Tow truck structure overall layout design
Tow truck is modified special truck with lifting, wrecker and drag equipments for broken cars and trucks towing. Tow trucks layout is critical tow truck designing process. Following is several tow truck overall layout designing ways.
New tow truck development process.
Tow truck market research and feasibility analysis
Tow truck market demand is tow truck development driving force and success insurance. So deep customer requirement deep researching such as tow truck performance, operation requirement and quantity requirement etc is needed. Generally, heavy, multi-function and humanly tow trucks are more welcomed.
Tow truck design technology
Tow truck designing main task is identifying tow truck performance parameter, choosing suitable truck chassis, providing components controlling parameter and designing requirement, designing all parts suitable layout and calculating performance.
A. Main tows truck performance parameter determination.
Tow trucks main performance parameter is towing performance. That is, through dump truck market research and statistical analysis determine dump truck main specific performance. Such as: rated tow weight, rated loading weight, rated lifting weight etc.
B. Tow truck chassis choice
Tow truck chassis performance determine tow truck basic performance, maximizing tow truck chassis ability and using suitable tow truck chassis is the key in tow truck choice. Tow truck is used on road normally, and mainly used chasses are Class II truck chassis. Main chassis maker include FAW, Dongfeng, Jiangling, IVECO, Steyr, Isuzu etc.
C. Tow truck general layout drawing
General layout should has special tow device position, dimension, PTO and power transmission device model and dimension. And modified chassis should mark modified location detail size.
D. Tow trucks overall performance parameters and calculation
After tow truck general layout is confirmed, we can calculate axle loader distribution and special equipment performance requirement, and revising general layout according calculated result.
E. Assembly parts designing and component designing
According general tow truck layout, designer develop each assembly set and part. After assembly first designing completed, designer should further revise general layout and make it more suitable.
3. New tow truck trial production
Two tow trucks trail production is a must for trail production normally. After tow truck designing completed, technical crate manufacturing process chart according designing drawing for production. Technical personnel should participate in and cooperate with new tow trucks trial production, and solve exposed designing, technical problems during trail production. Tow truck trial production is to confirm general designing corrective and verification process.
4. New tow truck identification
After tow truck trail production, new tow truck must be tested and inspected according QC/T645-2000 requirement, and check if tow truck structure, performance and reliability meet designing requirement. Test result should be identified by tow truck manufacturer and National special truck isolation. Identified tow trucks can be carried mass production. |
