A kind of low floor CNG bus that my company produces, for reducing the use cost of user, meet user to walkway clearance requirement, front suspension have employed portal frame type (large drop bridge low between the senior middle school of two) steel spring structure, described portal frame type supporting plate mounting hole is that air spring suspension is special, and its transverse width is little, directly can not install steel spring, rebound must be adopted to install, the minimum turning radius≤12M of car load must be met simultaneously; In addition, CNG gas cylinder is arranged on directly over roof, causes front suspension weightening finish 1000KG.
For improving the anti-roll capability of car load, front stabilizer bar must be installed, but portal frame type structure comparison is special, arranges that front stabilizer bar can produce movement interference with steering drag link in the usual way.
(3) utility model content:
For this reason, the utility model proposes one can to meet design requirement the portal frame type low floor bus steel spring front suspension structure of (install steel spring and front stabilizer bar and meet car load minimum turning radius≤12M).
The utility model portal frame type low floor bus steel spring front suspension structure, its technical scheme comprises portal frame type front suspension, difference also comprises rebound and U-shaped front stabilizer bar, described rebound is installed respectively on the air bellow support attachment face of portal frame type front suspension arranged on left and right sides, left and right steel spring to be placed in respectively on left and right rebound and to compress with spring bearer plate, and the lower end of the left and right vibration damper assembly plate body respectively at left and right rebound rear outside is installed; Described front stabilizer bar is located between the left and right steel spring of portal frame type front suspension bottom front, and the rear end of the left and right body of rod of front stabilizer bar is connected to by suspension rod assembly on boom support that left and right rebound front inner plate body is arranged.
In said structure, expanded the horizontal installation site of left and right steel spring by left and right rebound, designed by the inner shrinking structure (spacing of the left and right body of rod of front stabilizer bar is little) of front stabilizer bar low level, effectively avoid steering drag link.
The structure that the utility model is installed bottom front vehicle frame is: the forward and backward two ends of left and right steel spring are installed in the left and right longeron side of front vehicle frame respectively by steel spring mount pad; The upper end of left and right vibration damper assembly is installed respectively at below front compartment wheel cover; The horizontal body of rod in front end of front stabilizer bar is installed bottom front vehicle frame by stabilizing rod support.
The beneficial effects of the utility model:
1, the utility model portal frame type low floor bus steel spring front suspension structure is simple, and cost is low, highly versatile, solves the problem directly can not installing steel spring on portal frame type front suspension, is applicable to different automobile types.
2, the utility model structure movement interference that can effectively prevent suspension rod assembly and produce between front stabilizer bar and front vehicle frame, anti-roll capability is strong, and floor compartment can be avoided protruding, improves commonality and travelling comfort that front stabilizer bar arranges, easy to installation and maintenance.
