Problems solved by technology

However, the hardness of the carbon fiber cloth after drying is relatively high, and the direct flattening will cause the carbon fiber to break
The bonding is to press the base of the synchronizer gear ring and the carbon fiber cloth with a die, but the surface of the base of the synchronizer ring is tapered, and the flattened carbon fiber cloth cannot match the base of the synchronizer ring. one-shot carbon fiber breakage
Leading to poor friction stability and low service life of the synchronizer ring in use
[0006] Chinese invention patent CN200410013150.2 discloses a carbon fiber friction material and usage of the steel synchronizer gear ring for automobiles. This patent studies the wear-resistant material of the steel synchronizer. The friction performance of the alloy copper is not as good as that of alloy copper. The method of spraying molybdenum on the conical surface of the synchronizer ring is used to improve its friction performance. Since the price of molybdenum is still high, the economy of the finished product is poor.
At the same time, there is also the problem of carbon fiber fracture caused by the preparation process

Embodiment 1

[0063] Embodiment 1, the preparation method of synchronous ring wear-resistant material comprises the following steps:

[0064] Step 1. Mix the raw materials in the weight ratio of the components in Example 1 in Table 1 except the basalt fiber mat, and stir the raw materials evenly to make an infusion.

[0065] Step 2. Perform plasma treatment on the basalt fiber felt, and the plasma reaction time is 2-3 minutes.

[0066] Step 3. Cut the basalt fiber felt according to the size matching the synchronous ring, such as figure 1 shown. Brush the immersion solution on the basalt fiber felt for impregnation, and put the impregnated basalt fiber felt into a vacuum dryer to dry.

[0067] Step 4. Bond both ends of the dried basalt fiber felt, and then put it on a conical mold for pressing, so that the taper of the basalt fiber felt and the surface of the synchronous ring base is the same, as shown in figure 2 shown.

[0068] Step 5. Bond a layer of basalt fiber felt on the surface ...

Abstract

The invention belongs to the field of automobile transmissions and particularly relates to a wear resistant material of a synchronous ring. The wear resistant material comprises the following ingredients in parts by weight: 23-35 parts of basalt fibrofelt, 8-20 parts of high-temperature resistance resin, 2-7 parts of molybdenum disulfide, 12-25 parts of graphite powder, 18-30 parts of silicon carbide powder, 3-8 parts of iron powder, 1-4 parts of brass powder and 12-20 parts of precipitated barium sulphate. The ingredients and a proportion of the wear resistant material of the synchronous ring are changed; a preparation technology of the wear resistant material is optimized, so that the bonding strength among the ingredients of the prepared wear resistant material of the synchronous ring is high; and a finished product is good in wear resistance and long in life in actual use.

Description

technical field [0001] The invention belongs to the field of automobile transmission devices, and in particular relates to a synchronous ring wear-resistant material and a preparation method thereof. Background technique [0002] The synchronization ring is an important part of the synchronizer, it can effectively reduce the vibration, impact and noise during the shifting process of the car, thereby improving the stability of the car's handling and the safety of driving. When the inner tapered surface of the synchronous ring contacts with the outer tapered surface of the gear ring gear to be joined, the speed of the gear rapidly decreases or rises to the same speed as the synchronous ring under the action of friction torque, 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 push of the active force, the coupling sleeve engages with the synchr...
