Chain Drive Systems

it’s what we do

Catensys manufactures chain drive systems for any vehicle using combustion and/or hybrid engines with six key elements in mind: sound, weight, durability, precision, friction and costs.

Each link in each chain, each tensioner, guide and sprocket is a result of extensive know how, many years of experience and active R&D. Focusing on our customers’ challenges we have developed and keep improving our high quality products which specifically feature low noise and friction, high durability, temperature resistance and a very competitive cost:performance ratio.

Catensys has a comprehensive range of high-quality components for any customized chain drive systems:

Catensys has a comprehensive range of high-quality components for any customized chain drive systems:

Chains

Due to the extremely high demands of modern high-power engines, Catensys timing chains are specially designed and manufactured to meet and often exceed these high requirements.

  • Wear resistance can be optimized by means of pin specification (e. carbonitrided or vanadized) and bush specification
  • Curved back plates for optimized friction characteristics
  • Bush and roller chains feature outer link plate contour with optimized friction characteristics and low-noise gear meshing {chain and sprocket) due to optimized gear tooth geometry
  • Inverted tooth chains feature outer link plate contours with optimized friction characteristics available

Advantages

  • High variability due to different pitches, lacings & plate width
  • High wear resistance over lifetime
  • Increased strength due to improved surface finish
  • Excellent strength/width-ratio
  • High stiffness (among others by press fitted middle plate)
  • Improved NVH behaviour
  • Low friction losses by optimized joints and contact areas

Tensioners

Features

  • Hydraulic chain tensioner comprising a locating housing made from die-cast aluminum with an external resettable locking ring system
  • The non-return valve is integrated into the locating housing
  • The piston is designed with external latching grooves with which the locking ring engages
  • Hydraulic damping is precisely adjusted via the leakage gap between the aluminum locating housing and the piston
  • A pressure control valve can optionally be used to limit the maximum forces

Advantages

  • Ratchet system for the reliable prevention of tooth slip-off in critical timing drives
  • Cost-optimized, flexible design
  • Transport retaining device for simple initial mounting
  • Virtually constant leakage gap length
  • Resettable in any desired operating position for servicing purposes
  • Solutions for different tensioning directions (de-aeration) are available

Guides and Blades

Features

  • Tensioning blade at the slack side for pre-tensioning the chain and for damping dynamics by means of a chain tensioning element
  • Chain Guide at the tight side for chain guidance
  • Tensioning blades and chain guide in a wide range of designs, e. g. 1-component solutions, 2-component solutions made from temperature-resistant plastics – snap-fitting or injection molded around an insert with carrier bodies made from glass fiber-reinforced plastic, aluminum, or sheet metal
  • The sliding layers in the chain contact zone are made from wear resisting plastics with optimized friction characteristics

Advantages

  • Design, calculation, testing, and volume production from a single source
  • Tailormade for every application and design envelope requirement
  • Optimized solutions in terms of weight and costs
  • Low friction characteristics in the timing drive

Sprockets

Features

  • Transmission of torque (from crankshaft/camshaft to timing drive) using friction locking
  • Surface structure applied to the end face
  • Different material variations are possible, g. steel or sintered material

Advantages

  • Fast implementation is possible, as no design change is required
  • Low-cost solution with easy handling
  • Replaces additional elements (e. g. diamond wheels) for increasing friction in the clamping area
  • Increases the torque that can be transmitted by up to 250 % compared to the standard design
  • Thus enables increased torque transmission, g. for PO hybrid applications

A legacy of superior standards

Aside from the more than 150 patents Catensys holds, we constantly strive to live up to and continue this legacy. Our highly engineered chain drive systems operate in harshest environments and meet or surpass stringent NVH standards.
