What is the composition of a differential?

1 Answers

07/25/25 12:33pm

The differential is composed of left and right axle gears, two planetary gears, and a gear carrier. The differential is a mechanism that allows the left and right or front and rear drive wheels to rotate at different speeds. The main function of the differential is to enable the left and right wheels to roll at different speeds when the car is turning or driving on uneven roads, ensuring that both drive wheels perform pure rolling motion. The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive systems, to drive all four wheels, they must be connected. If all four wheels are mechanically connected, the car cannot rotate at the same speed when driving on curves. To ensure that the car's rotational speed is basically consistent during curve driving, a center differential is added to adjust the speed difference between the front and rear wheels.

Where to Apply for a Vehicle License?

Vehicle licenses are processed at the local vehicle management office nearest to you. The vehicle license is issued when registering the motor vehicle. Required materials for application: 1. Original copy of the 'Motor Vehicle Registration, Transfer, Cancellation/Import Application Form'. 2. Original and photocopy of the vehicle owner's identity proof. 3. Proof of origin for the motor vehicle. 4. Original copy of the domestic motor vehicle's whole vehicle factory qualification certificate; original copy of the 'Goods Import Certificate' for imported motor vehicles. 5. Proof of payment for vehicle purchase tax or tax exemption certificate. 6. Proof of compulsory traffic accident liability insurance for motor vehicles. 7. Proof of payment or tax exemption for vehicle and vessel tax.

How many kilometers should the PCV valve be replaced?

Replace the PCV valve at 120,000 kilometers. Main function: It directs the gases from the crankcase into the intake manifold through the PCV valve, with a small amount of air entering the intake manifold directly from the air filter via the PCV valve. This prevents phenomena such as icing at the throttle, incomplete combustion, and worsened emissions. Symptoms of a faulty PCV valve in the engine: 1. Engine shaking, unstable idle, and a large amount of white smoke from the exhaust pipe. 2. It may cause oil to remain in the crankcase, leading to corrosion, accelerated wear, and shortened engine life. 3. It can also cause difficulties in starting the engine, idle shaking, lack of power during acceleration, and excessive oil consumption. 4. It is prone to sludge deposits and clogging, which increases the pressure inside the crankcase, causing oil vapors and exhaust gases to flow back into the air filter and contaminate the air filter element.

How often should the coupling oil be changed?

Coupling oil should be changed every three years. Here are the precautions for coupling oil filling: 1. Oil type: Usually, non-flammable hydraulic oils such as No. 8 hydraulic oil or No. 32 hydraulic oil are used, and gear oil must not be added. Oil filling is strictly prohibited in hydraulic couplings (except for adjustable-speed hydraulic couplings), as it may cause explosions or fires. 2. Oil filling amount: The filling amount should be 70%-80%. For ordinary torque-limiting hydraulic couplings, the filling amount corresponds to 80% of the rated power. Tilt the oil filler at a 45° angle from the vertical direction, and fill until the oil just starts to flow out. Typically, the filling range for YOX-type couplings is 40%~80%.

What does the turning dotted line mean?

Turning dotted line means turning guide line. The following is the specific introduction of road markings: 1. White solid and broken line: When the broken line is in the middle of the road section, its function is to separate the traffic flow in the same direction or as a line for identifying safe driving distance. When at an intersection, its function is to guide the vehicle forward; When the solid line is in the middle of the road section, its function is to separate motor vehicles and non-motor vehicles traveling in the same direction, or to indicate the edge of the lane. When at an intersection, its function is as a guide lane line or stop line. 2. Double white solid and broken line: When the broken line is in the middle of the road section, its function is as a variable lane line whose driving direction changes over time. When at an intersection, its function is as a yield line. The function of the solid line at an intersection is as a stop line.

Why does the turn signal not automatically reset?

Turn signals not automatically resetting is due to damaged positioning pins. Here is additional information: 1. Turn signals: Turn signals are the primary devices indicating a vehicle's dynamic information, installed at the front and rear of the car body. They are activated when the car turns, providing safety for driving. Proper use of turn signals allows drivers to anticipate the car's movements in advance and make correct judgments. 2. Turn signal tubes: Turn signal tubes use xenon tubes with a microcontroller-controlled circuit, enabling alternating left-right flashing without interruption. Turn signals employ flashers to achieve light blinking, mainly categorized into resistance wire type, capacitor type, and electronic type.

What Causes a Scooter to Stall When Accelerating After Starting?

Here are the reasons why a scooter stalls when accelerating after starting: 1. Idle speed too low: This causes the air-fuel mixture to become too lean when accelerating due to a sudden increase in air intake, making it unable to ignite and resulting in stalling. In this case, you can adjust the idle speed appropriately. If your motorcycle's idle speed is normal, this reason can almost be ruled out. 2. The choke switch is not closed before cold starting: Accelerating under this condition can also cause the engine to stall. If your motorcycle's choke switch is not open, this situation can also be ruled out. 3. Carburetor fuel supply issues: Such as a clogged fuel filter or a damaged float chamber switch causing poor fuel supply. When accelerating, the fuel level in the carburetor float chamber drops, but the subsequent fuel supply cannot keep up, leading to stalling. This type of fault usually results in a brief increase in RPM when accelerating, followed by stalling.
