Embodiment 1

[0019] Such as figure 1 , figure 2 , image 3 As shown, the design method for supporting on the rear axle trolley of the large passenger car chassis assembly line includes a support plate 5, a connector, a reinforcing rib, and a bottom plate 10, and is characterized in that it also includes a leaf spring bridge supporting folding plate 9 and a A grooved groove plate 8 with a bent elongated hole 14, the leaf spring bridge supporting the folding plate 9 is placed on the top of the supporting plate 5, and two grooves are welded symmetrically on one side of the leaf spring bridge supporting the folding plate 9 Plate 8, the grooved plate 8 is on the same side as the two reinforcing ribs I6 welded on the support plate 5; the connecting bolt 7 passes through the two bent-shaped elongated holes 14, and can go up and down in the bent-shaped elongated holes 14 Sliding; the groove back groove plate 8 is hinged with the reinforcing rib I6 through the connecting bolt 7; the bending angl...

Embodiment 2

[0021] It is basically the same as Embodiment 1, except that the bending angle of the bent elongated hole 14 is 115°, and the connecting parts are the fastening bolt 1 and the connecting bolt 7, both of which are hexagonal bolts.

Embodiment 3

[0023] It is basically the same as the embodiment 1, except that the bending angle of the bent elongated hole 14 is 125°.

Abstract

The invention relates to a method for designing a support on a rear-axle bogie used for a coach chassis assembling line. The support comprises a supporting plate, connectors, reinforcing ribs and a bottom plate, and is characterized by further comprising a foldable leaf spring supporting plate and two return trough plates with bent elongated holes, the foldable leaf spring supporting plate is disposed on the top of the supporting plate, the two return trough plates are welded on one side of the foldable leaf spring supporting plate symmetrically and arranged on the same side with the two first reinforcing ribs welded on the supporting plate. Connecting bolts penetrate through the two bent elongated holes and can vertically slide therein, the two return trough plates are hinged with the first reinforcing ribs through the connecting bolts, and the bending angle of each bent elongated hole ranges from 115 degrees to 125 degrees. The support designed by the method is high in universality, simple in structure and convenient in use.

Description

technical field [0001] The invention relates to chassis assembly of a large passenger car, in particular to a design method for the upper support of a rear axle trolley used in a chassis assembly line of a large passenger car. Background technique [0002] At present, the chassis of passenger cars in my country is mostly assembled on the ground tow chain assembly line, and the assembly trolley used on it is used to support the online chassis: generally one trolley is respectively located at the front and rear axles, and the chassis assembly trolley on the assembly line is connected to the ground tow chain through a pin. When the drag chain is moving at a constant speed, it drives the two trolleys to move forward synchronously, and the trolley drives the online assembly chassis supported on it to move forward, and it flows in different assembly stations. Traditionally, the car base is connected with the support bracket. When changing the model, it is necessary to replace the ...
