Title:
INTELLIGENT SELF-ADAPTIVE AUTOMATIC TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2021/110154
Kind Code:
A1
Abstract:
An intelligent self-adaptive automatic transmission, comprising a power input mechanism, a forward gear transmission system, a reverse gear transmission system, a main shaft (1) used for outputting power, and a transmission sensing mechanism used for measuring resistance torque borne by the main shaft (1); wherein the power input mechanism simultaneously drives the reverse gear transmission system and the transmission sensing mechanism, and the transmission sensing mechanism drives the forward gear transmission system. The transmission sensing mechanism comprises a forward gear primary driven gear shaft (19) driven by the power input mechanism, a forward gear secondary driving gear (20) used for transferring power to the forward gear transmission system, a transmission sensing cam sleeve (21) capable of being axially slidably sleeved on the forward gear primary driven gear shaft (19), and a displacement measurement device (25) used for measuring the displacement of the transmission sensing cam sleeve (21), wherein the transmission sensing cam sleeve (21) can synchronously rotate under the driving of the forward gear primary driven gear shaft (19); the forward gear secondary driving gear (20) is rotatably sleeved on the forward gear primary driven gear shaft (19) and transmittingly works in conjunction to a corresponding end surface of the transmission sensing cam sleeve (21) by means of an end surface cam pair, so that the transmission sensing cam sleeve (21) can be driven to be far away from the forward gear secondary driving gear (20); an elastic reset element (24) is provided between the transmission sensing cam sleeve (21) and the forward gear primary driven gear shaft (19), so that the transmission sensing cam sleeve (21) can be driven to be close to the forward gear secondary driving gear (20). The device can adaptively adjust the rotating speed and the torque of a motor, so that the motor is in a working state with high rotating speed and high efficiency, the energy consumption is low, and the stability, reliability and service life of the motor are improved; moreover, a special reverse gear transmission system is additionally provided, so that the energy of the motor is recovered, a larger speed ratio can be provided during vehicle reversing, the output torque is larger, and the device is facilitated overcoming more extreme conditions and improving the vehicle reversing safety.
