Abstract
The invention discloses a single-spiral driving travel mechanism, belonging to vehicle travel systems. The technical proposal is as follows: a plumb in the middle of the front end of a body 1 is fixedly connected with a steering shaft 2 and two anti-turning wings 12 are respectively and symmetrically fixedly connected with two sides of the plumb. A propelling spiral 3, a spiral shaft 4, a cylindrical gear 5, an idler gear 6 and a driving gear 7 form a spiral propelling device; a guide spiral 8, a guide shaft 9 and a steering cover 10 form a power guide device; the guide shaft 9 is coupled with the spiral shaft 4 through a universal coupling 11; the steering cover 10 is rotationally coupled with the steering shaft 2 and the coupling is controlled by a turn angle Alpha; and the driving power is transmitted through the driving gear 7 to drive the single-spiral driving travel mechanism to travel on the plants, earth surface or in desert and marsh, etc., soft environment through the spiral propelling device and the power guide device. The driving travel mechanism can be applied to the secret travel for monitoring or detection, etc.
Description
Technical field
The present invention relates to a kind of single spiral drive running mechanism, belong to the vehicle to run system.Be to have made up cylindrical screw to advance a kind of low level traveling gear that leads with trochoid spiral, be used for walking under the soft environment such as vegetation, upper soll layer or desert, marsh etc., realize having walking functions such as the disguised scouting that requires, monitoring.
Technical background
The low level traveling gear can satisfy on the vegetation top layer, requirement such as walking such as the crypticity of the scouting of mellow soil environment, monitoring etc., also can finish monitoring for special ecological environment such as marsh, forests, detect the walking needs.
That the driver train that is used to walk mostly is is wheeled, crawler type, sufficient formula, screw drives mechanism can adapt to softer or have the environment of rheological behavior medium, the helicallobe that is used for walking when driving advances under the condition of any sliding ratio and all can not produce soil-shifting phenomenon and part helicallobe and bury and sink into the medium of walking, and can be used for the low level walking.But there is Dalian University of Technology's design-calculated earthworm-type crawl device in 2004 in the mechanism of low level walking at present, has low level walking advantage.Single spiral drive running mechanism is a kind of novel low level traveling gear, has the special complex environment of adaptation and cross-country traveling advantage.
Summary of the invention
The objective of the invention is mechanical characteristic based on helical structure, provide a kind of cylindrical screw to advance the low level traveling gear that leads with trochoid spiral, can under soft environment such as vegetation, upper soll layer or desert, marsh etc., walk, can be applied to crypticity walkings such as monitoring, scouting.
Comprise in order to reach the technical scheme that purpose of the present invention takes: body 1 front center vertical is fixed with steering shaft 2, the bilateral symmetry level is connected and prevents rotor 12, advance spiral 3 to be connected by screw shaft 4 and cylindrical wheel 5 coaxial lines, screw shaft 4 rotates connection on body 1, cylindrical wheel 5 is by intermediate gear 6 and driving gear 7 dead axle line engaged transmission, form spiral pushing device by 3-4-5-6-7, be connected with the axis of guide 9 coaxial lines with the guiding spiral 8 that advances spiral 3 with rotation direction, the axis of guide 9 is turning to rotation connection on the cover 10, form the power guid device by 8-9-10, the axis of guide 9 connects with screw shaft 4 by universal-joint 11, turning to cover 10 to rotate with steering shaft 2 connects, control by corner α, propulsive effort drives the traveling gear motion by driving gear 7 inputs, forms to be driven by spiral pushing device, single spiral drive running mechanism (as Fig. 1) by the power guid device guiding.Turn to the angle α of cover 10 and steering shaft 2 by adjusting, realize the adjusting of direction in the walking process with angle in the horizontal surface that changes the axis of guide 9 relative screw shafts 4, the ground medium is decomposed into along the drive force traveling gear of working direction the application force of spiral and advances in the walking process, anti-rotor 12 balances that side force is provided with by bilateral symmetry guarantee the stability that mechanism walks.
In the above-mentioned single spiral drive running mechanism, can replace cylindrical wheel 5 and driving gear 7 to save intermediate gear 6, replace gear transmission, can satisfy the demand of travelling equally by chain-driving by two sprocket wheels.
