Preferably, a plate spring is connected between the two support rods in the support rod group.

Preferably, both ends of the plate spring are disposed in different vertical planes.

Preferably, the arc-shaped limiting plate is fixedly provided with a cushion pad.

Preferably, extension plates are arranged on the outer edges of the two end ports of the annular shell.

The beneficial effects of the utility model embody in following aspect:

1. the utility model discloses an at the transmission shaft can go up to install damper to set up damper's arc limiting plate in the spacing recess of annular housing, set up at inner ring spring all around and bracing piece mutually supporting through circular symmetry, when the transmission shaft takes place relative vibration, be of value to and play the cushioning effect from the vibration of each angle of casing of transmission shaft to the transmission shaft, and then improve transmission shaft life.

FIG. 2 is a schematic view of the construction of the annular housing;

fig. 3 is a schematic structural view of the damper mechanism.

In the figure: 1 transmission shaft, 2 axle casings, 3 annular shell, 4 mounting substrate, 5 spacing recesses, 6 extension boards, 7 bracing pieces, 8 spring baffle, 9 springs, 10 leaf springs, 11 arc limiting plates, 12 blotters, 13 inner rings.

Detailed Description

The present invention will be further described with reference to the following embodiments, wherein the drawings are for illustrative purposes only and are not intended to be limiting, and in order to better illustrate the embodiments of the present invention, some components of the drawings may be omitted, enlarged or reduced and do not represent the size of an actual product.

As shown in fig. 1 to 3, a shock absorber device for a drive shaft of an automobile chassis, comprising: the damping mechanism comprises an annular shell, wherein mounting base plates are arranged at two ends of the outer wall of the annular shell, limiting grooves which are circumferentially arranged along the annular shell and are closed end to end are formed in the inner wall of the annular shell, and extension plates are arranged at the outer edges of ports at two ends of the annular shell, so that the stability of the damping mechanism in the annular shell is improved, and the inner ring and the annular shell are prevented from being dislocated;

a damper mechanism comprising: the inner ring, the suit can be fixed on the casing outer wall of transmission shaft to the inner ring, and a plurality of bracing piece group use inner ring center as centre of a circle, circular symmetry sets up on inner ring outer wall, and circular symmetry is provided with and benefits to guaranteeing can both play the cushioning effect to the vibration of transmission shaft on a plurality of angles of the radial direction of transmission shaft, cushions the impact force of a plurality of angles, is of value to the shock absorber's that improves cushioning performance, bracing piece group includes two bracing pieces, the one end fixed mounting of bracing piece is on inner ring outer wall, two in the same bracing piece group the bracing piece is kept away from inner ring one end and is articulated with the both ends of arc limiting plate respectively, and spring baffle fixed mounting is on the bracing piece, and spring suit is on the bracing piece and set up in the middle of spring baffle and inner ring, and each bracing piece group corresponds the arc limiting plate is all fixed in limiting groove, and fixed mounting has the blotter on the arc limiting plate is of being of value to further improving damper at radial shock attenuation effect.

The utility model discloses a theory of operation: the utility model discloses an installing damper on the transmission shaft to with damper's arc limiting plate setting in the spacing recess of annular housing, setting mutually supports at inner ring spring all around through circular symmetry, when relative vibration takes place for the transmission shaft, is of value to playing the cushioning effect, specific to the vibration of transmission shaft from each angle of casing of transmission shaft:

in the transmission shaft working process, when the shaft housing takes place relative vibration because the influence of transmission shaft, the shaft housing can extrude the arc limiting plate that corresponds the position with annular shell interact power, arc limiting plate compression spring, cushion the interaction power between the two through the spring, wherein the arc limiting plate is established to the arc and can closely laminate spacing recess, guarantee the stability of the arc limiting plate among the buffering process, each cowl circular symmetry sets up around the inner ring, can cushion the effort of the radial ascending multi-angle of transmission shaft when the spring cushions, be of value to the shock attenuation buffering efficiency that improves the bumper shock absorber. And be connected with the leaf spring between two bracing pieces in the bracing piece group, the leaf spring is of value to the relatively steady orientation of guaranteeing two bracing pieces on the one hand, and the bracing piece skew is too big when preventing the spring compression, influences normal buffering effect, and on the other hand also can cushion the ascending vibration of transmission shaft axial, has improved damping device's buffering effect. It plays a role in buffering the vibration of the transmission shaft from all angles of the shell of the transmission shaft to be beneficial, and further the service life of the transmission shaft is prolonged.
