Abstract
The utility model discloses a heat insulating board structure, include: a heat insulation plate and a step washer; the step gasket comprises a plane section, an outward convex section is arranged on the surface of the plane section, and the convex section is inserted into a mounting hole arranged on the heat insulation plate. The utility model provides a heat insulation plate structure, which is fixed by a gasket with a step structure, and through the arrangement of the step gasket, the friction force of the flange surface at the head part of a bolt directly acts on the step gasket in the installation and connection process, thereby avoiding the problem that the heat insulation plate is deformed due to larger friction force; meanwhile, the raised section of the step gasket effectively protects the heat insulation plate from being extruded and crushed by axial force, and when the whole vehicle moves, the heat insulation plate cannot generate abnormal sound along with the vibration of the main speed reducer.
Description
Technical Field
The utility model relates to the technical field of vehicles, especially, relate to a heat insulating board structure.
Background
Along with people's standard of living's constantly improving, people are more and more intense to passenger car needs, also more and more big to the demand of high-end four driving motorcycle type, and the four driving motorcycle type needs match final drive unit, and partial motorcycle type is because final drive unit is great, and is nearer with the blast pipe distance, needs to install the heat insulating board additional and insulates against heat, avoids the final drive unit to be heated and leads to inside oil temperature too high to influence its performance output. Because the heat insulation plate is made of aluminum plates, the heat insulation plate and the large-size bolts suspended in front of the main speed reducer cannot share a fixed point.
The heat insulation plate and the front suspension of the main speed reducer share a large-specification bolt on the traditional four-wheel drive vehicle type main speed reducer, the bolt sequentially penetrates through the flat gasket, the heat insulation plate and the front suspension to be fastened with the auxiliary frame, and the heat insulation plate rotates along with the bolt in the fastening process to generate structural deformation, so that the problem of interference between the heat insulation plate and a flange plate at the front part of the main speed reducer is caused. The prior art mainly increases the heat insulating board fixed orifices through changing the main reducer casing on the main reducer casing, and this kind of scheme causes can't borrow current main reducer, and it is with high costs to change the main reducer casing.
Disclosure of Invention
The utility model aims at solving the deformation that the heat insulating board and the main reducer front suspension sharing fixing bolt screwed up the in-process and produced and interfere the problem of damage.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize:
a heat shield structure comprising:
the heat insulation plate 1 is provided with a mounting hole;
the step gasket 2 comprises a plane section 21, an outward convex section 22 is arranged on the surface of the plane section 21, and the convex section 22 is inserted into the mounting hole.
Further, the inner diameter of the mounting hole is larger than the outer diameter of the protruding section 22.
Further, the axial height of the convex section 22 is greater than the height of the mounting hole.
Further, the height of the plane section 21 is greater than the height of the convex section 22.
Compared with the prior art, the beneficial effects of the utility model are that:
according to the heat insulation plate structure provided by the utility model, through the arrangement of the step gasket, in the installation and connection process, the friction force of the flange surface at the head part of the bolt directly acts on the step gasket, so that the problem that the heat insulation plate is deformed due to the larger friction force is avoided;
meanwhile, the raised section of the step gasket effectively protects the heat insulation plate from being extruded and crushed by axial force, and when the whole vehicle moves, the heat insulation plate cannot generate abnormal sound along with the vibration of the main speed reducer.
Drawings
The invention will be further described with reference to the accompanying drawings:
FIG. 1 is a schematic view of an assembled heat shield structure and final drive;
FIG. 2 is an enlarged schematic view of area A of FIG. 1;
FIG. 3 is a cross-sectional view of a stepped washer;
in the above figures: 1. the main speed reducer comprises a heat insulation plate, 2 steps of gaskets, 21 planar sections, 22 convex sections, 3 bolts, 4 limiting plates, 5 main speed reducers, 6 main speed reducer front suspensions and 7 auxiliary frames.
Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following detailed description of the present invention with reference to the accompanying drawings makes it clear that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 3, the present embodiment provides a heat insulation plate structure, including:
the heat insulation plate 1 is provided with a mounting hole;
the step gasket 2 comprises a plane section 21, an outward protruding section 22 is arranged on the surface of the plane section 21, and the protruding section 22 is inserted into the mounting hole.
The inner diameter of the mounting hole is larger than the outer diameter of the convex section 22, the diameter of the mounting hole is 26mm, and the outer diameter of the convex section 22 is 24-24.3 mm;
the axial height of the protruding section 22 is larger than the height of the mounting hole, the axial height h of the protruding section 22 and the mounting hole matching surface is 1.1 mm-1.2 mm, and the height d of the mounting hole is 0.1mm smaller than the axial height h of the protruding section matching surface.
The height of the plane section 21 is greater than that of the convex section 22, and the height (H + H) of the step washer 2 is 3.7 mm-4.3 mm.
Referring to fig. 1, on heat insulating board 1, step packing ring 2 were fixed in sub vehicle frame 7 through bolt 3 and main reducer front overhang 6, main reducer 5, the rotatory in-process of bolt 3 tightening, the upper surface of the plane section 21 of step packing ring 2 was laminated with rear main reducer's limiting plate 4, the lower surface of the plane section 21 of step packing ring 2 was laminated with bolt 3, and the head flange face frictional force direct action of bolt 3 was in on the step packing ring 2, avoided heat insulating board 1 warp because of receiving great frictional force, simultaneously the step height of step packing ring 2 effectively protects heat insulating board 1 avoids axial force extrusion conquassation, and when the whole car moved, heat insulating board 1 can not vibrate along with main reducer 5 and produce the abnormal sound.
