Abstract
The utility model discloses a light car swing arm which comprises a V-shaped swing arm bracket, wherein two bushing holes and a ball pin shell fixing hole are formed in the swing arm bracket which is made of a steel plate, a vertical downward folding edge is formed at the side edge of the swing arm bracket, and the center of a main body of the swing arm bracket is sunken downward to form a groove. The swing arm disclosed by the utility model is formed in a way that the steel plate is punched, so that the self weight of a product is greatly reduced, the toughness is increased, the swing arm cannot be broken but can only be deformed in the event of an impact, and the safety of the whole car is improved; the folding edge is formed at the edge of the steel plate, so that the whole strength can be increased; the groove is formed in the center of the steel plate, a mounting hole which is matched with a car frame assembly is formed in the groove, and the mounting hole and the bushing holes as well as the ball pin hole are formed in two installation planes; when in use, torques are respectively borne, inner stress is dispersed, and the use strength is increased. According to the light car swing arm, the strength is guaranteed, additionally, the product weight is reduced, and the impact on a suspension system when the car is driven is reduced, thereby improving the car driving safety and reducing oil consumption.
Description
Technical field
The utility model relates to part of automobile engine and manufactures field, is specifically related to a kind of lightweight automobile swing arm.
Background technology
Passenger-car chassis suspension is divided into front suspension and rear suspension substantially, and forward and backward suspension has swing arm to connect wheel and vehicle body, and swing arm is usually located between wheel and vehicle body.Automobile swing arm is related to the performances such as damping property, walking stability and Steering sensitivity of automobile.Ironcasting manufacture is all used in existing swing arm, and its intensity is high, good reliability, but weight is larger, causes nonspring carried mass to become large, thereby has increased the impact load that suspension system is subject to, and the traveling comfort of car load is affected.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of lightweight automobile swing arm, adopts steel plate to substitute original ironcasting, sets up flanging and groove and guarantees working strength, greatly alleviates the weight of product, has improved toughness, has reduced oil consumption.
The utility model is achieved through the following technical solutions:
A kind of lightweight automobile swing arm, comprise " V " font oscillating arm bracket, oscillating arm bracket is provided with the fixed orifice of two bush hole and ball pin housing, described oscillating arm bracket is made by steel plate, the lateral edges of described oscillating arm bracket is provided with flanging straight down, and the main body mediad lower recess of described oscillating arm bracket forms groove.
The utility model further improvement project is, the sagging degree of depth of described groove is identical to the length of downward-extension with described flanging.
The utility model further improvement project is in described groove, to be provided with through hole some and that automobile chassis frame assembly is fixing.
The utility model compared with prior art has the following advantages:
Swing arm of the present utility model is by steel plate punched moulding, greatly alleviated the deadweight of product, improved toughness, when being subject to impacting, can not rupturing and only can be out of shape, improved the safety of car load, in edges of plate, be provided with flanging, can increase whole intensity, central authorities at steel plate establish groove, on groove, offer the mounting hole coordinating with chassis assembly, this mounting hole and bush hole, ball pin hole is positioned at two mounting planes, during use, bear separately moment of torsion, disperse internal stress, improve working strength, the utility model has reduced product weight in proof strength, the impact that while having reduced running car, suspension system is subject to, thereby improve the safety of driving, save oil consumption.
Accompanying drawing explanation
Fig. 1 is that the utility model is looked up structural representation.
The specific embodiment
A kind of lightweight automobile swing arm as shown in Figure 1, comprise " V " font oscillating arm bracket 1, oscillating arm bracket 1 is provided with the fixed orifice 3 of two bush hole 2 and ball pin housing, oscillating arm bracket 1 is made by zinc-plated black sheet, and the lateral edges of oscillating arm bracket 1 is provided with flanging 4 straight down, increases whole tensile strength, the main body mediad lower recess of oscillating arm bracket 1 forms groove 5, wherein, the sagging degree of depth of groove 5 is identical to the length of downward-extension with flanging 4, is convenient to assembling; In addition, in groove 5, be provided with through hole 6 some and that automobile chassis frame assembly is fixing, through hole 6 be installed and be positioned at two mounting planes with bush hole 2, ball pin housing fixed orifice 3, when stressed, can disperse internal stress, improve working strength.
