Abstract
The utility model discloses an automotive electromagnetic speed reducer. The automotive electromagnetic speed reducer comprises a left support and a right support and is characterized in that an iron core ring and an electromagnetic iron core with an electromagnetic coil are installed inside a sealed electromagnetic iron chamber which is formed by a cylinder, a left end cover and a right end cover, wherein the iron core ring is sleeved to the middle portion of a middle transmission shaft. When an automobile is driven on a downward long slope, magnetic fields generated through the electromagnetic oil which is electrified with currents generate the electromagnetic force to the iron core ring through the electromagnetic iron core, the iron core ring which is sleeved to a middle transmission shaft is stopped from rotating along the middle transmission shaft due to the electromagnetic force, and accordingly the rotating speed of the middle transmission shaft is effectively reduced instantly and the purpose of reducing the speed of the automobile is achieved. The automotive electromagnetic speed reducer has the advantages of effectively reducing the rotating speed of the middle transmission shaft instantly due to the function of the electromagnetic force, avoiding friction coefficient and wear-resisting performance reduction caused by the over-high friction plate temperature when a brake which is used for reducing speed is used for a long time, eliminating safety risks and being good in speed reducing effect, safe and reliable and simple in structure.
Description
Technical field
The utility model relates to automobile equipment, especially relates to a kind of automobile electromagnetic retarder of automotive power transmission system.
Background technology
Existing car deceleration mode is mainly to complete by the rotating speed of control engine or the mode of braking.When fully loaded large and medium-sized automobile lower long slope of loading, driver only has the long-time pin plate that touches on the brake, by the mode of braking, carry out Reduced Speed Now, can in long friction process, cause temperature to raise fast because of brake strip like this, and friction lining exists the defect that occurs friction coefficient and wear resistance decrease because of excess Temperature, this will have a strong impact on deceleration and stopping performance, to vehicle safety travel, bring hidden danger, the lighter's automobile cannot travel, severe one car crash.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile electromagnetic retarder that slows down effective, safe and reliable, simple in structure, the interaction energy that its relies on electromagnetic force has reduced the rotating speed of transmission shaft middle effectively in moment, avoided using drg deceleration to cause friction lining excess Temperature to occur friction coefficient and wear resistance decrease because of long-time, eliminated potential safety hazard.
The purpose of this utility model is achieved in that
A kind of automobile electromagnetic retarder, comprise two of the left and right support being fixed on automotive frame, feature is: the bottom at support is fixed with cylindrical shell, the top outer wall of two end caps in left and right is arranged on the fin of cylindrical shell both sides by two of left and right bolt of cover respectively, in left and right, the centre of two end caps 4 is separately installed with a bearing, tween drive spindle is sleeved on the centre of two bearings, two of left and right bearing cap shim is arranged on the bottom outer wall of two end caps in left and right by two of left and right bolt of bearing cap respectively, and be sleeved on tween drive spindle, two bearing cap shims in left and right can cover left and right bearing respectively, two end caps in cylindrical shell and left and right are with the electromagnet chamber that forms a sealing, at inwall, the electromagnet of cylindrical shell, in chamber, are fixed with electromagnetic core, are wound with magnet coil on electromagnetic core, and iron core circle is sleeved on the centre of tween drive spindle by the steady ring on both sides, inwall at two ends, tween drive spindle left and right is respectively fixed with a spline housing, and two of left and right spline housing is connected with rear propeller shaft with the mouth of change speed gear box respectively with universal-joint.
The length in the gap between the iron core circle of peripheral electromagnetic core and centre is 0.1-5 mm.
Two supports in left and right are fixed together by pipe link.
The utility model is iron core circle to be installed in the electromagnet chamber of sealing and with the electromagnetic core of magnet coil, iron core snare is contained in the centre of tween drive spindle, like this when the large and medium-sized automobile normal running of fully loaded load, magnet coil no power, tween drive spindle high-speed operation, drives automobile to advance, when running car is during at lower long slope, the switch that driver stirs magnet coil switches on power to magnet coil, in magnet coil, pass through electric current, the magnetic field that magnet coil produces produces electromagnetic force through electromagnetic core to iron core circle, this electromagnetic force is because the gap location of the magnetic field that magnet coil produces between the end face of electromagnetic core and the end face of iron core circle occurs the two poles of the earth, magnetic field and form, the iron core circle that this electromagnetic force is sleeved on obstruction on tween drive spindle rotates with tween drive spindle, thereby can effectively reduce the rotating speed of transmission shaft middle in moment, reach the object that makes car deceleration, owing to not needing to adopt drg to carry out Reduced Speed Now, avoided because of long-time use drg to slow down to cause friction lining excess Temperature occur friction coefficient and wear resistance decrease problem, also eliminated potential safety hazard, and increased the performance of drg.
Therefore, the utlity model has the interaction energy that relies on electromagnetic force has effectively reduced middle the rotating speed of transmission shaft in moment, has avoided because the deceleration of long-time use drg causes friction lining excess Temperature to occur friction coefficient and wear resistance decrease, advantage effective, safe and reliable, simple in structure eliminates safe hidden trouble, slows down, the utility model both can be used separately, also can jointly use with drg.
