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...

Embodiment Construction

[0034] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0035] Such as figure 1 and figure 2 As shown, an intelligent self-adaptive automatic transmission system with a transmission sensing function mainly includes a high-speed gear transmission mechanism, a low-speed gear transmission mechanism, a transmission bridge 1 for outputting power, and a motor power output assembly and a forward gear The transmission and sensing mechanism that transmits power between power input components.

[0036] See Figure 1-Figure 3 The transmission bridge 1 includes a main shaft 1a and a first transmission shaft 1c and a second transmission shaft 1d coaxially arranged at both ends of the main shaft 1a. A forward gear transmission sleeve 1b is rotatably fitted on the main shaft 1a. The main shaft The end of 1a close to the first transmission shaft 1c drives the first transmission shaft 1c to rotate synchronously through the int...
