Usually, suspension type racks are mainly used on the front wheel four-wheeled vehicle and its design so that the front suspension device comprising a hydraulic shock absorber in the outer cylinder, constructed as a unit with the driven shaft, connected to a cylindrical spring suspension. Among these suspensions there is a type of construction in which the cylindrical axis of the suspension springs is rejected in the process with respect to an axis of the rack so as to allow smooth sliding of the piston rod of the shock absorber, is entered in the rack. There is another type of construction in which a cylindrical spring suspension is positioned so that the axis of the cylindrical spring suspension and axle front suspension are placed on one line. In each design the thrust bearing is placed between the fastening element of the car body and the top element of the nest of springs is, designed for installation in a cylindrical coil springs, making it possible to rotate went smoothly when the device front suspension is rotated together with the cylindrical spring suspension during operation of the steering mechanism.

This thrust bearing using the bearing which use balls or needles, or use a sliding bearing made of synthetic resin. The rolling bearing is the most appropriate, because it can be used to reduce the friction torque and can easily perform the work of the steering mechanism. However, since the rolling bearing is expensive, when necessary low cost, as a thrust bearing instead of the rolling bearing using the bearing.

By the way, any thrust bearing installed between the fastening element of the car body and the top element of the socket springs, designed for installation in a cylindrical spring suspension, as described above. However, since the top element of the nest of springs usually made from sheet metal, the top element of the nest of springs is relatively heavy. In addition, due to the fact that the top element of the nest of springs made of sheet metal, needs a coating to prevent rust, even if you use ithout the bearing instead of an expensive bearings to achieve low weight and low cost vehicle chassis, there is a limit to such attempts in achieving low weight and low cost, due to the weight, cost of manufacture, cost, Assembly, etc. the top element of the socket springs.

Above the bearing 1 slide for the front suspension used, setting it between one end section 62 of the cylindrical spring 61 suspension device 60 suspension type rack, as specifically shown in detail, Figures 1 and 2, and element 63 mounting, intended for the attachment device 60 suspension type rack to the body of a four-wheeled vehicle.

The element 63 of the mounting side of the car body, where built one end section 65 of the piston rod 64 of the hydraulic shock absorber device 60 suspension type rack includes a mounting plate 67, which is mounted on the body of a four-wheeled vehicle with a screw 66; enclosing element 68 having essentially the same shape as the upper yoke 3; a cylindrical element 69, in which is placed one end section 65 of the piston rod 64 and the support plate 70, through which passes one end section 65 of the piston rod 64; and an elastic element 73, in which one embed the end section of the mounting plate 67 and to which is attached by vulcanization of the enclosing element 68 and the cylindrical element 69 to merge into a single unit mounting play, enclosing element 68 and the cylindrical element 69. One end section 62 of the cylindrical spring 61 of the suspension is placed on the surface 36 of the socket springs.

In device 60 suspension type rack mounted using bearing 1 slide for the front suspension, as shown in Figures 1 and 2, the relative rotation of the lower holder 5 about the axis O in the direction R by means of a cylindrical spring 61 of the suspension is carried out smoothly due to the relative sliding in the same direction between the upper surface 41 of the thrust part 6 of the sliding bearing and the annular lower surface 2 of the upper casing 3 or the relative sliding in the same direction between the bottom surface 42 of the thrust part 6 of the sliding bearing and the annular upper surface 4 of the lower casing 5, as well as due to the relative sliding in direction between the inner surface 46 of the radial part 7 of the sliding bearing and a cylindrical side surface 29 of the lower casing 5 or the relative sliding in the same direction between the outer surface 45 of the radial part 7 of the sliding bearing and a cylindrical side surface 13 of the upper casing 3 during operation of the steering mechanism.

According to the bearing 1 slide for the front suspension, because in addition to the top about what IME 3, hard parts 6 of the sliding bearing and the radial part 7 of the sliding bearing, the lower yoke 5 made of synthetic resin, it is possible to achieve low weight and low cost. In addition, since the lower yoke 5 has on its bottom surface 25 and the surface 36 of the socket springs, intended for planting cylindrical spring 61 suspension, one end section 62 of the cylindrical spring 61 suspension may be taken by the lower holder 5, making it possible to exclude the top element of the nest of springs made from sheet metal. Thus, there is a possibility to avoid weight gain, due to the presence of the top element of the nest of springs made of sheet metal, and increasing the cost associated with the manufacture, building coating, and Assembly of the top element of the nest of springs made of sheet metal. In connection with the above-described advantages it gives an opportunity in the future to achieve low weight and low cost vehicle chassis.

Thus, the operation of the steering mechanism can be performed easily. In addition, because persistent item 6 of the sliding bearing can be positioned using the speaker section 27 having a cylindrical internal peripheral side and the protruding section 28 with the outer cylindrical peripheral side, the axial force can be reliably perceive with hard parts 6 of the sliding bearing. In addition, since the upper cylindrical section 24 is formed entirely on the radially mainly the Central part of the upper surface 23 of the annular support section 22, and surrounds the cylindrical section 14 of the upper casing 3, the lower gap 71 between the cylindrical section 14 of the upper casing 3 and the upper cylindrical section 24 can overlap the annular support section 22. As a result, there is an opportunity to effectively prevent dust, rain water, etc. into the gap 72 between the cylindrical section 14 of the upper casing 3 and the upper cylindrical section 24 through the lower gap 71. In addition, due to the fact that one end section 62 of the cylindrical spring 61 of the suspension can be kept with the help of the lower cylindrical section 26 relative movement in the radial direction, it is possible to prevent the displacement of one end section 62 of the cylindrical spring 61 on the Veski from the surface 36 of the socket springs.

Despite the fact that in relation to the bearing 1 slide for the front suspension lower yoke 5 design so that it includes the protruding section 27 having a cylindrical internal peripheral side and the protruding section 28 with the outer cylindrical peripheral side, an alternative or in addition, the bearing 1 slide for the front suspension can be constructed by mounting the upper casing 3, which includes a hanging area with a cylindrical internal peripheral side, which is similar to the speaker section 27 having a cylindrical internal peripheral side and completely hangs down from the annular lower surface 2 on the radial inner peripheral side, and additionally includes a hanging area with the outer cylindrical peripheral party, which is analogous to the speaker section 28 with the outer cylindrical peripheral side and completely hangs down from the annular lower surface 2 on the radial inner peripheral side, and by the location of the thrust part 6 of the sliding bearing between the overhanging section with a cylindrical internal peripheral side and an overhanging section with the outer cylindrical peripheral side.
