Electrodynamic conical disk on-off cam self-adapting automatic gear shifting hub

Abstract

The invention discloses an electric cone plate clutch cam adaptive automatic gear shifting hub which comprises a hub frame, a box body, a motor arranged in the box body, a transmission shaft and a detent which are arranged in the box body and in running fit with the box body, also comprises a gear-down transmission shaft, a gear-down transmission mechanism arranged at the gear-down transmission shaft and a cone plate clutch cam adaptive gear shifting assembly arranged at the transmission shaft. The gear-down transmission shaft is arranged in the box body, in running fit with the box body and parallel to the transmission shaft. The adaptive automatic gear shifting hub can render the output power of the motor and the running state of the vehicle in optimum matching state so as to realize the balancing control of vehicle driving moment and comprehensive running resistance; under the condition without cutting off driving force, automatic gear shifting adaptive to the change of the running resistance is good for the high efficient energy saving of vehicles and mechanical power equipment, and compared with other automatic gearbox, the gear shifting hub has the advantages of small volume, light weight, simple and compact structure and low manufacturing cost and is suitable for being arranged at the hub and suitable for light electric bicycles with small size.

Description

technical field [0001] The invention relates to an electric wheel hub, in particular to an electric cone disc clutch cam self-adaptive automatic transmission wheel hub. Background technique [0002] In the prior art, electric vehicles, electric motorcycles, and electric bicycles basically control the speed by directly controlling the current through the speed control handle or the accelerator pedal, or use a manual mechanical automatic transmission mechanism to realize the speed change. The operation of the handle or the accelerator pedal depends entirely on the operation of the driver, which often results in a mismatch between the operation and the driving conditions, resulting in unstable operation of the motor and stalling. [0003] In an electric vehicle, the transmission device is operated and controlled by the rider only based on experience without knowing the driving resistance, which inevitably has the following problems: 1.

Problems solved by technology

The operation of the handle or accelerator pedal depends entirely on the driver's operation, often resulting in a mismatch between the operation and the driving conditions, resulting in unstable operation of the motor and stalling

[0003] In an electric vehicle, the transmission device is operated and controlled by the rider only based on experience without knowing the driving resistance, which inevitably has the following problems: 1. When starting, going uphill and with a heavy load, the motor speed is forced to increase due to the increase in driving resistance. Decline to work in the low-efficiency area, causing the motor to stall, heat up, or even stop rotating when the battery increases the supply current

2. Since there is no mechanical transmission to adjust the torque and speed, it can only be used in plain areas, and it cannot be used in mountainous, hilly and heavy-load conditions, which reduces the scope of use; 3. The installation space at the drive wheel is small, and it is very difficult to install the motor It is difficult to accommodate automatic transmission and other new technologies; 4. It does not have the function of self-adaptation, and cannot automatically detect, correct and eliminate the driver's operation errors; 5. When the vehicle speed changes suddenly, the motor will be in an unsteady state running, it will inevitably cause the motor power and driving resistance to be difficult to match

6. The continuation distance is short, the climbing ability is poor, and the adaptability range is small

[0004] In order to solve the above problems, a series of automatic transmissions have appeared, but due to the complex structure and high cost, there are problems that cannot be practically applied.

[0005] Therefore, there is a need for an automatic transmission hub, which has a simple structure, small size, and light weight, and can adapt to changes in driving resistance without cutting off the driving force. Problems with road use, little space required for installation
