Abstract
The invention relates to a suspension frame applicable to an independent four-drive-wheel type off-road vehicle, and belongs to the suspension frame of the independent four-drive-wheel type off-road vehicle. The structure of a bracket assembly is that: four reinforcing ribs are welded to a left fixed plate and a right fixed plate; two pieces of strengthening square steel are welded to the back surfaces of the left fixed plate and the right fixed plate; the left fixed plate and the right fixed plate are respectively welded to the two sides of an outer sleeve; the structure of an inner sleeve assembly is that: a piston rod and an oil cylinder are matched to form a hydraulic cylinder; the oil cylinder is connected with the inner sleeve through a spline; the inner sleeve is connected with an upper cover through a second bolt. The suspension frame applicable to the independent four-drive-wheel type off-road vehicle has the advantage that the structure is novel; above problems of a non-independent suspension frame are solved very well by adopting an independent four-wheel-drive suspension frame; the independent four-wheel-drive suspension frame is separately connected with a vehicle frame, and the weight is light, so that the impact to a vehicle body in a driving process is reduced very well; the position of an engine is lowered, and the gravity centre of the vehicle body is also lowered, so that the driving stability is improved very well.
Description
Technical field
The invention belongs to the suspension of the wheeled off-road vehicle of independent four-wheel, for realizing height change and turn to.
Background technology
At present, domestic off-road vehicle mostly is chassis, suspension frame structure, i.e. non-independent suspension system, the feature of this kind of suspension is that left and right suspension is connected and fixed on car body by a transverse axis, its advantage is cheap, structure is simple, but another single wheel must be caused to decline when the situation single wheel that its drawback is in driving process runs into road surface injustice rises, thus vehicle body can not do too low; In addition due to chassis height, rollover when turning to, is just very easily formed. In general through the complicated cross-country poor-performing of non-structural landform.
Summary of the invention
The present invention provides a kind of suspension being applicable to the wheeled off-road vehicle of independent four-wheel, is suspended in the problem through the complicated cross-country poor-performing of non-structural landform to solve off-road vehicle.
The technical scheme that the present invention takes is: comprise that support always becomes, outer sleeve always becomes always to become with inner sleeve,
The structure that described support always becomes is: four stiffening webs are welded on left retaining plate and right retaining plate, strengthens square steel for two and is then welded on left retaining plate and the right retaining plate back side, left retaining plate and right retaining plate are then welded in the both sides of outer sleeve respectively;
The structure that described inner sleeve always becomes is: piston rod and oil cylinder coordinate composition hydro-cylinder, and oil cylinder and inner sleeve are connected by the 2nd screw by spline joint, inner sleeve and upper cover;
The structure that described outer sleeve always becomes is: under outer sleeve, the upper surface of lid and the bottom surface laminating of inner sleeve are spacing, outer sleeve is placed on outside inner sleeve, under the bottom surface of outer sleeve and outer sleeve, the upper surface laminating of lid is spacing, cover by the 3rd screw connection under outer sleeve and outer sleeve, outer wall upper cover is placed on outside upper cover, is connected by the first screw with outer sleeve.
Described oil cylinder is for being connected with motor.
It is an advantage of the invention that novel structure, adopt independent four-wheel suspension to solve the problem of above non-independent suspension well, owing to each suspension is separate, be connected with vehicle frame separately, light weight, decrease the impact to car body in the process of moving well; Engine location reduces, and body gravity also reduces, and improves driving stability well; Jumping separately through complex road surface four wheels, it is independent of each other, effectively reduces inclination and the vibrations of car body; In addition the novel suspending bracket in the present invention can make a response the obliquity reducing vehicle frame fast to ensure personal security and Plant in good condition when wheel is subject to impacting, a suspension integrates and turns to and lifting, significantly reduce the minimum liftoff spacing of vehicle frame, thus enhance the driving stability of vehicle and the property passed through. Being adapted at the critical moment such as the anti-dangerous disaster relief runs personnel and goods and materials.

Embodiment
Comprising support always becomes A, outer sleeve always to become B always to become C with inner sleeve,
Described support always becomes the structure of A to be: four stiffening webs 9 are welded on left retaining plate 7 and right retaining plate 8, strengthens square steel 10 for two and is welded on left retaining plate 7 and right retaining plate 8 back side, left retaining plate 7 and right retaining plate 8 both sides being welded in outer sleeve 6 respectively; Thus be threaded connection with vehicle frame, this is suspension fixed part; Thus be threaded connection with vehicle frame, this is suspension fixed part;
Described inner sleeve always becomes the structure of C to be: piston rod 5 and oil cylinder 12 coordinate composition hydro-cylinder, and oil cylinder 12 and inner sleeve 11 are by spline joint, and inner sleeve 11 and upper cover 4 are connected by the 2nd screw 3;
Described outer sleeve always becomes the structure of B to be: covers the upper surface of 13 under outer sleeve and fits spacing with the bottom surface of inner sleeve 11, outer sleeve 6 is placed on outside inner sleeve 11, under the bottom surface of outer sleeve 6 and outer sleeve, the upper surface laminating of lid 13 is spacing, under outer sleeve 6 and outer sleeve, lid 13 is connected by the 3rd screw 14, outer wall upper cover 2 is placed on outside upper cover 4, is connected by the first screw 1 with outer sleeve 6;
Described oil cylinder 12 is for being connected with motor.
Such as Fig. 5, adopt four suspensions, always become the left retaining plate 7 in A and right retaining plate 8 to be bolted with vehicle frame by each support respectively, coordinate location with vehicle frame by the rectangle aperture on left retaining plate 7 and right retaining plate 8 and the angle steel on vehicle frame.
Steering procedure is turn to trapezoidal cooperation with the hole of upper cover and piston rod to drive it to rotate, thus upper cover drives inner sleeve to rotate, owing to inner sleeve and oil cylinder are spline joints, so moment of torsion is passed to oil cylinder by inner sleeve, thus oil cylinder drives vehicle wheel rotation, it is achieved Vehicular turn.
Lifting process is oil cylinder internal-filling liquid, and piston rod drives upper cover upwards to move relative to oil cylinder; Owing to upper cover and inner sleeve are threaded, and contact with outer sleeve upper cover, so power being passed to inner sleeve and outer sleeve upper cover; Outer sleeve upper cover, owing to being threaded with outer sleeve, covers still for being threaded under outer sleeve and outer sleeve, also upwards moves so covering under outer sleeve and outer sleeve thereupon. To sum up, oil cylinder moves downward relative to vehicle frame, and vice versa.
