Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to the utility model.
As Figure 1-3, the utility model discloses a kind of stator pumps resistance wheel for Retarder in parallel, include
Pump resistance wheel body 1, traction grooved 4, pump blade 6, exhausting blade 8 and connection sheet 10, pump resistance wheel body 1 adopts circular-arc-shaped design, pump
The middle part of resistance wheel body 1 offers manhole 3, and outer wall offers some seal grooves 5, and traction grooved 4 is opened in circular logical
On the side wall in hole 3, pump blade 6 is obliquely installed around manhole 3 with exhausting blade 8 and hinders wheel body 1 inwall, connection sheet in pump
The 10 surrounding the week side of boss being arranged at pump resistance wheel body 1.
Pump blade 6 have 16 groups, exhausting blade 8 have 1 group, be all obliquely installed in pump hinder wheel body 1 inwall, with pump hinder wheel body
The angle of 1 inwall is 49 °, hinders wheel body 1 using reinforcement and pump and is fixedly connected, on pump blade 6, interval offers square oil-feed
Hole 7, pump resistance wheel body 1 offers circular oil outlet 2, and square fuel feed hole 7 and circular oil outlet 2 form circulating oil path, exhaust
Steam vent 9 is offered on the side of blade 8 and communicates with pump resistance wheel body 1 surface.
Operation principle:
The application stator pumps resistance wheel, pump resistance wheel body 1 profile adopts circular-arc-shaped design, is easy to form one with impeller pump driving wheel
Individual working chamber, uniform force, structural strength is high；Traction grooved 4 is mainly used in drawing the hydraulic medium oil rotating with blade, so that
Do not have the direction that the Medium Oil of blade-section flows because not having blade chaotic it is ensured that there is no the local Medium Oil of blade and having leaf
Medium Oil at piece rotates together, makes the oil circulation of Medium Oil reach optimum state；Pump blade 6 has 16 groups and is distributed evenly over
Form 47 degree to 50 degree angles, this blade can be increased in the form of reinforcement in designed circular arc working chamber and with direction of rotation
Plus circular arc spherical intensity, more importantly drive retarder oil circulation, producing resistance to impeller pump driving wheel makes car deceleration.
Square fuel feed hole 7 on pump blade 6 is molded by rough-cast, and casting accuracy is high, smooth surface, smooth surface
Be conducive to the flowing of retarder Medium Oil, reduce the loss of idle work, compared with existing like product, in the application, oil-feed is square
Hole 7 quantity reduces 4 to 6, because the Medium Oil that the working chamber being formed with impeller pump driving wheel is taken turns in stator pumps resistance passes through impeller pump
Driving wheel high-speed rotation, stator pumps resistance wheel constitutes a circle and 47 to the 50 little working chambers of degree with the pump blade 6 of impeller pump driving wheel,
In the little working chamber of this pump blade 6 composition, moment defines spiral toroidal vortex flow, the quality that spiral toroidal vortex flow is formed
Directly affect the size to impeller pump driving wheel resistance, oil-feed square opening 7 quantity, be unfavorable for that spiral toroidal vortex flow is formed more, pass through
Research experiment reduces oil-feed square opening 7 quantity, increases oil-feed square opening 7 area and improves oil-feed square opening 7 smoothness and subtract
Few oil-feed square opening 7 deflection can meet retarder oil inlet quantity and increase retarder moment, improve the deceleration energy of car further
Power, improves oil gas and combines the using effect of hydraulic retarder it is ensured that the life of all riders and driver and property are pacified
Entirely.
The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not
It is confined to this, any those familiar with the art, in the technical scope that the utility model discloses, can readily occur in
Change or replacement, all should cover within protection domain of the present utility model.
