Description
Technical field
The utility model relates to the parts of automobile Mai Fuxun suspension, relates in particular to a kind of traveller assembly.
Background technology
The traveller assembly is the major part of McPherson suspension system, comprise parts such as spring, shock absorber, upper bracket and lower bracket, it links to each other with car body by upper bracket, links to each other with steering swivel by lower bracket, is mainly used on the front suspension system of the vehicle with self-supporting body.But the traveller assembly of using on present domestic all little cars, Rubber Parts in its upper bracket is not to sulfide with interior cover and overcoat, but be fitted between interior cover and the upper bracket by baffle plate, preload by Rubber Parts makes the three not have relative motion each other, rubber part bears the loading that car body weight causes and works the hinged effect that is beneficial to the shock absorber swing again because of promptly plaing, so the hardness of rubber can not be too little.Because rubber is ageing-resistant limited in one's ability, bearing the load that car body weight causes again, aging speed is accelerated, its volume is reduced, the preload of rubber is reduced even do not have, cause between Rubber Parts and its contacted parts and become flexible, cause traveller assembly early failure, cause front wheel alignment distortion and problems such as suspension abnormal sound even leakage of oil.
Summary of the invention
The purpose of this utility model is to provide a kind of traveller assembly at above-mentioned deficiency, and the Rubber Parts early failure causes problems such as front wheel alignment distortion and suspension abnormal sound in the upper bracket to solve.Its similar proportional structure is not limited to and is used for little car.
The technical solution of the utility model: the utility model traveller assembly comprises upper bracket assembly, shock absorber, be enclosed within spring on the shock absorber, with shock absorber lower end bonded assembly lower bracket, the shock absorber upper end is connected with the upper bracket assembly, and described upper bracket assembly comprises interior cover, overcoat, interlayer rubber coating, spacing chassis; In cover be flat straight tube bowl shaped structure, and the bottom through hole that has damper linking member to pass; Overcoat is carnival hat shape structure, and its internal diameter is greater than the external diameter of interior cover, and the through hole greater than interior cover diameter is arranged at the top; In the annular chamber in interlayer rubber is nested and is clipped between cover and the overcoat, and combine closely with interior cover and overcoat; Spacing chassis is a dish type, the outer rim on spacing chassis and the shade of overcoat coupling, the shade of spacing chassis and overcoat passes through bolted connection, there is following flange through hole the centre on spacing chassis, the flange of following flange through hole constitutes the back-up ring of bearing one side, and the opposite side back-up ring of bearing bottom is and the disk of bearing coupling that the through hole in the middle of the back-up ring also has downward flange, the hole coupling of this flange and spring top race, bearing is by the preload of spring and back-up ring applying up and down; Between cover top and the overcoat upper plenum is arranged in described, following cavity is arranged between bottom and the spacing chassis.
The height H 2 of the upper plenum in described between cover top and the overcoat is 3～15mm.
The height H 1 of the following cavity in described between cover bottom and the spacing chassis is 3～15mm.
Cover was to spacing chassis in stretched out the bottom of described interlayer rubber coating, and the sponson inboard is the conical ring of lower diameter greater than interior cover, forms down cavity with spacing chassis.
The top part of described interlayer rubber coating is stretched out interior cover, and the internal diameter of sponson forms upper plenum greater than the diameter of interior cover with overcoat.
Advantage of the present utility model: because the interlayer rubber coating only works the hinged effect that is beneficial to the shock absorber swing, do not bear the big load that car body weight causes, big load is to reach spring by overcoat, spacing chassis, bearing, bearing opposite side back-up ring, spring top race etc., reach steering swivel and wheel by shock absorber and lower bracket thereof again, as long as the interlayer rubber coating bears the so little load of absorber damping force, the hardness of rubber does not need too big like this; Rubber part and interior cover sulfuration simultaneously bonds together, directly sulfide with overcoat or by with the bonded assembly internal diameter interference fit of crossing metal transfer cover and overcoat of interlayer sulfuration, even the rubber existence is aging like this, itself and peripheral the bonding do not have relative motion between parts.The early failure of interlayer rubber coating has all been avoided in these measures, improves the life-span of traveller assembly.The utlity model has characteristics simple in structure, that the life-span is long.
