Embodiment Construction

[0032] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0034] This embodiment relates to a vehicle parking device, which consists of figure 1 As shown, it includes a parking gear 1 and a parking pawl 2, wherein the parking gear 1 is fixedly set on the transmission shaft 4 of the transmission, and rotates with the transmission shaft 4, and the circumference of the parking gear 1 is evenly distributed. There are two parking teeth 101, and between two adjacent parking teeth 101, an accommodating space for the parking pawl 2 described below is embedded and engaged is formed. The parking pawl 2 is connected in the transmission housing not shown in the figure through the rotation of the first rotating shaft 201, and the end opposite to the first ...

Abstract

The invention provides a vehicle parking device which comprises a parking gear, a parking pawl and a driving rod assembly in contact matching with the parking pawl. The vehicle parking device further comprises an inhaul cable, a traction driving mechanism and a return device. The inhaul cable is connected with the driving rod assembly. The traction driving mechanism is in driving connection with the inhaul cable and is used for exerting traction force on the inhaul cable to make the driving rod assembly located at an initial position to achieve the parking movement of pushing the parking pawl to be meshed with the parking gear. The return device is connected to the driving rod assembly and conducts elastic energy storage by means of the parking movement of the driving rod assembly, and when the traction driving mechanism releases the traction force on the inhaul cable, the return device releases the elastic stored energy to drive the driving rod assembly to return to the initial position. According to the vehicle parking device, due to the fact that the inhaul cable, the traction driving mechanism and the return device are adopted for driving the driving rod assembly, the overall structure is simplified, the layout of the whole device is facilitated, the parking effect can be ensured, and the vehicle parking device is simple in overall structure and good in reliability.

Description

technical field [0001] The present invention relates to the technical field of locking the running parts of a vehicle, in particular to a vehicle parking device; at the same time, the present invention also relates to a method for controlling the movement of the vehicle parking device, and the vehicle parking device Vehicles. Background technique [0002] Because the parking device directly acts on the gear shaft of the transmission, it has higher safety and longer service life, so it is more and more applied to existing vehicles. In the existing parking devices, most of them include the parking gear fixedly connected with the transmission gear shaft, the parking pawl, and the driving mechanism for driving the parking pawl. The driving force is applied to the parking pawl by the driving mechanism, so that The parking pawl meshes with the parking gear to realize parking. When the parking state is released, the driving force of the driving mechanism on the parking pawl is rel...
