Abstract
The utility model relates to an articulated chassis, pertaining to the field of engineering machineries and technologies for manufacturing of engineering transport vehicles, characterized in that: the articulation point is positioned above the axle case of the front frame of the traction head; a coaxial pin shaft is provided lengthways above the front frame axle case to connect front frame of the traction head with articulating parts; freedom of motion for lengthways rotation is provided between front frame of the traction head and the articulating parts; a pin shaft vertically coaxial is provided on the articulating parts to connect the articulating parts with the trailer frame; freedom of motion for rotation in the direction of the plummet shaft; a shock absorber is provided respectively between the front frame and the articulating parts and at two sides of the pin shaft; a pair of steering cylinders are provided symmetrically between the articulating parts and the trailer frame, and the steering cylinders are fixed on the articulating parts by the pin shaft. The utility model has a small turning radius, with excellent mechanical damping characteristics and improved capability for turning and shock absorption, and the damping force has a strong sensitivity over compression speed.
Description
One, technical field
The utility model relates to a kind of hinged chassis, belongs to construction machinery industry, engineering transportation vehicle manufacturing technology field.
Two, technical background
Conventional vehicles all is a rigid-frame, just has only a vehicle frame.Realize turning to of vehicle by the mode that makes wheel flutter deflection.Because the restriction of structure, the deflection angle of wheel flutter is general≤and 40 °.Therefore, the Turning radius of vehicle is bigger.Especially some lengthening vehicles, Turning radius is just bigger.
Along with the development of technology, articulated chassis has appearred again.This chassis is made up of former and later two vehicle frames.The centre couples together by articulated section.Drive forward and backward vehicle frame by steering cylinder and form certain included angle, realize turning to of vehicle.Since only couple together between forward and backward vehicle frame by articulated section, in the vehicle ' process, the coordination and the coupling of the relation of lacking exercise between forward and backward vehicle frame.There is defective in the dynamics of whole chassis.The front and back two parts on chassis lack the buffer shock-absorbing link of twisting in the process of moving.Three, summary of the invention
Three, summary of the invention
The technical matters of the utility model technology is: the Turning radius of vehicle is little, has significant compression speed sensivity, has improved the buffer shock-absorbing intensity of the twisting of vehicle ' process.
Technical solution: hinge-point is arranged on the top of drawing head front truck bridge formation case, vertical coaxial two bearing pins that are provided with in front truck bridge formation case top, drawing head front vehicle frame and articulated section are coupled together, drawing head front vehicle frame and articulated section are provided with the degree of freedom of vertical rotation, vertical two coaxial bearing pins are set on articulated section, with articulated section with after pull vehicle frame and couple together, articulated section sets up the degree of freedom that the axle of the plummet direction is rotated with the back towed vehicle; Between front vehicle frame and the articulated section, the both sides of the bearing pin of vertical coaxial setting respectively are provided with a bumper; Articulated section and after pull and be symmetrical set a pair of steering cylinder between vehicle frame, be fixed on the articulated section by bearing pin.
The utility model adopts high-order pivotally attached mode, and promptly hinge-point is chosen in the top that front truck is built bridge; Because the utility model is between front vehicle frame and articulated section, a bumper is respectively arranged in the both sides of the bearing pin of vertical coaxial setting, realizes the torsion damping function between forward and backward vehicle frame.This bumper is a kind of bumper of oil gas combination, and its resistance has the characteristic of responsive to speed; The a pair of steering cylinder that is symmetrically arranged between vehicle frame in articulated section and back is realized the function that turns between forward and backward vehicle frame.
Four, description of drawings:
Fig. 1 is the utility model birds-eye view;
Fig. 2 is the utility model lateral plan;
Fig. 3 is local figure for the utility model is articulated and connected;
Fig. 4 is that the A of Fig. 3 is to figure;
Fig. 5 is that the B of Fig. 3 is to figure;
Five, the specific embodiment
The utility model adopts high-order pivotally attached mode, have ± 90 ° of deflection angles, be that hinge-point is chosen in the top that drawing head 1 front truck is built bridge, 2 bearing pins 6,7 by the vertical coaxial arrangement in front truck bridge formation case top couple together drawing head 1 front vehicle frame and articulated section 3.Drawing head 1 front vehicle frame and articulated section 3 only keep the degree of freedom that vertically rotates.On articulated section 3, arrange vertical coaxial two bearing pins 4,5, with articulated section 3 with after pull 2 vehicle frames and couple together.Articulated section 3 with after pull 2 vehicle frames and only keep the degree of freedom that the axle of the plummet direction is rotated.
Between drawing head 1 front vehicle frame and articulated section 3, respectively arrange a bumper 8 in the both sides of adapter shaft 6,7, realize drawing head 1 front vehicle frame and after pull torsion damping function between 2 vehicle frames.This bumper 8 is bumpers of a kind of oil gas combination, and its resistance has the characteristic of responsive to speed.
Articulated section 3 and after pull a pair of steering cylinder 9 that is symmetrically arranged between 2 vehicle frames, realize drawing head 1 front vehicle frame, after pull the function that turns between 2 vehicle frames.
4 * 2 engine behind front wheel before drivings; Forward and backward bridge respectively with forward and backward vehicle frame stiff assembly; Wide basic without inner tube type off-the-road tyre.
