Silicon oil integrated shock absorber for vehicle cab

Abstract

The invention belongs to the technical field of dampers, and particularly relates to an integrated silicon oil damper for a cab of a vehicle. The integrated silicon oil damper for the cab of the vehicle comprises a silicon oil cavity and a vulcanized rubber piece, wherein the silicon oil cavity is filled with silicon oil; the vulcanized rubber piece is hermetically connected to the silicon oil cavity; a supporting inner core penetrates in the center of the vulcanized rubber piece; the upper end of the supporting inner core is connected with an upper cover plate; the lower end of the supporting inner core is connected with a guiding damping fin; an oil storage cavity is formed between the upper surface of the guiding damping fin and the bottom of the vulcanized rubber piece; the guiding damping fin is limited and fixed through a projection on the bottom of the supporting inner core; the outer end of the guiding damping fin is upwards bent to form a ring; a sealing ring is arranged between the vulcanized rubber piece and the silicon oil cavity; and the vulcanized rubber piece is in vulcanized connection with a connecting plate. The integrated silicon oil damper for the cab of the vehicle is simple in structure; a vehicle damping effect can be effectively achieved; and moreover, the damper is provided with an overturn-preventing structure, and a phenomenon that the cab overturns under the condition of large-load vibration can be avoided.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, in particular to a silicone oil-integrated shock absorber for vehicle cabs. Background technique [0002] At present, the cabs of construction machinery and special vehicles are generally directly installed and fixed on the frame, or indirectly installed on the frame through rubber parts. Because the environment that this type of vehicle travels is the irregular road surface in the field, the terrain is complex and the ups and downs are large. The vibration of the cab will cause extreme uneasiness to the driver, and at the same time, it will cause damage to the components of the cab under long-term vibration, resulting in unpredictable safety problems. [0003] Silicone oil shock absorber is a device for isolating and reducing vibration, which has been widely used in the field of vibration isolation of construction machinery, especially in the vibration isolation of the cab. However, th...

AI Technical Summary

Problems solved by technology

The design of the rear port and the oil injection hole may cause leakage of silicone oil during use, which will make the shock absorber invalid and greatly increase the maintenance work in the later period
