Planetary Steering Gear Pneumatic Control Device

Abstract

The planetary steering gear pneumatic control device, including the air compressor, the air compressor is connected to the air inlet of the air storage tank through the air pipeline, and the air outlet of the air storage tank is respectively connected to the two-position five-way electromagnetic reversing valve of the left clutch through the pipeline. The pressure gas inlet of the right clutch 2-position 5-way electromagnetic directional valve, the pressure gas inlet of the left brake 2-position 5-way electromagnetic directional valve, the pressure gas of the right brake 2-position 5-way electromagnetic directional valve The inlet is connected with the pressure gas inlet of the electromagnetic control proportional valve. Its purpose is to provide a steering and braking control structure that can greatly simplify the tracked vehicle, increase the working space of the cockpit, allow the driver to drive the tracked vehicle more comfortably, avoid damage to the waist, joints, tendons and other tissues, and significantly improve The flexibility and stability of vehicle steering and braking, low failure rate, stable and reliable planetary steering gear pneumatic control device.

Description

technical field [0001] The invention relates to a pneumatic operating device for a planetary steering gear. Background technique [0002] The track-type driving device has outstanding advantages such as large ground area, good adhesion, strong climbing ability, small turning radius, overcoming obstacles and strong off-road ability, etc. It is widely used in construction machinery, mining machinery, construction machinery, forest firefighting and tank armored vehicles In the action part, the steering principle of tracked vehicles is essentially different from that of wheeled vehicles. The steering of tracked vehicles is achieved by changing the transmission ratio from the engine to the tracks on both sides, so that the speeds of the tracks on both sides are different. Simple and widely used in the steering device of high-speed tracked vehicles. At present, the planetary steering gear is mostly operated by mechanical control, the control mechanism occupies a large space, ther...

AI Technical Summary

Problems solved by technology

At present, the planetary steering gear is mostly operated by mechanical control, the control mechanism occupies a large space, there are many control parts, the structure layout is not compact, the control force is large, the operation stroke is long, the human-machine relationship is not coordinated, the joint operation of both hands is required, and the driver is prone to fatigue. In addition, the space in the cockpit of this type of vehicle is small. In addition to the driving control parts, there are other operating parts of the working mechanism in the cockpit. The design and layout of the operating mechanism are greatly restricted. High, and will occupy the precious cab space, resulting in unreasonable working space in the cockpit of the tracked vehicle, sometimes the driver's driving posture is in a forced position, and even the height of the driver is restricted

The driver works in an unreasonable posture for a long time, causing pain in the driver's trunk and limbs. After working for a long time, the driver is prone to fatigue, joints, tendons and other tissues are prone to permanent damage, resulting in occupational diseases. Wartime Seriously affect the driver's continuous combat capability
