Description
Technical field
The utility model relates to a kind of suspension, especially relates to the air bag suspension back vehicle bridge device that uses on a kind of passenger vehicle.
Background technology
The BFs that adopt of passenger vehicle suspension at present more, and adopt the passenger vehicle travelling comfort of BF relatively poor relatively.Undoubtedly, passenger vehicle adopts PS Pneumatic Suspension to can greatly improve the travelling comfort of high-grade passenger vehicle.But present PS Pneumatic Suspension all comes from import, and price is high, and past-sale service is difficult, has had a strong impact on PS Pneumatic Suspension and on high-grade passenger vehicle, has promoted and use.The key of 6 air bag PS Pneumatic Suspensions of exploitation production domesticization is how suspension is fixed on the vehicle bridge body, comprises that the C ellbeam is connected with the vehicle bridge body with fixing, the propelling rod of vehicle bridge body.Particularly the C ellbeam takes up room greatly, and how cloth deposits compressed air brake cylinder and automatic clearance adjuster becomes the design-calculated difficult point on the vehicle bridge body.
The utility model content
The purpose of the utility model is exactly to provide a kind of rationally distributed in order to overcome the defective that above-mentioned prior art exists, and is functional, the air bag suspension back vehicle bridge device that uses on the lower passenger vehicle of price.
The purpose of the utility model can realize through following technical scheme:
The air bag suspension back vehicle bridge device that uses on a kind of passenger vehicle; It is characterized in that; This vehicle bridge device comprises vehicle bridge body, adapted seat, stabilizer rod, C ellbeam, propelling rod bearing, propelling rod, compressed air brake cylinder support, camshaft, compressed air brake cylinder, adjusting arm and shock absorber, and described adapted seat has two, is welded to connect in the left and right sides, square-section of vehicle bridge body and places the steel spring place; Described stabilizer rod is connected with adapted seat; Described C ellbeam is through being bolted on the adapted seat, and the two ends of this C ellbeam are provided with shock absorber and air bag, and described propelling rod bearing is welded on the top of the axle housing at vehicle bridge body middle part; Described propelling rod is connected with the propelling rod bearing; Described compressed air brake cylinder props up the inboard that is erected at the C ellbeam, and described camshaft is connected with the compressed air brake cylinder support through oscillating bearing, and described compressed air brake cylinder connects the compressed air brake cylinder support through adjusting arm.
Described compressed air brake cylinder support is welded on the axle housing.
Described adjusting arm is that propons uses band to turn the automatic clearance adjuster of head.
Described propelling rod bearing is realized the installation and the location of vehicle bridge body and vehicle frame through oblique thrust bar and vertical propelling rod.
The error that described oscillating bearing utilizes spherical aligning principle compensation welding to cause.
Compared with prior art, the utlity model has following advantage:
1. adopt into oscillating bearing and replace camshaft support, utilize the spherical aligning principle compensation of oscillating bearing to weld the error that causes, guaranteed that camshaft rotates freely, gets a promotion the performance of PS Pneumatic Suspension.
2. through using the utility model, high-grade passenger vehicle can adopt 6 air bag air suspensions of production domesticization, has improved the traveling comfort of passenger vehicle, greatly reduces the price of air suspension passenger vehicle, has strengthened the competitive power of passenger vehicle.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of vehicle bridge body.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
A kind of passenger vehicle with 6 air bag PS Pneumatic Suspensions after vehicle bridge; Its structure is like Fig. 1, shown in 2; It is characterized in that, comprise vehicle bridge body 1, left adapted seat 2, propelling rod bearing 3, right adapted seat 4, axle housing 5, compressed air brake cylinder 6, adjusting arm 7, compressed air brake cylinder support 8, oscillating bearing 9, camshaft 10, shock absorber 11, C ellbeam 12, propelling rod 13, air bag 14, stabilizer rod 15, the square-section of vehicle bridge body 1 was placed the welding left and right sides, steel spring place originally and was provided with left adapted seat 2 and right adapted seat 4; Stabilizer rod 15 is connected with right adapted seat 4 with left adapted seat 2 respectively; On left adapted seat 2 and right adapted seat 4, propelling rod bearing 3 is welded on axle housing 5 tops at vehicle bridge body 1 middle part to C ellbeam 12 through bolt, and propelling rod 13 is connected with propelling rod bearing 3; Propelling rod bearing 3 is realized the installation and the location of vehicle bridge body and vehicle frame through oblique thrust bar and vertical propelling rod; Compressed air brake cylinder support 8 is placed on the inboard of C ellbeam 12, adopts welding manner to be fixed on the axle housing 6, and camshaft 10 links to each other with compressed air brake cylinder support 8 through oscillating bearing 9; Compressed air brake cylinder 8 is connected with compressed air brake cylinder support 8 through adjusting arm 7, and shock absorber 11 fixes on C ellbeam 12 two ends with air bag solid 14.
Because it is bigger that C ellbeam 12 takes up room, can't be as the steel spring vehicle bridge on axle housing 5 the fixing compressed air brake cylinder support 8 of the method for bolt together.Therefore adopt the mode of welding, compressed air brake cylinder support 8 is fixed on the axle housing 5.But welding method can't be adjusted support, causes the camshaft support on the support also can't adjust, and it is not smooth that camshaft 10 is rotated, and makes brake failure.For avoiding this situation to occur, adopt oscillating bearing 9 to replace camshaft support, utilize the spherical aligning principle compensation of oscillating bearing 9 to weld the error that causes, guaranteed that camshaft rotates freely, gets a promotion the performance of PS Pneumatic Suspension.In addition, in order to dodge suspension, compressed air brake cylinder 6 needs to move toward the bridge center as far as possible.For this reason, the band that adjusting arm 7 has adopted propons to use turns the automatic clearance adjuster of head, has well solved this problem.
