Abstract
The utility model relates to the improvement of a stabilizer bar structure of a full air front suspension frame of an automobile steering bridge. A lateral stabilizer bar 10 presents a U shape, and the U-shaped opening faces front. Both ends of the lateral stabilizer bar 10 are respectively movably connected with the lower end of a balance plate 11 of the stabilizer bar, and both ends of the U-shaped bottom of the stabilizer bar are rotationally connected with connecting plates 9 of the stabilizer bar. The upper end of the balance plate 11 of the stabilizer bar is movably connected to a hanging seat 13 of the stabilizer bar, and the two connecting plates 9 of the stabilizer bar on both sides are fixedly connected with a lower supporting base 2 of a gas bag. Because the utility model adopts the structure that the two connection plates 9 of the stabilizer bar on both sides are fixedly connected with the lower supporting base 2 of the gas bag, and both ends of the U-shaped bottom of the lateral stabilizer bar are rotationally connected with the connection plates 9 of the stabilizer bar, the U-shaped bottom of the lateral stabilizer bar can be adjusted correspondingly to symmetrical planes of the whole suspension frame, does not pursue strict axial symmetry and can move appropriately to left and right for requirements of assembly. The utility model makes assembly more conveniently, and is applicable to the medium-sized passenger vehicles.
Description
Technical field
The utility model is to be applied to the front overhang shelf structure, the improvement of the full air front suspension of particularly a kind of steering axle of automobile structure.
Background technology
The automotive suspension parts are divided into leaf spring suspension and air suspension two big classes at present, and wherein air suspension can be divided into full air suspension and compound suspension again.Spring type suspension front suspension structure is made up of chassis side rail, crossbeam, steel spring and support thereof, shock absorber and upper and lower support thereof, vertical load is all born by leaf spring, so the vibration isolation of system is poor, ride comfort is bad, and empty, at full load overall height changes greatly, and promptly boarding is poor.Combined type air front suspension structure is made up of chassis side rail, crossbeam, steel spring and support thereof, air bag and upper and lower bearing thereof, shock absorber and upper and lower support thereof.The vertical load of automobile is carried jointly by leaf spring and air bag, and it is suspended on vibration isolation, the ride comfort than leaf spring and increases, but also has gap with the commercial vehicle/comm..vehicle standard of higher one-level, and its anti-roll capability of spring type suspension descends relatively.
The existing full air front suspension of a kind of steering axle of automobile structure, the two ends of its U-shaped stabilizer rod are hinged on the inboard of left and right air bag undersetting, and its middle part connects to ground by two stable suspension rods; The U-shaped opening of stabilizer rod is (is preceding with vehicle traveling direction) towards the back.Because the air bag undersetting captives joint with propons, and the hole of U-shaped stabilizer rod end must be connected with the connecting bore on the air bag undersetting, and this just requires propons and air bag undersetting connecting bore size very accurate.If the mounting hole on the propons is processed with error, when perhaps there was foundry defect in the air bag undersetting, the phenomenon adorning will appear in U type stabilizer rod both ends, brings difficulty to assembling.
Summary of the invention
The utility model is to overcome the shortcoming that above-mentioned prior art exists, and the full air front suspension of a kind of improved steering axle of automobile structure is provided.
The utility model has adopted following technical proposal to solve its technical matters: the full air front suspension of a kind of steering axle of automobile structure, comprise chassis side rail, cross member of frame, propons, air bag undersetting, air bag upper bracket, bumper, it is characterized in that, one Panhard rod is the U type, and U type opening is towards the front; The Panhard rod two ends flexibly connect with stabilizer rod balance plate lower end respectively, and the U-bottom portion two ends and the stabilizer rod connecting panel of Panhard rod are rotationally connected; Stabilizer rod balance plate upper end is movably connected on the stabilizer rod flap seat; Both sides two stabilizer rod connecting panels are captiveed joint with the air bag undersetting.
The stabilizer rod flap seat can be fixedly connected on the cross member of frame; The U-bottom portion two ends of Panhard rod can be rotationally connected by rubber shaft bearing and stabilizer rod connecting panel respectively.
The propons two ends are captive joint both sides air bag undersetting respectively; Captiveing joint with both sides air bag undersetting upper end respectively in the bottom of two the air bag assemblies in both sides, captives joint with both sides air bag upper bracket respectively in its top; Both sides air bag upper bracket is fixedly connected on the chassis side rail outside; Each two longitudinal rod of both sides, longitudinal rod one end of every side flexibly connects by bulb with both sides air bag undersetting respectively, and the other end flexibly connects by bulb with the forward thrust shaft bar respectively; Both sides two forward thrust shaft bars are fixedly connected on the anterior outside of chassis side rail respectively; One lateral rod, one end is movably connected on the air bag undersetting by bulb, and the other end is movably connected on the crossbeam by bulb; The two ends of crossbeam are fixedly connected on the bottom of chassis side rail.
Captiveing joint with both sides air bag upper bracket respectively in two bumpers upper end, both sides, captives joint with both sides air bag undersetting respectively in the lower end.
Levelling valve is fixedly connected on the crossbeam by upper bracket; Levelling valve adjust bar assembly top and levelling valve flexibly connect, and the bottom is fixedly connected on the lower bracket; Lower bracket is fixedly connected on the propons.
The utility model is owing to adopted both sides two stabilizer rod connecting panels to captive joint with the air bag undersetting, the structure that the U-bottom portion two ends of Panhard rod and stabilizer rod connecting panel are rotationally connected, the U-bottom portion of Panhard rod can regulate with respect to the plane of symmetry of whole suspension, do not pursue strict rotational symmetry, can accomplish for the needs that assemble sway suitably.The utility model makes assembling more convenient.The utility model had both kept road-holding property, had improved ride comfort, had overcome the weakness of combined type air suspension anti-roll capability difference again, had improved roll rate simultaneously, and its anti-roll capability is suitable with the leaf spring suspension, makes the vehicle safety in travelling obtain guarantee.The utility model is applicable to medium bus.
