Abstract

The utility model discloses a retarder impeller and relates to automotive auxiliary brakes, in particular to a rotor impeller of an automotive retarder, which comprises an annular impeller plate (10). An annular groove (11) is reserved on the upper surface of the impeller plate (10), and the bottom of the annular groove (11) is in a semicircular structure. Slanting radiating fins (12) are distributed in the annular groove. The impeller plate (10) is integrated with the slanting radiating fins (12). Ribs (13) which are arc-shaped are radially distributed on the back of the impeller plate (10), and all the ribs are inclined in the same peripheral direction. By the retarder impeller, the problem that the existing retarder impeller is short in service life and poor in radiating performance is solved.

Description

The retarder impeller

Technical field

The utility model relates to the automobile additional brake, is specifically related to the rotor wheel of automobile retarder.

Background technology

Current vortex retarder is a kind of auxiliary brake device for automobile, is commonly called as electricity and stops.This device generally is installed between automobile drive axle and the change speed gear box, realizes the no touch braking through electromagnetic induction principle.It is a kind of auxiliary braking system, is a necessary complement of brake system, but can not replaces primary brake system.

Retarder has been widely used on the large and medium-sized vehicle as a kind of complemental brake system.Retarder is made up of parts such as stator impeller, rotor wheel, H Exch, controllers; Wherein rotor wheel is in the high-speed operation when retarder is worked always; Its requirement of strength is also very high, thereby the performance of rotor wheel improves the overall performance that can directly improve retarder.

Existing retarder impeller exists service life short, the shortcoming that heat dispersion is bad.

Summary of the invention

The utility model provides a kind of retarder impeller, and the utility model has solved existing retarder impeller and existed service life short, the problem that heat dispersion is bad.

For addressing the above problem; The utility model adopts following technical scheme: the retarder impeller; Comprise the impeller plate 10 of annular, impeller plate 10 upper surfaces have annular groove 11, and annular groove 11 bottoms are semicircular structures; Be distributed with inclination radiating gill 12 in the annular groove 11, impeller plate 10 is structure as a whole with inclination radiating gill 12; Impeller plate 10 back sides are provided with the rib 13 that radially distributes, and said rib 13 is arcs, and all ribs 13 are obliquely installed to same circumferencial direction.

The utility model retarder impeller has long service life, good heat dissipation effect, basic maintenance free advantage.

Nomenclature among the figure: impeller plate 10, annular groove 11, inclination radiating gill 12, rib 13.

The specific embodiment

With illustrated embodiments the utility model is done detailed explanation below.

Shown in Fig. 1-4, the retarder impeller comprises annular impeller plate 10, and impeller plate 10 upper surfaces have annular groove 11, and annular groove 11 bottoms are semicircular structures, are distributed with inclination radiating gill 12 in the annular groove 11, and impeller plate 10 is structure as a whole with inclination radiating gill 12; Impeller plate 10 back sides are provided with the rib 13 that radially distributes, and said rib 13 is arcs, and all ribs 13 are obliquely installed to same circumferencial direction.

The current vortex retarder impeller of the utility model adopts alloy material and advanced precision cast forming process casting to form; The high-temperature behavior of material is high, and the heat radiation angle and the structure of the radiating gill of impeller are all passed through the finite element design, and ventilation volume is big; Good heat dissipation effect, maintenance free basically.

What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.

Claims

1. the retarder impeller is characterized in that, comprises the impeller plate (10) of annular; Impeller plate (10) upper surface has annular groove (11); Annular groove (11) bottom is a semicircular structure, is distributed with inclination radiating gill (12) in the annular groove (11), and impeller plate (10) is structure as a whole with inclination radiating gill (12); Impeller plate (10) back side is provided with the rib (13) that radially distributes, and said rib (13) is an arc, and all ribs (13) are obliquely installed to same circumferencial direction.
