Abstract
The utility model discloses a chassis rear suspension of an electric tricycle. The chassis rear suspension comprises a spring eye leaf spring, wherein, a chassis floating bridge is connected with the spring eye leaf spring in the middle through a U-shaped bolt and a pressing plate, the both ends of the spring eye leaf spring are respectively connected with a vehicle frame through a lifting lug, a bolt and a nylon sleeve, one end of the spring eye leaf spring adopts a spring eye type, the other end of the spring eye leaf spring adopts a freely stretching type, and the nylon sleeve is installed at one end of a spring eye of the spring eye leaf spring. The chassis frame is designed into a floating bridge type structure, the rear suspension is a spring eye leaf spring structure, the bridge framework is accurately welded by fine steels to form a floating connection state with the complete vehicle, so that the complete vehicle plays the roles of shock-absorption and balancing during the steering process and when the road surface is uneven, the stability of driving of the complete vehicle is enhanced, and the vibration and the noise can be effectively eliminated; the spring eye leaf spring has stronger bearing capacity and has good shock-absorption effect and low noise; the riding is comfortable, and the safety performance is reliable; and the utility model is simple and reasonable and has high structural strength.
Description
Technical field
The utility model relates to a kind of electric three-wheel chassis rear linkage.
Background technology
Present electric three-wheel chassis rear overhang is hung and mostly is simple leaf spring damping connection, and the direct use hinge that has connects.These rear-mounted structures exist damping effect bad more, easily produce noise, and structural strength is not high, takes defectives such as uncomfortable, poor safety performance.
Summary of the invention
The utility model provides a kind of electric three-wheel chassis rear overhang to hang, and it is stable that this back hangs switching performance, and damping effect is good, and noise is low.
The purpose of this utility model is achieved in that this chassis rear overhang satchel draws together the grasswort steel spring, the unsteady crane span structure in chassis links to each other with pressing plate and grasswort steel spring centre by U-bolt, grasswort steel spring two ends link to each other with vehicle frame by hanger, bolt, nylon jacket respectively, grasswort steel spring one end is the grasswort formula, the other end is free telescopic, in grasswort one end of grasswort steel spring nylon jacket is housed.
The utility model is designed to the floating axle rack and panel construction with sole, the back hangs and is grasswort steel spring structure, adopt high-quality shaped steel accurately to be welded into the crane span structure skeleton, form unsteady coupled condition with car load, make car load when turning to, play the favorable damping equilibrium activity with Uneven road, improve the stability that car load travels, can eliminate vibrations and noise by actv..The grasswort steel spring has stronger load-carrying capacity, and damping effect is good, and noise is low.Ride comfort, safety performance is reliable.Advantages of simple, the structural strength height.
