Adjustable electric agricultural vehicle chassis

Abstract

The invention relates to an adjustable electric agricultural vehicle chassis. The adjustable electric agricultural vehicle chassis comprises a chassis main body bracket, wherein a power device is arranged in the chassis main body bracket; a front frame and a rear frame are symmetrically arranged at two ends of the chassis main body bracket; handle stems are symmetrically arranged on two sides of the power device, and the power device are separately and rotatably connected with a rear axle and a front axle through the handle stems; damper assemblies are symmetrically arranged on two sides of the upper end of the chassis main body bracket; and the damper assemblies at two ends are separately connected with the rear axle and the front axle. According to the adjustable electric agricultural vehicle chassis, the distance between the front axle and the rear axle can be adjusted at any time by adjusting the damper assemblies, so that the distance between the front axle and the rear axle is shortened, the turning radius of a vehicle is reduced during turning, and the vehicle can easily pass through narrow corners; and the height of the middle position of the chassis can be raised or lowered to ensure that the vehicle passes through road surfaces with various road conditions, raise the height of the chassis on roads with bad road conditions to ensure that the vehicle can pass smoothly,the height of the chassis is reduced on smooth roads to reduce resistance, and simple structure and low cost are achieved.

Description

technical field [0001] The invention belongs to the field of vehicle chassis, and in particular relates to an adjustable electric agricultural vehicle chassis. Background technique [0002] As the core component of agricultural vehicles, the chassis of agricultural vehicles is equipped with chassis frames, front axles, rear axles, drive shafts, drive axle components, power units, transmission assemblies, steering systems and other components. The above systems are in different The frame structure and layout of vehicles are not the same, but the completed functions are the same, that is, to transmit the power of the power plant to the wheels, and then convert the torque transmitted to the wheels into thrust against the ground, and the ground gives the wheels a reaction force ——Traction force, and finally transmit the traction force to all parts of the car to ensure the normal driving of the vehicle; change or restore the driving direction of the car; slow down or stop the car...

AI Technical Summary

Problems solved by technology

Based on the economic situation of agricultural vehicle users, the chassis length and height of existing agricultural vehicles are generally fixed and cannot be adjusted, which affects the passing performance of the vehicle and leads to a decrease in the maneuverability of the vehicle. When driving on uneven or sharply turning roads , the chassis is easy to contact with the ground, making it difficult to bump, scratch or turn the chassis parts. When driving on a flat road, the chassis cannot be lowered, which will increase the resistance; on the other hand, most agricultural vehicles are driven by front or rear wheels. When the driving wheel is blocked or overhead, it loses power and is not flexible enough

Therefore, for some vehicles that need to be driven on complex and changeable roads with bad road conditions, or have special requirements, the structure of the chassis needs to be further improved.
