Vehicle suspension
The vehicle suspension provides an elastic connection a carrier system (frame, body) with the wheels of the car. To suspensions of the car have the following requirements: • ensuring smooth running; • provision of movement on the road without UDA- ditch the limiter; • limit lateral roll of the vehicle; • harmonization of the movement of the steered wheels; • ensuring the decay of the body and wheels; • the permanence of a track, angles of the wheels; • reliable transfer from the wheels to the body longitudinal and transverse forces. The nature of the interaction of the wheels and the body in motion research all the car suspensions are divided into dependent and independ- independent. Front suspension has a rigid connection between wheels- Noah pair, resulting in movement of one of the wheels in transverse plane of the vehicle is transferred to another and cause roll of the vehicle. Independent suspension is characterized by the absence- tough connection between the wheels of one axle (axis), each co- timber suspended to the frame (body) independently of the other. In the result of hitting one wheel on uneven road leaf transverse displacement it is not passed on to others- th wheel, thereby reducing the possibility of inclination of the body and increases overall vehicle stability when motion. Dependent (independent) suspension is used for two- axle vehicles and buses, it is rare for passenger cars- mobiles. Dependent (balanced) suspension used Ute suspension for two closely spaced mos tov, for example, three-axle vehicles. When installing pneumatic and hydraulic machined parts- the juice are created the conditions for the possibility of controlling you- honeycomb floor or ground clearance. Combined under- Veski consist of primary and secondary elements for adjustment of the elastic characteristics. For example, Lis- tovo spring and springs, rubber or pneumatic additional items. In the most General case the suspension consists of: • an elastic element, which are used: IU- metal leaf springs; cylindrical springs; rods, working in torsion (tor- the Sion) or non-metallic elements, provide- ing the suspension elasticity of the rubber, JUA- the air or fluid; combined elastic- many of the elements consisting of metal and NEMA- metal materials; • the guide device for providing a transceiver Chu pushing, braking and lateral forces from the wheels the frame (body) of the car. When spring suspension- ke — levers and rods; spring — itself- stowa spring; • dampening element is designed for damping the amplitude of the oscillations of the body and the wheels when hitting road irregularities, for this purpose at the auto carts used liquid dampers. Device dependent suspension. As elastic elements are used for longitudinal semi-elliptic leaf springs, working in conjunction with the guide- replicase dampers. Spring front suspension consists of a package of steel elastic sheets of various lengths, fastened between the clamps and attached to front beam bridge ladders. To the longeron ends indigenous the sheet is attached by means of brackets with rubber pillows. To facilitate vertical suspension stroke the front end of the spring fixed in the bracket and ass- in the end of the spring has the ability to mix with her the longitudinal deflections in rubber cushion bracket. Spring rear suspension is attached to longer- well frames differently than the front. The front end of spring ball Nino through the finger connected to the frame. Such a connection provide enables transmission of longitudinal force when driving a car- mobile. The rear end of the spring moves freely in the longitudinal direction between the breadcrumbs bracket when the deflection of the spring. On top of the main spring tends- mankame fixed additional spring, the ends of which Roy is located near the support brackets. In loaded- Mr. able further the ends of the springs rest against brackets main spring, and together they carry the load on the car. Without the extra load the springs not RA- pay. On cars with spring suspension to- additional springs are not used. |
