Abstract
The utility model relates to a coil, a stator frame and a stator of an eddy current retarder. The stator comprises the stator frame and the coil, wherein the stator frame is provided with a fitting surface for assembling the coil; the coil comprises a coil frame which consists of an axial bobbin and outwards turned ribs at two ends; the rib at one end, which is fitted with the coil fitting surface, is provided with at least one bump which axially protrudes outwards; and the fitting surface is provided with a groove which is correspondingly matched with the bump. In the scheme provided by the utility model, only the bump and the groove, which form a positioning mechanism, are required to be correspondingly arranged on the coil frame and the stator frame, so that failure of the eddy current retarder caused by wear due to relative rotation of the coil during vibration of a vehicle is avoided, and stability and reliability of the eddy current retarder are improved. The bump and the groove in the scheme are extremely convenient to manufacture, machine and assemble; production efficiency is increased; and production cost is reduced.
Description
Technical field
The utility model relates to a kind of coil, stator skeleton and stator of current vortex retarder, particularly a kind of coil, stator skeleton and stator that has location structure.
Background technology
Current vortex retarder has been widely used on the various vehicles as a kind of complemental brake system.Current vortex retarder is made up of parts such as stator, rotor, controllers, and wherein stator mainly comprises coil, iron core etc.In the vibration environment of vehicle operating, coil can relatively rotate with parts such as iron core, stator skeletons, thereby causes the wearing and tearing of the enamelled wire winding of coil and lead-in wire thereof to cause the various faults of retarder.Application number is the structure in relative rotation that prevents that 200620017026 Chinese patent file has been introduced a kind of current vortex retarder coil, its main inventive point is: on the coil rack inner cylinder face that cooperates with iron core axial strip bulge is set, and offers supporting with it groove on iron core.The shortcoming of this scheme is that the groove on the iron core needs machining to finish, the manufacturing cost height; Angular position in the assembling of coil requires to guarantee directly that the angular position detent mechanism that also need increase iron core and miscellaneous part could guarantee the location of coil, therefore can further increase manufacturing cost, and can cause efficiency of assembling low.
The utility model content
The purpose of this utility model provides a kind of manufacturing, easy to assembly, and reliable and stable current vortex retarder stator causes coil problem in relative rotation in order to solve Vehicular vibration.
For achieving the above object, a kind of scheme of the present utility model is: a kind of coil of current vortex retarder, comprise coil rack, the rib that coil rack is turned up by axial bobbin and two ends constitutes, and the rib of a described end is provided with at least one vertically to the projection of outer lug.
Further, be equipped with the outer package layer that is used for surrounding described coil on two ribs of described coil rack with coil rack.
Another kind of scheme of the present utility model is: a kind of stator skeleton of current vortex retarder, stator skeleton are provided with the installation mating surface that is used to assemble coil, described installation mating surface be provided be used for coil rack on the groove of projection corresponding matching.
Another scheme of the present utility model is: a kind of stator of current vortex retarder, comprise stator skeleton and coil, stator skeleton is provided with the installation mating surface that is used to assemble coil, coil comprises coil rack, the rib that described coil rack is turned up by axial bobbin and two ends constitutes, the rib of an end that cooperates with described coil installation mating surface is provided with at least one vertically to the projection of outer lug, and the installation mating surface is provided with the groove with described projection corresponding matching.
Further, be equipped with the outer package layer that is used for surrounding described coil on two ribs of described coil rack with coil rack.
Scheme of the present utility model only needs the detent mechanism of relative set projection and groove on coil rack and stator skeleton, thereby the coil of avoiding causing in the Vehicular vibration process relatively rotates and causes wearing and tearing so that current vortex retarder to break down, and has improved the stability and the reliability of current vortex retarder.And the projection of this scheme, groove manufacturing processing, assembling are very convenient, have improved production efficiency, have reduced production cost.

Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
Coil as shown in Figure 1 and Figure 2, the stator skeleton shown in Figure 3 of packing into, assembly relation is as shown in Figure 4.
As Fig. 2, coil is made up of coil rack 1, enamelled wire winding 2, outer package layer 11, and coil inside is used to install iron core.Coil rack 1 comprises the rib that turns up at axial bobbin and two ends, and outer package layer 11 connects two ribs, with coil rack 1 seal coat envelope curve winding 2.The rib of one end is provided with vertically and can be provided with a plurality of to the projection 13(of outer lug projection).As Fig. 3, stator skeleton 3 integral body are formed by high-strength aluminum alloy die casting, be provided with altogether in a week in the installation position of eight places assemblings coil, the installation position with fitting surface that coil cooperates on be provided with the groove 31 that matches with coil rack upper protruding block 13.As Fig. 4, during the coil assembling, projection 13 on the coil rack 1 cooperates with the groove 31 of stator skeleton 3, can finish the angle positioning requirements of coil easily, prevent simultaneously relatively rotating of the coil that causes because of vibrations and iron core, stator skeleton 3 effectively, avoid causing current vortex retarder short circuit, open circuit fault because of coil weares and teares.
Coil rack is a plastic pressuring piece, and by the machine-shaping of thermoplastic general injection, the projection on its end face is by the mould straight forming; Stator skeleton is the high-strength aluminum alloy die casting, and the groove that the projection on itself and the coil is nested also is directly by the die casting moulding when stator skeleton die casting.Therefore, this projection groove detent mechanism need not additionally to increase manufacturing cost.
