    An enclosure means for a cylinder end of a rack steering mechanism is provided comprising a bearing within the cylinder end for slidably supporting a rack and which is secured to the cylinder by nesting corrugations of the cylinder and the bearing coacting to lock the cylinder and bearing together. A sleeve of synthetic material surrounds the cylinder end and has an inwardly directed radial corrugation nesting within the corrugation of the cylinder locking it to the cylinder. The sleeve is provided with a ported through passage for equalizing air to be transferred between respective bellows at the ends of the rack which protect ball joints connecting the rack to a steering mechanism.

    (RIVER STEERING MECHANISM FOR TRANSPORT
    TOOLS WITH STEERING POWER STEERING
    one
     The invention relates to a transport engineering, and more specifically to a rack and pinion steering mechanisms of vehicles.
    A rack and pinion steering mechanism 5 for a vehicle with power steering is known, comprising a gear located in the steering housing and a gear rack associated with it, resting on the steering housing and on the lug connected to said cylindrical housing 1.
    A disadvantage of the known mechanism is that the attachment of the tip with the cylindrical tube was carried out by means of a threaded ring. The outer part of the cylindrical tube had a recess, in which 20 were laid spring retaining ring. This is a snap ring. served as a stop for screw-on threaded ring. Such constructions are made in manufacture and required 25
    La use of a large number of parts. This caused a high cost of manufacture and assembly. In addition, during the period of operation there was a danger that as a result of vibration, shock, etc. spring snap ring could get out of place, which deduced steering control.
    The purpose of the invention is to reduce the cost of construction and increase operational reliability.
    This goal is achieved by the fact that the mechanism is equipped with an elastic attachment. The body is made of a neck at the end of the cylindrical tube connected to the handpiece, and the handpiece is a support piece that is capable of interacting its internal surface with the rack and matching the external surface through the groove fitting made
    with an annular projection directed toward the cylindrical tube fixed in the neck of the cylindrical tube.
    FIG. 1 shows a rack and pinion steering mechanism, longitudinal section; in fig. 2 - the junction of the cylindrical tube and the tip. Section (on an enlarged scale)
    The hydraulic rack and pinion steering gear comprises a steering gear housing 1, a cylindrical tube 2 connected to it and a tip 3 also connected to the cylindrical tube. In the steering gear housing there is a drive gear 4 and a gear rake 5 that is in engagement with it. A toothed rack 5 is located in the crankcase 1 of the steering gear and in the tip 3. For the direction of the toothed rack 5 serves pressure rod 6. On the cylindrical tube 2 there is also a working piston 7 forming two pressure chambers. Using axial hinges 10 and 11 of the toothed rail 5, they are connected at both ends with the transverse steering rods 12 and 13. Corrugated covers 1 and 15 serve to protect the hinges and are connected to each other to compensate for the air through pipe 1b.
    Tip 3 (FIG. 2) consists of an inner support part 17 and an outer connection part 18. The support part 17 has a recess 19 and sealing rings 20 and 21 for sealing the pressure chamber 9. The cylindrical tube 2 has a neck fitted to the recess 19, which is made after the insertion of the support part 17 is used to implement the corresponding tools. The connecting part 18 consists of a synthetic material. It has an annular protrusion 22 directed toward the cylindrical tube, by means of which the connecting piece 18, when seated on the cylindrical tube 2, engages with the neck of the tube. The connecting part 18 has a connecting nipple 23 with a hole for connecting to the pipeline 16. A groove 24 is made to fasten the corrugated cover 15 to the connecting part 18. The supporting part 17 is made of gray cast iron, thereby eliminating the need for using a special rack bearing 5 Thanks to the separation of the tip the cost is reduced in two parts and he can better accomplish the tasks assigned to him. The rack is supported by an internal support part. At the same time, this part provides
    also a connection with a cylindrical tube. During installation, the support piece is pushed into the cylindrical tube and then the cylindrical tube at the place where the undercut is located is supplied
    the neck. This operation can be carried out mechanically by means of a penetrating ring around the entire perimeter. The neck in a cylindrical tube can also be performed manually topically,
    distributed around the perimeter. So about- At one time, the support piece is securely and firmly connected to the cylindrical tube.
    The outer elastic connecting piece is pulled during mounting onto the Cylindrical tube and is secured with an annular protrusion in the formed neck on the cylindrical
    the pipe. Since the connecting piece does not experience any special loads, it can be made of a simple material.
    Invention Formula
    A rack and pinion steering gear for a vehicle with power-assisted steering lights contains a gear located in the steering housing and a toothed rack associated with it, resting on the steering housing and on the handpiece connected to the cylindrical housing mentioned in the housing, which differs from TeWj in order to reduce the cost of construction and increase operational reliability, it is provided with an elastic connecting piece; at the end of a cylindrical tube connected to the tip, a neck is made, and the tip edstavl is a support piece mounted to cooperate inside its surface with a rack and a conjugated outer surface means formed thereon bore with neck surface, and the resilient connecting part is formed with directed towards the cylinder tube an annular protrusion fixed in the neck of the cylinder tube.
