Problems solved by technology

Due to the thickness of the large flat turntable itself (different types of eddy current retarders are generally about 15-25 mm), it takes time to conduct conduction from the large flat turntable to the blades, and its heat dissipation speed is slower than the heat generation speed, and the heat dissipation effect is poor, resulting in The temperature of the rotor rises, the higher the temperature, the greater the deformation and recession of the thermoplastic, and the greater the expansion of the rotor, resulting in a larger air gap between the rotor and the stator, which seriously affects the performance of the retarder

Embodiment Construction

[0014] Such as Figure 1-3 The rotor of an eddy current retarder shown includes a large-plane turntable 1 , a connecting flange 2 , a protective cover 3 , and a cooling vane group 4 .

[0015] The radiating blade set 4 is arranged on the back of the turntable 1 , and the protective cover 3 covers the outside of the radiating blade set 4 . The axial central part of the turntable 1 and the flange 2 is an axial through hole, and the flange 2 is used for installing and connecting the rotor on the rotating shaft.

[0016] A plurality of radial through holes 5 are drilled in the inside of the turntable 1 along the radial direction. Such as image 3 As shown, a plurality of radial through-holes 5 are evenly distributed in the circumferential plane of the turntable, and the center line of the radial through-holes 5 deviates from the radial straight line of the rotor by a certain angle, and the direction of the angle deviation is opposite to the direction of rotation of the rotor, an...

Abstract

The invention discloses a rotor of an eddy current retarder. The rotor comprises a turntable, wherein an axial through hole is formed in the axial center part of the turntable; multiple radial through holes are formed in the turntable, and are communicated with the axial through hole; and the multiple radial through holes are uniformly distributed in the peripheral plane of the turntable. The center line of the radial through holes is deviated from the radius straight line of the rotor by a set angle. As the radial through holes are added in the turntable, when the turntable rotates, the heat generated on the turntable is directly dissipated through airflows; and the turntable has cooling holes, so that the cooling performance of the rotor is greatly improved, and the performance of the retarder is enhanced.

Description

technical field [0001] The invention relates to a vehicle deceleration component, in particular to a rotor of an eddy current retarder. Background technique [0002] In the development of modern automobiles, the requirements for driving safety, economy, environmental protection and riding comfort of automobiles are getting higher and higher. More and more luxury buses, urban buses and heavy trucks are equipped with eddy current retarders as Auxiliary braking system, which is installed in the transmission system of the vehicle, generates resistance against the direction of rotation between the rotor and the stator that rotates with the transmission shaft through the principle of eddy current, so as to play the function of slowing down the vehicle, thereby improving the performance of the vehicle. brake safety. It can be installed at the rear end of the transmission, between drive shafts or other locations. Because there is a certain air gap (0.75-1.5mm) between the rotor an...
