Abstract

The utility model discloses a buffer for motor vehicles, which is composed of a bayonet sleeve, a screw shaft, a nut coat and a chuck shaft. The buffer for motor vehicles is characterized in that a horizontal sliding shaft is processed in the bayonet sleeve; a chunk on the screw shaft can slide on the horizontal sliding shaft; mutually matched external threads and internal threads are respectively processed on the screw shaft and the nut coat; one end of the screw shaft and the chuck shaft is respectively processed with circular abrasive pieces; the rear part of the nut coat is processed with a horizontal sliding chute; a chunk on the chunk shaft can slide in the horizontal sliding chute. The buffer for motor vehicles is also provided with a stopper. The utility model is installed between a gas engine and a driving wheel; the buffer for motor vehicles not only can play the role of a drive shaft, but also can relieve moment impact force and can prolong the lifetime of the motor vehicles.

Description

The automobile buffer device

The utility model relates to self-propelled vehicle, especially relates to a kind of automobile buffer device.

When self-propelled vehicle started, because the too quickly self-propelled vehicle fly start that makes of action of chaufeur, fierce impulsive contact force just caused the damage of components on the self-propelled vehicle easily, shortens the self-propelled vehicle life-span; When self-propelled vehicle overload delivery or emergency brake, because fitting machine motor-car energy disperser not, drive wheel is bigger to the resistance of combustion engine.

The purpose of this utility model is to provide a kind of automobile buffer device that can effectively alleviate the moment impulsive contact force, can prolong the self-propelled vehicle life-span.

The purpose of this utility model is achieved in that the utility model is made up of bayonet socket cover, screw shaft, nut overcoat, dop axle, feature is to be processed with the horizontal concrete chute that slides for the dop on the screw shaft in the bayonet socket cover, postmedian at screw shaft is processed with outside thread, the tail end of screw shaft is processed with circular abrasive disc, in the front portion of nut overcoat, be processed with the negative thread that matches with the outside thread of screw shaft, be processed with the horizontal concrete chute that slides for the dop on the dop axle at the rear portion of nut overcoat, between the circular abrasive disc of dop axle front end and dop, spring be installed.

Be with the hill holder of annular in the outer front end of bayonet socket cover.

The utility model is owing to be processed with supporting negative thread and outside thread mutually on screw shaft and nut overcoat, and design has horizontal concrete chute and spring, and be installed between combustion engine and the drive wheel, just can effectively alleviate the moment impulsive contact force, the power that combustion engine is produced steadily passes to drive wheel effectively, the abrasive disc that hill holder can also be eliminated the abrasive disc of screw shaft and dop axle is the phenomenon of " locked " mutually, so not only played the effect of transmission shaft, and alleviated the moment impulsive contact force, prolonged the life-span of self-propelled vehicle.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of screw shaft.

Fig. 3 is the structural representation of dop axle.

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

The utility model is made up of bayonet socket cover 1, screw shaft 4, nut overcoat 7, dop axle 11, in bayonet socket cover 1, be processed with the horizontal concrete chute 14 that slides for the dop on the screw shaft 43, postmedian at screw shaft 4 is processed with outside thread 5, the tail end of screw shaft 4 is processed with circular abrasive disc 8, in the front portion of nut overcoat 7, be processed with the negative thread 6 that matches with the outside thread 5 of screw shaft 4, be processed with the horizontal concrete chute 13 that slides for the dop on the dop axle 11 12 at the rear portion of nut overcoat 7, between the circular abrasive disc 9 of dop axle 11 front ends and dop 12, spring 10 be installed.

Be with annular in the outer front end of bayonet socket cover 1 with power-transfer clutch bonded assembly hill holder 2.Spring 10 can be formed by taper iron or the coiling of cylinder iron.

After the power of combustion engine produces, the drive bayonet socket overlaps 1 revotating card muzzle 1 and sticks screw shaft 4, screw shaft 4 and nut overcoat 7 produce the relation of screw and nut, screw shaft 4 rotates into nut overcoat 7, circular abrasive disc 8 on the screw shaft 4 will push the circular abrasive disc 9 on the dop axle 11, and spring 10 is squeezed and begins acting, has alleviated impulsive contact force, and give actuator the power smooth transfer, thereby reach buffering effect.Because the self-propelled vehicle its own inertial, screw shaft 4 and dop axle 11 can disengage after extruding a period of time mutually, and extruding is mutually again worked so again and again then.

When external drag is big, " locking " phenomenon can take place in the circular abrasive disc 8 of screw shaft 4 and the circular abrasive disc on the dop axle 11 9, as long as at this moment chaufeur is stepped on pedal of clutch, just can make hill holder 2 locking bayonet sockets cover 1, rely on the self-propelled vehicle its own inertial like this, impel them to separate, thereby cushion next time.
