Abstract
The utility model belongs to automobile with small output volume petrol engine supercharger technical field, specifically a kind of aluminium matter intermediate structure for automobile with small output volume petrol engine supercharger.It comprises intermediate, steel bushing, cushion rubber and heat screen, and described steel bushing is located at outside the bearing rotor system in intermediate, and cushion rubber is located between steel bushing and intermediate, and heat screen is located between intermediate and turbine cylinder.After the utility model has the advantages that steel bushing quenching with Subsequent tempering, precision turning forms, match with floating bearing and there is good wear-resisting property, cushion rubber adopts oil resistant, heatproof, high elastic rubber material to make, it has sealing and vibration-damping function, intermediate constituent and engine-cooling system connect together, and take away heat by cooling water; Aluminum material thermal conductivity is high, improves cooling effect.Completely cut off heat, reduced cost, add reliability.
Description
Technical field
The utility model belongs to automobile with small output volume petrol engine supercharger technical field, specifically a kind of aluminium matter intermediate structure for automobile with small output volume petrol engine supercharger.
Background technique
Advocate the background of energy-saving and emission-reduction energetically in country under, be the common recognition in industry to miniature gasoline engine employing exhaust turbine pressuring technology.Exhaust turbine pressuring technology has increased substantially the power per liter of motor, significantly reduces oil consumption and discharge again simultaneously.Usually, after supercharging, power, moment of torsion increase by 30%, 40%, and oil consumption reduces 6-8%, and toxic emission all has greatly improved in amount and matter.At present, Ge great motor corporation of China, manufacturer do one's utmost to seize booster automobile market, and the sales volume expecting turbosupercharging gasoline car in 2015 will reach 1,500,000.Obviously, so simultaneously miniature gasoline engine turbosupercharger has a development at full speed.
Turbosupercharger is the core component of engine booster technology, primarily of centrifugal compressor, intermediate, turbo machine composition.Intermediate connects gas compressor and turbo machine, and carrier bearing and rotor-support-foundation system, except the mechanical load bearing rotor part, also to bear the heat load that turbine end transmits.Therefore, require that intermediate has good mechanical strength, simultaneously also will have good wear-resisting property for the bearing hole place matched with floating bearing.The middleware can seen in the market substantially all adopts ferrite ductile cast iron or alloy nodular cast iron.Advantage is not had in weight and processing.
Summary of the invention
The utility model, for the deficiency existed in above-mentioned technology, proposes a kind of aluminium matter intermediate structure for automobile with small output volume petrol engine supercharger.
The invention provides following technological scheme:
For the aluminium matter intermediate structure of automobile with small output volume petrol engine supercharger, it comprises intermediate, steel bushing, cushion rubber and heat screen, described steel bushing is located at outside the bearing rotor system in intermediate, and cushion rubber is located between steel bushing and intermediate, and heat screen is located between intermediate and turbine cylinder.
The inherent turbine end of this described intermediate is provided with constituent.
After the utility model has the advantages that steel bushing quenching with Subsequent tempering, precision turning forms, match with floating bearing and there is good wear-resisting property, cushion rubber adopts oil resistant, heatproof, high elastic rubber material to make, it has sealing and vibration-damping function, intermediate constituent and engine-cooling system connect together, and take away heat by cooling water; Aluminum material thermal conductivity is high, improves cooling effect.Completely cut off heat, reduced cost, add reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is enlarged diagram of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the aluminium matter intermediate structure for automobile with small output volume petrol engine supercharger is made up of intermediate 1, steel bushing 2, cushion rubber 3, heat screen 4.Aluminium matter intermediate structure for automobile with small output volume petrol engine supercharger studs with steel bushing 2 with carrier bearing rotor-support-foundation system in intermediate 1 center portion, and after steel bushing 2 quenching with Subsequent tempering, precision turning forms, and matching with floating bearing 6 has good wear-resisting property; Cushion rubber 3 is housed between steel bushing 2 and intermediate 1, and cushion rubber 3 adopts oil resistant, heatproof, high elastic rubber material to make, and it has sealing and vibration-damping function.
Aluminium matter intermediate structure for automobile with small output volume petrol engine supercharger have employed constituent 5 at turbine end.Intermediate constituent and engine-cooling system connect together, and take away heat by cooling water; Aluminum material thermal conductivity is high, improves cooling effect.
Aluminium matter intermediate structure for automobile with small output volume petrol engine supercharger is provided with heat screen 4 between intermediate 1 turbine cylinder, stops the high-temperature fuel gas of turbo machine to import intermediate into, reduces right bearing end temperature.Heat screen surface Spray magnetic, to reduce its thermal conductivity, reduces the heat that high-temperature fuel gas imports intermediate into.
Aluminium matter intermediate structure for automobile with small output volume petrol engine supercharger adopts aluminum material to alleviate the weight of pressurized machine, reduces cost, adds reliability.
