AI Technical Summary

Technical Problem

The existing parking devices are difficult to effectively absorb rebound energy when facing complex execution conditions, resulting in damage to the actuator and insufficient mechanical strength, making it difficult to meet the needs of high mechanical strength.

Method used

A parking device is designed, including parking gears, parking pawls, drives, actuators and limiting parts. The limiting member is arranged at the end of the return stroke of the actuator to limit the return stroke of the actuator and uses high-strength alloy structural steel material. The push rod mechanism adopts an integrated push bracket and a drive rod design. The fixed pin installs the double rollers on the push bracket and sets an anti-turn limit structure.

Benefits of technology

It effectively prevents the actuator from being damaged due to rebound, improves the mechanical strength and reliability of the parking device, can absorb rebound energy, and extends service life.

Abstract

The utility model provides a parking device which comprises a parking gear, a parking pawl, a driving piece, an executing piece and a limiting piece. The limiting piece is arranged at the return stroke tail end of the executing piece and used for limiting the return stroke of the executing piece, the situation that an executing mechanism is damaged or fails due to stress springback is prevented, the limiting piece can be made of alloy structural steel, the mechanical strength of the parking device can be improved, and springback energy can be effectively absorbed; a push support and a drive rod in the push rod mechanism are designed to be of an integrated structure, assembly is easy, the integration degree is higher, and the risk of assembly looseness caused by stress in the using process is reduced; according to the parking device, the double rollers are installed on the pushing support through the fixing pins, the situation that the fixing pins rotate, loosen and the like under the stress condition is effectively prevented by arranging the anti-rotation limiting structures, the service life of the parking device is further prolonged, and the reliability of the parking device is further improved.
