Domestic wheel loaders are transitioning from a low-level, low-quality, low-price, functional type to a high-level, high-quality, mid-price, economical and practical type. In the transition from imitation to independent development, major manufacturers continue to invest in technology, adopt different technical routes, and make technological innovations in key components and systems to get rid of the status quo of similar product designs, without their own characteristics and advantages, from low-level disorderly Stand out from the vicious circle of competition and become the leader in the loader industry.
(1) Large and small wheel loaders are limited by objective conditions and total market demand during the development process. The most competitive medium-duty loaders will be updated faster and faster.
(2) According to the actual situation of each manufacturer, re-design the overall design, optimize various performance indicators, strengthen the strength and rigidity of structural parts, and greatly improve the reliability of the whole machine. (3) Refine the system structure. Such as the vibration reduction of the power system, the optimization of the structure of the heat dissipation system, the optimization of the performance indicators of the working device, the dustproof of each hinge point, and the industrial modeling design.
(4) Use electronic technology and load sensing technology to realize automatic shifting of gearbox and application of hydraulic variable system, improve efficiency, save energy, and reduce loader operating costs.
(5) Improve safety and comfort. The cab is gradually equipped with FOPS & ROPS functions, the environment in the cab will be closer to the direction of the car, and the steering wheel, seat, and various joysticks can be adjusted, so that the operator can work in a position.
(6) Reduce noise and emissions, and strengthen environmental protection indicators. With the enhancement of people's awareness of environmental protection, the work of reducing the noise and emission of loaders has become an urgent task. Many large cities have formulated noise and emission standards for motor vehicles. If construction machinery does not meet the emission standards, it will be restricted to the area. Sale.
(7) Extensive use of new materials, new processes and new technologies, especially the integration of mechanics, electricity and hydraulics, to improve product life and reliability.
(8) Simplify maintenance to the greatest extent, reduce maintenance times and maintenance time as much as possible, increase maintenance space, widely use electronic monitoring and monitoring technology, further improve the fault diagnosis system, and provide drivers with ways to troubleshoot problems.
