Problems solved by technology

The foot type is a striding type of walking, which has a strong ability to overcome obstacles. However, under the same load, the foot type walking method has a large contact pressure and a small load-bearing capacity, and is suitable for walking on roads with high load-bearing pressure; the crawler-type walking method has ground contact The pressure is small, the load-bearing capacity is large, and the adhesion is strong, so it can walk on the ground with low load-bearing pressure; while the contact pressure and load-bearing capacity of the wheel type are between the foot type and the crawler type, it can run at high speed and has high flexibility, but poor ability to overcome obstacles

Embodiment Construction

[0019] specific implementation plan

[0020] Embodiments of the present invention will be described below according to the accompanying drawings.

[0021] As shown in FIG. 1 , 1 is a vehicle frame, and this embodiment includes n=2×2 basic wheel sets, that is, 4 basic wheel sets are arranged on the vehicle frame 1 in 2 rows and 2 columns. Each basic wheel set comprises a shock absorber 2, an axle 3, a drive wheel 4 and a rotating guide rod boosting mechanism, and the rotating guide rod boosting mechanism includes a crank 5, a connecting rod 6, a rotating guide rod 7 and a slide block 8, each The basic wheel set is fixedly connected with the vehicle frame 1 through respective shock absorbers 2 . The position of the connecting rod 6 is locked by the azimuth angle, that is, the included angle α, -180°≤α<180°;

[0022] It can be seen from Figure 1 that each basic wheel set has an independent driving wheel 4, and the driving wheel 4 can drive the system to run; by changing the spe...

Abstract

The present invention is one kind of mechanically boosting walking mechanism and belongs to the field of vehicle chassis. Technologically, the mechanically boosting walking mechanism includes one frame and several independent basic wheel sets. Each of the basic wheel sets includes one damper, one wheel shaft, one driving wheel, and one boosting rotation guide rod mechanism, which comprises crank, link rod, guide rod and sliding block. The boosting rotation guide rod mechanism in simple structure increases the driving force to raise the obstacle crossing capacity of the wheel type walking mechanism and expand the ground adapting range of the wheel type walking mechanism, so as to meet different requirements.

Description

technical field [0001] The invention relates to a mechanical booster walking system, which belongs to the vehicle walking chassis. This kind of mechanical power-enhanced walking system uses the method of increasing the mechanical driving force to assist the telescopic driving rod in the wheeled walking mechanism with large load capacity and adhesion, so that the walking system has a strong ability to cross obstacles and can It is suitable for traction or walking with loads on muddy, uneven and complex roads with many weeds and trees, as well as in fields, swamps, mountains, hills and other conditions. technical background [0002] In order to meet the current needs of forest disaster relief, human beings put forward higher and higher requirements for the trafficability and adaptability of the walking system, requiring the walking system to be used for operations and emergency rescue in areas where people cannot enter or are difficult to enter. At present, the commonly used ...
