting groove is formed in the bottom of the cross joint fork, a fixing pin is assembled in the limiting groove, and the fixing pin and a limiting hole preset in the middle shaft body form interference fit; the outer ring of the cross-shaped yoke and the damping ring are in interference fit, the middle shaft body is inserted into the inner ring of the damping ring, and a limiting device is arranged at one end, close to the cross-shaped yoke, of the middle shaft body and is a limiting convex point.
As an optimized technical scheme of the utility model, the damping ring comprises three layer construction, is outer lane, rubber layer and inner circle respectively.
As a preferred technical scheme of the utility model, the fixed pin be the pin.
The outer surface of the pin may be a smooth cylindrical surface or a knurled cylindrical surface.
Compared with the prior art, the beneficial effects of the utility model are that: the complicated redundant design of common similar structure has been simplified under the prerequisite of guaranteeing function safe and reliable for essential element such as steering spindle, cross festival fork need not carry out extra redundant design again, thereby has simplified the part design, has reduced the process manufacturing cost of part simultaneously, makes whole project organization more economical and practical.

FIG. 2 is a schematic view of the assembled structure of the present invention;
fig. 3 is a sectional view of the shock absorbing structure according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Referring to the drawings, a steering intermediate shaft with a damping structure comprises an intermediate shaft body 4, wherein the damping structure is arranged at one end of the intermediate shaft body 4, and the damping structure has the following specific structure: a limiting groove 21 is formed in the bottom of the cross-shaped yoke 2, a fixing pin 1 is assembled in the limiting groove 21, and the fixing pin 1 is in interference fit with a limiting hole 41 preset in the middle shaft body 4; the outer surface of the fixing pin can be a smooth cylindrical surface or a cylindrical surface with knurling; the outer rings of the cross-shaped yoke 2 and the damping ring 3 are in interference fit, the middle shaft body is inserted into the inner ring of the damping ring 3, and a limiting device 42 is arranged at one end, close to the cross-shaped yoke, of the middle shaft body 4; the limiting device is a limiting convex point, can effectively limit the displacement distance of the middle shaft body 4 by utilizing the limiting convex point, and has simple and reasonable structure and convenient and quick processing.
As a further preferable technical solution of the present invention, the damping ring 3 is composed of three layers, which are an outer ring 31, a rubber layer 32 and an inner ring 33;
as a further preferred technical solution of the present invention, the fixing pin 1 is a pin made of a hard metal material;
during operation, the utility model discloses a turn to epaxial shock-absorbing structure principle of jackshaft and do: during normal work, the steering torque is transmitted to the damping ring 3 through the middle shaft body 4 and then transmitted to the cross yoke 2 through the damping ring 3. The existence of the rubber layer 32 on the vibration reduction ring 3 enables the whole torque transmission process to have damping characteristics, can effectively absorb vibration from the axial direction and the radial direction, and provides a vibration reduction function; when the torque is continuously increased, the deformation of the rubber layer 32 is continuously increased, so that the fixing nails 1 connected to the middle shaft body 4 gradually approach to the edge of the limiting groove 21, and finally form hard contact to transmit higher torque and play a role of radial redundancy; when the intermediate shaft body 4 is subjected to continuously increased axial tension (in the direction away from the cross-shaped yoke 2), the existence of the fixing pin 1 and the limiting groove 21 can effectively limit the intermediate shaft body 4 and the cross-shaped yoke 2 to be completely separated; when the intermediate shaft body 4 is subjected to continuously increased axial pressure, the limiting boss 42 on the intermediate shaft body 4 is gradually contacted with the end face of the inner ring 33 of the damping ring, and the inner ring of the damping ring 3 is pushed to be gradually contacted with the bottom face of the inner hole of the cross-shaped yoke 2, so that the axial pulling and pressing directions of the steering intermediate shaft body 4 have redundant functions.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
