Abstract
The utility model discloses a semitrailer suspension control device, comprising a frame, steel plate spring support seats, pull rod adjusting arms, a carrying air bag, a pressure sensor and a control valve, wherein the lower end of the carrying air bag is installed on the upper part of the steel plate spring support seat; the upper end of the carrying air bag is fixedly arranged on the frame; the carrying air bag is connected with an automobile circuit through the pressure sensor and the control valve; one end of each pull rod adjusting arm is connected with the frame; and the other end of each pull rod adjusting arm is connected with the steel plate spring support seat. By the adoption of the semitrailer suspension control device, in an unloaded state, multiple groups of wheels of a trailer can automatically suspend in the air; in a brake state or in a stop state, an ordinary state can be automatically recovered; the use is convenient, safe and reliable; and in the unloaded state, the simultaneous abrasion of the multiple groups of wheels is reduced, the service lives of tyres are prolonged, the oil consumption of a semitrailer is lowered, and the environmental pollution is decreased.
Description
Technical field
The utility model relates to a kind of superimposed trailer and hangs control setup, is mainly used in the suspension control of automobile superimposed trailer.
Background technology
The superimposed trailer suspension gear is one of major part of superimposed trailer, and it mainly acts on is superimposed trailer axletree movable parts and superimposed trailer crossbeam effectively and reasonably, be tied securely.The suspension gear of existing superimposed trailer is by propons steel spring and back axle steel spring and carrier base combination, and on carrier base, carrier base is installed in the middle part of steel spring to suspension holdfast with bolt by pivot knuckles.Often have disconnected spring, off-axis, the phenomenon of blowing out when existing this structure is heavily loaded, and when superimposed trailer was unloaded, a plurality of tires used simultaneously, have not only increased a plurality of Tyte Wear, and the unnecessary oil consumption and the environmental pollution that bring thus.
The utility model content
In order to solve the aforementioned problems in the prior, the purpose of this utility model is to provide a kind of superimposed trailer to hang control setup, a plurality of tires wore and tore simultaneously when this device can effectively prevent the superimposed trailer no-load run, reduce and use oil consumption, reduce environmental pollution, reduce the generation of disconnected spring, off-axis, the phenomenon of blowing out simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of superimposed trailer hangs control setup, comprise vehicle frame, spring carrier seat, pull bar adjustment arm, carrying air bag, pressure sensor, control cock, delay timer, described carrying air bag lower end is installed in the top of spring carrier seat, and the upper end of carrying air bag is fixed on the vehicle frame; Described carrying air bag is connected with automobile circuit with delay timer by pressure sensor, control cock; Described pull bar is adjusted arm one end and is connected vehicle frame, and the other end connects the spring carrier seat.
The beneficial effects of the utility model are: the superimposed trailer that uses this suspension control setup, under light condition trailer organize wheel more can be unsettled automatically, under brake and dead ship condition, can return to normal automatically, esy to use, safe and reliable, having reduced many groups tire when unloaded weares and teares simultaneously, increase tire service life, reduced superimposed trailer and used oil consumption, reduced environmental pollution.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is left view of the present utility model;
Fig. 2 is circuit block diagram of the present utility model.
Among the figure: 1, vehicle frame, 2, the spring carrier seat, 3, pull bar adjusts arm, 4, the carrying air bag, 5, pressure sensor, 6, control cock.
The specific embodiment
A kind of superimposed trailer as shown in Figure 1 and Figure 2 hangs control setup, comprise vehicle frame 1, spring carrier seat 2, pull bar adjustment arm 3, carrying air bag 4, pressure sensor 5, control cock 6, delay timer 7, described carrying air bag 4 lower ends are installed in the top of spring carrier seat 2, and the upper end of carrying air bag 4 is fixed on the vehicle frame 1; Described carrying air bag 4 is connected with automobile circuit by pressure sensor 5, control cock 6; Described pull bar is adjusted arm 3 one ends and is connected vehicle frame 1, and the other end connects spring carrier seat 2.
Described vehicle frame 1 is provided with two trailer stand 11, and it is the double helix Collapsible structure that pull bar is adjusted arm 3, and the one end is installed in trailer stand 11 bottoms, and the other end connects the bottom of spring carrier seat 2; Pull bar is adjusted arm 3 can arrange one, also can arrange many, arranges different for the back four-wheel with the back eight-wheeler.
Captive joint with vehicle frame 1 by bolt or with welding in carrying air bag 4 tops, carrying air bag 4 bottoms and spring carrier seat 2 weld or fix with U-bolt, carrying air bag 4 has the valve port of a turnover gas, this valve port is connected with control cock 6, behind the automobile starting, pressure sensor 5 spreads out of decision instruction, when confirming zero load, control cock 6 is received the inflation instruction, carrying air bag 4 is inflated to controlling valu, carrying air bag 4 pressing steel plate spring bracket seats 2 sink the steel spring that is in the spring carrier seat 2, and causing steel spring is fulcrum with trailer stand 11, the spring carrier seat that will be in the steel spring other end lifts, tire also and then lifts automatically, and pull bar is adjusted arm 3 and supported this structure, and is more stable after feasible the lifting; In the process of moving, as run into brake, the brake circuit transmits the venting instruction to control cock, 5 venting of carrying air bag, and steel spring is all got back to virgin state, and tire is got back to ground naturally, increases the reliability of brake, has reached the needed purpose of utility model.
For the superimposed trailer that the back is two groups of tires, installation method is the same, and suitable and described three groups of tire superimposed trailers remove a group of back, and installation and application is the same, in statement.
