The car parking pawl is a crucial component used in automotive transmissions to engage the parking gear and prevent vehicle movement when parked. It provides a mechanical locking mechanism that ensures the vehicle remains stationary and secure.

Description
The car parking pawl is a small, toothed metal component located within the transmission assembly. It engages with the parking gear or parking plate to lock the transmission output shaft, preventing rotation and keeping the vehicle stationary. When engaged, the parking pawl securely holds the vehicle in place until it is manually disengaged during the starting process.

Specifications
Car parking pawls come in various specifications to match different transmission designs and vehicle models. The key specifications include dimensions such as length, width, and thickness of the pawl's teeth and overall size. The number and shape of the teeth are essential to ensure proper engagement with the parking gear for effective immobilization.

Common Standard Sizes
Standard sizes for car parking pawls can vary depending on the specific transmission manufacturer and vehicle model.

Common standard sizes often include lengths ranging from approximately 2 inches (5 cm) to 4 inches (10 cm), widths averaging between 0.5 inches (1.3 cm) and 1 inch (2.5 cm), and tooth thicknesses between 0.1 inches (0.25 cm) and 0.2 inches (0.5 cm). It is important to note that these sizes can differ based on the transmission type and application.

Materials and Manufacturing Process
Car parking pawls are typically made from high-strength materials capable of withstanding significant loads and providing reliable operation. Commonly used materials include hardened steel alloys, such as carbon steel or stainless steel. The manufacturing process involves precision machining techniques to create the desired tooth profile and overall shape of the pawl. Heat treatment processes, such as quenching and tempering, are often applied to enhance the hardness and strength of the pawl teeth.

Installation and Usage
Proper installation and usage of the car parking pawl are crucial for safe and effective parking. The parking pawl is installed within the transmission assembly, typically near the output shaft. When parked, the driver engages the parking pawl by shifting the transmission into the "P" (Park) position. It is important to use the parking brake in conjunction with the parking pawl for added security. Routine maintenance and inspections are necessary to ensure the parking pawl's teeth are in good condition, free from wear or damage.

Processing advantage

1. The spiral blade produced by the continuous cold rolling method overcomes the shortcomings of the traditional spiral blade production process, such as poor precision, difficult forming and high consumption of materials, and low production efficiency.

2. After the blade is formed, the surface is smooth and the dimensional accuracy and surface hardness are high.

3. Provide continuous integral blades according to the helical length required by customers, with good rigidity, convenient and fast welding and assembly during use.
