Problems solved by technology

[0002] Large-scale engineering vehicles, such as road rollers and bulldozers, vibrate greatly during operation, especially when the road roller is running on an uneven road surface, the overall vibration of the vehicle is more obvious, and the driver is prone to fatigue when driving the vehicle for a long time in this vibration environment. Discomfort, etc., the existing seat will install a spring support to filter the vibration of the road, but the spring itself will reciprocate, and the shock absorber is used to suppress the jumping vibration of the spring. If the shock absorber is too soft It will jump up and down, and the shock absorber will bring too much resistance if it is too hard, which will affect the normal work of the air spring

Embodiment Construction

[0017] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific examples. The examples are implemented on the premise of the technical solutions of the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0018] Such as figure 1 As shown, a vehicle seat spring shock absorber includes a top plate 1, a bottom plate 2, a mounting seat 3, an air spring 4 and an elastic ball shock absorber 5, and the air spring 4 is vertically installed between the top plate 1 and the bottom plate 2, The elastic ball damping device 5 is vertically arranged in the central annular space of the air spring 4, and the central axes of the air spring 4 and the elastic ball damping device 5 coincide. The elastic ball damping device 5 includes a piston rod 51 fixed on the lower surface of the top plate 1 and a piston cylinde...

Abstract

The invention discloses a vehicle seat spring damping device. The vehicle seat spring damping device includes a top plate, a bottom plate, a mounting seat, an air spring and an elastic ball damping device. The air spring is vertically mounted between the top plate and the bottom plate. The elastic ball damping device is vertically arranged in central annular space of the air spring. The elastic ball damping device includes a piston rod fixed to the lower surface of the top plate and a piston barrel fixed to the upper surface of the bottom plate. A piston barrel cover is mounted on the upper end of the piston barrel. A piston head extending into the piston barrel is arranged on the lower end of the piston rod. Space which is in the piston barrel and located under the piston head is a cavity. The cavity is filled with elastic balls. The vehicle seat spring damping device of the invention utilizes the combination design of the rubber air spring and the elastic ball damping device, and sothe damping effect of a vehicle seat is better, vibration generated by bump of a road surface is greatly eliminated, and more comfortable driving environment is provided for a driver.

Description

technical field [0001] The invention belongs to the technical field of vehicle damping, and in particular relates to a vehicle seat spring damping device. Background technique [0002] Large-scale engineering vehicles, such as road rollers and bulldozers, vibrate greatly during operation, especially when the road roller is running on an uneven road surface, the overall vibration of the vehicle is more obvious, and the driver is prone to fatigue when driving the vehicle for a long time in this vibration environment. Discomfort, etc., the existing seat will install a spring support to filter the vibration of the road, but the spring itself will reciprocate, and the shock absorber is used to suppress the jumping vibration of the spring. If the shock absorber is too soft It will jump up and down, and if the shock absorber is too hard, it will bring too much resistance, which will affect the normal work of the air spring. Contents of the invention [0003] Purpose of the inven...
