Description
Technical field
The utility model relates to the improvement invention of retarder, particularly a kind of improvement invention that blocks electric eddy current rail brake for vehicle.
Background technology
In the prior art, volume and the weight of retarder are larger, and retarder is arranged on back axle or change speed gear box, to installation, makes troubles; The heat that retarder rotor produces simultaneously will pass on back axle or change speed gear box, and back axle or change speed gear box are brought to impact; It is larger that the stator of retarder produces heat when work, and lock torque decay is larger, and stability is poor.Secondly at present have the rotor portion of retarder to be connected with system of vehicle transmission rotating shaft, but its installation is not very convenient, has to be strengthened yet.Also have the bearing of the current vortex retarder that current truck uses to install very inconvenient.
Utility model content
In view of the technical matters existing in background technology, the technical matters that the utility model solves aims to provide a kind of card electric eddy current rail brake for vehicle.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of card electric eddy current rail brake for vehicle, include stationary part and rotor portion, described stationary part is arranged on support, it is characterized in that: described stationary part includes reaction plate and bearing unit, described bearing unit includes integrated combination two tapered roller bearings together, the inner ring center of described bearing unit arranges rotating shaft, described reaction plate is provided with bearing seat, described bearing unit is arranged in bearing seat, described rotor portion includes front rotating disk and rear rotating disk, and described rotating shaft is connected with rear rotating disk with front rotating disk respectively.
In described stationary part, be provided with 8 magnetic cores, 16 excitation coils, described reaction plate is connected with vehicle crossbeam with cushion rubber by support.
Locate by the bearing cap shim on bearing seat described bearing unit outer ring.
Described front rotating disk is connected with system of vehicle transmission rotating shaft respectively with rear rotating disk.
Described two tapered roller bearings are arranged in the outer ring of bearing unit and are provided with combination oil seal, the concentricity axle setting of described two tapered roller bearings, and described bearing unit is also provided with pad, is provided with the grease of lubricated use in bearing unit.
The beneficial effects of the utility model are, compare the retarder being arranged on back axle or change speed gear box, this type retarder is directly installed in system of vehicle transmission rotating shaft, installs fairly simple, only retarder support is fixed on above vehicle crossbeam, front and back rotating disk is connected with drive shaft; And only need bearing unit integral body to be pressed into bearing saddle bore while installing, bearing inner ring arranges nut and twists and compress, and installation is by convenient; Also have this retarder non-maintaining in 3 years ' operation or 500,000 kilometers on vehicle, greatly increase the maintenance cycle of retarder bearing, cost-saving, so the utility model compared with prior art has substantive distinguishing features and progress.
Accompanying drawing explanation
Details and the principle of work of embodiment of the present utility model and embodiment are described below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is C-C cutaway view in Fig. 1.
The specific embodiment
Referring to accompanying drawing, a kind of card electric eddy current rail brake for vehicle in present embodiment, include stationary part and rotor portion, described stationary part is arranged on support, described stationary part includes reaction plate 1 and bearing unit 2, described bearing unit 2 includes integrated combination two tapered roller bearings together, the inner ring center of described bearing unit arranges rotating shaft 3, described reaction plate is provided with bearing seat, described bearing unit is arranged in bearing seat, described rotor portion includes front rotating disk 4 and rear rotating disk 5, described rotating shaft 3 is connected respectively (can make rotating shaft be connected with rear rotating disk with front rotating disk respectively by butt flange) with rear rotating disk 5 with front rotating disk 4.Bearing clearance (or claim gap) presets in Bearing Factory, on retarder, does not need to adjust bearing clearance during running in bearings, and between rotor, relative position is controlled by bearing unit.In bearing unit, two tapered roller bearings are arranged in the outer ring of bearing unit and are provided with combination oil seal in both sides, the concentricity axle setting of described two tapered roller bearings, and described bearing unit is also provided with pad.Locate by the bearing cap shim on bearing seat described bearing unit outer ring.In bearing unit, be provided with the grease of lubricated use, in bearing unit, with grease, be lubricated.
In described stationary part, be provided with 8 magnetic cores, 16 excitation coils, described reaction plate is connected with vehicle crossbeam with cushion rubber by support.Described front rotating disk is connected respectively (can be in transmission connection by flange) with rear rotating disk with system of vehicle transmission rotating shaft.Compare the retarder being arranged on back axle or change speed gear box, this type retarder is directly installed in system of vehicle transmission rotating shaft, installs fairly simplely, only retarder support is fixed on above vehicle crossbeam, and front and back rotating disk is connected with drive shaft.And only need bearing unit integral body to be pressed into bearing saddle bore while installing, nut is twisted and is compressed for bearing inner ring, and installation is by convenient; Because the bearing space of bearing unit presets, so without carrying out extra adjustment, convenient; Also have oil sealing and pad to be also all integrated in bearing unit, easier for installation, retarder is non-maintaining in 3 years ' operation or 500,000 kilometers on vehicle, greatly increases the maintenance cycle of retarder bearing, cost-saving.Without as in the past with two bearings that separate, middle also have a step, then two oil sealings are set, and needs to adjust bearing space, and the pad of setting up of also wanting extra is independently installed, and bothers very much.
Its principle of work be retarder rotor with under system of vehicle transmission rotating shaft, be connected, and transmission together with drive shaft, stator is fixed together by rubber cushion and crossbeam, and during retarder work, stator coil passes into electric current, and coil middle part magnetic core partly produces magnetic field, stator and rotor air gap is passed through to rotating disk in magnetic field, due to the rotation of rotating disk, in rotating disk, produce vortex flow, on rotating disk, produce heat, realize transformation of energy, the kinetic energy of vehicle is converted to heat energy.
