Description
Technical field
The present invention relates to a kind of vehicle suspension system, especially a kind of suspension system for mine truck.
Background technology
Suspension system is generally used for modern power car; It flexibly couples together vehicle frame (or vehicle body) and axletree (or wheel); The impact load that absorption causes because of the irregularity of driving road surface or trailer reversing, the vibration of the bearing system that decay causes thus guarantees ride of vehicle.Existing automotive suspension system is because of the difference of factors such as its absorption characteristic, size and shape, and is of a great variety to be adapted to dissimilar vehicles.Domestic mining chassis suspension all is to adopt steel spring suspension frame structure or the many rod-type structures of coil spring at present.The steel spring suspension frame structure is because size makes that more greatly the vehicle front overhang can not be too short; Car load length is longer, and crossing ability was relatively poor when vehicle used under mine, simultaneously; Steel spring has taken most of space of vehicle frame both sides, is unfavorable for the installation requirement of mine vehicle annex; The suspension system of the many rod-type structures of coil spring, the interference of moving between the leverage that can't eliminate many leverages fully and caused, simultaneously, the suspension of the many rod-type structures of coil spring has also taken most of space of vehicle frame both sides.
Summary of the invention
The objective of the invention is to propose a kind of simple in structure, suspension system for mine truck that volume is little for the above-mentioned shortcoming that solves prior art.
The object of the invention can be realized through following technical scheme:
A kind of suspension system for mine truck; Comprise vehicle frame; Link span, lateral rod, coil spring, shock absorber, bump rubber and connection support, said link span comprises two pull bars at least, a top cross plate; A horizontal arm-tie, an end of said two pull bars is captiveed joint with the two ends of top cross plate respectively; End at said two pull bars is provided with horizontal arm-tie near the top cross plate position, and said horizontal arm-tie is parallel with top cross plate; Before and after vehicle frame inboard, be fixedly connected with between the vehicle bridge one with the vertically arranged crossbeam of vehicle frame; One end and the crossbeam of described two pull bar band top cross plate are rotationally connected through rotating shaft, and the other end is connected with the two ends of back axle respectively, make link span constitute the A font and are arranged on the vehicle frame.
Advantage of the present invention is to adopt the suspension frame structure of " A font "; Link span and cross member of frame flexibly connect; Can not only satisfy the requirement of mine vehicle, also have the high carrying capacity in very strong load-carrying capacity and the mine, in addition its rideability, maneuvering performance; This " A font " structure has been saved the space of vehicle both sides greatly, can satisfy the more installation requirement of mine vehicle annex.Novel structure of the present invention in a word, simple and reliable can satisfy the operating needs of mine vehicle, has good economic benefit again, adaptable across the mine vehicle of in all kinds mine, working.

Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Embodiment one
The structure of present embodiment is like Fig. 1, shown in 2, and a kind of suspension system for mine truck comprises vehicle frame 2, link span, lateral rod 11, variable stiffness coil spring 4, two-way cylinder type damper 5, bump rubber 3 and connection support 6.Link span is made up of 81, horizontal arm-ties 82 of 8, top cross plate of two pull bars.One end of two pull bars 8 is captiveed joint with the two ends of top cross plate 81 respectively, is welded with horizontal arm-tie 82 at an end of two pull bars 8 near top cross plate 81 positions, and horizontal arm-tie 82 is parallel with top cross plate 81; Between the inboard forward and backward vehicle bridge of vehicle frame 2, be fixedly connected with one with vehicle frame 2 vertically arranged crossbeams 1; One end and the crossbeam 1 of two pull bar 8 band top cross plate 81 are rotationally connected through adapter shaft 10, cushion rubber 9, and the other end is connected with the two ends of back axle 7 respectively, make link span constitute the A font and are arranged on the vehicle frame 2.The cross section of crossbeam 1 is the X type, and four pin of X type are captiveed joint through bolt and vehicle frame 2 are inboard respectively.Crossbeam 1 middle part has a circular port, in circular port, is fixed with cushion rubber 9 through bearing pin.On cushion rubber 9, top cross plate 81 and horizontal arm-tie 82, all have axis hole, adapter shaft 10 passes cushion rubber 9, top cross plate 81 and horizontal arm-tie 82 successively, and adapter shaft 10 two ends are respectively through the outside of bolt in cushion rubber 9 and horizontal arm-tie 82.The end that two pull bars 8 link to each other with back axle 7 has a connecting device; This connecting device comprises upper and lower locating plate that is parallel to each other and the adapter shaft that connects upper and lower locating plate; Through connecting device back axle 7 is linked to each other with link span, wherein descend locating plate to be connected with a shock absorber lower bracket 61 through bolt.In the sidewall of spring compressor 21, captive joint with shock absorber lower bracket 61 in the lower end through bolted connection in the upper end of two-way cylinder type damper 5.One end of variable stiffness coil spring 4 is socketed on the spring perch 12 that is fixed on back axle 7 one ends, and the other end is connected in the inwall of spring compressor 21, and spring compressor 21 is connected in the outside of vehicle frame 2 through bolt, has formed vertical connection the between vehicle frame 2 and the back axle 7.Connect support 6 and be fixed on the spring perch 12, an end of lateral rod 11 is hinged on through bearing pin and connects on the support 6, and the other end is articulated on the vehicle frame 2, has formed between vehicle frame 2 and the back axle 7 laterally to be connected.The skew that centnifugal force caused when in addition, lateral rod 11 can prevent owing to vehicle distortion road surface or turning.
Mining garage crosses in the journey, and link span can rotatablely move in 0 °～16 ° angles around adapter shaft 10, and to guarantee the relative motion scope of vehicle body and vehicle bridge, link span has also born the longitudinal force and the transverse force of vehicle.Variable stiffness coil spring 4 has vibration-damping function with two-way cylinder type damper 5, has improved the travelling comfort and the road-holding property of vehicle.In addition; On the inwall of spring compressor, be provided with bump rubber 3 with variable stiffness coil spring 4 junctions; Bump rubber 3 places variable stiffness coil spring 4 inside; The impulsive force that bump rubber 3 receives in the time of can reducing vehicle operating with cushion rubber 9, thus the global reliability and the stability of raising suspension system prolong the service life of system.
The present invention also is applicable to the power actuated vehicle of other type except being applicable to mine vehicle.
Except that the foregoing description, the present invention can also have other embodiments, and for example the cross section of crossbeam is except can being the H type for square.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the protection domain of requirement of the present invention.
