What is the function of a synchronizer?

1 Answers

The main functions of a synchronizer are: 1. To enable the gears about to mesh to reach the same rotational speed for smooth engagement, allowing the synchronizer sleeve and the gear ring preparing to mesh to quickly synchronize, and preventing engagement before synchronization is achieved. 2. To make the car run more smoothly, enabling the transmission synchronizer sleeve and the gear ring to be engaged to synchronize quickly, shortening the shifting time, and preventing shifting impact caused by engagement before synchronization. 3. To solve the problem of the engine speed and the transmission speed being different during gear shifting operations, effectively avoiding failure to engage gears and eliminating gear noise during shifting. There are two types of synchronizers in the transmission: one is the three-piece synchronizer, and the other is the single-piece synchronizer.

What Causes Brake Pad Noise When Not Braking?

Reasons for brake pad noise when not braking: 1. The brake pads may be installed incorrectly. Upon removal, you can see that only part of the pad surface shows signs of friction. In this case, visit a 4S shop to have them removed and reinstalled properly. 2. Road debris may have gotten stuck between the brake pads while braking. This can be resolved by cleaning at a 4S shop. 3. Larger brake pads installed on a brake disc previously used with smaller pads. This requires resurfacing the disc or driving for a while until the friction marks align, eliminating the noise. 4. Poor-quality or overly hard brake pad material. In this case, the only solution is to replace them with new pads.
