According to a heavy truck intelligent hybrid power steering gear with an electronic locking function, a stroke pressure relief valve mechanism of a circulating ball power steering gear is omitted, meanwhile, an electric steering gear is additionally arranged, and an input shaft 7 in the circulating ball power steering gear A and an intermediate shaft of an electric steering mechanism B are connected into a whole through a spline; power of the electric steering gear B is transmitted to the circulating ball power steering gear A through the intermediate shaft and used for steering and locking.An intermediate shaft of the electric steering mechanism is arranged in an intermediate shell, a sensor rotor is arranged on the intermediate shaft and used for detecting the steering angle and the steering torque, and the torque is transmitted to the circulating ball power steering gear A through the intermediate shaft. A stroke pressure relief valve mechanism of an original circulating ball power steering gear is omitted, meanwhile, an electric steering mechanism is additionally arranged, an electronic locking control program is additionally arranged in a controller ECU of the electric steering mechanism, and therefore a vehicle has the electronic locking function.
一种具备电子锁止功能的重卡智能混合动力转向器,循环球动力转向器取消行程卸压阀机构,同时增设一套电动转向器,循环球动力转向器A中的输入轴7与电动转向机构B的中间轴通过花键连接一体,电动转向器B的助力通过中间轴传递给循环球动力转向器A,用于转向和锁止。电动转向机构的中间轴在中间壳体内,中间轴上传感器转子,传感器用于检测转向角度和转向扭矩,通过中间轴将扭矩传递给循环球动力转向器A。本发明是将原有的循环球动力转向器部分取消行程卸压阀机构,同时增设了一电动转向机构,在电动转向机构的控制器ECU中增加了电子锁止控制程序,使车辆具有电子锁止功能。
