Abstract

The utility model discloses an engine exhaust system heat insulation structure, which comprises an exhaust pipe, and is characterized in that a semi-arc thermal shroud is arranged between the exhaust pipe and a heat-liable component to surround the exhaust pipe, the radius of the arc of the thermal shroud is larger than the radius of the exhaust pipe, and the thermal shroud is fixed on the exhaust pipe through a bracket. With the structure, the heat insulation structure has the advantages that heat emitted by the exhaust pipe is well obstructed for avoiding damaging other components, the problem of welding-off is avoided through connecting with rivets, and the space of a chassis is saved, and the N V H performance of the whole engine is free from being affected.

Description

A kind of engine exhaust system heat-insulating structure
Technical field
The utility model relates to engine exhaust system, particularly a kind of engine exhaust system heat-insulating structure.
Background technique
In the process of the motor of automobile operation, the Tail Pipe Temperature of engine exhaust system is very high, easily component around the vent systems is caused damage.If thermo-labile component are arranged around the outlet pipe, time has been grown and can cause damage to component on every side, at present the way of using is that outlet pipe is arranged in position away from thermo-labile component, but the space, chassis can occur does not meet the demands, do not reach problems such as heat-resisting distance.And common thermal baffle structure is easy to generate the problem of sealing-off, vibration abnormal sound in the long-term driving process of automobile, causes car load NVH performance to reduce.
In the process of motor operation, the outlet pipe of engine exhaust system is carried out heat insulation, and the space of saving automobile chassis is the problem that prior art need solve.
The model utility content
Technical problem to be solved in the utility model is, a kind of engine exhaust system heat-insulating structure is provided, and reaching heat insulation to the outlet pipe and the miscellaneous part of engine exhaust system, and saves the purpose in space, chassis.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of engine exhaust system heat-insulating structure, comprise outlet pipe, it is characterized in that: between described outlet pipe and the thermo-labile component, the thermal shield that is provided with half-circle-arc shape surrounds outlet pipe, and the radius of arc of thermal shield is fixed on the outlet pipe greater than the radius of outlet pipe and by support, to reach the effect for exhaust insulation.
A kind of engine exhaust system heat-insulating structure, described thermal shield are provided with a plurality of horizontal strip stiffening ribs, to reach the effect that strengthens thermal shield rigidity.
A kind of engine exhaust system heat-insulating structure, the length of described thermal shield is consistent with outlet pipe length, to reach sufficient effect of heat insulation.
A kind of engine exhaust system heat-insulating structure, described thermal shield is fixed by a plurality of rivets and a plurality of support, and support is welded on the outlet pipe, thereby solves the problem of sealing-off.
A kind of engine exhaust system heat-insulating structure, described thermal shield are ST12 * 0.8 aludip.
A kind of engine exhaust system heat-insulating structure, owing to adopt said structure, this structure has the following advantages: 1, well intercept the heat that outlet pipe comes out, avoid other devices are damaged; 2, owing to adopt rivet to connect, avoid the sealing-off problem; 3, save the space on chassis; 4, do not influence the NVH performance of car load.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is the structural representation of a kind of engine exhaust system heat-insulating structure of the utility model;
Fig. 2 is the Facad structure schematic representation of a kind of engine exhaust system heat-insulating structure of the utility model;
Fig. 3 is the cross-sectional view of a kind of engine exhaust system heat-insulating structure of the utility model;
In Fig. 1-3,1, thermal shield; 2, stiffening rib; 3, support; 4, rivet; 5, outlet pipe.
Embodiment
As Figure 1-3, a kind of engine exhaust system heat-insulating structure, comprise outlet pipe 5, it is characterized in that: between described outlet pipe 5 and the thermo-labile component, the thermal shield 1 that is provided with half-circle-arc shape surrounds outlet pipe 5, the radius of arc of thermal shield 1 is fixed on the outlet pipe 5 greater than the radius of outlet pipe 5 and by support 3, to reach the effect for exhaust insulation.
Thermal shield 1 is installed between outlet pipe 5 and the thermo-labile component, and the cross section is a half-circle-arc shape, can play good effect of heat insulation to outlet pipe and thermo-labile component like this.
Connect thermal shield 1 and support 3 with rivet 4, and support 3 is welded on the outlet pipe 5, effectively solved the problem of sealing-off.
Thermal shield 1 laterally be provided with the strong stiffening rib 2 of bar, strengthened the rigidity of thermal shield 1, make the vibration that thermal shield 1 produces can be because of motor operation and automobile running the time and produce abnormal sound, improved car load NVH performance.
What the material of thermal shield 1 adopted is ST12 * 0.8 aludip, and this aludip has good heat-blocking action, and intensity is higher relatively.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
