Abstract
The utility model provides a front fork of a two-wheel car. The front fork comprises a left fork leg, a right fork leg, a shoulder box, a direction column and a supporting plate. The direction column is connected above the shoulder box. Two supporting points are arranged on corresponding positions on the upper end portions of the left fork leg and the right fork leg respectively. One corresponding supporting point is connected with the shoulder box. The other corresponding supporting point is connected with the supporting plate. A damper is arranged between the top portion of the shoulder box and the supporting plate. The front fork has the advantages that the stress damping direction of a front fork part of a bicycle or an electric car is changed, stress is even, damping effect is good, the left fork leg and the right fork leg are of a metal plate structure, attractiveness and elegance are achieved, and a triangle structure is good in strength. A vertical pipe of a traditional front fork is changed, the stress angle of the vertical pipe is small, strength is good, and safety of a product is increased. The damper is arranged above the front fork, damping softness and damping hardness are convenient to adjust, meanwhile maintaining and replacing are convenient, and accordingly the whole damping performance of the front fork is adjusted.
Description
Technical field
The utility model relates to bicycle and vehicle technology field, relates in particular to a kind of front fork of cart.
Background technology
The front fork parts are in position, the place ahead in cart structures such as bicycle or battery-driven car, its upper end links to each other with the handlebar parts, and frame part cooperates with preceding pipe, and the lower end cooperates with preceding spindle unit, form the guidance system of bicycle.
In the prior art, front fork structure comprises left fork leg, right fork leg, pitches and take on and the direction post, and the fork shoulder connects left leg and the right fork leg pitched, and the direction post is arranged on to pitch and takes on, and leg is pitched in a tubular form in left side fork leg and the right side, and its inside is equipped with bumper.The stressed damping of this shock-damping structure is inhomogeneous, and damping effect is not good enough, and bumper is arranged in the left side fork leg and right fork leg of tubulose the maintain and replace inconvenience.
The utility model content
At the problems referred to above, problem to be solved in the utility model provides a kind of front fork of cart.
The technical solution of the utility model is as follows:
A kind of front fork of cart, comprise left side fork leg, right fork leg, shoulder box, direction post and stay bearing plate, described shoulder box top closure post, be respectively equipped with two fulcrums on the upper end correspondence position of described left side fork leg and right fork leg, a corresponding fulcrum connects the shoulder box, another corresponding fulcrum connects stay bearing plate, connects the adjustable bumper of damping soft or hard between the top of described shoulder box and the stay bearing plate.
Further, the fulcrum of two fulcrums of described left side fork leg or right fork leg upper end and bottom constitutes triangular structure.
Further, described stay bearing plate comprises left stay bearing plate and right stay bearing plate, and left stay bearing plate one end connects left side fork leg, and the other end connects bumper; Right stay bearing plate one end connects right fork leg, and the other end connects bumper.
Further, the cross section of described stay bearing plate takes the shape of the letter U.
Further, the outside of described bumper is provided with trim.
Further, described left side fork leg or right fork leg are provided with lock-bit.
Further, described left side fork leg and right fork leg are metal plate structure.
Because adopt technique scheme, the beneficial effects of the utility model are:
1. changed the direction of the stressed damping of front fork parts of bicycle or battery-driven car, stressed even, damping effect is better;
2. left side fork leg and right fork leg adopt this metal plate structure, and the three-legged structure intensity that two fulcrums of upper end and the fulcrum of bottom constitute is better, and elegant in appearance.
3. change the vertical tube of traditional front fork, make the vertical tube loading angle littler, intensity better increases Product Safety.
4. bumper is arranged on the front fork top, and be convenient to the damping soft or hard and regulate, convenient for maintaining and replacing simultaneously, thus adjust the whole damping performance of front fork.
5. integral structure designs according to lever principle, improves the bumper damping effect.
