Abstract

The invention discloses an automatic transmission shifting fork gear-shifting mechanism, a gear-shifting executing method and an automobile. The automatic transmission shifting fork gear-shifting mechanism comprises a shifting fork assembly and an executing motor assembly, wherein the shifting fork assembly is provided with a shifting fork and a shifting fork rod; the shifting fork is fixed to theshifting fork rod; the shifting fork rod comprises a shifting fork lower end support, a shifting fork upper end support and an executing outer thread arranged at one end of the shifting fork upper end support; the executing motor assembly is provided with a motor end cover, a motor casing fixed to the motor end cover, a motor rotor placed in the motor casing, and a motor rotating shaft thread sleeve penetrating into the motor rotor from the motor end cover; an executing inner thread is arranged on the motor rotating shaft thread sleeve, and is matched and connected with an executing outer thread; and the shifting fork rod moves up and down and drives the shifting fork assembly to move to shift gears. The automatic transmission shifting fork gear-shifting mechanism is quick in response, accurate in executing force and displacement control, smooth in gear shifting, reduced in cost, and improved in using comfort.

Description

technical field [0001] The invention relates to the field of automobile automatic transmissions, in particular to an automatic transmission fork shift mechanism, a shift execution method and an automobile. Background technique [0002] The automatic transmission fork shifting mechanism of the prior art is as Figure 1 to Figure 4 As shown, it includes a shift fork assembly 1 and a hydraulic valve plate assembly 3, wherein the shift fork assembly 1 includes a shift fork lower end support 121, a shift fork upper end support 122, and a shift fork upper end support 122 that are fixedly installed on the puller.
