Abstract
The utility model discloses a blank structure of an automotive steering intermediate shaft yoke. The technical scheme is that the blank structure of the automotive steering intermediate shaft yoke comprises an intermediate shaft yoke body, an opening is formed in the hole wall of the intermediate shaft yoke body and is communicated with a hole, a connector is arranged between two side walls of the opening, the connector is opposite to a fastening screw hole of a finished intermediate shaft yoke, and the radial size of the connector is less than or equal to the diameter of the bottom hole of the fastening screw hole. The intermediate shaft yoke body is made from nodular cast iron. The bank structure of the automotive steering intermediate shaft yoke is suitable for an automotive steering system.
Description
Technical field:
The utility model relates to a kind of automobile steering system, particularly joint fork blahk structure in the middle of a kind of motor turning.
Background technology:
Existing common steering intermediate shaft joint fork blank is forging blank, after to the processing of blank axis hole, in order to obtain bolt needed elastic deformation gripping power when fastening, need to process port at hole wall and outer projection thereof.The shortcoming that this forging blank structure is brought is need to increase in addition grooving mouth operation, the cost increase.
Summary of the invention:
Joint was pitched blahk structure in the middle of the purpose of this utility model provided a kind of motor turning that a kind of machining property is good, cost is low.The technical scheme that realizes the utility model purpose is, joint fork blahk structure in the middle of a kind of motor turning, joint fork body in the middle of comprising, it is characterized in that: have flatly on the hole wall of described middle nodal axisn joint fork axon to be communicated with the hole, between the two side of this mouthful, be provided with connector, this connector is relative with joint fork fastening bolt holes in the middle of the finished product, and the radial dimension of this connector is less than or equal to the bottom diameter of above-mentioned fastening bolt holes.The material of joint fork body is spheroidal graphite iron in the middle of described.
The utility model has advantages of that compared with the prior art good manufacturability, cost are low.
Description of drawings:
Fig. 1 is front view of the present utility model, and Fig. 2 is the left view of Fig. 1, and Fig. 3 is cast blank through the joint of the steering intermediate shaft after processing fork structural representation, and Fig. 4 is the A-A cutaway view of Fig. 3.
The specific embodiment:
The utility model adopts foundry technique to make the middle joint fork blank of hole wall opening, this blank has been saved the manufacturing procedure at the hole wall upper cut, produce the undesirable problem of shape that distortion causes the hole that processes because of hole wall opening 1 man-hour in order to overcome axis hole is added, between the two sides of this mouthful, leave one and connect cylinder 2, it is relative with bolt hole 3 on the sidewall that this connects cylinder, its diameter should be less than or equal to the bottom diameter of bolt hole, make this connect cylinder processed elimination when the processing bolt hole, in order to improve the processing characteristics of tween drive shaft, adopt the spheroidal graphite iron material.
Claims (2)
1. the middle joint of motor turning is pitched blahk structure, joint fork body in the middle of comprising, it is characterized in that: have flatly on the hole wall of described middle nodal axisn joint fork axon to be communicated with the hole, between the two side of this mouthful, be provided with connector, this connector is relative with joint fork fastening bolt holes in the middle of the finished product, and the radial dimension of this connector is less than or equal to the bottom diameter of above-mentioned fastening bolt holes.
2. joint is pitched blahk structure in the middle of a kind of motor turning as claimed in claim 1, it is characterized in that: the material of joint fork body is spheroidal graphite iron in the middle of described.
