What is the Difference Between Spiral Gears and Helical Gears?

The following are the differences between spiral gears and helical gears: 1. Definition: Spiral gear transmission consists of two helical gears meshing together, used to transmit motion between two intersecting axes in space. Helical gears are not entirely spiral gears; spiral gears refer to the meshing method of two helical gears, distinguished by the different directions of force transmission in space. 2. Operation: For a gear pair, a helical gear mechanism refers to parallel axis transmission. In contrast, the axes of a spiral gear mechanism are not parallel and intersect in space. 3. Conditions: The meshing condition requires equal normal modules, and there is no requirement for the spiral angle to be "equal in size and opposite in direction," thus the center distance calculation differs.

Is driving on the highway tiring without cruise control?

Whether with or without cruise control, driving on the highway for extended periods can be tiring. Here are detailed explanations about it: 1. Explanation one: Fatigued driving is highly likely to cause traffic accidents. It refers to the phenomenon where drivers experience physiological and psychological dysfunction after prolonged continuous driving, resulting in objectively diminished driving skills. 2. Explanation two: Drivers with poor or insufficient sleep quality are prone to fatigue due to a lack of endogenous oxygen during long hours of driving. 3. Explanation three: The new traffic regulations impose stricter penalties for fatigued driving. Once caught for fatigued driving, 12 points will be deducted from the driver's license.

You can take the Subject One test without removing your mask. Subject One, also known as the Subject One theory test or driver's theory test, is part of the motor vehicle driver's license examination. The content of the Subject One test covers traffic regulations and related knowledge, including the theoretical basis of driving, road safety laws and regulations, local regulations, and other relevant knowledge. Below is an introduction to the content of the driving test subjects: 1. Subject One: The road traffic safety laws, regulations, and related knowledge test (Subject One) is a written test conducted on a computer, with a full score of 100 points. A score of 90 or above is considered passing (including 90 points). 2. Subject Two: The field driving skills test (Subject Two) is conducted in a designated area using an actual vehicle. The results are only categorized as pass or fail. The test includes five mandatory items performed in sequence: reversing into a parking space, parallel parking, S-curve driving, right-angle turning, and starting and stopping on a slope. The full score is 100 points, with 80 or above considered passing (including 80 points). 3. Subject Three: The road driving skills test (Subject Three) is conducted on a highway or simulated field using an actual vehicle. The full score is 100 points, with passing scores varying by vehicle type: 90 or above for large buses, 80 or above for large trucks, and 70 or above for other vehicle categories. 4. Subject Four: The safe and civilized driving-related knowledge test (Subject Four) is a written test with a full score of 100 points. A score of 90 or above is considered passing (including 90 points).

What are the techniques for reverse parking?

Techniques for reverse parking are as follows: 1. Parking skills: The main points for deduction in reverse parking include pressing the line, the car not entering the garage, overtime, and not driving according to the prescribed route. After the new regulations reform, reverse parking has added a time limit, which must be completed within 210 seconds. Overtime results in disqualification. During the test, first reverse to the right, then to the left. Not following the sequence will result in disqualification. Pay attention to the 30cm margin issue when reversing. 2. Parking skills: The main points for deduction in parallel parking include the turn signal, 30cm margin, and pressing the line. When entering the test area, turn right in advance and observe the highest point of the wiper coinciding with the roadside line to adjust the 30cm margin. When reversing, remember the first right turn point, straighten, turn left to the end, park in the garage, turn on the left turn signal, and observe the rearview mirror when exiting to prevent the wheels from pressing the line on both sides. 3. Turning skills: The main points for deduction in right-angle turning include the turn signal and pressing the line. After entering the test area, turn on the turn signal. After the voice prompt, turn off the turn signal. Incorrect operation of the turn signal will deduct 10 points. After entering the right-angle turn, adjust the body and the 30cm margin of the side line. The viewing point is the same as parallel parking. When turning to the end, you can slightly loosen the clutch to prevent stopping or stalling midway. After the rear wheels exit the garage, straighten the body to prevent the wheels from pressing the line.
