Product Introduction

The V-type spring clip fastener is a bolt fastener developed to meet the requirements of high-speed railway track circuits and the need to adjust the resistance of fasteners on bridges. The biggest difference between it and the II-type spring clip fastener is that the sulfur anchored spiral spikes are replaced by spiral spikes and embedded sleeves to improve the insulation performance of the fastener. At the same time, the gauge baffle no longer buckles the bottom of the rail but only presses against the side edge of the bottom of the rail, thereby reducing the length of the spiral spike and reducing the eccentric force of the bolt.

The V-type spring clip fastener consists of spiral spikes, flat washers, spring clips, rail pads, gauge baffles and embedded sleeves (which have been cast in the sleepers when the sleepers are manufactured). As shown in the figure, the right side is for the need to adjust the height of the rail, and there is also a height adjustment pad.

Fastener system components

There are two types of elastic clips: the W2-type elastic clip used in general sections and the X3-type elastic clip with low clamping force that may be used on bridges. The W2-type elastic clip has a diameter of 14 mm, a clamping force of 10 kN, and a spring stroke of 12 mm; the X3-type elastic clip has a diameter of 13 mm, a clamping force of 4.5 kN, and a spring stroke of 8 mm.

Under-rail pads are divided into two types: rubber pads and composite pads. The former is used in general sections, and the latter is used in sections requiring low fastener resistance.

Gauge retainers are made of glass fiber reinforced nylon 66 and are divided into seven models: No. 2, No. 3, No. 4, No. 5, No. 6, No. 7, and No. 8. Models 4 and 6 are used for standard gauge.

Height-adjusting pads are available in four specifications according to thickness: 1 mm, 2 mm, 5 mm, and 8 mm, and are placed between the under-rail pad and the rail-bearing surface of the sleeper.

Product performance advantages

Superior structural stability: The shouldered design combined with bolt fastening provides strong lateral restraint capability. Compared with the shoulderless Type IV system, it can more effectively control rail displacement in heavy-load or curved sections and reduce deviations in track geometric parameters.

Enhanced Stability & Safety: The system ensures consistent clamping force, reducing the risk of rail displacement or misalignment, which is critical for high-speed (up to 350 km/h) and heavy-load operations.

Superior Elasticity & Vibration Damping: Type V systems (and related elastic clips/pads) absorb impact and vibration, increasing passenger comfort and reducing wear on components like sleepers and rails.

Reduced Maintenance & Costs: Designed for easier installation and replacement, reducing downtime. High-quality materials ensure long-term durability.

Environmental Resilience: Specifically designed to withstand varied conditions, including high-speed and heavy-load scenarios, while offering reliable performance.

Compatibility: It is widely used in both ballasted and ballastless track systems, often serving as a flexible, cost-effective, or upgrade option in mixed-traffic scenarios.
