The technical field is as follows:
the invention relates to a steering transmission shaft capable of avoiding torque fluctuation, and belongs to the technical field of automobile steering systems.
Background art:
the existing automobile steering transmission shaft has the following functions: the steering transmission shaft is a bridge for connecting a steering column and a steering engine, is a key part for transmitting force and absorbing external unfavorable excitation, and most of automobile steering transmission shafts are in an upper and lower cross joint fork structure form. For the front axle with heavy load, the above process is not always satisfactory, and a ball steel ball type shaft type steering transmission shaft is required to provide high torque.
The existing steering transmission shaft uses a universal joint in a cross shaft joint fork form, and because of the unequal speed of a cross shaft, the moment fluctuation of a steering system exists, the steering shaking and the steering force are influenced to a certain extent, and thus the control stability and the safety of the whole vehicle are influenced.
Therefore, there is a need to improve the prior art to overcome the deficiencies of the prior art.
The invention content is as follows:
the invention provides a steering transmission shaft capable of avoiding torque fluctuation in order to solve the problems in the prior art.
The technical scheme adopted by the invention is as follows: the utility model provides a can avoid moment fluctuation steering drive shaft, includes hemisphere casing, big clamp, dust cover, ball steel ball formula axostylus axostyle, little clamp, steel ball, holder, little steel ball, jump ring and interior star gear, the steel ball is located the holder, and interior star gear is located the hemisphere casing, and the both ends of ball steel ball formula axostylus axostyle are equipped with the external splines that cooperate and be used for the transmission moment of torsion with the internal spline of interior star gear, be equipped with the jump ring groove between the external splines at ball steel ball formula axostylus axostyle both ends and the internal spline of interior star gear, the jump ring is installed in the jump ring groove, hemisphere casing and dust cover link together through big clamp, and dust cover and.
Furthermore, a retainer is also arranged in the ball steel ball type shaft rod, and the small steel balls are positioned in the retainer.
The invention has the following beneficial effects: the torque fluctuation steering transmission shaft can avoid the influence of the steering torque fluctuation on the steering stability of the whole vehicle, has far-reaching significance on safe driving of the whole vehicle, and can improve the comfort of the whole vehicle. In addition, the invention can provide large torque by using the ball steel ball type shaft rod, and has the advantages of smooth sliding, small meshing clearance and the like.
