  • To ensure the normal operation of the drive shaft, drive shaft extending its life, in use should be noted:

    1. Prohibited the car started with high gear.

    2. Meng lift the clutch pedal is strictly prohibited.

    3. Non-automotive overloading, speeding.

    4. You should always check the shaft working conditions.

    5. Should regularly check the drive shaft hanger fastening, whether supporting rubber damaged the connecting shaft parts are Songkuang, drive shaft is deformed.

    6. In order to ensure the balancing of the drive shaft, should always pay attention to whether the sealing off balance sheet welding. The new drive shaft assembly is supporting the provision, should pay attention to the new loading telescopic shaft assembly marks, should ensure that the flange fork in a plane. Disassembly during maintenance shaft should be kept constant during the original assembly relationship telescopic shaft and flange assembly marking print, to prepare for re-assembly.

    7. Should often universal joint cross bearing lubrication, summer should be injected into the 3rd lithium grease, winter inject the 2nd lithium grease.



  • In the car started before, the natural first start the engine. The car started, the car is completely stationary state from the gradual acceleration. If the drive system (which links the entire vehicle) rigidly contact with the engine, the transmission is in gear a car will suddenly look forward, but it does not start. This is because the car from a standstill to pediment, have a great inertial force, causing the engine drag torque greatly. In this moment of inertial resistance effect, a sharp decline in the blink of time the engine speed to the minimum stable speed (usually 300-500RPM) or less, that is, the engine stalled and can not work, of course, cars can not be started.

    After engine start, before the car started, the driver first depresses the pedal way starter, the starter-way separation, the engine and drive train is disengaged, then the transmission is in gear, and then gradually release the starter unidirectional pedal, so that way starter gradually engaged. In the bonding process, the engine torque is increased gradually blocked, it should also gradually depress the accelerator pedal, the gradual increase in the amount of fuel supplied to the engine, the engine's speed is always maintained at a minimum stable speed, and will not turn off. Meanwhile, the way starter engagement tightness increases, the engine torque transmitted to the drive wheels via the transmission line will be gradually increased, to the traction force sufficient to overcome the initial resistance, car starts moving from standstill and gradually accelerate 2, to ensure a smooth way starter at work driveline shift can be divided into: Friction way starter or the use of liquid as the transmission medium (ie hydraulic coupling), or the use of magnetic transmission (ie, single solenoid starter to implement way starter drive must conditions:

    (1) engages splines modulus same pressure angle drive gear and armature assembly keyway on the inner mandrel way starter.

    (2) outside engaging way starter and diesel flywheel ring gear teeth modulus same pressure angle.

    (3) When changing way starter, because no replacement starter armature assembly mandrel and diesel engine flywheel ring gear, so check the tooth inside and outside the pitch circle diameter must be replaced with the same way starter.

    Due to the current production of automotive electrical manufacturer specifications starter one-way model is not unified, the replacement way starter, to satisfy the above conditions, only the same manufacturers produce the same type of one-way only interchangeable.

    Therefore, under normal circumstances, different manufacturers produced way starter are not interchangeable.

  • 1, to ensure a smooth start car

    This is the primary function of the clutch. In the car started before, the natural first start the engine. The car started, the car is completely stationary state from the gradual acceleration. If the drive system (which links the entire vehicle) rigidly contact with the engine, the transmission is in gear a car will suddenly look forward, but it does not start. This is because the car from a standstill to pediment, have a great inertial force, causing the engine drag torque greatly. In this moment of inertial resistance effect, a sharp decline in the blink of time the engine speed to the minimum stable speed (usually 300-500RPM) or less, that is, the engine stalled and can not work, of course, cars can not be started.

    Therefore, we need the help of the clutch. After engine start, before the car started, the driver first depresses the clutch pedal, the clutch, the engine and drive train is disengaged, then the transmission is in gear, and then gradually release the clutch pedal, the clutch is gradually engaged. In the bonding process, the engine torque is increased gradually blocked, it should also gradually depress the accelerator pedal, the gradual increase in the amount of fuel supplied to the engine, the engine's speed is always maintained at a minimum stable speed, and will not turn off. Meanwhile, the tightness of clutch engagement increases, the engine torque is transmitted to the drive wheels via the transmission line will be gradually increased, to the traction force sufficient to overcome the initial resistance, car starts moving from standstill and gradually accelerate 2, to ensure drivetrain swap slotting work smoothly

    2, to achieve a smooth shift

    In the car driving process, in order to adapt to changing driving conditions, drive train often work to replace the different stalls. Shift the gear type transmission, or other generally toggle gear-gear mechanism, to allow use of a gear transmission gear pair launched, then make another shift gear pairs into the work. In the clutch pedal before shifting to interrupt power transmission, facilitates engaging former deputy disengaged gear, while the speed of the new gear engaged with the engagement portion of gradually becoming deputy synchronized into the impact of such engagement can be greatly reduced, to achieve smooth shifting.

    3, to prevent transmission system overload

    Issued when the vehicle is braked, if no clutch, the engine and the drivetrain will vary sharply reduce rigid connection speed, and thus where all the moving parts will have a great moment of inertia (its value may be much higher than normal engine work The maximum torque), causing the drive system load exceeds its capacity, leaving mechanical damage. With the clutch, the clutch can rely on the active part and the relative movement may occur between the driven part to eliminate this risk. Therefore, we need to limit the maximum torque clutch transmission system is subjected, and ensure safety.

  • Electric start clutch (also known as one-way) clutch, also known as 'highly son', is the vehicle engine to transfer to the device switches manner on the axle. Gasoline engine powered vehicles running, the engine continues to run.

    But in order to meet the demand on cars, the vehicle must stop, shift and other actions, it is necessary to move them outside even at the engine, added a mechanism to interrupt transmission of power depending on demand, as with the case of the engine continues to run By reaching so that the vehicle is stationary or gear shift operation. This group of institutions, that is, the power connection devices. This group of institutions is device clutch between the engine and manual transmission, is responsible for transmitting power of the engine gearbox hand.

    When the clutch pedal is released, the pressure plate flywheel inside using the power of the spring, tightly pressed against the friction plate, so that in between the two are not linked slip phenomenon, achieve the purpose of the connection, and power of the engine will be able through this a mechanism, is transmitted to the gearbox, power transmission is completed job. When the pedal is pressed, will spring loaded mechanism, making the surrounding tilt of the spring, the pressure will be off and the skin friction plate.

    At this point of friction between the plate and the flywheel has been unable to even move, even if the engine continues to run, the power is still not transmitted to the gearbox and wheel, this time, the driver can shift gears and stop other actions, and will not make the engine flameout .

  • Also known as a one-way one-way filters, one-way isolator. It is from the microwave device - on the principle of developing the circulator up specifically for radio paging transmitter design, with energy absorption from outside interference signals enter the transmitter through the antenna system, as well as protect the transmitter to reduce the failure rate Features.

    Unidirectional filter by a precision sintered and ground gyromagnetic constant magnetic decorated with microstrip inductors, capacitors, resistors, and other components coupled to the cavity resonance, the filter circuit. The rotating magnetic field, the electromagnetic wave signal having a one-way transfer of properties. Signal rotate 120 degrees almost no damage from the output terminal out; the external signal from the output terminal to enter, with the direction of rotation of 120 degrees into the absorbent end turns into heat energy dissipated (see Figure 4).

    Unidirectional filter electrical characteristics: Requires forward insertion loss is very small, less than 0.3∽0.5dB; and the reverse feature requires greater the energy absorbed, the more bandwidth the better the frequency required in the 20MHz bandwidth and can reduce energy than 25dB . So, there is a one-way filter to absorb an interference signal at the transmitter frequency around the main entry from outside intrusion, as well as suppression of intermodulation products function.

    Check the technical indicators are mainly three:

    (1) Forward Insertion Loss

    Plus one-way transmitter, it will lose power 0.3∽0.5dB (for 100W transmit power for about 7∽10W).

    (2) reverse isolation and reverse isolation Bandwidth

    This indicator refers to the ability to absorb external interference signals, SRRC of Ⅱ class standards should be better than the center frequency fo ± 10MHz bandwidth within 25dB, within fo ± 5MHz bandwidth is better than 30dB.

    Ⅲ class one-way dual ends (ie, the composite made of two one-way), which can be done within the index fo ± 10MHz bandwidth than 40dB, and fo within ± 5MHz bandwidth than 50dB. Because of the relatively large insertion loss (insertion loss of two one-way), users do not want to accept.

    (3) VSWR

    VSWR is to evaluate whether the matching unidirectional interface to an important indicator. Less than 1: 2: 1, well less than 1: 1: 1. That is when the 100W transmit power, reflected power less than 0.8W.
