Description
Technical field
The present invention relates to motorcycle steerage gear, what be specifically related to is a kind of steering hardware for handling front wheel of motor tricycle.
Background technology
The steering unit for front wheels of current motor-tricycle comprises handlebar, steering column, up and down yoke plate, left fork leg and right fork leg.Handlebar is arranged on upper connective plate, steering column and lower linking plate weld together, left fork leg and right fork leg are coupled together by lower linking plate, when handlebar rotates around steering column, upper and lower yoke plate rotates thereupon, and drives front-drive by left fork leg and right fork leg, and this steering hardware comes with some shortcomings part, as, the rotational angle of front-wheel is subject to certain restrictions; Needing large rotation angle handlebar when turning to, just can make front-wheel steering, and need the strength that expense is very large when turning to, repair cumbersome simultaneously.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide a kind of easy to operate, time saving and energy saving, front wheel of motor tricycle steering hardware easy to maintenance.
Steering hardware for handling front wheel of motor tricycle of the present invention, comprises front fork, and front fork comprises two parallel left fork legs and right fork leg, and by base plate that left fork leg is connected with right fork leg; Steering column, the first end of steering column is connected with bearing circle.Base plate is provided with gravity load bearing component, power load bearing component is provided with gear case, gear case inside is provided with D shape ring gear, external gear and rotating shaft, D shape ring gear and external gear are arranged in gear case by supporter, rotating shaft is connected with D shape ring gear, the inner side of D shape ring gear is provided with cavern part, cavern part takes the shape of the letter U, the inside face of D shape ring gear arch section is provided with the intermeshing tooth with external gear, external gear is located in cavern part, and engage each other with the tooth of D shape ring gear, external gear is connected with the second end of steering column, wherein said D shape ring gear is around the central rotation of described external gear, described steering column rotates and drives described external gear to rotate, described external gear drives described D shape ring gear to rotate, described D shape ring gear drives described axis of rotation.
Have such scheme visible, the base plate for the steering hardware handling front wheel of motor tricycle is provided with gravity load bearing component, can increase the load-carrying capacity of motor-tricycle.Power passes to rotating shaft by inner engagement of external gear and D shape ring gear, rotating shaft controls left fork leg again and right fork leg turns to, thus controls turning to of front-wheel, and the transmitting ratio of D shape ring gear and external gear is greater than 1, therefore the steering angle of front-wheel can increase, and decreases strength when turning to simultaneously.
Preferred version is gravity load bearing component is thrust ball bearing.Because thrust ball bearing can carry gravity, further increase the load-carrying capacity of motor-tricycle.
Preferred version is that to hold supporter be deep groove ball bearing.Due to zanjon bearing, to have friction coefficient little, good sealing effect, can carry the feature of radial and axial load, makes D shape ring gear like this and has less friction force between external gear and zanjon bearing, can prevent dust from entering bearing, the effect of fixing D shape ring gear and external gear simultaneously.
A preferred version is the axis of symmetry position being centrally located at cavern part of external gear.D shape ring gear along the central rotation of external gear, therefore, can control the symmetrical rotation of rotary steerable D shape ring gear of external gear, thus controls the symmetrical rotation of front-wheel.
A preferred version is that external gear center is provided with centre hole, and the second end of steering column is connected with external gear interference through centre hole.Such steering column and external gear Assembly &Disassembly conveniently, are convenient to maintenance.
A preferred version is that D shape tooth Ring current distribution is provided with axis hole, is provided with keyway in axis hole, and rotating shaft is connected with D shape ring gear key through axis hole.Such rotating shaft and D shape ring gear Assembly &Disassembly conveniently, are convenient to maintenance.
A preferred version is that D shape ring gear compares for 1-10 with external gear driving.Because D shape ring gear and external gear driving ratio are greater than 1, when change turns to, required power is less.
Further scheme is D shape ring gear is 65/12=5.42 with external gear driving ratio.Because D shape ring gear and external gear driving are comparatively large frequently, turn to light, dial rotation radian is little.
Comprehensive such scheme is visible, and power of the present invention is by transmitting in D shape ring gear and engaging each other of external gear, and D shape ring gear is greater than 1 with external gear driving ratio.When controlling the rotation of steering column, steering column drives external gear to rotate, external gear drives D shape ring gear to rotate, thus drive axis of rotation, front-wheel receives the turning effort of rotating shaft and rotates, and therefore can achieve the present invention easy to operate, time saving and energy saving object, D shape ring gear and external gear are arranged in gear case by supporter simultaneously, easy to installation and maintenance.
