Description
Technical field
The utility model relates to the component in turbosupercharger, particularly a kind of turbine box venting valve transmitting assemblies.
Background technique
The present stage environmental requirement of motor complete machine is more and more higher, and turbine box is as the critical piece of motor, and its exhaust gas leakage amount also becomes priority control object, if the exhaust gas leakage amount of turbine box increases, car load will be caused to discharge and do not reach environmental requirement.
Under normal operation, the high-temp waste gas that motor is discharged enters turbine box impulse turbine rotor by engine exhaust pipe, drives coaxial compressor impeller work, thus provides boost pressure to motor.But high-temperature exhaust air under pressure, the gap location easily existed from turbine box venting valve transmitting assemblies leaks.
The patent No. is that the utility model patent of CN201020623113.4 discloses a kind of turbosupercharger whirlpool end venting valve driving component with seal ring, as shown in Figure 7, comprises axle sleeve 8, valve drive shaft 7 and seal ring 9.Spielpassung is adopted between axle sleeve 8 and valve drive shaft 7, valve drive shaft is provided with the annular seal groove installed for seal ring 9, seal ring 9 is arranged in the annular seal groove on valve drive shaft 7, prevents waste gas from leaking from the gap location between valve drive shaft 7 and axle sleeve 8 by seal ring 9.
But in order to meet the matching requirements of seal ring 9, gap between axle sleeve 8 and valve drive shaft 7 needs the larger of setting, when axle sleeve 8 length is shorter time, there is the situation that valve drive shaft 7 rocks, add the wearing and tearing of valve drive shaft 7 and bring new gas leakage hidden danger.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, and provide a kind of turbine box venting valve transmitting assemblies of anti-gas-leak.Its structure is reliable, avoids the situation that valve drive shaft rocks, has stopped gas leakage hidden danger.
The technical solution of the utility model is: a kind of turbine box venting valve transmitting assemblies, comprises valve drive shaft, axle sleeve and seal ring.
Described valve drive shaft is provided with the annular seal groove for installing seal ring.
Two ends in described axle sleeve are respectively equipped with diameter holes and hole, large footpath, and the connecting part in diameter holes and hole, large footpath is provided with circular groove.
Seal ring is arranged in the annular seal groove on valve drive shaft, valve drive shaft is arranged in axle sleeve, diameter holes in valve drive shaft and axle sleeve adopts Spielpassung, diameter holes in axle sleeve realizes guiding, anti-beat function, reduce the wearing and tearing of axle sleeve and valve drive shaft contact segment, increase the service life.Hole, large footpath in seal ring and axle sleeve adopts interference fit, and the external cylindrical surface of seal ring coordinates with hole, large footpath and carries out circumferential seal.
The quantity of described seal ring is two, and the end face of two seal rings fits tightly.
The utility model compared with prior art tool has the following advantages:
1, axle sleeve hole is shoulder hole, the diameter holes of shoulder hole and transmission shaft Spielpassung, the hole, large footpath of shoulder hole and the outer peripheral surface interference fit of seal ring.Less gap width can be adopted between the diameter holes of said structure shoulder hole and transmission shaft, effectively prevent transmission shaft from rocking, and good guiding can be realized, reduce the wearing and tearing of contact segment, increase the service life.There are enough gaps between hole, large footpath and transmission shaft, are convenient to design and the assembling of seal ring.
2, the hole, large footpath in seal ring and axle sleeve adopts interference fit, and the external cylindrical surface of seal ring coordinates with hole, large footpath and carries out circumferential seal; When valve drive shaft moves to shift fork direction, seal ring left end face can contact with circular groove left side, and seal ring right side can contact with closure gasket groove right flank, forms the end face seal of two places; When valve drive shaft moves constantly to rocking arm direction, seal ring left side can contact with closure gasket groove left surface, and axle sleeve left side can contact with shift fork right side, also forms the end face seal of two places; By end face and circumferential common seal action, ensure that the anti-gas-leak performance that turbine box assembly is excellent.
Below in conjunction with figure and embodiment, the utility model is further described.

Embodiment
A kind of turbine box venting valve transmitting assemblies, comprises valve drive shaft 1, axle sleeve 2 and seal ring 3.
Described valve drive shaft 1 is provided with the annular seal groove 1-1 for installing seal ring 3.
The connecting part that two ends in described axle sleeve 2 are respectively equipped with diameter holes 2-1 and large footpath hole 2-2, diameter holes 2-1 and large footpath hole 2-2 is provided with circular groove 2-3.
Seal ring 3 is arranged in the annular seal groove 1-1 on valve drive shaft 1, valve drive shaft 1 is arranged in axle sleeve 2, valve drive shaft 1 adopts Spielpassung with the diameter holes 2-1 in axle sleeve 2, diameter holes 2-1 in axle sleeve 2 realizes guiding, anti-beat function, reduce axle sleeve 2 and the wearing and tearing of valve drive shaft 1 contact segment, increase the service life.Seal ring 3 adopts interference fit with the large footpath hole 2-2 in axle sleeve 2, and the external cylindrical surface of seal ring 3 coordinates with large footpath hole 2-2 and carries out circumferential seal.
The quantity of described seal ring 3 is two, and the end face of two seal rings fits tightly.
Sketch application of the present utility model: axle sleeve 2 interference fit is fixed on turbine box 4, valve drive shaft 1 one end is connected with shift fork 5, and utilize circular groove 2-3 left side 2-3-1 to coordinate with seal ring 3 left side, play the effect that assembling is spacing, be convenient to shift fork 5 assembling and positioning, valve drive shaft 1 the other end is connected with rocking arm 6.Shift fork 5 is for controlling the opening and closing of venting valve, and 6, rocking arm is connected with exhaust gas by-pass valve.Exhaust gas by-pass valve controls the opening and closing of venting valve indirectly by rocking arm 6, valve drive shaft 1 and shift fork 5.
When valve drive shaft 1 moves to shift fork 6 direction, seal ring 3 left end face can contact with circular groove 2-3 left side 2-3-1, and seal ring 3 right side can contact with closure gasket groove 1-1 right flank 1-1-2, forms the end face seal of two places; When valve drive shaft 1 moves constantly to Rocker arm 5 direction, seal ring 3 left side can contact with closure gasket groove 1-1 left surface 1-1-1, and axle sleeve 2 left side can contact with shift fork 6 right side, also forms the end face seal of two places; By end face and circumferential common seal action, ensure that the anti-gas-leak performance that turbine box assembly is excellent.
