As a preferred embodiment of the invention, the buffer seat is integrally formed by stainless steel.
The transmission connecting device of the hydraulic steering gear has the following advantages: during the use, after turning to the high pressure when opening in the oil circuit that turns to, high-pressure oil can partly permeate the buffering heavy groove of buffer seat, and the pressure of outside high pressure to connecting the axostylus axostyle has been alleviated greatly to the pressure in the buffering heavy groove, prevents effectively that the axostylus axostyle cylindricality from being died by the seal ring seat card of its both sides, has improved the flexibility and the reliability that the vehicle turned to greatly. In addition, utilize adjusting nut, the user can adjust the interval of buffering heavy groove and axostylus axostyle column cap according to operating condition to change the buffering pressure strain range in the buffering heavy groove, the flexibility is good. The transmission connecting device of the hydraulic steering gear is simple in structure, obvious in effect, low in cost and high in practicability.
