Abstract
The utility model discloses a mounting structure for an eddy current brake; the eddy current brake comprises stator frame, a rotor, an electrode plate and a stator, wherein the stator is fixed on a stator frame, the stator frame is fixed on the bearing block of the main reducing gear of a vehicle rear axle, and the rotor is fixed on the output shaft of the main reducing gear. The rotor is a disc-type single rotor. A rear axle flange is fixedly connected with the output shaft of the main reducing gear, and the rotor is fixed on the rear axle flange. In the mounting structure, the eddy current brake is integrally combined with the vehicle rear axle, the stator and the stator frame adopt integral structure to be directly mounted on the bearing of the rear axle main reducing gear, the rotor is mounted on the output shaft of the main reducing gear, so the mounting structure for the eddy current brake is compact, reduces the axial mounting size and is applicable to urban public buses.
Description
Technical field
The utility model relates to a kind of car deceleration device, specifically relates to a kind of mounting structure of electric eddy speed reducing device.
Background technology
In the development of Hyundai Motor, more and more higher to driving safety, economy, the feature of environmental protection and the riding comfort requirement of automobile, increasing palace car, urban bus and heavy truck are equipped with the current vortex retarder as auxiliary braking system.In the prior art, the current vortex retarder that is installed on the automobile mainly contains three kinds of forms: the drum-type retarder of single rotor, be installed in two-spool disc type retarder on speed changer or the back axle, be installed in the birotor disc type retarder (its mounting means is mainly and is installed between the power transmission shaft) of small-sized front-mounted engine.The shortcoming of using existence more than is installed is: the drum-type retarder heat fading of single rotor is fast, the braking moment deficiency; Rotor moment of inertia is big, causes noise big, is installed on the back axle and can causes damage to back axle, can increase the oil consumption of vehicle.The shortcoming of two-spool disc type retarder is: 1, make complexity, cost height; 2, excessively face is more, and manufacturability is relatively poor, the cost height; 3, difficulty is installed, intensity is big; 4, part is more, and weight is big; 5, the size of An Zhuaning is bigger, and the size of power transmission shaft needs to shorten; 6, connection too much is installed, and is subjected to the influence of transmission main shaft play, fail safe is relatively poor.And three passenger vehicles that are applicable to front-mounted engine of mode, for rear-engine bus is inapplicable in the market.
Summary of the invention
The technical problems to be solved in the utility model is the mounting structure that proposes a kind of current vortex retarder of easy for installation, less installation intermediate link.
Technical problem of the present utility model is achieved by the following technical programs.
In the mounting structure of this current vortex retarder, described current vortex retarder comprises rotor frame, rotor, battery lead plate, stator, described stator is fixed on the rotor frame, described rotor frame is fixed on the bearing pedestal of automobile axle main reducing gear, and described rotor is fixed on the output shaft of main reducing gear.
Preferably, in the mounting structure of above-mentioned current vortex retarder, described rotor is the disc type single rotor.
Further, in the mounting structure of above-mentioned current vortex retarder, the output shaft that is provided with back axle flange and main reducing gear is connected and fixed, and described rotor is fixed on the back axle flange.
Described back axle flange is sleeved on the output shaft of main reducing gear, and fastening by shaft end nut.
Be compared with the prior art, the beneficial effect that the utility model had is: current vortex retarder and automobile axle integral body are combined, stator and rotor frame adopt monolithic construction, be directly installed on the rear-end gear reduction bearing pedestal, rotor is installed on the output shaft of main reducing gear, compact conformation is applicable to the installation on the urban public traffic vehicles.Adopt the disc type single rotor, shortened axial installation dimension.This mounting structure need not change original structure of vehicle and size, fixing link in the middle of not only can reducing, make the installation dimension minimum, it is maximum that the size of power transmission shaft keeps---this on the vehicle of rear-engine by being important, this is because the power transmission shaft of this form vehicle is shorter, and the weight that vehicle is increased is the lightest, and the rotor moment of inertia minimum guarantees the fail safe of using.
Description of drawings
Fig. 1 is the Facad structure figure of embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
The mounting structure of a kind of current vortex retarder as shown in Figure 1 and Figure 2 is used for the city bus assisted deceleration.Current vortex retarder comprises stator 1, rotor frame 2, battery lead plate 7, rotor 8.Stator 1 comprises electronics iron core and stator coil, is fixed on the rotor frame 2.Rotor 8 is the disc type single rotor.
The main shaft 6 of automobile main reducer is supported on the bearing pedestal 4 by bearing 5.Rotor frame 2 is fixed on the bearing pedestal 4 of vehicle main retarder by frame fixation bolt 3.Be provided with back axle flange 10, back axle flange 10 suits are fixed on main shaft 6 axle heads, and are fastening by shaft end nut 11.Rotor 8 is fixed on the back axle flange 10 by rotor set bolt 9.
Because stator and rotor frame 2 are an integral body, make syndeton more simple and reliable, adopt the disc type single rotor, shortened axial installation dimension, be applicable to the vehicle of engine at extreme rear formula.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
