Embodiment Construction

[0022] refer to Figure 3-4 , the specific embodiment adopts the following technical solutions: self-propelled aerial work vehicle axle balance control system, mainly including front axle 1, balance oil cylinder 2, balance valve 3, vehicle frame 4, solenoid valve 5, shuttle valve 6, rear axle 7. Both ends of the two balance oil cylinders 2 are connected to the axle 4 and the front axle 1 respectively. Rear axle 7 is rigidly connected with vehicle frame 4. The front axle 1 is connected with the vehicle frame 4 through a pin shaft 3 .

[0023] The role of the shuttle valve 6 in this specific embodiment: the axle balance system controls the oil power source. When the vehicle is running, port A (or port B) builds up pressure to drive the traveling motor, and the shuttle valve 6 can automatically compare the pressures of port A and port B, and select a higher pressure as the power source of the axle balance system.

[0024] Solenoid valve 5 of this specific embodiment: used to c...

Abstract

The invention discloses an axle balance control system of a self-walking type aerial working vehicle. The system mainly comprises a front axle, a balance oil cylinder, a balance valve, a vehicle frame, an electromagnetic valve, a shuttle valve and a rear axle, wherein two ends of a hydraulic oil cylinder are connected onto the vehicle frame and the front axle above the vehicle and an axle respectively, the balance oil cylinder is connected with the electromagnetic valve through the balance valve, the electromagnetic valve is connected with the shuttle valve, the rear axle is in rigid connection with the vehicle frame, and the front axle is connected with the vehicle frame through a hinge pin. The axle balance control system overcomes defects that drive wheels cannot be grounded simultaneously, a suspension wheel idles and driving force of a vehicle in running is insufficient when a self-walking type aerial working platform runs on an uneven road surface; the safety of aerial working can be guaranteed due to the rigid connection of the axle and the vehicle frame in the operation process.

Description

technical field [0001] The invention relates to the technical field of self-propelled high-altitude operations, in particular to a self-propelled high-altitude operation vehicle axle balance control system. Background technique [0002] Self-propelled aerial work platforms are mainly used in construction, steel structure, venues and leasing industries. Most of the time, the ground conditions of the work site are poor, with many potholes and obstacles, and the vehicle needs to change the working position frequently during the operation process. Or transition, so the driving performance of the vehicle and the ability to adapt to the road are very high. [0003] In the past, the front and rear axles of the aerial work platform were rigidly connected to the chassis. When driving on uneven ground, the driving wheels could not touch the ground at the same time, and the suspension wheels idling, resulting in insufficient driving force for the vehicle to move forward. [0004] The ...
