Abstract
A double front axle plate spring suspension system comprises a first axle, a first axle plate spring mounted on the first axle, a second axle, and a second axle plate spring mounted on the second axle, and is characterized in that the front end of the first axle spring is connected with a front bracket, and the rear end of the first axle spring is connected with one end of a first axle rocking arm through a first bridge crane; the front end of the second axle plate spring is connected with a middle bracket, and the rear end of the second axle plate spring is connected with one end of a second plate spring rocking arm through a second bridge crane; the first axle rocking arm is a falcate swinging arm rotationally mounted on the middle bracket; the second axle rocking arm is a falcate swinging arm rotationally mounted on a rear bracket, and the other end of the first axle rocking arm is connected with the other end of the second axle rocking arm through a hydraulic transmission system; and the front bracket, the middle bracket and the rear bracket are all fixed on a vehicle frame. The double front axle plate spring suspension system provided by the utility model has the benefits as follows: a novel suspension structure for balancing double front axle loads is provided, so that a double front axle vehicle is enabled to allow mutual transferring of the double front axle loads during driving, axle weights of double front axles are kept to be equal, and the service performance of the vehicle is improved.
Description
Technical field
The utility model belongs to the car construction field, is specifically related to a kind of hydro-cushion leaf spring suspension that is used for balance doube bridge load.
Background technology
For increasing the charge material amount of heavy motor vehicle, usually the propons of vehicle is made 2, every bridge assembling suspension system separately.Steel spring front end in each suspension system connects to ground by front frame, and the rear end connects to ground by hanger, after poppet, and the middle part is connected with vehicle bridge by saddle clamp.Because the suspension system of one or two bridges is separate, the quality that the car load total mass is assigned on the every bridge is unequal, causes the load of every bridge not wait, the wear on tyres inequality, and braking force does not wait; If propons is a drive axle, also can have a strong impact on the crossing ability of vehicle.
The utility model content
The purpose of this utility model provide a kind of can balance two propons leaf spring suspension systems of two weight on front axles, to solve the problem that pair weight on front axles do not wait.
For achieving the above object, of the present utility model pair of propons leaf spring suspension system comprises a bridge and a bridge plate spring (steel spring), two bridges and two bridge plate springs (steel spring) mounted thereto mounted thereto, it is characterized in that: a described bridge plate spring front end links to each other with front frame, the rear end links to each other with an end of a bridge rocking arm by a bridge crane ear; Described two bridge plate spring front ends link to each other with central support, and the rear end links to each other with an end of two bridge rocking arms by two bridge crane ears; A described bridge rocking arm is the sickleshaped swing arm that is installed in rotation on the central support, described two bridge rocking arms are the sickleshaped swing arm that is installed in rotation on the after poppet, and the other end of a described bridge rocking arm is connected by power hydraulic system with the other end of two bridge rocking arms; Wherein, described front frame, central support and after poppet all are fixed on the vehicle frame.
Preferably, hydraulic actuating cylinder and back hydraulic actuating cylinder before described power hydraulic system comprises, wherein, the piston rod of preceding hydraulic actuating cylinder is connected rotationally with the other end of a described bridge rocking arm, the piston rod of back hydraulic actuating cylinder is connected rotationally with the other end of described two bridge rocking arms, and the oil cylinder of the oil cylinder of preceding hydraulic actuating cylinder and back hydraulic actuating cylinder is communicated with by oil pipe.
The utility model is to realize hydro-cushion like this: when a load per axle increases, the vibration meeting of one bridge plate spring is delivered to an end of a bridge rocking arm by a bridge crane ear, cause the swing of a bridge rocking arm, the swing of one bridge rocking arm promotes to be connected the piston rod of its other end again, the variation of hydraulic oil in the hydraulic actuating cylinder before causing, the variation of hydraulic oil passes to the back hydraulic actuating cylinder by oil pipe, causes that the piston rod of back hydraulic actuating cylinder moves, thereby promote two bridge swing arms swing, thereby load is delivered to two bridges from a bridge.Similarly, when two load per axles increased, load also can be delivered to a bridge from two bridges like this, realized the load equalization between leaf spring (steel spring) suspension one bridge and two bridges.
The beneficial effects of the utility model are: the suspension frame structure of the two weight on front axles of a kind of later-model balance is provided, the two in motion preceding load per axles of two preceding bridge vehicles can be shifted mutually, kept two propons axle load equalizations, raising vehicle operation performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein:
1. front frame 2. 1 bridge plate springs 3. 1 bridges 4. 1 bridge crane ears 5. 1 bridge rocking arms
6. hydraulic actuating cylinder 8. oil pipes 9. 2 bridge plate springs 10. 2 bridges before the central support 7.
11. back hydraulic actuating cylinder 12. after poppets 13. 2 bridge rocking arms 14. 2 bridge crane ears
The specific embodiment
As shown in Figure 1, of the present utility model pair of propons leaf spring suspension system comprises a bridge plate spring (steel spring) 2 and two bridge plate springs (steel spring) 9.Wherein, the front end that is installed in the bridge plate spring 2 on the bridge 3 links to each other with front frame 1, and the rear end links to each other with an end of a bridge Rocker arm 5 by a bridge crane ear 4.The front end that is installed in two bridge plate springs (steel spring) 9 on two bridges 10 links to each other with central support 6, and the rear end links to each other with an end of two bridge rocking arms 13 by two bridge crane ears 14.One bridge Rocker arm 5 and two bridge rocking arms 13 are the sickleshaped swing arm, are installed in rotation on respectively on central support 6 and the after poppet 12.The other end of one bridge Rocker arm 5 is connected rotationally with the piston rod of preceding hydraulic actuating cylinder 7, and the other end of two bridge rocking arms is connected rotationally with the piston rod of back hydraulic actuating cylinder 11.The oil cylinder of the oil cylinder of preceding hydraulic actuating cylinder 7 and back hydraulic actuating cylinder 11 is communicated with by oil pipe 8.
Wherein, front frame 1, central support 6 and after poppet 12 all are fixed on the vehicle frame.
In conjunction with Fig. 1, when load increased on the bridge 3, a bridge plate spring 2 sank to causing that a bridge Rocker arm 5 rotates counterclockwise, oil cylinder 7 compressions before promoting, and hydraulic oil is pressed towards back oil cylinder 11, rotates counterclockwise thereby promote two bridge rocking arms 13, and load is delivered to two bridges 10 from a bridge 3; Equally, when two bridges, 10 loads increased, load was delivered to a bridge 3 from two bridges 10 through opposite path.Realized the load equalization between two propons leaf spring suspension one bridges and two bridges.
