    The invention provides a lightweight, economical rack steering mechanism comprising a booster pressure cylinder having a piston mounted on a toothed rack engaged by a pinion carried by an end closure element secured to the cylinder which has an end closure element at its opposite end. The rack extends in each direction out of the closure ends which effect housings for respective cylinder ends. The rack ends have connection to steering linkage means. The particularly novel feature is the use of lightweight metal, e.g., aluminum tubing, for the pressure cylinder. The mode of securing is by means of a corrugation adjacent each end of the cylinder which effects means in conjunction with locking or securing nuts and clamping or locking rings for fastening the housing ends to the cylinder. The aluminum tubing is protected against abrasive and twisting effect of nut tightening by arranging the securing nuts to abut the clamping rings which abut respective tubing corrugations nonrotatively. The securing nuts are rotatively tightened to grip the tubing through the clamping rings, being carried threadedly in respective end elements.

    The invention relates to the automotive industry, and more specifically to the steering gear: vehicle sham Rack and pinion steering gear for vehicles with power steering, social gear, and a gear rack connected to it, which is located on the maps, is known the steering gear, and the other in the handpiece, connected to the mentioned cylindrical tube with threaded fasteners installed in it for fixing the tube by means of retaining rings} fur nism is its considerable loemkost metal. The purpose of the invention is to reduce the magnitude of the mechanism, the drop chain is achieved in that in the rack and pinion steering gear for vehicles with a steering steering wheel containing a gear and a gear rack connected to it, which is located in bearings, one of the gear wheels is installed in the steering case, the other, in the handpiece, connected to the cylindrical casing with a cylindrical tube with rebarbos installed in it, 1 rigidly fixed with m rings for fixing by means of retaining rings, said cylindrical tube in places with Along with the crankcase, the nozzle is corrugated, with one end of the pipe with an outer corrugation, the largest diameter of which exceeds the outer diameter of the pipe, and the other with an internal corrugation, the largest diameter of which is less than the outer diameter of the pipe, and the pipe itself is made of light metal. The pipe can be made of aluminum. In addition, the end of the aforementioned pipe with an outer corrugation is connected to the crankcase of the steering mechanism, and the end of the corrugated pipe is connected to the front of the steering gear. One of the mentioned threaded stopping housings is installed in the crankcase of the steering mechanism with the ability to interact with the retaining ring, which is installed on the shaft. FIG. 1 shows the proposed frontal steering gear, longitudinal axis: Fez; in fig. 2 - place of the coaxial pipe of the state pipe with the crankcase of the left hand drive, section (magnified image); in fig. 3 - the junction of the pipe with the tip, section (enlarged image). The rack and pinion steering mechanism consists of a crankcase of the steering mechanism 1, a cylindrical tube 2 and a tip 3 connected to a cylindrical tube. In the crankcase of the steering gear 1, the pinion gear 4 is installed and the gear wheel 5 is in engagement with it, which has supports in the gear cards of the steering gear 1 and in the tip 3. For control, the gear rack 5; serves as a clamping element 6, working well-known method. A toothed rack 5 is connected to transverse steering rods 9 and 10 at both ends using axial joints 7 and 8. In addition, a working piston 1D is located on the toothed rack 5, which forms two pressure chambers 12 and 13. Hydraulic system for hydraulic steering management has a public. the device and therefore not shown in detail in the drawing. As shown in FIG. 2 and 3, the cylindrical tube, made of aluminum, at the junction with the steering gear housing 1 has an outer corrugation 14, and at the junction with the tip 3, an inner corrugation 15. For fastening serve threaded stop pipes 16 and 17. To avoid damage to the cylindrical tube 2 when mounting the steering, an anvil ring 18 is located between the outer corrugation 14 and the threaded locking ring 16. As a support for the threaded locking ring 17 spring locking ring 19, freely inserted into the inner corrugation 15. I lead and the gear is driven, both in the direction of movement of the handlebar via a steering wheel and the steering shaft. The distribution flow control distributor T1 1 is connected in a known manner to the steering shaft and is controlled by the latter. At the same time, a 4w pump about to be pumped (not shown) by an oil pipe podvoshgs to the plenum chambers 12 клв 13, the control force starting on the steering shaft and the & via gear pinion 4
