How does a synchronizer work?

The working principle of the synchronizer is to make the clutch plate also synchronize with the flywheel, the speed must be the same to smoothly engage the gear, if the shift is slow, the speed falls to idle, it is impossible to hang in, and the downshift should be in the neutral position (while keeping the clutch raised) to the accelerator to reduce the speed difference of the gear.

However, this operation is more complex and difficult to grasp accurately. Hence the designers created"Synchronizer", through the synchronizer, the gears to be engaged reach a consistent speed and engage smoothly.

Classification structure of synchronizers:

The synchronizer has the form of atmospheric pressure type, inertial type, self-increasing type, etc., and the inertial synchronizer is widely used, which is mainly composed of joint sleeve, synchronizing lock ring, etc., and it is characterized by relying on friction to achieve synchronization.

In this type of synchronizer, the axial direction of the butt sleeve.

The resistance is caused by the pressure of the spring, so its magnitude is limited. If the driver exerts more force, it is possible that before the synchronization is reached, the coupling sleeve overcomes the spring pressure, presses down the positioning pin and contacts with the engagement ring gear of gear 2, and the impact between the teeth will still be generated at this time.

Some heavy trucks, in order to improve the gear shift process, use friction plate type atmospheric pressure synchronizer. The difference between it and the above-mentioned atmospheric synchronizer is that it makes full use of the axial space to increase the number of friction plates to increase the frictional torque required during synchronization.

The working principle is as follows: 1. (1) The input shaft and output shaft of the transmission rotate at different speeds, and when changing gears, the two gears rotate at different speeds, and if they are not "synchronized" and forcibly meshed, the two gears will inevitably collide with each other, so the gears will be damaged. (2) The shift of the old type of transmission should adopt the method of "two-foot clutch", when changing gears, step on the clutch once, pull the gear out to neutral, let go of the clutch, stay in the neutral position for a while, and then step on the clutch again to put the gear into another gear.

3) But this operation is more complicated and troublesome. Therefore, modern gearboxes are designed with a "synchronizer", through which the gears to be engaged reach the same speed and smoothly engage and shift. 2. The synchronizer has atmospheric pressure type and inertial type.

At present, all synchronous transmissions use inertial synchronizers, which are characterized by friction to achieve synchronization. 3. There are chamfers (locking angles) on the gear rings of the joint sleeve, synchronous rings and gears to be engaged. The inner cone of the synchronizer ring is in contact with the outer cone of the gear ring to be engaged, resulting in friction.

Cone friction allows the sleeve to be meshed to quickly synchronize with the ring gear, while at the same time creating a lock-up effect that prevents the gear from engaging before synchronizing. 4. When the inner cone surface of the synchronous ring is in contact with the outer cone surface of the gear ring to be engaged, under the action of friction torque, the gear speed is rapidly reduced (or increased) to be equal to the speed of the synchronous ring, and the two rotate synchronously, and the speed of the gear relative to the synchronous ring is zero, so the moment of inertia also disappears at the same time, at this time, under the impetus of the gear shift lever force, the joint sleeve is unhindered and engages with the synchronous ring gear ring, and further engages with the gear ring of the gear to be engaged, and completes the process of shifting.

Through the synchronizer, the gears to be meshed reach the same speed and mesh smoothly, and the common structure of the synchronizer is in the form of gear sleeves, sliders, and copper rings.

Shift gears from older transmissions"Clutch with both feet"way, upshift stay in the neutral position for a while (but the clutch needs to be raised, the purpose is to make the clutch plate and the flywheel also synchronize, the speed must be the same to smoothly engage the gear, if the shift is slow, the speed falls to idle, it can not be hooked in), downshift should be in the neutral position (while keeping the clutch raised) throttle to reduce the speed difference of the gear. However, this operation is more complex and difficult to grasp accurately. So the designers created the synchronizer.

The role of the synchronizer is:

Quickly synchronizes the adapter sleeve with the ring gear to be engaged and prevents it from engaging before synchronizing. There are three types of synchronizers: atmospheric type, automatic force increase type and inertial type. Inertial synchronizers are commonly used in contemporary automobiles. An inertial synchronizer consists of a synchronization device, a locking device, and a engagement device.

Types of synchronizers:

The types of synchronizers include atmospheric pressure type, inertial type, self-increasing type and other forms. At present, inertial synchronizers are widely used. It is mainly composed of splicing sleeves, synchlock rings, etc., and it is characterized by relying on friction to achieve synchronization.

Introduction to the specific classification of synchronizers

1. The inertial synchronizer relies on friction to achieve synchronization. However, it can be structurally guaranteed that the joint sleeve and the spline ring to be bonded cannot be in contact until synchronization is reached, so as to avoid inter-tooth impact and noise. Inertial synchronizers are widely used in transmissions for cars and light and medium-duty trucks.

There are two commonly used structural forms: locking ring inertial synchronizer and locking pin inertial synchronizer.

2. Locking ring inertial synchronizer: Locking ring synchronizer has small size, compact structure and small friction torque, and is mostly used in cars and light vehicles.

3. Lock-pin inertial synchronizer: large and medium-sized trucks generally use lock-pin inertial synchronizer.

A synchronizer is a device that synchronizes gears that engage each other during gear shifting. During the gear shift, the circumferential velocity of the engaged ring gear of the pair of gears to be meshed should be equal (i.e., synchronized) in order to smoothly engage the upper gear. Otherwise, there will be impact and noise between the two gear rings, which will affect the life of the gears.

The function of the synchronizer is to quickly synchronize the joint sleeve and the ring gear to be meshed when shifting gears, and then enter the meshing to achieve no impact and no noise shifting.

At present, the friction inertial synchronizer is mainly composed of three parts: a synchronization device, a locking device and a joint device.

Due to the different locking devices, there are two types: locking ring type and locking pin type.

Automobile synchronizers, generally inertial synchronizers, common structures in the form of tooth sleeves, sliders, copper rings. The function of the synchronizer is to reduce the speed difference of the corresponding working gears inside the transmission when shifting gears, realize the synchronization of speed, and then complete the gear operation. It is very professional and difficult to express clearly in short words.

The synchronizer is mainly composed of a locking ring, a spline hub, a slider, a joint gear ring and a bonding sleeve. The function of the synchronizer is to use the combination sleeve lock ring to engage the gear ring with the gear of the required gear shift when changing gears, so as to achieve synchronization, so as to realize gear shifting.

I don't know what kind of occasion the synchronizer is used for.

The synchronizer I know is used in a three-phase AC parallel device, which is mainly used to detect phase synchronization and then give synchronization commands. There are static and dynamic synchronizations.

There is a very important device inside the structure of a manual transmission, and that is the "synchronizer". The role of the synchronizer is very obvious, that is, when shifting gears, because the gear speed at the power take-off end is faster than the gear that is about to be shifted into this gear, to solve the inconsistency between the engine speed and the gearbox speed in the shift operation, he can effectively avoid hanging up the gear, eliminate the gear sound when shifting, etc., if there is no synchronizer, a slow-rotating gear is forcibly stuffed into a high-speed rotating gear, and the phenomenon of toothing will definitely occur.

The Role of Automotive Synchronizers – An Introduction.

The function of the automobile synchronizer is to quickly synchronize the coupling sleeve with the ring gear to be meshed, so as to shorten the shift time. Prevent the impact between the joint sleeve and the gear ring to be meshed before synchronization and produce the impact between the joint teeth, so that the gear shift is smoother and the noise of the gear shift gear is reduced. The synchronizer is composed of three parts: the same step device (including the pushing part and the friction part), the locking device and the joint device.

There are many kinds of synchronizers, such as atmospheric pressure type, inertial type, and self-increasing force type. At present, almost all synchronizers use friction inertial synchronous devices, which are divided into locking ring inertial synchronizers and locking pin inertial synchronizers according to different locking devices.

The role of the car synchronizer – type.

At present, in most cars and large trucks, in addition to the reverse gear and the first gear, other gears are equipped with synchronizers, and the requirements for the synchronizer are large torque capacity, stable performance, durability, and good economy.

In general, most cars are equipped with inertial synchronizers. The inertial synchronizer can ensure synchronous meshing and gear shifting, and the performance is stable and reliable. It can be divided into two main categories:

Inertial lock-up synchronizers and inertial booster synchronizers. The most widely used are locking ring, locking pin and other inertial locking synchronizers.

The main function of the automobile synchronizer is to make the car more stable driving, simply put, the synchronizer is a friction plate arranged on the combination sleeve and gear set, but the difference with the general friction plate is that the friction surface of the friction plate is tapered. Its direct effect is to carry out friction in advance before the vertical teeth of the straight teeth and the vertical teeth of the disc come into contact with each other, so as to transfer the energy of the side with a larger speed to the side with a smaller speed, so as to ensure that the speed of the side with the smaller speed increases, so that it is synchronized with the speed of the side with the larger speed.

How the synchronizer worksThe working principle of the synchronizer is to achieve a consistent speed of the gears to be meshed through the action of friction, so that they mesh smoothly.

A brief introduction to the synchronizer only hall moldThe synchronizer is a common mechanical component in automobiles, and its purpose is to achieve the same speed of the volvul gear when changing gears. The structure of the synchronizer is divided into three main types, namely atmospheric pressure type, inertial type, self-increasing type, and the products formed by different structures are different, so it can be divided into atmospheric pressure synchronizer, habitual slow synchronizer and self-increasing force synchronizer, among which the inertial synchronizer is currently widely used.
