The clutch of my truck is not clean, and what is the reason why the clutch suddenly runs out of the

The clutch, as the name suggests, is to play the role of disengaging and closing. That is, it plays a role in the separation of the engine and the wheel transmission device. That is to say, when you press the clutch, then the transmission of the engine is disconnected from the wheels, and the power of the engine is not transmitted to the wheels to drive the car.

When you release the clutch, the transmission of the engine is connected to the wheels, and the power is transmitted to the wheels, and the car will naturally move. So why separate the power from the wheels? Because the engine at different speeds has to be shifted, this problem is more complicated, I will ominously elaborate, in short, the transmission device of the engine at different speeds should transmit different speeds to the wheels, and at this time, it is necessary to separate the slow gears from the wheels, and use the high-speed gears to engage the wheels

Before changing the master pump, the first suspicion was that the air was not exhausted. At the same time, the master cylinder push rod is adjusted too short and the free stroke of the pedal is too large, which will cause the master pump to supply less oil.

Clause. Second, the clutch jumps too low, the push rod of the sub-pump is adjusted too short, and the release bearing is too far from the clutch disseparator claw, so that more feet are needed to have enough oil to push the piston of the sub-pump to have enough stroke to achieve separation.

The reasons for the incomplete clutch separation are that the clutch plate is worn and warped, and the sub-pump is not discharged.

There is air in the clutch line. If the clutch gap is not jumped well, the tension spring on the clutch cylinder will be permanently deformed. It really can't be done, so you can only adjust the master pump to get a free stroke. I've been fixing the car for five years. That's all I can tell you.

Summary. The reasons why the truck suddenly lost its clutch during operation are: 1The clutch master cylinder or sub-cylinder is broken.

2.The clutch actuator cylinder hydraulic oil leaked.

3.If it gradually disappears in the process of use, it means that the clutch plate is worn.

What is the reason why the truck suddenly lost its clutch in operation.

The truck suddenly lost its clutch in the running beam and the reasons are: 1The clutch master cylinder or rubber sub-cylinder is broken.

2.The clutch actuator cylinder hydraulic oil leaked. 3.

If it gradually disappears in the process of use, it means that the clutch plate is worn.

<> hope mine can help you, thank you, and have a nice ride!

There are many reasons why the clutch of the truck does not separate, which may be as follows: 1. It may be caused by the bending and deformation of the separation lever, the loosening of the bearing, and the detachment of the bearing axle pin, which makes it difficult to adjust the height of the inner end of the separation lever; 2. The inner end of the separation lever is not in the same plane, or the height of the inner end is too low; 3. The limiting screw of the clutch intermediate pressure plate is improperly adjusted, and the individual separation spring is fatigued, the height is insufficient or broken, resulting in the intermediate pressure plate on the transmission pin, or the axial movement is inflexible in the clutch drive window.

Hello dear, <>

I am glad to answer for you, the main reasons for the truck clutch heavy truck are that the length of the front pressure plate spring is relatively different from the stiffness or damaged, the hole depth of the spring is unequal, and the inner and outer clutch disc assembly is warped, the rivet is loose, etc., resulting in the radial circular runout of the clutch assembly and the full runout of the end face exceeds the regulations, so that it is in intermittent contact state. Check the free stroke of the hydraulically operated clutch pedal and adjust it to the specified range. (The free stroke of the hydraulically operated clutch pedal is composed of two parts: the clearance between the piston and the pushrod of the main cylinder and the clearance between the inner end face of the release lever and the release bearing.)

The stroke is adjusted by changing the length of the piston pushrod of the working cylinder). <

What to do if the clutch of the truck is too heavy The clutch is too heavy because the linkage mechanism of the clutch is too dirty or corroded, remove the clutch mechanism for cleaning and maintenance, replace the oil injection that needs to be replaced, and adjust the clearance according to the standard. The solution of the truck clutch weight: 1. Adjust the push rod of the clutch assistant pump, on the side of the transmission, the method is very simple, first loosen the solid Zheng of the rod which nut, and then rotate the collapse of the bush to suspect the push rod (after the fixed nut is released, the push rod is movable and can be rotated in time and counter-time), see the rod become longer and shorter, and the pressure rod should be pressed back in the direction of the pressure plate, and the gap can be felt, if not, the push rod will be shortened.

Sometimes if method 2 is not adjusted, you can only adjust the assistant, generally the larger the gap, the lower the clutch, the smaller the gap, the higher the clutch); 2. Adjust the clutch master cylinder, under the clutch pedal, when the use method 1 is adjusted appropriately, if the test is too high or too low, you can first see if there is a tune under the master cylinder; 3. The same principle is that the master pump is also a push rod, which is low on the pedal, and there is also a fixed nut, as long as it is loosened, the rod can be shortened or shortened, and the general pump is generally loose and the clutch will be high. @2019

Manual transmission vehicles need to use the clutch function in order to gear the vehicle, some owners react, the clutch pedal of the vehicle has been released, the vehicle still does not go, so the clutch is put why the car is not gone?

1. In this case, the handbrake function of the vehicle may be open, braking the rear wheel of the vehicle, so that the owner lifts the clutch pedal, and the vehicle still does not go, in this case, only the handbrake of the vehicle needs to be released.

2. The gear clearance of individual vehicles is large, or it may be that the owner is not fully in gear, after releasing the clutch, the vehicle is still in neutral mode, and the owner can try to re-gear and drive the vehicle.

3. It is also possible that the clutch of the vehicle is faulty, such as the clutch is not closed in place, or the clutch plate is damaged, so that the vehicle can not be properly geared, in this case, it is necessary to go to the automobile repair factory to repair the clutch closed riser of the vehicle.

When the owner uses the vehicle, he should pay attention to the correct use of the clutch of the vehicle to prevent the clutch car of the vehicle from malfunctioning, affecting the owner's travel plan.

2) The separation lever is bent and deformed, the support is loose, and the bearing axle pin is out of place, which makes it difficult to adjust the height of the inner end of the separation lever.

3) The separation lever is not properly adjusted, its inner end is not in the same plane or the inner end height is too low.

4) The limit screw of the intermediate pressure plate of the double-plate clutch is not properly adjusted, the individual separation spring is fatigued, the height is insufficient or broken, and the intermediate pressure plate is not flexible on the transmission pin or the axial movement in the clutch drive window.

5) The driven disc steel sheet is warped, the friction plate is cracked or the rivet is loose.

6) The new friction plate is too thick or the front and back of the driven disc are wrongly installed.

7) The spline hole of the driven disc is stuck with the spline shaft of the first axis of the transmission.

8) The clutch hydraulic control mechanism leaks oil, there is air or the oil volume is insufficient.

9) Weakened elasticity of the diaphragm spring.

10) The engine support is worn or damaged, and the engine is not concentrified with the transmission.

Diagnosis and exclusion.

1) Check the clutch pedal free travel and adjust it if the free travel is too large. Otherwise, for the hydraulic control mechanism, check whether the oil volume of the liquid storage tank is insufficient or there is air in the pipeline, and carry out the necessary elimination. If it is not the above question, you should continue to check.

2) Check the height of the inner end of the separation lever and adjust it if the separation lever height is too low or not in the same plane. Otherwise, check whether the driven disc is reversed, and if it is all right, continue to check.

3) Check whether the driven disc is warped and deformed, the rivet falls off, and whether the driven disc is stuck in the axial movement, etc., and if so, replace or repair it.

Summary: The incomplete clutch separation can mainly be considered from several aspects such as the free stroke of the clutch pedal, the height of the release lever, and the driven disc.
