Abstract
The invention discloses a wheelchair convenient for stair climbing and suburb cross-country, which belongs to the technical field of wheelchairs and mainly comprises wheels, a swing frame, a converter, a wheel groove frame, a suspension frame, a seat and the like. The four-wheel wheelchair with the large wheelbase and the small wheelbase at the two sides has more advantages in climbing stairs and cross-country than a wheelchair with the same wheelbase. The wheelchair avoids the up-and-down jolting in the front and back directions when climbing stairs, when each single wheel is lifted, one side of the wheelchair is lifted by 1/2 of the single wheel, when the front two wheels are lifted, the single wheel bearing weight is less than the whole mass 1/4, and when the rear two wheels are lifted, the single wheel bearing weight is slightly more than the whole mass 1/4. The wheelchair with the structure does not jolt when going upstairs or downstairs, only slightly fluctuates left and right, and the wheels are light, convenient, fast and labor-saving when climbing stairs.
Description
Technical field
The present invention relates to wheelchair technical field, more specifically a kind of it is easy to the cross-country wheelchair of stair climbing and countryside.
Background technology

Two wheels of wheelspan and the right wheelspan different, left and right two axle sleeves are all installed with wheel truss, wheel truss are arranged
There is mobile race, be fitted with two movable pulleys in left and right two mobile races, movable pulley is provided with moving shaft, same
A type hanger bracket is provided with two moving shafts of side, the top of A type hanger bracket is provided with suspension short axle, left and right two suspensions
It is hung with seat between short axle, seat is provided with rocking rod controller.
Described a kind of be easy to the cross-country wheelchair of stair climbing and countryside it is characterised in that：Described transducer is by tooth shell
Body, conversion gear axle, semiaxis, half axle gear and conversion tooth composition, the left and right two ends of tooth housing are fitted with semiaxis, and semiaxis is located at tooth
Part in housing is provided with half axle gear, and tooth housing is provided with conversion gear axle, and the two ends of conversion gear axle are fitted with turning
Change tooth.
It is an advantage of the current invention that：
The both sides wheel base that the present invention the provides big four-wheel wheelchair little on one side wheelchair equally bigger than wheelspan on one side, is climbing
Building and cross-country going up have more superiority.It avoids pitching in front and back when climbing building, and when each single-wheel raises, wheelchair one
It is the 1/2 of single-wheel rising that side raises, and is less than whole quality 1/4 by single-wheel again, rear two-wheeled single-wheel is omited again when front two-wheeled raises
More than whole quality 1/4.Do not jolt during the wheelchair stair activity of this spline structure, only can slightly fluctuate left and right, wheel stair climbing is light
Just convenient power-saving.
