Abstract
The utility model discloses an automobile axle with a separation device. The automobile axle with the separation device comprises an axle tube, wheel cores, a differential mechanism and hydraulic motors, wherein the wheel cores are arranged on the axle tube, and the axle tube is provided with an air cylinder control switch. The automobile axle with the separation device is characterized in that the axle tube is provide with at least one lifting device used for lifting and putting down the whole automobile axle; the power mechanism of the lifting device is a hydraulic lifter or a pneumatic lifter; the differential mechanism comprises a differential lock, a reduction gear group and an inter-axle differential assembly; the lifting device consists of two automobile axle lifting air bags installed on two ends of the axle tube, and an air bag installed in the middle of an inter-wheel automobile frame. When a drive axle and the hydraulic motor need to be subjected to separation and reunion in the automobile driving process, after the automobile axle is lifted by the lifting device, a shifting fork is operated to control the air cylinder to realize manual separation and reunion, separation and reunion can be simply and reliably carried out, torsion is big, and parking switching is omitted.
Description
Technical field
The utility model relates to axletree and component technology field thereof, relates in particular to a kind of automotive axle with disengagement gear.
Background technology
Automotive axle, claims again axletree, is to be connected with vehicle frame or self-supporting body by suspension that its two ends installing wheel is used for transmitting motive power and the moment thereof between vehicle frame or self-supporting body and wheel.
Traditional drive axle or trailer vehicle bridge all rely on the friction of brake facing to produce braking, when long slope or heavy duty, easily cause brake overheated cause brake failure or braking distance elongated.Sort this problem out need to be on drive axle or is had and in the trailer vehicle bridge of diff, install HM Hydraulic Motor additional and make auxiliary braking.In prior art, the separate mode that is connected of vehicle bridge and change-speed box, the same with the differential locking-device of vehicle bridge, mainly contain two kinds of electronics clutch and Manual mechanical clutches.Generally speaking, electronics clutch has flexibly, advantage easily, but its torsion is little, fragile, reliability is lower slightly; Although and Manual mechanical clutch is simple and reliable, torsion is large, must stops and switch.
Summary of the invention
The purpose of this utility model is to provide a kind of vehicle bridge with disengagement gear, solves the separation and connectivity problem of automobile drive axle and change-speed box, HM Hydraulic Motor, reaches that clutch is simple and reliable, torsion is large, the object that need not stop and switch again.
The utility model adopts following technical scheme.
With an automotive axle for disengagement gear, comprising: bridge tube, is arranged on the core wheel on bridge tube, diff, and HM Hydraulic Motor arrange inflator master cock on bridge tube, it is characterized in that, described bridge tube is provided with at least one is used for mentioning, puts down the lifting device of whole vehicle bridge; The actuating unit of described lifting device is fluid pressure type lifting machine or pneumatic type lifting machine; Described diff comprises: differential locking-device, train of reduction gears and interaxle differential assembly.
Described lifting device is comprised of the air bag that is arranged on central frame beam between two axle lift air bags at bridge tube two ends and wheel.
As further illustrating of such scheme, described lifting device is connected with the control system of operator's compartment, and described control system is provided with the lifting indicator lamp for showing lifting state.
As a kind of preferred embodiment, described bridge tube is overall d-axis.
Compared with prior art, a kind of automotive axle with disengagement gear that the utility model provides, by install lifting device additional on bridge tube, when connecting when separation drive axle or the trailer vehicle bridge that has a diff and HM Hydraulic Motor, by operation lifting device, lift vehicle bridge, operate again inflator master cock fork, can complete and connect or separate; The switching of need not stopping, practicality is good.
Accompanying drawing explanation
Figure 1 shows that the structural representation of a kind of automotive axle with disengagement gear that the utility model provides;
Figure 2 shows that the view after a kind of trailer vehicle bridge with disengagement gear that the utility model provides is by lifting.
Description of reference numerals:
1, bridge tube 2, core wheel 3, inflator master cock 4, lifting vehicle bridge air bag 5, semiaxis
6, HM Hydraulic Motor.
The specific embodiment
For further setting forth essence of the present utility model, by reference to the accompanying drawings the specific embodiment of the present utility model is described as follows.
As shown in Figure 1, a kind of automotive axle with disengagement gear, comprising: bridge tube 1, be arranged on the core wheel 2 on bridge tube 1, inflator master cock 3, diff, promote vehicle bridge air bag 4, be arranged on central frame beam air bag between the wheel on bridge tube top, two of left and right semiaxis 5 and HM Hydraulic Motor 6.In other embodiments, described lifting vehicle bridge air bag substitutes with hydraulic lifting device, is not limited to the present embodiment.
In the present embodiment, preferably bridge tube 1 is overall d-axis, to strengthen the integrated carrying amount of vehicle bridge.Described diff comprises: differential locking-device, and train of reduction gears and inflator master cock 3 and interaxle differential assembly, this differential assembly comprises differential and the box of tricks of die-offing between wheel.Described inflator master cock 3 is arranged in interaxle differential assembly, between the semiaxis 5 of two of left and right, is the switch for controlling diff fork, and in figure, fork inclination (shown in black solid line) is off status, and vertical bending (shown in grey dotted line) is out state.
In automobile actual travel process, differential locking-device is not worked, and when skidding appears in a certain wheel, promotes vehicle bridge air bag 4 and mentions vehicle bridge, and inflator master cock 3 is ordered about differential locking-device work, now vehicle bridge is lowerd; Treat that automotive safety rolls muddy road away from or vehicle bridge is mentioned in descending section again, inflator master cock 3 is ordered about differential locking-device and is quit work, then vehicle bridge is lowerd, automobile normal running.In like manner, when needs are done clutch to trailer vehicle bridge and HM Hydraulic Motor 6, by lifting device, lift vehicle bridge, as shown in Figure 2; Operation is controlled inflator switch and can be realized manual clutch again, and practicality is good.
Especially, judge the concrete lifting state of vehicle bridge for convenience of chaufeur, described lifting vehicle bridge air bag is connected with the control system of operator's compartment, and described control system is provided with the lifting indicator lamp for showing lifting state.
Although the above specific embodiment has been described in detail essence of the present utility model, can not to protection domain of the present utility model, limit with this.In every case according to the essence of the utility model, the simple modifications of doing, modification or equivalent transformation, within all dropping on claim protection domain of the present utility model.
