Abstract
The utility model discloses a connecting device for a hydrodynamic retarder and a reduction gear box. The connecting device comprises a connector (4), wherein a box cover (2) of the reduction gear box is connected with an end cover (5) of the hydrodynamic retarder through the connector (4), the connector (4) is arranged between the end surface of the box cover (2) of the reduction gear box and the end surface of the end cover (5) of the hydrodynamic retarder, and the output end of a power output shaft (1) of the reduction gear box is arranged in a transmission shaft (7) of the hydrodynamic retarder and is peripherally limited; the power output shaft (1) and the transmission shaft (7) share the same axis. After the structure is adopted, as the power output shaft of the reduction gear box is directly connected with the transmission shaft of the hydrodynamic retarder, the transmission shaft at the connecting part is supported by the power output shaft, and a bearing at the end cover part of the hydrodynamic retarder in the prior art is omitted. Therefore, the connecting structure is simplified, parts are reduced, and the cost is lowered.
Description
Technical field
The utility model relates to technical field of automobile parts, is specifically the connection set of a kind of hydrodynamic retarder and speed reducer.
Background technique
Retarder is the complemental brake system for large vehicle (such as truck, passenger vehicle etc.), and its effect is to make quality not consume the energy of braking system compared with the steady deceleration of large vehicle.Hydrodynamic retarder is the one in retarder, it is again fluid power speed reducer, it drives liquid to rotate by the rotor being connected on transmission shaft, the kinetic energy of liquid is increased, then impact the blade on stator, causing kinetic energy rejection and rotating is heat energy, thereby consumes the kinetic energy of automobile, plays braking action.The hydrodynamic retarder of prior art is normally connected use with speed reducer, the pto＝power take-off of speed reducer is connected with the transmission shaft of hydrodynamic retarder by coupling.Therefore, there is following shortcoming in the connection set of hydrodynamic retarder of the prior art and speed reducer: because hydrodynamic retarder itself carrys out supporting shaft with two bearings, and this transmission shaft is connected with the pto＝power take-off of speed reducer by coupling again, therefore, this connection set complex structure, component are more, increase on the one hand cost of production, assembling trouble on the other hand, reduces manufacturing efficiency.
Model utility content
Technical problem to be solved in the utility model is, provide a kind of simple in structure, cost is low, the hydrodynamic retarder that manufacturing efficiency is high and the connection set of speed reducer.
For solving the problems of the technologies described above, the hydrodynamic retarder that the utility model provides and the connection set of speed reducer, it comprises the link that connects the case lid of speed reducer and the end cap of hydrodynamic retarder, described link is between the case lid of speed reducer and the end face of the end cap of hydrodynamic retarder, and the output terminal of the pto＝power take-off of speed reducer is positioned at the transmission shaft of hydrodynamic retarder and circumferentially spacing, the axis of pto＝power take-off and the axis of transmission shaft are same axis.
Between the pto＝power take-off of described speed reducer and transmission shaft, undertaken circumferentially spacing by flat key or spline.
Bearing (ball) cover and supplemental support flange are housed in described link, supplemental support flange is socketed in outside transmission shaft, and one end of supplemental support flange is fixedly connected with the end cap of hydrodynamic retarder, the other end close-fitting is in one end of bearing (ball) cover, and the other end of bearing (ball) cover is fixedly connected with the case lid of speed reducer.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
1) owing to the pto＝power take-off of speed reducer being directly connected in the transmission shaft of hydrodynamic retarder, the transmission shaft of this joint is provided a supporting role by pto＝power take-off, save in prior art hydrodynamic retarder at the bearing of end caps, therefore, simplify linkage structure, reduce again part, reduced cost simultaneously;
2) in addition, replace the design of coupling with link, simpler linkage structure, has also improved efficiency of assembling greatly.
