Introduction of Lifters to Rear Dampers
NASCAR’s decision to introduce lifters for rear dampers represents a tactical improvement aimed at mitigating the challenges posed by flat tire incidents during races. The implementation of these lifters, set to begin at Michigan International Speedway, is a response to the inherent vulnerabilities associated with the Next Gen car‘s design, particularly concerning flat tire scenarios.
Historically, flat tires have proven detrimental to a driver’s competitive standing and to the vehicle’s structural integrity, specifically the underbody. When a car becomes “beached” due to a flat tire, the potential for severe damage increases considerably. This situation can lead to lengthy recovery processes, ultimately detracting from the complete racing experience and event timeliness.
The introduction of lifters is intended to improve the car’s ability to recover from such incidents by providing extra support to the rear dampers. This adjustment aims to facilitate a more efficient shift back to a functioning state, minimizing downtime and damage. By leveraging this innovation, teams can potentially avoid the extensive underbody damage that has characterized prior flat tire experiences, thereby preserving vehicle performance throughout the race.
Furthermore, this proactive measure reflects NASCAR’s commitment to continually improving vehicle design and race safety. The lifters not only serve a practical purpose but also denote a calculated evolution in race car engineering, aligning with the series’ ongoing efforts to improve competitive integrity and driver safety in the face of unforeseen racing challenges.
Purpose and Benefits of the Lifters
The introduction of lifters serves a critical purpose in improving the recovery process for vehicles experiencing flat tires, facilitating efficient towing while minimizing potential damage to the car’s underbody. This cutting-edge system enables a vehicle to be raised just a few inches off the ground, greatly enhancing accessibility for safety crews tasked with towing.
As emphasized by NASCAR senior vice president of competition Elton Sawyer, the lifter is integrated into the rear of the car and operates in conjunction with the shock absorber, thereby streamlining the recovery process.
“It’s a system that’s on the rear of the car; it works around the shock absorber, As everyone knows, the Next Gen has been really, really good for our racing. I think we’ve had some phenomenal racing. What came with that and we noticed that immediately at Auto Club two years ago, is when this car has a flat tire or four flats particularly, it can’t go anywhere.” – Sawyer
One of the primary benefits of the lifters is their role in addressing a persistent challenge faced by the Next Gen cars. When these vehicles suffer from a flat tire, particularly when multiple tires are affected, they become immobile, presenting difficulties for recovery. The lifters provide a solution by allowing the car to be lifted, ensuring that towing is executed without excessive effort or risk of further damage.
Moreover, this system improves safety for both the drivers and the recovery teams. By raising the vehicle, the lifters reduce the likelihood of injury during the recovery process, as crews can operate more efficiently and with greater control.
Technical Details and Implementation
Integrating advanced technology into the Next Gen car, the lifter system is designed to improve the recovery process by utilizing a quick connect mechanism that allows track service workers to efficiently lift vehicles with minimal disruption. This groundbreaking assembly involves a collaboration with Öhlins, the Cup Series shock absorber vendor, ensuring that the system meets the rigorous demands of NASCAR racing.
“There’s a quick connect that will be connected or installed along the A-post of the Cup cars that when the track service worker gets there, they basically can take an air hose, if you will, and pump that up to the rear and the tire will lift up and then gives the drivers the ability to drive back to pit road.”
“Today, we’re having to hook them up or push them; we’re way too far in the middle or deep end of having to get cars back to pit road so they can start their service. So, [we’re] trying to keep that more on the team’s side.” – Sawyer
The lifter system operates by connecting an air hose to a quick connect installed along the A-post of the Cup cars. Once activated, this mechanism raises the rear of the vehicle, enabling drivers to navigate back to pit road for crucial service. This design philosophy aims to streamline recovery procedures considerably, shifting from traditional methods that require manual intervention.
Key features of the lifter system include:
- Quick Connect Mechanism: Facilitates rapid attachment to vehicles, minimizing downtime.
- Air-Actuated Lift: Employs pneumatic technology for efficient lifting of the car.
- Integrated Design: Seamlessly fits into the existing Next Gen car architecture.
- Improved Safety: Reduces physical strain on track service workers during tire recoveries.
Operational Procedure for the Lifters
Operational efficiency during tire recoveries is greatly improved by a streamlined procedure for utilizing the lifters, which begins with connecting an air hose to the vehicle’s quick connect mechanism. This initial step is essential, as it allows for the rapid deployment of the lifters, which are designed to raise the rear of the vehicle. Once the air hose is securely attached, a controlled release of air activates the rear lifters, effectively lifting the car from its resting position.
“As we get to the incident, plug in there, put a little air to the rear lifters that basically picks up the back of the car. Then, when they get to pit road, there’s a valve there. They just hit the valve and the rear of the car will go back down.” – Sawyer
Upon reaching the pit road, the operational protocol necessitates that the team engages a designated valve. This valve serves to release air from the lifters, allowing the rear of the car to descend back to the ground in a controlled manner. The ability to quickly raise and lower the vehicle not only minimizes the duration of the tire change but also improves the safety of the crew members involved in the operation.
Additionally, the lifters are engineered to provide stability during the recovery process, reducing the risk of accidental slips or falls. This systematic approach guarantees that all crew members are well-coordinated in their actions, ultimately leading to a more efficient tire recovery process.
Previous Attempts and Challenges
Previous efforts to address flat tire recoveries in NASCAR faced considerable challenges, as illustrated by the attempted implementation of a dolly system during practice at Iowa Speedway. This system was tested when Ross Chastain experienced a flat left rear tire on the track. The recovery process, however, proved to be laborious and inefficient, ultimately leading NASCAR to conclude that it was not a viable solution for use during competitive racing.
The dolly system encountered several obstacles, including:
- Time Consumption: The extended duration required for setup and execution detracted from the race’s pace.
- Operational Complexity: The logistics of deploying the dolly system effectively during a high-stakes environment introduced notable complications.
- Staff Training: Crews would require extensive training to efficiently utilize the dolly, further complicating the recovery process.
- Equipment Reliability: Concerns over the durability and reliability of the dolly equipment in varying track conditions were paramount.
News in Brief: NASCAR to Introduce Lifters
The introduction of lifters at Michigan International Speedway represents a noteworthy advancement in NASCAR’s flat tire recovery processes.
By employing pneumatic technology and a quick connect mechanism, these lifters improve safety and efficiency for both drivers and recovery teams.
This innovation minimizes downtime during races and addresses previous challenges associated with vehicle recovery.
Altogether, the implementation of lifters highlights NASCAR’s commitment to improving operational procedures and ensuring a safer racing environment.
