Abstract
The utility model relates to a fork crown including a crown body, a front fork middle pipe fixing hole is arranged in the middle part of the crown body, front fork branch pipe fixing holes are arranged in the crown body at the two sides of the front fork middle pipe fixing hole, and the fork crown is characterized in that the crown body is in a metal housing structure, and linings for installing front fork branch pipes through extrusion are welded in the front fork branch pipe fixing holes. The fork crown is advantageous in that the linings realize the connection manner of extruding and inserting the front fork branch pipes on the housing type crown body, so that the connection of the fork crown and the front fork can be more beautiful on the basis of guaranteeing the strength of the fork crown.
Description
Technical field
The utility model belongs to tricycle technical field, particularly relates to a kind of Front crown of tricycle.
Background technology
The kind of tricycle is varied, comprise road cycling, mountain bike, Electrical Bicycle and electro-tricycle etc., along with improving constantly and development and the maturation of vehicle technology of people's environmental consciousness, Electrical Bicycle, electro-tricycle have become the main traffic instrument of people's trip, and the functional stronger bicycles such as mountain bike and road cycling are more and more subject to liking of people.
Front fork is the primary member on tricycle, and front fork comprises in Front crown, front fork pipe and front fork arm, has for installing in the front fork of front fork pipe and manage fixed orifice on Front crown, and Front fork end covers to be had for front fork front fork by all means fixed orifice is by all means installed.In conventional art, the shoulder lid body of Front crown has two kinds, a kind of is forged aluminium structure, the end extruding of front fork arm is inserted into shoulder and covers in the front fork arm fixed orifice of body, this shoulder lid profile quality is high, attractive in appearance, forging cost is high, but the intensity of forged aluminium is low, and Forging Technology is complicated, forging cost is high; A kind of case type shoulder of making for metal sheet covers body, the end of front fork arm is welded on shoulder and covers in the front fork arm fixed orifice of body, and this shoulder lid intensity is high, but profile is coarse not attractive in appearance, in sum, be necessary to design a kind of good looking appearance and the high Front crown of intensity.
Summary of the invention
The utility model for solve the technical matters existing in known technology provide a kind of simple in structure, intensity is high, good looking appearance, the simple Front crown of processing and manufacturing.
The technical scheme that the utility model is taked for the technical matters existing in solution known technology is: a kind of Front crown, comprise that shoulder covers body, the middle part of described shoulder lid body has manages fixed orifice in front fork, on described shoulder lid body, being arranged in described front fork manages the both sides of fixed orifice and has front fork arm fixed orifice, it is characterized in that: described shoulder lid body is metallic shell structure, is welded with the lining of front fork arm being installed for pushing in described front fork arm fixed orifice.
The utility model can also adopt following technical scheme:
The lower end of described lining is provided with counterbore.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, in takeing on the front fork arm fixed orifice that covers body, case type installs lining additional, lining makes front fork arm extruding be plugged on the connection mode that case type shoulder covers on body and is achieved, with this, guaranteeing, on the basis of Front crown intensity, to make Front crown more attractive in appearance with being connected of front fork arm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, shoulder covers body; 1-1, front fork arm fixed orifice; In 1-2, front fork, manage fixed orifice; 2, lining.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of Front crown, comprise that shoulder covers body 1, the middle part that shoulder covers body 1 has manages fixed orifice 1-2 in front fork, being used for fixedly front fork manages, shoulder covers and on body 1, is arranged in front fork and manages the both sides of fixed orifice 1-2 and have front fork arm fixed orifice 1-1, and front fork arm fixed orifice 1-1 is used for installing front fork arm.Shoulder covers body 1 for metallic shell structure, is welded with the lining 2 of front fork arm being installed for pushing in front fork arm fixed orifice 1-1.Lining 2 adopts the mode of spot welding to be welded on the inside that shoulder covers body 1.Lining 2 makes front fork arm extruding be plugged on the connection mode that case type shoulder cover on body 1 and is achieved, and with this, on the basis of assurance Front crown intensity, makes Front crown more attractive in appearance with being connected of front fork arm.In the present embodiment, it is that irony shoulder covers body that shoulder covers body.
The lower end of lining is provided with counterbore, front fork arm is comprised of iron pipe and the corrosion-resistant steel sleeve pipe being sleeved on iron pipe, iron pipe extruding enters shoulder and covers in the front fork arm fixed orifice of body, between counterbore and iron pipe, be formed for the groove of plug-in mounting corrosion-resistant steel sleeve pipe upper end, thereby the corrosion-resistant steel sleeve pipe that makes to be sleeved on iron pipe outside and shoulder cover body closely, perfection is connected, avoid corrosion-resistant steel sleeve pipe and shoulder to cover between body and produce gap, improve overall appearance and the quality of front fork.
