As a leading enterprise in the domestic engine field, Weichai Group has been able to improve its competitive advantage and achieve self-development in the aspects of technology upgrading and product layout in recent years. In 2017, the Group achieved a consolidated operating income of 220.8 billion yuan. This eye-catching performance is evidence. Technology is king's proprietary technology to enhance core competitiveness At the Shaanxi Automobile Heavy Truck Mid-Year Marketing Summit in 2018, Weichai Group demonstrated its enthusiasm for the five unique technologies of Shaanxi Power, such as super power, super fuel economy, super lightweight, combined braking and flexible shifting. Chai Group's innovation in technology enhancement and product development will also enhance the overall operational value of users. It is worth mentioning that among the five proprietary technologies, the super-power technology is more subdivided, fully demonstrating the technical advantages of the Weichai engine in every detail. Yang Dong, engineer of Engine Research Institute of Weichai Power Co., Ltd. introduced at the scene that super power technology includes super torque, intelligent idle speed, intelligent transient and Other functions. The super torque function is the ECU automatically adjusts the torque parameter according to the gear position, increasing Torque response speed, a way to control the customer's pursuit of power. By analyzing the difference in driving characteristics under different gear positions, the vehicle power can be reasonably matched. For the intelligent idle speed and intelligent transient function in static and dynamic state, the Chinese truck network reporter learned that the intelligent idle speed adjustment function is a control method for the ECU to automatically adjust the engine speed and enhance the response speed. The comfort and smoothness of the whole vehicle shifting process are improved, and the fuel consumption and working noise of the whole vehicle during the shifting process are reduced. The dynamically designed intelligent transient function is a control method that improves the transient adaptability and fuel economy through the ECU's more precise control of the engine. It can meet customers' needs for transient response and reduce fuel consumption. In addition, the reporter learned that under the premise of guaranteeing the power torque, Weichai and Shaanxi Automobile jointly carried out the calibration and verification of vehicle fuel economy, and developed super fuel-saving technology, which can reduce the fuel consumption of the whole vehicle by 6%. Fuel and intake and exhaust optimization fuel consumption is reduced by 4.6%. At the same time, for the shifting part, Weichai combines the resource advantages of the Group to calibrate the flexible shifting technology, the shifting performance is increased by 40%, the engine is equipped with the transmission shifting booster, and the shifting force is reduced by 30%. In addition, for the safety problem of braking, Weichai's combined braking technology can make the engine braking + retarder combined braking power up to 505kW, which fully meets the 70km/h downhill of the vehicle under the 5% slope of the hilly high speed. A maximum braking power of 477 kW is required. The release of the five proprietary technologies marks that Weichai will continue to focus on technological development and demonstrate the strength of Weichai in research and development, which will lay a solid foundation for a broader market segment. The layout of the country, Liuchai Group, is at the forefront of the industry. On June 28, 2018, the Ministry of Ecology and Environment released the "Limits and Measurement Methods for Pollutant Emissions from Heavy Duty Diesel Vehicles (China's Sixth Phase)" (referred to as the Heavy Vehicle Country Six Standard). The national six standards will be divided into two phases, a and b. The National Sixth Phase will be implemented on July 1, 2019, and on July 1, 2020, on urban vehicles (urban buses, sanitation vehicles, postal vehicles, etc.), and all vehicles will be implemented on July 1, 2021. The national six b phase will be implemented on January 1, 2021 for gas vehicles, and on July 1, 2023, all vehicles will be fully implemented, which indicates that China will begin to gradually enter the sixth era in 2019. In this regard, Weichai Group is full of enthusiasm. In fact, as early as 2017 at the Shanghai Auto Show, Weichai exhibited a new platform diesel engine and clean gas engine that meets the national six emission standards, as well as the WE series plug-in hybrid system assembly and pure electric power system. New energy products. At the Beijing Auto Show in 2018, Weichai exhibited seven engine assemblies with a displacement of 2.3L to 13L and a power output from 128 horsepower to 540 horsepower. In this exhibition engine product show, Weichai displayed the most comprehensive products and all products meet the requirements of the national six regulations. There is no doubt that Weichai is at the forefront of the industry in terms of product layout. We have to say that in the face of the innovative research and development of proprietary technology and the layout of the national six products, Weichai showed the attitude of the industry leader and truly showed its strength.
The Nut Bracket is standardized for the standard Ball Screw assembly provided with finished shaft ends. It is designed to be secured directly on the table with bolts. Since the height is low, it can be mounted on the table only using bolts.
The Lock Nut for the Ball Screws is capable of fastening the screw shaft and the Bearing with a high accuracy. The provided hexagonal socket-head setscrew and the set piece prevent the Lock Nut from loosening and ensure firm fastening. The Lock Nut comes in various types ranging from model M4 to model M40.
The Support Unit comes in six types: models EK, FK, EF, and FF, which are standardized for the standard Ball Screw assembly provided with the finished shaft ends, and models BK and BF, which are standardized for ball screws in general.

The Support Unit on the fixed side contains a JIS Class 5-compliant angular bearing provided with an adjusted preload. The miniature type Support Unit models EK/FK 4, 5, 6 and 8, in particular, incorporate a miniature bearing with a contact angle of 45° developed exclusively for miniature Ball Screws.
This provides stable rotational performance with a high rigidity and an accuracy. The Support Unit on the supported side uses a deep-groove ball bearing.
The internal bearings of the Support Unit models EK, FK and BK contain an appropriate amount of lithium soap-group grease that is sealed with a special seal. Thus, these models are capable of operating over a long period
