What is the difference between parking gear and handbrake?

[FelixRose]

The difference between parking gear and handbrake is that the P gear is the parking gear. After engaging the P gear, the output shaft of the transmission is locked, which means the input shaft of the tires is mechanically locked inside. It can be simply understood as parking with the gear engaged in a manual transmission, while the handbrake purely brakes the tires through something similar to brake pads. Below are the specific introductions to parking gear and handbrake: 1. Parking gear: The P gear is evolved from the N gear. Besides setting the transmission to neutral mode, there is also a pawl inside the transmission that locks the gear on the output shaft to form a mechanical lock, thus securing the drive axle to fix the vehicle in a stationary or slightly moving state. 2. Handbrake: The professional term for the handbrake is auxiliary brake. Different from the principle of the brake, it uses a steel wire cable connected to the rear brake shoe to brake the vehicle. Long-term use of the handbrake will cause plastic deformation of the steel wire. Since this deformation is irreversible, long-term use will reduce its effectiveness, and the travel of the handbrake will also increase.
