Abstract
The utility model discloses an electric eddy current speed reducer which mainly consists of a rotor fraction (2) and a stator fraction (3). The stator fraction is fixed on a chassis of a vehicle through an interface support frame (1). A plurality of groups of coils (4) with opposite polarities are equipped on a fixed stator. The rotor is fixedly equipped on a middle connection flange (5) which is connected with a vehicle transmission shaft. A gap between the rotors which are symmetrical at both sides of the stator and the stator is uniform and adjustable. The electric eddy current speed reducer of the utility model has an obvious speed reducing effect and a stable performance which is applicable for various trucks and buses with a wide application range. And the electric eddy current speed reducer also makes vehicle driving stationary and comfort, increases a safety coefficient of driving crew and vehicles, increases a service life of a vehicle brake system, a brake block and a tire, and reduces a vehicle maintenance cost, which has a small volume, a light quality, a low energy consumption, a beautiful appearance, a convenient installation and maintenance and a various operation ways, and is flexible and reliable.
Description
Affiliated technical field
The utility model relates to auto parts and components, is specifically related to a kind of structure of current vortex retarder.
Background technology
At present, automobile runs into following problem through regular meeting under steam: in the galloping way, the snub meeting makes the brake block friction produce high temperature, wheel hub high temperature passes on the steel ring, very easily cause blowout, cause accident to take place, and brake block, tire chafing are very fast; Sail in mountain area or descending way two garages, needs often brake, owing to need often brake, the friction of brake block and wheel hub produces high temperature, and at present, most of vehicle is an additional water tank cooling system onboard, make the steel ring cooling, this kind type of cooling need frequently discharge water, and it is very inconvenient to operate; Three automobiles travel in rain, snow sky, and during snub, wheel can produce sideslip, causes the generation of overturn accident.
Summary of the invention
The purpose of this utility model provides a kind of current vortex retarder and solves the problems referred to above that run in the vehicle '.Vehicle has been installed this retarder can exempt to adorn the water tank cooling system, reduces the abrasion of brake block, tire, prolongs the useful life of brake block, tire, protection car load braking system.
Technical solution of the present utility model is: this retarder mainly is made up of rotor portion and stationary part, stationary part is fixed on the chassis of vehicle by interface cradle, the opposite polarity coil of many groups installs and fixes on the stator, adpting flange in the middle of rotor is fixedly installed in, middle adpting flange is connected with vehicular transmission shaft, and symmetry is consistent adjustable with the gap between the stator at the rotor on stator two sides.
When giving the coil electricity that is fixed on the stator, stator and rotor constitute the loop, produce electromagnetic eddy and act on the rotor, and the moment of resistance that is delivered on the power transmission shaft by rotor can make the speed of a motor vehicle steadily descend, because not friction, so just there is not abrasion yet.
The utlity model has following advantage: 1, slow effect is obvious, and stable performance is applicable to all kinds passenger vehicle, lorry, applied range; 2, can make vehicle ' steadily comfortable, improve the coefficient of safety of driver and crew and vehicle; 3, improve the useful life of motor vehicle braking system, brake block, tire, reduced the maintenance cost of vehicle; 4, little, the light weight of volume, power consumption is low, specious, installation and maintenance convenient, the various and flexibility and reliability of mode of operation.
Description of drawings
Fig. 1 is the utility model structural representation
Among the figure: adpting flange in the middle of 1 interface cradle, 2 rotor portions, 3 stationary parts, 4 coils, 5
Embodiment
As shown in Figure 1, this retarder mainly is made up of rotor portion 2 and stationary part 3, stationary part 3 is connected with the interface cradle 1 of hot investment casting, interface cradle 1 is fixed on the chassis of vehicle, stationary part base plate system is formed by the accurate punching out of corrosion resistant plate, four groups of opposite polarity coils 4 are fixedly mounted on the stator, the coil magnetic core adopts the good DT material of magnetic conduction to make, the rotor of whole smart casting is fixedly mounted on the middle adpting flange 5, middle adpting flange 5 is connected with vehicular transmission shaft, and rotor symmetry gap between stator two sides and stator is consistent adjustable.
When needs are slow, by button or bat-handle switch, foot switch gives coil electricity, can produce the moment of resistance that acts on the power transmission shaft.Determine the coil number of energising according to the speed of a motor vehicle, high tap position can produce and is equivalent to 80% braking effect.During low speed driving, use retarder to get final product Brake stop with braking system hardly.
Motor vehicle equipment behind the retarder, in the middle snub of running at high speed, because the effect of retarder; car speed is descended from high-speed smooth soon, reduce the wearing and tearing of brake block, tire, the braking system that protection is whole; and travel in the sleet sky, snub can not produce the sideslip phenomenon yet.
Travel in the mountain area or in descending way, because the effect of retarder, the brake number of times significantly reduces, owing to do not need frequent apply the brakes, brake block can not produce high temperature, so also just do not need the water tank cooling system that adds, brake system, brake block, tire parts significantly improve useful life.
