    • 专利摘要:
    A wedge brake arrangement for drum brakes on heavy road vehicles includes a brake cylinder push rod (29), plungers (26) axially movable perpendicularly to the push rod, and force transmitting rollers (32) between parallel wedge surfaces at the end of the push rod and on the respective plunger. In order to obtain full control over the reaction forces from the plungers (26) at brake operation the push rod (29) is guided by the housing (25) of the arrangement in the plane of the plungers by means of guide rollers (35) between plane surfaces at the end of the push rod (29) and in the housing (25), respectively, the surfaces being parallel with each other and with the axis of the push rod.

    The invention relates to mechanical engineering, in particular to wedge braking devices for heavy road transport vehicles.
    The purpose of the invention is to increase the reliability of operation by providing two-way control of reactive forces from the plungers and increasing the uniformity of the distribution of braking forces between the pads.
    Figure 1 shows a drum brake, partial view; figure 2 - diagram of the wedge brake device; on fig.Z -, wedge brake device on an enlarged scale, a general view; in Fig. 4. - the same cross section.
    Brake pads 1, equipped with friction linings 2, are made movable to interact with the brake rod 3, rotate with salt (not shown) of the vehicle under the influence of the wedge brake device 4. There is a spring 5 for reverse movement of the pads.
    The wedge brake device 4 contains a brake cylinder 6 operating under the influence of a medium, and the stem coming out of it is designed in the form of a wedge 7. A return helical compression spring 8 interacts with the stem. The force-transmitting rollers 9 are placed between the wedge 7 and the plungers 10, which are axially displaceable in the direction perpendicular to the direction of movement of the wedge

    In addition, two surfaces 13 and 14 are parallel to the axis of the rod 12 on the wedge 7, and corresponding two parallel guide surfaces 15 and 16 are made on the housing 11. Between the surfaces 13 and 15, 14 and 16 there are placed guide rollers 17 and 18. The rollers 17 and 18, like the rollers 9, must be mounted in a guide element, for example a holder (for simplicity, not shown in Fig. 2).
    A practical variant of the wedge device is shown in FIG. 3 and 4 (the left half of the device is shown in FIG. 3, since the right half is similar).
    In the housing 19, the plungers 20 are axially displaced. At the end extending from the housing 19, the plunger 20 is provided with an element 21 for interacting with the corresponding. stvuyu11 brake shoe (Fig. 1). 5 Membrane 22 between housing 19 and
    element 21 prevents the corpus 19 from moisture, dirt, etc. (shows a small part of the plunger 20 in cross section). A compensator may be installed in the device to select clearances (not shown. The compensators of both plungers 20 must be synchronized.
    The cylinder 23 of the brake cylinder is mounted with an axial displacement possibility movably in the housing 19 perpendicular to the plungers 20. A helical return seal 24 of the compression interacts with the rod 23. At the end

    7 so as to push the brake blocks of the stem 23, the central clique 1 is made to brake interaction with the brake drum 3. The slope of the edges of the Plungers interacting with the rollers 9 is the same as the slope of the corresponding wedge surfaces 7, i.e. the rollers 9 roll in on parallel surfaces. In actual structures, the rollers 9 can be enclosed in a cage or provided with a similar guide means, which is omitted in Fig. 1 for simplicity.
    Two pistons 10 are movably axially mounted in the housing 11. The UlTOK 12 brake cylinder is axially movable and perpendicular to the pistons 10. Cdin 7 is associated with the stem 12,

    A new surface 25 interacting with a force transfer roller 26, which in turn interacts with an end surface 27 of the plunger parallel to the wedge surface 25.
    On either side of the wedge surface 25, at the end of the rod 23, there is a directional surface 28, parallel to the axis of the rod 23. In the case 19, the reaction plate 29 is parallel to the axis of the surface 28, and a guide roller 30 is installed between the guide surface 28 and the reaction plate 29 The determined direction is defined by the roller 30 by a small flange 3 on the reactive plate 29 or the housing 19.
