DD237497A1 - POSITIONING AND LUGGAGE OF SADDLE PLATES AND SADDLE COUPLINGS - Google Patents

Abstract

Field of application of the invention is the automotive technology. Objects of the application are chassis plates to be mounted on chassis frames. The aim is to create a simple and without additional material to be produced position fixing with Verschubsicherung saddle plates or fifth wheel couplings. To develop a backlash-free position assurance between chassis frame and fifth wheel plate or between fifth wheel and fifth wheel without changing the chassis frame, the object of the invention. Impressions are made in the saddle plate and knobs are introduced into the bearing surface, which is fastened to the chassis frame. When mounting the saddle plate, the knobs are introduced into the geometrically equal indentations without play. Fig. 1

Description

embodiment

The invention will be explained in more detail with reference to the following drawings.

It shows: " ·

Fig. 1: a sectional view of the position fixing and Verschubsicherung

Fig. 2: a plan view of Fig. 1 with round nubs

Fig. 3: a plan view of Fig. 1 with elongated knobs

Fig. 4 is a plan view of the fifth wheel plate with positional fixation on the chassis frame

In Fig. 1 it is shown how the nubs 3 of the fifth wheel plate 1 is inserted in the indentation 4 of the support 2. The lifting of the fifth wheel plate 1 from the support 2, caused by thrust occurring during driving, connect the screws 5. The required for a Verschubsicherung backlash is inventively achieved in that the angle α and the dimension A of the knob 3 and the indentation 4 equal are and between nubs 3 and indentation 4 a distance B be present

The threading of the pimple 3 in the indentation 4 of the support 2 is determined by the conical shape / which is at an angle α,

much easier. ι

Fig. 2 shows the nubs 3 in round, Fig. 3 the knobs 3 in an elongated design.

If, as in FIG. 3, tolerances in one direction are to be compensated, the dimension C in the indentation 4 of the support 2 is greater than the dimension D of the nub 3 of the saddle plate 1. The Schubsicherung takes place at right angles to the above

Flanks. ^Λ

In Fig. 4, the fifth wheel plate 1 is shown mounted with the support 2 on the chassis, wherein in the fifth wheel plate 1 each side a longitudinal and a transverse knobs 3 and the support 2 in the corresponding indentations 4 are selected. For further optional arrangement of the fifth wheel plate 1 on the support 2 more impressions 4 are provided in any number of distances E.

The arrangement chosen here in the example of longitudinal and transverse knobs 3 and indentations 4 has the advantage that the thrust protection acts in the longitudinal and transverse directions and tolerances can be compensated in both directions

Claims (2)

Claim of the invention: 1. Positional fixing and Verschubsicherung of fifth wheels and fifth wheels for sliding in the vehicle longitudinal direction and lockable by fasteners saddle plates, characterized in that edged knobs (3) and indentations (4), optionally having a different shape, provided with a plurality of specific distances (E), Both in a fifth wheel plate (1) and in a support surface (2) on the chassis can be arranged, wherein the side edges of the knobs (3) and the indentations (4) have an angle (α) which is smaller than 15 °. 2. Positional fixing and Verschubsicherung saddle plates and fifth wheel couplings according to item 1, characterized in that the flank angle (α) and a distance (A), as a measure of the outer edge of the knobs (3) and the inner edge of the indentations (4) are equal and that a defined distance dimension (B) between nubs (3) and indentations (4) is present. For this 1 page drawings Field of application of the invention The field of application relates to automotive engineering. Objects of the application are saddle plates to be mounted on chassis frames. , Characteristic of the known techn. solutions It is known that are used to fix the position and Verschubsicherung of saddle plates including fifth wheel couplings welded shear plates or welded shear plates with safety wedges to compensate for manufacturing tolerances. There are also known devices for adjusting a fifth wheel on a tractor in the vehicle longitudinal direction, as described in DE-GM 1 963 703, wherein the fifth wheel on slidable guides and lockable by engaging at least one spring-loaded locking member in each one of the sliding guides arranged latches. These connection principles are very time-consuming and material-intensive to produce. The disadvantage here is further that. the fifth wheel or fifth wheel can only be mounted in the position specified by the thrust plates. Object of the invention The aim is to create a simple and without additional material to be produced Lägefixierung with Verschubsicherung of saddle plates or fifth wheel couplings. The essence of the invention The technical task. The object of the invention is to develop a backlash-free position assurance between the chassis frame and fifth wheel or between fifth wheel and fifth wheel without changing the chassis frame. Features of the invention The same consist in that indentations are introduced into the saddle plate, which form on the opposite side of the sheet as sharp-edged studs. These nubs are in the assembly of the fifth wheel in geometrically equal Eiridrückungen, which are in the bearing surface, which is attached to the chassis frame, available, introduced without play. Another feature of the invention is that in the bearing surface at certain intervals further indentations are present, so that the fifth wheel or fifth wheel can be mounted according to the required axle loads with the same chassis in different positions. , These knobs and indentations are conical, thereby ensuring freedom from play and easy installation. This backlash is achieved in that the flank angle for nubs and indentations, and the extent of the outer edge of the knobs and the inner edge of the indentations are the same size and a defined distance between nubs and indentations is present.
