Side-hanging taper disc type self-adaption two-gear automatic speed changing hub

Abstract

The invention discloses a self-adaptive two-speed automatic speed-change wheel hub of side hung cone disc type, comprising a left wheel hub frame, a right wheel hub frame, a housing, a power device, a transmission shaft, a wheel, a brake device arranged on the transmission shaft, a driving shaft driven by the momentum equipment, a gear speed-change mechanism arranged on the speed-change gear axis and a cone disc type self adaptive two-speed automatic speed-change assembly. The driving shaft and the speed-change gear axis are arranged in the housing and are in parallel to the transmission shaft. The self-adaptive two-speed automatic speed-change wheel hub of side hung cone disc type has the advantages that the output power of the motor and the driving status of the vehicles are always in an optimum matching status to achieve the balanced control of the driving moment of the vehicles and the synthesized driving resistance; the speed change can be operated automatically along with the change of the driving resistance by the self adaptive without cutting off the driving force, so that the invention is conducive to the energy-efficiency of the vehicles and the mechanical power equipment, and can satisfy the usage under the conditions of mountain areas, hills and heavy loads; and the transmission of the invention has a light weight and a compact structure.

Description

technical field [0001] The invention relates to a wheel hub of a motor vehicle or mechanical power equipment, in particular to a side-mounted conical disc type self-adaptive two-speed automatic transmission wheel hub. Background technique [0002] In the prior art, motor vehicles such as automobiles, motorcycles, and electric bicycles basically directly control the current control speed through a speed control handle or an accelerator pedal, or use a manual mechanical automatic speed change mechanism to realize 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 power unit. [0003] Motor vehicles need to achieve intelligent control of current, and load, torque or speed are important parameters. The measurement of this index generally uses a variety of sensors to obtain relevant parameters ...

Problems solved by technology

However, this device does not have an automatic shift function

[0004]Taking an electric vehicle as an example, the transmission device controlled by the rider only based on experience without knowing the driving resistance inevitably has the following problems: 1. When starting, going uphill and under heavy load, due to the increase of driving resistance, the motor speed is forced 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.

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

[0005] Therefore, it is necessary to modify the transmission, which can adapt to the change of driving resistance and automatically shift gears without cutting off the driving force, so as to solve the problem that the small torque-speed change cannot meet the road use under complex conditions, and the space required for installation is relatively small.
