Problems solved by technology
There is no high-speed loader with a maximum speed of more than 80km / h in China. Since the loader does not have an inter-axle differential, the traditional four-wheel drive will cause the entire loader to lean forward and backward when driving at high speed, causing the center of gravity of the whole machine to shift. Changes that affect driving safety and, in severe cases, endanger the safety of the driver

The invention relates to an axle device and a construction machine. The axle device includes a first connecting mechanism, a second connecting mechanism, a clutch part (8) and a state switching driving part, wherein the first end of the first connecting mechanism and the first end of the second connecting mechanism are connected with a front axle (2) and a rear axle (4) correspondingly, and the first connecting mechanism is used for being connected with a vehicle power source (5); the position of the clutch part is convertibly arranged at the second end of the first connection mechanism or thesecond connection mechanism; the state switching driving part is used for switching to a first state when a vehicle is running at the first speed, thus the clutch part (8) is in the first position and combined with the second end of the first connecting mechanism and the second end of the second connecting mechanism at the same time; and switching to a second state when the vehicle is running atthe second speed, and thus the clutch part (8) is in the second position to separate the first connecting mechanism from the second connecting mechanism; and the first speed does not exceed the presetoperation safety speed, and the second speed exceeds the preset operation safety speed. According to the structure, the construction machine can be suitable for both high-speed running and low-speedoperation.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, and in particular designs an axle device and engineering machinery. Background technique [0002] Current loaders are generally suitable for low-speed operations. During low-speed operations, in order to increase ground adhesion, four-wheel simultaneous drive is required. There is no high-speed loader with a maximum speed of more than 80km / h in China. Since the loader does not have an inter-axle differential, the traditional four-wheel drive will cause the entire loader to lean forward and backward when driving at high speed, causing the center of gravity of the whole machine to shift. Changes will affect driving safety and will endanger the safety of the driver in severe cases. Therefore, it is necessary to improve the adaptability of the loader to different working conditions. Contents of the invention [0003] Embodiments of the present invention provide an axle device and co...
