Excitation electronic retarder

Abstract

The excitation electronic retarder is characterized by comprising a cover plate, a first electromagnetic iron core, a second electromagnetic iron core, an iron core fixing plate, a central shaft, a chain wheel, a permanent magnet iron core, a sliding electrode, a connecting seat, a primary coil and a secondary coil. When the vehicle needs to decelerate, the retarder works before the brake, and the vehicle can slowly reduce the speed through dragging of the retarder, so that the loss of the brake is reduced, and the probability of sideslip during braking is also reduced. The retarder and the brake are used at the same time, the speed of the vehicle can be rapidly reduced, the braking distance is shortened, and the vehicle can stop in a short time. And when the vehicle needs to be backed up or turned around, the retarder is used as a motor, so that the vehicle can be backed up or turned around on a narrow road section or a ramp. When the primary coil and the secondary coil on the electromagnetic iron core supply power to the primary coil through the battery, the secondary coil serves as a power generation coil, consumption of the vehicle battery is reduced, the burden of a vehicle generator is relieved, and oil consumption of the vehicle is reduced.

Description

technical field [0001] The invention relates to a vehicle auxiliary braking device, in particular to an excitation electronic retarder. Background technique [0002] Existing vehicle retarders are all designed to be used on large vehicles, but can not be used on small and two-wheeled and three-wheeled vehicles because of the single installation method and excessive volume. [0003] Two-wheeled or three-wheeled vehicles often adopt the method of braking the front and rear wheels separately. When the front wheels are braked alone, the rear wheels can only rely on the traction resistance of the engine to assist deceleration. When the vehicle speed is high, The rotational speed of the engine also increases accordingly, and at this moment, the traction resistance produced by the engine is almost non-existent, which increases the probability of sideslip when the vehicle brakes. [0004] The two-wheeled vehicle does not have a reverse gear on the transmission, and it can only be a...

AI Technical Summary

Problems solved by technology

[0004] The two-wheeled vehicle does not have a reverse gear on the transmission, and it can only be assisted by human power to reverse or turn around. When encountering a narrow road section or a slope, it will be impossible to reverse or turn around because the vehicle is too heavy. When a fault occurs and you cannot drive, you cannot go to the maintenance point for maintenance by yourself.

[0005] The power required by the vehicle retarder during work can only be provided by the battery, which increases the consumption of the vehicle battery, increases the burden on the vehicle generator, and increases the fuel consumption of the vehicle accordingly
