Abstract
The utility model relates to a spline shaft of a hydraulic retarder. A thread connection is adopted between the spline shaft of the hydraulic retarder and a dismantling tool. One end of the spline shaft is provided with an inner thread processed on the surface of an incircle of an opening. The dismantling tool comprises a pull ring with an outer thread, and an ejector rod penetrating through a central through hole of the pull ring and then supporting against a cone shaft of an output shaft of a transmission gear. The spline shaft of the hydraulic retarder effectively solves the problem of convenience for dismantling of the spline shaft of the hydraulic retarder.
Description
Technical field
The utility model relates to a kind of splined shaft of hydrodynamic retarder.
Background technique
Advantages such as hydrodynamic retarder because its braking moment is big, does not almost have heat fade as a kind of complemental brake system, and volume is little, in light weight are widely used in all kinds of high speeds, heavy-duty vehicle in developed country.At present, domestic have only on the minority palace car use is arranged, perfect along with the brake safe rules, hydrodynamic retarder will have more wide applications.Hydrodynamic retarder is made up of parts such as retarder housing, stator impeller, impeller of rotor assemblies.Hydrodynamic retarder mainly is installed together through spline and two of gearbox outputs, and owing to the interference fit that is connected to of spline, and the vehicle bottom space is less, causes very inconvenience of hydrodynamic retarder dismounting, the maintenance difficulty.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency of the prior art and splined shaft that a kind of ability a kind of hydrodynamic retarder for convenience detach is provided.
The technical solution of the utility model is the splined shaft of said hydrodynamic retarder, comprises splined shaft, and its special way is: said splined shaft adopts between the frock with dismounting and is threaded.
As preferably: said splined shaft one end is processed with internal thread at the internal circular surfaces of its opening part.
As preferably: said dismounting frock is by offering externally threaded draw ring, penetrating the push rod that is connected in the output shaft of gear-box tap web after the said draw ring central hole and form.
Compared with prior art, the utility model has the advantages that:
⑴ on splined shaft direct machining screw, and the processing technology of part is simple, and cost is low.
⑵ improved the removal efficiency of hydrodynamic retarder greatly because splined shaft is threaded with dismantling to adopt between the frock, the maintenance of hydrodynamic retarder or change convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model hydrodynamic retarder splined shaft.
Fig. 2 be the utility model hydrodynamic retarder splined shaft with the dismounting frock between adopt the structural representation that is threaded.
Fig. 3 is the structural representation of the utility model hydrodynamic retarder.
Embodiment
The utility model below will combine accompanying drawing to do further to detail:
See also shown in Figure 1ly, splined shaft 1 one ends of said hydrodynamic retarder are processed with internal thread 11 at the internal circular surfaces of its opening part.
See also shown in Figure 2ly, said hydrodynamic retarder splined shaft 1 adopts between the frock 2 with dismounting and is threaded.Said dismounting frock 2 is by offering externally threaded draw ring 21, penetrating the push rod 22 that is connected in output shaft of gear-box 3 tap webs after said draw ring 21 central hole and form.
See also shown in Figure 3ly, said hydrodynamic retarder is by retarder lid 4, stator impeller 5 and the retarder shell 6 installed successively, wear and be installed in the splined shaft 1 that retarder shell 6 axis holes, stator impeller 5 axis holes, retarder cover in 4 axis holes and form continuously.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
Claims (3)
1. the splined shaft of a hydrodynamic retarder comprises splined shaft, it is characterized in that: said splined shaft adopts between the frock with dismounting and is threaded.
