Detailed Description
The following description briefly describes embodiments of the present invention with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work based on the embodiments of the present invention belong to the protection scope of the present invention.
Fig. 1-3 show the preferred embodiment of the present invention, the structure of which is analyzed in detail from different perspectives, respectively.
The steering gear input shaft shown in fig. 1 comprises an input shaft body 1 and an extension rod 2 detachably and fixedly connected with the input shaft body 1. When the length of an input shaft required by a vehicle type is too long, an extension bar 2 is added for length adjustment; when the required input shaft length of motorcycle type is shorter, can remove extension bar 2, directly use input shaft body 1.
The structure of the input shaft body 1 is the same as that of the existing input shaft on the market, and is not described herein. The input shaft body 1 is arranged on the steering gear body 3, and an external spline is formed on the outer wall surface of one end of the input shaft body, which is far away from the steering gear body 3.
As shown in fig. 2, the extension bar 2 includes an extension bar main body 21 and a connecting portion 22 fixedly connected to the extension bar main body 21. The end of the extension bar main body 21 away from the connecting portion 22 has the same structure as the end of the input shaft body 1 extending out of the steering gear body 3. The connecting portion 22 is a hollow structure, and an inner wall surface thereof is formed with an inner spline matched with an outer spline on an outer wall surface of the input shaft body 1. Extension bar 2 and input shaft body 1 are fixed and the endwise slip through the cooperation circumference of internal spline and external spline, through the axial position who adjusts extension bar 2 and input shaft body 1, adjustable input shaft length. In the concrete installation, can install earlier steering column and turn to the jackshaft, 2 length adjustment of extension bar go on at last to guarantee the accuracy of input shaft length adjustment. Meanwhile, other parts are firstly installed, and finally the length of the input shaft is adjusted, so that the extension rod 2 is convenient to adjust.
Specifically, as shown in fig. 3, the connecting portion 22 is a clamp provided with a strip-shaped groove 221 along the axial direction of the extension bar 2, and an adjusting device for adjusting the tightness of the clamp is arranged on the clamp, so that the extension bar 2 can be moved or fixed by adjusting the tightness of the clamp. The adjusting device comprises a bolt assembly 222 and connecting pieces 223 which are symmetrically arranged at the edges of two sides of the clamping hoop and are used for installing the bolt assembly 222 and provided with holes. The bolt assembly 222 passes through the connecting members 223, and the distance between the two connecting members 223 can be adjusted by tightening or loosening the nuts, thereby adjusting the tightness of the clamp.
When the length needs to be adjusted, the clamp is loosened through the rotating nut, the extension bar 2 axially slides along the input shaft body 1, and the length of the input shaft is adjusted; after the length reaches the expected position, the nut is rotated reversely, the hoop is locked, and the extension bar 2 and the input shaft body 1 are fixed relatively in position and have no play in the axial direction.
Specifically, the extension bar main body 21 is integrally formed with the connecting portion 22. The diameters of the extension bar main body 21 and the connecting portion 22 can be determined according to the diameters of the steering gear input shaft and the steering intermediate shaft universal joint spline in actual production.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
