Description
Technical field
The utility model relates to a kind of thermal shield, is specifically related to a kind of motor sheath thermal shield, belongs to the machinery industry such as automobile making, internal-combustion engine field.
Background technique
In the machinery industries such as current automobile making, internal-combustion engine, engine heat shield is mainly used in isolation engine exhaust system high temperature, guarantees that the thermosensitive element of surrounding normally works under suitable temperature environment.But because motor half sheath shaft gross distortion can occur under long-time high temperature condition, thus affect normal vehicle operation.Design of the present utility model is a novel engine heat shield, deforms, thus guarantee that semiaxis normally works mainly for preventing half sheath shaft long time running of motor.
Summary of the invention
The purpose of this utility model is to provide a kind of new work engine sheath thermal shield, installs on engine assembly and guarantees that motor semiaxis normally works.
For solving the problems of the technologies described above, the utility model adopts following technological scheme to realize.
Philosophy and technique scheme of the present utility model is: motor sheath thermal shield comprises thermal shield body, described thermal shield body comprises outer thermal baffle, inner layer heat-insulation plate, thermal-protective coating is had between outer thermal baffle and inner layer heat-insulation plate, there is outside turnup structure thermal shield side, and the inner side of turnup structure is provided with stiffening rib.
The outer thermal baffle of motor sheath thermal shield and inner layer heat-insulation plate are the aluminium sheet with convex closure, and convex closure height is 1-2mm, and the filler of the thermal-protective coating of inner layer heat-insulation plate and outer thermal baffle centre is ceramic fiber.
Below the stiffening rib arranged inside turnup structure on motor sheath thermal shield, the left and right sides is respectively arranged with a circular fixation hole, and the inner side thermal shield left side edge of thermal shield is provided with a circular fixation hole.
Motor half sheath shaft in the past adopts rubber material, and is arranged in below vent systems, but long-time work under the high temperature conditions easily gross distortion occurs, and cause semiaxis locking, vehicle is out of service.Therefore, adopt a kind of novel motor sheath thermal shield, be arranged between vent systems and half sheath shaft, intercept thermoconvection and the thermal radiation of vent systems.
The utility model is made up of outer thermal baffle, inner layer heat-insulation plate and intermediate thermal insulating layer.
As preferably, outer thermal baffle and inner layer heat-insulation plate adopt 0.3mm with the aluminium sheet of convex closure, and the height of convex closure is 1-2mm; The thermal-protective material of intermediate thermal insulating layer adopts 1mm ceramic fiber.
It is good that the utility model has heat-insulating efficiency, and quality is light, and higher forming ability and good sound attenuation performance, effectively protect semiaxis and normally work.
The beneficial effect of feature of the present utility model and generation is, prevents half sheath shaft under long-time high temperature condition, gross distortion occurring with a kind of motor sheath thermal shield, ensures that motor semiaxis normally works, normal vehicle operation.

Below in conjunction with accompanying drawing; by example, the utility model is further described; but following example is only the example in the utility model, do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claim.
Embodiment
As shown in Figure 1 and Figure 2, motor sheath thermal shield comprises thermal shield body, described thermal shield body comprises outer thermal baffle 1, inner layer heat-insulation plate 2, thermal-protective coating 3 is had between outer thermal baffle and inner layer heat-insulation plate, there is outside turnup structure thermal shield side, and the inner side of turnup structure is provided with stiffening rib 4.
The outer thermal baffle of motor sheath thermal shield and inner layer heat-insulation plate are the aluminium sheet with convex closure, convex closure height is 1-2mm, the filler of the thermal-protective coating of inner layer heat-insulation plate and outer thermal baffle centre is ceramic fiber, as preferably, outer thermal baffle and inner layer heat-insulation plate adopt 0.3mm with the aluminium sheet of convex closure, and the height of convex closure is 1-2mm; The thermal-protective material of intermediate thermal insulating layer adopts 1mm ceramic fiber.
Motor sheath thermal shield is provided with turnup structure 5, and below the stiffening rib within it arranged, the left and right sides is respectively arranged with a circular fixation hole, and the inner side thermal shield left side edge of thermal shield is provided with a circular fixation hole.
Motor sheath thermal shield of the present utility model, be arranged between vent systems and half sheath shaft, intercept thermoconvection and the thermal radiation of vent systems, can prevent half sheath shaft under long-time high temperature condition, gross distortion occurring, ensure that semiaxis normally works, thus ensure normal vehicle operation.
In sum, achieving originally is object with novel.
