Description

Technical Field

[0001] This utility model relates to the field of loader technology, and in particular to a chassis and a loader. Background Technology

[0002] In hydraulic transmission systems, hydraulic transmission relies on the kinetic energy of the working medium to transmit power. Common hydraulic transmission methods include hydraulic couplings and hydraulic torque converters. Unlike hydraulic transmission, hydrostatic transmission relies on the pressure energy of the working medium to transmit power, resulting in high transmission efficiency. Furthermore, hydrostatic transmission decouples traction force from engine speed, meaning traction force is not strongly correlated with engine speed. A hydrostatic loader can output maximum traction force at an engine speed of 1200 rpm. In contrast, hydraulic transmission requires maximum throttle to obtain sufficient traction force, causing the engine to operate in a high-fuel-consumption range. Hydrostatic transmission, however, only requires a light touch on the accelerator to achieve maximum traction force, allowing the engine to operate in its high-efficiency range throughout the digging process, resulting in good fuel economy. Therefore, hydrostatic transmission has become a new transmission form for construction machinery with promising application prospects. To meet international market demands, there is a need to develop small hydrostatic transmission loaders. However, the existing rear frame of small hydraulic transmission loaders cannot accommodate the layout of various systems in a hydrostatic transmission system, nor can it meet the space constraints of small loaders.

[0003] Therefore, a chassis and loader are needed to solve the above problems. Utility Model Content

The engine assembly mounting part 50 and the radiator mounting part are disposed on the fixing frame 40 and are spaced apart along a first direction, wherein the first direction is perpendicular to the extension direction of the first side plate 20. Specifically, in this embodiment, the frame 1 has an engine assembly mounting part 50 and a radiator mounting part spaced apart along a first direction on its mounting bracket 40, which are used to install the engine assembly and the radiator 5 respectively. This makes the engine assembly and the radiator 5 spaced apart along the first direction, thereby saving the length along the extension direction of the first side plate 20.

The tail plate 42 is disposed on the base plate 41, and both ends of the tail plate 42 are respectively connected to the first support plate 43 and the second support plate 44, so that the base plate 41, the first support plate 43, the second support plate 44, and the tail plate 42 can enclose and form an accommodating space, thereby ensuring that the engine assembly can be accommodated in the accommodating space, avoiding collisions, and improving safety during use.

[0047] Specifically, in this embodiment, in order to facilitate the arrangement of the frame 1 on the vehicle, the base plate 41 is generally arc-shaped. This arrangement can also improve the structural strength of the fixing frame 40 and ensure safe use.

[0048] Specifically, in this embodiment, the first support plate 43, the second support plate 44, and the tail plate 42 are all connected to the base plate 41 by welding.
