Problems solved by technology

[0002] At present, the electric power steering system used in various vehicles is mostly realized by installing a worm gear reduction device on the steering column. This type of structure is limited by its own size, the transmission ratio is relatively low, and the transmission efficiency is low, which directly affects the output torque. the size of
Since it needs to be installed on the side of the steering column together with the external motor, it takes up a lot of space. Since there are various assemblies and components distributed under the vehicle instrument panel, the steering column and peripheral components of the existing vehicle are assembled and maintained. Frequent interference, difficult installation and removal operations

Abstract

The invention discloses a compact steering column type automobile electric power booster, which comprises a casing, a planetary gear reducer is installed at one end of the casing, a transverse partition is arranged in the casing, and a hollow space is installed in the casing between the transverse partition and the planetary gear reducer. Type inner rotor brushless motor, the coil stator of the hollow inner rotor brushless motor is connected with the inner wall of the shell, the inner hole of the magnetic steel rotor center of the hollow inner rotor brushless motor is provided with a shaft sleeve, and the shaft sleeve is fixedly installed on the sleeve shaft , one end of the sleeve shaft is connected with the diaphragm of the casing through the first positioning bearing. The hollow inner rotor brushless motor and the planetary gear reducer are arranged coaxially with the steering column, occupying a small space and will not interfere with the surrounding components, easy to arrange on the car, and easy to disassemble and install.

Description

technical field [0001] The invention relates to an automobile steering device, in particular to a compact steering column type automobile electric booster. Background technique [0002] At present, the electric power steering system used in various vehicles is mostly realized by installing a worm gear reduction device on the steering column. This type of structure is limited by its own size, the transmission ratio is relatively low, and the transmission efficiency is low, which directly affects the output torque. the size of. Since it needs to be installed on the side of the steering column together with the external motor, it takes up a lot of space. Since there are various assemblies and components distributed under the vehicle instrument panel, the steering column and peripheral components of the existing vehicle are assembled and maintained. Interference occurs frequently, and installation and removal operations are difficult. Contents of the invention [0003] The p...
