Abstract

The invention discloses an energy-saving coasting self-adaptive automatic transmission wheel hub comprising a wheel hub carrier I, the wheel hub carrier II, a box body, a power input device, a transmission shaft, wheels and a brake device, the energy-saving coasting self-adaptive automatic transmission wheel hub further comprises a slow gear transmission shaft, a slow gear transmission mechanism which is arranged on the slow gear transmission shaft, a conical disc clutch cam self-adaptive transmission assembly which is arranged on the transmission shaft and an energy-saving coasting clutch device, the slow gear transmission shaft is arranged in the box body to be matched with the box body by rotation, energy-saving coasting self-adaptive automatic transmission wheel hub can fully utilize the power which is generated during the driving process of the wheels when in coasting of a vehicle, the coasting distance is long under the situation of the same power, thereby saving energy, allowing the output power and the driving status of the vehicle to be always in the best match state and realizing the balance control of the driving torque of the vehicle and the comprehensive driving resistance; the gear shift transmission can be self-adaptively automatically carried out along with the change of the driving resistance under the situation of not cutting off the driving force, thereby being conductive to the high efficient energy conservation; and the invention has the advantages of light weight, simple and compact structure and low manufacture cost, and is applicable to the characteristics of small size and portability of an electric bike.

Description

technical field [0001] The invention relates to an electric or fuel oil wheel hub, in particular to an energy-saving sliding self-adaptive automatic transmission wheel hub. Background technique [0002] In the prior art, electric vehicles, electric motorcycles, electric bicycles and fuel wheel hubs are basically controlled by the speed control handle or the accelerator pedal to directly control the current control speed or control the oil quantity to control the speed, or use a manual mechanical automatic transmission mechanism. Achieve variable speed. 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 a stall phenomenon; motor vehicles in the prior art need to slide and then stop during driving. Because during the sliding process, the wheels need to drive a series of transmission mechanisms t...

Problems solved by technology

[0003] For electric vehicles and fuel vehicles, when the rider does not know the driving resistance and only operates the transmission device based on experience, it is inevitable that there will be the following problems: 1. When starting, going uphill and with a heavy load, due to the increase in driving resistance, Force the motor speed to drop 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; or the engine stalls and the fuel consumption is too large

2. Since there is no mechanical transmission to adjust the torque and speed, it can only be used in plain areas, and cannot be used in mountainous, hilly and heavy-load conditions, which reduces the scope of use; 3. The installation space of electric vehicles at the drive wheels is small, and the installation of It is difficult to accommodate automatic transmission and other new technologies behind the motor; 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 speed changes suddenly, the motor / engine will be in an abnormal state Running under steady-state conditions will inevitably make it difficult to match the output power of the motor / engine with the driving resistance; 6. The continuation distance is short, the climbing ability is poor, and the adaptability range is small

[0005] Therefore, there is a need for an automatic variable speed wheel hub, which can make full use of the kinetic energy generated during the running of the wheel when the vehicle is sliding, the sliding distance is long under the same kinetic energy, energy is saved, and it can adapt to the change of driving resistance without cutting off the driving force. Carry out gear shifting to solve the problem that the small change of motor torque and speed cannot meet the road use under complex conditions, and the structure is simple, small in size, light in weight, and the space required for mechanism installation is small
