FIELD: means of transport.

SUBSTANCE: protective tray for car power unit consists of a panel with mounting holes including rear holes for bolted or similar connections to install and fasten this tray in horizontal or close to horizontal position, at least under car engine. Panel is also provided with protective elements located directly before rear mounting holes. Each protective element is represented as protective hole with sizes in the drawing exceeding mounting hole dimensions in the same directions. Further more, protective hole sizes exceed also dimensions of the lower parts of the above connection to ensure automatic panel loosening in the specified attaching points and free downward displacement as a result of horizontal backward shifting under the action of axial component of dynamic loading F in case of frontal shock. Hole may be either through or blind (with bottom thickness being less panel thickness). Hole bottom is likely to be damaged at preset force F or panel gravity values or loose engine weight. Breaking bridge may be provided for between protective and mounting holes. Breaking bridge may be lacking. In this case, hole may be represented as longitudinal groove linked with a hole. It is preferable if the hole is made round. In addition, protective holes can be made before front mounting holes in plate.

EFFECT: improvement of car operation safety.
