The invention provides a parking mechanism for an automatic gearbox and a gearbox. The parking mechanism comprises a parking cam, wherein a parking spring is arranged on the parking cam in a sleeving manner and is positioned on the inner side of a guide plate; a return spring is arranged on the outer side of the parking spring in a sleeving manner; one end of the return spring is pressed against one end surface of the guide plate; the other end of the return spring is pressed against a pin; a passive pawl is arranged at one end of a parking push rod; a rod part is arranged at the other end of the parking push rod; a circular through hole is formed in the part, accommodated in a rod-shaped body of the parking cam, of the rod part, and corresponds to a strip-shaped through hole; the parking push rod is connected with the parking cam through the pin; the passive pawl is provided with a plurality of first pawl bulges; each first pawl bulge comprises a first inclined surface, and each first pawl bulge is depressed inwards to form a first groove adjacent to each first inclined surface; a first pawl groove is formed between two adjacent first pawl bulges; the position between a second inclined surface and a third inclined surface is depressed inwards to form a second groove. The problems that the parking mechanism is poor in compactness, and has a demanding requirement on the strength of a shell are solved.
Description
technical field [0001] The invention relates to the technical field of automatic transmissions, in particular to a parking mechanism of the automatic transmission and the automatic transmission. Background technique [0002] Cars can be divided into manual transmission cars and automatic transmission cars according to the different shifting methods. Among them, the automatic transmission car has an automatic transmission. Automobiles with automatic transmissions are favored by people because they are easy and convenient to drive. Automatic transmission has become the mainstream direction of transmission development and is more and more popular. The parking mechanism is a safety device in the automatic transmission. Its function is to prevent the car from sliding, so that the car can be parked at a certain position or even on a slope reliably and without time limit. [0003] At present, the structure of the parking mechanism in the automatic transmission is also not the sa...
