Abstract
A large-tonnage 4-point rigidly suspended platform truck has a chassis, and the front and back axles with wheels. It features that the front and back axles are linked to chassis via rigid suspension axles at 4 points (two points for front or back axle), and at least one of said rigid suspension axles has the stearing mechanism.
Description
Technical field
The present invention relates to a kind of large-tonnage flat bed transport vehicle, be meant that further the delivery tonnage is at the flat bed transport vehicle below 200 tons.
Background technology
At present, at smelter and harbour,, more and more in the dull and stereotyped vehicle needs of 100-200 ton to carrying capacity for improving operating efficiency.
For the large-tonnage transportation that surpasses 100 tons, generally adopt hydraulic pressure multi-axis balancing suspension technology both at home and abroad.This technology has following characteristics: (1) utilizes the flexible of modulated pressure oil cylinder fully to adapt to the ground-surface out-of-flat, remains loading platform level; (2) by increasing suspended axle quantity, the delivery tonnage can increase arbitrarily, at present existing 1000 tons trailer; (3) all suspended axles can be with steering hardware, and maneuverability reduces tire simultaneously and weares and teares because of slippage more.But this technology has shortcomings such as complex structure, cost height.
At smelter and harbour, have that object of transport is single, an evenness of road surface, the big characteristics of road surface carrying, therefore, hydraulic suspension adapts to the characteristics of ground-surface out-of-flat can't be given full play to, and causes certain waste economically.
Summary of the invention
The technical problem to be solved in the present invention is, deficiency at the prior art existence, propose 4 rigid suspended flat bed transport vehicles of a kind of large-tonnage, can satisfy in smelter and the field, harbour transport capacity, and reduce the manufacturing cost and the maintenance cost of transport vehicle greatly at the transportation request of 100-200 ton.
Technical solution of the present invention is, the rigid suspended flat bed transport vehicle of described large-tonnage comprises vehicle frame and wheel-mounted front axle and back axle, its technical characterictic is, all adopt rigid suspended axle to be connected between described front axle and back axle and the vehicle frame, and the position that is rigidly connected of front axle and back axle and vehicle frame is respectively two places and the four-point suspension that constitute car load are rigidly connected, and has at least one group to be the rigid suspended axle of band steering hardware in described front axle and the rigid suspended axle that back axle is connected with vehicle frame.
Below make and further specifying.
Referring to Fig. 1 and Fig. 2, the present invention includes vehicle frame 3 and wheel-mounted front axle and back axle, its technical characterstic is, all adopt rigid suspended axle to be connected between described front axle and back axle and the vehicle frame 3, and the position that is rigidly connected of front axle and back axle and vehicle frame 3 is respectively two places (the rigid suspended axle 1 of front axle as shown in Figure 2,2 and the rigid suspended axle of back axle 3,4 point of connection) four-point suspension that constitute car load are rigidly connected, have at least one group to be the rigid suspended axle 1 of band steering hardware in the rigid suspended axle of described front axle and back axle and vehicle frame 3 bonded assemblys, 2, one group that promptly forms the rigid suspended axle of front axle (as the suspended axle among Fig. 21,2) or form a group of the rigid suspended axle of back axle (as the suspended axle among Fig. 24,5) have at least one group to be the rigid suspended axle of band steering hardware in.
Referring to Fig. 1 and Fig. 2, the rigid suspended axle of another group can be the rigid suspended axle 3,4 that has the balance wheel actuation mechanism, comprises the rigid suspended structure of balance girder structure or other form.For making vehicle frame 3 that bigger elastic deformation be arranged, the distance of front and back axletree generally is advisable greater than 3.5 meters.
By embodiment illustrated in figures 1 and 2 principle of design of the present invention as can be known.Vehicle frame 3 anterior rigid suspended axles 1,2 with the band steering hardware are rigidly connected mutually; The rear portion is rigidly connected mutually with the rigid suspended axle 4,5 of band balance wheel actuation mechanism, thereby it is rigid suspended to have formed 4 of this flat bed transport vehicle.Rigid suspended axle 1,2 under the effect of flat bed transport vehicle tractive force, linear longitudinal movement or about turn to.The rigid suspended axle 1,2 of band steering hardware respectively has the lateral oscillations moving axis, and described rigid suspended axle 4,5 not only has the lateral oscillations moving axis, and has the longitudinal oscillation axle, thereby makes this car can adapt to local ground-surface out-of-flat.The pendulum angle of its oscillating axle depends on the structure (general teeter angle 12 degree, longitudinal oscillation angle 10 degree) of oscillating axle self.When axletree was on the road surface of Different Plane before and after run into, 4 rigid suspended places on the vehicle then utilized the distortion of vehicle frame and tire to adapt to a small amount of ruggedness of ground-surface.
As known from the above, the present invention is 4 rigid suspended flat bed transport vehicles of a kind of large-tonnage, can satisfy in smelter and the field, harbour carrying capacity and save the manufacturing cost and the maintenance cost of transport vehicle greatly at the transportation request of 100-200 ton, and designs simplification, dependable performance.
