Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0047] Such as figure 1 As shown, the present invention provides a disc-type permanent magnet eddy current flexible retarder for vehicles, which includes a first rotor 110 and a second rotor 120 arranged in the axial direction. The first rotor 110 and the second rotor 120 are respectively fixed on two sides of the connection plate 130, one side is connected with the transmission shaft of the vehicle, and the other side is connected with the output shaft of the gearbox. While driving the transmission shaft of the vehicle to rotate through the output shaft of the gearbox, it rotates synchronously together with the first rotor 110 , the second rotor 120 and the connecting disc 130 .

[0048] A certain gap is left between the first rotor 110 and the second rotor 120, and the fir...

Abstract

The invention discloses a vehicular disk-type permanent magnet eddy current retarder, comprising a first rotor, a second rotor, a first stator, a second stator, a support frame, a connecting rod and an execution mechanism, wherein the first rotor and the second rotor are coaxially arranged at interval; the first stator and the second stator are coaxially arranged between the first rotor and the second rotor; the support frame is fixedly connected with a vehicle gearbox shell or a frame; the middle part of the connecting rod is connected with the extension end of the support frame by adopting a cylindrical pair, and two ends of the connecting rod respectively form spherical hinges with the peripheral edges of the first stator and the second stator; and the execution mechanism is articulated with the other extension end of the connecting rod. A high-performance neodymium iron boron permanent magnet provides a magnetic field, so that power supply is not needed, and the defect of power consumption of an electric eddy current retarder is overcome; two disks are articulated together by the connecting rod via a joint bearing to avoid axial force caused by non-uniform air gaps on two sides, and simultaneously, the maximum axial resistance is skillfully converted into circumferential rotation and axial motion to reduce the driving force.

Description

technical field [0001] The invention belongs to the technical field of automobile retarders, in particular to a disc-type permanent magnet eddy current retarder for automobiles. Background technique [0002] With the improvement of road quality and the improvement of automobile manufacturing technology, in order to alleviate the pressure of large transportation volume and high transportation cost, automobile transportation is developing towards the trend of large load and high speed. Overloading and overspeeding occur from time to time. The proportion of traffic accidents caused by speeding is on the rise. At present, the driving brake device of the car is a friction brake. The braking force is generated through the friction between the brake shoe or brake caliper and the brake drum or brake disc. The reduced kinetic energy or potential energy of the car is converted into heat, and finally Dissipated into the air by heat transfer and convection. When the car is running, th...
