Abstract

This utility model discloses a double-hub electron-magnetic retarder, which comprises a stator assembly (8) and a rotor assembly (4); wherein the stator assembly (8) and the rotor assembly (4) work together. A coil pack (2) is arranged on the coil support of the stator, a magnetic core (3) is arranged on a coil support (1) located in the coil pack (2), and a magnetism isolating plate (5) is arranged between the coil pack (2) and the coil support (1) while the rotor together with a rotor outer ring (6) and a rotor inter ring (7) are often casted into one body. Compared with the present hub-rotor electron-magnetic retarder, this utility model, the double-hub electron-magnetic retarder, is characterized in that the performance of this model is more reliable and stable, and this model has a longer service life by giving a nearly thirty-percent increase to the brake torque of the retarder.

Description

The Double hub type current vortex retarder
Affiliated technical field
The utility model relates to auto parts and components, is specifically related to a kind of structure of Double hub type current vortex retarder.
Background technology
Existing hub formula current vortex retarder all is to adopt single rotor structure standard, behind the coil electricity, two ends produce the utmost point to opposite magnetic field, and single rotor has only used magnetic field on one side to produce eddy current on rotor, thereby the generation braking moment, be not fully used in the magnetic field of the other end.
Summary of the invention
The purpose of this utility model is: a kind of Double hub type current vortex retarder is provided, avoids above-mentioned the deficiencies in the prior art part, improving braking moment about 30% on the basis of similarity condition, and stable performance, and prolong more useful life.
Technical solution of the present utility model is: this retarder is made up of field frame assembly and rotor assembly, field frame assembly and rotor assembly cooperatively interact, wherein, hookup wire coil assembly on the coil brace of stator, magnetic isolation plate is established in coil block and coil brace contact position, be positioned on the coil brace between coil block magnetic core is installed, wherein, ring cast solid in rotor and rotor exterior ring and the rotor.
Stator maintains static on back axle or gearbox rear end cap by support or flange, during the stator coil energising, rotor is along with power transmission shaft rotates, and rotor exterior ring and interior ring be cutting magnetic line simultaneously, produce eddy current at rotor exterior ring inwall and endocyclic outer wall, thereby produce plugging moment.
This Double hub type retarder is different from other hub formula retarder 2 points: 1, this retarder rotor adopts two eddy current service areas promptly to increase a torsion ring in stator interior; 2, stator structure and material are done some changes, and coil brace adopts the non-magnet material manufacturing, but are adopting permeability magnetic material with magnetic core installation place material, make the magnetic line of force by arriving ring in the rotor, form the closed magnetic line of force with adjacent windings.
The utility model Double hub type current vortex retarder is compared with existing hub formula current vortex retarder, and this retarder rotor adopts two eddy current service areas, makes full use of the magnetic field that coil produces, to reach the purpose that improves braking moment.This structure retarder braking moment improves about 30%, and stable and reliable for performance, and it is more permanent to use.
Description of drawings
Fig. 1 is the utility model Double hub type current vortex retarder structure chart.
Fig. 2 is the rotor assembly schematic diagram of Fig. 1.
Fig. 3 is the field frame assembly schematic diagram of Fig. 1.
Among the figure: 1. coil brace, 2. coil block, 3. magnetic core, 4. rotor assembly, 5. magnetic isolation plate, 6. rotor exterior ring, 7. ring, 8. field frame assembly in the rotor.
Embodiment
As shown in Figure 1, 2, 3, this retarder is made up of field frame assembly 8 and rotor assembly 4, field frame assembly 8 and rotor assembly 4 cooperatively interact, wherein, one group of coil block 2 is installed on the coil brace 1 of stator, and coil block 2 is established magnetic isolation plate 5 with coil brace 1 contact position, is positioned on the coil brace 1 of 2 of coil blocks magnetic core 3 is installed, wherein, ring 7 cast solids in rotor and rotor exterior ring 6 and the rotor.
Stator maintains static on back axle or gearbox rear end cap by support or flange, during the stator coil energising, rotor is along with power transmission shaft rotates, and rotor exterior ring and interior ring be cutting magnetic line simultaneously, produce eddy current at rotor exterior ring inwall and endocyclic outer wall, thereby produce plugging moment.
