Transmission parking system and method of using the transmission parking system

Abstract

The invention provides a transmission parking system and a transmission parking system use method and relates to the technical field of automobile braking systems. The transmission parking system comprises a parking ratchet, a parking pawl and a time-delay mechanism. The parking ratchet meshes with the parking pawl. The time-delay mechanism is connected to the end, away from the parking ratchet, of the parking pawl and is used for pressing the parking pawl, or the time-delay mechanism is connected to the end, close to the parking ratchet, of the parking pawl and is used for lifting the parkingpawl, so that the parking pawl is arranged in the direction away from the parking ratchet under the action of the time-delay mechanism. The technical problems that in the prior art, when an automobile is operated from a D gear or an R gear to a P gear, a parking pawl and a parking ratchet are completely attached to bear force due to overturning of a power assembly, and the driving feeling of a driver is influenced are solved. The time-delay mechanism of the transmission parking system can provide certain acting force for the parking pawl, and the time need by meshing of the parking pawl and the parking ratchet is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile parking systems, in particular to a transmission parking system and a method for using the transmission parking system. Background technique [0002] The automatic transmission of a car is a car transmission that can automatically change the gear ratio while the vehicle is running. It is commonly divided into four types: hydraulic automatic transmission, mechanical continuously variable transmission, electronically controlled mechanical automatic transmission and dual clutch. Automatic Transmission. Among them, the hydraulic automatic transmission is a commonly used automatic transmission. The gear positions of the automatic transmission are divided into P, R, N, D, 2, 1 or L, etc., among which the P gear is used for parking to prevent the car from accidentally starting in other gears and causing the car to suddenly move forward and cause danger. status. The parking function of the hydraulic...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a transmission parking system to solve the problem in the prior art that when the car is shifted from the D gear or the R gear to the P gear, the parking pawl and the parking ratchet caused by the overturning of the powertrain Completely close to the force and affect the technical problems of the driver's driving experience

[0006] The present invention also provides a method for using the transmission parking system to solve the problem in the prior art that when the car is shifted from the D gear or the R gear to the P gear, the parking pawl and the parking gear caused by the overturning of the power assembly The ratchet is fully attached to the force, which affects the technical problem of the driver's driving experience
