Types of Silicone Couplers

Choosing the right silicone coupler means choosing the right product type. Categories include silicone elbows, silicone pressure reducers, straight hoses, hump hoses and coiled hoses.

Silicone elbows contain a molded elbow (bend) that provides great flexibility. Typically, the angle of the bend is 45° or 90°. Dimensions include wall thickness, inner diameter, inner diameter, and length of leg 1 and leg 2.

Silicone reducers or silicone reducers provide a transition between different pipes or pipe sizes. Therefore, one end of the silicone coupler is larger than the other. Dimensions include hose inner diameter, hose outer diameter and length

Straight silicone hoses come in a variety of lengths and can be cut to size by your crew (usually with a razor) or fabricated to order. Silicone hose supports the use of metal clips and may contain fabric reinforcement.

Hump ​​hoses support slight intake adjustments and flex. They can also compensate for small deviations between metal pipes or pipes. Applications include air metering, throttle body assemblies, and inlets and outlets.

Packaging hose provides greater resistance to compression. They are wrapped in polyester mesh, fabric, or an extra layer of silicone.

Silicone performance

Silicone performance:

  1. Silicone products are based on silicon-oxygen (Si-O) bond as the main chain structure, the bond energy of C-C bond is 82.6 kcal/mol, and the bond energy of Si-O bond is in the organic silicon The medium is 121 kcal/mol, so the thermal stability of silicone products is high, and the chemical bonds of the molecules are not broken or decomposed under high temperature (or radiation exposure). Silicone is not only resistant to high temperatures, but also low temperatures, and can be used in a wide temperature range. Whether it is chemical properties or physical and mechanical properties, the change with temperature is very small;
  2. Electrical insulation properties. Silicone products have good electrical insulation properties, and their dielectric loss, withstand voltage, arc resistance, corona resistance, volume resistivity and surface resistivity are among the best in insulating materials, and their electrical properties are affected by temperature and frequency. impact is small. It is a stable electrical insulating material and is widely used in the electronics and electrical industries. In addition to excellent heat resistance, silicone also has excellent water repellency, which is the guarantee of high reliability of electrical equipment in wet conditions;
  3. Physiologically inert, polysiloxanes are among the most inactive compounds known. They are very resistant to biological aging, have no rejection reaction with animals, and have good anticoagulant properties;
  4. Low surface tension and low surface energy, the main chain of silicone is very flexible, and its intermolecular force is much weaker than that of hydrocarbons. Therefore, it has lower viscosity and weaker surface tension than hydrocarbons of the same molecular weight. Small surface energy and strong film-forming ability. This low surface tension and low surface energy are the main reasons for its many applications: hydrophobicity, defoaming, foam stabilization, anti-sticking, lubrication, glazing and other excellent properties.

Principle and Type Analysis of Limited Slip Differential——Type

1. Torsen differential: The so-called Torsen differential is to use worm gear to achieve self-locking, which can work continuously like ordinary differentials, and has no delayed response, and does not interfere with the total torque The adjustment of the output, at this time, there is no loss of torque. Compared with the traction control and body stability control systems, it has a greater advantage in performance and is heavier in weight.

2. Helical gear differential: In fact, the principle is no different from the former, but the helical gear is parallel to the half shaft, and the helical gears are meshed with each other, which means that there will be a certain amount of wear and tear. But it will be slightly lighter in weight.

3. Mechanical differential: It mainly uses two sets of left and right pressure plate groups and clutch plates. The limited slip percentage function can be achieved by the arrangement and combination of clutch plates and pressure plates, and the response speed is very fast, but the difference between the differential oil The fluidity is relatively poor and the heat dissipation performance is not very good, so the durability is not very good.

4. Eaton differential: In fact, this differential is also a mechanical differential, but it is slightly simpler in structure than a mechanical differential. A flyweight is set in the differential housing. When the speed difference reaches When a certain value is reached, the flyweight will be locked, and the wheels on both sides will be connected linearly, so as to achieve the purpose of getting out of trouble.

Features of friction limited slip differential

The friction differential improves the locking coefficient of the differential by increasing the internal friction during differential rotation. There are roughly three practical structures: internal friction limited-slip differential, slider cam limited-slip differential and a worm gear limited-slip differential.

The internal friction differential increases the resistance torque of differential rotation by adding friction plates between the back of the axle shaft and the differential housing. It can be divided into two categories with spring preload and no spring preload: the differential resistance torque of the differential with spring preload is basically constant, which has nothing to do with the output torque of the drive axle, so the vehicle is under light load. When turning down, the traction force generated by the outer wheels is negative, which not only reduces the power of the vehicle, but also increases the loss of tires; the non-preloaded differential needs to stack multiple friction plates behind the half shafts to achieve the required locking compact coefficient, and its structure is not compact. This type of differential has special requirements for lubricating oil, and the different requirements for oil of hyperbolic gears and friction plates should be taken into account when selecting. Because its work is relatively stable and the technology is relatively mature, it is widely used in off-road vehicles, luxury cars and construction machinery abroad.

The slider cam type limited slip differential has a wide range of applications, and the main components include the differential case, the slider, and the inner and outer cams. According to the different installation direction of the slider, it can be divided into radial slider type and axial slider type; according to the different number of slider installation rows, it can be divided into single row slider type and double row slider type. When the adhesion coefficients of the left and right wheels and the road surface are different, and the ratio of the two does not exceed the locking coefficient, the slider cam differential can ensure that the wheels with poor adhesion coefficients do not slip. When the adhesion of the left and right wheels to the road surface is good, the left and right wheels can roll normally according to the motion requirements and maintain good steering performance. However, the structure of this type of differential is relatively complex, and the requirements for molding, materials, chemical treatment, heat treatment, etc. are relatively high, so the cost is also relatively high. 

Worm gear limited-slip differentials are mainly used in trucks, off-road vehicles and road tractors, and can cope with various complex road conditions. Currently, the most widely used is the Torsen differential. The Torsen differential was developed by Gleason Company in the United States. [3] It makes full use of the self-locking and high-friction characteristics of the worm gear, so that the locking coefficient of the differential has been greatly improved. Torsen differentials have reliable performance and compact structure. They can not only automatically prevent slippage, but also automatically adjust the locking coefficient according to the different turning radius and road driving conditions. However, when the torque difference is large, this type of differential will automatically lock, which affects the normal differential function. Therefore, this type of differential is generally not used as a wheel on the steering drive axle. Differential used.

Frition Plate Limited Slip Differential(LSD) explained

Frition Plate Limited Slip Differential(LSD) essentially consists of an ordinary bevel gear differential combined with friction plates which can (partially) engage the side gears to the differential cage. The larger the torque, the greater the locking effect.

The friction plates usually have a spline connection with the side gears. The outer plates are usually connected with a sliding connection to the differential cage. The outer plates will always have the same speed as the differential cage, and the friction plates have the same speed as the side gears and drive shafts.
