Abstract
The utility model discloses a trolley which is driven by gravitational potential energy and has a direction control function. A period and swing of the trolley can be adjusted. The trolley consists of a dial, a front shaft, a front wheel, an L-shaped rocker, a connecting rod, a trolley body, a pin, a steering wheel, a belt, a support, a driven wheel, an ear, a belt wheel, a cone wheel, a fixed pulley, a spindle and a driving wheel. All energy for driving the trolley is from the given gravitational potential energy, motion is transferred to a steering mechanism by belt transmission, and the steering mechanism achieves a steering function by using a principle of a crank and rocker mechanism. The swing of the trolley can be controlled by adjusting the length of a crank, and period adjustment can be achieved by changing a transmission ratio of the belt transmission. An indicator and the dial are mounted at the front part of a trolley head of the trolley, so that alignment of the trolley head is facilitated.
Description
Technical field
The utility model relates to a kind of novel dolly driven with gravitional force, belongs to field of mechanical technique.
Background technology
With gravitional force, drive, and voluntarily controlling party to carbon-free dolly be the 3rd national college students' engineering training integration capability contest exercise question, require a kind of dolly of design, the energy that drives its walking and turn to all derives from given gravitional force,, and but the steering mechanism of dolly has regulatory function, can independently avoid the obstacle (at interval of 90cm-110cm, placing the high 200mm round log of diameter 20mm rod) on racing track.
Summary of the invention
The purpose of this utility model is to have designed a kind of with the gravitional force driving, and has the dolly of direction controlling function, but the steering mechanism of dolly has regulatory function, the corner size in the time of can adjusting moving of car as requested and the length in cycle simultaneously.Be achieved through the following technical solutions:
A kind of dolly with direction controlling function, be comprised of dial, front axle, front-wheel, " L " shape rocking bar, connecting rod, vehicle body, pin, steering wheel, belt, support, driven pulley, ear, belt wheel, taper cone pulley, fixed pulley, main shaft, driving wheel; Dowel ends twisting in described connecting rod one end and steering wheel, the other end is nested on " L " shape rocking bar, the rocking bar other end and front axle gummed; Open an elongated slot in described steering wheel, can adjusting pin be pinned to the distance of steering wheel centre, the length of crank can be regulated; Described connecting rod is adopted to be threaded by a stock and base and forms, and the length of connecting rod can be regulated half pitch at every turn.
The utility model is the advantage of prior art relatively:
1, adopt the band transmission, move more steady than gear drive, manufacturing process is simple simultaneously.
2, adopt the principle control of crank connecting link to turn to, simple in structure.
3, by adjusting on steering wheel pin to the distance of steering wheel centre, and the length of adjustment connecting rod, can change amplitude of oscillation size and the corner of moving of car track.
4, contain a plurality of grooves on small pulley, and the diameter of groove do not wait, can regulate the gearratio between small pulley and steering wheel, change the cycle length of movement locus.
When 5, dolly starts, wire-wound is on taper cone pulley, and now detent torque is large, is convenient to start.
6, on the dolly front axle, pointer is housed, body forward structure is equipped with dial, and whether the pivot angle of front-wheel in the time of can accurately adjusting dolly and dispatch a car can be observed easily dolly left and right pivot angle simultaneously and equate.
The accompanying drawing explanation
Fig. 1 is the carbon-free vehicle structure schematic diagram of direction controlling function that has described in the utility model.
The specific embodiment
The 1-dial; The 2-front axle; The 3-front-wheel; 4-" L " shape rocking bar; The 5-connecting rod; The 6-vehicle body; The 7-pin; The 8-steering wheel; The 9-belt; The 10-support; The 11-driven pulley; The 12-ear; The 13-belt wheel; The 14-taper cone pulley; The 15-fixed pulley; The 16-main shaft; The 17-driving wheel.
Below in conjunction with the embodiment accompanying drawing, the utility model is described further.
As shown in Figure 1, be the carbon-free dolly with turning function described in the utility model.When main shaft 16 rotates, belt wheel 13 synchronously rotates, and drives steering wheel 8 by belt 9 and rotates.Described steering mechanism is comprised of front axle 2, " L " shape rocking bar 4, connecting rod 5, steering wheel 8.Have elongated slot on steering wheel 8, for pin 7 is installed, connecting rod 5 one ends and pin 7 are hinged, and the other end is enclosed within on " L " shape rocking bar 4 brachycephaly, and the other end of " L " shape rocking bar 4 and front axle 2 glued joint.During motion, steering wheel 8 is around its central rotation under the effect of belt 9, and pin 7 can drive link 5 seesaw, thereby connecting rod 5 drives the swing centered by front axle 2 axis of " L " shape rocking bar 4, so just realized turning function.
