Multidimensional Buffer Shock Absorber for Construction Vehicle Cab

Abstract

The invention discloses a multi-dimensional buffer shock absorber for engineering vehicle cabs, that is, the front end of the shock absorber is open and the bottom end is centered with a mounting hole, a flange is arranged on the outer ring of the front end of the shell, and rubber The outer ring of the sleeve is provided with several grooves at intervals along the circumferential direction. The rubber sleeve is set in the housing and the outer ring of the rubber sleeve is against the inner ring of the housing. The spring sleeve is arranged on the inner ring of the rubber sleeve and is spaced from the bottom of the housing. The front end of the spring sleeve is against the end face of the rubber sleeve. The front end of the core rod is provided with an external thread and penetrates into the disc. The spring seat is located at the bottom end of the core rod and is located in the spring sleeve. Between the spring seats, the head is arranged in the installation hole at the bottom of the shell, and the fixing nut is screwed on the external thread at the front end of the core rod. The shock absorber significantly slows down the up and down bumps of the engineering vehicle cab, and can buffer the radial impact on the cab caused by vehicle acceleration, braking, and turning centrifugal force, which improves the driver's operating comfort and greatly eliminates driving safety. .

Description

technical field [0001] The invention relates to a multi-dimensional buffer shock absorber for engineering vehicle cabs. Background technique [0002] Mobile construction machinery includes frame vehicles, excavators, forklifts, bulldozers, etc. Since such vehicles do not have chassis suspension systems like ordinary buses and trucks, the cab and frame are basically rigidly connected, and uneven ground will cause The whole vehicle is bumpy. During the driving and operation of the vehicle, the cab is in a bumpy state simultaneously, which directly affects the safe operation and comfort of the driver. For example, during the use of the frame car, due to severe bumps, the driver may be vacated, resulting in the short-term separation of the feet from the accelerator and brake pedals, which not only causes the driver's lack of comfort, but also causes great safety hazards in driving and operation. . [0003] At present, in order to reduce the jolt intensity of the driver, the mo...

Problems solved by technology

[0002] Mobile construction machinery includes frame vehicles, excavators, forklifts, bulldozers, etc. Since this type of vehicle does not have a chassis suspension system like ordinary buses and trucks, the cab and the frame are basically rigidly connected, and the unevenness of the ground will cause The whole vehicle is bumpy. During the driving and operation of the vehicle, the cab is in a bumpy state simultaneously, which directly affects the safe operation and comfort of the driver.

For example, during the use of the frame car, due to severe bumps, the driver may be vacated, causing both feet to be separated from the accelerator pedal and brake pedal for a short time, which not only causes the driver's lack of comfort, but also causes great safety hazards in driving and operation.
