Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heavy-load vehicle axles and relates to a vehicle axle with improved bearing capacity. Background Art
[0002] Heavy-duty axles refer to axles used to bear heavy-loaded vehicles. Their main function is to bear and transmit the weight of the vehicle and various forces and moments generated during driving. Heavy-duty axles need to have sufficient strength and rigidity to ensure that the vehicle can drive safely and stably under heavy loads. When the bearing capacity of heavy-duty axles is insufficient, it will bring a series of problems that cannot be ignored. These problems involve vehicle operation, road maintenance, environmental protection and other aspects.
[0003] First, the insufficient bearing capacity of overloaded axles will seriously affect the operation of vehicles. During transportation, if the axles cannot bear the weight they carry, the vehicle will be unstable, shaking, and bumping. This will not only cause driving troubles for the driver, but also reduce the riding comfort of passengers. Moreover, long-term overloaded operation will accelerate the wear and aging of vehicle parts and shorten the service life of the vehicle.
[0004] Secondly, the insufficient bearing capacity of heavy-loaded axles can also cause damage to roads. When heavy-loaded vehicles pass through the road, if the bearing capacity of the axle is insufficient, it will increase the pressure of the wheels on the road surface, accelerating the wear and damage of the road. This will not only reduce the service life of the road, but also increase the cost and difficulty of road maintenance. If the road condition deteriorates, it will further aggravate the damage to the vehicle, forming a vicious circle.
[0005] In summary, insufficient load-bearing capacity of heavy-loaded axles will cause a series of serious problems, affecting the operation of vehicles and the service life of roads. Therefore, when designing and using heavy-loaded vehicles, the load-bearing capacity of the axles must be fully considered, and effective measures must be taken to improve and solve them to ensure the safety, reliability and economy of vehicles and roads. Therefore, there is an urgent need for an axle with improved load-bearing capacity to solve the above problems. Utility Model Content

[0028] The suspension mechanism 120 includes a leaf spring 12a, a holder 12b, a connecting frame 12c, a shock absorbing column 12f and a locking holder 12g. A holder 12b is provided at the middle position of the upper end of the leaf spring 12a.

The position of the leaf spring 12a can be limited by using the holder 12b.
[0031] See also Figure 1-Figure 4 As the first embodiment of the utility model: In order to solve the problem that when a heavy-loaded vehicle passes through a road, if the bearing capacity of the axle is insufficient, the pressure of the wheels on the road surface will increase, accelerating the wear and damage of the road. This will not only reduce the service life of the road, but also increase the cost and difficulty of road maintenance. When a heavy-loaded vehicle is traveling on the road, the vehicle will be bumpy, and the side connecting frame 130 is used to support the suspension mechanism 120 with tension. Since most heavy-loaded vehicles are multi-axis structures, since the two groups of suspension mechanisms 120 are both connected with the outer side of the shaft sleeve 140, a group of suspension mechanisms 120 are provided on both sides of the front and rear of the movable carrier 160, and the movable carrier 160 is respectively connected to the two groups of suspension mechanisms 120 through a group of rotary damping activities.

By using two groups of rotational dampers and the shock absorber column 12f, the roll force generated by the vehicle when the leaf spring 12a is strained can be reduced.
[0033] The internal connection method between the left side of the shock-absorbing column 12f and the lower end of the side connecting frame 130 is the same as the internal connection method between the right side of the shock-absorbing column 12f and the left side of the connecting frame 12c. The shock-absorbing column 12f is a movable mechanism.

When the leaf spring 12a is subjected to force, its left and right ends are subjected to force to squeeze the side connecting frame 130 to move up and down. Since the internal connection method between the left side of the shock-absorbing column 12f and the lower end of the side connecting frame 130 is the same as the internal connection method between the right side of the shock-absorbing column 12f and the left side of the connecting frame 12c, the shock-absorbing column 12f is a movable mechanism, and its side connecting frame 130 can drive the shock-absorbing column 12f to support the deformation force of the leaf spring 12a. At the same time, the seat 12b can limit the movement of the leaf spring 12a, thereby ensuring that the vehicle can improve its bearing capacity.
