Abstract
The utility model discloses a tricycle front fork form and a fixing structure which comprise a front fork frame and a front fork shaft housing; the front fork shaft housing is fixed at the front end of the tricycle frame; and the tricycle front fork form and the fixing structure is characterized in that the front rake angle of the front fork shaft housing is from 30 to 45 degrees; the front fork presents the backwards bending shape; and the bending degree is 165 degrees. a novel form and a fixing structure are adopted by the utility model, the centrifugal force of the center of gravity of vehicles can withstand, so as not to lead the vehicles not to be easily side-overturned.
Description
Technical field
This reality novel three-wheel vehicle that relates to, especially three-wheel vehicle fork.
Background technology
Present three-wheel vehicle as three wheeled motor vehicle, agricultural tricycle, three-wheeled electric vehicle, motor-tricycle etc., all is that three wheels are arranged, the front-wheel that there is the load-bearing of a wheel front and is responsible for turning to.Front-wheel is installed on the front forked frame, preceding fork frame is installed in the preceding fork axle sleeve and on a center of turn, preceding fork axle sleeve is fixed on the vehicle frame front end and is FC, forward leaning angle (angle of axle sleeve axial line and perpendicular line) is 15-25 °, preceding fork frame is straight shape (as shown in Figure 1), makes front-wheel stretch out certain distance to oblique below and is convenient to steering operation.The deficiency of this form structure is when three-wheel vehicle is turned, and lack of equilibrium outwards rollover easily causes roll-over accident under car weight heart action of centrifugal force power.
Summary of the invention
For solving three-wheel vehicle turning rollover problem, the utility model proposes a kind of new preceding fork form and fixed sturcture.
Fork form and mounting structure before a kind of three-wheel vehicle, fork frame and preceding fork axle sleeve before it comprises, preceding fork axle sleeve is fixed on the tricycle frame front end, it is characterized in that, and the front rake of preceding fork axle sleeve is 30-45 °, and preceding fork is bending backward, and angle of bend is 165 °.That is to say that preceding fork cover has increased by 15 ° front rake than existing structure, preceding fork frame has reduced 15 ° backward than existing shape and has been bended.
Take this new form and the good effect of fixed sturcture to be: when steering dish (or handlebar) when turning to, the touchdown point of front-wheel is side shifting outside turning, with outside rear wheel on a driving trace.Can keep out the centnifugal force of vehicle's center of gravity like this, vehicle can not turned on one's side easily.
Description of drawings
Fig. 1 is existing preceding fork form and fixed sturcture scheme drawing.
Fig. 2 is the form structure scheme drawing of the utility model embodiment.
When Fig. 3 is Vehicular turn, the scheme drawing of three wheel acting point.
Marginal data: fork frame before the fork axle sleeve before the 1-vehicle frame, 2-, 3-, 4-front-wheel, 5-trailing wheel.
The specific embodiment
As shown in Figure 2, fork frame 3 and preceding fork axle sleeve 2 before the utility model comprises, preceding fork axle sleeve 2 is fixed on tricycle frame 1 front end, it is characterized in that, and the front rake α of preceding fork axle sleeve 2=30-45 °, preceding fork frame 3 is bended backward, warpage angle beta=165 °.
As can be seen from Figure 2, when steering dish (or handlebar) when turning to, the touchdown point of front-wheel 4 is side shifting outside turning, with outside rear wheel 5 on a driving trace.
Claims (1)
1, fork form and fixed sturcture before a kind of three-wheel vehicle, fork frame and preceding fork axle sleeve before it comprises, preceding fork axle sleeve is fixed on the tricycle frame front end, it is characterized in that, the front rake of preceding fork axle sleeve is 30-45 °, and preceding fork is bending backward, and angle of bend is 165 °.
