Example 1
As shown in fig. 5-7, a reverse brake separating device of a centrally-mounted electric bicycle adopts a structure that a clutch block stop block 11 is separated from a screw rod 1. The shaft is of a left-right shaft structure and is formed by combining a left shaft 3 and a right shaft 4. A part of the right shaft 4 is in sliding fit with the inner ring of the screw rod 1, the end part is a crank connecting end 7, the other part is inserted into the left shaft 3, and the end part of the inserted part is fixedly connected with the inside of the left shaft 3. One end of the left shaft 3 is provided with a left crank, the other part of the left shaft is sleeved on the right shaft 4, and the end part of the left shaft is fixedly connected with the inner ring of the screw rod 1; the output of the motor rotor 9 is directly or through a reduction mechanism connected with a motor connecting part 12, and the motor connecting part 12 is connected with the motor output part 5 through a unidirectional ratchet wheel 8.
Part of the outer ring of the screw rod 1 is connected with the motor output part 5 through one or more bearings, at least one of which is a thrust bearing for bearing the axial force between the motor output part 5 and the screw rod 1. The ratchet structure can also adopt any one-way clutch structure.
The reverse brake separating device can adopt a torsion sensor or a speed sensor. The torsion sensor is arranged on the surface of the left shaft 3, and the torsion sensor collects a center shaft torsion signal to the motor controller. The speed sensor is used for detecting the rotation speed of the middle shaft, the implementation mode is not limited, for example, the rotation speed of the left shaft 3 or the right shaft 4 can be detected by arranging magnetic steel on the middle shaft and arranging a Hall sensor at a corresponding position.
During riding, the crank is trampled forward, the middle shaft transmits torsion to the fixedly connected screw rod 1 with the crank by means of key connection, the screw rod 1 rotates, the rear wheel has running resistance and can act on the clutch block 2 reversely by the fluted disc, so that the clutch block 2 is driven to move inwards and contact with the motor output part 5, then the crank tramples the torsion to drive the clutch block 2 to rotate by the screw rod 1 and transmit the movement to the fixedly connected sprocket with the clutch block by means of the clutch action, the rear wheel of the belt wheel bicycle starts to rotate, and at the moment, the clutch block realizes torsion transmission by means of the pressure of the screw rod and the compression friction of the motor output part 5 due to the combined action of the torsion of the screw rod and the resistance of the rear wheel to the clutch block by means of a chain. In the above process, when the pedal of the right shaft is stepped on, the right shaft 4 drives the left shaft 3, the left shaft 3 drives the screw rod 1 to rotate, and the screw rod 1 is directly transmitted to the screw rod 1 through the right shaft 4 after the right shaft 4 runs through the idle stroke after the right shaft 4 runs stably, because the spline of the right shaft 4 and the key groove of the screw rod 1 have a section of idle stroke for enabling the middle shaft to generate torsion, the right shaft 4 drives the left shaft 3 to rotate, the left shaft 3 and the screw rod 1 have a torsion, and the torsion sensor arranged on the surface of the right shaft drives the motor. When the left shaft pedal is stepped, the left shaft 3 directly generates torsion with the screw rod 1, a torsion sensor arranged on the surface of the left shaft 3 sends out a signal to a motor, meanwhile, the left shaft 3 drives the right shaft 4 to rotate, and after the idle stroke is finished, the stepping force of the left shaft 3 is transmitted to the screw rod 1 through the right shaft 4; the motor can drive the motor output part to rotate due to the single rotation characteristic of the ratchet wheel. Therefore, the manual power and the electric power act on the clutch block 2 together to drive the electric vehicle to travel, and the manual power and the electric power drive the electric vehicle to travel together.
At this time, if the battery is not powered on or the motor is turned off, since the motor output part 5 is connected to the motor connecting part 12 by means of the ratchet mechanism, the motor at this time constitutes resistance, and the ratchet mechanism is moved forward, so that the motor output part 5 is separated from the motor connecting part 12, and the riding state is the same as that of a normal bicycle at this time, and is driven by pure manpower, and the resistance of the motor in the running process is avoided.
When the pedal is stopped, the motor connecting part 12 can be driven to rotate due to the rotation inertia of the motor, the motor output part 5 can be driven to rotate continuously due to the single action of the ratchet wheel or the single clutch, and the middle shaft can form reverse resistance due to the pedal stopping, so that the screw rod 1 reversely rotates, the clutch block 2 is separated from the motor output part 5, and personnel injury caused by the inertia of the motor is avoided.
When the reverse brake is needed, the crank is trampled backwards, the middle shaft transmits trampling force to the screw rod 1 fixedly connected with the crank, the screw rod 1 reversely rotates, the clutch block 2 is driven to be separated from the motor output part 5, and the chain wheel is driven to reversely rotate, so that the reverse brake is realized. At the moment, whether the motor is running or not can be guaranteed, the driving force of the motor can not act on the chain wheel and the crank, personnel injury or damage to a vehicle caused by movement of the motor is avoided, and meanwhile, the chain wheel moves reversely to drive the brake to lock, so that vehicle braking is realized. Through the cooperation of key connection and clutch block dog rotation, the stroke of stopping that falls of effective control clutch block guarantees the stability and the security of electric bicycle performance.
The foregoing examples merely illustrate embodiments of the invention and are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
