Trailing-Arm also translated trailing arm type, is designed for a rear wheel suspension system designed to bind the arm portion of the vehicle body front axle shaft and the axle, wherein the body portion of the spindle rotation axis is perpendicular to the centerline of the vehicle body by , i.e. straight rear, trailing arm or full called trailing arm type.
1. Noun interpretation trailing arm
Trailing-Arm also translated trailing arm type, it is designed for a rear wheel suspension system designed to bind the arm portion of the vehicle body in front of the axle spindle and the axle, wherein the body portion of the spindle rotation axis is perpendicular to the centerline of the vehicle body by, i.e. straight rear, trailing arm or full called trailing arm type.
2. The basic structure of the trailing arm type
Trailing-Arm also translated trailing arm type, is designed for a rear wheel suspension system designed to bind the arm portion of the vehicle body front axle shaft and the axle, wherein the body a rotating shaft perpendicular to the spindle body’s center line, i.e. vertical rear, trailing arm or full called trailing arm type, the use of such systems in vehicles like cars PEUGEOT (Peugeot cars), CITROEN cars (Citroen cars), the OPEL cars (Opel models) or the like, semi-trailing arm and the swing arm to the vehicle body center line that is inclined lines obliquely rearward.
The trailing arm type suspension structure as the main body portion is bonded directly to the vehicle body, the spindle is then bound to the suspension system, then this member is attached to the vehicle body, the spring and the shock absorbers are usually mounted separately or It is integral, in the vicinity of an axle mounted upright. Movement of the suspension system itself, the arm of the vehicle body centerline perpendicular to the axis, i.e. parallel to the axis of motion of the center axle, the axle is not inclined to the vehicle body, a vertical movement in any position, parallel to the axle of the vehicle body, the inclination of the outer body change is zero. Which is the biggest advantage is that a large space of about two, but no change in the camber angle of the vehicle body, the shock bending stress does not occur, so that the friction is small, except when it is the front brakes will be heavier sinking, trailing arm the rear suspension also sank balance the body, but the drawback is unable to provide precise geometry control.
3. Trailing arm type characteristics
The trailing arm suspension itself has the disadvantage of non-independent suspension, but also combines the advantages of an independent suspension, the trailing arm suspension biggest advantage is a large space of about two, but no change in the camber angle of the vehicle body, shock bending stress does not occur, the friction is small. This suspension comfort and handling are limited, when it is in addition to the front brakes to be heavier outer sink, trailing arm rear suspension also balanced sinking body, can not provide precise geometry control.
In the trailing arm type suspension design process, different beam longitudinal arm in the mounted position of the performance thereof manifested very large, if the cross member is mounted closer to the trailing arm and the vehicle body connecting point (FIG. place with three bolts), the comfort of the car will be better but will roll when cornering bigger. If the beam is mounted closer to the trailing arm close to the wheel center, comfortable performance will be greatly reduced, it is manifested by a characteristic of the carrier and oriented. We are closer to the overall design of the bridge. With domestic trailing arm suspension are: Dongfeng Peugeot 206, Guangzhou Honda Fit, Toyota Corolla FAW, Shanghai Volkswagen Santana.
4. Disadvantages trailing arm
The trailing arm suspension system is designed specifically for a rear wheel suspension system, like cars Peugeot , Citroen cars, Opel cars and other cars in Europe prefer using this suspension system. The biggest advantage of trailing arm suspension system is larger space of about two, but no change in camber angle of the vehicle body,Shock bending stress does not occur, the friction is small, good seating quality, in addition to the front when it is heavy braking will sink to the outer, rear trailing arm suspension will balance sinking body, but the drawback is not provide precise control of geometry, but if properly tuned, with a minimum of cost and space to achieve the best results, it is now a multi-car rear suspension using this form.
