Abstract
The utility model discloses a novel bicycle chassis, which mainly comprises a five-through part and a hook jaw. Wherein: the five-through part is fixedly provided with an aluminium alloy sleeve tube; the aluminium alloy sleeve tube is fixed onto the five-through part via an interference fitting; aluminium alloy pasted sheets are fixedly provided respectively on both sides of the hook jaw; the hook jaw is fixedly provided on the aluminium alloy pasted sheet via screws; in actual use, an magnesium alloy five-through tube is embedded into the aluminium alloy sleeve tube rear via an 'interference' fitting, and then, welded, tapped and locked to couple with the bicycle middle shaft; actual contact with the middle shaft thread is fulfilled by the aluminium alloy sleeve tube thread, so that the five-through threads cannot be damaged because of corrosion; two aluminium alloy pasted sheets are applied on both sides of a left hook jaw and a right hook jaw on the magnesium alloy chassis, in order to effectively avoid potentiometric corrosion because of direct contact of the magnesium alloy hook jaws and a steel drum shaft and quick detachable nuts. Compared with the prior art, the utility model can effectively potentiometric corrosion that is created in connection and assembling of the magnesium alloy chassis with fittings made of steel, iron and etc, so as to overcome prior defects on magnesium alloy materials.
Description
Technical field
The utility model relates to a kind of bicycle accessories, refers in particular to a kind of new bicycle vehicle frame.
Background technology
In recent years, magnesium alloy materials is because of advantages such as its environmental protection, lightweight, the anti electromagnetic wave leaks is good, intensity is high, aboundresources, and is applied in " 3C " product and sports equipment aspect more and more.And for this whole world of the bicycle the most universal motion and the vehicle, it is with a long history that the application of magnesium alloy materials and research also can be described as, and will be following environmental protection and the lightweight product inexorable trend pursued.
But,, thereby make the application of magnesium alloy in the bicycle industry extremely tight bring many difficult problems for the safety performance requirement because the chemical and physical properties of magnesium alloy is active than other alloy; Its mainly be since this metallic element of magnesium at relative other iron and steel metal of occurring in nature, potential value is lower, behind the iron member direct contact, very easily forms the micro cell environment, under the situation that has electrolyte to exist, magnesium alloy will easily be corroded as anode.
Because the environment for use of bicycle is abominable (open air) relatively; situations such as collision are also unavoidable; especially stressed for the bicycle key, tooth line and rotation friction position; these protected modes obviously are not enough; in case protective cover is fallen by destroyed; then and very easily produce electrochemical corrosion between the iron member, can not play the effect of long-time protection.
The utility model content
The purpose of this utility model is to provide a kind of new bicycle frame, and it can overcome the defective that existing magnesium alloy material has, and can slow down the potential corrosion that the magnesium alloy vehicle frame produces when engaging assembling with accessory such as iron and steel effectively.
In order to achieve the above object, the technical scheme that the utility model adopted is: a kind of new bicycle vehicle frame, it mainly comprises five-way piece and colludes pawl, is installed with the aluminum alloy sleeve pipe in the described five-way piece in addition.
Described new bicycle vehicle frame, its aluminum alloy sleeve pipe cooperate by the interference mode with five-way piece and set firmly.
Described new bicycle vehicle frame, it colludes the pawl both sides and respectively is installed with the aluminum alloy paster.
Described new bicycle vehicle frame, it colludes pawl and the aluminum alloy paster sets firmly with screw.
After adopting said structure, during use, after the mode of magnesium alloy five-way pipe by " interference " embeds the aluminum alloy sleeve pipe, again through welding, tapping, join with bicycle middle shaft lock, actual contact axis tooth line be aluminum alloy sleeve pipe tooth line, can not destroy five-way tooth line because of corrosion; Collude the pawl both sides on limit, the magnesium alloy vehicle frame left and right sides, add two aluminum alloy pasters, can effectively avoid magnesium alloy to collude the flower-drum axle of pawl and steel and the potential corrosion that the Fast dismountable screw nut direct contact is produced; This is novel compares with commonly using, and the potential corrosion that it can slow down the generation when engaging assembling with accessory such as iron and steel of magnesium alloy vehicle frame effectively overcomes the defective that existing magnesium alloy material has.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Please refer to shown in Figure 1ly, the utility model discloses a kind of new bicycle vehicle frame, and it mainly comprises five-way piece 1 and collude pawl 2, wherein:
Be installed with aluminum alloy sleeve pipe 3 in addition in the described five-way piece 1, its aluminum alloy sleeve pipe 3 cooperates by the interference mode with five-way piece 1 and sets firmly.
After adopting said structure, during use, after magnesium alloy five-way pipe 1 mode by " interference " embeds aluminum alloy sleeve pipe 3, again through welding, tapping, join with bicycle middle shaft lock, actual contact axis tooth line be aluminum alloy sleeve pipe 3 tooth lines, can not destroy five-way tooth line because of corrosion; Collude pawl 2 both sides on limit, the magnesium alloy vehicle frame left and right sides, add two aluminum alloy pasters 4, can effectively avoid magnesium alloy to collude pawl 2 and the flower-drum axle of steel and the potential corrosion that the Fast dismountable screw nut direct contact is produced; This is novel compares with commonly using, and the potential corrosion that it can slow down the generation when engaging assembling with accessory such as iron and steel of magnesium alloy vehicle frame effectively overcomes the defective that existing magnesium alloy material has.
