摘要:
A cam follower includes an oval rotational body which is rotationally supported on a fixed pin, and in which an outer circumferential shape thereof is an oval, a long axis of the oval is longer than a width of the cam groove, and a short axis of the oval is shorter than the width of the cam groove, the oval rotational body being biased and being rotated by a biasing spring in one direction about the fixed pin. As a consequence, when a steering wheel is in a neutral position, the outer circumferential surface of the cam follower comes into contact with both side surfaces of the cam groove in the width direction of the cam groove and gaps therebetween can be eliminated. As a result, neutral stability of the steering wheel and steering feeling during straightforward traveling are improved.

In a manufacturing method for a hollow rack shaft, and a hollow rack shaft, a tubular member (23) having a planar flat portion (22) that is formed in part of a tubular body portion (21) is sandwiched and held between a cope (25) and a drag (26) that has a tooth-shaped portion (29) substantially symmetrical with rack teeth (7) so that a surface (22a) of the flat portion (22) is in contact with the tooth-shaped portion (29). A back die (14) having a plurality of protrusions (15) is arranged so that the protrusions (15) face groove portions (29a) of the tooth-shaped portion (29) across the flat portion (22), and the back die (14) is pressed against the flat portion (22) to form the rack teeth (7) to thereby manufacture the rack shaft.

A steering apparatus includes: an input shaft that transmits a steering force input from a steering wheel; an output shaft that transmits a steered force by which wheels are steered; and an eccentric pin mechanism that includes an eccentric cam and an adapting plate. The output shaft is arranged at a position that is radially offset from the input shaft, and is connected to one of the eccentric cam and the adapting plate. The other one of the eccentric cam and the adapting plate is connected to the input shaft. A middle accommodation member that accommodates the eccentric pin mechanism is formed separately from an input-side accommodation member that accommodates the input shaft and an output-side accommodation member that accommodates the output shaft.

A cam follower (70) includes an oval rotational body (72) which is rotationally supported on a fixed pin (71), and in which an outer circumferential shape thereof is an oval, a long axis of the oval is longer than a width of the cam groove (64), and a short axis of the oval is shorter than the width of the cam groove (64), the oval rotational body (72) being biased and being rotated by a biasing spring (77) in one direction about the fixed pin (71). As a consequence, when a steering wheel (39) is in a neutral position, the outer circumferential surface of the cam follower (70) comes into contact with both side surfaces (64S) of the cam groove (64) in the width direction of the cam groove (64) and gaps therebetween can be eliminated. As a result, neutral stability of the steering wheel and steering feeling during straightforward traveling are improved.

A pressure sensor is constructed to include a sensor housing formed of metal, and a connector housing mainly formed of synthetic resin. The connector housing includes a shoulder portion thereof in the form of a metal plate having an inner and an outer periphery thereof. On the shoulder portion, there is formed a juncture of the sensor and connector housing as a result of joining the sensor and connector housing by curling a projecting portion or one of two end portions of the sensor housing toward the shoulder portion. Wherein, the curling is performed under engagement of the sensor and connector housing therebetween, for assembling the pressure sensor.

A transmission ratio variable mechanism is provided with: an input member and an output member capable of rotation about a first axis; an inner race for differentially rotatably coupling to each member; an outer race for rotatably supporting the inner race via a rolling element; and a transmission ratio variable mechanism-use electric motor for rotation-driving the outer race. A second axis which is a center line of the inner race and the outer race is inclined to the first axis. A first concave-convex engaging section for engaging one side end surface of the inner race and a power transmission surface of the input member corresponding to the one end surface are arranged. There is provided a second concave-convex engaging section for engaging the other end surface of the inner race and a power transmission surface of the output member.

A steering apparatus includes a first shaft coupled to a steering wheel, a second shaft arranged to be eccentric relative to the first shaft, and a joint mechanism for coupling the first shaft and the second shaft to each other. The joint mechanism includes a cam having a cam groove that extends in a direction perpendicular to the first shaft, a cam follower that can slide in the cam groove, an eccentric pin for coupling the second shaft and the cam follower to each other at a position eccentric relative to the second shaft. An outer cylinder serving as a protective member is arranged concentrically with the eccentric pin, so as to surround the outer circumference of the eccentric pin. At least part of the eccentric pin and the outer cylinder is arranged in the cam groove.

A motor vehicle steering system includes a transmission ratio variable mechanism capable of changing a transmission ratio, and a steering-assist-force imparting mechanism. The transmission ratio variable mechanism is provided with an input member and an output member capable of rotation about a first axis, a first bearing ring for differentially rotatably coupling to each of the input and output member, a second bearing ring for rotatably supporting the first bearing ring via a rolling element, and an electric motor for rotation-driving the second bearing ring. A second axis that is a center line of the first bearing ring and the second bearing ring is inclined relative to the first axis.

A pressure sensor 11 is provided with a connecter housing 30 having a pressure sensing element 20 arranged on an end surface thereof, a sensor housing 40 constructed to have the connecter housing 30 inserted thereinto, a pressure chamber 452 defined between the end surface of the connecter housing 30 and the sensor housing 40, and a compensation circuit 21 for performing the processing and operation of a measured signal of the pressure sensing element 20 to output the measured signal. The compensation circuit 21 is composed of a data communication interface section 211 for receiving the compensation data radio-transmitted thereto, a memory section 212 for storing the compensation data, a compensation data writing section 214 for taking thereinto the compensation data from the data communication interface section 211 and for writing the compensation data in the memory section 212, and a signal processing section 213 for performing the processing and operation of the measured signal based on the compensation data stored in the memory section 212.
摘要:
A pressure detection device for detecting an increase of pressure acting thereon includes an electrically conductive device housing which has an accommodation bore extending inward from one end of the device housing and a slide bare extending between the accommodation bore and the other end of the device housing. A piston is slidably disposed within the slide bore and adopted to receive a pressure, and a terminal serving as one electric contact is fixed to the accommodation bore via an electrical insulator. A disk spring serving as the other electric contact deforms due to a pressing force of the piston and coming in contact with the terminal. The pressure detection device further comprises an electro-functional member attached to either the terminal or the disk spring in which the electro-functional member is changeable its electric resistance due to an impressed pressing force acting thereon. Further, at least one of a notch and a chamfer is provided on the electro-functional member for changing its electric resistance characteristic.
