The principle of the reverse gear is to add an additional gear between the driving gear and the driven gear. In other words, gears 1 to 5 are forward gears driven by two gears, while the reverse gear is driven by a single gear. Below is an introduction to reversing: 1. Introduction: Reversing refers to the backward movement of a motor vehicle. It also refers to the act of "transferring" during travel, i.e., switching from one vehicle to another. Reversing is more challenging than driving forward, mainly due to limited visibility. 2. Four hazards to prevent: Collision prevention: When shifting in reverse, pay attention to the width of the target position and assess the obstacles behind and on both sides of the vehicle relative to the safe position of the rear wheels. To avoid collisions, scrapes, or falling into ditches, it may be necessary to have someone guide the vehicle from behind. Garage scrape prevention: When reversing into a garage, if visibility is good, you can directly observe and judge through the rear window. If visibility is poor and you cannot see clearly, open the door and assess the position of the vehicle in the garage from one side while also checking the other side through the rearview mirror to prevent scraping the garage or other vehicles. Side scrape prevention: When reversing around a corner, pay attention to the situation on the inside of the turn and behind the vehicle. Use the rearview mirror to monitor both sides of the vehicle and time the steering wheel correctly to avoid rear-end collisions or side scrapes. Ditch fall prevention: When reversing to turn around, if the road is wide enough, you can judge the position of the rear or wheels directly through the rearview mirror. If multiple forward and reverse movements are needed, step out to check the safe distance between the wheels and the road to prevent falling into a ditch.

What to Do When the Tire Pressure Warning Light Comes On?

Tire Pressure Warning Light comes on for the following reasons and solutions: 1. Punctured tire: If the tire is punctured and air leaks slowly, drive at low speed to the nearest repair shop for treatment. Do not pull out the nail immediately, as it may cause more severe air leakage, making the car unable to continue driving. 2. Long-distance driving: Prolonged driving increases tire temperature, leading to higher tire pressure and triggering the warning light. In this case, you can stop and wait for the tire temperature to cool down naturally before continuing, or switch to a spare tire. 3. Lack of tire pressure maintenance: If the issue is due to prolonged lack of tire pressure, use an onboard air pump to inflate the tire to the normal range for regular driving.

What Causes Difficult Gear Shifting on Motorcycles?

Difficult gear shifting on motorcycles can be attributed to the following reasons: 1. Clutch: The clutch transmits and cuts off the power from the engine to the transmission, acting as a buffer in the power transfer process. A properly functioning clutch ensures smooth gear shifting. If the clutch does not disengage completely, it can lead to difficulty in shifting gears. 2. Transmission: The transmission consists of components such as the shift drum, shift forks, main and countershafts, transmission gears, star-shaped gear (five-point gear), and shift shaft. Wear and tear on any of these components can cause gear shifting issues. Note: If the issue is not related to the clutch, inspect the star-shaped gear (five-point gear) and shift shaft. These two components are more prone to failure in actual maintenance scenarios. If these components are functioning properly, the transmission may need to be disassembled for further inspection.
