Abstract
The utility model relates to a wire-driven invalid's vehicle, comprising a vehicle frame, a vehicle shaft, two rear wheels and a front wheel. The utility model is characterized in that the wheel head of the rear wheel is designed to a wire-driven wheel head, the lower side beam of the vehicle frame is provided with a driving pull rod, and the outer end of a wire rope on the rear wheel head is connected with the pull rod via a pulley. The driving pull rod can be provided with a variable speed sliding sleeve, a braking mechanism can be arranged on the rear wheel, and a guiding pedal can be arranged on the front wheel. The utility model has the advantages of reasonable design, simple structure, labour saving, high speed, stepless speed change, flexible turning, good guiding performance and safety, which is an ideal and practical invalid's vehicle.
Description
This utility model belongs to people with disability's articles for use technical scope, relates to a kind of people with disability's car.
People with disability's car of prior art has two types substantially, and a kind of is directly to move wheel secondary circle drive-type, this drive-type people with disability car, and speed is slow, and it is big to consume one's strength; Another kind is the driven by shaking formula, this people with disability's car, and speed is also slow, can not speed change, it is bigger to consume one's strength, the turning underaction, and when turning, influence driven, does not have yet brake gear is arranged, appearance danger easily.
Task of the present utility model provides and a kind ofly can realize that infinitely variable speeds, speed are fast, it is little to consume one's strength, flexible, the safe and reliable line transmission people with disability car of turning, to overcome the existing existing above-mentioned defective of people with disability's car.
Task of the present utility model is to improve to realize on the basis of existing people with disability's car, it comprises vehicle frame, axletree, two trailing wheels and a front-wheel of existing people with disability's car, its main points are that the wheel head of trailing wheel adopts line drive head, active mode on the bottom curb girder of vehicle frame is installed the driving pull bar, and the steel wire rope outer end of line drive head is walked around a fixed pulley and is connected on this driving pull bar.
Fig. 1 is a front view of the present utility model
Fig. 2 is a side view of the present utility model
Below in conjunction with accompanying drawing this utility model is elaborated:
According to Fig. 1, shown in Figure 2,14 is vehicle frames among the figure, the following horizontal entrucking axle 9 of vehicle frame, and there is trailing wheel 1 at the two ends of axletree 9, the wheel of this trailing wheel 2 is a line drive head, for example adopt application number 92211396.3, name to be called the line transmission wheel header structure of back wheel voluntarily, rope pulley 4 is established in the inner of hub, tightly is enclosed within on the centrifugal shelves 3, the outside dress coil spring box 6 of rope pulley, coil spring box is fixed on the axletree 13, and the outer end and the coil spring box of wind spring are connected and fixed, and inner and centrifugal shelves 3 link to each other.Be equiped with driving pull bar 15 in active mode on the bottom curb girder of vehicle frame 14, the outer end of the steel wire rope 20 of line drive head 2 is walked around the fixed pulley 8 that is located on the vehicle frame and is connected on this pull bar 15; The front end of vehicle frame 14 is equipped with universal front-wheel 11.Two hands times spent are the pull bar 15 of push-and-pull both sides respectively, by steel wire rope 20 trailing wheel is rotated, thereby drives to advance; When needs were turned, one hand was firmly moved a lateral bracing strut, or simultaneously opposite side was braked, and making two-wheeled produce differential can realize.
For adapting to the requirement of different road surfaces and travel speed, can also be on pull bar 15 suit one speed change sliding sleeve 10, the outer end of above-mentioned said steel wire rope 20 is connected on the pull bar 15, can be attached thereto by this sliding sleeve, and on sliding sleeve 10 dress handle 18, the front end of handle 18 is established friction plate 16, and compression spring 17 is established at the rear portion.Hold sliding sleeve 10 and handle 18, overcome compression spring 17 pressure, make friction plate 16 leave pull bar 15, sliding sleeve 10 can be under the effect of hands, slide up and down to arbitrary position along pull bar 15, release handle 18, friction plate 16 is under the effect of compression spring 17, be pressed on pull bar 15 location, thereby realize the height infinitely variable speeds.
Requirement for adapting to different road surfaces and running at high speed and take a sudden turn prevents peril, and trailing wheel of the present utility model can be provided with brake gear, establishes brake shoe 7 on trailing wheel 1, establishes brake lever 12 on pull bar 15, connects by backguy.In the time of need slowing down or stop, but both hands be held the brake lever brake, when needs are turned, when particularly taking a sudden turn, can brake by a brake lever that hold a side, and according to circumstances, another hands also can continue to drive, and realizes zig zag soon.
For adapting to the requirement of relatively poor road traveling, strengthen steering capability, also can in the guiding rotating shaft of front-wheel 11, establish a guiding pedal 19, when in case of necessity, can step on pedal, under the effect of foot, carry out forced guiding.
This utility model is reasonable in design, and is simple in structure, laborsaving, and speed is fast, and can realize infinitely variable speeds, turns flexibly, and steering capability is good, and is safe and reliable, is present comparatively ideal a kind of people with disability's car.
