Description

A kind of running gear
Technical field
The present invention relates to a kind of running gear, belong to the vehicle to run chassis, can improve the crossing ability of vehicle and the comformability of complicated ground.
Technical background
The wheel mounting means that uses on the vehicle mostly is the direct and transmission shaft connection of wheel at present, and the chassis height basic fixed of vehicle maybe can only be carried out small adjusting by suspension like this.If the chassis height, then vehicle body stable poor in motion particularly caused rollover easily, and traffic accident takes place when higher speed travels or turns.Vehicle chassis is too low, and when when pavement conditions is poor, such as muddy, rough and uneven in surface road surface, the vehicle chassis ratio is easier to bump or rub with ground, and trafficability is poor.
Large-scale load-carrying vehicle chassis is mostly supported by a plurality of vehicle bridge, and the chassis is constructed of rigid materials, may occur the unsettled phenomenon of part wheel when by scraggly road, has reduced the load-carrying ability and the crossing ability of vehicle.
1979 the 4th phase papers of " trac. and agriculture truck " " a kind of trac. before and after crack, bridge ground adjusting mechanism " are respectively by the direct jack-up vehicle body of hydraulic actuating cylinder and satellite gear revolution adjusting propons and crack, back axle ground, and mechanism is huge and not to the ground profiling.The planet gear type lunar rover vehicle that in May, 2000 paper " design of New Omni-directional Crossing Obstacle Mechanism " of " machine design and manufacturing engineering " proposes can profiling ground but can not be regulated the crack, ground.
Summary of the invention
The objective of the invention is to provide a kind of and can regulate the vehicle chassis height significantly, and can realize running gear road, ground profiling.It can change the height of gravitational center of vehicle, makes vehicle adapt to different ground, road, improves the through performance of vehicle; It can also make set of wheels that rugged, scraggly road profiling is travelled simultaneously, improves vehicle to ground-surface comformability and cruising characteristic.
In order to reach the identical basic wheels of structure that technical scheme that purpose of the present invention takes comprises vehicle frame 1 and four individual drive, each basic wheels comprises the axle housing 2 that is connected with vehicle frame 1, the axle drive shaft 3 that in axle housing 2, rotates, with the belt wheel 4 and 4 of axle drive shaft 3 coaxial rotation ', connecting rod 5 and 5 ', axletree 6 and 6 ', with the belt wheel 8 of axletree 6 coaxial rotation and wheel 7 and with the belt wheel 8 of axletree 6 ' coaxial rotation ' and wheel 7 ', be with 9 and 9 ', hydraulic actuating cylinder 10, be with 9 on belt wheel 4 and belt wheel 8, to constitute strap drive, the two ends of connecting rod 5 are enclosed within on axle drive shaft 3 and the axletree 6 also free to rotate respectively, be with 9 ' around belt wheel 4 ' and belt wheel 8 ' on constitute strap drive, connecting rod 5 ' two ends be enclosed within axle drive shaft 3 ' and axletree 6 ' go up and free to rotate respectively, the two ends of hydraulic actuating cylinder 10 respectively with connecting rod 5 and 5 ' be connected with revolute pair.The basic wheels of four individual drive form the full-time driving running gear of full wheel when driving simultaneously, flexible adjustment connecting rod 5 and 5 by hydraulic actuating cylinder 10 cylinder bars ' angle α, thereby regulate the crack, ground of running gear, by connecting rod 5 and 5 ' realize wheel 7 and 7 ', realize that by the driving rotating speed that changes the basic wheels in both sides running gear turns to ground-surface profiling around axle drive shaft 3 servo-actuateds.
In the above line walking apparatus, strap drive is replaced by chain-driving, be about to belt wheel 4 and 4 ', belt wheel 8 and 8 ' be replaced by sprocket wheel, be with 9 and 9 ' be replaced by chain, constitute chain-driving form of the present invention.
In the above line walking apparatus, with the strap drive of basic wheels be replaced by n level spur gear drive (positive integer n=2,3,4 ...), the power of axle drive shaft 3 and Motion Transmission give wheel 7 and 7 ', constitute multi-stage gear type of belt drive of the present invention.
In the above line walking apparatus, the basic wheels in two of two basic wheels of fwd or back cut off the power input or remove be with 9 and 9 ', running gear becomes back-wheel drive or front-wheel drive.
The present invention can regulate vehicle frame apart from ground-surface height by above-mentioned basic wheels, realizes ground-surface profiling, improves crossing ability and the comformability of vehicle to Different Ground.
