Embodiment 1

[0044] Such as Figure 1 to Figure 5 As shown, a parking system driven by a shift drum shift groove includes a shift drum 1, and the shift drum 1 includes a shift groove 2, the shift drum 1 is a cylinder, and the shift drum The groove 2 is an annular groove arranged around the circumferential surface of the shift drum 1. The shift groove 2 includes a four / reverse gear groove, and the four / reverse gear groove includes a flat area 201 and is connected to the flat area. The fourth gear area 202 and the reverse gear (R gear) area 203, the fourth gear area 202 and the reverse gear area 203 are respectively arranged in relative offsets along the axial direction of the shift drum 1, and the fourth gear area 202 and the Between the flat areas 201, between the reverse gear area 203 and the flat area 201, oblique area transitions are respectively provided. The shift slot 2 is provided with a shift slider 3 and a parking slider 4. The shift slider 3 is connected to the shift actuator, a...

Embodiment 2

[0059] Such as Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the shifting groove includes the second / sixth gear groove, and the second / sixth gear groove includes a flat area 201, and a second gear area 204 connected to the flat groove, The sixth gear area 205, the second gear area 204 and the sixth gear area 205 are arranged with relative offsets along the axial direction of the shift drum 1, between the second gear area 204 and the flat area 201, the sixth gear area There is an oblique zone transition between the zone 205 and the flat zone 201; the second / sixth gear slot is provided with a shift slider 3 and a parking slider 4, while there is no parking slider in the fourth / reverse gear slot 4. The shift slider 3 in the second / sixth gear slot and the shift slider 3 in the fourth / reverse gear slot are at the same circumferential position of the shift drum 1 and move synchronously.

[0060] In this embodiment, the shift drum rotates in rev...

Embodiment 3

[0063] Such as Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the shift gate includes a third / fifth gear slot, and the third / fifth gear slot includes a flat area 201, and a third gear area connected to the flat slot, The fifth gear area, the third gear area 206 and the fifth gear area 207 are respectively arranged with relative offsets along the axial direction of the shift drum 1, between the third gear area 206 and the flat area 201, the fifth gear area 207 and the flat area 201 are respectively provided with an oblique area transition; the third / fifth gear slot is provided with a shift slider 3 and a parking slider 4, while there is no parking slider 4 in the fourth / reverse gear slot ; The shift slider 3 in the third / fifth gear slot and the shift slider 3 in the fourth / reverse gear slot are at the same circumferential position of the shift drum 1 and move synchronously.

[0064] In this embodiment, the shift drum rotates in reverse, and...

Abstract

The invention discloses a parking system with gear shifting grooves of a gear shifting drum for driving. The system comprises the gear shifting drum, the plurality of gear shifting grooves are formedin the gear shifting drum, and each gear shifting groove comprises a flat area and at least one gear area connected with the flat area; a gear shifting sliding block is arranged at the position, in the same circumferential direction as the gear shifting drum, in each gear shifting groove, all the gear shifting sliding blocks move synchronously, and a parking sliding block is arranged in any gear shifting groove. The gear shifting sliding blocks are connected with a gear shifting executing mechanism, and the parking sliding block is connected with a parking executing mechanism. In all the gearareas, only one gear area is used for driving the gear shifting sliding blocks to achieve the gear shifting function and also used for driving the parking sliding block to achieve the parking function. By means of the positions and the structural shapes of the existing gear shifting grooves of the gear shifting drum, the gear shifting function and the parking function are achieved through the samegear shifting groove in the gear shifting drum, it is avoided that a set of parking driving system is independently designed, and the space occupied by the gear shifting drum in a gearbox is saved.

Description

technical field [0001] The present invention relates to the technical field of automobile gearboxes, in particular to a parking system and method driven by a shift drum shift groove. Background technique [0002] The gearbox, also known as the transmission, is one of the main components of the car transmission system. The gearbox is a mechanism used to change the speed and torque from the engine in the car. It can change the transmission ratio of the output shaft and the input shaft in fixed or stepwise steps. The gearbox is composed of a variable speed transmission mechanism and an operating mechanism. Some cars also have a power output mechanism; most of the transmission mechanisms use ordinary gears for transmission, and some use planetary gears for transmission. [0003] The shift drum is an important part of the gearbox. Its function is to drive the shift fork to perform shift operations. The key part of the shift drum is the groove on the shift drum. One end of the shi...
