Abstract
The utility model relates to the improvement of a suspending device of a truck, particularly a self-balance double-connection suspending frame which comprises steel plate springs which are respectively arranged on a drive axle and a bearing axle, wherein the steel plate spring on the drive axle is a main steel plate spring; the upper part of the main steel plate spring is provided with an auxiliary steel plate spring; the front end of the main steel plate spring is connected with a support frame at the fixed end on a vehicle frame; the rear end of the main steel plate spring is inserted into a sliding plate seat at the inner side of a combined support frame on the vehicle frame to form a sliding connection; the front end of the steel plate spring of the bearing axle is connected with the outer side of the combined support frame; the rear end of the steel plate spring of the bearing axle is glidingly connected with the support frame at the sliding plate end of the vehicle frame. When the bearing capacity of the drive axle and the bearing axle has large difference, the utility model ensures the reasonable load allocation of the two axles and has the advantages of simple structure, convenient maintenance and low manufacture cost.
Description
The utility model relates to the improvement of autotruck suspension gear, particularly a kind of self-balancing type duplex suspension.
At present, " balance suspension and the vertical steel spring of putting " that 6 * 4 heavy duty trucks extensively adopt passes to vehicle frame to wheel braking force and propulsive effort by 6 propelling rods, controls the running gear of jackshaft and back axle simultaneously.6 * 2 heavy-duty trucks extensively adopt be " balance oscillating arm type duplex suspension and asymmetric change rigidity steel spring technology " (patent No. into: ZL99215116.3), assurance jackshaft and back axle stress balance in a big way in.More than two kinds of suspension frame structures all be under the basic identical condition of the load-carrying capacity of jackshaft and back axle, each work can both make two axle loads obtain balance moment in theory.When the load-carrying capacity of two bridges differs big, distribute loads reasonably.
The purpose of this utility model is to provide a kind of self-balancing type duplex suspension, when drive axle differs big with carrying bridge load-carrying capacity, guarantees the rational distribute loads of two bridges, and simple in structure, easy to maintenance, can reduce the manufacturing cost and use cost of suspension greatly.
The utility model is achieved in that a kind of self-balancing type duplex suspension, comprise the steel spring that drive axle and carrying bridge are installed respectively, the steel spring of drive axle is the main steel plate spring, its top is installed with additional leaf spring, the front end of main steel plate spring is connected with fixed end support on the vehicle frame, the sectional shelf-unit sideslip panel seat on the vehicle frame is inserted in its rear end, be sliding block joint, the two ends of auxiliary spring steel spring respectively with vehicle frame on auxiliary spring support sliding block joint, be connected its rear end and vehicle frame slide plate end support sliding block joint outside the sectional shelf-unit on steel spring front end and the vehicle frame of carrying bridge.
Because the drive axle steel spring is different with the rigidity of carrying bridge steel spring, when the automobile loading is travelled, can press the design proportion distribute loads voluntarily, reach drive axle and the carrying bridge stressed effect of adjusting balance voluntarily rationally.
Automobile in motion, when drive axle is subjected to big load impacting, because this bridge steel plate rigidity is big, be out of shape little, the load-carrying capacity of bridge is strong, but self bears impact, and when the carrying bridge is subjected to big load impacting, because this bridge steel spring rigidity is little, distortion is big, and the bearing capacity of bridge is little, can produce the effect of similar balance oscillating arm, rapidly impact is delivered on the drive axle, makes two bridges reasonable distribution load within the specific limits.The use of this utility model has avoided bridge in starting with stop the axle load of moment and shift, reduced impact to vehicle bridge, the drive axle bearing load is big, adhesive ability is big, improve the power-handling capability of automobile, two additional leaf springs are linked to each other with vehicle frame by three supports, have disperseed the stressed of vehicle frame, have improved the vehicle frame strained condition.Back axle reduces automobile running resistance owing to be single tire, also makes motor turning flexible.The utility model is because no pull bar, no balance oscillating arm, so simple in structure, easy to maintenance, lower greatly suspension manufacturing cost and use cost.
