Abstract
The utility model relates to a novel automobile-use electromagnetic retarder. A controlling system comprises a supporting frame (5), a master switch (3) and a coupling (7), and the coupling is connected with an automobile driving axle. The utility model is characterized in that the coupling is provided with a rotor (2) having an impeller, a stator coil (1) is arranged on the supporting frame, the two ends of the stator coil are provided with magnetic pole conducting boards (6), and the stator coil is electrically connected with the master switch through a controlling box (4). The utility model designs the brake auxiliary device of the motor vehicle by utilizing the electromagnetic theory, so as to realize the non-contact vehicle brake retarding and to reduce the action time of the brake, thereby the service life of the braking system is prolonged, and the effectiveness of brake is improved, in addition, different gears can be chosen according to the condition to generate different braking torque, therefore, the driving safety is greatly improved.
Description
Technical field: the utility model relates to a kind of retarding device, the spy about motor vehicle braking systems
What do not relate to is a kind of contactless retarding device, and what be specifically related to is a kind of electromagnetic principle that utilizes
Produce the retarding device of lock torque.
Background technology: in the prior art, self-propelled vehicle generally all adopts brake system of car or hydraulic brake system to realize the reduction of speed braking by the rigid obvolvent generation friction force of brake facing.Because these all belong to the contact mechanical braking, very easily cause very high temperature rise, therefore its service life is short, its serviceability reduces because of increasing of its friction lining access times, thereby usually need renewal of facing, bring danger for travelling of vehicle, also make troubles simultaneously to chaufeur.
Summary of the invention: in view of the problem that known technology exists, the purpose of this utility model aims to provide a kind of knot
The structure science, stable and reliable for performance, can reduce the braking number of times, reduce the temperature rise that braking produces, carry
The contactless later-model automobile electromagnetic of high brake system service life and travel safety is slow
Device.For achieving the above object, the utility model is finished as follows: this later-model vapour
Automobile-used electromagnetic retarder, its control system includes support, cabinet switch and coupler, and is described
Coupler is connected with propeller-shaft, it is characterized in that described coupler is provided with the commentaries on classics of band impeller
Son is provided with stator coil on described support, the two ends of described stator coil are provided with leading pole
Plate, described stator coil is electrically connected with cabinet switch by control capsule; Described support is provided with newspaper
Alert sensor; In order to the induction collision alarm, be provided with control circuit in the described control capsule, this control
Circuit is used for the size of control brake moment.The of the present utility model design successfully changed at one stroke
Because of the frequently braking by mechanical braking sytem shortens the service life of brake system, and utilize
Electromagnetic principle realizes reducing the action frequency of brake system, reduces its temperature rise to reach, and improves
The validity and the traveling security of braking, new according to the utility model design motif made
The automobile electrical magnetic retarder of type will bring positive result of use and economy to auto trade
Benefit.
Description of drawings: the utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a control system scheme drawing of the present utility model.
Most preferred embodiment: accompanying drawing has been represented structure of the present utility model and embodiment, below more in conjunction with the accompanying drawings
Further describe the relevant details and the principle of work of embodiment.This later-model automobile electrical magnetic is slow
The speed device, its control system includes support 5, cabinet switch 3, control box 4 and coupler 7,
Described retarder is installed on the automobile by support 5, described coupler 7 and propeller-shaft
Connect, described coupler 7 is provided with the rotor 2 of band impeller, and the impeller on the rotor 2 is a fan
The shape blade, the temperature rise heat that the current vortex that can leave rapidly causes keeps good deceleration and stopping performance,
Be provided with stator coil 1 on described support 5, the two ends of described stator coil 1 are provided with magnetic conduction
Pole plate 6, the magnetic field that stator coil 1 energising back produces forms by magnetic conduction pole plate 6 and rotor 2
The magnetic line of force of a closure, described stator coil 1 is electrically connected by control capsule 4 and cabinet switch 3
Connect, be provided with control circuit in the described control capsule 4, this control circuit can divide many according to different situations
Plant mode, promptly realize many grades slowly, it comes down to control slowly with the size of electric current
Degree, the utility model adopt six grades slowly, select not according to the speed of a motor vehicle, road conditions, load-carrying situation
Same gear produces different lock torques, carries out slow formula braking effectively reposefully to reach,
Described support 5 is provided with warning sensor 8, and this sensor 8 is in order to induction car chassis and not
The collision alarm of flat road surface makes chaufeur can in time take safety method; On the vehicle steering
Control circuit in master cock (not shown) and the control capsule 4 is electrically connected, because the effect of control capsule 4 inner control circuits makes automobile can not produce acceleration/accel when descending, and the maintenance constant speed drive.In a dust boot, the inside is marked with efficient lubricant oil to the utility model the bearing felt of transmission shaft, self-lubricating for a long time.When the utility model is worked, press cabinet switch 3, stator coil 1 energising, stator coil 1 produces magnetic field, the rotation of propeller-shaft, the rotor 2 that drives coupler 7 and be connected with coupler rotates, and rotates cutting magnetic line in the magnetic field that stator coil 1 produces, so produce current vortex in rotor 2, thereby produce a lock torque opposite with the transmission shaft hand of rotation, under the effect of moment, the propeller-shaft rotating speed descends rapidly, and realizes the purpose of gradual braking.
