    The invention provides a steering assembly comprising a gear rack actuated by a pinion shaft rotated by a steering spindle wherein misalignment of the teeth of the gear rack and of the teeth of the pinion shaft can be readily adjusted for the entire flanks of both sides of the teeth so as to eliminate play and maintain constant engagement. A two part housing having relative pivotal motion on a spherical juncture is utilized as a bearing means between the housing members.

    专利说明:

    The invention relates to a rack and pinion control of a vehicle, preferably with a hydraulic booster, in which the force from the steering wheel is transmitted by means of a gear wheel to the j-rack and the latter rotates the steering wheels.
    A vehicle steering system is known, which contains a steering gear housing in which rake is placed, a gear, is installed in two bearings, one of which is housed in the steering gear housing and the other in the valve housing, which is connected with screws transmission, and regulating device Cl.
    However, this steering does not provide the ability to adjust the clearance in the mesh. 20
    The aim of the invention is to provide the possibility of adjusting the clearance in the engagement.
    The goal is achieved by the fact that in a rack and pinion steering TpaHcnopt- 25
    As a result, the bearing mounted in the steering gear housing is self-adjusting, and the valve housing is made with a spherical surface coupled to a spherical surface that is made on the steering gear housing with the possibility of fixing the relative position of these surfaces by means of an adjusting tool.
    In this case, the regulating device is made in the form of a finger with a head eccentric with respect to its axis, while the finger is installed in the valve box body, and the head is eccentric in the steering gear housing.
    C () The surface is made on the intermediate ring, rigidly. associated with the valve housing to interact with the spherical surface of the steering case, and the center of the spherical surfaces coincides with the center of the self-aligning bearing.
    FIG. 1 shows rack and pinion steering, general view; on Lig.2 regulating device, general view.
    In the crankcase, the steering gear 1 is mounted in the longitudinal direction of the toothed rack 2. The gear 3 is meshed with gear 3, which is connected through a control valve to the connecting element 5 of the steering shaft and through the steering shaft with the steering wheel. The rotation of the steering elbow is transmitted via gear to rack 2.. ; Gear 3 is installed in a non-tilting bearing 6 and a self-aligning bearing 7. A stationary bearing 6 is housed in a valve box 8 having a flange 9 and a gear housing 1 includes a flange 10. Both flanges 9 and 10 are connected by screws 11. -. To adjust the distance from the gear 3 TO the toothed rack 2 can vary. This is achieved so that gear 3 can be dismounted relative to the toothed rack 2. To this end, the end of gear 3, facing away from the connecting element 5 of the steering shaft, is installed in the self-aligning bearing 7 and the connection between the steering gear housing 1 and the valve box 8 is spherical surface. The flange 10 has an intermediate ring 12 with a spherical convex surface 13, which is located in the flange E of the valve box 8, as well as a corresponding spherical concave surface with a center located in the middle of the self-releasing bearing 7 "Thanks to this spherical surface of the valve box 8 gear 3 can be displaced relative to the steering gear housing 1. For this, at least one finger serves. but part 16 and is a corresponding (e 18 of the flange 10. The flange 9 has 11 holes for the screws 11, for
    the valve box 8 with gear 3 could be deflected relative to the steering gear housing V. The screws 11 on the flange 9 abut against the bearing washers 20 and 21 to ensure that when the flange 9 is rotated perpendicular to the screws 11 relative to the flange 10.

    Claims (2)
    [1]
    Due to the rotation of the finger 15 by means of the slot 22, the flanges 9 and 10 can move relative to each other. As a result, a gap is established between the toothed rack 2 and the gear 3, and correctness is observed when the side surfaces of the tooth engage. Claim 1. Car rack and pinion steering, containing the steering gear housing, in which the rack is located, gear mounted in two bearings, one of which is located in the steering gear housing and the other in the valve housing, which is connected to the steering housing transmission, and the adjusting device, I distinguish it with the fact that, in order to ensure the possibility of adjusting the gap in the gearing, the bearing installed in the steering gear housing is made self-adjusting, and the valve The box is made with a spherical surface connected to a spherical surface, which is made on the steering casing with the possibility of fixing the relative position of these surfaces by adjusting its device.
