In the eyes of many industry people, after a series of preparations and accumulations such as questioning, controversy, enlightenment, follow-up, trial and error, 2016 is regarded as the new first year of China's automobile intelligent interconnection development, including product form, business model and industrial trend. In many aspects, it will enter the stage of substantive development and move from concept to landing. 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.

Speed â€‹â€‹up the pace. More and more vehicles will be connected in real time, access online services, contribute data content, and enjoy the derivative value generated by big data; based on common interests and mutual understanding, the automotive and Internet industries will find a basis for cross-border collaboration.
The shuffle is intensified. Internet-connected applications and services will tend to be user-oriented, gradually phasing out the ribs, from the front-end of the OEM to small-scale smart hardware startups; the first batch of Internet-built teams will finish their first life cycle, but then they will survive, but then Dead, the left is king.
On the occasion of the great change, Che Yunyin visited many authoritative figures in the industry and summed up the top ten trends of China's automobile intelligent interconnection in 2016. I would like to make predictions.
Ten major trends 1. Accelerated integration of industry ecology All parties in the industrial chain, including car companies and Internet companies, will be more active in cross-border cooperation and integration. For the relatively conservative car manufacturers in the past, accelerating cooperation with Internet applications, finance, insurance, used cars, various price comparison service providers, and even certified offline service providers can actually help their interests to win.
2. Data openness enhancement Data openness is the basis for the emergence of valuable business models in the Internet of Vehicles. At present, Internet companies and startups have always been open to data, while car companies that were originally considered to be open to data are Under the premise of not leaking secrets and not jeopardizing vehicle safety, if a benign model of mining data can be found, the attitude towards data will also be open.
3. New business models emerge With the increase in applications and the accumulation of users, the business model of smart connected products will change, and even free models will emerge. Specifically, hardware, software, and service providers in the front-loading field provide products to car companies free of charge, and auto companies use open data to report; after-installation hardware is lower than cost sales, in order to obtain more users and generate data. It is a high probability event.
4, the second generation of car network to open If navigation, call center and other products are called the first generation of car networking, then based on active security, camera, radar, control, induction and other tightly coupled second-generation car networking products will accelerate development. It is worth noting that in the excessive process of the Internet of Vehicles products, some chicken ribs that did not meet the user's in-car usage habits will be gradually eliminated.
5. Localization development and cooperation Joint venture brands, luxury brands are more inclined to work closely with local car networking companies, and began to consider the product orientation of the Chinese market. For example, when foreign automakers are looking for TSP suppliers, they will prefer domestic suppliers that meet the standards, so that the overall product application and services are more suitable for Chinese users.
6. Reconstruction of TSP infrastructure The car factory network service has gradually changed from a single self-built mode to a hybrid cloud architecture of the car factory's own platform + private cloud + public cloud. From a certain perspective, the change of the TSP infrastructure is the inevitable result of the technical demand after the user's demand for the product changes, the openness of the data is enhanced, and the value of the business model is derived.
7. Smart hardware gradually matures With the addition of BAT and other big gold owners, the purchase cost of intelligent hardware users will be further shared, the product experience will be optimized, and more and more intelligent hardware categories will enter the host factory system. On the other hand, the rear-mounted intelligent hardware has the coverage advantage that the pre-installed products do not have, so all parties will gradually improve the products in order to cover the users and obtain data.
8. Further awakening of user needs On the one hand, with the popularization of pre-market education work and the improvement of product power, more and more users will have an interest in smart connected products; on the other hand, with the intelligence of front-loading and post-installation The interconnected products are gradually becoming mature from the green, and the user demand will be positively related to the enhancement of product strength.
9, the Internet car facing the reshuffle The first batch of Internet car team will finish the first life cycle, after the birth, but die, only the team with more funds and resources can survive. At present, capital and talent, R&D, and manufacturing are all strongly related. In the case of low orders in the early stage of enterprise development, resources directly determine the cooperative attitude of all parties in the supply chain.
10. National policy and strategic support Policy support will include two aspects of relevant technical standards development and infrastructure construction. At present, in addition to the introduction of the relevant standards for vehicle networking in the Informatization Service Industry Alliance (TIAA), from the national level, the Ministry of Transport is working on the development of relevant standards, and the Ministry of Industry and Information Technology is also planning to launch the development plan for the Internet of Vehicles.
Car cloud summary:
In 2016, it is destined to be a year of substantial integration of China's smart connected cars, from bottom to top, from the table to the inside. We hope and believe that the constant changes will break the shackles, rebuild the ecology, and derive the value. We are fortunate to stand on the side of this great change and follow each other. Behind the top ten trends, the answer is looming and confusing. The big change behind the answer is in the moment.
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.
In the eyes of many industry people, after a series of preparations and accumulations such as questioning, controversy, enlightenment, follow-up, trial and error, 2016 is regarded as the new first year of China's automobile intelligent interconnection development, including product form, business model and industrial trend. In many aspects, it will enter the stage of substantive development and move from concept to landing.
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.
