Description
Technical Field
The utility model relates to a shaft coupling combination that has buffering transmission moment of torsion that steering gear was used.
Background
The shaft coupling that uses in the present steering gear adopts solitary open shaft coupling usually, and the middle elastic component that adopts is connected and is reached the effect of transmission, but this kind of shaft coupling structure is after long-time the use, and the indentation can appear on the elastic component, takes place chap and wearing and tearing risk easily, greatly reduced the life of elastic component, influenced the performance of shaft coupling.
SUMMERY OF THE UTILITY MODEL
The utility model provides a shaft coupling combination that has buffering transmission moment of torsion that steering gear was used, it can effectively prevent the wearing and tearing that the cushion ring leads to because the deformation friction to the life of cushion ring has been prolonged.
The utility model adopts the following technical scheme: a coupler combination with a function of buffering transmission torque for a steering gear is sequentially provided with an outer coupler, a damping ring and an inner coupler from top to bottom, wherein an inner ring hole of the damping ring is sleeved outside the inner coupler and is connected with the inner coupler, an inner ring hole of the damping ring corresponds to a shaft hole of the inner coupler, the outer coupler is arranged outside the damping ring, the damping ring is embedded inside the outer coupler and is connected with the outer coupler, the damping ring is wrapped inside the outer coupler, the shaft hole of the outer coupler corresponds to the inner ring hole of the damping ring and the shaft hole of the inner coupler, the inner coupler is connected with a worm transmission shaft, and the outer coupler is connected with an output shaft of a motor.
The outer coupler is an embedded coupler. The inner coupling is an open coupling. The damping ring is arranged to be an elastic gear-shaped ring body.
The utility model discloses following beneficial effect has: after the technical scheme is used, the utility model discloses take outer shaft coupling to carry out the structure of parcel formula with the cushion ring, so not only can effectively prevent the wearing and tearing that the cushion ring leads to because of the deformation friction, thereby the life of cushion ring has been prolonged, but also can avoid leading to the condition that motor drive efficiency descends because of the elastic component fatigue damage, the output of electric steering column motor power and the security and the reliability of car steering function have been guaranteed, can also reduce the switching-over hysteresis and feel in addition, reduce steering response time and abnormal sound probability.
