Abstract
The invention discloses a swing type hydraulic adjustable hanging articulated steering chassis which increases the locomotive chassis height in a portable drive bridge manner, improves the space under the locomotive chassis, and changes independent hanging heights to adapt to different bumpy pavements. The chassis comprises a front drive axle, a rear drive axle, a drive cantilever, a servo hydraulic cylinder, a drive connecting rod, a hydraulic oil tank, a hydraulic drive motor, a transfer case, a steering oil cylinder, an articulated device, a front frame, a rear frame, an engine, a hydraulic pump, a front drive wheel and a rear drive wheel. The chassis adopts a hydraulic drive walking system, and a hydraulic motor is driven by the hydraulic pump to drive the front drive wheel and the rear drive wheel to advance. The steering is carried out by an articulated steering mechanism and a steering oil cylinder.
Description
Technical field
The invention belongs to the chassis technology field, be specifically related to a kind of swing type hydraulic and can regulate suspension articulated steering chassis.
Background technology
Construction machinery and equipment need carry out the adjusting of chassis ground Clearance when carrying out operation, the chassis attitude keeps requiring each independent suspension to keep center-of-gravity position and front and back drive wheel power on rugged and rough road surface, by hydraulic efficiency servo the height of swing arm type suspension is regulated and to be realized that job platform hangs for the real-time response of each drive wheel to place Different Ground height, play damping, keep the operation center of gravity, improve the purpose of traveling comfort.
Summary of the invention
The purpose of this invention is to provide a kind of four wheel drive oscillating type adjustable hanging chassis, can be at the work of assurance chassis attitude stabilization, balance four wheel drive power strengthens by performance and obstacle climbing ability.
Swing type hydraulic provided by the invention can be regulated and hang the articulated steering chassis, it is characterized in that: hydraulic-drive running system is adopted on the chassis, the power of driving engine (13) output is given Hydraulic Pump (14) through the power distribution of auxiliary gear box (8), Hydraulic Pump (14) forms drive system by hydraulic circuit and hydraulic drive motor (7), drive front driving axle (1) and rear driving axle (2) jointly by drive link (5) simultaneously, by front driving wheel (15) and rear drive sprocket (16), utilize Hydraulic Pump (14) power driven HM Hydraulic Motor (7) drive front driving wheel (15) and rear drive sprocket (16) to advance; The chassis utilization is bowed hinged (10) and is turned to oil cylinder (9) formation articulated steering system drive front vehicle frame (11), back vehicle frame (12) to form corner and turn to; Drive cantilever (3) and constitute independent suspension system with servo hydraulic cylinder (4), the stroke adjustment by servo hydraulic cylinder (4) makes front driving wheel (15) be in the diff-H different with chassis system, to strengthen the performance of passing through on chassis.
Servo-cylinder in each drive wheel system of the present invention is accepted the platform pose and is adjusted signal, the promotion oscillating type cantilever that distributes swings to adjust its height, keep the chassis attitude, kept center-of-gravity position and four-wheel distribution of pressure balance, reached the requirement of obstacle detouring and enhancing crossing ability.
Description of drawings
Fig. 1 can regulate power and the structural system theory of constitution figure that hangs the articulated steering chassis for swing type hydraulic;
Fig. 2 reaches maintenance chassis attitude stabilization scheme drawing by regulating the driving cantilever for adjustable suspension chassis by rugged road surface the time.
The specific embodiment
Former and later two mechanical type drive axles are installed on the chassis of the present invention, including front driving axle (1) is installed on the front vehicle frame (11), and rear driving axle (2) is installed on the back vehicle frame (12), described front and back drive axle is driven by the hydraulic drive motor (7) that is installed on the rear driving axle (2), and by drive link (5) with transmission of power to front driving axle (1).
(12) have adopted articulated steering formula articulated structure between front vehicle frame (11) and the back vehicle frame, specifically turn to oil cylinder (9) also to connect the front and back drive axle respectively in the vehicle bridge both sides by two, and vertical hinged (10) cooperation of bowing between the vehicle bridge of front and back has constituted hydraulically powered steering hardware.The chassis utilizes articulated steering mechanism to bow hinged (10) and turns to oil cylinder (9) formation articulated steering system drive front vehicle frame (11), back vehicle frame (12) to form corner and turn to.
The front and back that the independent hydraulically controlled cantilever suspension type of a kind of four-wheel articulated steering base apparatus is equipped drive vehicle bridge, its two ends are separately installed with and drive cantilever (3), driving cantilever (3) utilizes swing bearing to be connected with the drive axle end, stroke by servo hydraulic cylinder (4) increases or reduces, the hydraulic actuating cylinder hinge-point swings up and down driving cantilever (3), and take place with the angle of vehicle frame, the drive wheel of cantilevered distal end is raise or reduction, formation is the cantilever suspension type drive wheel of luffing just, the other end of its vehicle bridge and other vehicle bridge are also herewith managed, but form the cantilevered suspension driving chassis system of the equal luffing of height of each drive wheel.Drive cantilever (3) and constitute independent suspension system with servo hydraulic cylinder (4), it is poor that the stroke adjustment by servo-cylinder is in the chassis system differing heights front driving wheel (15), passes through performance to strengthen the chassis.
Power output system is installed on the back vehicle frame (12), rely on driving engine (13) output mechanical power, adopt hydraulic-drive running system, the power of driving engine (13) output is given Hydraulic Pump (14) through the power distribution of auxiliary gear box (8), Hydraulic Pump (14) forms drive system by hydraulic circuit and hydraulic drive motor (7), drive front driving axle (1) and rear driving axle (2) jointly by drive link (5) simultaneously, utilize Hydraulic Pump (14) power driven HM Hydraulic Motor (7) drive front driving wheel (15) and rear drive sprocket (16) to advance.
Claims (2)
1. swing type hydraulic can be regulated and hang the articulated steering chassis, it is characterized in that:
Hydraulic-drive running system is adopted on the chassis, the power of driving engine (13) output is given Hydraulic Pump (14) through the power distribution of auxiliary gear box (8), Hydraulic Pump (14) forms drive system by hydraulic circuit and hydraulic drive motor (7), drive front driving axle (1) and rear driving axle (2) jointly by drive link (5) simultaneously, by front driving wheel (15) and rear drive sprocket (16), utilize Hydraulic Pump (14) power driven HM Hydraulic Motor (7) drive front driving wheel (15) and rear drive sprocket (16) to advance; The chassis utilization is bowed hinged (10) and is turned to oil cylinder (9) formation articulated steering system drive front vehicle frame (11), back vehicle frame (12) to form corner and turn to.
2. chassis according to claim 1, it is characterized in that: drive cantilever (3) and constitute independent suspension system with servo hydraulic cylinder (4), stroke adjustment by servo hydraulic cylinder (4) makes front driving wheel (15) be in the diff-H different with chassis system, to strengthen the performance of passing through on chassis.
