Fig. 2 is common a kind of current vortex retarder in prior art, and this current vortex retarder is installed on change speed gear box or on back axle flange conventionally, and the connection of its outside adopts and is rigidly connected.As shown in Figure 2, this current vortex retarder comprises: rotor 1, stator 2, support 4, transmission shaft flange 5, connecting screw 6, change speed gear box output flange 7, support check screw 8, change speed gear box 9.Stator 2 is fixed on support 4, and is connected with change speed gear box 9 by support check screw 8, and rotor 1 fixes by connecting screw 6 and transmission shaft flange 5.Use the current vortex retarder of this mounting means to be applied on the longer bus of vehicle body and other passenger vehicle more.For change speed gear box bonnet, there is no retarder carriage interface or have the vehicle of power takeoff, use current vortex retarder just must change mounting means.
As shown in Figure 3, Fig. 3 is another kind of common current vortex retarder in prior art, and this current vortex retarder is installed and without being fixedly connected with change speed gear box or back axle on transmission shaft.This current vortex retarder comprises rotor 1, stator 2, transmission shaft 11 and transmission shaft butt flange 10.The transmission shaft 11 of this current vortex retarder is directly installed on by its flange 10 in the middle of vehicular transmission shaft, can under less vehicle body space, use this kind of retarder.This retarder comprises two rotors 1 that are positioned at stator 2 two ends.When this retarder work, former and later two rotors 1 rotate simultaneously, on some dillies, the rigidity of its transmission shaft is lower, because the rotor inertia of retarder rotor is large, at vehicular transmission shaft, mated not at that time the driving system vibration that can twist with retarder rotor inertia, thereby the noise producing, affect service life of vehicle riding comfort and driving system parts.
Utility model content
In order to overcome the defect existing in prior art, the utility model provides a kind of effective elimination because rotor inertia is excessive, to cause the current vortex retarder that self vibrates.
In order to realize above-mentioned utility model object, the utility model discloses a kind of current vortex retarder that is installed on vehicular transmission shaft, it is characterized in that, comprising: a stator, and for generation of a magnetic field, this stator is fixed on a stator axle sleeve; One rotor, this rotor is only positioned at a side of this stator; This rotor is fixed on this rotor axle sleeve, and this rotor axle sleeve is connected with this vehicular transmission shaft; One magnetic guiding loop, this magnetic guiding loop is positioned at the opposite side of this stator, for guiding this magnetic field.
Further, this magnetic guiding loop is connected with a stator disc.This magnetic guiding loop and a stator disc are one-body molded.This magnetic guiding loop and the welding of this stator disc or riveted joint.This magnetic guiding loop is made by permeability magnetic material, and this stator disc is made by non-magnet material.
Compared with prior art, the current vortex retarder that is installed on vehicular transmission shaft disclosed in the utility model, can effectively eliminate when vehicle speed variation travels the vibration that former and later two rotors occur; And this retarder is directly installed on the transmission shaft of vehicle, and does not need change speed gear box or back axle to be fixedly connected with, and makes can greatly increasing by range of use of this retarder.
Accompanying drawing explanation
About advantage of the present utility model and spirit, can describe in detail and appended graphic being further understood by following utility model.
Fig. 1 is the structural representation of current vortex retarder;
Fig. 2 be in prior art, be installed on change speed gear box or back axle flange on the structural representation of current vortex retarder;
Fig. 3 is the structural representation that is installed on the current vortex retarder on transmission shaft in prior art;
Fig. 4 is the structural representation of the current vortex retarder on the related transmission shaft of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe the current vortex retarder that is installed on transmission shaft of a kind of specific embodiment of the present utility model in detail.Yet, the utility model should be understood as and be not limited to this embodiment described below, and technical concept of the present utility model can be implemented with other known technologies or the combination of function other technologies identical with those known technologies.
In the following description, for clear structure of the present utility model and the mode of operation of showing, to be described by all multidirectional words, but should be by Word Understandings such as 'fornt', 'back', " left side ", " right side ", " outward ", " interior ", " outwards ", " inwardly ", " axially ", " radially " for convenience of term, and not should be understood to word of limitation.
The retarder using in prior art generally includes right two rotors of a first from left, the advantage of doing is like this to increase the heat-sinking capability of brake torque and rotor, by retarder being installed on to the space, chassis that can maximally utilise vehicle on transmission shaft, but through applicant's experimental study, the current vortex retarder being installed on transmission shaft there will be transmission inertia excessive in vehicle speed variation driving process, and causes the consequence of retarder abnormal vibrations.In order to solve this technical problem, the utility model provides a kind of current vortex retarder of single rotor.
Fig. 4 is the structural representation of the current vortex retarder on the related transmission shaft of the utility model.As shown in Figure 4, current vortex retarder provided by the utility model, is installed on transmission shaft 24.Wherein this current vortex retarder is connected with stator 20 by a stator axle sleeve 25.The two ends of this transmission shaft 24 connect respectively a flange 26.Owing to adopting the structure of single rotor 21, when the vehicle acceleration or deceleration that this retarder is installed travels, can between two rotors that simultaneously rotate, there is not the vibration occurring because inertia is excessive, therefore, when effectively containing rotor inertia, reduce the vibration that retarder self produces.
In this retarder, rotor 21 is positioned at one end of stator 20, and the other end is magnetic guiding loop 23.The stator 20 of current vortex retarder is normally wound on iron core and is made by electrified wire, therefore needs magnetic guiding loop 23 to guide to form a unimpeded magnetic circuit.A kind of embodiment that the utility model provides is, stator disc 22 adopts non-magnet materials to make, and magnetic guiding loop 23 be permeability magnetic material, then magnetic guiding loop 23 is connected with stator disc 22 with welding or the mode of riveting.In another kind of better embodiment, stator disc 22 and magnetic guiding loop 23 are made by permeability magnetic material, and are directly processed into a part, and the advantage of doing is like this to save the time of setting up cost of retarder.
Compared with prior art, the current vortex retarder that is installed on vehicular transmission shaft disclosed in the utility model, can effectively eliminate when vehicle speed variation travels the vibration that former and later two rotors occur; And this retarder is directly installed on the transmission shaft of vehicle, and does not need change speed gear box or back axle to be fixedly connected with, and makes can greatly increasing by range of use of this retarder.
Described in this specification sheets is preferred embodiment of the present utility model, and above embodiment is only in order to the technical solution of the utility model to be described but not to restriction of the present utility model.All those skilled in the art comply with design of the present utility model by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be within scope of the present utility model.
