Vehicle chassis height regulating suspension and vehicle with same

Abstract

The invention relates to the technical field of vehicle parts, in particular to a vehicle chassis height regulating suspension and a vehicle with the suspension. The vehicle chassis height regulating suspension comprises a vehicle frame fixedly connected with a vehicle chassis and support rods (4) which are fixedly connected with wheel shafts (6) of the vehicle in vertical direction, and a parallelogram connecting rod mechanism is connected between the vehicle frame and the support rods (4); and the vehicle frame can adjust the height in the vertical direction relative to the positions of wheels. According to the vehicle chassis height regulating suspension and the vehicle, provided by the invention, the height of the vehicle chassis can be actively adjusted, an adjustment range exceeds the diameter of tires of the wheels, the height of the vehicle chassis is increased, the passing ability of the vehicle is greatly changed so as to adapt to the operation requirements of crops during the middle and late growth stages and long-stalked crops on farmland machinery, and the height of the vehicle chassis can be further reduced to adapt to the requirements of the crops during the early growth stage and short crops on farm work.

Description

technical field [0001] The invention relates to the technical field of vehicle components, in particular to a vehicle chassis height adjustment suspension and a vehicle with the suspension. Background technique [0002] With the development of agricultural mechanization in our country and the improvement of people's living standards, people put forward higher requirements for farmland operation machinery. After field crops are planted, field management operations such as cultivating, weeding, spraying pesticides and fertilizing all have high requirements on the passability of agricultural machinery, so it is more urgent to actively adjust the height of the vehicle chassis to improve the passability of vehicles. As crops increase in height during growth and field management operations for taller crops often require adjustments beyond the tire diameter. At present, there are many ways to adjust the height of the chassis of the vehicle. The invention patent with the applicatio...

Problems solved by technology

At present, there are many ways to adjust the height of the chassis of the vehicle. The invention patent with the application number of 200610018159.1 includes an air suspension, which can realize the change of the height of the chassis from the ground through the inflation and deflation of the air spring, but the adjustment amount is small. , far from meeting the chassis height requirements of field vehicles

The invention patent with the application number 200510084634.0 changes the height of the suspension support relative to the vehicle body through the height control device, which can indirectly adjust the height of the car chassis within a certain range and improve certain comfort and stability, but the structure is complicated and the cost is high. Poor rigidity, mainly used in cars, and due to structural limitations, the adjustment amount is small, and it still cannot meet the requirements of large-scale adjustment of the chassis height of the vehicle during field management operations during the entire growth process of farmland crops
