Description
Technical field
The present invention relates to the resilient suspension of the feature that is arranged as of spring and damper combination, especially a kind of caravan independent suspension.
Background technology
We know, suspension is the general name of all force transmission connections between the vehicle frame of vehicle and vehicle bridge or wheel, its effect transmits the power that acts between wheel and vehicle frame and power is turned round, and buffering is passed to the impulsive force of vehicle frame or vehicle body by uneven road surface, and the vibrations caused thus that decay, to ensure that vehicle can smoothly travel.
Along with growth in the living standard, the preferred manner that out on tours becomes leisure in people vacation, loosens, caravan has " room " and " car " two tourism supplies of large function concurrently as one, is subject to people and favors.Caravan trailer is the afterbody hung together by caravan at tractor truck, and the one utilizing tractor truck to tow leisure vehicle, its suspension adopted on caravan is then the critical component affecting caravan rideability.At present, existing caravan suspension generally comprises two wheels, an axis and two steel springs, and two wheels are rotatably supported in the two ends of axis respectively, and steel spring is fixedly connected between axis and vehicle frame by anchor ear.When caravan travels on road surface, the vibrations produced by wheel cushion through steel spring, and vehicle frame keeps relatively steady.Because two vehicle wheel rotations are supported on the two ends of same axis, when caravan jolt road surface travels time, the surface conditions of two wheels contacts is different, very easily mutually interferes, causes car body to produce comparatively big bang; In addition, above-mentioned suspension frame structure is the dependent suspension structure that two wheels connect same axis, and caravan is when running at high speed, and its ride comfort is poor; Meanwhile, its steel spring be fixedly connected between axis and vehicle frame, causes its ground Clearance too low (≤200mm), makes caravan be not suitable for cross-country application.
Summary of the invention
In order to overcome existing caravan suspension adopt axis and steel spring buffer structure to exist car body shakes greatly, riding comfort is poor, the ground Clearance too low deficiency being not suitable for cross-country application, the invention provides that a kind of structure is simple, the ground Clearance is high, use is reliable, good damping effect, caravan travel smooth-going caravan independent suspension.
The technical solution adopted for the present invention to solve the technical problems is: a kind of caravan independent suspension, it comprises a semiaxis, it is characterized in that: it also comprises a transverse arm, a trailing arm, a spring and at least one liquid damper, described semiaxis is fixedly connected on described transverse arm, one end of described trailing arm is fixedly connected with described transverse arm, the other end is fixedly connected with lateral connection cover, and this lateral connection cover is hinged on the free bearing of caravan vehicle frame; Described transverse arm is provided with at least one lower free bearing, on caravan vehicle frame correspondence be provided with at least one on free bearing, the two ends of described liquid damper are hinged on described upper free bearing, lower hinge Cuo respectively; Described trailing arm is provided with a spring lower support, and on caravan vehicle frame, correspondence is provided with a upper bracket of the spring, and the two ends of described spring are assemblied in described upper bracket of the spring, spring lower support respectively.
Described upper bracket of the spring, spring lower support are made up of the base plate be fixedly connected with caravan vehicle frame, trailing arm respectively and the back-up ring be fixed on base plate.
Cushion rubber is respectively equipped with between the two ends of described spring and upper bracket of the spring, spring lower support.
Described trailing arm is the first longeron and the second longeron composition, the first described longeron and one end of the second longeron are that angular structure is fixed on described transverse arm, and described lateral connection overlaps coaxial line respectively and is fixedly connected on the other end of the first described longeron, the second longeron.
Deep beam is fixedly connected with between the first described longeron and the second longeron.
Described liquid damper is two.
One end of trailing arm is fixedly connected with transverse arm by the present invention, and the other end is fixedly connected with lateral connection cover, and this lateral connection cover is hinged on the free bearing of caravan vehicle frame; Semiaxis is fixedly connected on transverse arm, the two ends of liquid damper are hingedly connected on transverse arm and caravan vehicle frame respectively, trailing arm is provided with a spring lower support, and on caravan vehicle frame, correspondence is provided with a upper bracket of the spring, and the two ends of spring are assemblied in upper bracket of the spring, spring lower support respectively.Structure of the present invention is simple, use is reliable; Compared to conventional axis, the present invention adopts two semiaxis, is independently arranged on vehicle frame both sides, does not mutually interfere, and its good damping effect, caravan travel smooth-going.The structure adopting spring and hydraulic damper to combine, makes the vehicle frame ground Clearance reach 280mm, surmounts the tractor truck ground Clearance, greatly improves road by performance, and adapts to rigors such as paddling, cross-country.
