Embodiment
Describe the tool current vortex retarder of a kind of specific embodiment of the present invention in detail below in conjunction with accompanying drawing.Yet, the present invention should be understood as and be not limited to this execution mode described below, and the other technologies combination that technical concept of the present invention can be identical with those known technologies with other known technologies or function is implemented.
In the following description, for clear structure of the present invention and the working method of showing, to be described by all multidirectional words, but should be with Word Understandings such as 'fornt', 'back', " left side ", " right side ", " outward ", " interior ", " outwards ", " inwardly ", " axially ", " radially " for making things convenient for term, and not should be understood to word of limitation.
The object of the present invention is to provide a kind of current vortex retarder, this current vortex retarder compared with prior art, be applicable at automobile gearbox or back axle limited space, the occasion of current vortex retarder as shown in Figure 2 can't be installed, and this current vortex retarder do not use flange and power transmission shaft, reduces production costs.The current vortex retarder that goes out shown in the present comprises stator and rotor, and stator is fixed on the stator axle sleeve, and rotor is fixed on the rotor axle sleeve, connects by rolling bearing between stator axle sleeve and the rotor axle sleeve.
As shown in Figure 4, Fig. 4 is the structural representation of current vortex retarder involved in the present invention.This current vortex retarder is comprised of stator 21 and rotor 22.When current vortex retarder was worked, stator 21 produced magnetic field, and cutting magnetic line produced induced current when rotor 22 rotated, and stator 21 applies an electromagnetic force to rotor 22, thereby produced braking moment.Stator 21 is fixed together with stator axle sleeve 24, and wherein the stator axle sleeve is positioned at the inboard.Because it is one cylindrical that the shape of current vortex retarder is haply, " inboard " of indication refers to the side near this cylindrical center axle among the present invention, and " outside " refers to the side away from this cylindrical center axle accordingly.In the present embodiment, stator 21 adopts the mode of bolt and nuts to fix with stator axle sleeve 24, and in fact, those of ordinary skills should know together the mode that two parts are fixed in that also has other, such as welding.When this current vortex retarder work, stator 21 keeps relative fixing with stator axle sleeve 24.
Keep certain air gap (not shown) between rotor 22 and the stator 21.This rotor 22 fixing with rotor axle sleeve 25 on.In the present embodiment, rotor 22 adopts the mode of bolt and nuts to fix with rotor axle sleeve 25, and in fact, those of ordinary skills should know together the mode that two parts are fixed in that also has other, such as welding.This rotor axle sleeve 25 is cylindrical objects of a hollow, and cavity 26 is almost consistent with the center of this current vortex retarder.
Fig. 5 is the schematic diagram of installing and using of current vortex retarder involved in the present invention, as shown in Figure 5.The power transmission shaft 30 of the transmission mechanism of vehicle directly is installed in the cavity 26 of rotor axle sleeve 25.This power transmission shaft 30 passes through spline joint with rotor axle sleeve 25, is used for transmitting torque.Usually, this power transmission shaft 30 can also be the power transmission shaft with a universal joint 31.When the power transmission shaft 30 of this vehicle rotated, rotor axle sleeve 25 rotated thereupon, and the rotor 22 that is connected with rotor axle sleeve 25 is with respect to fixing stator 21 setting in motions, and then cutting magnetic line, produces induced current and resistive torque.
The present invention also provides another kind of execution mode.Introduction to the second execution mode please be simultaneously referring to accompanying drawing 6 and accompanying drawing 7.The structural representation of this execution mode as shown in Figure 6, Fig. 7 is the schematic diagram of installing and using of this execution mode.In the first embodiment, the conjunction plane between rotor axle sleeve 2 and the power transmission shaft 30 all is spline structure.In the second execution mode provided by the present invention, change whole splined into the part splined.As shown in Fig. 6,7, this current vortex retarder is comprised of stator 21 and rotor 22.When current vortex retarder was worked, stator 21 produced magnetic field, and cutting magnetic line produced induced current when rotor 22 rotated, and stator 21 applies an electromagnetic force to rotor 22, thereby produced braking moment.Stator 21 is fixed together with stator axle sleeve 24, and wherein the stator axle sleeve is positioned at the inboard.Different from the first execution mode is, in the present embodiment the power transmission shaft 30 of the transmission mechanism of this vehicle be not be installed on this rotor axle sleeve 25 the two ends, the left and right sides of cavity, but directly insert from an end of this rotor axle sleeve 25.And the power transmission shaft 30 of the transmission mechanism of this vehicle only has spline for part.As shown in Fig. 6,7, spline 33 only is positioned at the ectocentral part of leaning on of this power transmission shaft 30, and the benefit of doing like this is for further reducing the installation difficulty of this current vortex retarder.This current vortex retarder also comprises some sealing rings 34, is used for preventing oil leak.
Compared with prior art, current vortex retarder disclosed in this invention can be suitable for the different vehicles, and fitting limit is unrestricted, and structure is more succinct, and realizes cost and simple installation.
Described in this specification is preferred embodiment of the present invention, and above embodiment is only in order to illustrate technical scheme of the present invention but not limitation of the present invention.All those skilled in the art all should be within the scope of the present invention under this invention's idea by the available technical scheme of logical analysis, reasoning, or a limited experiment.
