Description
Technical field
The utility model relates to the suspension field of multiple-axle vehicle, specifically a kind of leaf spring staggered form balance suspension, and it is large and need goods carrying vehicle and the engineering truck of Multi-shaft support that this balance suspension is suitable for load carrying ability.
Background technology
Dependent suspension is as the preferred version of most of goods carrying vehicle and engineering truck rear overhang, and it has simple structure, low cost of manufacture, easily keeps in repair, the space that takies is little, can reduce the advantages such as car bottom plate height, commercial vehicle/comm..vehicle is applied wider; And can be implicative of each other when left and right wheels is beated, the variable quantity of tyre angle is little makes the wearing and tearing of tire little.But the longitudinal size required for leaf spring is comparatively large, current multi-axis carrying vehicle adopts four link type balance suspension, during namely the two ends of leaf spring are freely bearing in, on rear-axle casing mostly with the rear suspension of engineering truck.Like this, leaf spring is just equivalent to an equiarm trammel beam, and it is with suspension axle for fulcrum, thus when can ensure that automobile travels on rough road, each wheel can land, and in making, the vertical load mean allocation of back axle wheel.Therefore etc. but the steel spring of four link type balance suspension needs carrying two axletrees, load carrying ability is too large, so the reed being generally used for the steel spring of this form can be on the high side partially thick, arm-type balance suspension is all harder, and traveling comfort and ride comfort are all poor; And between the balance suspension of this form and vehicle frame, adopting the connection mode of single-point support, this just makes the stress of vehicle frame at this point of connection place very concentrated.
Utility model content
The purpose of this utility model is to provide a kind of leaf spring staggered form balance suspension, this balance suspension is used in the ride comfort and traveling comfort that multiple-axle vehicle improve vehicle, also reduce the eccentric wear of tire when reducing wheelbase as far as possible simultaneously, vehicle frame can be made stressed more even, and stress is relatively little.
The purpose of this utility model is achieved in that
, this leaf spring staggered form balance suspension comprises propons, back axle, front plate spring, rear leaf spring, vehicle frame, shock absorber, U-bolt, front spring hanger and rear spring hanger, it is characterized in that: it also comprises a swing arm and swing arm support, described swing arm Bracket setting is at the midway location of vehicle frame, described swing arm support is connected on vehicle frame, described swing arm and swing arm support hinged, rear end and the front spring hanger of swing arm are hinged, the described front spring hanger other end and front plate spring hinged; Front end and the rear spring hanger of swing arm are hinged, the rear spring hanger other end and rear leaf spring hinged; Described front plate spring to be connected with propons by U-bolt and to be arranged on the top of propons, and rear leaf spring to be connected with back axle by U-bolt and to be arranged on the below of back axle; The front end of front plate spring and the rear end of rear leaf spring hinged with vehicle frame respectively.
, this leaf spring staggered form balance suspension comprises propons, back axle, front plate spring, rear leaf spring, vehicle frame, shock absorber, U-bolt, front spring hanger, rear spring hanger, it is characterized in that: it also comprises a swing arm and swing arm support, described swing arm Bracket setting is at the midway location of vehicle frame, described swing arm support is connected on vehicle frame, described swing arm and swing arm support hinged, front end and the front spring hanger of swing arm are hinged, and the front spring hanger other end is hinged with front plate spring again; Rear end and the rear spring hanger of swing arm are hinged, and the rear spring hanger other end is hinged with rear leaf spring again; Described front plate spring to be connected with propons by U-bolt and to be arranged on the top of propons, and rear leaf spring to be connected with back axle by U-bolt and to be arranged on the below of back axle; The front end of front plate spring and the front end of rear leaf spring hinged with vehicle frame respectively.
Advantage of the present utility model and good effect:
1, the utility model balance suspension is applicable to load truck and engineering truck, ensureing that adjacent shaft is apart under the prerequisite do not increased, two subplate springs are used to arrange in the longitudinal cross connection of same plane, improve the force-bearing situation of steel spring, decrease the sheet number of every subplate spring, improve ride comfort and the traveling comfort of vehicle, also reducing the eccentric wear of tire simultaneously when reducing wheelbase as far as possible.
2, adopt the connection mode of supported at three point between the utility model balance suspension and vehicle frame, and four link type balance hangs the connection mode adopting single-point support between vehicle frame, the connection mode of supported at three point can make vehicle frame stressed more even, and stress is relatively little.
