摘要： A steering system includes: a steering shaft to which a steering member is coupled; a worm wheel attached to the steering shaft so as to be rotatable integrally with the steering shaft; a housing that houses the worm wheel; an output shaft that is coaxial with the steering shaft and rotatable relative to the steering shaft and coupled to a steering operation mechanism; and a clutch mechanism that enables and disables transmission of power between the steering shaft and the output shaft. The clutch mechanism is housed and disposed in an internal space in the housing. A solenoid in the clutch mechanism is disposed on the opposite side of the worm wheel in an axial direction from a mechanical portion of the clutch mechanism.

摘要： A gearbox assembly for an electric power steering apparatus comprises an input shaft which carries a worm gear and is supported relative to the housing at one end by a first bearing assembly and at the other by a second bearing assembly, an output shaft which carries a wheel gear which is fixed relative to a housing and which meshes with a worm gear on the input shaft, and a spring assembly which acts between the housing and the first bearing assembly, and the spring assembly applying a biasing force onto the second bearing in a first direction away from the neutral position so as to ensure that the worm and wheel are fully engaged. The spring assembly has a spring rate which has a step change about the neutral position such that the rate of change in the force exerted by the spring assembly on the second bearing assembly as the spring moves in the first direction from its neutral position is lower than the rate of change in the force as the spring moves in the second direction away from the neutral position.

摘要： A bearing bushing, comprising: a bushing body and a buffer member fixed therein. The buffer member comprising a spring piece. The spring piece is provided on the top of the bushing body, and comprises an extending part and a fixed part. The extending part obliquely extends downward from two opposite sides of the fixed part. The bearing bushing provides a special preload force for the deformation of the fixed part by means of the extending part of the spring piece so as to enhance the robustness of the preload design, reduce the friction torque, and reduce the engaging noise of the worm gear and the worm in different working situations. Also disclosed are a preload structure, a housing of a transmission mechanism, and an assembling structure of a worm gear and a worm.

摘要： A gear isolator assembly includes a gearbox housing (101), a first gear (102) having a first axis of rotation about a first shaft (114) and the second gear (104) having a second axis of rotation about a second shaft (109). The first (102) and second gears (104) are rotatably mounted in a gearbox housing (101) so that the first (102) and second gears (104) mesh with each other such that the first axis of the first gear (102) is substantially perpendicular to the second axis of the second gear (104). The gear isolator assembly is preferably disposed within the gearbox housing (101) about the second gear (104) for reducing noise generated between the first (102) and second gears (104) during operation of the mechanism (100).
