Description

Technical Field

[0001] This utility model relates to the field of steering gear technology for engineering vehicles, and in particular to an angle-locking steering gear adjustment bracket for engineering vehicles. Background Technology

[0002] Engineering vehicles refer to special vehicles specifically designed for the engineering construction field. They have specific functions and structures, serving various engineering scenarios such as roads, bridges, buildings, and water conservancy. They are diverse in type, covering excavators, loaders, bulldozers, road rollers, cranes, and concrete mixer trucks. These vehicles possess powerful performance, durable mechanical structures, and professional operating devices, enabling them to efficiently complete various complex tasks in engineering construction. They are indispensable and important equipment in the engineering construction process, playing a key role in improving engineering efficiency and ensuring project quality.

[0003] The steering gear of an engineering vehicle is the core component of its steering system. It primarily controls the vehicle's direction, ensuring that the vehicle steers or maintains a straight line according to the driver's input. Through mechanical or hydraulic transmission, it transmits the driver's force from the steering wheel to the steering wheels, enabling precise adjustment of the steering angle. Engineering vehicle steering gears are characterized by robust construction and high load-bearing capacity to meet the demands of engineering vehicles operating in complex road conditions and harsh environments with heavy loads. Their performance directly affects the vehicle's handling, safety, and operational efficiency. For example, in construction and mining transportation scenarios, a reliable steering gear ensures flexible vehicle steering, preventing accidents caused by steering failure, and ensuring the smooth operation of the engineering vehicle. For the smooth operation of the mission, engineering vehicles often operate in harsh environments, such as construction sites with heavy dust and mud. If the waterproof and dustproof performance of the adjustment frame is not good, dust and mud can easily enter the adjustment mechanism, accelerating the wear of parts, affecting the locking effect and adjustment flexibility, and reducing the reliability of the adjustment frame. In the existing technology, an integrated electric grease pump is used to periodically inject waterproof grease into the key parts of the adjustment mechanism through a timer or sensor trigger, forming an oil film to block contaminants and flush away residual dust inside. However, for engineering vehicles equipped with a height-adjustable cab, the fixed steering wheel angle will cause the operating plane to mismatch with the driver's position after the cab height changes, affecting the accuracy of operation. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an angle-locking steering gear adjustment bracket for engineering vehicles, which aims to improve the problem in the prior art that when the height of the cab changes, the fixed steering wheel angle will cause the operating plane to mismatch with the driver's position, affecting the accuracy of operation.
