摘要： A gearbox assembly for all 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： An assembly comprises a male component and a female component which connect together to form a mechanical connection, the female component being adapted to at least partially receive an end portion of the male component. The female component has at least one bore which is adapted to receive a clamping pin which can be tightened to clamp the female component around the male component. A guide is provided which is carried by the male component and which defines at least one blocking region and one opening region, the opening region being aligned with the at least one bore in the female component to permit insertion of the clamping pin into the bore when the male component and female component are correctly aligned and the blocking region otherwise preventing insertion of the clamping pin when the male component is inserted into the female component with an incorrect alignment. The guide assists in achieving correct alignment of the male and female components during assembly.

摘要： An electric power assisted steering system comprises a motor connected to a portion of a steering mechanism through a worm carried by a worm shaft and a wheel carried by an output shaft operatively coupled to the steering mechanism. The shaft is supported in at least one bearing which has some internal clearances and supports the worm shaft in such a manner that it is free to pivot through an angle in planes which include its own axis due to a degree of axial free play of the first bearing assembly. The bearing assembly comprises an inner race having a groove, an outer race having a groove, and a plurality of ball bearings located between the inner and outer races, and in which the outer race groove is not round when in its position of use such that the ball bearings permit a greater freedom of movement of the inner race relative to the outer race in a first radial direction than in a second radial direction that is orthogonal to the first direction. Tensile or compressive forces may be applied to the bearing assembly to cause the part of the assembly to become not round.

摘要： A video camera or equivalent sensor is mounted on a vehicle and used to detect the lane markings on the road (usually the white painted lines). An associated signal processor (11) estimates the vehicle's lateral position in relation to the lane markings. An electric motor (4) coupled to the steering mechanism (1) is used to provide a torque input to the steering which may either assist or oppose the steering torque from the driver. The processor (11) is designed to assist the driver to maintain the vehicle's lane position by holding the vehicle at a set-point using a biasing torque. This simulates the effect of the lane being cambered upwards towards the lane edges. However the driver is able to override or cancel the effect if the driver applied steering torque exceeds a prescribed torque threshold.
