Two-stage reducer.

It is a rotating gear and a rotating gear (often referred to as an empty set gear). The detachable gears are connected to the gearbox.

axis and rotate clockwise. The smoothing tool is close to the right side of the computer, and the engagement point rotates downwards to align with the direction the wheel is heading. Since the diameter of the rotary gear decreases, the diameter of the rotating tool increases, so the deceleration function is obtained.

The secondary reducer has an intermediate transition tool, the left side of the steering spine is meshed with the tool that loosens the intermediate tool, the release tool is coaxial with a small diameter spur gear, the spindle gear is meshed with the driven tool, the intermediate gear rotates backward, the pushed gear rotates forward, and there is a two-stage deceleration process in the center.

Due to the increase in the volume of the axles, the two-stage deceleration was mainly used for vehicles with low engine power in the past, but is now mainly used for low-speed and high-torque construction machinery.

According to the characteristics of the engine and the operating conditions of the vehicle, when the final reducer is required to have a large main drive ratio.

, the main single-stage reducer, consisting of a pair of bevel gears, is oversized due to the excessive size of the gears, which does not guarantee sufficient minimum soil clearance. Now you need to use two sets of gears to achieve deceleration.

According to the characteristics of the engine and the operating conditions of the vehicle, when the final reducer is required to have a large main drive ratio, the main single-stage reducer composed of a pair of bevel gears is too large due to the excessive gear size, which cannot ensure sufficient minimum soil clearance. Now you need to use two sets of gears to achieve deceleration.

According to the different two-stage reducer, the main two-stage reducer can be divided into different structural schemes: the most common is the first stage of helical gear transmission.

The second stage is cylindrical gear transmission; In addition, there are first-stage gate gear transmission, two-stage planetary gear transmission or first-stage planetary gear transmission, two-stage gearbox transmission or first-stage cylindrical gear transmission, two-stage downhill gear transmission, etc.

<> According to the gearbox torque structure of the reducer, the gear transmission of the main reducer mainly includes spiral screw transmission, hyperbolic gearbox transmission, cylindrical gear transmission (can also be divided into fixed shaft transmission and gear rotary shaft transmission, that is, planetary gear transmission) Advantages: It can achieve a large transmission ratio, the two-stage reducer has a compact structure, the transmission is relatively stable, the input and output ends of the reducer can be arranged vertically to each other, and the disadvantages of a wide range of applications are: low efficiency and heat.

The steam turbine is a non-ferrous metal with a complex structure.

The reducer that only appears in heavy vehicles or medium-duty vehicles is done to better control the speed, avoid problems and protect safety.

The two-stage reducer has one more intermediate transition gear than the ordinary reducer, the left side of the driving vertebral gear is partially meshed with the bevel tooth of the intermediate gear, and the bevel gear has a spur gear of small diameter on the same axis, and the spur gear is meshed with the driven gear, so that the intermediate gear turns backward and the driven gear rotates forward.

It is a kind of part, this kind of part can slow down the car, can make the car brake suddenly to get cushioned, is a part of the car parts.

It can make the car avoid bumps, and such parts are the two-stage reducer, and the two-stage reducer can end the speed of the car.

In automobile reducer, bipolar reducer means more horsepower, which can quickly decelerate at high speeds.

1) It has a two-gear transmission ratio.

The final drive is called a two-speed final drive.

2) The wide-rolling two-stage final reducer is composed of two gear pairs, which are slowed down twice, and the transmission ratio of the final reducer is only one, and it is fixed. However, there are two transmission ratios output by the double-hare Li speed final reducer, and the transmission ratio of the main reducer is changed by the driver's control according to the driving situation of the car.

3) The purpose of adopting a two-speed final reducer is to improve the power and economy of the transport vehicle.

Summary. Hello, the speeder plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery. Reducers can be divided into two categories: general reducers and special reducers according to their uses.

No matter what type it is, the reducer looks at the number of stages of deceleration to see his transmission shaft, and 2 is a level of deceleration. 3 is a two-stage deceleration, and so on.

How to divide the several stages of deceleration of the reducer and how to distinguish them.

When you encounter obstacles and congestion in normal high-speed driving and need to slow down: first release the accelerator pedal, step on the brake to slow down, reduce the speed to a suitable speed according to the actual road conditions, press the clutch pedal, dial the gear lever to the gear that matches the speed, and continue driving; When going down a long or steep slope: according to the size and length of the ramp, decelerate and downshift in advance, use the engine braking, use two or one gear downhill, if the speed is still fast, you can step on the brakes intermittently, and it is strictly forbidden to slide in neutral gear or step on the clutch and brake.

First of all, we have to figure out a problem, gear and speed is not a one-to-one relationship, several gears must correspond to the speed of tens of km h, which involves the problem of engine speed, that is to say, the speed corresponding to a gear is actually a speed range, which is also the basis for us to be able to shift gears, because some cars 2nd gear and 3rd gear speed range overlap is not large, and the throttle is needed to reconcile. And at this time, the car in front of us has already started to go, and we don't need to stop. Instead, we need to refuel and gear up to keep up with the speed of traffic.

You can press the clutch and release the throttle while keeping your foot on the brake pedal and ready to brake at any time. Stepping on the clutch is mainly about the fear that the car will stall. After that, if it is blocked, you need to put the car in neutral gear to save the fatigue of stepping on the clutch with your left foot.

Especially for friends who are not familiar with manual transmission, just remember this, because the situation is urgent, and when you do other operations, it will affect the reaction time, and stepping on the clutch or hanging neutral gear at high speed will lose the effect of engine braking, and the braking distance will become longer.

The engine is the power system of the car, which transmits power to the gearbox through the clutch, and then the gearbox transmits the power to the driving wheels to make the car drive. If the speed is fast, you need to brake sharply, step on the brakes, do not step on the clutch, the purpose of not stepping on the clutch is to use the braking force of the car to drag the engine to run, that is, "engine braking". At this time, you can force a low gear or play a direction to dodge, etc., if the ignition is turned off, you can't do anything.

When the transmission of the final reducer is relatively large, in order to ensure that the car has sufficient ground clearance, it is necessary to use a two-stage final reducer. The bipolar reducer has an additional intermediate transition gear, so that the intermediate gear turns backward and the driven gear turns forward.

The single-stage reduction axle is a conventional drive axle, which has a set of bevel cone gear sets (commonly known as pot angle teeth) in the middle of the gear pack (commonly known as tooth pack) to reduce and increase torsion. Due to the large basin teeth, the gear pack shell in the middle of the axle must also be enlarged, and the volume of the single-stage axle main reducer is larger, resulting in the decline of the axle passing capacity, but the mechanical efficiency is high (the larger the load, the larger the gear pack), the axle housing is very bulky, and the ground clearance is small. The two-stage reduction axle is generally a wheel side reduction axle, and its structure is that there are small diameter external gears at the end of the half shaft, and there is a group of planetary gears (generally 5) around it, and there are teeth in the hub to surround this group of planetary gears to achieve the purpose of deceleration drive.

Its advantage is that the deceleration performance is better (the driving force is increased), and the volume of the main reducer with wheel side deceleration can be reduced, so the passability is improved, but there is an additional one-stage transmission, and the mechanical efficiency is reduced. The passing performance of the vehicle is greatly improved, and the disadvantage is the increased cost and maintenance expenses.

The number of gears involved in the reduction transmission is different, which can be divided into single-stage final reducer and two-stage final reducer. Some medium and heavy-duty vehicles that require large gear ratios use two-stage final drives. Its main purpose is to provide greater half-shaft torque at the same propeller shaft speed, i.e. to enhance the function of deceleration and torque increase, which is suitable for heavy-duty vehicles.
