Limiting shock attenuation device connecting forklift truck cab with frame

Abstract

The invention provides a limiting shock attenuation device connecting a forklift truck cab with a frame. The limiting shock attenuation device connecting the forklift truck cab with the frame comprises a base. A shock attenuation block is arranged in the base, and a fastener is buried into the shock attenuation block. The upper end of the fastener penetrates out of a limiting block on the top end face of the shock attenuation block and is fixedly connected with the limiting block. According to the integrated structure integrating the shock attenuation block and a fastener connection bolt, the assembling efficiency is improved; a damping gasket and the bottom end of the connection bolt are connected and buried into the shock attenuation block, and the shock attenuation effect is improved; due to the fact that folded edges of the two ends of a limiting board are matched with flangings of a box body of the base, the oscillation range of the cab is limited, and therefore driving safety and driving stability are improved.

Description

technical field [0001] The invention relates to the technical field of forklifts, in particular to a position-limiting shock-absorbing device for connecting a forklift cab and a vehicle frame. [0002] Background technique [0003] Since the cab of a forklift is generally installed directly on the frame, they are rigidly connected, and the vibration of the engine and the impact of the road surface when the vehicle is running will be directly transmitted to the cab, resulting in poor stability of the cab. poor comfort. [0004] With the continuous improvement of people's requirements for vehicle driving comfort, flexible connections are also used between the cab and the frame at present, that is, rubber pads are added to the connection between the forklift cab and the frame to absorb shocks. shock effect, but it needs to be used in conjunction with fasteners, resulting in low assembly efficiency; in addition, because the fasteners are too tight or too loose, the shock-absor...

Problems solved by technology

[0003] Since the cab of a forklift is generally installed directly on the frame, they are rigidly connected, and the vibration of the engine and the impact of the road surface when the vehicle is running will be directly transmitted to the cab, resulting in poor stability of the cab. poor comfort

[0004] With the continuous improvement of people's requirements for vehicle driving comfort, flexible connections are also used between the cab and the frame at present, that is, rubber pads are added to the connection between the forklift cab and the frame to absorb shocks. shock effect, but it needs to be used in conjunction with fasteners, resulting in low assembly efficiency; in addition, because the fasteners are too tight or too loose, the shock-absorbing pad is pressed too tightly or too loosely, resulting in the actual damping The shock effect is not ideal

Moreover, due to the unlimited function of the connecting device, when the forklift is turning sharply or driving on a bumpy road, the cab shakes without restriction and the amplitude is too large, which makes the driver feel unsafe.
