Vehicle chassis height adjusting device and vehicle applying same

Abstract

The invention belongs to the field of vehicle walking, and discloses a vehicle chassis height adjusting device. The vehicle chassis height adjusting device comprises a frame which is fixedly connected with a vehicle chassis, wheels, and a crank double-slide-block mechanism which is fixedly connected to the frame, wherein slide block rocker mechanisms are connected between the frame and the wheels, and share the same slide block. Apart from the crank double-slide-block mechanism in the vehicle chassis height adjusting device, the two groups of slide block rocker mechanisms are symmetrically distributed by taking the vertical bisector of the wheel base of a vehicle as the central line. By adopting the device, the height of a vehicle chassis can be adjusted actively, the adjusting range surpasses the tire diameter of each wheel, and the wheel base of a vehicle can be kept constant during height adjustment. A vehicle applying the device is further provided. By increasing the height of the vehicle chassis, the trafficability is improved in order to adapt to middle and later growing periods of crops and field management operation requirements of high-stalk crops. The height of the vehicle chassis can be reduced to adapt to the primary period of crops and the field management operation requirements of low crops.

Description

technical field [0001] The invention belongs to the field of vehicle running, in particular to a vehicle chassis height adjustment device and a vehicle using the device. To meet the operational requirements of field management during the crop growth period. Background technique [0002] my country's agricultural machinery is developing rapidly. In field management operations, spraying, weeding, fertilizing, and intertillage are important links. Therefore, people have put forward higher requirements for agricultural machinery, especially plant protection machinery. As the height of the chassis is higher, the passability is better. Therefore, there is an urgent need to greatly adjust the height of the vehicle chassis steplessly to improve the vehicle's passability to meet the crop field management requirements. With the increase in height during crop growth and field management of high-stalk crops, the adjustment range usually needs to exceed the tire diameter. [0003] In ...

AI Technical Summary

Problems solved by technology

There are currently many ways to adjust the height of the vehicle chassis. For example, the invention patent application number 201110457954.1 includes a vehicle chassis height adjustment suspension and a vehicle with the suspension. By adjusting the parallelogram between the frame and the wheels The mechanism makes the height of the frame relative to the wheel position adjustable in the vertical direction, which can greatly increase the height. However, when the height is adjusted through the parallelogram mechanism, the wheelbase of the vehicle is changed, which increases the difficulty of power transmission and steering problems.
