Abstract

The invention discloses a transmission gear shifting and parking structure and a new energy automobile. The transmission gear shifting and parking structure comprises a rotary driving mechanism, a gear shifting rotary arm, a shifting fork, a gear shifting executing mechanism, a driving guide shaft, a parking rotary arm, a parking push rod assembly and a parking executing mechanism; the rotary driving mechanism is used for driving the driving guide shaft to rotate; one end of the gear shifting rotary arm and one end of the parking rotary arm are fixed to the driving guide shaft and rotate along with the driving guide shaft; a cylindrical pin is arranged at the other end of the gear shifting rotary arm, the cylindrical pin moves along a shifting fork molded line groove formed in the shifting fork along with rotation of the gear shifting rotary arm and drives the shifting fork to move, and a plurality of positions corresponding to gears are arranged on the shifting fork molded line groove; and the other end of the parking rotary arm is hinged to the parking push rod assembly, and the parking push rod assembly drives the parking executing mechanism to achieve a parking action. According to the scheme, two actions of parking and gear shifting are achieved through one set of structure, the arrangement space of gear shifting and parking mechanisms is saved, the number of driving sources and parts is reduced, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle transmissions, and in particular relates to a gear shifting and parking structure of a transmission and a new energy vehicle. Background technique [0002] In a common automobile transmission, the parking actuator and the shift actuator are independent of each other, and each requires a set of drive systems to realize the functions, requiring many parts, taking up a large space, and costing a lot. In the field of new energy vehicles where the integration of power systems is getting higher and higher, the integration of various systems is getting higher and higher, and the traditional layout can no longer meet the space layout requirements. Contents of the invention [0003] In view of the above problems, the present invention discloses a transmission shift parking structure and a new energy vehicle, so as to overcome the above problems or at least partly solve the above problems. [0004] In or...
