SU286524A1 - CAR PLATFORM WITH FLOOR HEATING HEAT CARRIER - Google Patents

Description

The invention relates to vehicles, mainly to automobiles, which are designed to heat the cargo carried in the bodywork.

There are platforms for cars with underfloor heating, for example engine exhaust gases, comprising a body base formed by longitudinal corrugations of the bottom sheet and a panel of the upper floor sheet, longitudinal channels for the coolant, transverse hollow beams, the rear of which is connected to the side racks of the body sides to form a closed volume circulation of the coolant and its release into the atmosphere through the holes in the racks. However, the known platforms have the disadvantage that during operation of a vehicle with heating on, the silencer, which is a self-contained unit, is not used.

In the proposed construction, the silencer as an independent vehicle assembly is excluded, and platform elements are used as a silencer.

This goal is achieved due to the fact that a closed volume formed by one of the middle crossbars of a platform with side columns is divided by partitions into a through channel and sequentially placed cavities located above it, connected

openings with a channel so that an acoustic filter is formed.

Another distinctive feature of the proposal is the installation of a hollow casing with shutters under the platform. The casing is connected to the longitudinal and through channels, and the coolant enters the casing through the inlet pipe. This feature allows the coolant to be directed either to the heating of the platform or through the silencer to the atmosphere.

FIG. 1 shows the platform of a vehicle with floor heating, left view; in fig. 2 - the same, top view; in fig. 3 is a section along the line A-A in FIG. 2; on

FIG. 4 - detail B in FIG. 2

Under the platform 1 of the truck of a dump truck with a body 2, a hollow casing 3 is installed, which communicates with openings a and b with the cavity of the longitudinal beam 4 of the body. Cavity beam 4

divided by partitions 5 into two parts - front and rear. The front part of the cavity of the beam 4 is connected through a hole in the cavity of the front cross member 6, which, in turn, is connected to the longitudinal channels 7 located along the base of the body. The longitudinal channels are formed by corrugations of the floor sheet 5 and a panel of its top sheet 9. The transverse hollow beams 10 and 11 are connected to the side posts 12 and 13

This is the volume for the circulation of the coolant, and it is released into the atmosphere through the holes r and (5B lateral racks.

Inside the closed volume, partitions 14, 15, 16, 17 are installed, dividing this volume into a through channel 18 for the passage of heat transfer fluid and closed cavities 19, 20 communicating with openings e and g with channel 18, forming with it an acoustic filter that reduces noise. exhaust. In the housing 3, a flap 21 is pivotally mounted on the axis 22 with locking in several positions. Exhaust gas, which is a coolant, from the engine enters the casing at the nozzle 23 through the aperture.

At the position / flap 21, the gas entering the casing 3 fills the cavity of the beam 4, from where it flows into the longitudinal channels 7 for heating the body.

When the damper is in the // position, the gas enters the transverse hollow beam 11, and through the holes in the side pillars 13 enters the atmosphere. At the same time, a part of the gas, a circular one in the closed cavities 19 and 20, extinguishes the damping effect on the sound vibrations of the moving gas.

At intermediate positions /// and IV of the flap 21, gas in a different volume follows both directions.
