Vibration damping device for automotive gearbox installed in series damping plate

Abstract

The invention relates to an automobile transmission and discloses a vibration damping plate tandem mounting vibration damper of an automobile transmission. The vibration damper comprises a mounting plate and a cross beam, wherein the mounting plate is provided with two support tables; each support table is provided with a vibration damping rod and at least two support rods; the mounting plate is provided with vibration damping cylinders; the lower ends of the support rods are arranged in the vibration damping cylinders in a penetrating manner; the support rods are provided with energy dissipation blocks; first friction layers are arranged on periphery surfaces of the vibration damping cylinders; the energy dissipation blocks are provided with second friction layers; the energy dissipation blocks are propped against the first friction layers via the second friction layers and connected into the vibration damping cylinders in a sliding manner; arc steel spring plates supported below the cross beam are connected with the vibration damping rods; and a transmission connecting frame is arranged on the cross beam. The vibration damping plate tandem mounting multistage vibration damper of the automobile transmission solves the problem that the existing transmission does not meet vibration damping requirements when in use.

Description

technical field [0001] The invention relates to an automobile transmission case, in particular to an automobile transmission vibration damping device installed in series with vibration damping plates. Background technique [0002] Automobile transmission (Transmission) is often called "gearbox" in automobiles; it is often called "speed changer" in industrial machinery, and it is a mechanical or hydraulic device for mechanical power conversion. [0003] The transmission is one of the main components of the car transmission system. The actual use of the car is very complicated, such as starting, idling, low or high speed driving, acceleration, deceleration, climbing and reversing, etc., which requires that the driving force and speed of the car can be changed in a considerable range. The output torque and speed variation range of the adopted piston engine are small. In order to adapt to changing driving conditions and make the engine work under favorable conditions (higher p...
