The windshield wiper transmission is an integral component of your vehicle`s windshield wiper system. It is a mechanical device made up of multiple linkages that connect the Wiper Motor to the two wiper arms, transferring the power generated from the rotational movement of the motor when it is activated by the wiper controls into the sweeping back and forth motion of the windshield wiper arms which the blades that clean the windshield are attached to. The wiper transmission helps the wiper motor and arms work together without having to hit each other. The multiple sections of linkage are joined and held together by rivets, while bushings are mounted to the Wiper Linkage arms and act similarly to bearings. Together, they make it possible for the different sections of the wiper linkage assembly to rotate and pivot.
On most vehicles, the wiper linkage assembly is located under the cowl at the base of the windshield and hidden out of view. This protects the mechanism from being exposed to outside elements and allows for it to operate quietly when being used.
Windshield wiper transmissions are the most common failed parts of the wiper system and can require replacement for multiple reasons. A windshield wiper linkage assembly will make an annoying clunking or squeaking sound when they wear out from prolonged use over time. Turning on frozen wiper blades without properly loosening them from an icy windshield during the cold winter season is a notorious and common cause of damage to wiper systems; this forces the wiper motor to put excess stress on the wiper linkages and arms. This stress can cause plastic connectors to break, pivot points to elongate, and knurled wiper studs to round off. Heavy snow and ice can also force the wiper motor to put excess stress on the linkages and wiper arms, as can large amounts of dirt, causing a similar outcome.
A broken or damaged windshield wiper linkage assembly can cause the wipers to not work or work incompletely, which can be quite hazardous for you and other drivers around you. Therefore, if your wiper transmission has failed, obtaining a replacement and installing it quickly is highly recommended.

In recent years, the market demand of the domestic machine tool industry has gradually shifted to mid-to-high-end machine tools. With the slowdown in total market growth, the market share of high-precision, intelligent CNC machine tools has increased, and the proportion of CNC machine tools in total machine tool consumption has risen to more than 60%. CNC machine tools are developing in the direction of high speed, precision, intelligence and green.
The Chinese machine tool industry has achieved sustained ultra-high speed development in the past few years. Until the first half of 2011, demand was still very strong. However, from the second half of last year, the demand growth slowed significantly, new orders fell sharply, and the economic benefits Gradually, the profit rate continues to decline.
During the 12th Five-Year Plan period, the state implemented a proactive fiscal policy and a prudent monetary policy. With the advancement of science and technology, product upgrades, and the continuous advancement of national key projects and local investment projects, the demand for machine tool products in various sectors of the national economy will further increase. To increase, the demand for high-level machine tools will be more urgently needed for national defense modernization, market demand will develop to a higher level, and a new round of market competition will also become more intense.
Due to the sluggish industry climate, the downstream manufacturers' demand for machine tools has declined, so China's machine tool industry has been in a sluggish state. Upgrade and transformation have become key words for the industry in recent years, and economical CNC machine tools have become one of the focuses of the revitalization of equipment manufacturing.
