Abstract
The utility model discloses a rubber sleeve upper cross arm, which includes an upper cross arm shaft 8, an upper cross arm 3 and a welding sleeve 2. The welding sleeve 2 is welded on the upper cross arm 3. The utility model is characterized in that each side of the upper cross arm 3 has double arms; the welding sleeve 2 and the outer cover 4 of the outside of a rubber sleeve 5 adopt an interference fit; the upper cross arm shaft 8 and an inner sleeve 6 of the inside of the rubber sleeve5 adopt a clearance fit; the rubber sleeve 5, the inner sleeve 6 and an outer sleeve 4 are vulcanized together; and the end head of the upper cross arm shaft 8 is locked with the inner sleeve 6 by a locknut 1. The utility model has the advantages that the structure is novel, the processing technique is excellent, the service life is long, lubricant adding is unnecessary, the installation is convenient and the maintenance is easy.
Description
The utility model relates to a kind of gum cover formula Top Crossbeam, and it is mainly used in the IFS Independent Front Suspension bridge of automobile.
Disclosed screw connected Top Crossbeam in the prior art, mainly constitute by Top Crossbeam axle, Top Crossbeam, swivel nut, welding silk braid, lubricating cup and seal rubber sleeve, Top Crossbeam is a single armed, Top Crossbeam and welding silk braid weld together, swivel nut is fastened in the welding silk braid, and the Top Crossbeam axle then links together by screw thread and swivel nut.Because existing Top Crossbeam is a single armed, be connected for internal and external threads between Top Crossbeam and the axle, also be that reversing by screw thread between Top Crossbeam axle and the Top Crossbeam realized, thereby have following shortcoming: 1. fabrication properties is relatively poor, and matching thread place working accuracy is difficult to guarantee.Car load is prone to the abnormal sound that travels, the moving spacious sound of mechanism, and critical failure such as cause that finally screw thread stripped thread even swivel nut come off.2. the Top Crossbeam bulk strength is low, poor reliability, and service life is short.3. the screw thread fit place lubricating grease of will annotating, cooperation position is less on the vehicle, is difficult to filling, even can't annotates, and very easily causes insufficient lubrication, causes each parts early damage.4. reprocess with maintenance cost higherly, the screw thread silk damages easily, and after the thread failure, whole upper arm can't be repaired, and has only more to renew part.
The purpose of this utility model is to want to overcome above-mentioned the deficiencies in the prior art, and a kind of improved Top Crossbeam is provided--gum cover formula Top Crossbeam, and this gum cover formula Top Crossbeam fabrication properties is good, need not lubricate, long service life, for ease of maintenaince.
For realizing above-mentioned purpose of the present utility model, the technical scheme that is adopted is: the utility model comprises Top Crossbeam axle, Top Crossbeam, welding cover, the welding cover is welded on the Top Crossbeam, its constructional feature is that Top Crossbeam is monolateral for both arms, the welding cover adopts interference fit together with the overcoat in the gum cover outside, the interior cover of Top Crossbeam axle and gum cover inboard adopts free-running fit together, and gum cover is connected with inside and outside cover, the termination of Top Crossbeam axle with self lock nut with interior cover locking.
The two ends of cover preferably are provided with sawtooth in described in the utility model.
In order to strengthen locking intensity, between Top Crossbeam axle head head and self lock nut, be provided with lock washer.
The utility model is owing to adopt both arms, gum cover formula structure, twisting motion between Top Crossbeam axle and the Top Crossbeam is reversed by gum cover and is realized, gum cover has spring performance, shimmy durable, breakage resistant characteristics, thereby makes Top Crossbeam reverse steady noiseless, has greatly improved reliability of products and service life, the gum cover structure need not lubricated, and fabrication properties is good, and overcoat and Top Crossbeam adopt interference fit, and interior cover and Top Crossbeam axle adopt free-running fit, make easy to assembly, be convenient to the maintenance.
Fig. 1 is the structural representation of the utility model embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further detailed description
As seen from Figure 1, Top Crossbeam 3 is monolateral to be both arms, welding cover 2 is welded on the Top Crossbeam 3, and the outside of gum cover 5 is provided with overcoat 4, cover 6 in the inboard is provided with, gum cover 5 adopts rubber to make, overcoat 4 and interior cover 6 all adopt steel bushing, and gum cover 5 passes through sulphurization, overlap 6 in reaching with overcoat 4 and bond together, overcoat 4 adopts interference fit and welding cover 2 to be fitted together, and Top Crossbeam axle 8 adopts free-running fit to be fitted together with interior cover 6.The termination of Top Crossbeam axle 8 is provided with lock washer 7, and by self lock nut 1 locking, interior cover 6 two ends are provided with sawtooth 9, are linked to be an integral body by self lock nut 1 and Top Crossbeam axle 8
