The invention discloses an automotive column type electric power steering system, comprising a steering column and a power steering system. The power steering system comprises a motor, a planetary gear reducer, a synchronous belt, a torque / angle sensor, a controller and a shell. Torque is amplified through the planetary gear reducer, input torque is low, output torque is high, transmission efficiency is increased significantly, steering operation of automobiles is more flexible and easier, safety is better, and active return of the steering mechanism can be realized; through connection with the synchronous belt, the problem of abnormal noise during use of the column type electric power steering system in the past is solved effectively; the motor is parallel to the steering column, so that the whole power steering sub-system is small in size, interference is avoided, and installation, detachment and replacement are facilitated; the planetary gear reducer is parallel to the steering column and is installed at the same position as an output shaft in the conventional steering column, so that the existing steering column can be replaced directly without modifying other parts of the automobiles.
Description
technical field [0001] The invention relates to the technical field of automobile engineering, in particular to an automobile column type electric power steering system. Background technique [0002] At present, most of the electric power steering systems used in various automobiles are realized by installing a worm gear reducer on the steering column. With the development of the times and technological progress, the following problems have gradually been exposed: the transmission ratio of the worm gear reducer transmission mechanism Small size and low transmission efficiency; when installing the booster motor, the output shaft of the booster motor needs to be installed on the side of the steering column perpendicular to the steering column, which occupies a large space in the cab. Due to the compact space of the vehicle cab, the existing The worm gear and worm electric steering column often interferes during assembly, which increases the labor intensity of the operator; and...
