APPARATUS FOR PRESSING A RACK ONTO A PINION, AND STEERING SYSTEM FOR A MOTOR VEHICLE WITH AN APPARATUS OF THIS TYPE
The disclosure relates to an apparatus for pressing a rack onto a pinion, with a pressure piece. The pressure piece being arranged within a housing and to be displaceable in an axial direction of a center longitudinal axis. A bearing element is fixed on the housing in the axial direction with respect to the center longitudinal axis. A prestressing element acts in the axial direction. The pressure piece is loaded by the prestressing element which is arranged between the pressure piece and the bearing element with a prestressing force in the axial direction with respect to the center longitudinal axis and directed away from the bearing element. An adjusting ring which is arranged between the bearing element and the pressure piece. At least two inclined faces of the adjusting ring and an adjusting section bear against one another. In order to be able to reduce the production outlay and/or realize a more compact overall design, a force application disk is arranged between the adjusting ring and the adjusting section.
Rotary to linear torque transmission device
A torque transmission device has a pinion that includes a plurality of rollers that mesh with a plurality of teeth of an output. Each roller is supported by a bearing having rotating bearing elements. A clearance compensation for the diametrical difference between a diameter of each roller and an inscribed diameter of the associated rotating bearing elements is included in the plurality of teeth of the output such that there is no interference between the plurality of rollers and the plurality of teeth.
Steering apparatus
Disclosed is a steering apparatus including: a mounting housing which is formed on one side of a rack housing and has first threads formed on an inner circumferential surface thereof; a yoke body which is provided inside the mounting housing and supports a rack bar located inside the rack housing; and a pressing member which is provided inside the mounting housing, has second threads formed on an outer circumferential surface thereof, and is coupled to the mounting housing in a state in which the second threads are coupled to the first threads and are separated from the yoke body.
Steering gearbox
A steering gearbox is equipped with a casing, a rack shaft, and a plurality of bushes. The rack shaft is accommodated in a casing to be movable in an axial direction. The plurality of bushes support the rack shaft to be movable in the axial direction and are attached to the casing.
SHAFT LOCKING METHOD USING A GEAR RACK AND TOOTHED LOCKING LEVER
A shaft locking mechanism includes a rack disposed on a translating shaft and a toothed locking lever disposed on a corresponding translation post. The toothed locking lever engages the rack in a locked orientation to prevent the shaft translating within the translation post. The toothed locking lever is disengaged during translation and the shaft may be translated and locked in place with very granular adjustability. A control rod release mechanism may be biased to maintain the toothed locking lever in the locked orientation. A cam feature on the toothed locking lever engages the body of the control rod which defines a recessed portion that coincides with the cam while in an unlocked orientation.
APPARATUS FOR PRESSING A TOOTHED RACK AGAINST A PINION
The disclosure relates to an apparatus for pressing a toothed rack against a pinion, having a pressure piece. The pressure piece can be arranged so as to be displaceable inside a housing and in an axial direction of a centre longitudinal axis. A bearing element that can be fixed on the housing in an axial direction with respect to the centre longitudinal axis, having a prestressing element that acts in an axial direction. Action of the prestressing element arranged between the bearing element and the pressure piece subjected the pressure piece to a prestressing force in an axial direction with respect to the centre longitudinal axis and directed away from the bearing element. A sliding element is arranged on a side, facing away from the prestressing element, of the pressure piece for the purpose of bearing against the toothed rack. In order to reduce the production outlay and/or allow a more compact design, on the side bearing against the sliding element, the pressure piece has a contour for compensating tolerances. The contour interacts with the sliding element.
APPARATUS FOR PRESSING A TOOTHED RACK AGAINST A PINION
The disclosure relates to an apparatus for pressing a toothed rack against a pinion, having a pressure piece, wherein the pressure piece can be arranged so as to be displaceable inside a housing and in an axial direction of a centre longitudinal axis, having a bearing element that can be fixed on the housing in an axial direction with respect to the centre longitudinal axis, having a prestressing element that acts in an axial direction, wherein, as a result of the prestressing element being arranged between the bearing element and the pressure piece, the pressure piece is subjected to a prestressing force in an axial direction with respect to the centre longitudinal axis and directed away from the bearing element. In order to be able to reduce the production outlay and/or realize a more compact design, the apparatus is characterized in that a sliding element is arranged on a side, facing away from the prestressing element, of the pressure piece for the purpose of bearing against the toothed rack, wherein the sliding element is designed with a spring function in an axial direction of the centre longitudinal axis in order to compensate tolerances.
TOOTHED PORTIONS ENGAGEMENT ADAPTATION MECHANISM AND LOGISTICS SYSTEM
The present disclosure relates to a toothed portions engagement adaptation mechanism and a logistics system. The toothed portions engagement adaptation mechanism includes: a rack including a first side and a second side arranged opposite to each other; a first guide tooth provided on the first side; a second guide tooth movably provided on the first side, the second guide tooth being farther than the first guide tooth from the second side; and a gear configured to partially engage the rack from the first side, and move towards the second side so as to completely engage the rack, wherein at least one of the first guide tooth and the second guide tooth is configured to engage the gear during the movement of the gear from the first side toward the second side.
VEHICULAR STEERING DEVICE
A vehicular steering device includes a turning shaft, a housing storing therein the turning shaft, a stopper provided at a shaft end of the turning shaft, and an annular elastic body. An opening of the housing is formed in a U-shaped cross-sectional shape and in an annular shape opened toward the stopper by an external cylinder portion and an internal cylinder portion. The elastic body includes a first elastic portion and a second elastic portion. The first elastic portion is supported by an inner circumferential surface of the external cylinder portion and the bottom surface, and is provided with a first clearance from an outer circumferential surface of the internal cylinder portion. The second elastic portion extends toward the stopper from the first elastic portion, and is provided with a second clearance larger than the first clearance from the inner circumferential surface of the external cylinder portion.
RACK BAR SUPPORT APPARATUS OF VEHICLE STEERING APPARATUS
According to the present embodiments, noise can be reduced by compensating for clearance caused by the wear of a rack bar support member, assembly convenience can be improved by simplifying a structure, and an installation space can be easily ensured by reducing the overall size of a steering apparatus.
