A few days ago, Hengtian Automobile Co., Ltd., located in Suizhou, had a major contract fraud case. The cause of the incident was that a dealer who had frequent cooperation with the Hengtian Group introduced to the company an order of 20 sets of 8 dump trucks worth more than 4 million yuan. The customer promised to pay the vehicle within 10 days after the vehicle was delivered, but after 10, the Hengtian Group has not received the payment. After the Hengtian Group reported the case, after investigation by the public security agency found that because the car buyers owed more than 9 million yuan in debt, these vehicles were used to make mortgage financing. Fortunately, the last 20 dump trucks were all recovered. Although things are in danger at the end, such matters as contract fraud are worthy of attention within the entire private car industry. Then, how do special vehicle companies and distributors prevent contract fraud from happening? There must be principles for signing contracts First of all, companies must pay great attention to signing contracts. For large orders involving large sums of money, special vehicle companies or dealers need to check with the company's lawyers when signing contracts, and strictly follow the requirements of the contract. Companies and dealers should not give up the principle that they should be because the orders are too tempting. Some users have moved their brains out of the car in order to allow the car to pull goods. As a special-purpose vehicle company at this time, it must have a very clear sense of law, and all orders that violate national laws and regulations must be resolutely abandoned. Because such a contractual agreement is ultimately invalid. Comprehensive understanding of car buyers information The payment method of the user is related to the final payment situation. In general, there are three payment methods for individual users to set a car, namely, the way of paying the car after the first payment, the car to the payment and the deposit plus the final payment. In most cases, the user’s payment method tends to pay a portion of the deposit first, and the payment is paid after the vehicle arrives. For car buyers who often cooperate with companies, their payment method is usually car to payment. If the user is paying the full amount before picking up the car, then the company and the dealers can have a good night's sleep, but this situation is generally very small. In most cases, the deposit is added to the balance. This situation is more risky for the enterprise. Therefore, the special vehicle company and sales personnel should minimize the amount of the final payment, so that even if the final payment is difficult to recover, the impact on the company and individuals Not too much. If it is car-to-pay, then companies need to sign a payment agreement with the car buyer in advance. Of course, with this agreement, there is no guarantee that the final payment can be successfully recovered. This requires companies to have one more eye and one more investigation. Enterprises and marketing personnel must understand the economic strength and social credit status of car buyers in many aspects. The contract fraud case that Hengtian Group emerged was largely based on the fact that the user’s economic situation was not understood in advance, but it was based solely on the trust of the better-disposed dealers. Where are the funds for the unit order? Orders of government and government agencies due to the large volume of purchases, the amount involved is large, the payment method may be to take a part of the deposit in advance, after the car to pay the final payment. Therefore, when signing a contract with government and government agencies, the company needs to know more about the sources of funding for government and government agencies. If it is the country's special procurement funds and project funds, companies can safely sign contracts with these units. However, if the source of funds is the self-financing of government and government agencies, enterprises must be very careful when signing contracts with these units. As far as the entire private sector is concerned, the situation of non-receivable receivables is prevalent in every enterprise. Because of this, special car companies and dealers have a good understanding of the requirements of car buyers and car buyers, the signing of car purchase contracts, and the source of funding. The so-called aligning bearing is that the raceway raceway is spherical, and it can adapt to the angular displacement between the two raceways, which is mainly supported by radial load, and can also bear a small number of two-way axial loads.

Characteristics of core bearing
It is mainly subjected to radial load, and it can also bear a small amount of bidirectional axial load.
The center ball bearing is the inner ring of the two raceways and the outer ring of the raceway for the spherical surface, and the ball bearing is assembled with a ball shaped roller. It can bear a large radial load and also bear a certain axial load, as shown in Figure 1. The outer raceway of this kind of bearing is spherical, so it has the performance of adjusting center.
The main features of the ball bearing are as follows:
(1) the outer race raceway of the ball aligning ball bearing is a part of the sphere. The center of curvature is on the bearing axis. Therefore, the bearing has the function of adjusting the center, and it can be automatically adjusted when the shaft and shell appear flexure, and does not increase the bearing burden.
(2) an appropriate amount of axial load that can bear radial load and two directions. But it can't bear the torque load.
This kind of bearing has smaller contact angle, almost no contact angle under axial load, small axial load capacity, large radial load capacity, and suitable for heavy load and impact load.
(3) the double row center ball bearing with tightened and locking nuts can be installed at any position on the optical axis and does not need to be positioned on the shoulder.
Spherical Roller Bearing is in the two groove of the inner ring and outer ring raceways between Spherical Bearing assembly, a drum shaped roller, as shown in figure 3. Spherical Roller Bearing with two rollers, mainly bear radial load, also can withstand any direction of the amount of axial load; radial load capacity is very high, especially suitable for radial heavy loads or vibration, but unable to bear pure axial load.
The main characteristics of the spherical roller bearing:
(1) bearing with self-aligning ball like outer ring spherical roller bearing raceway is a part of spherical surface, the curvature center on the bearing axis, the bearing outer ring raceway is spherical shape, so its self-aligning performance is good, can compensate concentricity error, thus can realize the automatic aligning.
(2) in the section perpendicular to the rolling direction, the roller busbar is a curve, which fits well with the inside and outside raceway. The roller and raceway are linear contacts, which can bear radial load and axial load, and has good impact resistance.
(3) roller and roller bearing raceway match well, and are therefore relatively serious curve generatrix, sliding, friction than cylindrical roller bearings, spherical roller bearings are allowed so low working speed.
(4) the heart fades with a normal roller bearing non symmetrical roller, it will generate an axial force, roller by the force and the center fixed flange contact, spherical roller bearing symmetrical roller, it can move along the axial direction using the middle movable baffle ring, so no longer block roller center the edge of the constraints, and saves the recess of the inner raceway, the roller can be used longer, so as to improve the bearing capacity.
(5) single row self-aligning roller bearing contact angle is 0. Under axial load, the contact angle did not change significantly, the axial load will be very small contact forces generated great between roller and raceway, so when the axial load is greater than the radial load, the loads of single row spherical roller bearing can bear radial and axial.
(6) bearing with self-aligning ball like set with tight double row spherical roller bearing can be installed in any position on the optical axis, do not need to process the positioning shaft shoulder.
