FIELD OF THE INVENTION The invention relates to a transport engineering, in particular, to super heavy mining dump trucks.

A device for hanging a mobile vehicle cab on its frame is known.

In this device of the floor, the beam with a slot is not protected from the penetration of foreign objects, dirt and precipitation, which during the operation will make it difficult to move the cabin along the rollers. When the vehicle is moving, its cabin is subjected to vibration from the engine and road irregularities. In the known device for mounting the cabin on the frame, it is not possible to provide a rigid connection of the beam resting on the rollers mounted cantilever on the axes in the bar. The rigidity of the beam and the stability of the size of the slot in it cannot be ensured, since this will cause, under external loads, an increase in the play in the roller-beam joints and the axis of the roller-beam. The location of the shock absorbers between the cabin and the beam will have a negative effect when moving the cabin, and their braid deformation during fixation does not guarantee the same stiffness characteristics of the shock absorbers when exposed to external loads. During operation, the cab vibration load will increase and reduce the efficiency of the device.

The purpose of the proposal is to simplify and facilitate the construction and increase reliability in operation.

For this purpose, the guide cabins are made in the form of channels, with their open part facing the frame guides, installed with the scope of these guides and representing the frame elements of the cab, the anti-friction elements are made in the form of tapes of anti-friction material attached on the upper edges of the vehicle's frame guides, the cab vibration damping shock absorbers are installed between the frame guides and the frame itself, and the fixing elements of the guides relative to each other are made in the form of rod rods ementov installed in openings made transversely in the guide frame and the cab.

There is no known technical solution to the vendor with features that distinguish the proposal from the prototype.

FIG. 1 shows the suspension of the mobile cabin on the vehicle frame; FIG. 2 is a detail view 1 of FIG. 1 (longitudinal section of the device for hanging the mobile cab on the vehicle frame); in fig. 3 - section AA

Fig. 2 (cross-section along the shock absorber of the device for hanging the mobile cab on the vehicle frame).

The device for hanging the mobile cabin 1 on the frame 2 of the vehicle contains guides 3 fixedly mounted on the cab 1 and covering the guides 4 mounted on the frame 2. Shock absorbers 5 for damping the vibration of the cab are installed between the guides 4 and the frame 2. Anti-friction elements 6, in the form of tapes, are fixed on the upper edges of the guides 4. The guides 3 have slots 7, and the guides 4 have threaded bushings 8.

In the working (middle) and intermediate positions, the cabin 1 is fixed by screwing the rod elements 9 into the threaded bushings 8 through the slots 7. At the same time, the guides 3 and the guides 4 are fixed between each other.

If it is necessary to move the cabin 1, the device is released by turning the core element 9 out of the threaded sleeve 8, the cabin is shifted in the necessary direction.

Claims (1)

Apparatus of the Invention A device for hanging a movable cabin on a vehicle frame, comprising guides fixed on the cab and frame of the vehicle, anti-friction elements fixed on the guide frames and mounted with the ability to interact with the guide cabs to ensure their mutual longitudinal movement, fixing elements guides against each other and vibration damping of the cabin, located between the latter and the frame of the vehicle, differing from those That, in order to simplify and simplify the construction and increase reliability in operation, the guide cabins are made in the form of channels, with their open part facing the frame guides, installed with the coverage of these guides and representing the cab frame elements, antifriction elements in the form of tapes of antifriction material attached to the upper edges of the vehicle's frame guides, dampers for damping vibration of the cab are installed between the frame guides and the frame itself, and the fixation elements guides relative to each other are in the form of bar elements mounted in openings made in Ltrperechno guide frame and the cab. g 1766760 one /  , jj i 1 u- -U -kI ffl / g /
