Embodiment
Describe the automobile retarder with spontaneous electrical function of a kind of specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.Yet, the utility model 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 utility model 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 utility model 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.In addition, employed " inboard " word one side of mainly depending on the power transmission shaft of nearly retarder in the following description; " outside " word mainly refers to the side away from the power transmission shaft of retarder.
Employed retarder is installed on the gearbox back more in the prior art, is connected with the drive system of automobile by power transmission shaft.When automobile normal running, rotor is with the power transmission shaft High Rotation Speed, owing to coil no power this moment, iron core does not have magnetic field, therefore do not produce braking moment, if coil leads to exciting curent, several iron cores just produce several magnetic fields, part magnetic flux by iron core increases, and the part magnetic flux that leaves iron core reduces, and produces current vortex in the rotor thereby make, the rotor of current-carrying is subject to the effect of power in magnetic field, its action direction is opposite with the direction of rotation of rotor, hinders the rotation of rotor, thereby makes current vortex retarder produce braking moment.This shows that the size that produces braking moment in the retarder depends mainly on the exciting curent by coil, perhaps the speed of rotor rotation.Exciting curent in coil is larger, and perhaps the speed of rotor rotation is larger, and the braking moment that produces is just larger.
Therefore this retarder is forced kinetic moment in order to provide in the prior art, and the volume and weight of retarder is usually all very huge and heavy, also therefore causes making the with high costs of this retarder, and the restriction retarder is used in more place.
The purpose of this utility model is to provide a kind of new retarder that is used for facilities for transport and communication, comprise: the first rotor of retarder power transmission shaft, described the first stator outside of the first stator and position, wherein, this retarder power transmission shaft is by the power transmission shaft coupling of a gear unit and these facilities for transport and communication.
As shown in Figure 2, Fig. 2 is the structural representation of the shown retarder of the utility model.Among Fig. 2 22 is power transmission shafts of automobile or other Large-sized Communication transporting equipments.One end of power transmission shaft 22 is connected with a gear 12, drives this gear 12 and rotate synchronously when power transmission shaft 22 rotates.Gear 12 and gear 11 couplings, and gear 11 is connected with the power transmission shaft 21 of retarder.Therefore when power transmission shaft 22 rotated, this rotating torque was transferred into the power transmission shaft 21 of gear 12, gear 11 and retarder from power transmission shaft 22.In the utility model, the number of teeth of design gear 12 is greater than the number of teeth of gear 11, so the power transmission shaft 21 of retarder can obtain than retarder 22 rotating speed faster, so just can be in the situation that do not increase exciting curent in the coil, accelerate rotor speed, and then increase the braking moment of retarder.Therefore also can be with this retarder volume-diminished, weight saving, and then reduce the manufacturing cost of this retarder.
This retarder is comprised of stator and rotor equally.Wherein when the power transmission shaft 21 of retarder rotated, position of stator was fixed, and rotor rotates.The structure of this retarder sees also Fig. 3.As shown in Figure 3, Fig. 3 is one of execution mode of the shown retarder of the utility model.Retarder power transmission shaft 21 is positioned at the center, and fixing with this retarder power transmission shaft is rotor, and what be positioned at internal rotor is stator.This rotor is comprised of two pawl utmost points 22,23 up and down.The structure of the dewclaw utmost point 22 and lower jaw polar 23 is similar, is staggeredly placed each other.The dewclaw utmost point 22 is consistent with the quantity of lower jaw polar 23, is generally 6 pairs or 8 pairs.Be positioned at the extremely inner stator (not shown) that is comprised of coil of pawl, when the coil electricity of this retarder, produce the magnetic line of force around the coil, the pawl utmost point is cutting magnetic line with the rotation of power transmission shaft 21, and then the generation braking moment.
Because adopt the mode of gears, its rotating speed of the shown retarder of the utility model is far longer than the rotating speed of retarder of the prior art.Therefore when the dewclaw utmost point 22 and lower jaw polar 23 rotation at full speed, can produce a huge centrifugal force, cause the dewclaw utmost point 22 and lower jaw polar 23 that deformation occur.For solving this technical problem, this retarder also arranges a support ring 24.This support ring 24 is positioned at the inside of the dewclaw utmost point 22 and lower jaw polar 23, can make on the one hand the dewclaw utmost point 22 and lower jaw polar 23 relative positions keep fixing, overcomes on the other hand because the adverse effect that centrifugal force brings.
This support ring 24 is made by non-magnet material, is preferably a stainless steel ring.The dewclaw utmost point 22 and lower jaw polar 23 all are welded on this support ring 24.
In order further to strengthen the braking moment of this retarder, the utility model provides the second execution mode, as shown in Figure 4.This retarder is comprised of the retarder of two the first execution modes.This retarder comprises a power transmission shaft 21 equally, and what be connected with this power transmission shaft 21 is the first pawl utmost point, 22, the second pawl utmost points, 23, the three-jaw utmost points 27, the four paws utmost point 26.The rotor of retarder above wherein the first pawl utmost point 22 and the second pawl utmost point 23 consist of, the rotor of retarder below the three-jaw utmost point 27 and the four paws utmost point 26 consist of.The first pawl utmost point 22 and four paws electrode structure are identical, and its placement location is the mirror image symmetry.The second pawl utmost point 23 and the three-jaw utmost point 27 structures are identical, and its placement location is the mirror image symmetry.When power transmission shaft 21 rotation of this retarder, above the rotor of retarder and the rotor of following retarder turn round with identical angular speed.On the three-jaw utmost point 27 and the four paws utmost point 26 same fixing and the support ring 28.
Because the operation principle of retarder is that kinetic energy is converted to heat energy, so retarder can produce a large amount of heat in use.For avoiding heat to continue to be gathered in automotive interior, the arranged outside one water-cooled chamber 40 of this retarder.These water-cooled chamber 40 inside arrange some passages, and other cooling fluids such as water can flow in passage, and the form by heat exchange makes this retarder cooling.
Further, also connect a generator 50 on the power transmission shaft 21 of this retarder, utilize the same rotating speed of same power transmission shaft 21 to drive this generator 50 runnings, this generator 50 provides exciting curent for retarder, can further increase the electricity generate function of this retarder, to reduce the dependence to the car load electricity needs.
Described in this specification 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.
