On July 1, 2018, the illegal car was forbidden to go on the road. The domestic car market car finally bid farewell to the situation of over-limitation in the past. The road safety hazard caused by the illegal car was completely eliminated, which also symbolized the domestic The transportation environment is developing in a positive way. After the illegal car is cleared, the compliant car is basically divided into three camps: flat head traction + trailer, long head traction + trailer and center axle car. The three models correspond to the requirements for loading 6, 7, and 8 new regulations. Their existence also reflects the different views of the new and old models and the driver group's policy in addition to the policy landing process. The car can be made into different lengths according to customer requirements. The frame is welded I-beam, and the whole body is fully automatic submerged arc welding and carbon dioxide gas shielded welding. After the welding is completed, shot peening is performed to eliminate the welding stress and improve the adhesion of the paint surface, so that the quality is stable and the appearance is beautiful. The upper chassis can be divided into two to three blocks, and the height is adjusted by the chain hoist and the cylinder. The closed front piece is made of stamped small corrugated board skin, the side is made of small corrugated board or stamped corrugated board skin, and the top is equipped with awning rod and tarpaulin. The whole vehicle is equipped with a toolbox, a spare tire frame, and a drip brake system to improve the safety of vehicle transportation. Carriage classification According to the car structure of the car, we can divide the car into three types: skeleton, semi-enclosed and fully enclosed. According to the rear axle structure of the car, we can divide the car into two axes. Single tire type, double shaft double tire type, etc. Skeleton type, that is, the side piece is composed of a column, no side mask, no front piece, back door and top piece. This type of car has its own light weight, low cost and low fuel consumption, but it is inconvenient to transport goods and the car is vulnerable to damage. The fully enclosed sedan, that is, the side panels and the front panels are all closed with a mask, with a rear door, and the top panel is a poncho-type cloth. The car is self-contained, costly and fuel-efficient, but it can protect the car and transport other goods; Semi-enclosed car, that is, no top piece, its characteristics are between the two. The two-axle single-tire car, that is, the rear axle is a two-axle structure with 2 tires per axle and a total of 4 tires. The axle of this structure is designed as a concave bridge, so that the perforated plate above the axle is low from the ground, which increases the loading space. The twin-axle twin-tire car, that is, the rear axle is a two-axle structure with 4 tires per axle and a total of 8 tires. The axle of this structure is designed as a common axle and adopts a reverse-mounted suspension device, so that the perforated plate above the axle is very high from the ground, generally 1250 mm, and the loading space has an influence, but the bearing capacity is increased. 2. The main structure of the car 2.1 The structure of the car is generally divided into lower chassis, upper chassis, side panels, front panel, rear door, top panel, accessories, hydraulic system, suspension system, air brake system, circuit system, support device, hub cooling system, etc. composition. 2.2 Due to the limitation of the size of the vehicle by the national standard, in general, the size of the car's outer dimensions is small, and the actual size of the actual production of the vehicle is too large, the front overhang, the wheelbase, the rear overhang and the announcement. Also inconsistent, pay attention when signing the contract. In order to facilitate the entry of the vehicle, the car is usually designed in the length direction of 3 segments, the middle segment can be removed, and the front and rear segments are connected to ensure that the total length meets the announcement size. 2.3 The car is a double-deck loading platform structure. The upper loading platform can be lifted up and down under the action of the lifting device to facilitate loading. The lifting device is configured according to different needs, and can be divided into three types: hydraulic cylinder direct lifting type, pulley wire rope pulling lifting type and chain hoist hanging type. 2.4 For the two-axle single-ticket car, the front end of the lower frame is designed with one manual springboard on the left and right sides, and the rear tail is designed with a ladder and a ladder. The rear upper frame is designed with a ladder at the rear. 2.5 For the twin-axle twin-tire car, the front end of the lower frame is designed with one manual springboard on the left and right sides. The front of the rear axle is designed with a movable frame for lifting the cylinder. The rear of the rear axle is designed with one manual springboard. The rear part is designed with ladders and ladders. The rear upper frame is designed with a ladder at the rear. 2.6 About the chassis mask. The middle of the lower chassis is equipped with a mask, t1.5; under the traction pin (tractor tire) and the rear plate at the rear plate, the mask t1. The rest of the lower chassis and the upper chassis are not covered. 2.7 In order to prevent the upper chassis from jumping, a tight rope device is provided to pull the upper chassis and the lower chassis. 3. Main configuration 3.1 Limitation and fastening of commercial vehicles Before the vehicle is transported, the vehicle must be restrained and fastened to avoid the vehicle's beating during driving, ensuring the safety of the vehicle during driving. There are two ways to fix the vehicle according to the form: one is the wheel fixing method, and the other is the frame fixing method. The wheel fixing method uses a car tire limiter and a car tire retractor to catch the tires and prevent the goods car from moving back and forth. The limit frame is a standard steel tube structure. The lower hooks are placed on the adjacent holes of the perforated plate, and the plate type limit frame is optional. The frame fixing method fixes the frame of the commercial vehicle and the frame of the car to prevent the vehicle suspension device from jumping up and down. The fixing method is adopted when the gap between the top of the product vehicle and the upper chassis or the ceiling is too small, and is implemented by the user as needed. Standard configuration: car with total length ≥ 15m, car tire limiter, 32, car tire retractor 32; total length <15m car, car tire limit frame, 24, car tire retractor 24 only. 3.2 chain hoists The chain hoist is used to lift the upper frame, and the standard configuration is 1t, 2 pieces. For fully hydraulically lifted vehicles, it is not equipped with a chain hoist. 3.3 Hub cooling device The standard configuration does not include hub cooling (although the actual vehicle is already equipped with a water tank). If necessary, it must be stated on the contract. 3.4 spare tire carrier The spare tire carrier adopts a door structure. That is, the spare tire is fixed by two bolts on the door. Two gantry spare tire carriers are standard.
