Description
Technical field
The present invention relates to wheel design technical field, in particular to a kind of heavy vehicles new structure aluminum-alloy wheel.
Background technique
Lightweight is one of heavy vehicle, the important directions of wheeled battlebus, is energy-saving and emission-reduction, the main way for improving mobility
Diameter.And light metal material is used to replace steel, it is to realize light-weighted important means.Aluminium alloy is small with density, specific strength is high
And good workability, being that heavy vehicle, wheeled battlebus are light-weighted most preferably uses material.
Wheel is the rotary components that load is born between tire and axle, as heavy vehicle, the row of wheeled battlebus
Dynamic component, quantity is more in automobiles, and is all made of steel wheel at present.Such as certain wheeled battlebus, wheel is welded using Q235 steel fission
Manufacture is connect, bicycle is total to wheel-mounted 8, and single-piece wheel weighs nearly 60 kilograms, it is difficult to effective loss of weight.Therefore, novel aluminum alloy is studied
Wheel realizes that wheel, for steel, is of great significance with aluminium to mitigating vehicle weight and improving mobility.
Wheel is usually made of wheel rim and spoke two parts, sometimes also includes wheel hub.Wheel rim is installed and is propped up on wheel
The component of tire is held, machined surface profile can be divided into wheel rim, bcad seats, convex peak and groove portion；Spoke is on wheel between axle
Bearing part between wheel rim, structure are divided into mounting blocks part, buffering loop section and rim section.
On general-utility car, aluminum-alloy wheel is had been widely used.The reflectal wheel of Alcoa's production is
It is applied on motorbus, the country has also carried out forging and the application of aluminum alloy wheel of vehicle.But for heavy goods vehicles
, wheeled battlebus etc., due to compared with the higher carrying of general-utility car and cross-country condition, it is desirable that wheel has higher intensity and just
Degree.Such as a kind of aluminum alloy wheel for heavy-duty vehicle disclosed in patent ZL201110024751.3, propose aluminum-alloy wheel
Design and forming manufacturing method, promote the application of aluminum-alloy wheel on heavy vehicles.
Heavy vehicle, the wheel applied on wheeled battlebus at present, including aluminium alloy wheel rim 10, steel retaining ring 20 and retainer
30, gutter 40 is set on aluminium alloy wheel rim, and installation steel retaining ring 20 and retainer 30,30 both ends of retainer are supported respectively in gutter 40
Aluminium alloy wheel rim 10 and steel retaining ring 20 are fixed with this in firmly 40 edge of steel retaining ring 20 and gutter, refering to fig. 1, Fig. 2, Fig. 3；
Wherein, wheel rim uses aluminum alloy materials, and gear retainer uses steel material, and there are following main problems for discovery in use:
(1) steel gear retainer and aluminium alloy ontological existence dissimilar metal etching problem, and gutter root is due to lesser
Fillet is also easy to produce stress concentration, and slot is caused to crack and fail；
(2) installation for keeping off retainer is needed using dedicated equipment, and the replacement of tire or wheel rim is difficult to complete in use site
Replacement, increases use cost；
(3) steel gear retainer weight is big, and the effect of loss of weight to greatest extent is not achieved.
Summary of the invention
To solve the problems, such as that above-mentioned aluminum alloy wheel for heavy-duty vehicle gutter is easy to crack, dismounting is inconvenient, weight is big, this
Invention is designed to provide a kind of heavy vehicles new structure aluminum-alloy wheel, replaces conventional steel using aluminium alloy wheel rim
Retainer is kept off, and is connected through a screw thread detachable wheel rim and wheel rim, makes that the intensity of wheel is big, safety is good, light-weight, is had simultaneously
Good processing technology.
To achieve the goals above, technical scheme is as follows:
A kind of heavy vehicles new structure aluminum-alloy wheel, including aluminium alloy wheel rim and aluminium alloy wheel rim, aluminum alloy wheel
Edge is close to the side of aluminium alloy wheel rim installation tire, it is characterised in that: bulge loop, the bulge loop are equipped on the inside of the aluminium alloy wheel rim
Inside has internal screw thread, and the outer ledge of the aluminium alloy wheel rim is with the external screw thread of cooperation internal screw thread, the aluminium alloy wheel rim
It is connected through a screw thread removable loaded on the aluminium alloy wheel rim.
Further, it is described be threadedly coupled use saw-tooth thread, the left flank of tooth and the right flank of tooth of saw-tooth thread respectively with hang down
Angle is faced directly in 30 ° and 3 °.
Beneficial effects of the present invention:
(1) dissimilar metal corrosion and the gutter root fillet for avoiding steel gear retainer and aluminium alloy wheel rim are smaller
The stress being also easy to produce is concentrated, and fundamentally solves the problems, such as gutter Cracking Failure；The screw thread of aluminium alloy wheel rim and aluminium alloy wheel rim
Connection has good self-locking performance and operation convenience, and design uses zigzag (3 °, 30 °) screw thread, in use, 30 ° of angular direction
Sidespin closes, laborsaving convenience；Outside axial force is born in 3 ° of angular direction side, meets self-locking performance good condition.
(2) aluminium alloy wheel rim and aluminium alloy wheel rim are together by a threaded connection, and in use site, do not need special equipment
The replacement that tire or wheel rim can be completed improves ease of use, while reducing use cost.
(3) aluminium alloy wheel rim further mitigates wheel overall structure weight instead of steel retaining ring and retainer, obtains most
Limits weight loss effect.
Below in conjunction with drawings and the specific embodiments, the present invention will be further described.
