How to prevent frustration when shifting gears in manual gears

The reason for the shift frustration is the mismatch of the speed before and after the shift, and one of the solutions is to minimize the shift time, and before the speed drops, you have already shifted the gear to complete the clutch re-engagement. On the other hand, if you don't shift fast enough, then you have to learn to replenish the oil, before the clutch is lifted after shifting (the clutch is fully stepped on), make up for a foot of oil, usually upshift to make up a little less, downshift to make up a little more, and the specific needs to match the speed of the car, and you can feel it when you are proficient. The principle is simple, just bomb the revs to near the revs before the shift before the clutch is re-engaged.

In fact, it is difficult to avoid the frustration of the manual transmission, don't care so much, as long as it is not a huge frustration. The common 5MT gear gear ratio drop is relatively large, especially the first 3 gears, which is very normal, or you take a taxi to experience. I think the impact of a bang, a knock is good and comfortable.

If you want to start fast, then you have to step on the accelerator to start with the clutch, the general car you start with a gear of 2500rpm clutch (step on the clutch, hang a gear, step on the accelerator speed to 2500rpm, steady, clutch don't loose, and wait for you to confirm that it is safe to start, half of the clutch bullet (quickly put it to the half-linkage point), and then your car will pop out) is enough, because you also have to pay attention to the safety in the intersection, or beware of the sudden sudden braking of the car in front. Of course, if you are going to test zero hundred acceleration, 3000-4000rpm just pedal, and then full of clutch. In short, novices should use with caution, and use with caution in places with complex road conditions.

Nowadays, there are more and more people who can drive, and for those who drive manual cars, manual models can bring a certain driving experience, but many people will encounter such a situation when driving, after the car starts smoothly, the reason why most vehicles trip is basically because the engine speed does not match the speed when we shift gears and press the clutch. It's easy to feel frustrated when the engine speed is lower than the engine speed.

Because the demand for torque output at the front end of the power chain, and the subsequent drilling and torsion, can almost match. This method is usually used on high-speed roads or when the road surface is relatively flat. This is the easiest way to fully coordinate the torque between the front and rear ends of the transmission by loosening the clutch.

It's also the easiest way to avoid jitter throughout the gear chain. It perfectly coordinates the torque between the front and rear ends of the transmission. Before changing gears, press the accelerator pedal steadily according to the road and traffic conditions, and gradually increase the speed of the vehicle.

This process is called a "sprint".

When the speed is suitable for hanging the gear, immediately press the accelerator pedal, press the clutch pedal, and move the gear lever to the neutral position; Immediately depress the clutch, then quickly depress again. At the same time, shift the gear lever to a higher gear. While lifting the clutch pedal, slowly press the accelerator pedal to keep the car running smoothly.

Depending on the situation, use the same method to move to a higher gear. When the vehicle is driving, as long as the road conditions and traffic conditions allow, it should be hung in time. Before shifting gears, you have to accelerate the "sprint" to make sure you have enough power to keep the car running smoothly after shifting.

If the "sprint" is too small, it will lead to a lack of power and jitter after shifting; If the "emergency stop" time is too long, the engine will run at high speed for a long time, which will increase wear and reduce economy. The timing of the upshift should be determined according to the sound, speed and power of the engine.

It may be because the clutch pedal is not well controlled when the manual transmission car shifts, and when changing gears, if the clutch pressure plate and the clutch are in gentle contact, his frustration will be slightly lighter, or if there is a frustration, it may be that the cycling transmission oil needs to be changed, or it may be because the transmission oil cannot lubricate the gears.

It is normal for a car with a manual transmission to have a sense of frustration in shifting, and the first and second gears are more noticeable when starting. This comes from the force that comes out of the moment the clutch plates are combined.

This situation is caused by the bending of the pressure plate of the gearbox, and it is only necessary to replace the pressure plate with a new one.

1.Adjust the shift speed:

Shift gears at 1500 rpm. For engines with large displacement or good low-speed torque, it is even possible to shift gears at low speeds of 1000-1200 rpm without stumbling, which has little impact on speed. Therefore, riders who often experience frustration in shifting gears can try adjusting (decreasing) the engine speed when shifting gears to find an engine speed that can shift smoothly without affecting the acceleration.

2.Adjust the gear order:

The standard schedule is progressive, i.e. 1-2-3-4-5. In some cases, a stutter can also be avoided if a jump gear is used, such as when the engine speed of the 2nd gear is increased to 2000rpm, you can directly shift to 4th gear, and 3rd gear can be directly shifted to 5th gear. This is based on the principle that the front output torque and rear torque requirements of the powertrain are roughly matched.

It is usually used more when accelerating on highways and on flat roads.

If the previous two-foot shift method (first press the clutch to reverse and then press the clutch to upshift) has a long shift time, it will cause the engine speed to be too high and frustrated. The one-kick method (continuous reverse gear and clutch upshift) can shorten the overall shift time, and the engine speed can be reduced even less, avoiding reversing.

4.Gently press the throttle when shifting the ruler to send a group:

When you step on the throttle when shifting gears, the engine easily spins empty at high speeds. If you don't step on the accelerator, the engine speed drops too fast and you will trip. For vehicles with slightly worse engine torque at lower engine speeds, the throttle can be lightly grasped when shifting, which will not cause high-speed idling and avoid the frustration caused by slowing down too quickly.

The frustration of manual gear shift is caused by the poor coordination of oil and clutch when the owner operates the gear shift. If the engine speed is not synchronized with the clutch speed, it will cause impact between the transmission parts, resulting in stuttering, and in severe cases, even causing the engine to stall. Whether it is a manual transmission or an automatic transmission, there will be a certain frustration in the process of shifting, especially the manual transmission, because the shift operation is completely operated by the owner himself, and the frustration of the manual transmission depends entirely on the driver's operating technique.

The engine needs to be upshifted when the normal speed reaches about 2500 rpm, and downshift is required when it is lower than 1500 rpm. If the rpm is below 1000 rpm, the vehicle may stall. However, due to the different structure of the automatic transmission, the shift operation is controlled by the transmission computer, which will automatically upshift and downshift according to the engine speed.

The frustration depends entirely on the technology of the vehicle's gearbox.

The reasons for the frustration of manual transmission car shift are: 1. The engine speed of the car does not match the wheel speed; 2. The failure of spark plugs, high-pressure packs and other components inside the engine will lead to weak acceleration and even violent shaking and frustration in the process of driving; 3. If the fuel pump is blocked or malfunctioning, the oil pressure will become low, resulting in the fuel being unable to atomize and burn normally. Manual transmission generally refers to the manual transmission, its role is to change the transmission ratio, also known as the gear ratio, is based on the principle of the lever of the torque with the longest radius of the low-speed gear large diameter gear to amplify the engine torque, to assist the vehicle to start moving forward.

The shift frustration is due to the mismatch between the engine speed and the speed of the vehicle at that time when the clutch is lifted, that is, there is a speed difference between the engine speed and the clutch plate speed. In most cases, the engine speed is lower than the clutch plate speed, as long as the clutch is shifted into the new gear, when the clutch is lifted to the semi-linkage, the engine bridge speed is equal to or slightly higher than the clutch plate speed, which can effectively prevent frustration.

The two main ways to solve the frustration of shifting gears: 1When the clutch is lifted to a half-clutch, pause for a moment (this is the passive absorption speed difference); 2.Press down the throttle a little while lifting the clutch and add a little more oil (this is an active way to reduce the speed difference).

The two should be well coordinated, consciously pay attention to practice and practice, and believe that they can solve the problem.

Of course, if you want to keep improving, you also need to pay attention to the timing of lifting the clutch. However, due to the timing of lifting the clutch is related to the gear, speed, speed of shifting, etc., it may be a little difficult for novices or inexperienced people, so don't deliberately pursue perfection when driving.

When the throttle is high-revving (more than 2500 rpm or higher), if you are interested, you can try it out and blind the wheel. Assuming that the 2000 2500 rpm is shifted, the engine speed when the clutch is lifted after changing into a new gear should be lower than the engine speed before the gear shift: 1st gear to 2nd gear, 1000 rpm (the engine tachometer is reduced by 5 small divisions.

and so on); 2nd gear to 3rd gear, 800 rpm (down 4 small squares); 3rd gear to 4th gear, 600 rpm (down 3 small squares); 4th gear shifts to 5th gear, 400 rpm (down 2 small squares).

The reason for the setback: when lifting the clutch, the engine speed does not match the speed of the vehicle at that time, that is, there is a speed difference between the engine speed and the clutch plate speed. In most cases, the engine speed is lower than the clutch plate speed.
