Abstract
The utility model relates to a connection structure of a single-turnplate eddy current retarder and a gearbox. The eddy current retarder comprises a stator frame, a plate electrode, and a disc-type single rotor, an iron core and a coil are fixed on the stator frame, the stator frame is fixed on a rear end cover of the gearbox, and the disc-type single rotor is fixed on an output flange of the gearbox. The rear end cover of the gearbox is provided with a screw hole and a seam allowance, and the stator frame and the rear end cover are fixed by bolts. According to the utility model, the stator of the eddy current retarder and the rear end cover of the automobile gearbox are directly connected, the rotor is mounted on an output flange of a main reducing gear, the structure is compact, and a transmission shaft is directly connected with the flange of the gearbox, so the length of the transmission shaft is not shortened while the retarder is mounted. The connection structure of single-turnplate eddy current retarder and a gearbox is particularly suitable for a small-sized automobile with a rear engine, and the retarder in the structure is lighter in weight than a retarder in a double-turnplate structure and the like.
Description
Technical field
The utility model relates to a kind of car deceleration device, specifically relates to the syndeton of a kind of single rotating disk current vortex retarder and gearbox.
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 Double-rotor disc retarder (its mounting means is mainly and is installed between the power transmission shaft) of small-sized front-mounted engine.The shortcoming that exists is used in above installation: the drum-type retarder heat fading of single rotor is fast, and braking moment is not enough; Rotor moment of inertia is large, causes noise large, and being installed on the back axle to the back axle injury, can increase the oil consumption of vehicle.The shortcoming of two-spool disc type retarder is: 1, make complexity, cost is high; 2, excessively face is more, and manufacturability is relatively poor, and cost is high; 3, difficulty is installed, intensity is large; 4, part is more, and weight is large; The size of 5, installing is larger, and the size of power transmission shaft needs to shorten; 6, connection too much is installed, and is subjected to the impact of transmission main shaft play, fail safe is relatively poor.And mode three is only applicable to the passenger vehicle of front-mounted engine, 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 syndeton of current vortex retarder in vehicle that proposes a kind of easy for installation, less installation intermediate link.
Technical problem of the present utility model is achieved by the following technical programs.
In the syndeton of this single rotating disk current vortex retarder and gearbox, described single rotating disk current vortex retarder comprises rotor frame, battery lead plate, disc type single rotor, described rotor frame is fixed on the rear end cap of gearbox, and described rotor is fixed on the output flange of gearbox.
The rear end cap of described gearbox is provided with screw and seam, and described rotor frame and rear end cover bolt are fixed.
The screw of the rear end cap of described gearbox and seam are the integrative-structure of global formation.
Described rotor is fixed on the flange of output shaft of gearbox.
Be compared with the prior art, the beneficial effect that the utility model has is: with current vortex retarder and the whole combination of automobile gearbox, stator is directly installed on the gearbox rear end cap, rotor is installed on the output shaft flange of main-gear box, compact conformation, power transmission shaft directly is connected with the flange of speed changer, does not therefore shorten propeller shaft length because retarder is installed, the vehicle that is particularly useful for small-sized rear engine also has the retarders such as retarder weight ratio double disk structure of this structure light.Adopt the disc type birotor, shortened axial installation dimension.This mounting structure need not change the original structure of vehicle and size, fixing link in the middle of not only can reducing, so that installation dimension is minimum, the size of power transmission shaft keeps original length---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 rotor moment of inertia is minimum, guarantees the fail safe of using.

Fig. 2 is the left 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 commerial vehicle assisted deceleration.Current vortex retarder comprises rotor frame 4, battery lead plate 6, rotor 7.Iron core and stator coil 5 are fixed on the rotor frame 4.Battery lead plate 6 is positioned at the axial sides that stator coil is not installed a side of rotor frame 4, and rotor 7 is the disc type single rotor, near battery lead plate 6, is the air gap, magnetic field between rotor 7 and battery lead plate 6 are axial.
The rear end cap 1 of automobile gearbox is provided with screw and seam 3, global formation processing on this screw and the seam rear end cap.Rotor frame 4 is fixed on screw and the seam 3 by four bolts 2.
Be connected with output flange 9 on the output shaft 8 of automobile gearbox, rotor 7 is fixed on the output flange 9 by set bolt 10.
Because rotor frame 4 directly is fixed on the gearbox rear end cap, so that syndeton is more simple and reliable, adopt the disc type single rotor, be applicable to the vehicle of engine postpositioned.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
