Description
Technical field
The utility model relates to trackless terrestrial vehicle, is specifically related to the wheel of trackless terrestrial vehicle, particularly both can be on the level land level walking, can stir again climb ladder step on the building wheel.
Background technology
The wheel of traditional trackless terrestrial vehicle all is to be connected with car body by axle by single wheel, the continuous and ground touch scrolling realization vehicle operating of wheel.Be provided with the vehicle of this wheel, can only travel on smooth road surface, in case run into steeper projection (as stair etc.), difficulty just takes place in vehicle operating.
In order to overcome this problem, people have carried out number of research projects, Chinese patent CN2051919U discloses " a kind of Pan Lou, level land multiservice car ", it realizes that by loading onto satellite gear at the transverse axis two ends of vehicle body this satellite gear is actually a driven train of being made up of 4 steamboats and wheel carrier.Though the train of this structure can be used on the manpower push-and-pull vehicle, only limit to use on the manpower push-and-pull vehicle during its operation, hard especially, and dangerous, thereby be difficult to apply.
Chinese patent CN2209099Y disclosed " Climbing wheel ", it steps on the building wheel for a kind of star-wheel satellite gear reversible type, and this Climbing wheel comprises wheel carrier, the wheel with 3-8 radial pivoted arm, and wheel is arranged on the end of each pivoted arm of wheel carrier; Wheel carrier is by a center shaft and body contact; Be provided with sun gear on center shaft, be respectively equipped with coaxial driven gear (planetary wheel) on the axle of each wheel, be respectively equipped with idle pulley between sun gear and each planetary wheel, sun gear and idle pulley are meshing with each other, and idle pulley and planetary wheel are meshing with each other.This Climbing wheel respectively is provided with claw-type clutch on end of sun gear and wheel carrier, sun gear can freely rotate on center shaft, having the part of spline to be provided with on the center shaft can two-sided in axial sliding claw-type clutch, under the pressure of spring, clutch part engagement with sun gear, accept the drive torque that the center shaft transmission comes, realize the motion on the level land.When wheel is subjected to stopping of ladder,, cause sun gear not rotate because wheel is inactive, at this moment two-way claw-type clutch is under the effect of driving torque, be forced to break away from, thereby mesh, wheel carrier is overturn on ladder with the claw-type clutch that is fixed on the wheel carrier with sun gear.
This Climbing wheel can be widely used in the manpower push-and-pull vehicle, and polytype vehicles such as wheelchair, bicycle, motor bike, roadlice make vehicle can climb ladder again in the level land operation freely.But there is following defective in this Climbing wheel: 1. the planetary wheel formed of sun gear, idle pulley, planetary wheel is an exposed gear, is subject to external interference, influences the stability of Climbing wheel work; 2. power-transfer clutch is automatic conversion regime, complex structure, poor reliability; 3. clutch configuration is complicated and in pivoted arm inside, integral structure is not compact.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of star-wheel satellite gear reversible type to step on the building wheel, this planetary wheel of stepping on the building wheel is the enclosed gear, is not subjected to external interference, good stability.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of star-wheel satellite gear reversible type is stepped on the building wheel, and it comprises wheel carrier, the wheel with radial pivoted arm, and wheel is arranged on the end of each pivoted arm of wheel carrier; Wheel carrier is by a center shaft and body contact; Be provided with sun gear on center shaft, be respectively equipped with coaxial planetary wheel on the axle of each wheel, be respectively equipped with idle pulley between sun gear and each planetary wheel, sun gear and idle pulley are meshing with each other, and idle pulley and planetary wheel are meshing with each other; Wheel carrier is a casing, and sun gear, idle pulley, planetary wheel are arranged in the casing, and the axle of sun gear, the axle of idle pulley, planetary axle bearing are on casing, and wheel is arranged on the casing outside.
In the such scheme, step on the building wheel and also comprise power-transfer clutch; Center shaft is provided with spline or dive key; Power-transfer clutch comprises power-transfer clutch movable end that connects with center shaft splined or dive key and the power-transfer clutch fixed end of captiveing joint with wheel carrier.
In the such scheme, power-transfer clutch is denture clutch or tooth clutch.
In the such scheme, power-transfer clutch is arranged between casing and the vehicle body.
The utility model is stepped on the building wheel compared with prior art, has the following advantages:
1, wheel carrier is a casing, and the planetary gear train that sun gear, idle pulley, planetary wheel are formed is arranged in the casing, compact conformation, good stability.
2, be provided with power-transfer clutch between center shaft and the wheel carrier, simple in structure, good stability.Its principle of work is: when walking on the level land, power-transfer clutch movable end, fixed end separate, and total is a planetary gear structure, and sun gear is accepted the drive torque rotation that the center shaft transmission comes, turn a wheel thereby drive planetary wheel, realize the walking on the level land by idle pulley.When running into obstacles such as ladder, stirring the power-transfer clutch movable end slides at center shaft, make power-transfer clutch movable end, fixed end combination, locked center shaft of power-transfer clutch and wheel carrier, this moment, total was converted to star wheel structure, wheel carrier is accepted the drive torque rotation that the center shaft transmission comes, and whole wheel carrier and train of gears overturn to obstacles such as ladders.
3, power-transfer clutch is arranged between wheel carrier and the vehicle body, helps the control to power-transfer clutch, simultaneously, because power-transfer clutch is arranged on the outside of casing, can not influence the work of planetary gear train.
