Intelligent self-adaptive automatic speed change system with transmission sensing function

Abstract

The invention discloses an intelligent self-adaptive automatic speed change system with a transmission sensing function. The intelligent self-adaptive automatic speed change system comprises a high-speed gear transmission mechanism, a low-speed gear transmission mechanism, a transmission bridge used for outputting power and a transmission sensing mechanism used for transmitting power between a motor power output assembly and a forward gear power input assembly. By the adoption of the technical scheme, under the condition that driving force is not cut off, gear shifting speed changing is automatically carried out along with driving resistance changes in a self-adaptive mode, the gear shifting is smooth the efficient operation interval of the motor is greatly increased, the system can be used in mountainous areas, hills and heavy-load conditions, load changes of the motor or an engine are gentle, and a pure electric vehicle is stable in operation and high in safety. Meanwhile, the rotating speed and the torque of the motor can be adaptively adjusted through the displacement detection device, so that the motor is in a high-rotating-speed and high-efficiency working state, the energy consumption is low, the stability and the reliability of the motor are improved, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to an intelligent adaptive automatic transmission system with a transmission sensing function. Background technique [0002] Due to the limitations of its transmission structure, the existing electric vehicles are completely controlled by the driver based on experience when the driving resistance cannot be accurately known during driving. The actual driving conditions do not match, causing the motor to stall. Especially when the vehicle is under low-speed and heavy-load conditions such as starting, climbing, and headwind, the motor often needs to work at low efficiency, low speed, and high torque, which is likely to cause accidental damage to the motor and increase maintenance and replacement costs. It directly affects the cruising range of the battery. For models with high economic requirements such as electric logistics vehicles, the traditional variable speed transmission...

Problems solved by technology

[0004] However, the existing cam adaptive automatic transmission devices are only suitable for rear-mounted rear-drive or front-rear-drive transmission modes, and the transmission efficiency is not ideal all the time.

Moreover, when the vehicle is under low-speed and heavy-load conditions such as starting, climbing, and headwind, the existing automatic transmission cannot detect the resistance torque in real time, resulting in the motor often needing to work at low efficiency, low speed, and high torque, which cannot be based on the actual situation. Adaptive adjustment of the speed and torque of the motor can easily cause accidental damage to the motor, increase maintenance and replacement costs, and also directly affect the cruising range of the battery
