Noise reduction centrifugal clutch structure

Abstract

The noise reduction centrifugal clutch structure comprises a driving disc and a transmission wheel, the driving disc is connected with a motor rotating shaft and driven by the motor rotating shaft, the transmission wheel is connected with a hub body, the driving disc is sleeved with a clutch disc, and the connection or separation state between the driving disc and the transmission wheel is adjusted through the clutch disc; a clutch claw is arranged on the clutch disc, a reset device enabling the clutch claw to have the trend of being closed inwards all the time is arranged between the clutch claw and the clutch disc, the clutch claw comprises a balance weight part and a shaft part, the shaft part serves as the center of the swing direction of the clutch claw, a friction part is arranged on the circumferential side wall of the shaft part, and when the clutch claw swings to the maximum amplitude around the shaft part, the friction part is driven to rotate. The friction part is tangent to the transmission wheel, tangential acting force forces the surface of the friction part to be in friction connection with the inner surface of the transmission wheel tightly, friction transmission is achieved between the friction part on the clutch claw and the transmission wheel, a ratchet wheel used for buckling is not arranged any more, noise is lower, collision between structures is reduced, the service life is prolonged, and the transmission speed is higher and more stable.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a transmission element, in particular to a noise reduction centrifugal clutch structure. Background technique [0002] In people's daily life, electric vehicles are an important means of transportation. Electric vehicles have the advantages of flexibility and convenience, and are very convenient and labor-saving to use. They are the preferred tool for short-distance travel. In order to limit the driving speed of electric vehicles, the government promulgated the new national standard electric vehicle regulations. The specific content is as follows: 1. The maximum speed of the vehicle does not exceed 25km / h; 2. The weight of the vehicle does not exceed 55kg including batteries; 3. . The power of the motor is not greater than 400 watts; 4. The voltage of the battery is not more than 48 volts; 5. The pedal function is required. The heavier the object, the faster the speed and the gre...

Problems solved by technology

[0008] The above-mentioned electric wheel hub power output device, electric wheel hub motor and centrifugal clutch structure can better solve the technical problems such as insufficient power when the electric vehicle goes uphill, and when the motor is not working, it still cannot push the electric vehicle backward. Some deficiencies, for example, during the shifting process of the electric vehicle, when the pawl of the centrifugal clutch structure is engaged with the ratchet wheel, the collision interference between the two will produce a large noise, and it is easy to cause damage to the structure itself
