Abstract
The invention discloses a pivot turning structure suitable for a small vehicle in a narrow space, which comprises a telescopic cylinder fixedly connected to the bottom of a vehicle chassis, wherein the telescopic end of the telescopic cylinder is rotatably connected with a supporting plate, the fixed end of the telescopic cylinder is fixedly connected with a driven gear, the driven gear is meshed with a driving gear, the driving gear is connected to an output shaft of a motor, the motor is fixedly connected to the bottom of the engineering vehicle chassis, and the motor drives the driven gear to rotate through the driving gear, so that the vehicle is driven to rotate relative to the supporting plate. The invention can realize the in-situ turning of the vehicle and is very suitable for the operations of turning, turning around and the like of small vehicles in a narrow space.
Description
Technical Field
The invention relates to the technical field of engineering vehicle structures, in particular to a small vehicle in-situ turning structure suitable for a narrow space.
Background
In conventional wheelchairs, the hub portion is larger and equipped with braking and like systems, but there are major difficulties if pivot turning is to be achieved. The wheelchair is clumsy to move and limited to move in a narrow space when the wheelchair cannot turn in place, meanwhile, the wheelchair is gradually replaced by an automobile and the like along with the traveling mode of people, but the wheelchair is difficult to turn and turn around when the wheelchair travels through a narrow section, so that the wheelchair has requirements on the capability of a driver and provides new thinking for the improvement of the structure of the wheelchair.
Disclosure of Invention
The invention aims to solve the problem that the existing vehicles such as wheelchairs and the like are inconvenient to move, and provides a structure capable of realizing in-situ turning of the vehicles in a narrow space.
In order to solve the problems, the invention adopts the following technical scheme:
the utility model provides a small-size vehicle pivot turn structure in being applicable to narrow and small space, includes the telescoping cylinder of fixed connection in vehicle chassis bottom, and the flexible end of telescoping cylinder rotates and is connected with the supporting disk, and the stiff end of telescoping cylinder has linked firmly driven gear, driven gear and driving gear meshing, and the driving gear is connected on the output shaft of motor, and motor fixed connection is in engineering vehicle chassis bottom, and the motor passes through the driving gear and drives driven gear and rotate to drive the relative supporting disk rotation of vehicle.
The motor rotates to drive the driving gear to rotate, the driving gear drives the driven gear to rotate, and the telescopic cylinder is connected with the supporting disk in a rotating mode and fixedly connected with the chassis as the driven gear is fixedly connected to the telescopic cylinder, so that the telescopic cylinder and the vehicle above the supporting disk are driven to integrally rotate, and in-situ turning is achieved.
Preferably, the telescopic cylinder is a hydraulic cylinder and is arranged in the center of the chassis, so that the stress of the telescopic cylinder is balanced, and the vehicle is stable and does not shake in the rotating process.
Preferably, the supporting disk is circular steel plate structure, and the supporting disk bottom surface is provided with the slipmat, and the supporting disk supports subaerial, supports the weight of vehicle, and the lifting surface area will be big, and supports and need increase the frictional force with ground on subaerial and carry out the antiskid.
Preferably, the telescopic end of the telescopic cylinder is rotatably connected with the supporting disc through a pressure bearing. The supporting disc and the telescopic cylinder can support the weight of the whole vehicle to complete rotation.
The invention has the beneficial effects that:
the invention can realize the in-situ turning of the vehicle and is very suitable for the operations of turning, turning around and the like of small vehicles in a narrow space.
