Problems solved by technology

At present, the traditional hand-operated tricycle adopts a ratchet mechanism, which can only realize one-way drive and a single transmission ratio. It takes a lot of circles to walk a short distance, and it is laborious to use; due to the use of a one-way drive system, its transmission ratio is fixed. The speed is fixed and cannot be accelerated; when it is necessary to climb a slope, because the traditional manual wheelchair adopts the traditional ratchet mechanism, it cannot prevent the wheelchair from slipping on the way up the slope. The traditional manual wheelchair has a single function and cannot meet the living needs of the disabled.

Embodiment Construction

[0009] Such as figure 1 and figure 2 As shown, a driving mechanism for a disabled vehicle, the driving system includes: an internal gear 1, a sun gear 2 and 3 planetary gears 3, the sun gear 2 is the center gear, and the 3 planetary gears are evenly distributed around the sun gear 2, The external teeth of the three planetary gears mesh with the internal teeth of the internal gear 1. The planetary gear 3 is installed on the small shaft 4 with a key. The small shaft 4 with a key can rotate counterclockwise. The sun gear 2 is the driving wheel and is connected with the driving handle. , the planetary gear train consisting of internal gear 1, sun gear 2, and 3 planetary gears is installed and fixed on the disc 5, and a wedge 6 is installed on the disc 5, and one end of the wedge 6 is fixed on the hub of the disc 5, The other end of the wedge 6 is pressed against the inner ring of the internal gear 1, the other end of the wedge 6 is connected with one end of the spring 7, and the...

Abstract

The invention discloses a vehicle driving mechanism for the disabled. The vehicle driving mechanism comprises a driving mechanism and a backward-rocking controlling and backward-moving preventing mechanism. The vehicle driving mechanism for the disabled is characterized by comprising a planetary gear train composed of an inner gear, a sun gear and a planetary gear. The planetary gear is installed on a one-way bearing, and the sun gear is a central gear. The backward-rocking controlling and backward-moving preventing mechanism is a disc, a wedge is arranged on the disc, and the disc is covered in an inner ring of the inner gear. The vehicle driving mechanism for the disabled overcomes the defect in a traditional driving mechanism that effort can not be saved, acceleration can not be conducted, and uphill climbing is not safe.

Description

technical field [0001] The present invention belongs to the technical field of drive systems. Background technique [0002] Hand tricycles are an important means of transportation for handicapped persons because of their inconvenience. More importantly, they use hand tricycles for physical exercise and participation in social activities. At present, the traditional hand-operated tricycle adopts a ratchet mechanism, which can only realize one-way drive and a single transmission ratio. It takes a lot of circles to walk a short distance, and it is laborious to use; due to the use of a one-way drive system, its transmission ratio is fixed. The speed is constant and cannot be accelerated; when it is necessary to climb a slope, because the traditional manual wheelchair adopts a traditional ratchet mechanism, it cannot prevent the wheelchair from slipping on the way up the slope. The traditional manual wheelchair has a single function and cannot meet the living needs of the disable...
