Abstract

The invention relates to an electric auxiliary steering module comprising a speed reducer, a motor, a torque sensor and a controller, wherein the speed reducer comprises a shell, a sun gear, a planetary gear set, a ring gear, a large helical gear and a drive gear shaft; the planetary gear set comprises a small helical gear and a plurality of planetary gears which are alternately and movably inserted into the small helical gear, the ring gear is sleeved and meshed with the planetary gears, each planetary gear is meshed with the sun gear and is driven by the sun gear to rotate the small helical gear, the small helical gear is meshed with the large helical gear, the drive gear shaft is axially inserted into the large helical gear and is driven by the large helical gear to steer a meshed automotive steering machine in an auxiliary mode.

Description

technical field [0001] The invention relates to an electric auxiliary steering module, in particular to a modular electric auxiliary steering device with high mechanical efficiency used in automobiles. Background technique [0002] The general electric auxiliary steering mechanism uses the speed of the vehicle and the output torque of the driver as the basis for the output of the auxiliary motor to provide power assistance for the driver when steering. At present, the conventional electric power steering devices used to combine steering shafts or racks of motor vehicles such as automobiles need to be designed in a single way according to different vehicle models and characteristic requirements, so it takes a very long design time, not only poor timeliness, but also Design costs are very high. [0003] Such as Figure 9 As shown, it is an auxiliary steering mechanism (70) of an existing gear type (pinion type), which mainly transmits the auxiliary steering force of an auxili...
