Abstract
The utility model discloses a reducer comprising a stator and a rotor, wherein the stator is fixed on a framework which is fixed and arranged on a car chassis, the stator is provided with a permanent magnet with poles in staggered form. The rotor is fixed on a transmission shaft in which a coil winding is provided. The reducer adopts the permanent magnet to replace a magnetic coil in the prior art to generate the working magnetic field, the weight is light, and the permanent magnet avoids consuming the electric energy to generate the magnetic field, therefore, the electric power consumption is little; at the same time, the coil winding is used in the stator, the inductive loop of the rotor is increased, the brake moment is enlarged further, thereby strengthening the brake performance of the reducer.
Description
Technical field
The utility model belongs to the automobile brake complemental brake system, relates to a kind of retarder.
Background technology
In the prior art, the automobile brake retarder is to adopt magnet coil generation work magnetic field, produces lock torque, thereby makes car deceleration.This retarder, its consumption of current is big, and device is heavy, all has problems in installation, use.
Summary of the invention
The purpose of this utility model provides a kind of in light weight, retarder that consumption of current is little.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of retarder mainly is made up of stator and rotor, and wherein, stator is rack-mount, and support is fixedly mounted on the car chassis, and permanent magnet is housed on the stator, and the magnetic pole of magnet is staggered to be arranged, and rotor is fixed on the transmission shaft, and coil winding is housed in the rotor.
After adopting said structure, the utility model in use, when automobile does not need glancing impact, the gap of stator plane and rotor plane is bigger, rotor is in the weak magnetic area territory that stator produces, during the rotor running, because of there not being enough magnetic force line cutting, and can't form current vortex, thereby do not produce lock torque; When automobile needs glancing impact, the gap of stator plane and rotor plane is less, and rotor is in the strong magnetic area territory that stator produces, during the rotor running, the coil winding cutting magnetic line in rotor and the rotor, and form powerful current vortex, thereby produce powerful lock torque, make car deceleration.
The utility model adopts permanent magnet, replaces magnet coil generation work magnetic field in the prior art, and is in light weight, and permanent magnet has avoided consumed power to produce magnetic field, so consumption of current is little; Simultaneously, adopt coil winding in the rotor, increased the induction electricity eddy current of rotor, lock torque is further strengthened, thereby make the deceleration and stopping performance of retarder more powerful.
Description of drawings
Fig. 1 is structural representation of the present utility model (a not mode of operation);
Fig. 2 is a working state structure scheme drawing of the present utility model;
Fig. 3 is a stator structure scheme drawing of the present utility model;
Fig. 4 is a rotor structure scheme drawing of the present utility model.
The specific embodiment
At first, consult shown in Figure 1ly, the retarder that the utility model disclosed mainly is made up of stator 1 and rotor 2.
Wherein, stator 1 is installed on the support 3, and support 3 is fixed on the car chassis (not shown), and a group permanent-magnet 4 is housed on the stator 1, and the magnetic pole of these magnet 4 is staggered to be arranged, as shown in Figure 3.
The utility model in use, when automobile needs glancing impact, stator 1 is drawn close to rotor 2 under the effect of external force, as shown in Figure 2, the gap on stator 1 plane and rotor 2 planes is less, and rotor 2 is in the strong magnetic area territory that stator 1 is produced, in the time of rotor 2 runnings, the magnetic line of force in rotor 2 and coil winding 6 cutting strong magnetic area territories, produce powerful current vortex and magnetic force, thereby produce powerful lock torque, make car deceleration.
