Description
Technical field:
The utility model relates to a kind of torsion bar type independent suspension power train in vehicle application vehicle bridge, is used for the suspension of car chassis.
Background technology:
Before the utility model was made, in the prior art, the suspended portion of car chassis normally adopted two kinds of structures.A kind of is to adopt traditional leaf spring suspended structure, and it directly connects semiaxis with wheel set, and differential assembly is directly installed in the bridge bag.Though this kind structure is applied to various types of vehicles, its self-damping performance is low, can not fully absorb car vibration under steam in the mode of heat, and also has the release of energy storage.Another kind is the Pneumatic Suspension structure, and it mainly is made up of air bag, control cock and source of the gas etc.Though this structure vibration isolating effect is good more than the leaf spring vibrational structure, and the character (not transmitting of left and right cincture vibration) that independent suspension is arranged, but complex structure, make the cost height, and volume is bigger, limit field of application, be mainly used in luxury big bus and container semi-trailer at present.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; Traveling comfort in the time of improving the stability of vehicle and vehicle '; Can make vehicle bridge and driving engine when operation, not have relative motion, and can improve the transmission shaft torsion bar type independent suspension power train in vehicle application vehicle bridge in service life.
Main solution of the present utility model is achieved in that
The utility model adopts and connects outer tube 13 respectively on bridge bag 11 both sides, and outer tube 13 connects crank drive arm 17, and crank drive arm 17 is fixedly connected by output shaft 3 and wheel set 18.Differential assembly 10 is installed in the bridge bag 11, bevel gear 9 on the differential assembly 10 connects with two semiaxis 7 respectively, semiaxis 7 is installed in the inner sleeve 12, one end of semiaxis 7 and bridge bag 11 adopt antifriction-bearing box 15 supportings, the housing of the other end and crank drive arm 17 adopts antifriction-bearing box 5 supportings, mounting bar bumper 8 between inner sleeve 12 and outer tube 13, adopt plain bearing 14 supportings by bridge bag 11 1 ends, housing in the other end of inner sleeve 12 and the crank drive arm 17 connects one, input gear 4 is installed on the semiaxis 7, and output gear 1 is installed on the output shaft 3.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Captive joint (no high strength saddle Bolt Connection) between vehicle bridge and vehicle frame, vehicle bridge and driving engine do not have relative motion, the service life that can improve transmission shaft when operation; It has the character of independent suspension, and the wheel on both sides is suspension independently, mutually noninterfere, the traveling comfort in the time of can improving the stability of vehicle and vehicle '; Owing to adopted the non-metallic rods shock absorber to compare with the metal leaf spring, its self-damping performance improves greatly, and mode that can heat fully absorbs the vibration in travelling, and does not resemble the release that the metal leaf spring has energy storage, thereby has reduced noise, and its traveling comfort and air suspension are close; Its maximum vibration displacement can reach more than the 160mm, exceeds 40-500mm than leaf spring, can improve the wild nature energy that jumps of vehicle, has reduced the requirement of road pavement; The rigidity of vehicle can be along with the synchronous variation of load, and just natural frequency is more stable, and the stability of vehicle and traveling comfort do not change with the variation of load; Cost and leaf spring structure vehicle bridge are more or less the same, but well below Pneumatic Suspension, and stable and reliable for performance.
Description of drawings:
Fig. 1 is the utility model structural representation:
The specific embodiment:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of output gear 1, bearing 2, output shaft 3, input gear 4, antifriction-bearing box 5, plain bearing 6, semiaxis 7, non-metallic rods bumper 8, bevel gear 9, differential assembly 10, bridge bag 11, inner sleeve 12, outer tube 13, plain bearing 14, antifriction-bearing box 15, rocking arm casing 16, crank drive arm 17 etc.
The utility model bridge bag two limits are symmetrical structure, are respectively two cover outer tubes 13, two cover crank transmission arms 17 and two cover wheels 18 and form.Every cover outer tube 13 inner structures and every cover crank transmission arm 17 inner structures are identical.Concrete connecting mode is as follows: it mainly adopts on bridge bag 11 both sides and connects outer tube 13 respectively, and outer tube 13 connects crank drive arm 17, and crank drive arm 17 is captiveed joint with wheel set 18 by output shaft 3, and rocking arm casing 16 is installed on the outer tube 13.Being shaped as of outer tube 13 is circular, square, rhombus etc.
The utility model differential assembly 10 is contained in the bridge bag 11, the both sides of bridge bag 11 adopt outer tube 13 to pass through Bolt Connection respectively, bevel gear 9 on the differential assembly 10 connects with two semiaxis, 7 key formulas respectively, semiaxis 7 is installed in the inner sleeve 12, one end of semiaxis 7 and bridge bag 11 adopt antifriction-bearing box 15 supportings to isolate, and isolate with antifriction-bearing box 5 supportings between the housing of the other end and crank drive arm 17.Between internal and external casing 12,13 non-metallic rods bumper 8 is housed, non-metallic rods bumper 8 adopts the 3-5 root.Two ends by bridge bag 11 places, adopt plain bearing 14 supportings to isolate between the internal and external casing 12,13, adopt splined (or being welded as a whole) between the housing in the other end of inner sleeve 12 and the crank drive arm 17, input gear 4 in semiaxis 7 and the crank drive arm 17 adopts splined, input gear 4 is installed on the semiaxis 7, have on the crank drive arm 17 and adopt plain bearing 6 supportings to isolate between a shaft shoulder and the outer tube 13, be splined between output gear 1 and the output shaft 3, output gear 1 is installed on the output shaft 3, adopts the bearing supporting.The mouth of output shaft 3 is captiveed joint with wheel set 18.
Its messenger chain work is as follows during the work of torsion bar type independent suspension power train in vehicle application vehicle bridge: transmission shaft drives diff, transfer the motion to 1 semiaxis 7 by diff, semiaxis 7 drives input gear 4 rotation is passed to output gear 1, and drives output shaft 3 drive wheels 18.When travelling, because Uneven road makes the relative vehicle frame of wheel produce vibration, and drive crank drive arm 17 and inner sleeve 12 produces the angles vibration with respect to outer tube 13, make the non-metallic rods bumper 8 between inner sleeve 12 and the outer tube 13 produce elastic deformation, produce resistance of deformation simultaneously, and act on the inner sleeve 12, balance be applied to the live load on the wheel 18 and reach effectiveness in vibration suppression.
