A method for deformation and heightening of crawler chassis

Abstract

The invention provides a method for increasing deformation of a crawler belt bottom plate. The method includes the steps that firstly, a crawler belt is quadrilateral and the height of a bottom plateframe from the ground is small, a travel driving mechanism drives driving wheels to rotate, and crawler belt wheels carry a whole machine to travel on a flat outdoor ground; then, when the crawler belt wheels are required to carry the whole machine on an undulating outdoor ground to travel, a deformed driving mechanism transfers the power to a deformed screw rod and drives the deformed screw rod to rotate. The deformed screw rod rotates to enable deformation sliding blocks to slide close to each other. Push-pull rods pull I-shaped frames which are symmetrically arranged up and down to rotate the I-shaped frames away from each other around first movable shafts, until the two I-shaped frames form a flat angle. A mounting block moves vertically upwards, the bottom plate frame can move synchronously upwards and the height from the ground is increased, and meanwhile a tensioning mechanism supports the crawler belt outwards and enables the crawler belt from quadrilateral to hexagon; and finally, the travel driving mechanism drives the driving wheels to rotate, and the crawler belt wheels can carry the whole machine on the undulating outdoor ground to travel.

Description

technical field [0001] The invention relates to a crawler chassis, in particular to a deformation and heightening method for the crawler chassis. Background technique [0002] Tracked chassis has a very wide range of applications. Compared with ordinary tire chassis, it has very significant rigidity and strength. Its walking environment is harsh, mostly outdoor terrain, so it is used in agricultural machinery, military machinery, and outdoor exploration and survey machinery. For example, for harvesters, tractors, rice transplanters, tanks, outdoor survey robots, etc., after searching, it is found that the crawler chassis mainly includes track wheels arranged symmetrically on the left and right and the chassis frame fixedly connecting the two. The track is composed of pulley and tensioning device. The shape of the track winding around the driving wheel, supporting pulley, and tensioning device is a rectangle or a forward-leaning parallelogram. The disadvantage of the current ...

[0002] Tracked chassis has a very wide range of applications. Compared with ordinary tire chassis, it has very significant rigidity and strength. Its walking environment is harsh, mostly outdoor terrain, so it is used in agricultural machinery, military machinery, and outdoor exploration and survey machinery. For example, for harvesters, tractors, rice transplanters, tanks, outdoor survey robots, etc., after searching, it is found that the crawler chassis mainly includes track wheels arranged symmetrically on the left and right and the chassis frame fixedly connecting the two. The track is composed of pulley and tensioning device. The shape of the track winding around the driving wheel, supporting pulley, and tensioning device is a rectangle or a forward-leaning parallelogram. The disadvantage of the current track chassis is that the shape of the track wheel is fixed and cannot be deformed. As a result, the height of the chassis frame from the ground is constant, and the passing performance is poor, especially when traveling on undulating outdoor ground. In order to solve the problems pointed out by the above shortcomings, it is necessary for the present invention to provide a chassis frame with an ingenious structure, simple principle, and an adjustable chassis frame height from the ground. , High-performance variable track chassis for outdoor off-road use
