The number of mounting points depends on the length, mass, use and installation of the power assembly. The mounting system can be mounted at 3, 4 and 5 points. Generally, three-point and four-point mounting systems are used in automobiles, because if the number of mounting points increases when the vibration is relatively large, when the body deformation, some mounting points will be dislocated, so that the engine or mounting bracket force is too large and cause damage to the three points, the advantages of the support is that no matter how bumpy and jumping the car, it can always ensure the support. The point is in a plane, which greatly improves the force condition of the body. The front and rear suspensions of the four-point mount are mainly used to prevent the torsion of the power assembly, and the torsional stiffness is larger than that of the three-point mount.

Three point mounting system

Left suspension: connect with gearbox, mainly power assembly limit and supporting function.

The right suspension: connected with the engine, it can isolate the engine, such as vibration, inertia force and vibration.

Rear suspension: It is connected with the gearbox, and has the functions of longitudinal limit, bearing torque, driving condition limit and so on.

Four point mounting system

It can overcome the large torsional reaction force, but the torsion stiffness is large, which is not conducive to the isolation of low frequency vibration.

Left and right suspension: close to the torsional inertia axis, support the powertrain up and down, and have the function of vibration decoupling.

Front and rear suspension: with the transmission, it has longitudinal limit, driving condition limit and torque endurance.

      Eckes Takes Points Lead with Top-Five Performance in Texas
      By NAPA
      Christian Eckes took the NASCAR CRAFTSMAN Truck Series points lead on Friday night with a stout fourth-place performance at Texas Motor Speedway. The driver of the No. 19 Gates Hydraulics Chevrolet Silverado RST captured his third top-five finish of the season and scored 50 points on the night, the second-most of all drivers in the field. Eckes led 31 laps, the only driver to have led laps in each race this season, and tallied his third top-five finish in the last four events.
      For the second-consecutive weekend, Eckes qualified on the front row and was a mainstay in the top five for the entire event. He settled into second at the drop of the green flag and challenged for the lead near the midway point of the opening stage. The first lead change of the night occurred when Eckes powered his Gates Hydraulics Chevy to the lead on lap 17 and paced the field for 21 circuits. He surrendered the lead on lap 38 and collected nine points at the end of Stage 1 on lap 40 while running second.
      Crew chief Charles Denike brought Eckes to pit road under the stage caution for four fresh tires, fuel, and a minor air pressure adjustment to tighten his balance. Eckes restarted second on lap 47 and maintained position inside the top five for the ensuing 35-lap run. An improved handling balance and consistent lap times netted Eckes another eight points at the end of Stage 2 on lap 80 by running in third position.
      Eckes was armed with another batch of fresh tires, fuel, and minor adjustments to fine-tune the handling during the second stage caution. After restarting third on lap 87, he waged war for the runner-up position and gained control of it by lap 100. He ran there until a cycle of green flag pit stops began on lap 119. Eckes made his final stop on lap 129 just before a caution waved. He was able to stay on the lead lap in fourth position and in contention for the victory. He made another fierce run for the race lead on a lap 150 and led until lap 158. During the final 10 laps, Eckes fought valiantly for one final charge at the lead but took the checkered flag in fourth position for his third top-five and sixth top-10 of the season.
      “Not a bad points night,” Eckes said. “I thought we’d have a pretty good shot at the win there, but just went down into Turns 1 and 2 and got way too tight and slid up the racetrack. It is what it is. I’m proud of the No. 19 Gates Hydraulics team for making the improvements that they did. Our mile-and-a-half stuff has definitely shown a little bit of an improvement. We still have a little bit of a ways to go, but we’ll see how it goes.”
      Start / Finish: 2 / 4

      Elliott Maintains Top-10 Points Position after Phoenix
      By NAPA
      Chase Elliott and No. 9 Kelley Blue Book team qualified third for Sunday’s NASCAR Cup Series race at Phoenix Raceway The 28-year-old driver earned valuable stage points, finishing fifth in stage one and seventh in stage two A slew of cautions in the final stage prompted multiple strategies among teams. Elliott restarted 17th after the final caution of the race and ultimately finished the race in the 19th position Elliott and the No. 9 team leave Phoenix ninth in the Cup Series points standings After posting the seventh fastest lap in Friday afternoon’s NASCAR Cup Series practice session at Phoenix Raceway, Chase Elliott backed that up with a third-place qualifying lap on Saturday. The 28-year-old driver took the green flag for the 312-lap race from the second row on Sunday afternoon. Elliott was still running inside the top five when the first caution flag of the race waved on lap seven. The early report from the Hendrick Motorsports driver was that his No. 9 Kelley Blue Book Chevrolet Camaro ZL1 was locked down and tight in the back. With the team opting not to pit, Elliott restarted in the fifth position on lap 12 and remained there as the rest of 60-lap first stage went caution free. The fifth-place stage finish garnered six stage points for the Dawsonville, Georgia, native.

      Under the stage-ending caution, Elliott relayed to crew chief Alan Gustafson that the Kelley Blue Book Chevy was tight and that it freed up as the run went on. The crew opted for four tires, fuel and a chassis adjustment during a fast pit stop which gained Elliott a spot on pit road. He lined up fourth to start the second stage on lap 69. Elliott raced three-wide once the field went back to green, taking over the third position on lap 70. He held strong, maintaining his top-three running position through a long green-flag run. The field started making green-flag pit stops on lap 115, with Elliott bringing the Kelley Blue Book Chevrolet to pit road on lap 117 for four tires and fuel. With the field stretched out, Elliott was bogged down in traffic following his stop, making it harder to gain track position. Still, he managed to score a top-10 finish in the second stage, taking the green-and-white checkered flag in the seventh spot. The result added four more stage points to his total. 

      During the stage break, Elliott brought the Kelley Blue Book Chevrolet to pit road for four tires and fuel. The pit crew knocked out another fast stop, gaining the 2020 Cup Series champion three spots. Elliott took the green flag for the final stage from the fourth position on lap 194 and was scored in fifth place when the caution came out just two laps later. Elliott kept his Chevrolet on the track under the yellow flag. He lined up fifth for the restart on lap 202 and was battling inside the top 10 when the race was slowed once more. Staying out while some drivers deeper in the field visited pit road, Elliott restarted eighth and was scored in ninth at the time of the lap-216 caution. Gustafson called Elliott to pit road with the rest of the leaders for four tires, fuel and a chassis adjustment. With varying pit strategies among teams – some taking only two tires and others opting to stay out – Elliott restarted in the 17th position on lap 220. He managed to advance as high as 16th early in the run but being stuck in dirty air made it difficult for Elliott to continue forward progress. When the checkered flag waved on lap 312, he was scored with a 19th-place finish.

      Elliott and the No. 9 team leave Phoenix Raceway ninth in the Cup Series points standings, just 28 markers behind the leader.

      Eckes Starts 2024 with Great Points Day amongst Daytona Chaos
      By NAPA
      A resilient effort by Christian Eckes and the
      link hidden, please login to view team salvaged a top-10 finish in the NASCAR Craftsman Truck Series (NCTS) opener at Daytona International Speedway on Friday night. The driver of the No. 19 NAPA Auto Care Chevrolet Silverado RST finished 10th despite being involved in three multi-truck accidents in the second half of the event. His 10th-place result earned him 39 points and places him third in the NCTS championship standings.
      Eckes was buried deep in the field after qualifying 25th, but he instantly darted toward the front once the green flag flew. Eckes’ aggression was immediately evident as he made three-wide moves on the opening lap. He narrowly avoided a multi-truck accident on lap six and joined the top-10 on lap 13. A one-lap dash to close Stage 1 saw Eckes grab three points in eighth position on lap 20.

      Crew chief Charles Denike kept Eckes on track during the caution to inherit track position and found themselves in the mix for the race lead when Stage 2 went green at lap 27. Eckes was in the thick of the battle for the race lead and pushed his new MHR teammate Tyler Ankrum to the Stage 2 win. Eckes pocketed another nine points by running second at the end of the segment on lap 40.

      Under the second-stage caution, Eckes pitted for four tires and fuel and restarted 12th on lap 45. A caution on lap 57 allowed him, and several other competitors, to make their final stop for fuel. Eckes restarted 16th on lap 62 and rocketed to the front with some aggressive drafting. He briefly took the lead on lap 72 but was involved in an accident on lap 79 while running second. Despite losing a lap, the NAPA Auto Care team made ample repairs and allowed Eckes to regain his lap on lap 86. With five laps to go, he suffered minor damage in an incident which set up an overtime restart. After restarting 24th with two laps remaining, Eckes drove halfway back through the field but was swept into a track-blocking accident on the final lap and suffered significant damage.

      Eckes was able to refire his Chevrolet Silverado RST and drove back around to the checkered flag to finish 10th and start the season just four points out of the championship lead.

      “Tonight was a wild night, for sure,” Eckes said. “We were able to drive our NAPA Auto Care Chevrolet up to the front a couple times and were going to be one of the trucks to beat. I was able to work well with our teammates for a while tonight until we got turned off Turn 4 there with 20-to-go or so. I’m proud of the guys on our NAPA team to get it fixed and got our lap back. We never gave up tonight and we saved a ton of points because of it.”
