Abstract
The utility model belongs to the field of automobile manufacturing, relates to a trailer longeron, and is used for solving the technical problems of insufficient strength, low bearing capacity and high load bearing surface of a traditional trailer longeron. The height at a longeron traction pin (turntable) of the trailer longeron gradually decreases from back to front, thereby reducing the height of a load bearing surface and improving the travelling stability of the trailer; the longeron height at the traction pin (turntable) gradually decreases from back to front, and the principle that the smaller the moment at the position closer to the traction pin (turntable) is, the lower the demand on the longeron strength is is smartly adopted to save the use of raw materials and improve the lightweight level of the trailer in the condition of ensuring identical load bearing strength; since the frame height at the traction pin (turntable) determines the height of the load bearing surface of the trailer, and the structure greatly decreases the frame height at the traction pin (turntable) compared with the original structure, so that the load bearing surface is simultaneously decreased to greatly improve the travelling stability of the trailer. The trailer longeron provided by the utility model is suitable for various trailers.
Description
1. technical field
The utility model belongs to automobile manufacturing field, relates to a kind of trailer longitudinal beam.
2. background technology
It is the contour structure in parallel, front and back up and down that the trailer longitudinal beam towing pin (rotating disk) of conventional confguration is located, and this structure reaches that loading strength consumable material is many and carrying surface is high, causes the running stability of car load not high.
3. summary of the invention
The utility model object is, based on researching and developing under trailer weight-saving form, solves the not high and high technical matters of carrying surface of traditional trailer longitudinal beam bearing capacity, reduce costs with weight in improve longeron bulk strength and reduce carrying surface height.
, it is characterized in that: towing pin (rotating disk) is located longeron rear side height and is greater than front height, the height of both sides, front and back, length can increase or reduce according to the difference of load capacity.
For solving prior art problem, longeron towing pin of the present utility model (rotating disk) is located to successively decrease highly from back to front, reduced carrying surface height, promoted vehicle operating stability, towing pin (rotating disk) is located longeron height and is successively decreased from back to front, has used dexterously the closer to towing pin (rotating disk) less, lower to the longeron requirement of strength principle of locating moment, guaranteeing to have saved raw-material use under same bearer requirement of strength, improved vehicle weight-saving level; Because towing pin (rotating disk) is located the height that chassis frame height determines vehicle carrying surface, this structure makes towing pin (rotating disk) locate chassis frame height greatly to reduce than original design, thereby carrying surface is reduced simultaneously, has greatly improved the stability of Vehicle Driving Cycle.
4. accompanying drawing explanation
Fig. 1 is the utility model longeron lateral plan
Fig. 2 is conventional confguration longeron lateral plan
5. the specific embodiment
According to longeron lateral plan (Fig. 1) the utility model trailer longitudinal beam, successively decreased by backward front height in towing pin 1 place, improved the whole weight capacity of longeron and vehicle operating stability when reducing carrying height, own wt.
Claims (1)
1. a trailer longitudinal beam, is characterized in that: towing pin rotating disk place longeron rear side height is greater than front height.
