Abstract

The invention discloses a gearbox suspension bushing. The gearbox suspension bushing comprises an inner core, a rubber part, a framework and a bracket; the middle part of the inner core is a columnarstructural part marked as a middle core part; the framework is a fan-ring-shaped structural part and located below the inner core; the rubber part comprises an inner pipe wrapping the periphery of themiddle core part, supporting parts arranged on the left side and the right side of the lower portion of the inner pipe and an outer ring wrapping the framework; the upper end face of the inner pipe protrudes outwards to form a bulge; the rubber part is assembled in the bracket, and the bulge of the inner pipe is in interference connection with the inner wall face of the bracket. The structural arrangement of a traditional bushing is changed, and the material cost is reduced.

Description

technical field [0001] The invention relates to an automobile part, in particular to a gearbox suspension bushing. Background technique [0002] The automobile transmission suspension suspension shock absorber is the main part used to ensure the stable operation of the automobile transmission. The rotation of the automobile engine and the bumps generated by the vehicle will add dynamic pressure, causing vibration and noise in related parts. If the vibration amplitude is close to the resonance amplitude, it will cause damage to the gearbox and its related parts, and the strength, efficiency and life will be reduced. The suspension and shock absorbing device of the automobile gearbox plays a very important role in shock absorption and noise reduction. Therefore, the performance of the suspension and damping device of the automobile gearbox is of great benefit to reducing noise, prolonging the life of the automobile, and improving the comfort of the automobile. [0003] At pr...
