Description
Technical field
The utility model relates to a kind of rear suspension system, particularly a kind of engineering truck rear suspension system.
Background technology
Suspension is exactly bumper in vehicle, connect the part having spring and damping bucket between wheel and car body, mainly absorb ground and pass to jolting in car, suspension mainly contains following several: independent suspension system, multi link hang, MacPherson type hangs, pulls arm-type suspension.Engineering truck load capacity is large, therefore suspension requires that the weight demands of carrying is higher, general main employing hanging and spring cooperatively interact and carry out damping, such structure technology is ripe, easy to use, but due to the setting of intermediate connecting rod, thus take larger one-tenth intracorporeal space, thus make in adult, to utilize space to reduce, increase the volume of the entirety of car body, the lightweight of inconvenience and car body and operation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of engineering truck rear suspension system, and it carries out damping by two groups of hydraulic rams to the wheel arranged separately, thus without the need to connecting rod, takes up room little, easy to operate.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of engineering truck rear suspension system, it is characterized in that: it comprises two groups of hydraulic rams, connected pipes, castellated shaft, tire and wheel seats, described tyre rotation is arranged on wheel seat, castellated shaft is vertically arranged and lower end is fixed on the upside of wheel seat, described hydraulic ram comprises cylinder body, piston and piston rod, described piston is arranged in cylinder body, piston rod one end is fixed on the other end on piston and is fixedly connected with castellated shaft upper end, cylinder body upper end has oil pipe mouth, and described connected pipes two ends are connected with the oil pipe mouth of two groups of hydraulic rams.
Further, described two groups of hydraulic rams are fixed on vehicle body by attachment flange, described vehicle body are provided with the vertical chute mated with wheel seat, and described wheel seat to be arranged in vertical chute and can vertically to slide up and down.
Further, described castellated shaft is provided with rotating base, rotating base is connected by fluid motor-driven with HM Hydraulic Motor, and castellated shaft to be arranged in the circular hole in the middle of rotating base and can to rotate with rotating base under rotating base drives.
Further, described rotating base is fixed on vehicle body, and castellated shaft to be arranged in rotating base and vertically can to slide up and down in rotating base.
The utility model compared with prior art, have the following advantages and effect: engineering truck rear suspension system structure is simple, cheap for manufacturing cost, the hydraulic ram connected by connected pipes by two groups is arranged on going out to take turns to coordinate and carry out damping on wheel seat with independent rotation, when running into obstacle, stressed thus the squeezed fluid compressing cylinder of single wheel, pressure is transferred in the hydraulic ram of opposite side by connected pipes to be shared, thus make hydraulic ram compression shock absorption respond well, such structure does not need connecting rod, thus saved larger space, thus increase the degree of utilization of engineering interior space.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of engineering truck rear suspension system of the present utility model.
Fig. 2 is the cutaway view of a kind of engineering truck rear suspension system of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
As shown in the figure, a kind of engineering truck rear suspension system of the present utility model comprises two groups of hydraulic rams 1, connected pipes 2, castellated shaft 3, tire 4 and wheel seat 5, tire 4 rotates and is arranged on wheel seat 5, castellated shaft 3 vertically arranges and lower end is fixed on the upside of wheel seat 5, hydraulic ram 1 comprises cylinder body 6, piston 7 and piston rod 8, piston 7 is arranged in cylinder body 6, piston rod 8 one end is fixed on the other end on piston 7 and is fixedly connected with castellated shaft 3 upper end, cylinder body 6 upper end has oil pipe mouth, and connected pipes 2 two ends are connected with the oil pipe mouth of two groups of hydraulic rams 1.By such structure, tire 4 rotates and is arranged on wheel seat 5, then wheel seat 5 upper end is connected with the piston rod 8 of hydraulic ram 1 by castellated shaft 3, like this when the tire 4 of side runs into obstacle time, the pressure that tire 4 is subject to strengthens, thus the hydraulic ram 1 of compression side, hydraulic ram 1 is increased by compressed pressure and is delivered in the hydraulic ram 1 of opposite side by connected pipes 2 by unnecessary oil, bear pressure by such mode two hydraulic rams 1 simultaneously, reduce the requirement of hydraulic ram 1 and use convenient, damping effect is better.And by such post-suspension structure, do not need intermediate connecting rod, thus saved a large amount of spaces in the middle of engineering truck, more thing can be set and make engineering truck internal arrangement more compact, reduce engineering truck vehicle body volume on the whole.
Two groups of hydraulic rams 1 are fixed on vehicle body 10 by attachment flange 9, vehicle body 10 are provided with the vertical chute mated with wheel seat 5, and wheel seat 5 to be arranged in vertical chute and can vertically to slide up and down.By such structure, restriction wheel seat 5 slides up and down track, thus makes stressed of wheel seat 5 be vertical direction, decreases the stress of wheel seat 5 horizontal direction, thus extends the service life of wheel seat 5.
Castellated shaft 3 is provided with rotating base 11, rotating base 11 is connected with HM Hydraulic Motor 12 and is driven by HM Hydraulic Motor 12, and castellated shaft 3 to be arranged in the circular hole in the middle of rotating base 11 and can to rotate with rotating base under rotating base 11 drives.Rotating base 11 is fixed on vehicle body 10, and castellated shaft 3 to be arranged in rotating base 11 and vertically can to slide up and down in rotating base 11.By such structure, castellated shaft 3 under the driving of rotating base 11 can 360 degree rotate arbitrarily, thus each tire 4 drives separately, engineering truck is travelled more flexible, and do not need the parts such as middle axle drive shaft equally, coordinate with rear suspension system, thus by completely out vacant for engineering truck middle chassis lower side space, thus can miscellaneous part be set, substantially increase the degree of utilization in space, reduce engineering truck car load volume, achieve lightweight, reduce cost.
Above content described in this specification sheets is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of the utility model specification sheets or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
