Abstract
The utility model relates to a hub type retarder with adjustable exciting gap. The hub type retarder comprises a stator assembly and a tubular rotor sleeved on the external periphery of the stator assembly, wherein the stator assembly comprises a radial exciting gap arranged between the stator assembly and the rotor, the rotor exciting surface forming the exciting gap adopts a conical surface, and the stator exciting surface adopts a conical surface with identical obliquity of the rotor exciting conical surface.

Because both the rotor exciting surface and the stator exciting surface adopt conical surfaces with identical obliquity, by adjusting the relative positions of the axial directions of the rotor and the stator, the rotor can further approach to the and the stator or slightly keep away from the stator, thereby the purpose of adjusting the radial exciting gap can be realized, to ensure the braking torque to be adjustable, and to ensure the matching of the hub type retarder to be more extensive.
Description
Technical field
The utility model relates to a kind of auxiliary brake of vehicle, especially a kind of hub formula retarder.
Background technology
Existing hub formula current vortex retarder is by columniform field frame assembly and be sleeved on the rotor field frame assembly periphery, that be straight cylinder shape and form, and excitation gap is radially arranged between field frame assembly and the rotor.The said stator assembly comprises connecting ring and the iron core along the circumferential direction all put at interval and be contained in magnet exciting coil on the iron core on the connecting ring outer ring surface, be provided with yoke at magnet exciting coil in the both sides of connecting ring outer ring surface circumferencial direction, be the cylinder cambered surface towards the excitation surface of rotor on all yokes, and all be in the same face of cylinder, columniform excitation surface is that rotor inner surface does not contact on yoke and the rotor, has formed excitation gap radially between the two.At present, the excitation gap of hub formula retarder only is 0.8～1mm, and when mounted, stator excitation surface and rotor-exciting surface are easy to collision, scratch, cause retarder impaired; In addition, by said structure as can be known, yoke and rotor are in case after producing well, the size on its excitation surface is certain, the excitation gap that has formed after having determined both to be assembled together also is constant, can not adjust, so the maximum braking moment of this structure retarder also can not be adjusted; Moreover rotor adopts straight cylinder shape, the flange-cooled structure of outer surface, and the casting technique performance is not good, is unfavorable for withdrawing pattern, as adopts full finished surface, and then its cost will greatly improve.
Also having a kind of in the hub formula retarder is permanent-magnet buffer, this retarder is with iron core and magnet exciting coil in the permanent magnet replacement current vortex retarder, other structures and current vortex retarder are basic identical, and there are the problems referred to above of current vortex retarder equally in permanent-magnet buffer.
The utility model content
The purpose of this utility model provides a kind of excitation adjustable gaps, hub formula retarder easy for installation.
To achieve these goals, the utility model adopts following technical scheme: the hub formula retarder of excitation adjustable gaps, comprise field frame assembly and the cylindrical rotor that is sleeved on the field frame assembly periphery, field frame assembly comprises the excitation gap that has between field frame assembly and the rotor radially, the rotor-exciting surface that forms the excitation gap is a taper seat, and the stator excitation surface is and the taper seat of rotor-exciting taper seat with gradient.
Be the circular cone cambered surface identical with rotor-exciting taper seat gradient towards the surface of rotor-exciting taper seat on each yoke in the field frame assembly, the circular cone cambered surface of all yokes all is on the same taper seat, formation stator excitation taper seat.
The gradient of the relative rotor axis of rotor-exciting taper seat bus is 2 °-5 °.
The gradient of the relative rotor axis of rotor-exciting taper seat bus is 3 °.
Described cylindrical rotor is the uniform taper barrel of circumferential wall thickness, along the circumferential direction is evenly equipped with fin on the conical outer surface of rotor.
Described cylindrical rotor is the uniform taper barrel of circumferential wall thickness, along the circumferential direction is evenly equipped with fin on the conical outer surface of rotor.
Described cylindrical rotor is the uniform taper barrel of circumferential wall thickness, along the circumferential direction is evenly equipped with fin on the conical outer surface of rotor.
When the utility model is installed and used on vehicle, rotor is fixedly connected on the output shaft of vehicle gear box or on the power shaft of vehicle rear axle by the rotor terminal pad, field frame assembly is fixedly connected on the bearing pedestal or rear end cap of gearbox or back axle by the stator terminal pad, because forming radially, the rotor-exciting surface and the stator excitation surface in excitation gap are the taper seat with gradient, so change the relative position of rotor and stator shaft orientation by the axial width of adjusting the shim pack of installing between rotor and the rotor terminal pad, make the two further near or do a little away from, just can realize adjusting the radially purpose in excitation gap, it is adjustable to reach braking moment, makes hub formula retarder coupling more extensive.By reducing the thickness of shim pack, can reduce radially excitation gap, thereby realize increasing maximum braking moment; Otherwise the thickness of increase shim pack can increase radially excitation gap, to realize reducing maximum braking moment.In addition, the taper seat that cooperates between rotor and yoke has the self-centering function, and be installed the starting stage, the small end head of field frame assembly assembles the macropore of rotor, make the primary clearance between field frame assembly and the rotor can reach 3～5mm, so easy installation and reliable, the excitation surface of easy damaged rotor and stator not.When the taper barrel rotor made casting, casting external mold, core went mould convenient, and the foundry goods forming degree is good, surface quality height, and the fin of rotor outer surface casting together, and fin is evenly complete, and the surface need not Milling Process again, has reduced processing cost.
