HSQ Series of Electromagnetic Retarder
Application:
HSQ series of automobile electromagnetic retarders are the environment-protective hi-tech products, designed upon the principle of electromagnetic mechanics, which are used as a necessary supplement for the brake system, offering auxiliary braking force to the brake system. As a result of this, the easement and security of vehicle running have been promoted greatly and for the brake disks, tires and braking system, wear and tear have been reduced so as to prolong their service lives. Furthermore, the maintenance fee can be saved a lot. In the meantime the noise and powder causing pollution have been reduced a great deal owing to the use of the retarder. The ratarder is specially applied to medium and heavy cargo trucks,and top-graded passenger cars.
Briefs of the structure
HSQ series of speed reducer mainly contains following parts:
1) interface bracket
2) rotor
3) stator
4) coil
5) mid joint flange
The interface bracket (part1) is to be cast precisely and mounted on the chassis or car body. The rotor (part2) which are pided into two parts (front and back) are to be cast with light and fine ferrous magnetic materials containing good magnetic conductivity and it is specially made into a form of blade wheel in order to dispel the heat caused by braking. The two rotors are mounted on two sides of the stator in symmetry through the mid joint flange (part 5), keeping with an appropriate gap (adjusted by spacer). The stator (part 3) is a stamping workpiece made of light and high strength material that is magnetic-proof. Around the outside circle of the stator are mounted four sets of magnetic coils with unlike poles, which are wounded on 8 magnetic cores with high magnetic conductivity. The coils (part 4) are to be winded with wires containing characters of high heat resistance and high electric conductivity and be pided into four groups (each group has two) with unlike poles. The mid joint flange (part 5), which is made of fine material by precise machine, is to be connected with the driving shaft of the automobile.
Operation and maintenance
1.HSQ series retarder have five shifts:
0 shift | NO effect in reducing the speed |
1 shift | The speed will be reduced by 25% |
2 shift | The speed will be reduced by 50% |
3 shift | The speed will be reduced by 75% |
4 shift | The speed is to be reduced to 100% |
The lighted lamp on the instrument the speed panel indicates that the retarder is working in service, when there is no need for the service of retarder, the gear may reverse to 0 position, then the lamp is not light at this moment.
2. It is recommended that the retarder and the brake system be used comprehensively so as to prolong the service life of tires and brake system.
3. The retarder is to be checked and cleaned once after it has covered 5000km(cooled first). The dust on the Surface of rotator can be removed with high pressure cleaner, the stator(especially for the stator wiring post)may be washed with low pressure cleaner.

Main advantages
1.Safe and comfortable: It can bear 30%-80%braking when bus is speeding down.Protect bus against running aside due to uneven wear or improper adjustment of the brake. Avoid ineffective braking due to overheating of brake. Project the tires against bursting caused by overheating of brake hub.
2. Economical and protection: Prolong the service life of brake system and save the maintenance time. Reduce the cost.
3. Green environment protection: Reduce the eliminate the noise and dusts caused by brake friction.
4. Easy operation: Independent auto control and hand operation satisfy the driver’s habit.
5. The tires’s service life to be prolong 30%~50% in average
6. The maintenance fee for brake system and tires reduced by 5-8times
7. Even driving on express way, the service life of brake disk can be prolonged by 4-10 times in average.
