Description

Rear pull rod suspension

Technical Field

The utility model relates to a back pull rod suspension technical field specifically is a back pull rod suspension.

Background

The buffer structure (stop) is mainly used for a front/rear suspension system, but is common in a power assembly system (mainly expressed in working conditions of acceleration, deceleration, sharp turning and road surface), particularly when an automobile runs, a tire and the road surface vibrate, a vehicle body is a vibration-proof object in the state, a chassis is a vibration source, the buffer structure is used for relieving impact during vibration, the vibration is quickly reduced through the damping characteristic of the buffer structure, and meanwhile when the excessive impact is met, the noise generated by the buffer structure of the existing rear pull rod suspension is relatively more, the production cost is high, the processing difficulty is high, the mass production is not facilitated, and the service life is shorter.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a back pull rod suspension to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a back pull rod suspension comprises an aluminum support, wherein the aluminum support comprises a rod body, a large bushing end and a small bushing end are arranged at two ends of the rod body, a large bushing and a small bushing are respectively arranged in the large bushing end and the small bushing end, the small bushing comprises an anti-torsion inner core, an anti-torsion damper and an outer sleeve, the anti-torsion damper is arranged in the anti-torsion inner core, the outer sleeve is arranged in the anti-torsion damper, the large bushing comprises a limiting part, a buffer block and a main spring inner core, the main spring inner core is arranged at a position close to the left side of the inner wall of the large bushing end, a circular connecting hole and a special-shaped lightening hole are formed in the main spring inner core, the limiting part is in an arch shape and comprises a vulcanized rubber rib and a metal limiting block which are used for connecting the main spring inner core and the inner wall of the large bushing end, the metal limiting block is arranged on the inner wall of the large bushing end, and, the groove is arranged in the middle of the vulcanized rubber rib block.

Preferably, the metal limiting block is an aluminum limiting block.

Preferably, the closest horizontal linear distance between one end of the buffer block far away from the main spring inner core and the inner wall of the end of the large bushing is the same as the closest linear distance between one end of the metal limiting block close to the main spring inner core and the bottom of the groove.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses, low in production cost, the processing degree of difficulty is low, does benefit to batch production, and the locating part is the arch form, has reduced the noise that produces when using, adopts vulcanized rubber muscle piece moreover, has prolonged the life of this equipment.

FIG. 2 is a schematic view of the structure of the large bushing of the present invention;

fig. 3 is a schematic view of the structure of the small bushing of the present invention.

In the figure: 1. a small bushing end; 2. a main spring inner core; 3. a limiting member; 4. a large bushing end; 5. a metal stopper; 6. vulcanizing the rubber rib block; 7. a circular connection hole; 8. a buffer block; 9. special-shaped lightening holes; 10. an anti-torsion inner core; 11. a torsional damper; 12. and (4) coating.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a back pull rod suspension comprises an aluminum support, the aluminum support comprises a rod body, a large bushing end and a small bushing end are arranged at two ends of the rod body, a large bushing and a small bushing are respectively arranged in the large bushing end and the small bushing end, the small bushing comprises an anti-torsion inner core, an anti-torsion damper and an outer sleeve, the anti-torsion damper is arranged in the anti-torsion inner core, the outer sleeve is arranged in the anti-torsion damper, the large bushing comprises a limiting piece, buffer block, main spring inner core sets up in the left position of being close to big bush end inner wall, is provided with circular connecting hole and dysmorphism lightening hole on the main spring inner core, and the locating part is the arch form, and the locating part is including vulcanized rubber rib piece and the metal stopper that is used for main spring inner core and big bush end inner wall connection, and the metal stopper sets up on big bush end inner wall, and the recess on metal stopper and the vulcanized rubber rib piece suits, and the middle part of recess setting on vulcanized rubber rib piece.

Specifically, the metal limiting block is an aluminum limiting block, so that the weight is light, and the cost is low.

Specifically, the nearest horizontal linear distance between one end of the buffer block far away from the main spring inner core and the inner wall of the large bushing end is the same as the nearest linear distance between one end of the metal limiting block close to the main spring inner core and the bottom of the groove, the pulling of the rubber rib block is reduced, and the service life of the rubber rib block is prolonged.

The working principle is as follows: the circular connecting hole is used for being connected with the gearbox, and the locating part is used for spacing main spring inner core, and the locating part is the arch shape, fine reduction the noise in the use.
