Abstract

The invention discloses an electromagnetic control type air loss energy consumption removing and low-speed performance improving device for a hydrodynamic retarder. The device is connected between a transmission and the hydrodynamic retarder. The device comprises a planetary gear train, a magnetic powder type electromagnetic brake, a magnetic powder type electromagnetic clutch and a casing. The planetary gear train comprises a planet carrier, a sun gear, a gear ring and a plurality of planetary gears. The planetary gears are distributed between the sun gear and the gear ring evenly, meshed with the sun gear and the gear ring respectively and arranged on the planet carrier. The planet carrier is fixedly connected on a driven gear output shaft of the transmission, the sun gear is fixedly connected on a hydrodynamic retarder input shaft, the magnetic powder type electromagnetic brake is arranged between the gear ring and the casing, and the magnetic powder type electromagnetic clutch is arranged between the gear ring and the hydrodynamic retarder input shaft. The device can remove the air loss energy consumption of the hydrodynamic retarder and improve the low-speed performance of the hydrodynamic retarder and is simple in structure, convenient to use, low in cost, reliable in work and excellent in performance.

Description

technical field

[0001] The invention relates to an electromagnetically controlled device for eliminating air loss energy consumption of a hydraulic retarder and improving low-speed performance, belonging to the technical field of vehicle auxiliary braking. Background technique

[0002] At present, when the vehicle is under continuous braking for a long time, high-intensity braking or frequent braking, the temperature of the brake disc will increase significantly, resulting in a decrease in the friction factor, aggravated wear, and dangerous heat loss of partial or even complete loss of braking efficiency. recession phenomenon. Although the application of anti-lock brake system (ABS) and electronic brake force distribution system (EBD) has improved the stability and reliability of vehicle braking, they have little effect on the thermal fading phenomenon of brakes. At present, many countries including my country have clearly stipulated that passenger cars and trucks above a c...
