Description
Technical field
The utility model relates to a kind of structure of hydrodynamic retarder, for generating braking moment by fluid.
Background technique
This retarder generally includes the rotor of retarder housing, stator and rotatably support, and wherein, retarder housing is comprised of at least two housing parts.The first housing parts is attached to rotor and is commonly referred to as rotor housing.Described housing is moulding so also, and rotor is surrounded by described rotor housing.Stator is arranged between at least two retarder housing parts by this way, make retarder housing be divided into two component area, wherein, rotor in first component region is positioned between the first housing parts and stator like this, makes braking moment from rotor, by stator, to pass at least one rotor housing parts by fluid.
What be conventionally suitable for is to construct like this hydrodynamic retarder, makes moment of torsion by fluid power from driven elementary impeller (being rotor), to be passed to fixing sencond stage impeller (also referred to as stator).
Rotor and stator form a functional unit here, and described functional unit has a common working space and described working space can be filled working medium.For example, by driving the rotor that is torsionally positioned at (transmission output shaft or the axle (cardan shaft) being indirectly connected with the driving wheel of automobile) on the axle that needs braking, make the working medium in rotor outwards accelerate to flow and enter stator, described working medium flows to inside deceleration at diameter of stator bore.
Therefore, by the shared working space of moulding, make working medium become circulation.By the circulation of such formation, torque (being also known as the braking moment of retarder here) is delivered to stator from rotor.At this, the axle deceleration that rotor slows down and is especially torsionally connected with rotor.
At this, the size of the braking moment of transmitting depends on so-called hydrodynamic retarder filling extent.At this, filling extent is divided into the state that empties that retarder fills up state (being the state that the working medium amount of maximum possible circulates in the working space of retarder) and retarder completely (there is no working medium or only have the state of given residual working medium in the working space of hydrodynamic retarder) and the marginal state that is partially filled).
This retarder is for example open in DE10 2,007 029 018A1.Described retarder comprises the rotor of retarder housing, rotor housing, stator and rotatably support.In order to make moment of torsion or braking moment be delivered to retarder housing or rotor housing from stator, arrange and clamp connection, described clamping connection is fixed in its position the stator between retarder housing and rotor housing.
This means of fixation can make the structure of retarder become simple.Stator simply clip between retarder housing and rotor housing.By the essential clamping seam of clamping action, housing parts is subject to relatively large stress at clamping point, and described stress may produce stress crack in housing parts.Especially when using cast housing parts and having casting defect in clamping point region, this clamping connection just throws into question.
Model utility content
Therefore, technical problem to be solved in the utility model is, improves the structure of retarder, to avoid occurring the problem described in background technique.
Described technical problem solves by a kind of hydrodynamic retarder, described hydrodynamic retarder is for generating braking moment by fluid, comprise retarder housing, the rotor of stator and rotatably support, wherein, described retarder housing design is at least two component types, wherein, the first housing parts is attached troops to a unit in described rotor, wherein, described stator is arranged between at least two retarder housing parts like this, make retarder housing be divided into two component area, wherein, rotor in first component region is located with respect to stator like this between the first housing parts and stator, make braking moment from rotor, by stator, to be delivered at least one rotor housing parts by fluid, according to the utility model, described stator, rotor forms a rotor set and only by the member of described rotor set, transmits braking moment in the first housing parts of rotor with attaching troops to a unit.
Thus, the speed changer after only for example passing to by described rotor set by the braking moment of fluid generation.
Rotor set forms a unit, and it can pack the second housing parts easily into is in retarder housing.Wherein, not carry-over moment of retarder housing.Compared with background technique, the load of retarder housing alleviates, because stator is just that rotor housing is connected in retarder by the first housing parts.Requirement to retarder shell construction is minimized thus, and and then reduction expense.
In a preferred form of implementation, by form fit, be connected between stator and the first housing parts and carry out moment of torsion transmission.
Can use pin to connect and set up form fit connection.But as alternative, also can use other form fit known in background technique to connect, for example tooth portion.
In addition advantageously, the stator of rotor set is connected with the mutual bolt of rotor housing, thereby forms a unit.By frictional fit, connect, on stator or rotor housing, can not produce flexural stress.In order to guarantee in tolerance range, need only process contact surface.
Stator can have at least one flange on circumference, realizes pin connection and bolt and connect in described lug area.But as alternative, stator also can have at least three part flanges on circumference, in described part lug area, respectively there is a pin to connect and be connected with bolt.
Preferably between stator and the first housing parts, Sealing is set.
Preferably, rotor set is connected with the second housing parts, wherein, described in be connected between two housing parts and realize, in other words, rotor housing is directly connected with another retarder housing parts.Because interactional all members are located relative to one another in rotor set, rotor set can be installed in retarder housing easily.
