Problems solved by technology
[0002] In the process of modern agricultural development, in order to improve labor productivity, agricultural mechanization is developing faster and faster, sowing, spraying and harvesting equipment have been relatively mature. In the existing agricultural mechanization equipment, the wheel base and height of the mechanical chassis are often fixed. , can only be applied to specific crops, but in the process of field management and crop growth, crop planting width and crop growth height are often different, these mechanical equipment cannot meet the requirements of multi-crop multi-period application

The invention discloses a vehicle chassis. The vehicle chassis comprises a vehicle frame, a power device, a steering device and two wheel assemblies. Each wheel assembly comprises two wheels, two wheel frames, a transmission assembly, a wheel track adjusting assembly and a first steering pull rod. Each transmission assembly comprises a differential mechanism and two first transmission shafts. The first transmission shafts, the wheel track adjusting assemblies and the first steering pull rods are all length-adjustable components. The steering device comprises a steering oil cylinder, a second steering pull rod support and two second steering pull rods. Through the arrangement of the wheel assemblies, the combination of three functions is provided, the wheel tracks of the vehicle chassis can be adjusted, the vehicle chassis is high, trafficability is good, four-wheel steering is achieved, the steering radius is small, meanwhile, due to the four-wheel drive arrangement, the vehicle chassis can be barely affected by the working ground condition, and the situation that the vehicle chassis travels difficultly on a rugged road surface is avoided.
Description
technical field [0001] The invention relates to a vehicle chassis. Background technique [0002] In the process of modern agricultural development, in order to improve labor productivity, agricultural mechanization is developing faster and faster, sowing, spraying and harvesting equipment have been relatively mature. In the existing agricultural mechanization equipment, the wheel base and height of the mechanical chassis are often fixed. , can only be applied to specific crops, but in the process of field management and crop growth, crop planting width and crop growth height are often different, these mechanical equipment cannot meet the application of multiple crops and multiple periods. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vehicle chassis with adjustable wheelbase, good passability and four-wheel steering. [0004] In order to solve the above problems, the present invention includes a vehicle fram...
