Description

Technical Field

[0001] The utility model relates to the field of engineering vehicles, in particular to an integrated lubricating oil circuit for a trackless man-carrying vehicle for mining. Background Art

[0002] In the mining environment, trackless vehicles are important means of transportation, and their stability and durability are directly related to production efficiency and operational safety. However, the lubrication system of traditional trackless vehicles often has problems such as complex design, difficult maintenance, and uneven lubrication effect, especially in the lubrication of key components such as steering axles and leaf springs. These problems are particularly prominent.

[0003] The traditional trackless vehicles have scattered lubrication points, which need to be lubricated manually one by one, which is not only inefficient but also easy to miss, resulting in accelerated wear of some parts due to insufficient lubrication. Due to the scattered lubrication points and the lack of a unified lubrication system, it is difficult to ensure the consistency of the lubrication effect of each component, which in turn affects the performance and life of the vehicle, and needs to be improved. Utility Model Content

[0004] The utility model aims to provide an integrated lubricating oil circuit for a mining trackless vehicle with small occupied space and convenient lubricating oil filling management in view of the above problems.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses an integrated lubricating oil circuit for a mining trackless vehicle, whose structural features are: it includes a front oil filling seat installed on the front side of the frame, a plurality of lubricating oil pipes are connected to the front oil filling seat, and the other end of the lubricating oil pipe is connected to the lubrication point of the steering axle and the front leaf spring; a rear oil filling seat is installed on the rear side of the frame, a plurality of lubricating oil pipes are connected to the rear oil filling seat, and the other end of the lubricating oil pipe is connected to the lubrication point of the rear leaf spring.

[0006] Through integrated design, multiple lubrication points are centrally controlled, reducing the complexity and space occupied by the lubrication system. Lubricating oil can be quickly and accurately delivered to each lubrication point, improving lubrication efficiency, ensuring full lubrication of each component, and reducing the risk of component failure and safety accidents caused by poor lubrication. Centralized control and unified lubrication of lubrication points can not only improve lubrication efficiency, but also reduce maintenance costs and enhance the performance and safety of the vehicle. Centralized supply and distribution of lubricating oil is achieved, simplifying the structure of the lubrication system and facilitating maintenance and management. At the same time, this design reduces the complexity of the lubricating oil pipeline and improves the reliability and stability of the system.

[0007] Preferably, a kingpin is installed on the steering axle, a steering knuckle is installed on the wheel hub, the steering knuckle and the kingpin are hinged, and the lubrication points of the steering axle include the hinge between the steering knuckle and the kingpin.

[0008] The steering axle is equipped with a steering tie rod, which is hinged to the steering knuckle through a tie rod pin. The lubrication points of the steering axle also include the hinge of the steering tie rod and the steering knuckle. The hinge of the steering knuckle and the kingpin, as well as the hinge of the steering tie rod and the steering knuckle are used as lubrication points to ensure the flexible operation and wear resistance of these key components. Effective lubrication can reduce friction, reduce wear, extend the service life of components, and improve the handling and safety of the vehicle.

[0009] The front leaf spring is provided with ears at both ends, bushings are installed in the ears, a front bracket is installed on the frame, the bushings in the ears at the front ends of the front leaf springs are hinged on the front bracket, and the lubrication points of the front leaf spring include the hinges between the bushings and the front bracket.

[0010] The frame is equipped with a lifting eye bracket, on which a lifting eye is hinged. The bushing in the rear end ear of the front leaf spring is hinged on the lifting eye. The lubrication points of the front leaf spring also include the hinge between the lifting eye bracket and the lifting eye, and the hinge between the bushing and the lifting eye. The lubrication points of the front leaf spring cover the hinge between the bushing and the front bracket, as well as the hinge between the lifting eye bracket and the lifting eye, and the hinge between the bushing and the lifting eye. Lubrication of these parts can reduce wear and noise caused by direct contact between metals, and improve the service life of the leaf spring and the driving stability of the vehicle.

[0011] The lubrication points on the rear leaf springs are the same as the front leaf springs, ensuring balanced lubrication between the front and rear of the vehicle, helping to maintain the overall performance and stability of the vehicle.

[0012] There are two front oil filling seats, which correspond to the left and right front leaf springs and the lubrication points on the left and right sides of the steering axle respectively.

[0013] There are multiple oil filling holes on the front and rear oil filling seats, and the lubricating oil pipe is connected to the rear end of the oil filling hole. The two front oil filling seats are respectively corresponding to the left and right front leaf springs and the left and right lubrication points of the steering axle, which realizes the precise distribution of lubricating oil and avoids the uneven lubrication problem caused by a single oil filling seat. At the same time, this arrangement also improves the flexibility and adaptability of the lubrication system.

[0014] The front and rear oil filling seats are both equipped with oil plugs for sealing the oil filling holes. The oil filling holes are convenient for filling lubricating oil, and the design of the oil plugs can effectively prevent lubricating oil leakage and contamination when not in use, thereby improving the system's sealing and ease of maintenance.

[0015] A bumper is installed on the front side of the frame, and an avoidance hole is opened on the bumper. The front oil filling seat is located behind the avoidance hole. The front oil filling seat is hidden behind the bumper and protected by the bumper, which not only ensures the normal operation of the lubrication system, but also improves the overall safety and practicality of the vehicle.

[0016] A grease nipple is installed on the lubrication point, and one end connected to the lubrication point is installed on the grease nipple. For example, a grease nipple is installed on the tie rod pin and the king pin, and the lubricating oil enters the tie rod pin and the king pin through the grease nipple.

[0017] In summary, the beneficial effects of the utility model are as follows: through integrated design, multiple lubrication points are centrally controlled, reducing the complexity and space occupied by the lubrication system. Lubricating oil can be quickly and accurately delivered to each lubrication point, improving lubrication efficiency, ensuring full lubrication of each component, and reducing the risk of component failure and safety accidents caused by poor lubrication. Centralized control and unified lubrication of lubrication points can not only improve lubrication efficiency, but also reduce maintenance costs and enhance the performance and safety of the entire vehicle. Centralized supply and distribution of lubricating oil is achieved, which simplifies the structure of the lubrication system and facilitates maintenance and management. At the same time, this design reduces the complexity of the lubricating oil pipeline and improves the reliability and stability of the system. BRIEF DESCRIPTION OF THE DRAWINGS
