Example Embodiment

[0040] The present invention will be further described below in conjunction with embodiments and drawings.

[0041] Such as Figure 1-Figure 5 As shown, an intelligent ultra-large load adaptive automatic transmission system with reverse gear mainly includes a motor assembly, a forward gear input assembly, a forward gear transmission system, a reverse gear input assembly, a transmission axle 1 for outputting power, and A transmission sensing mechanism that transmits power between the forward gear power input assembly and the forward gear transmission system. See figure 1 with figure 2 The motor assembly includes a motor 17 and a power shaft 18 capable of rotating and synchronously rotating under the drive of the motor shaft of the motor 17. The power shaft 18 has forward gear output teeth 18a and reverse gear output teeth 18b.

[0042] See figure 1 , The forward gear input assembly includes a power input gear 23 meshing with the forward gear output teeth 18a and a power input shaft...

Abstract

The invention discloses an intelligent super-large-load self-adaptive automatic speed change system with a reversing function. The intelligent super-large-load self-adaptive automatic speed change system comprises a motor assembly, a forward gear input assembly, a forward gear speed change system, a reverse gear input assembly, a transmission axle used for outputting power and a transmission sensing mechanism used for transmitting power between the forward gear power input assembly and the forward gear speed change system. By adopting the technical scheme, the rotating speed and the torque ofthe motor can be adaptively adjusted, 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 areimproved, and the service life of the motor is prolonged; moreover, a front-engine front-drive transmission mode can be realized, and the transmission efficiency is high; and meanwhile, due to the fact that a special reverse gear speed change system is additionally arranged, the motor does not need forward and reverse rotation switching, a larger speed ratio can be provided in the reversing process, the output torque is larger, more extreme conditions can be overcome, meanwhile, the reverse gear speed is low, and the reversing safety is improved.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to an intelligent super-large-load self-adaptive automatic transmission system with a reverse gear. 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 transmi...
