Description

Transmission shaft hanger with damping spring

Technical Field

The invention discloses a transmission shaft hanger with a damping spring, belongs to the field of automobile accessories, and particularly relates to a hanger with a transmission shaft damping through the damping spring.

Background

The transmission shaft for with the power transmission of derailleur for the drive mechanism of rear axle, middle-size and small-size car generally only needs a transmission shaft, and heavy truck person needs many to establish ties, and the transmission shaft need use the gallows to fix the transmission shaft at the in-process of establishing ties, but the transmission shaft can produce vibrations when high-speed rotation and the truck shake of in-process of traveling makes the transmission shaft gallows need increase damping system and reduce the shake when high-speed rotation. The existing transmission shaft manufacturers are low in cost and easy to process the rubber sleeves, and the produced transmission shaft hanging bracket basically adopts the rubber sleeves as a damping system, but the rubber sleeves are affected by air temperature, and can be hardened, reduce the damping effect and even crack in winter with lower air temperature, so that the transmission shaft hanging bracket cannot be used. Therefore, there is a need for a transmission shaft hanger which is not affected by air temperature, is durable, and has excellent shock absorption effect, instead of the existing rubber bush hanger.

Disclosure of Invention

The transmission shaft hanger with the damping spring overcomes the defects, adopts the rectangular connecting plate, the central authorities at connecting plate below both ends have set up a bracket respectively perpendicularly, the annular holding ring of circle has been set up between two bracket belows, the inside of holding ring has set up volute type damping spring, damping spring's center has set up annular bearing housing, the inside of bearing housing has set up annular universal bearing, universal bearing's inside has set up the columniform transmission shaft, the truck is at the high-speed rotatory and the shake of truck self of transmission shaft make the transmission shaft high frequency vibrations of in-process of traveling, the transmission shaft passes through universal bearing and bearing housing and transmits the shock wave to damping spring at the in-process of high frequency vibrations, damping spring absorbs most shock waves through self quick flexible, the residual wave that incompletely absorbed transmits the holding ring through damping spring and absorbs it.

A transmission shaft hanger with a damping spring is characterized by comprising a connecting plate, a bracket, a positioning ring, the damping spring, a bearing sleeve, a universal bearing, a transmission shaft, a connecting plate mounting hole and a convex fork;

the connecting plate is rectangular and is longitudinally arranged below the middle part of a truck girder, two oval connecting plate mounting holes are respectively arranged at two ends of the connecting plate and are respectively connected with the lower part of a truck middle beam through a bolt, a rectangular bracket is respectively vertically arranged below the middle parts of two sides of the connecting plate, an annular positioning ring is vertically arranged between the lower parts of the two brackets, a volute type damping spring is arranged in the positioning ring, and an annular bearing sleeve is arranged at the center of the damping spring;

universal bearing sets up in the inside of bearing housing through C type jump ring respectively for ring shape, both sides, and universal bearing's inside has set up columniform transmission shaft, the top on transmission shaft left side is connected with flexible fork through cylindric flexible cover, the top on transmission shaft right has set up the protruding circle fork of C type, the protruding circle fork passes through the cross and is connected with the flexible fork of second grade transmission shaft.

Has the advantages that: the existing transmission shaft manufacturers are low in cost and easy to process the rubber sleeves, and the produced transmission shaft hanging bracket basically adopts the rubber sleeves as a damping system, but the rubber sleeves are affected by air temperature, and can be hardened, reduce the damping effect and even crack in winter with lower air temperature, so that the transmission shaft hanging bracket cannot be used. The utility model provides a transmission shaft gallows with damping spring, the truck is at the high-speed rotation of in-process transmission shaft and the shake of truck self make transmission shaft high frequency vibrations, the transmission shaft passes through universal bearing and bearing housing at the in-process of high frequency vibrations and transmits the shock wave for damping spring, damping spring absorbs most shock waves through self quick flexible, the remaining ripples that the complete absorption was fallen pass through damping spring and transmit the holding ring and absorb it.

Detailed Description

The shape and construction of the present invention will now be described in detail with reference to the accompanying drawings and reference numerals:

a transmission shaft hanger with a damping spring is characterized by comprising a connecting plate 1, a bracket 2, a positioning ring 3, a damping spring 4, a bearing sleeve 5, a universal bearing 6, a transmission shaft 7, a connecting plate mounting hole 8 and a convex fork 9;

the connecting plate 1 is rectangular and is longitudinally arranged below the middle part of a truck girder, two oval connecting plate mounting holes 8 are respectively arranged at two ends of the connecting plate 1, the two connecting plate mounting holes 8 are respectively connected with the lower part of a truck middle beam through a bolt, a rectangular bracket 2 is respectively and vertically arranged below the middle parts of two sides of the connecting plate 1, an annular positioning ring 3 is vertically arranged between the lower parts of the two brackets 2, a volute type damping spring 4 is arranged inside the positioning ring 3, and an annular bearing sleeve 5 is arranged at the center of the damping spring 4;

universal bearing 6 sets up in the inside of bearing housing 5 for ring shape, both sides respectively through C type jump ring, and universal bearing 6's inside has set up columniform transmission shaft 7, and the top on transmission shaft 7 left side is connected with flexible fork through cylindric flexible cover, and the top on transmission shaft 7 right has set up the protruding circle fork 9 of C type, and protruding circle fork 9 passes through the cross and is connected with the flexible fork of second grade transmission shaft.

When the transmission shaft hanger with the damping spring is used, a driver drives a truck to run on a road, the engine transmits power to the transmission, the transmission transmits power to the transmission shaft, the transmission shaft transmits power to the secondary transmission shaft, the secondary transmission shaft transmits power to the rear axle to drive wheels to push the truck to advance, the transmission shaft vibrates at high frequency due to high-speed rotation of the transmission shaft and self shaking of the truck, the transmission shaft transmits vibration waves to the damping spring through the universal bearing and the bearing sleeve in the high-frequency vibration process, the damping spring absorbs most of the vibration waves through self quick expansion and contraction, and the incompletely absorbed residual waves are transmitted to the positioning ring through the damping spring to be absorbed.

The above-mentioned non-detailed description is prior art.

The foregoing is merely a general disclosure of the invention and is not intended to limit the invention in any way; those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the scope of the invention as defined by the appended claims.
