Embodiment Construction

[0053] The first embodiment of the present invention will be described with reference to the drawings. figure 1 To schematically show the configuration of the steering device 1 according to the first embodiment of the present invention. Reference figure 1 The steering device 1 mainly includes, for example, a steering member 2 of a steering wheel, a steering shaft 3, a first universal joint 4, an intermediate shaft 5, a second universal joint 6, a pinion shaft 7, a rack shaft 8 and a housing 9. The steering shaft 3 is coupled to the steering member 2. The steering shaft 3 and the intermediate shaft 5 are coupled to each other by a first universal joint 4. The intermediate shaft 5 and the pinion shaft 7 are coupled to each other by a second universal joint 6.

[0054] The pinion gear 7A is provided near the end of the pinion shaft 7. The rack shaft 8 is in the vehicle width direction ( figure 1 In the horizontal direction, and also called "axial direction X") extending in the cyl...

Abstract

A rack-pinion type steering device (1) comprises a pinion shaft (7); a rack shaft (8) disposed in a direction crossing with the pinion shaft; a housing (9) for accommodating the pinion and the rack shaft; and two bushes (11, 12) which is disposed to allow the pinion shaft to be located between the two bushes (11, 12) in the housing, and supports the rack shaft in a slidable way; at least one of the two bushes comprises: a bush main body (55) which is C-shaped in a side view when observed along a rack shaft direction, and is disposed between the rack shaft and the housing at one end part of the housing, and an elastic component (56) which is attached to the periphery of the bush main body to partially extend out from the periphery, is disposed between the bush main body and the housing, and presses the rack shaft to the pinion shaft through the bush main body.

Description

Technical field [0001] The invention relates to a rack-pinion type steering device, a method for assembling the rack-pinion type steering device and a bush used in the steering device. Background technique [0002] Rack and pinion steering systems for vehicles are known. The steering device disclosed in Japanese Patent Application Publication No. 2004-161117 (JP 2004-161117A) includes a pinion shaft coupled to a steering wheel and a rack shaft, the rack shaft is meshed with the pinion shaft, and according to the steering operation of the steering wheel The wheels are turned while sliding in the vehicle width direction. This steering device also includes a housing, a cylindrical bush, and a rack guide. The housing contains the rack shaft. The cylindrical bush is housed in the housing in a state of being fitted to the rack shaft, and elastically supports the rack shaft in this state. The rack guide urges the rack shaft toward the pinion shaft by being urged by the pressure spri...
