Description
Technical field
This utility model relates to a kind of trailing wheel of car, particularly relates to a kind of cat ladder driven pulley for electric wheelchair.
Background technology
Wheel be between tire and and axletree between bear the rotary components of load, be usually made up of (GB/T2933-1995) two critical piece wheel rims and spoke.Wheel rim is the parts of installation and supporting tire on wheel, and spoke is the support unit on wheel between axletree and wheel rim.Wheel, except above-mentioned parts, also comprises wheel hub sometimes.
Common wheel is that an axle connects a tire.Due to the development and progression along with society, the demand of use can not be met under some conditions.On medical wheelchair upstairs going cart, need different wheels to provide kinematic mount.
Utility model content
The purpose of this utility model is a kind of wheelchair driven pulley of design, and this takes turns when moving on level road is translational motion, and this kind of wheel has rolling cat ladder function.
In order to realize above object, the technical solution adopted in the utility model: a kind of cat ladder driven pulley for electric wheelchair, is characterized in that: it comprises symmetry and is arranged on two mount pads (7) in car and the wheel mechanism by being connected with connecting axle (6); Described wheel mechanism is made up of holder housing (1), connecting axle (6), movement output wheel (5), axletree (4), motion wheel for inputting (3), wheel (2); Connecting axle (6) is taken turns (5) rigid coaxial and is connected with movement output, connecting axle (6) and movement output are taken turns (5) and be arranged on holder housing (1) centre position; Described holder housing (1) comprises the first housing (11) and the second housing (12) fastening forms; Axletree (4) is connected with motion wheel for inputting (3) rigid coaxial, and axletree (4) and motion wheel for inputting (3) quantity are that three covers are evenly arranged in movement output and take turnss (5) surrounding; Connecting axle (6) is arranged on holder housing (1), and axletree (4) is arranged on holder housing (1), and axletree (4) connects wheel (2).
Described the first housing (11) is provided with a groove (111), described the second housing (12) is provided with a projection (121).
The beneficial effects of the utility model: this utility model is exclusively used in medical wheelchair upstairs going cart, and this wheel can not only parallelly be walked, can tumbling motion when encountering barrier, improves the cat ladder ability of wheel.This utility model structure is simple, and manufacturing cost is lower, may be used for the field such as toy, upstairs going cart.Uniform layout makes this drive mechanism have good mechanical property, long service life.
Accompanying drawing explanation
Fig. 1 is structural configuration schematic diagram of the present utility model.
Fig. 2 is integrated three-wheel wheel schematic diagram.
Detailed description of the invention
As shown in Figure 1 and Figure 2, anatomical connectivity of the present utility model closes and is: it comprises symmetry and is arranged on two mount pads 7 in car and the wheel mechanism by being connected with connecting axle 6; Described wheel mechanism is made up of holder housing 1, connecting axle 6, movement output wheel 5, axletree 4, motion wheel for inputting 3, wheel 2; Connecting axle 6 and movement output are taken turns 5 rigid coaxial and are connected, and connecting axle 6 and movement output are taken turns 5 and be arranged on holder housing 1 centre position; Described holder housing 1 comprises the first housing 11 and the second housing 12 fastening forms; The first described housing 11 is provided with a groove 111, the second described housing 12 is provided with a projection 121.Axletree 4 is connected with motion wheel for inputting 3 rigid coaxial, and axletree 4 and motion wheel for inputting 3 quantity are that three covers are evenly arranged in movement output and take turns around 5; Connecting axle 6 is arranged on holder housing 1, and axletree 4 is arranged on holder housing 1, and axletree 4 connects wheel 2.
This utility model is under the driving of driving wheel, wheel 2 rotates, and wheel 2 passes motion to axletree 4, and axletree 4 passes motion to motion wheel for inputting 3, motion wheel for inputting 3 passes motion to movement output wheel 5, and movement output wheel 5 passes motion to connecting axle 6.Use this utility model when climbing ladder, wheel entirety can with connecting axle 6 for center of rotation.
It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise which key element, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising key element and also there is other identical element.
Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.The above is only preferred implementation of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite not departing from this utility model principle, some improvement, retouching or change can also be made, also above-mentioned technical characteristic can be combined by rights; These improve retouching, change or combination, or the design of utility model and technical scheme are directly applied to other occasion without improving, and all should be considered as protection domain of the present utility model.
